Migration from BDE

In SDAC the interests of BDE application developers were taken into consideration. So starting to use SDAC after working with BDE would be easy even for developing complex projects. Moreover, SDAC does not have problems like ones with LiveQuery and compatibility of applications developed using different versions in BDE. On SDAC developing BDE users interests were taken in consideration so conversion from using BDE into SDAC can be passed without difficulties even for complex projects. Moreover, SDAC does not have problems appropriated BDE with LiveQuery and compatibility of different programs that were developed using different BDE version and so on.

Abandoning BDE gives one more important advantage - positive effect on performance. Instead of complex BDE-ODBC drivers system it uses the fastest access - directly to Microsoft SQL Server.

SDAC provides special Wizard to simplify the conversion of already existing projects. This Wizard replaces BDE-components in the specified project (dfm-and pas-files) to SDAC. BDE-components that will be replaced:

To run the Wizard select BDE/ADO Migration Wizard item in SDAC menu and follow the instructions. This Wizard is available only for Delphi IDE.

Note: Wizard serves only to simplify routine operations and after the conversion project might be uncompiled.

Below is a list of properties and methods that cannot be converted automatically. Here you can find hints for users to simplify manual replacement.







SDAC does not need global management of a group of database connections in an application.


A complete analogue to TMSUpdateSQL.
