I'm led to believe that since Oracle stored procedures return result sets using refcursors, that a different approach is necessary for calling them. There are 2 basic types: Strong ref cursor and weak ref cursor For the strong ref cursor the returning columns with datatype and length need to be known at compile time. HI, I currently have a stored procedure (SP) within Oracle that has an OUT parameter of type SYS_REFCURSOR, this SP executes as expected within Oracle. Oracle 9i introduced the predefined SYS_REFCURSOR type, meaning we no longer have to define our own REF CURSOR types. It represents a cursor or a result set in Oracle Database. Cursor expressions as arguments to functions called from SQL: 25. I have procedure with an out parameter returning a ref cursor and fuction result set returning ref cursor in Oracle. The following is a list of topics that explain how to use Cursors in Oracle / PLSQL:. We can only pass values to the cursor; and cannot pass values out of the cursor through parameters. Because OCI8 uses "prefetching" to greatly improve returning query results, but Oracle doesn't support prefetching for REF CURSORs, application performance using REF CURSORs can be greatly improved by writing a PL/SQL function that pulls data from the REF CURSOR and PIPEs the output.
