property OnExecuteSelectColumn: TEWBExecuteDataSetColumnCommandEvent

Usage

This event is triggered when a Select<Column> dataset command is being executed while retrieving a BLOB column for a dataset. The Params property indicates the incoming parameters for the command execution. The RowsAffected variable parameter should be populated with the number of rows that were selected during the command execution, and the DataSet variable parameter should be populated with the TDataSet descendant class instance that will be used for returning the BLOB column and, optionally, its MIME type.
