Hi,
It is just a string literal I used as an example. Replacing it with "1"
does not affect the issue in any way

Why not just try the standard way
SELECT * FROM P WHERE EXISTS(SELECT 1 FROM B WHERE P.ID <http://P.ID>
= B.ID <http://B.ID>)
You don't need '*' that is not standard SQL as far as I know

Hi,
I am having an issue with correlated sub-queries such as the following
SELECT * FROM P WHERE EXISTS (SELECT '*' FROM B WHERE P.ID
<http://P.ID> = B.ID <http://B.ID>)
Both Beeline and Java JDBC client falied with the following message
Error: Error while compiling statement: FAILED: SemanticException
[Error 10250]: Line 1:51 Invalid SubQuery expression 'ID': For
Exists/Not Exists operator SubQuery must be Correlated.
(state=42000,code=10250)
However the query succeeds if the cross-referenced column is
referred to using lowercase. Note that all other references are
case-insensitive and I can mix the case in whichever way I want.
SELECT * FROM P WHERE EXISTS (SELECT '*' FROM B WHERE P.id = B.ID
<http://B.ID>)
The expected behavior for me will be that all identifiers are
case-insensitive.
Is it a bug or am I missing something here?
