JAVA调用有返回的存储过程怎么不行啊
存储过程:
drop proc h
create proc h
@a int,@b int,@c int output
as
set @c=@a+@b
go
declare @c int
exec h 1,2,@c output
print @c
在java里面:
CallableStatement cs = null;
try {
cs = DBConn.getConnection().prepareCall( "{call h(?,?,?)} ");
cs.setInt(1,1);
cs.setInt(2,2);
cs.registerOutParameter(3, java.sql.Types.INTEGER);
cs.execute();
int temp=cs.getInt(3);
cs.close();
System.out.println(temp);
} catch (
ClassNotFoundException ex) {
ex.printStackTrace();
} catch (
SQLException ex) {
ex.printStackTrace();
}
出错内容:
java.sql.SQLException: Output parameter not allowed as argument list prevents use of RPC.
