Steven Hawkins resolved TEIID-5326.
-----------------------------------
Fix Version/s: 10.3
10.1.4
10.2.1
Resolution: Done
Correct the sybase iq (using the explicit convert format shown) and the sybase translator (using a space) timestamp to string conversion logic. Also added a simpler timestamp conversion for newer versions of sybase.

> 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
> Fix For: 10.3, 10.1.4, 10.2.1
>
>
> 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}
> For more formatting options see [SyBooks Online|http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc38151.1510/html/iqrefbb/Convert.htm]
