Description
Executes the SQL command associated with the dataset.
Data.SqlExpr.TCustomSQLDataSet.PSExecute inherits from Data.DB.TDataSet.PSExecute. All content below this line refers to Data.DB.TDataSet.PSExecute.
Executes the SQL command associated with the dataset.
The provider component calls PSExecute to implement its Execute method. If the dataset represents a query or stored procedure that does not return a cursor, this method executes the query or stored procedure. If the provider Options include poAllowCommandText and the dataset supports the PSSetCommandText method, the statement specified by PSSetCommandText may be executed instead.
If there is no statement to execute, PSExecute raises an EDatabaseError exception.
This method is an implementation of the IProviderSupport.PSExecute method and, by default, it raises an exception, because the dataset does not implement a provider by default. To use it, every TDataSet descendant must override it in its specific way.
