TdxServerModeDBXQueryDataSource Class

The dbExpress query-based server mode data source.

Declaration

TdxServerModeDBXQueryDataSource = class(
    TdxServerModeQueryDataSource
)

Remarks

This server mode data source uses a dbExpress connection object (TSQLConnection) to access data. TdxServerModeDBXQueryDataSource extends its ancestor class with members that allow you to do the following:

Specify a dbExpress connection object and connection-specific settings (Connection and Options);
Retrieve the names of schemas defined in a target database (PopulateSchemaNames).

You can use the TdxServerModeDBXQueryDataSource component as a data source for the ExpressQuantumGrid control in server mode.

Important

As with other query-based server mode data sources, TdxServerModeDBXQueryDataSource does not support InterBase databases.
