FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100 |
| 2 |
|
| 3 |
1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers. |
| 4 |
|
| 5 |
2. Support for inline blob encoding. Blob values pass using the "SetAsString" method |
| 6 |
will now be encoded inline (i.e. as part of the parameter buffer) if they are |
| 7 |
shorter than a pre-set limit. Longer values continue to be saved as blobs as a |
| 8 |
separate server interaction. This is intended as a performance optimisation. |
| 9 |
|
| 10 |
The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new |
| 11 |
IAttachment interface functions: |
| 12 |
|
| 13 |
function GetInlineBlobLimit: integer; |
| 14 |
procedure SetInlineBlobLimit(limit: integer); |
| 15 |
|
| 16 |
3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API |
| 17 |
user as the functionality is embedded in the implementation of the IStatement |
| 18 |
interface. Three new functions are defined: |
| 19 |
|
| 20 |
procedure AddToBatch; |
| 21 |
function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion; |
| 22 |
procedure CancelBatch; |
| 23 |
function GetBatchCompletion: IBatchCompletion; |
| 24 |
function GetBatchRowLimit: integer; |
| 25 |
procedure SetBatchRowLimit(aLimit: integer); |
| 26 |
|
| 27 |
Also |
| 28 |
|
| 29 |
function IsInBatchMode: boolean; {true after call to execute(eaDefer)} |
| 30 |
function HasBatchMode: boolean; {true if and only if IBatch Supported} |
| 31 |
|
| 32 |
For more information see the User Guide. |
| 33 |
|
| 34 |
4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages |
| 35 |
provided with the EIBInterBaseError now include all three parts. |
| 36 |
|
| 37 |
5. Firebird.pas and include files updated to Firebird 4.0.0 |
| 38 |
|
| 39 |
6. New IStatement method: function GetSQLStatementTypeName: AnsiString; |
| 40 |
Returns SQL Statement type as a text string; |
| 41 |
|
| 42 |
7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to |
| 43 |
an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger. |
| 44 |
|
| 45 |
FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100 |
| 46 |
|
| 47 |
1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a |
| 48 |
typo in FB30Statement.pas that caused an unknown parameter error. |
| 49 |
|
| 50 |
FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000 |
| 51 |
|
| 52 |
1. Imported (Firebird) constants updated for Firebird 4. |
| 53 |
|
| 54 |
2. Firebird.pas from Firebird 4 integrated into source code tree. |
| 55 |
|
| 56 |
3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types. |
| 57 |
|
| 58 |
4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision. |
| 59 |
|
| 60 |
5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider. |
| 61 |
QueryInterface may be used to coerce this interface from IFirebirdAPI. The |
| 62 |
interface provides a single method "function GetIMasterIntf: IMaster". This provides |
| 63 |
type safe access to the Firebird IMaster interface and avoids the need to turn |
| 64 |
off object checks when coercing "function GetIMaster: TObject" to IMaster. |
| 65 |
|
| 66 |
6. New IFirebirdAPI Calls: |
| 67 |
function HasLocalTZDB: boolean; |
| 68 |
function HasTimeZoneSupport: boolean; |
| 69 |
function HasExtendedTZSupport: boolean; |
| 70 |
procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte); |
| 71 |

| 72 |
|
| 73 |
7. New IAttachment Calls: |
| 74 |
function HasDecFloatSupport: boolean; |
| 75 |
function GetTimeZoneServices: ITimeZoneServices; |
| 76 |
function HasTimeZoneSupport: boolean; |
| 77 |
|
| 78 |
8. New Interface ITimeZoneServices. |
| 79 |
|
| 80 |
9. New ISQLData API Calls: |
| 81 |
procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload; |

function GetTransaction: ITransaction; |
| 97 |
procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload; |
| 98 |
procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload; |
| 99 |

| 101 |
procedure SetAsUTCDateTime(aUTCTime: TDateTime); |
| 102 |
procedure SetAsBcd(aValue: tBCD); |
| 103 |
|
| 104 |
11. New IArray API Calls |
| 105 |
procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload; |
| 106 |
procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload; |

| 109 |
