Steven Hawkins commented on TEIID-1664:
---------------------------------------

You should inspect the source query / database values directly.  Any non-zero non-null values should be interpreted as true, e.g. "WHERE TRIM(LEADING FROM CASE WHEN SmallA.BooleanValue = 0 THEN 'false' WHEN SmallA.BooleanValue IS NOT NULL THEN 'true' END) = 'true'", which seems fine.

> Teiid - Teradata queries containing LTRIM and RTRIM on the BQT booleanvalue column are returning unexpected results.  The following query should be returning 22 rows but 0 rows are returned. 
> SELECT intkey, booleanvalue FROM BQT1.SmallA WHERE LTRIM(BQT1.SmallA.BooleanValue) = 'true' ORDER BY intkey 
> However, if the LTRIM is removed like (SELECT intkey, booleanvalue FROM BQT1.SmallA WHERE BQT1.SmallA.BooleanValue = 'true' ORDER BY intkey)  22 rows are returned. 
> This should be logged against Teiid 7.4.1
> VDB attached.
