Problem with Cast and table operator

Question

Hi ,
Am using Table and cast opertor to fetch the data from a collection using a ref cursor as follows
OPEN test_cur for
SELECT first_name, Last_name from table(cast( V_Test_collection as Test_Array));
This works but when i tried to fetch the date using following query and ref cursor then i received ORA-00604 and ORA 01003.
I used string containg the query like follows
V_SQL:= ' SELECT first_name, Last_name from table(cast( V_Test_collection as Test_Array))';
OPEN test_cur for V_SQL;
I want to pass this V_SQL variable to another procedure that will use it to apply some business logic.Please help me how to resolve this problem.

Answer 1

Hi, Current procedure is as follows but as per new requirement i have to pass the processed data from this procedure to a common procedure that accepts the string containing the query(Say IN_QUERY) and applies the business logic by fetching the data from this query(IN_QUERY)
CREATE OR REPLACE PROCEDURE GET_USER_INFO_PRC(USER_ID IN NUMBER,
TEST_CUR OUT COMMOM_PKG.OUT_REF_CUR,
O_ERROR_CODE OUT NUMBER,
O_ERROR_LOCATION OUT VARCHAR2,
O_ERROR_MESSAGE OUT VARCHAR2) IS
V_TEST_COLLECTION COMMOM_PKG.WI_INS_SEARCH_ARR_OBJ := WI_INS_SEARCH_ARR_OBJ();
BEGIN
Some buniess logic is applied on V_Test_collection to fetch the date in this block
OPEN TEST_CUR FOR
SELECT FIRST_NAME, LAST_NAME
FROM TABLE(CAST(V_TEST_COLLECTION AS TEST_ARRAY));
Exception handler
END;
