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. |

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. |

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 |

procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte); |

function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD; |

> |
function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem; |
| 126 |

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 |

7. IColumnMetaData and IArrayMetaData: new method |

function GetCharSetWidth: integer; |

1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are |

case sensitive |

|
|
| 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. |
| 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 |
+ |
