Unable to fetch Resultset from StoredProc in Java

Question

We are trying to execute stored proc in Java which looks like as below,

CREATE PROCEDURE [dbo].[MyProc] 
(
    @input1 varchar(20),
    @input2 varchar(20),
    @responsecode       varchar(10) output
)
AS

//Implementation

SELECT @a,@b,@c,@d;

SELECT @responsecode;

Java Code looks like as below,

callableStatement = conn.prepareCall("{call MyProc("2","2"))}");
callableStatement.registerOutParameter(3, Types.VARCHAR);           
callableStatement.registerOutParameter(4,Types.JAVA_OBJECT);

As you can see , we are trying to get two output parameters from stored proc,

We are able to get response code at index 3 , however @a,@b,@c,@d should come as resulset at index 4 ( may be I am wrong)

Can you please give me some poninters on getting resultset for such kind of stored proc.

when I execute this stored proc in Microsoft SQL Server Managment Studio, I can see two types of responses, first is resultset and other one is ResponseCode as below,

Answer 1

You're mixing up resultsets with output parameters. The stored procedure in your post only has one output parameter, @responsecode .

Output parameters do not need to be selected out after you set them in a proc:

create procedure testsp (@param int output)
as
    set @param = 1

GO

declare @param int

exec testsp @param output


select @param

So remove the SELECT @responsecode; , and also the 4th registered parameter in your callable statement.

To get to your data, iterate over the resultset returned by executeQuery() .
