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

             Summary: Several SELECTs does not return correct values
                 Key: NIFI-7983
                 URL: https://issues.apache.org/jira/browse/NIFI-7983
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.12.1
            Reporter: Michal Šunka
         Attachments: NiFi_SELECTs.jpg

If in ExecuteSQLRecord processor I use multiple SELECTs as in following (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 selecr the returncode:
{code:java}
DECLARE @retCode int

EXEC @retCode = stored_procedure_giving_resultset
        
SELECT @retCode AS 'retCode_run'
{code}
I am using NiFi 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.
