1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit. |
| 4 |
> |
|
| 5 |
> |
2. Remove constraint in IAttachment.HasScollableCursors that returned false when |
| 6 |
> |
using remote protocol. Scrollable cursors with remote database expected to |
| 7 |
> |
be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return |
| 8 |
> |
a not supported error. |
| 9 |

|

3. IStatement: new function; |
| 11 |
> |
TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable); |
| 12 |
> |
TStatementFlags = set of TStatementFlag; |
| 13 |
> |
function GetFlags: TStatementFlags; |
| 14 |
> |
|
| 15 |

4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards |
| 16 |
> |
compatibility. |
| 17 |
> |
In Firebird 5, Update..Returning may returns multiple rows and hence the statemen |
| 18 |
> |
type changes from ExecProcedure to Select. So that ExecuteQuery can continue |
| 19 |
> |
to be used with Update...Retruning statements that return a singleton row, |
| 20 |
> |
instead of raising an exception when ExecuteQuery is used with a (SELECT) statement, |
| 21 |
> |
it will open the cursor and return the first row only. |
| 22 |
> |
|
| 23 |
> |
5. ITransaction: new functions: |
| 24 |
> |
function GetIsReadOnly: boolean; |
| 25 |
> |
function GetTransactionID: integer; |
| 26 |
> |
function GetTrInformation(Requests: array of byte): ITrInformation; overload; |
| 27 |
> |
function GetTrInformation(Request: byte): ITrInformation; overload; |
| 28 |
> |
|
| 29 |
> |
The latter two return the Transaction Information block. The first two extract |
| 30 |
> |
information the Transaction Information block |
| 31 |
> |
|
| 32 |
> |
6. New function TSQLTokeniser.ReadCharacters |
| 33 |
> |
Used internally. |
| 34 |
> |
|
| 35 |
> |
7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains |
| 36 |
> |
parameter placeholders instead of named parameters. |
| 37 |
> |
|
| 38 |
> |
8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying |
| 39 |
> |
transaction handle is now ignored if Rollback/Commit is called with Force=true |

|
1. TFBClientAPI.GetProcAddr. Add check for nil reference. |
| 44 |
|
|
| 50 |
|
user to disable them on a per statement basis. Note this can risk out-of-date |
| 51 |
|
statement BLR. See User Guide. |
| 52 |
|
|
| 53 |
+ |
3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a |
| 54 |
+ |
stored procedure and hence avoids replacing named parameters within a containing |
| 55 |
+ |
BEGIN..END block. |
| 56 |
+ |
|
| 57 |
+ |
4. ISQLParam: using a string value to set an integer field with a scale factor of |
| 58 |
+ |
zero is now treated as a special case to avoid the risk of floating point |
| 59 |
+ |
rounding errors affecting pure integers. |
| 60 |
+ |
|
| 61 |
+ |
5. ISQLParam: Review and tidy-up of SetAsString for numeric types. |
| 62 |
+ |
|
| 63 |
+ |
6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable |
| 64 |
+ |
SQL Parameter metadata (methods moved from ISQLParam). |
| 65 |
+ |
|
| 66 |
+ |
7. ISQLParam: new method |
| 67 |
+ |
function getColMetadata: IParamMetaData; |
| 68 |
+ |
This instance of IParamMetaData returns the original column metadata which is unmutable. |
| 69 |
+ |
Note: ISQLParam metadata can change after a parameter value has been set e.g when |
| 70 |
+ |
setting a VARCHAR column to an integer value. |
| 71 |
+ |
|
| 72 |
+ |
8. IStatement: can now set cursor name when opening a cursor. New overloaded method: |
| 73 |
+ |
procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload; |
| 74 |
+ |
also IAttachment: |
| 75 |
+ |
function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload; |
| 76 |
+ |
function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload; |
| 77 |
+ |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 78 |
+ |
aSQLDialect: integer; GenerateParamNames: boolean=false; |
| 79 |
+ |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 80 |
+ |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 81 |
+ |
GenerateParamNames: boolean=false; |
| 82 |
+ |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 83 |
+ |
|
| 84 |
+ |
9. Support for scrollable cursors added. New/updated methods: |
| 85 |
+ |
IAttachment: |
| 86 |
+ |
function HasScollableCursors: boolean; |
| 87 |
+ |
function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; |
| 88 |
+ |
Scrollable: boolean=false): IResultSet; overload; |
| 89 |
+ |
function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 90 |
+ |
function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean; |
| 91 |
+ |
params: array of const): IResultSet; overload; |
| 92 |
+ |
function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false; |
| 93 |
+ |
params: array of const): IResultSet; overload; |
| 94 |
+ |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean; |
| 95 |
+ |
params: array of const): IResultSet; overload; |
| 96 |
+ |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; |
| 97 |
+ |
Scrollable: boolean=false): IResultSet; overload; |
| 98 |
+ |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 99 |
+ |
function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean; |
| 100 |
+ |
params: array of const): IResultSet; overload; |
| 101 |
+ |
function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; |
| 102 |
+ |
function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean; |
| 103 |
+ |
params: array of const): IResultSet; overload; |
| 104 |
+ |
IStatement: |
| 105 |
+ |
function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload; |
| 106 |
+ |
IResultSet: |
| 107 |
+ |
function FetchPrior: boolean; {fetch previous record} |
| 108 |
+ |
function FetchFirst:boolean; {fetch first record} |
| 109 |
+ |
function FetchLast: boolean; {fetch last record} |
| 110 |
+ |
function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set} |
| 111 |
+ |
function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current} |
| 112 |
+ |
function IsBof: boolean; |
| 113 |
+ |
|
| 114 |
+ |
10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers. |
| 115 |
+ |
|
| 116 |
+ |
11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This |
| 117 |
+ |
may be noticeable when a line separator occurs inside quoted text. The quoted text |
| 118 |
+ |
output by the tokeniser will now use the platform specific lineEnding regardless |
| 119 |
+ |
of whether the input uses the CRLF or LF as a line separator. |
| 120 |
+ |
|
| 121 |
+ |
12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only) |
| 122 |
+ |
|
| 123 |
+ |
|

|
1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers. |
