Question

我正在使用一个我需要动态SQL查询的顶级环境。 Apex在＆＃34;经典报告（基于功能）＆＃34;的帮助下提供此api。我希望你把注意力吸引到第8行。当我将它粘贴到stackoverflow中时，我的appoligies间距变得混乱。现在问题是我收到错误＆＃39; ORA-01008：并非所有变量都绑定了＃39;这很有趣，因为当我将第8行的TEAM_SELECTOR改为＆＃39; MYSQL＆＃39; （这是一个团队名称）然后这段代码可以正常工作。请注意：TEAM_SELECTOR也在返回的查询中使用而没有问题。我也在使用APEX 5。

    DECLARE
        v_time INT;
        v_start_time int;
        v_end_time int;
        v_rownum int := 1;
        v_max_shifts int;
        v_location INT;
        v_P4_team_selector varchar2(30) := :TEAM_SELECTOR;
BEGIN

    select extract(hour from CAST(sysdate AS TIMESTAMP)) into v_time from dual;

    select count(*) into v_max_shifts from oncall_shift
        where team = v_P4_team_selector;

    FOR i IN 0..v_max_shifts
    LOOP

            select start_time into v_start_time from (select * from oncall_shift where team =v_P4_team_selector)
        where rownum = v_rownum;
            select end_time into v_end_time from (select * from oncall_shift where team =v_P4_team_selector)
        where rownum = v_rownum;
        v_rownum := v_rownum + 1;   

        if v_time >= v_start_time and v_time <= v_end_time
        then

                select location into v_location from oncall_shift
            where team = v_P4_team_selector
            and start_time = v_start_time
            and end_time = v_end_time;

            return '
                    SELECT E.FNAME "First Name",E.LNAME "Last Name",E.OFFICE_NUM "Office Number", E.MOBILE_NUM "Mobile Number",L.NAME Location, o.position "Primary/Secondary"
                FROM EMPLOYEE E, LOCATION L, ON_CALL O
                WHERE E.ID = O.EMP_ID
                AND L.ID = O.LOC_ID
                AND O.ONCALL_DATE=TRUNC(SYSDATE)
                AND O.TEAM=:TEAM_SELECTOR
                AND L.ID = ' || v_location ||
                ' ORDER BY l.name asc
                ';  
            EXIT;

        END IF;

    END LOOP;

好的，所以我认为问题是基于函数的经典报告在主变量（TEAM_SELECTOR）能够被绑定之前执行，因此抛出错误。我的解决方案是将其更改为基于sql查询的正常经典报告，该查询在绑定主变量后运行，因为我需要一个单独的变量，我在该页面上使用相同的查询期望更改“v_location”创建一个P1_LOCATION项目到P1_LOCATION。现在在P1_LOCATION页面项目中，我将程序放到了获取位置。

P1_LOCATION代码：

    DECLARE
        v_time INT;
        v_start_time int;
        v_end_time int;
        v_rownum int := 1;
        v_max_shifts int;
        v_location INT;
        v_P4_team_selector varchar2(30) := :TEAM_SELECTOR;
BEGIN

    select extract(hour from CAST(sysdate AS TIMESTAMP)) into v_time from dual;

    select count(*) into v_max_shifts from oncall_shift
        where team = v_P4_team_selector;

    FOR i IN 0..v_max_shifts
    LOOP

            select start_time into v_start_time from (select * from oncall_shift where team =v_P4_team_selector)
        where rownum = v_rownum;
            select end_time into v_end_time from (select * from oncall_shift where team =v_P4_team_selector)
        where rownum = v_rownum;
        v_rownum := v_rownum + 1;   

        if v_time >= v_start_time and v_time <= v_end_time
        then

                select location into v_location from oncall_shift
            where team = v_P4_team_selector
            and start_time = v_start_time
            and end_time = v_end_time;

            APEX_UTIL.set_session_state('P1_LOCATION',v_location);

            EXIT;

        END IF;

    END LOOP;
END;

经典报告（sql查询）：

SELECT E.FNAME "First Name",E.LNAME "Last Name",E.OFFICE_NUM "Office Number", E.MOBILE_NUM "Mobile Number",L.NAME Location, o.position "Primary/Secondary"
                FROM EMPLOYEE E, LOCATION L, ON_CALL O
                WHERE E.ID = O.EMP_ID
                AND L.ID = O.LOC_ID
                AND O.ONCALL_DATE=TRUNC(SYSDATE)
                AND O.TEAM=:TEAM_SELECTOR
                AND L.ID = :P1_LOCATION
                 ORDER BY l.name asc

Apex ORA-01008：并非所有变量都绑定在主变量上
