# 4832 Queries that Reference Views Can Experience AVs During Unprepare

We have a constellation of multiple databases per session.
A master-DB and one DB for each project.

A query with a join of a view in the master results in an AV while repeating the execution.

I was able to reproduce it on EDB-Manager with a sample.
Please look at the DBs in the attachment.

1. prepare both queries

2. unprepare one of them

3. repeat the prepare/execution and you will see an AV.
Access violation at address 007127C5 in module 'edbmgr.exe'. Read of address 000000B0

Query 1:

SELECT member.*, A.name
FROM c1.member M
LEFT OUTER JOIN md.vw_adr A ON A.id = M.fid

Query 2:

SELECT member.*, A.name
FROM c2.member M
LEFT OUTER JOIN md.vw_adr A ON A.id = M.fid
