Declaring a cursor in DB2 with other activity results in failed deployment

Question

After looking around all over the Internet, I have to come back to SO :).

Summary:

DB2 stored procedure doesn't deploy when 3 lines are uncommented, otherwise it works perfectly fine. Any guesses why? FYI, I am rather new to DB2.

Procedure code:

CREATE PROCEDURE TESTDB2.PROC_NAME_GOES_HERE(
    IN  P_ID INT ,
    IN  P_SEQ_NO_2 SMALLINT,
    IN  P_SEQ_NO DECIMAL(3,0))

    RESULT SETS 1
    LANGUAGE SQL
    NOT DETERMINISTIC
    CALLED ON NULL INPUT
    FENCED
    MODIFIES SQL DATA
    COLLID TESTDB2
    WLM ENVIRONMENT TDB2ENV
    ASUTIME LIMIT 5000000
    RUN OPTIONS 'NOTEST(NONE,*,*,*)' 
P1: BEGIN

    DECLARE V_SEQ_NO DECIMAL(3,0);
    DECLARE V_LVL INT;

    DECLARE GLOBAL TEMPORARY TABLE SESSION.SEQ_NO_TABLE
    (LVL INT NOT NULL, SEQ_NO DECIMAL(3,0) NOT NULL);

    SET V_LVL = 0;

    INSERT INTO SESSION.SEQ_NO_TABLE(LVL, SEQ_NO)
    VALUES(V_LVL, P_SEQ_NO);

    --**************************************************--
    --  If I uncomment following 3 lines, deployment fails --

    --DECLARE CUR_FFB CURSOR WITH RETURN FOR
    --SELECT * FROM SESSION.SEQ_NO_TABLE;
    --OPEN CUR_FFB;

END P1

Error:

Deploy TESTDB2.PROC_NAME_GOES_HERE(INTEGER, SMALLINT, DECIMAL(3, 0))

Answer 1

So finally it worked for me with slight modification, adding a solution for anyone who might come across this confusion later.

Solution - Declare the cursor before you declare the table.

Only thing that still confuses me is how can I create a cursor on an object that doesn't even exist yet.

CREATE PROCEDURE TESTDB2.PROC_NAME_GOES_HERE(
IN  P_ID INT ,
IN  P_SEQ_NO_2 SMALLINT,
IN  P_SEQ_NO DECIMAL(3,0))

    DECLARE CUR_FFB CURSOR WITH RETURN FOR
    SELECT * FROM SESSION.SEQ_NO_TABLE;

    DECLARE GLOBAL TEMPORARY TABLE SESSION.SEQ_NO_TABLE
    (LVL INT NOT NULL, SEQ_NO DECIMAL(3,0) NOT NULL);

    SET V_LVL = 0;

    INSERT INTO SESSION.SEQ_NO_TABLE(LVL, SEQ_NO)
    VALUES(V_LVL, P_SEQ_NO);

    OPEN CUR_FFB;

END P1
