Release Notes for the GM - Firebird and InterBase ODBC Driver

Version 1.4.0 released, 11. Mar 2006

• Transactions started using isc_start_multiple instead of isc_start_transaction now. The va_arg list of isc_start_transaction sometimes caused access violations.
• Database connections to a local server on Win2000 work now.
• Connect/disconnect to/from local server is much faster now.
• SQLSpecialColumns, SQLStatistics and SQLDescribeParam implemented now.
• Works with MS-Query now. Updating data from MS-Query doesn't work.
• MS-Access can link tables now but thinks all rows are deleted when showing the data.
• ADO OLE-DB provider for ODBC works fine with the driver.
• Setup now build with NSIS.
• InterBase client installation included in the setup now.
• Complete source code included in the setup now.
• Some internal simplifications.

Version 1.3.5 released, 02. May 2004

• Errors intoduced by latest changes fixed.

Version 1.3.4 released, 26. Apr 2004

• More data type conversions supported by the driver now.
• Aggregate select functions MIN, MAX, AVG, SUM, COUNT give correct result set when executed on other cursors than SQL_CURSOR_FORWARD_ONLY.
• String input parameters are always correctly converted to InterBase now.
• If application buffers are too small the driver allocates its own buffers and translates data to application buffers now.
• Some internal simplifications done.

Version 1.3.1 released, 13. Apr 2004

• Installation option for InterBase client driver added to Setup.

Version 1.3 released, 04. Dec 2003

• SQLGetTYpeInfo Implemented now.
• SQLFreeXxxx / SQLAllocXxxx implemented again to support ODBC 2.0 applications.
• SQLGetData can be used even if there are no buffers bound by the application. Still the driver does not allocate own buffers if the application provides buffers via SQLBindCol.
• Parameters are supported now via SQLBindParameter or SQLParamData + SQLPutData.
• All data can be delivered as SQL_C_CHAR by the driver now (via SQLGetData and SQLBindCol). The driver will deliver a textual representation of the data in this case.
• All options for SQLFreeStmt implemnted now. This allows cursor reuse.
• Implementation of SQLTables now is sensitive to SQL_ATTR_METADATA_ID.

Version 1.2.1 released, 14. Nov 2003

• Additional attributes supported by SQLGetInfo now.
• Registry value names changed. Existing DSN entries need to be recreated or edited once. The old settings of existing DSN entries will be forgotten.
• SQLDriverConnect parses the whole Connection String now. Values read by "DSN=XXX" are superseded by the values given in the connection string. The token "DSN=XXX" maybe omitted completely, but then the values given in the connection string should privde enough information for a successful connection. possible values are:
  BlobWriteSegmentSize=16384
  CacheBuffers=75
  CharsetName=ISO8859_1 (ASCII, BIG_5, CYRL, DOS437, DOS850, DOS852, DOS857, DOS860, DOS861, DOS863, DOS865, EUCJ_0208, GB_2312, ISO8859_1, KSC_5601, NEXT, NONE, OCTETS, SJIS_0208, UNICODE_FSS, WIN1250, WIN1251, WIN1252, WIN1253, WIN1254)
  DBFilePath=\database\myDatabase.gdb

  GeneratorMatchFmtStr=%s_%s
  License=XXXXX
  LockGranularity=0 (lgRow = 0, lgTable = 1)
  LockResolution=0 (lrWait = 0, lrFail = 1)
  PWD=masterkey
  RoleName=XXXXX
  ServerPath=DBSERVER
  SQLDialect=3 (V5 = 1, V5/V6 = 2, V6 = 3)
  SysUsername=SYSDBA

  WriteStrategy=0 (wsAllowAsyncWrites = 0, wsForceSyncWrites = 1)

Version 1.2 released, 11. Jul 2003

• More ODBC attributes supported now.
• Browsing ADO client side cursors through the driver works now.
• Safe against invalid handles passed to the driver now.
• Uneccessary functions dropped from the driver.
• Bind offsets recognized by the driver now.
• Workaround for InterBase access violation with transactions on local server included.

• Update of multi table queries possible.
• Lean but effective implementation results in high performance.
• Clear and understandable DSN setup dialog.
• Automatic increment of integer ID fields possible.
• Tested with InterBase 6.0/6.5.
