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

What schema do you use? It sounds like you're not giving the same column name across your queries.

> 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.
