PLS-00400
Error: PLS-00400: different number of columns between cursor SELECT statement and return value
Causa: In a cursor declaration, a return type (such as RETURN emp\%ROWTYPE) was specified, but the number of returned column values does not match the number of select-list items.
Acción: Change the cursor return type or the select list so that the number of returned column values matches the number of select-list items.