function GetAsUTCDateTime(index: array of integer): TDateTime; |
| 110 |
procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload; |
| 111 |
procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload; |
| 112 |
procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload; |
| 113 |
procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload; |
| 114 |
|
| 115 |
12. Utility functions in IBUtils |
| 116 |
function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime; |
| 117 |
var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean; |
| 118 |
procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal); |
| 119 |

| 122 |
function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean; |
| 123 |
|
| 124 |
13. IDPB, ITPB and ISPB: new interface method |
| 125 |
function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem; |
| 126 |
This is used to add a parameter block item by the string equivalent of its |
| 127 |
symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...' |
| 128 |
|
| 129 |
14. IDPBItem/ITPBItem/ISPBItem: new interface method: |
| 130 |
function getParamTypeName: AnsiString; |
| 131 |
|
| 132 |
15. fb_shutdown now called before unloading Firebird library. This can avoid a |
| 133 |
SIGEVENT error when a programme using the embeded server is unloaded. |
| 134 |
|
| 135 |
FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100 |
| 136 |
|
| 137 |
1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API |
| 138 |
with a Firebrid 3 client library. |
| 139 |
|
| 140 |
2. Linux Only: FIREBIRD environment variable is now checked when loading the client library. |
| 141 |
If a client library path is not explicitly provided and the FIREBIRD environment |
| 142 |
variable is set then the directory given by this variable and any 'lib' subdirectory |
| 143 |
are searched for the Firebird client library. Only if none is found, is the default |
| 144 |
client library used. |
| 145 |
|
| 146 |
3. IUtil.FormatStatus now used to format error messages when using new API |
| 147 |
|
| 148 |
4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer. |
| 149 |
|
| 150 |
5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is |
| 151 |
returned using GetAsString and the string codepage is UTF8, the string is truncated so |
| 152 |
that the byte length corresponds to the number of characters specified for the column. |
| 153 |
SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is |
| 154 |
correct behaviour but may affect some implementations that relied upon automatic |
| 155 |
trimming of trailing white space. |
| 156 |
|
| 157 |
6. New IFirebirdAPI Calls: |
| 158 |
function GetClientMajor: integer; |
| 159 |
function GetClientMinor: integer; |
| 160 |
|
| 161 |
7. IColumnMetaData and IArrayMetaData: new method |
| 162 |
function GetCharSetWidth: integer; |
| 163 |
|
| 164 |
FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100 |
| 165 |
|
| 166 |
1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are |
| 167 |
case sensitive |
| 168 |
|
| 169 |
2. Single line SQL comments starting with '--' are now recognised by SQL Parser. |
| 170 |
|
| 171 |
3. New API Calls: |
| 172 |
IColumnMetaData.GetStatement |
| 173 |
IColumnMetaData.GetTransaction |
| 174 |
ISQLData.GetStrDataLength |
| 175 |
IResults.GetStatement |
| 176 |
IAttachment.OpenBlob (using Blob metadata) |
| 177 |
IAttachment.OpenArray (using array metadata) |
| 178 |
|
| 179 |
4. FBMessages: removal of unused messages |
| 180 |
|
| 181 |
5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set. |
| 182 |
|
| 183 |
6. TIBSQLStatementType: SQLSavePoint added to end of enumeration. |
| 184 |
|
| 185 |
FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000 |
| 186 |
|
| 187 |
1. Fix a problem with the SQL parameter parser that failed to recognise parameters |
| 188 |
where the second character of the parameter name is a numeric. |
| 189 |
|
| 190 |
2. New method for IAttachment: procedure getFBVersion(version: TStrings); |
| 191 |
This returns the isc_version connection information as one or more lines. |
| 192 |
This is the same information as returned by isql with the -z option. |
| 193 |
|
| 194 |
3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API |
