Oracle到DB2 - 迁移

Question

我必须将所有过程从Oracle迁移到DB2数据库。我想知道，我如何在程序内部调用函数，如下一个

功能脚本

create or replace 
PACKAGE GPRSG001

AS
    -->> Variáveis <<--
    TYPE v_trLinha  IS RECORD (v_sColuna VARCHAR2(32767));
    TYPE v_ttTabela IS TABLE OF v_trLinha;   

FUNCTION GPRS7004(
            -->> Parâmetros de Entrada <<--
            pe_sTexto VARCHAR2)
        RETURN VARCHAR2;
    END GPRSG001;

Oracle脚本

BEGIN
        SELECT CCOOP
          INTO ps_iPkCooperativa
          FROM COOP
         WHERE GPRSG001.GPRS7004(NDOCTO || ICOOP) = v_sParametrosFormatados;
        EXCEPTION
            WHEN NO_DATA_FOUND
            THEN ps_iPkCooperativa := 0;
    END;
