 Question and Answer Database

     FAQ: FAQ4565B - MSSQL 7 SQL Links (v5.01.23) feature support, MS DBLIB (NTWDBLIB.DLL)
Category: Database (MSSQL)
Platform: All-32Bit
 Product: All-CBuilder,   C++Builder1.0,   C++Builder3.x,   C++Builder4.x,   Delphi2.x,   Delphi3.x,   Delphi4.x,   VdBase7.x,   

Question:

Why aren't all of the new features and types supported 
in the new version of the MSSQL SQL Links driver?


Answer:

Please see the BDEREADME.TXT for additional information regarding
BDE and SQL Links v5.01.

New MS-SQL Server 7 Driver
--------------------------
The SQL Links (not available with all editions of Inprise
programming tools) driver for Microsoft SQL Server now
supports version 7, in addition to support in the same
driver for version 6.5.

SQL Links uses DBLIB (native API for MS-SQL Server).
DBLIB only implements the MS-SQL Server 6.5 feature set.
This means that new types in MS-SQL Server 7 like GUID,
Unicode, and CHAR columns longer than 255 characters are
not supported. Microsoft will not be adding support for
these new types to DBLIB, so the SQL Links driver does not
support these new MS-SQL Server 7 types.

Both Microsoft and Inprise strongly recommend that you use
the client software appropriate for the version of MS-SQL
Server used. That is, use version 6.x client software only
with 6.x server software and version 7 client software only
with version 7 server software.
