  • Hello Malar, First of all Vertica External procedures are not like other database procedures. The procedures in vertica don't give output. They can give output in 0 or 1 0 stands for procedure executed successfully 1 stands for procedure not executed successfully Secondly, Every shell script which is used for External procedure should end with exit 0 as per Vertica Documents The file should end with exit 0, and exit 0 must reside on its own line. This naming convention instructs Vertica to return 0 when the script succeeds.
  • Hi Navin , Thanks for the reply . Yes as u said Exit 0 is must. When I run a procedure with out any argument I get the output with exit 0 status. FYI: create procedure a14() as 'p1.sh' language 'external' user 'dbadmin'; CREATE PROCEDURE dbadmin=> select a14(); INFO 4427: Procedure reported: id | name | salary ----+------+-------- 1 | a | 12 2 | b | 12 3 | c | 12 (3 rows) a14 ----- 0 (1 row) But I gte an error when I run a procedure with argument . Can U pls tell me where I went wrong (in the previous post). Or How to achieve this goal . Thanks, Malar
