jdbc sql error: statement did not return a result set
Solution 1
Your [p2] stored procedure needs to include SET NOCOUNT ON
right at the beginning to suppress the "n rows affected" counts so JDBC doesn't get confused as to what it should put into the ResultSet:
CREATE PROCEDURE p2
AS
SET NOCOUNT ON;
declare @t1 table(
ref varchar(20)
)
-- ... and so on
For more information on SET NOCOUNT see

Solution 2
use method "execute" instead of "executeQuery".

I have two stored procedures as follows:
create stored procedure p1 as select * from table1 where datediff(day, table1.[date], getdate()) create stored procedure p2 as declare @t1 table( ref varchar(20) ) insert into @t1 select * from table1 where ref = 'some ref' declare @t2 table( fname varchar(20), lname varchar(20), email varchar(1000) ) declare @len int = (select count(ref) from @t1) while @len > 0 begin declare @value varchar(20) = (select top 1 ref from @t1) insert into @t2 select * from table2 where ref = @ref delete from @t1 where ref = @value set @len = (select count(ref) from @t1) end select * from @t2
Java code
.... String query = "Execute [p2]"; try(CallableStatement cstmt = conn.prepareCall(query); ResultSet rs = cstmt.executeQuery()){ ... some code }
The table variable @t1 hold select result from a table 'table1'
The variable @len hold the number of rows in @t1
Using
@len > 0
as condition in while loop, I want to select records from another table 'table2' the table variable @t2 hold the select records from 'table2'The delete statement removes value from @t1 @len set to new number of rows in @t1 the last statement return all the records store in @t2
The first procedure works fine, but the second procedure works only in SQL Server.
I get this an error message in my java application
statement did not return a resultset
I want this to return a result set with the select statement I have at the end of the query.
Please is there a way around this?

Jeff Fol over 7 yearsFor anyone who got the error: "org.pentaho.di.core.exception.KettleDatabaseException: The statement did not return a result set." from PDI this answer also resolves that problem when using JDBC(Native) driver.
