I'm looking for a Hash function in PL/SQL, to get the hash of a varchar.

Here's my code DECLARE l_textToHash VARCHAR2(19) := 'toto123'; l_ccn_raw RAW(128) := utl_raw.cast_to_raw(l_textToHash); l_encrypted_raw RAW(2048); BEGIN dbms_output.put_line('CC: ' || l_ccn_raw); l_encrypted_raw := dbms_crypto.hash(l_ccn_raw, 3); dbms

Using SQL Developer to run queries works good, but I would save a lot of time if I instead of first running the query and then right click the result set and go through the export to csv routine. I was wondering whether it is a way in SQL Developer to: 1) Write the query, and then select that the result of the query should be exported to disk. 2) Write a queue of several queries, each of them writing their results to disk.

It still functions more or less the same. If, at some point, you only need to export a single result set, just right click "on the data" (any column of any row) there you will find an export option. The wizard exports the

I need to be able to run an Oracle query which goes to insert a number of rows, but it also checks to see if a primary key exists and if it does, then it skips that insert. Something like: INSERT ALL IF NOT EXISTS( SELECT 1 WHERE fo.primary_key='bar' ) ( INSERT INTO schema.myFoo fo ( primary_key, value1, value2 ) VALUES ('bar','baz','bat') ), IF NOT EXISTS( SELECT 1 WHERE fo.primary_key='bar1' ) ( INSERT INTO schema.myFoo fo ( primary_key, value1, value2 ) VALUES ('bar1','baz1','bat1') ) SELECT * FROM schema.myFoo; Is this at all possible with Oracle? Bonus points if you can tell me how to do
