Question

I have the following sql query:

UPDATE 
(SELECT * FROM table_A INNER JOIN table_B 
ON table_A.id=table_B.a_fk 
WHERE table_A.batch=10) AS TBL_1 
SET TBL_1.b_name = "test" WHERE TBL_1.a_fk = 67532;

When i run it, i get the following error message:

The target table TBL_1 of the UPDATE is not updatable.

I need to update the column ‘b_name’ in table_B where the batch value is 10 in table_A.

Any help is most appreciated.

Answer 1

update table_B b 
set b.b_name = 'test'
where b.a_fk in 
(
select id from table_A where batch=10
)
