----------------------------------
Summary: ctxExpression logic doesn't reset the context (was: ctxQuery logic doesn't reset the context)
> ctxExpression logic doesn't reset the context
> ---------------------------------------------

> Key: TEIID-4417
> URL: https://issues.jboss.org/browse/TEIID-4417
> Project: Teiid
> Issue Type: Bug
> Components: OData
> Affects Versions: 8.12
> Reporter: Steven Hawkins
> Assignee: Steven Hawkins
> Priority: Critical
> Fix For: 9.1

> When the ODataExpressionToSQLBuilder changes the ctxExpression in most instances it needs to revert back to the ctxQuery, but currently does not.
> For example reordering the predicate:
> /odata4/vdb/PM1/G1?$filter=e1 eq $root/G1(1)/e1
> to
> /odata4/vdb/PM1/G1?$filter=$root/G1(1)/e1 eq e1
> results in a source query:
> SELECT g0.e1, g0.e2, g0.e3 FROM PM1.G1 AS g0 WHERE (SELECT g1.e1 FROM PM1.G1 AS g1 WHERE g1.e2 = 1) = (SELECT g1.e1 FROM PM1.G1 AS g1 WHERE g1.e2 = 1) ORDER BY g0.e2
> That has both sides of the predicate as subqueries.
