sql - 为什么不在postgresql中执行语句查询？

Question

我在通过触发器执行的函数中编写了以下查询。

SELECT report_date INTO logdate FROM agent_statistics WHERE agentid =             
    NEW.caller_id_name AND report_date = DATE(NEW.start_stamp);
SELECT COUNT(*) INTO outbound FROM cdr WHERE (caller_id_name = 
    NEW.caller_id_name AND direction = 'outbound' AND 
    DATE(NEW.start_stamp) = logdate);
SELECT COUNT(*) INTO consult FROM cdr WHERE (caller_id_name =
    NEW.caller_id_name AND direction = 'outbound' AND 
    DATE(NEW.start_stamp) = logdate AND billsec > '0');

这里，logdate 值给出了正确的日期。但是，outbound 和 consult 给出了表中的所有行。表示前一个日期还包括不包括的日期。我只需要当前日期的总行数。

替换你的DATE(NEW.start_stamp) = logdate);使用 start_stamp = logdate);
