The columns are casted to varchar2 with specific widths (9,4,10,10,10). The casting allows me to ensure column widths are constant. In SQL Developer 1.5, printing script output (using F5 from SQL worksheet) displays the contents of the cursor nicely as: MY_FUNCTION(input1,input2,input3) --------------------------------- COLUMN1 COLU COLUMN3

问题 I'm trying to call a stored procedure in Oracle and show the results of the call, the problem is that it crashes on the line FETCH v_cur into v_a; with error: ORA-06504: PL/SQL: Return types of Result Set variables or query do not match.
