Question

I am getting problem for UPDATE query in sqlite .

 UPDATE Table1 T1, Table2 T2 SET T1.USE_MHE = T2.USE_MHE WHERE T1.EQ_NAME= T2.EQ_NAME 

Above query works fine for MS access ADO connection.
But for SQLite it’s looks like using table shortcut is not possible (Table1 T1) I have 100’s of such query to update. Please let me know how table shortcut can be used in SQLite update query.,

Your problem is not aliases that you’re using. Your UPDATE clause is wrong. Try:

UPDATE 
   Table1 AS T1 
SET 
   T1.USE_MHE = (SELECT T2.USE_MHE FROM Table2 AS T2 WHERE T1.EQ_NAME = T2.EQ_NAME)
WHERE
   EXISTS(SELECT * FROM Table2 AS T2 WHERE T1.EQ_NAME = T2.EQ_NAME);