| 195 |
is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a |
| 196 |
compiler option then the Firebird 3 API is no longer compiled in. |
| 197 |
|
| 198 |
4. IColumnMetaData: new method. |
| 199 |
|
| 200 |
TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP} |
| 201 |
dfDateTime, {SQL DATETIME} |
| 202 |
dfTime); |
| 203 |
|
| 204 |
function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer; |
| 205 |
|
| 206 |
This returns the max. number of characters returned by the "AsString" method |
| 207 |
when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME. |
| 208 |
|
| 209 |
5. Additional argument for IAttachment.PrepareWithNamedParameters - |
| 210 |
CaseSensitiveParams: boolean = false |
| 211 |
|
| 212 |
If this argument is set to true then SQL parameter names are assumed to be case |
| 213 |
sensitive and must be referenced (using ISQLParams.ByName) using the case |
| 214 |
sensitive name. |
| 215 |
|
| 216 |
6. Bug fix: when setting a query parameter, it is now possible, when the parameter |
| 217 |
is of type VarChar or Char to set the parameter to a numeric value (e.g. using |
| 218 |
.AsCurrency) and then subsequently to update the value to a non-numeric string |
| 219 |
using .AsString. |
| 220 |
|
| 221 |
|
| 222 |
|
| 223 |
FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000 |
| 224 |
|
| 225 |
1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary |
| 226 |
|
| 227 |
2. Restrict IsMultiThread check to Unix only for compatibility with |
| 228 |
https://bugs.freepascal.org/view.php?id=30535 |
| 229 |
|
| 230 |
3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with |
| 231 |
named parameters and is intended to avoid problems with (e.g.) Execute Block |
| 232 |
and processing internal parameters as statement parameters. |
| 233 |
|
| 234 |
4. New interface IFirebirdLibrary provides access to the underlying firebird DLL |
| 235 |
or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI. |
| 236 |
|
| 237 |
5. New function added to IB.pas |
| 238 |
|
| 239 |
function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary |
| 240 |
|
| 241 |
This allows a Firebird Library to be loaded from an explicit path. use the |
| 242 |
IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using |
| 243 |
the library. It is possible to load Firebird libraries from different locations |
| 244 |
simultaneously, each with a distinct IFirebirdAPI. |
| 245 |
|
| 246 |
FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100 |
| 247 |
|
| 248 |
1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when |
| 249 |
program compiled with -CR command line switch. |
| 250 |
|
| 251 |
2. IServiceManager additions (informational): |
| 252 |
function getProtocol: TProtocol; |
| 253 |
function getPortNo: AnsiString; |
| 254 |
|
| 255 |
3. IServiceManager improved error handling. Interfaces changed: |
| 256 |
function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean; |
| 257 |
function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; |
| 258 |
function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; |
| 259 |
|
| 260 |
4. IAttachment addition (informational) |
| 261 |
function GetSecurityDatabase: AnsiString; |
| 262 |
|
| 263 |
5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics |
| 264 |
thus now returns accumulated stats for a select statement from opening a cursor |
| 265 |
up to the last fetch. |
| 266 |
|
| 267 |
6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting |
| 268 |
the problem. |
| 269 |
|
| 270 |
7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64" |
| 271 |
replaces deprecated "comp" type. |
| 272 |
|
| 273 |
10. Testsuite Test10 updated to include thread synchronisation for event reporting. |
| 274 |
|
| 275 |
11. URL Connection Strings: inet4 and inet6 now recognised. |
| 276 |
|
| 277 |
12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax. |
| 278 |
|
| 279 |
13. IAttachment.CharSetName2CharSetID is now performed case insensitive. |
| 280 |
|
| 281 |
|
| 282 |
FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000 |
| 283 |
|
| 284 |
1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character. |
| 285 |
|
| 286 |
