> |
1. TFBClientAPI.GetProcAddr. Add check for nil reference. |
| 4 |
> |
|
| 5 |
> |
2. IStatement: new methods: |
| 6 |
> |
procedure SetStaleReferenceChecks(Enable:boolean); {default true} |
| 7 |
> |
function GetStaleReferenceChecks: boolean; |
| 8 |
> |
|
| 9 |
> |
In previous versions, stale reference checks were always enabled. This allows the |
| 10 |
> |
user to disable them on a per statement basis. Note this can risk out-of-date |
| 11 |
> |
statement BLR. See User Guide. |
| 12 |
> |
|
| 13 |
> |
3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a |
| 14 |
> |
stored procedure and hence avoids replacing named parameters within a containing |
| 15 |
> |
BEGIN..END block. |
| 16 |
> |
|
| 17 |
> |
4. ISQLParam: using a string value to set an integer field with a scale factor of |
| 18 |
> |
zero is now treated as a special case to avoid the risk of floating point |
| 19 |
> |
rounding errors affecting pure integers. |
| 20 |
> |
|
| 21 |
> |
5. ISQLParam: Review and tidy-up of SetAsString for numeric types. |
| 22 |
> |
|
| 23 |
> |
6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable |
| 24 |
> |
SQL Parameter metadata (methods moved from ISQLParam). |
| 25 |
> |
|
| 26 |
> |
7. ISQLParam: new method |
| 27 |
> |
function getColMetadata: IParamMetaData; |
| 28 |
> |
This instance of IParamMetaData returns the original column metadata which is unmutable. |
| 29 |
> |
Note: ISQLParam metadata can change after a parameter value has been set e.g when |
| 30 |
> |
setting a VARCHAR column to an integer value. |
| 31 |
> |
|
| 32 |
> |
8. IStatement: can now set cursor name when opening a cursor. New overloaded method: |
| 33 |
> |
procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload; |
| 34 |
> |
also IAttachment: |
| 35 |
> |
function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload; |
| 36 |
> |
function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload; |
| 37 |
> |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 38 |
> |
aSQLDialect: integer; GenerateParamNames: boolean=false; |
| 39 |
> |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 40 |
> |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 41 |
> |
GenerateParamNames: boolean=false; |
| 42 |
> |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 43 |
> |
|
| 44 |
> |
9. Support for scrollable cursors added. New/updated methods: |
| 45 |
> |
IAttachment: |
| 46 |
> |
function HasScollableCursors: boolean; |
| 47 |
> |
function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; |
| 48 |
> |
Scrollable: boolean=false): IResultSet; overload; |
| 49 |
> |
function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 50 |
> |
function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean; |
| 51 |
> |
params: array of const): IResultSet; overload; |
| 52 |
> |
function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false; |
| 53 |
> |
params: array of const): IResultSet; overload; |
| 54 |
> |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean; |
| 55 |
> |
params: array of const): IResultSet; overload; |
| 56 |
> |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; |
| 57 |
> |
Scrollable: boolean=false): IResultSet; overload; |
| 58 |
> |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 59 |
> |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean; |
| 60 |
> |
params: array of const): IResultSet; overload; |
| 61 |
> |
function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 62 |
> |
function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean; |
| 63 |
> |
params: array of const): IResultSet; overload; |
| 64 |
> |
IStatement: |
| 65 |
> |
function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload; |
| 66 |
> |
IResultSet: |
| 67 |
> |
function FetchPrior: boolean; {fetch previous record} |
| 68 |
> |
function FetchFirst:boolean; {fetch first record} |
| 69 |
> |
function FetchLast: boolean; {fetch last record} |
| 70 |
> |
function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set} |
| 71 |
> |
function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current} |
| 72 |
> |
function IsBof: boolean; |
| 73 |
> |
|
| 74 |
> |
10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers. |
| 75 |
> |
|
| 76 |
> |
11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This |
| 77 |
> |
may be noticeable when a line separator occurs inside quoted text. The quoted text |
| 78 |
> |
output by the tokeniser will now use the platform specific lineEnding regardless |
| 79 |
> |
of whether the input uses the CRLF or LF as a line separator. |
| 80 |
> |
|
| 81 |
> |
12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only) |
| 82 |

