| 53 |
> |
will be allocted for batch operations. |
| 54 |
> |
|
| 55 |
> |
6. IStatement, IColumnMetaData and ISQLParam all now consistently provide: |
| 56 |
> |
function GetStatement: IStatement; |
| 57 |
> |
function GetTransaction: ITransaction; |
| 58 |
> |
function GetAttachment: IAttachment; |
| 59 |

7. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted |
| 61 |
> |
interfaces. |
| 62 |
> |
|
| 63 |
> |
8. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric |
| 64 |
> |
and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam |
| 65 |
> |
functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation |
| 66 |
> |
of numerics without loss of precision. |
| 67 |
> |
|
| 68 |
> |
9. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric. |
| 69 |
> |
|
| 70 |
> |
10. ISQLParams new method "Clear" |
| 71 |
> |
|
| 72 |
> |
11. Support package fbudr added for support of User Defined Routines (UDRs). |
| 73 |
> |
|
| 74 |
> |
12. Package layout changed with introduction of udr support. IB*.pas files moved from |
| 75 |
> |
root directory to "client". IBHeader move to "Client". |
| 76 |

|
| 77 |
> |
13. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first |
| 78 |

1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit. |
| 84 |
> |
|
| 85 |
> |
2. Remove constraint in IAttachment.HasScollableCursors that returned false when |
| 86 |
> |
using remote protocol. Scrollable cursors with remote database expected to |
| 87 |
> |
be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return |
| 88 |
> |
a not supported error. |
| 89 |
> |
|
| 90 |
> |
3. IStatement: new function; |
| 91 |
> |
TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable); |
| 92 |
> |
TStatementFlags = set of TStatementFlag; |
| 93 |
> |
function GetFlags: TStatementFlags; |
| 94 |
> |
|
| 95 |
> |
4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards |
| 96 |
> |
compatibility. |
| 97 |
> |
In Firebird 5, Update..Returning may returns multiple rows and hence the statemen |
| 98 |
> |
type changes from ExecProcedure to Select. So that ExecuteQuery can continue |
| 99 |
> |
to be used with Update...Retruning statements that return a singleton row, |
| 100 |
> |
instead of raising an exception when ExecuteQuery is used with a (SELECT) statement, |
| 101 |
> |
it will open the cursor and return the first row only. |
| 102 |
> |
|
| 103 |
> |
5. ITransaction: new functions: |
| 104 |
> |
function GetIsReadOnly: boolean; |
| 105 |
> |
function GetTransactionID: integer; |
| 106 |
> |
function GetTrInformation(Requests: array of byte): ITrInformation; overload; |
| 107 |
> |
function GetTrInformation(Request: byte): ITrInformation; overload; |
| 108 |
> |
|
| 109 |
> |
The latter two return the Transaction Information block. The first two extract |
| 110 |
> |
information the Transaction Information block |
| 111 |
> |
|
| 112 |
> |
6. New function TSQLTokeniser.ReadCharacters |
| 113 |
> |
Used internally. |
| 114 |
> |
|
| 115 |
> |
7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains |
| 116 |
> |
parameter placeholders instead of named parameters. |
| 117 |
> |
|
| 118 |
> |
8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying |
| 119 |
> |
transaction handle is now ignored if Rollback/Commit is called with Force=true |
| 120 |
> |
|
| 121 |
> |
9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now |
| 122 |
> |
used to get an IBError Message instead of isc_interprete. |
| 123 |
> |
|
| 124 |
> |
10. Internal tidyup. Native code now used for decoding integers and the events |
| 125 |
> |
buffer. Avoids dependencies on fbclient functions isc_portable_integer, |
| 126 |
> |
isc_event_block and isc_event_counts. |
| 127 |
> |
|
| 128 |
> |
11. New IAttachment function |
| 129 |
> |
function GetAttachmentID: integer; |
| 130 |
> |
|
| 131 |
> |
12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30 |
| 132 |
> |
subclasses to enable UDR support. |
| 133 |
> |

