I'm writing some SQL for a report (this is my first time actually writing SQL so don't slam my syntax too much, lol) and the subquery seems to be failing. I'm not sure why because the report compiles just fine and I can get it into Jaspersoft Studio before it errors out when trying to preview it. Am I even doing the subquery correctly?
Thanks in advance.

SHARE_ESCROW.CLOSE_DATE,

WHERE

SHARE_ESCROW.CLOSE_DATE IS NULL AND

Edit: Here's the error:

The message you see in the log:
DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=CMURPHY.LOAN
means that the object (in your case a table) LOAN in the schema CMURPHY cannot be found (SQLCODE -204). As others have mentioned in comments, the only table reference in your query that is missing the explicit schema is this:
FROM
CORE.COLLATERAL AS COLLATERAL INNER JOIN LOAN ON LOAN.SERIAL ...
---------------------------------------------^^^^
so the database server by default looks for that table in the default schema, the one matching your user ID (CMURPHY). Apparently it's not there.
Add the explicit schema name to the table reference:
FROM
CORE.COLLATERAL AS COLLATERAL INNER JOIN CORE.LOAN AS LOAN ON LOAN.SERIAL ...
