-------------------------------------
When you remove the BigDecimal column does the cast pushed down?

> URL: https://issues.jboss.org/browse/TEIID-5117
> Project: Teiid
> Issue Type: Bug
> Components: JDBC Connector
> Affects Versions: 8.12.x-6.4
> Reporter: Andrej Šmigala
> Assignee: Steven Hawkins
>
> 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).
