             Summary: SAP IQ timestamp conversion to varchar wrong resulting format
                 Key: TEIID-5326
                 URL: https://issues.jboss.org/browse/TEIID-5326
             Project: Teiid
          Issue Type: Bug
    Affects Versions: 8.12.13.6_4
            Reporter: Jan Stastny
            Assignee: Steven Hawkins


Following Teiid query:
{code:sql}
SELECT TimeStampValue, LOWER(TimeStampValue) FROM BQT1.SmallA
{code}
is pushed as:
{code:sql}
SELECT g_0."timestampvalue" AS c_0, lcase(stuff(stuff(convert(varchar, g_0."timestampvalue", 102), 5, 1, '-'), 8, 1, '-')+convert(varchar, g_0."timestampvalue", 8)) AS c_1 FROM "bqt-server"."dvqe"."SmallA" AS g_0
{code}
and returns the string representation of timestamp as:
2000-01-0100:00:00
2000-01-0100:00:01
...
Notice the missing space between date and time part.

SAP IQ is capable of converting the value implicitly, e.g. when I issue query
{code:sql}
SELECT TimeStampValue, LOWER(TimeStampValue) FROM SmallA
{code}
directly against SAP IQ instance, I get following string format:
2000-01-01 00:00:00.000
2000-01-01 00:00:01.000
....

The same results are returned if I use an explicit convert like:
{code:sql}
SELECT TimeStampValue, LOWER(CONVERT(varchar,TimeStampValue,121)) FROM SmallA
{code}
