ExecuteResultSet() method

UL Ext.: Executes a SQL SELECT statement and returns the result set as a ULResultSet.

Syntax
Visual Basic
Public Function ExecuteResultSet() As ULResultSet
C#
public ULResultSet ExecuteResultSet();
Return value

The result set as a ULResultSet object.

Remarks

The statement is the current ULCommand object, with the ULCommand.CommandText and any ULCommand.Parameters as required. The ULResultSet object is an editable result set on which you can perform positioned updates and deletes. For fully editable result sets, use ULCommand.ExecuteTable() or a ULDataAdapter.

If the ULCommand.CommandType is System.Data.CommandType.TableDirect, ExecuteReader performs an ULCommand.ExecuteTable() and returns a ULTable downcast as a ULResultSet.

ULCommand.ExecuteResultSet supports positioned updates and deletes with Dynamic SQL.

Example
cmd.CommandText = "SELECT id, season, price FROM OurProducts";
ULResultSet rs = cmd.ExecuteResultSet();
while( rs.Read() ) {
    string season = rs.GetString( 1 );
    double price = rs.GetDouble( 2 );
    if( season.Equals( "summer" ) && price < 100.0 ) {
        rs.SetDouble( 2, price * .5 );
        rs.Update();
    }
    if( season.Equals( "discontinued" ) ) {
        rs.Delete();
    }
}
rs.Close();
