    Ref_cursor issue

    First off, bear with me since I'm a newbie..

    I have a function that returns a ref_cursor... I need (within the function) to check if the ref_cirsor is empty, and if it is, call another function to populate the ref_cursor. basically if ithe data isn't in the database, it's gonna be in the archieve database, which has the same table/layouts.

    Here's a snipet of code... Any help would be appreciated.

    FUNCTION Get_summary_by_policy_number(N_POLICY_IN IN policy.N_POLICY%TYPE)
    RETURN REF_CURSOR
    AS
    claim_summary_cursor ref_cursor;
    BEGIN

    open claim_summary_cursor for
    SELECT CLAIM.N_CLAIM_NUMBER, CLAIM.C_CLAIM_STATUS,
    POLICY.N_POLICY,
    LOSS.D_DATE,LOSS.T_FNOL_LOSS_DESC, LOSS.C_LOSS_TYPE,
    CN.M_FIRST_NAME, CN.M_MIDDLE_NAME, CN.M_LAST_NAME
    FROM
    claim CLAIM,
    policy POLICY,
    loss LOSS,
    client_name CN,
    ins_involvement II,
    involvement_role IR
    WHERE
    CLAIM.N_POLICY_ID = POLICY.N_POLICY_ID AND
    CLAIM.N_LOSS_ID = LOSS.N_LOSS_ID AND
    CLAIM.N_CLAIM_ID = II.N_ENTITY_ID AND
    II.N_INS_INVL_ID = IR.N_INS_INVL_ID AND
    II.N_PREF_NAME_ID = CN.N_NAME_ID (+) AND
    CLAIM.C_CLAIM_STATUS <> 'ER' AND
    CLAIM.C_RCD_DEL <> 'Y' AND
    CLAIM.C_CLAIM_FILE_TYPE NOT IN ('E','CN') AND
    LOSS.C_RCD_DEL <> 'Y' AND
    POLICY.C_RCD_DEL <> 'Y' AND
    II.C_RCD_DEL <> 'Y' AND
    IR.C_RCD_DEL <> 'Y' AND
    IR.C_STATUS <> 'ER' AND
    IR.C_INVL_ROLE = 'NIS' AND
    POLICY.N_POLICY = RPAD(N_POLICY_IN,12)
    ORDER BY D_DATE DESC;

    IF*claim_summary_cursor%FOUND THEN
    claim_summary_cursor := claiminq_proc.arch_claim_inquiry.Get_summary_by_policy_number(N_POLICY_IN) ;
    End If;



    return claim_summary_cursor;


    END;

    Cool %isopen

    The open cursor statement will only return "%ISOPEN"{=TRUE} variable after executing. It will NOT return any other of the cursor variables (like %ROWCOUNT).

    okay..

    If I use "%ISOPEN"{=TRUE} after I open the cursor, and it's empty ( no rows selected) would %ISOPEN still return tru regardless if rows were selected?


    And thanks for your reply

    YES, it will return TRUE regardless if rows selected or not.
