通过JMeter调用DB2存储过程时的语法错误

Question

I am trying to call a DB2 Stored Procedure which has two Input parameters (Timestamp, both) and one Output parameter (Integer). I am trying to do so from JMeter JDBC Sampler and getting sql syntax exception.

Response code: 42884 -440
Response message: com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-440, SQLSTATE=42884, SQLERRMC=PROCEDURE;DEVSCHEMA.GET_ROW_COUNT, DRIVER=4.19.26

Response headers:
1272084586, URL=jdbc:db2://<db2IP>:<port>/DB2T, UserName=<someUserName>, IBM Data Server Driver for JDBC and SQLJ 

From IBM Documentation I got to know that this error happens when either Stored procedure is not present - which is not the case, Schema name incorrect - which is also not the case, mismatching number of parameters - I verified this but I am doubtful at this point because JMeter provides separate fields to be filled up and in one of the fields I might be passing incorrect value.

I have not much knowledge of JMeter but with the help from apache JMeter documentation I have set below values to the Sample Fields.

Query Type: Callable Statement 
Query: CALL DEVSCHEMA.GET_ROW_COUNT(?,?,?)
Parameter Values: ${__time(yyyy-MM-dd HH:mm:ss,)},${__time(yyyy-MM-dd HH:mm:ss,)},0 
Parameter Types: IN TIMESTAMP,IN TIMESTAMP,OUT INTEGER 
Variable Names:VARCOUNT 
Handle ResultSet: Store as a String

Can anyone please figure out where am I making a mistake? Many thanks.

The issue has been resolved. It was literally something else about which I never gave a thought. When I got the same error when I tried to access the same SP using Java code, I contacted DB2 team who wrote the Stored procedure. And issue was with the SP. According to them execute access was given so after drilling here and there they preferred to create a new SP which worked without any issues. Else everything was perfect from JMeter side.
