Looking for guidance on using DO BEGIN ... END block with HDBSQL script

Hi folks,

    I have a script file with the following code that runs great in Hana Studio that times the execution of statements that looks like this

DO

BEGIN

  DECLARE starttime timestamp;

  DECLARE endtime timestamp;

  starttime = CURRENT_UTCTIMESTAMP;

select count(*) FROM sflight.sairport;

  endtime =  CURRENT_UTCTIMESTAMP;

  SELECT

  :starttime AS "Start Time"

  , :endtime AS "End Time"

  , NANO100_BETWEEN( :starttime, :endtime)/10000 AS "Elapsed Time (ms)" FROM DUMMY;

END

I end up with my two desired result sets - the first with the results of the main query and the second with the start, end and elapsed time. I then saved the file and called it Airport_Count.sql

When I try to run the file using HDBSQL on my Windows system, I get the following syntax errors related to the DECLARE statements - output using -t debug option

DO

BEGIN

        DECLARE starttime timestamp

* 257: sql syntax error: line 4 col 20 (at pos 30) SQLSTATE: HY000

        DECLARE endtime timestamp

* 257: sql syntax error: incorrect syntax near "DECLARE": line 1 col 1 (at pos 1) SQLSTATE: HY000

        starttime = CURRENT_UTCTIMESTAMP

* 257: sql syntax error: incorrect syntax near "starttime": line 1 col 1 (at pos 1) SQLSTATE: HY000

select count(*) FROM sflight.sairport

| COUNT(*)             |

| -------------------- |

|                   53 |

        endtime =  CURRENT_UTCTIMESTAMP

* 257: sql syntax error: incorrect syntax near "endtime": line 1 col 1 (at pos 1) SQLSTATE: HY000

        SELECT

                :starttime AS "Start Time"

                , :endtime AS "End Time"

                , NANO100_BETWEEN( :starttime, :endtime)/10000 AS "Elapsed Time (ms)" FROM DUMMY

* 467: cannot use parameter variable: STARTTIME: line 2 col 3 (at pos 10) SQLSTATE: HY000

END

Other than encapsulating this code into a stored procedure and running the queries as a call statement to the stored procedure, does anyone have any ideas on how to run scripts with HDBSQL that includes DO BEGIN ... END blocks - see DO BEGIN ... END - SAP HANA SQL and System Views Reference - SAP Library

I see in the debug information that the batch option is "FALSE", but I don't see a command line parameter to set the batch option on. Here is the command line I'm using.

C:\Queries>"C:\Program Files\sap\hdbclient\hdbsql.exe" -i 00 -n awshana:30015 -u SYSTEM -p password -I "Airport_Count.sql" -A -f -t -z  -j -c ";"

Thanks in advance!
