--------------------------------------------------------------

It is all run as you see it, no alterations was done. The database in use is custom-made one.

And yes, I am not giving same name to all querries columns - see the use case - stored procedure returns something like dozen columns and 50 rows and returnCode is just a single number.

By the way, even if I give in all three SELECTs same alias, the problem persists.

> If in ExecuteSQLRecord processor I use multiple SELECTs as in the following code (note, it all is in single instance of processor), the results are weird. First SELECT (1, 'Yeees') comes through okay as it should, but second and third seems to be processed (additional flowfiles are created), but these are _empty_.
> {code:java}
> SELECT 1 as 'Yeees'
> SELECT 0 as 'Noooooo'
> DECLARE @q int
> SET @q = 0
> SELECT @q AS 'qqq'
> {code}
>  
> The use case is to call stored procedure returning resultset and then select the returnCode:
> {code:java}
> DECLARE @retCode int
> EXEC @retCode = stored_procedure_giving_resultset
>         
> SELECT @retCode AS 'retCode_run'
> {code}
> I am using NiFi 1.12.1, DB is SAP ASE 16.0, db driver is jConnect (TM) for JDBC(TM)/16.0 SP02 PL06 (Build 27337)/P/EBF26829/JDK 1.6.0/jdbcmain/OPT/Wed Mar 15 03:15:38 PDT 2017 and trivially configured JSON recordset writer.
