DB2：无法插入或从临时表中选择

Question

I have tried lots of permutations of DECLARE and CREATE but I can't display any data from my temporary table. Here's the latest iteration:

DECLARE GLOBAL TEMPORARY TABLE session.temporary_table (ACTNO CHAR); 
INSERT INTO session.temporary_table VALUES ('1'), ('2'); 
SELECT * FROM session.temporary_table; 
SELECT DISTINCT ACTKWD FROM JMILLER.ACT INNER JOIN session.temporary_table ON ACT.ACTNO = session.temporary_table.ACTNO; 
DROP TABLE session.temporary_table;

The first SELECT is to see if there's anything in the temporary_table . Which there doesn't seem to be.

Even though when I test the query in this tool it says every line of it completed correctly.

What am I doing wrong in my sql statements? I was having trouble with permissions earlier but that seems to be fine now and I'm not getting any errors, so it must be in my code.

Answer 1

You did not add the clause ON COMMIT PRESERVE ROWS .

Also see if you could make things simpler by using CTE (the WITH statement)

Answer 2

修改为

 SELECT DISTINCT ACTKWD FROM JMILLER.ACT t0 INNER JOIN session.temporary_table t1 ON t0.ACTNO = t1.ACTNO;
