Create procedure data_wtptest (IN in_taskid_timestamp varchar (30 ),
OUT o_err_no int, OUT o_err_msg varchar (1024 ))
Language SQL P1: BEGIN ATOMIC
Declaration start
Temporary Variable Error variable
Declare sqlcode integer default 0;
DECLARE SQLStmt varchar (1024) default '';
DECLARE r_code integer default 0;
DECLARE state varchar (1024) default 'aaa ';
 
Record the current work of the program
DECLARE at_end int DEFAULT 0;
DECLARE t_destnetid int default 0;
DECLARE t_recvid varchar (30) default '';
DECLARE SP_Name varchar (50) default 'data _ integrate ';
Declare the cursor value in the DB2 Stored Procedure

Declare Dynamic Cursor storage variables
DECLARE stmt1 STATEMENT;
DECLARE c1 cursor for stmt1;
Declarative error handling

Declare exit handler for sqlexception begin set r_code = SQLCODE;
Set o_err_no = 1;
Set o_err_msg = 'process [' | state | '] error,' | 'error code SQLCODE: [' | CHAR (r_code) | '].';
Insert into fcc_sp_log (object, name, value) values (SP_Name, in_taskid_timestamp, o_err_msg );
End;
DECLARE continue HANDLER for not found begin set at_end = 1;
Set state = 'found 0 rows of records or has reached the end of the record .';
