Prepared Statements
Executing Prepared Statements with FireDAC Classes
By default, TFDQuery prepares the query to avoid recompiling the same query over and over.
FDQuery1.SQL.Text := 'SELECT * FROM Banks WHERE Description=:Description' FDQuery1.ParamByName('Description').AsString := 'Bob'; FDQuery1.Open;
Notes
- If you need to execute a command only once, set ResourceOptions.DirectExecute to true.
- The connection must be active and open while a statement is prepared.