2. IAttachment: add two new methods |
| 287 |
function HasDefaultCharSet: boolean; |
| 288 |
function GetDefaultCharSetID: integer; |
| 289 |
|
| 290 |
These return, respectively, true if a connection default character set was |
| 291 |
specified and the character set id of the connection default character set. |
| 292 |
The DefaultCharSetID is cached when the connection is opened and hence does not |
| 293 |
require a database lookup. |
| 294 |
|
| 295 |
3. Avoid exception when a text blob is a stored procedure parameter. |
| 296 |
|
| 297 |
4. Update test suite to include a test for a stored proc returning a text blob. |
| 298 |
|
| 299 |
5. IAttachment: add |
| 300 |
function GetRemoteProtocol: AnsiString; |
| 301 |
function GetODSMajorVersion: integer; |
| 302 |
function GetODSMinorVersion: integer; |
| 303 |
function GetAuthenticationMethod: AnsiString; |
| 304 |
|
| 305 |
These results are cached when the connection is opened and hence do not |
| 306 |
require a database lookup. |
| 307 |
|
| 308 |
6. IAttachment: add "function GetConnectString: AnsiString;" This returns the |
| 309 |
connect string used to create/connect to the database. |
| 310 |
|
| 311 |
7. IAttachment: Create Database using SQL statement. The username and password |
| 312 |
are now extracted and used to populate a DPB made available via IAttachment.getDPB. |
| 313 |
It is now possible to use IAttachment disconnect/connect to reconnect to |
| 314 |
a database for which the initial connection was established by a create |
| 315 |
database sql statement. Available in FPC only. |
| 316 |
|
| 317 |
8. Update Test 1 to test 5, 6 and 7 above. |
| 318 |
|
| 319 |
9. IBUtils code tidy up. |
| 320 |
|
| 321 |
10. Parameter Block interfaces "find" method. As documented, this should have |
| 322 |
returned a nil interface when the item could not be found. Instead, an empty |
| 323 |
interface item was returned. "Find" now works as documented and will return |
| 324 |
a nil interface if the item cannot be found. |
| 325 |
|
| 326 |
11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date. |
| 327 |
|
| 328 |
12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information |
| 329 |
requests with additional parameters. This is to enable support for fb_info_page_contents |
| 330 |
(return of page contents). Response to fb_info_page_contents returned as |
| 331 |
a string with code page CP_NONE. |
| 332 |
|
| 333 |
13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus |
| 334 |
test suite updated. |
| 335 |
|
| 336 |
14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as |
| 337 |
a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type. |
| 338 |
|
| 339 |
15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet. |
| 340 |
An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non |
| 341 |
default connection port to be specified. |
| 342 |
|
| 343 |
FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000 |
| 344 |
|
| 345 |
1. Fix issues with setting SQL Param values using SetAsString with Numeric types. |
| 346 |
Scale is no longer ignored. |
| 347 |
|
| 348 |
2. Fix issues with setting SQL Param values using SetAsString with Date values |
| 349 |
not in locale format but which are recognised by Firebird. Date values that |
| 350 |
cannot be converted to a string using Pascal library are now passed through |
| 351 |
to Firebird as Text Strings. |
| 352 |
|
| 353 |
3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns |
| 354 |
UTF8 and not UNICODE_FSS. |
| 355 |
|
| 356 |
4. Charset ID problem. When using Firebird 3, with no default database character set |
| 357 |
and a column has a non-default collation specified, an incorrect character set |
| 358 |
id was being reported that could result in a 'division by zero' error when |
| 359 |
used by IBX. This has now been fixed. |
| 360 |

5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID, |
| 362 |
CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as |
| 363 |
the character sets supported can be updated on a per database basis. That is |
| 364 |
it is possible to add a (Firebird) user defined character set to a database. |
| 365 |
|
| 366 |
