Description

A column marker for use in v:data-set, v:data-grid and v:data-source. This element should exist for each selected column of the SQL expression of the data set. If this is specified under data-set, data-source or data-grid controls, this must be the exact same columns as in SQL statement to be evaluated. If those element is omitted in data-set or data-grid, the columns will be extracted from compilation of the SQL statement. However, this will always be required for calls of stored procedures that return resultsets and for the data-source control.
