Question

我有一个过程，它接受2个参数格式：

i_rule_type：＆＃39; val1＆＃39;，＆＃39; val2＆＃39;，＆＃39; val3＆＃39;

i_geo：＆＃39; val1＆＃39;，＆＃39; val2＆＃39;，val3＆＃39;

我知道他们正确进入，因为底部的if / else语句正常工作。当我对两个参数中的值进行硬编码或传入null时，查询可以正常工作。我可以说它在这种情况下正在运行，因为它需要一点时间才能完成并实际返回行。但是，当我传入参数时，它就像查询甚至没有运行一样 - 它立即完成并且没有任何错误就为空。我目前的怀疑是这些变量实际上并没有受到限制，但是我被卡住了。

PROCEDURE REPORT_PRC (i_rule_type IN VARCHAR2, i_geo IN VARCHAR2, results_out OUT sys_refcursor) IS

v_report_query    VARCHAR2(800);

BEGIN

v_report_query := 'SELECT r.NAME as RULE_NAME, r.DESCRIPTION as DESCRIPTION, r.RULE_ID as RULE_ID, r.AUDIENCE as RULE_TYPE, g.NAME as GEO, count(l.rule_id) as LEADS_ROUTED, max(l.LEAD_ASSIGNMENT_END) as LAST_ROUTED, a.NAME as ATTRIBUTE
FROM rule r
LEFT OUTER JOIN LEAD_DETAILED_LOG l on r.RULE_ID = l.RULE_ID
LEFT OUTER JOIN GEO g on r.GEO_ID = g.GEO_ID
LEFT OUTER JOIN RULE_ATTRIBUTE ra on r.RULE_ID = ra.RULE_ID
LEFT OUTER JOIN ATTRIBUTE a on ra.ATTRIBUTE_ID = a.ATTRIBUTE_ID';

if i_geo IS NOT NULL OR i_rule_type IS NOT NULL then 
    v_report_query := v_report_query || ' WHERE';
end if;

if i_rule_type IS NOT NULL then 
    v_report_query := v_report_query || ' r.AUDIENCE in (:i_rule_type)';
end if;

if i_geo IS NOT NULL then 
    if i_rule_type IS NOT NULL then
        v_report_query := v_report_query || ' AND';
    end if;
    v_report_query := v_report_query || ' g.NAME in (:i_geo)';
end if;

v_report_query := v_report_query || ' GROUP BY r.rule_id, r.NAME, r.DESCRIPTION, r.RULE_ID, r.AUDIENCE, l.RULE_ID, g.NAME, a.NAME ORDER BY r.NAME'; 

if i_geo IS NOT NULL AND i_rule_type IS NOT NULL then
    OPEN results_out FOR v_report_query USING i_rule_type, i_geo;
elsif i_geo IS NOT NULL then
    OPEN results_out FOR v_report_query USING i_geo;
elsif i_rule_type IS NOT NULL then
    OPEN results_out FOR v_report_query USING i_rule_type;
else
    OPEN results_out FOR v_report_query;
end if;

end REPORT_PRC;

PL / SQL过程不是将变量绑定到游标中
