Description
Resets the dataset so that it is positioned on the first record.
Data.SqlExpr.TCustomSQLDataSet.PSReset inherits from Data.DB.TDataSet.PSReset. All content below this line refers to Data.DB.TDataSet.PSReset.
Resets the dataset so that it is positioned on the first record.
The provider calls PSReset to reposition the dataset on the first record before fetching records.
This method is an implementation of the IProviderSupport.PSReset method and, by default, is blank. To use it, every TDataSet descendant must override it in its specific way.
