Parameters:

`dataset_name`	The DataSet reference to be used. If you do not specify `dataset_name`, the current DataSet is used.
`datarows_name`	The name of a DataRows cursor.
`column_name`	The names of the columns in the DataTable to specify in the DataRows cursor.
FOR `row_state` DATAROWS	Identifies the DataRows to use in a DataTable based on the `row_state` value.
`datatable_name`	The name of the DataTable on which the DataRows cursor is defined.
`search_conditions`	Any valid expression that can follow the standard SQL WHERE clause.
`sort_clause`	Any valid expression that can follow the standard SQL ORDER BY clause.
`cursor_name`	The name of a DataRows cursor to be associated with this DataRows cursor (as either a parent or a child.)
`relation_name`	The name of the constraint which specifies the parent-child relationship between this DataRows cursor and the `cursor_name` cursor referenced above. `relation_name` is defined in the DECLARE DATASET statement.

Comments:

The standard cursor manipulation statements (OPEN, FETCH, DELETE (POSITIONED), UPDATE (POSITIONED) and CLOSE) are also applicable to an ADO.NET DataRows cursor.

In addition to the standard WHERE clause, the DECLARE DATAROWS statement allows you to navigate parent-child relationships of related DataRows cursors with the WHERE CHILDREN and WHERE PARENTS clauses.

Example:

     EXEC ADO
        DECLARE drOrder DATAROWS  
        FOR SELECT OrderID, OrderDate FROM Orders
        WHERE CHILDREN OF drCust(custord)
     END-EXEC
