I recently started with MySql, so i might be doing a begginers mistake. Any help is appreciated.

I connect the database in Delphi, define a query with columns of datatypes integer, decimal and varchar.

The problem is when I select a query in Delphi, and debug after opening query, the columns that are varchar does not appear as i if never selected them.

The driver for odbc connector is the latest mysql-connector-odbc-5.1.10

    Speculating: Seems, you are using dbTables -> BDE -> ODBC -> MySQL data access path. BDE skips the fields with unknown data types. Probably Unicode character type is not supported by BDE.

    Possible solutions:

    • try to set ANSI character set for the connection in ODBC connection parameters;
    • use dbGo / ADO data access components;
    • use dbExpress components with MySQL dbExpress driver;
    • use 3d party data access components.
