-208 THE ORDER BY CLAUSE IS INVALID BECAUSE COLUMN column-name IS NOT PART OF THE RESULT TABLE
Explanation
The statement is invalid because a column (column-name) specified in the ORDER BY list does not appear in the result table (that is, it is not specified in the SELECT-list). Only columns in the result table can be used to order that result when the fullselect of the SELECT statement is not a subselect.
System action
The statement cannot be processed.
Programmer response
Correct the syntax of the statement, either by adding the specified column to the result table, or deleting it from the ORDER BY clause.
