Ref kurzor v oracle ako out parameter

First, declare a cursor that accepts two parameters low price and high price. The cursor retrieves products whose prices are between the low and high prices.

Second, open the cursor and pass the low and high prices as 50 and 100 respectively. Then fetch each row in the cursor and show the product’s information, and close the cursor. The SYS_REFCURSOR is a predefined weak ref cursor type supplied by Oracle9i and higher. On the other hand, you can also pass entire collections as parameters, but that’s a different issue, you don’t FETCH from collections, but process their data and/or populate them, as needed. Oracle REF CURSOR With the REF_CURSOR you can return a recordset/cursor from a stored procedure. 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. The example below uses a ref cursor to return a subset of the records in the EMP table.

PROC b (no commits or OUT parameters) PROC c (REF CURSOR OUT parameter and commits) "A" calls "b" using a DBLINK works fine.
