RE: Joining two same tables in different libraries using SQL


-----Message d'origine-----
[mailto:midrange-l-bounces@xxxxxxxxxxxx] De la part de dina ramzy
SELECT A.FLD12, B.FLD12
FROM LIB1.TABLE1 A, LIB2.TABLE1 B
WHERE
A.KEYFLD1 = B.KEYFLD1 AND
A.KEYFLD2 = B.KEYFLD2



Now I want to update table A and set FLD12 to be the same as
the corresponding one in table B (A.FLD12 = B.FLD12)

Could you please help me in writing this SQL statement.


UPDATE update_table U
SET myfield = (SELECT M.MyField FROM MasterTable M WHERE U.MyKey=
M.MyKey) WHERE U.MyKey IN (SELECT U.MyKey FROM MasterTable M)

And read the valuable lesson from Charles Wilt to myself here :