6. Add RegisterCharSet to IAttachment. This is used to register a user defined character |
| 367 |
set supported by Firebird with the API. |
| 368 |
|
| 369 |
7. Add missing isc_info_db_read_only to list of decoded Database Information items |
| 370 |
in FBOutputBlock.pas and update test suite to include this item. |
| 371 |
|
| 372 |
8. FB30Client: avoid always using "StartMultiple" when only a single database attachment. |
| 373 |
|
| 374 |
9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client |
| 375 |
library or finding it by disk location, the PATH environment variable is now also set to |
| 376 |
include the FIREBIRD directory. This is to ensure that the correct dlls in the |
| 377 |
firebird client library dependencies are loaded. |
| 378 |
|
| 379 |
10. Testsuite: Ensure consistent UTF-8 output on Windows console. |
| 380 |
|
| 381 |
11. Testsuite: Update Windows script to include FPC 3.0.4 in search path. |
| 382 |
|
| 383 |
12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer |
| 384 |
|
| 385 |
13. FB30Statement: A check has been added to ensure that all SQL Parameters |
| 386 |
have been given a value (including NULL). Previously, failing to set the |
| 387 |
value of an SQL Parameter could give rise to unpredictable results or |
| 388 |
an SQLDA error. |
| 389 |
|
| 390 |
14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set. |
| 391 |
|
| 392 |
15. FBAttachment: Avoid string reference count error when processing an Ansistring |
| 393 |
parameter in an array of const passed to IAttachment.OpenCursor, etc. |
| 394 |
|
| 395 |
16. FBAttachment: Allow for WideString and UnicodeString parameters in an array |
| 396 |
of const passed to IAttachment.OpenCursor, etc. |
| 397 |

| 400 |
|
| 401 |
1. Change syntax to Mode Delphi |
| 402 |
|
| 403 |
2. Change all uses of string type to explicit AnsiString in order to ensure |
| 404 |
compatibility between Delphi and FPC. |
| 405 |
|
| 406 |
3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs |
| 407 |
defined for each interface. |
| 408 |
|
| 409 |
4. Generics syntax variations for Delphi added |
| 410 |
|
| 411 |
5. PChar replaced with PByte expect where an actual string is being referenced, |
| 412 |
where PAnsiChar is used instead. |
| 413 |
|
| 414 |
6. Review of type definitions in IBExternals to ensure Delphi compatibility |
| 415 |
|
| 416 |
7. Testsuite updated for Delphi |
| 417 |
|
| 418 |
FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000 |
| 419 |
|
| 420 |
1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with |
| 421 |
large blobs and the FB3 API. |
| 422 |
|
| 423 |
2. Update Event Handling algorithm to avoid looping due to recreation of the |
| 424 |
event block. |
| 425 |
|
| 426 |
3. Avoid invalid XSQLDA error when the only parameter is updated to null |
| 427 |
|
| 428 |
4. Array Handling: fix problem with text arrays with character set none. When the |
| 429 |
DB connection has a default character set (e.g. UTF8), an error is raised by |
| 430 |
Firebird if the space allocated is not enough to allow for transliteration, even |
| 431 |
though it is not required for character set none. |
| 432 |
|
| 433 |
5. IBUtils: List of reserved words brought up-to-date |
| 434 |
|
| 435 |
6. Add ISQL style performance statistics collection to IStatement |
| 436 |
|
| 437 |
7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided |
| 438 |
CREATE DATABASE statement. |
| 439 |
|
| 440 |
8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in |
| 441 |
an array dimension is not mistaken for a named parameter prefix. |
| 442 |
|
| 443 |
9. Trim function no longer applied to result of GetAsString for SQL_TEXT |
| 444 |
when Character set is octets. Avoids loss of non printable characters at start of string. |
| 445 |
|
| 446 |
10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance |
| 447 |
statistics for the last action. Requires use of procedure IStatement.EnableStatistics |
| 448 |
to enable stats gathering. |
| 449 |
|
| 450 |
11. API Version information added as constants to IB.pas |
| 451 |
|
| 452 |
12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID |
| 453 |
|
| 454 |
13. Firebird Character set "NONE" now interpreted as codepage CP_ACP. |
| 455 |