1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers. |
| 87 |
> |
|
| 88 |
> |
2. Support for inline blob encoding. Blob values pass using the "SetAsString" method |
| 89 |
> |
will now be encoded inline (i.e. as part of the parameter buffer) if they are |
| 90 |
> |
shorter than a pre-set limit. Longer values continue to be saved as blobs as a |
| 91 |
> |
separate server interaction. This is intended as a performance optimisation. |
| 92 |
> |
|
| 93 |
> |
The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new |
| 94 |
> |
IAttachment interface functions: |
| 95 |
> |
|
| 96 |
> |
function GetInlineBlobLimit: integer; |
| 97 |
> |
procedure SetInlineBlobLimit(limit: integer); |
| 98 |
> |
|
| 99 |
> |
3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API |
| 100 |
> |
user as the functionality is embedded in the implementation of the IStatement |
| 101 |
> |
interface. Three new functions are defined: |
| 102 |
> |
|
| 103 |
> |
procedure AddToBatch; |
| 104 |
> |
function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion; |
| 105 |
> |
procedure CancelBatch; |
| 106 |
> |
function GetBatchCompletion: IBatchCompletion; |
| 107 |
> |
function GetBatchRowLimit: integer; |
| 108 |
> |
procedure SetBatchRowLimit(aLimit: integer); |
| 109 |
> |
|
| 110 |
> |
Also |
| 111 |
> |
|
| 112 |
> |
function IsInBatchMode: boolean; {true after call to execute(eaDefer)} |
| 113 |
> |
function HasBatchMode: boolean; {true if and only if IBatch Supported} |
| 114 |
> |
|
| 115 |
> |
For more information see the User Guide. |
| 116 |
> |
|
| 117 |
> |
4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages |
| 118 |
> |
provided with the EIBInterBaseError now include all three parts. |
| 119 |
> |
|
| 120 |
> |
5. Firebird.pas and include files updated to Firebird 4.0.0 |
| 121 |
> |
|
| 122 |
> |
6. New IStatement method: function GetSQLStatementTypeName: AnsiString; |
| 123 |
> |
Returns SQL Statement type as a text string; |
| 124 |
> |
|
| 125 |
> |
7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to |
| 126 |
> |
an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger. |
| 127 |
> |

1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a |
| 131 |
> |
typo in FB30Statement.pas that caused an unknown parameter error. |
| 132 |

1. Imported (Firebird) constants updated for Firebird 4. |
| 136 |
> |
|
| 137 |
> |
2. Firebird.pas from Firebird 4 integrated into source code tree. |
| 138 |
> |
|
| 139 |
> |
3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types. |
| 140 |
> |
|
| 141 |
> |
4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision. |
| 142 |
> |
|
| 143 |
> |
5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider. |
| 144 |
> |
QueryInterface may be used to coerce this interface from IFirebirdAPI. The |
| 145 |
> |
interface provides a single method "function GetIMasterIntf: IMaster". This provides |
| 146 |
> |
type safe access to the Firebird IMaster interface and avoids the need to turn |
| 147 |
> |
off object checks when coercing "function GetIMaster: TObject" to IMaster. |
| 148 |
> |
|
| 149 |
> |

1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API |
| 221 |
> |
with a Firebrid 3 client library. |
| 222 |
> |
|
| 223 |
> |
2. Linux Only: FIREBIRD environment variable is now checked when loading the client library. |
| 224 |
> |
If a client library path is not explicitly provided and the FIREBIRD environment |
| 225 |
> |
variable is set then the directory given by this variable and any 'lib' subdirectory |
| 226 |
> |
are searched for the Firebird client library. Only if none is found, is the default |
| 227 |
> |
client library used. |
| 228 |
> |
|
| 229 |
> |
3. IUtil.FormatStatus now used to format error messages when using new API |
| 230 |
> |
|
| 231 |
> |
4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer. |
| 232 |
> |
|
| 233 |
> |
5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is |
| 234 |
> |
returned using GetAsString and the string codepage is UTF8, the string is truncated so |
| 235 |
> |
that the byte length corresponds to the number of characters specified for the column. |
| 236 |
> |
SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is |
| 237 |
> |
correct behaviour but may affect some implementations that relied upon automatic |
| 238 |
> |
trimming of trailing white space. |
| 239 |
