> Key: TEIID-5330

> Project: Teiid
> Issue Type: Bug
> Components: Query Engine
> Affects Versions: 8.12.13.6_4

> The FIRST_VALUE/LAST_VALUE/LEAD/LAG functions always try to return integer, no matter what the type of the column is.
> If integer can be cast to the target type, the query will successfully return, but the return type will be integer instead of the expected one. If integer cannot be cast to the requested type, the query will fail.
> For example, when running this against a CSV source and a string column:
> {noformat}
> SELECT FIRST_VALUE(stringkey) OVER (ORDER BY stringkey) FROM BQT1.smallA
> {noformat}
> This fails with:
> {noformat}
> 14:54:49,328 ERROR [org.teiid.TRANSPORT] (New I/O worker #2) TEIID40113 Unhandled exception, aborting operation: org.teiid.transport.ObjectEncoder$FailedWriteException: org.teiid.core.TeiidRuntimeException: TEIID20001 The modeled datatype integer for column 0 doesn't match the runtime type "java.lang.String". Please ensure that the column's modeled datatype matches the expected data.
