Netezza UPDATE from one table to another
提问by Ram
This is my query that does not work in Netezza:
这是我在 Netezza 中不起作用的查询：
UPDATE TABLE1 A
SET A.COL1= (SELECT DISTINCT B.COL1 FROM TABLE2 B WHERE B.ID= A.ID AND B.DeptID=104)
WHERE A.DeptID=3
How do I re-write this query? Please help.
如何重新编写此查询？请帮忙。

UPDATE TABLE1 A
SET A.COL1 = B.COL1
FROM TABLE2 B
WHERE
A.ID = B.ID AND
A.DeptID = 3 AND
B.DeptID = 104;
