What causes BDE Error 8712 "Could not find object" when accessing MS SQL Server 7 table? Other Symptoms could be columns not appearing or blank.


MS SQL Server 7 introduces new field types called NVARCHAR, NCHAR and NTEXT. These types represent Unicode data and are not supported by the BDE.

The workaround is to change these field types to VARCHAR or TEXT.

Please note there are no ODBC drivers which have been certified by Borland which support MSSQL Server 7, only up to MSSQL Server 6.5 (see the Readme.txt file).

We recommend using the ADO components available with Delphi 5 to connect to MS SQL Server 7.

    ... ;P,
    i also had the same experienced with mysql,
    but dont worry, you already make a progress.

    try to make small database, small table and for first try you can edit database data through mysql admin. for next you can make application interface through delphi.

    for advance, you can downloads some component to connect your delphi application to mysql.

    dont worry, just make a mistake and you get thousand progress ...
