TdxServerModeQueryDataSource Class

The base class for query-based server mode data sources.

Declaration

TdxServerModeQueryDataSource = class(
    TdxServerModeCustomDataSource
)

Remarks

This class extends the ancestor class with the SQL property, which allows you to specify the SQL statement to be executed when querying the target database for data.

TdxServerModeQueryDataSource descendants – TdxServerModeFireDACQueryDataSource, TdxServerModeDBXQueryDataSource and TdxServerModeADOQueryDataSource – extend the base class with the capability to access data via a FireDAC, dbExpress, or ADO connection object, respectively.

Important

Query-based server mode data sources do not support InterBase databases.
