                 URL: https://jira.jboss.org/browse/TEIID-1224

          Issue Type: Bug
          Components: Query Engine

Several BQT Stored Procedures are returning "java.lang.ClassCastException: org.teiid.query.processor.relational.ProjectNode cannot be cast to org.teiid.query.processor.relational.AccessNode"

An example of a failing query is:  SELECT IntKey, IntNum FROM BQT2.MediumB WHERE IntNum = (EXEC SP.sp_count_rows_between(10, 20)) ORDER BY IntKey

Log file for this query is attached.

Engineering analysis indicates the issue is related pre-evaluation of uncorrelated subqueries.
