    [ https://issues.jboss.org/browse/TEIID-5117?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13481269#comment-13481269 ] 

Andrej Šmigala commented on TEIID-5117:
---------------------------------------

[~rareddy] I don't understand the question. If you're asking whether a different cast gets pushed down then yes, running e.g.

{code:sql}
select cast(stringnum as integer), cast(intnum as integer), cast(shortvalue as integer) from Source.smalla
{code}

is pushed down as 

{code:sql}
SELECT cast(g_0.StringNum AS Int32), g_0.IntNum, cast(g_0.ShortValue AS Int32) FROM dvqe..SmallA AS g_0
{code}

and returns the correct results

> Casting any value obtained from an Osisoft PI datasource results in NULL, regardless of the original value.
> E.g. a query such as 
> {code:sql}
> select cast(stringnum as bigdecimal), cast(intnum as bigdecimal), cast(shortvalue as bigdecimal) from Source.smalla
> {code}
> returns result set full of NULLs.
> The SOURCE SRC COMMAND in teiid-command.log for this query is however
> {code:sql}
> SELECT g_0.StringNum, g_0.IntNum, g_0.ShortValue FROM dvqe..SmallA AS g_0
> {code}
> i.e. the cast is not pushed down (as Osisoft doesn't support bigdecimal datatype).
