Question

I am inserting a record within a transaction and then later I am retrieving the same record via an Oracle function. The oracle function is returning no records. My DBA told me that Oracle functions do not operate inside a transaction. How do I get around this?

Example:
Begin transaction using the oracle provider

Execute some SQL:

INSERT OWNER
(FIRST_NAME, LAST_NAME)
VALUES
(‘JOHN’, ‘SMITH’)

Get the record back within the transaction from a function (71 is an example ID):
select * from table (GET_OWNER_DETAILS_FNC (71) )

Here is the Oracle Function:

CREATE OR REPLACE FUNCTION "AROH"."GET_OWNER_DETAILS_FNC" (p_owner_information_oid  in aroh_owner_information.owner_information_oid%type ) 
return OWNER_DETAILS_TABLE_TYPE_FNC

IS 
PRAGMA AUTONOMOUS_TRANSACTION; 

v_owner_details_set   OWNER_DETAILS_TABLE_TYPE_FNC := OWNER_DETAILS_TABLE_TYPE_FNC();

Answer 1

The AUTONOMOUS_TRANSACTION pragma means that the function operates in the context of a separate transaction. By default (see http://docs.oracle.com/cd/B19306_01/server.102/b14220/consist.htm#sthref1972) this uses the “read committed” isolation level, meaning that, when the transaction queries data, it sees only data that was committed before the query began. Since the data you inserted has not been committed, this means that the function can’t see it.