|
| 136 |
> |
1. TFBClientAPI.GetProcAddr. Add check for nil reference. |
| 137 |
> |
|
| 138 |
> |
2. IStatement: new methods: |
| 139 |
> |
procedure SetStaleReferenceChecks(Enable:boolean); {default true} |
| 140 |
> |
function GetStaleReferenceChecks: boolean; |
| 141 |
> |
|
| 142 |
> |
In previous versions, stale reference checks were always enabled. This allows the |
| 143 |
> |
user to disable them on a per statement basis. Note this can risk out-of-date |
| 144 |
> |
statement BLR. See User Guide. |
| 145 |
> |
|
| 146 |
> |
3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a |
| 147 |
> |
stored procedure and hence avoids replacing named parameters within a containing |
| 148 |
> |
BEGIN..END block. |
| 149 |
> |
|
| 150 |
> |
4. ISQLParam: using a string value to set an integer field with a scale factor of |
| 151 |
> |
zero is now treated as a special case to avoid the risk of floating point |
| 152 |
> |
rounding errors affecting pure integers. |
| 153 |
> |
|
| 154 |
> |
5. ISQLParam: Review and tidy-up of SetAsString for numeric types. |
| 155 |
> |
|
| 156 |
> |
6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable |
| 157 |
> |
SQL Parameter metadata (methods moved from ISQLParam). |
| 158 |
> |
|
| 159 |
> |
7. ISQLParam: new method |
| 160 |
> |
function getColMetadata: IParamMetaData; |
| 161 |
> |
This instance of IParamMetaData returns the original column metadata which is unmutable. |
| 162 |
> |
Note: ISQLParam metadata can change after a parameter value has been set e.g when |
| 163 |
> |
setting a VARCHAR column to an integer value. |
| 164 |
> |
|
| 165 |
> |
8. IStatement: can now set cursor name when opening a cursor. New overloaded method: |
| 166 |
> |
procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload; |
| 167 |
> |
also IAttachment: |
| 168 |
> |
function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload; |
| 169 |
> |
function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload; |
| 170 |
> |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 171 |
> |
aSQLDialect: integer; GenerateParamNames: boolean=false; |
| 172 |
> |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 173 |
> |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 174 |
> |
GenerateParamNames: boolean=false; |
| 175 |
> |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 176 |
> |
|
| 177 |
> |
9. Support for scrollable cursors added. New/updated methods: |
| 178 |
> |
IAttachment: |
| 179 |
> |
function HasScollableCursors: boolean; |
| 180 |
> |
function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; |
| 181 |
> |
Scrollable: boolean=false): IResultSet; overload; |
| 182 |
> |
function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 183 |
> |
function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean; |
| 184 |

Scrollable: boolean=false): IResultSet; overload; |
| 191 |
> |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 192 |
> |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean; |
| 193 |
> |
params: array of const): IResultSet; overload; |
| 194 |
> |
function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 195 |
> |
function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean; |
| 196 |
> |
params: array of const): IResultSet; overload; |
| 197 |
> |
IStatement: |
| 198 |
> |
function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload; |
| 199 |
> |
IResultSet: |
| 200 |

function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current} |
| 205 |
> |
function IsBof: boolean; |
| 206 |
> |
|
| 207 |
> |
10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers. |
| 208 |
> |
|
| 209 |
> |
11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This |
| 210 |
> |
may be noticeable when a line separator occurs inside quoted text. The quoted text |
| 211 |
> |
output by the tokeniser will now use the platform specific lineEnding regardless |
| 212 |
> |
of whether the input uses the CRLF or LF as a line separator. |
| 213 |
> |
|
| 214 |
> |
12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only) |

1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers. |
| 220 |
> |
|
| 221 |
> |
2. Support for inline blob encoding. Blob values pass using the "SetAsString" method |
| 222 |
> |
will now be encoded inline (i.e. as part of the parameter buffer) if they are |
| 223 |
> |
shorter than a pre-set limit. Longer values continue to be saved as blobs as a |
| 224 |
> |
separate server interaction. This is intended as a performance optimisation. |
| 225 |
> |
|
| 226 |
> |
The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new |
| 227 |
> |
IAttachment interface functions: |
| 228 |
> |
|
| 229 |
> |
function GetInlineBlobLimit: integer; |
| 230 |
> |
procedure SetInlineBlobLimit(limit: integer); |
| 231 |
> |
|
| 232 |
> |
3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API |
| 233 |
> |
user as the functionality is embedded in the implementation of the IStatement |
| 234 |
> |
interface. Three new functions are defined: |
| 235 |
> |
|
| 236 |
> |
procedure AddToBatch; |
| 237 |
> |
function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion; |
| 238 |
> |
procedure CancelBatch; |
| 239 |
> |
function GetBatchCompletion: IBatchCompletion; |
| 240 |
> |
function GetBatchRowLimit: integer; |
| 241 |
> |
procedure SetBatchRowLimit(aLimit: integer); |
| 242 |
> |
|
| 243 |
> |
Also |
| 244 |
> |
|
| 245 |
> |
function IsInBatchMode: boolean; {true after call to execute(eaDefer)} |
| 246 |
> |
function HasBatchMode: boolean; {true if and only if IBatch Supported} |
| 247 |
> |
|
| 248 |
> |
For more information see the User Guide. |
| 249 |
> |
|
| 250 |
> |
4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages |
| 251 |
> |
provided with the EIBInterBaseError now include all three parts. |
| 252 |
> |
|
| 253 |
> |
5. Firebird.pas and include files updated to Firebird 4.0.0 |
| 254 |
> |
|
| 255 |
> |
6. New IStatement method: function GetSQLStatementTypeName: AnsiString; |
| 256 |
> |
Returns SQL Statement type as a text string; |
| 257 |
> |
|
| 258 |
> |
7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to |
| 259 |
> |
an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger. |

|
|
| 263 |
|
1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a |
| 264 |
|
typo in FB30Statement.pas that caused an unknown parameter error. |
