Can you provide the output from explain analyze verbose SELECT count(*) FROM table1 a WHERE EXISTS (SELECT 1 FROM table2 WHERE id::VARCHAR = (SELECT id FROM table3 b WHERE b.column = a.column))
if that fails
explain verbose SELECT count(*) FROM table1 a WHERE EXISTS (SELECT 1 FROM table2 WHERE id::VARCHAR = (SELECT id FROM table3 b WHERE b.column = a.column))
That will indicate what SQL it's trying to run on the remote server and will provide a clearer indication of the issue.
Hi, I'm trying to execute the following query:
SELECT count(*) FROM table1 a WHERE EXISTS (SELECT 1 FROM table2 WHERE id::VARCHAR = (SELECT id FROM table3 b WHERE b.column = a.column))
table1 and table3 are both remote mysql tables. But I get the following error:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?))' at line 1
If I execute the query directly with a value, it succeeds.
SELECT EXISTS (SELECT 1 FROM table2 WHERE id::VARCHAR = (SELECT id FROM table3 b WHERE b.column = 1234));
