我正在编写一个程序,以便从数据库中获取数据。
这是我的程序。
CREATE DEFINER=`root`@`localhost` PROCEDURE `getCdrListnew`(from_date DATETIME, to_date DATETIME,
p_category VARCHAR(255), p_callType VARCHAR(255), p_businessId VARCHAR(255), p_dnc VARCHAR(255),
p_cli VARCHAR(255), p_dni VARCHAR(255), p_callNumber VARCHAR(255), p_dialType VARCHAR(255), p_contractType VARCHAR(255) )
BEGIN
DECLARE a INT ;
DECLARE setFilter INT DEFAULT FALSE;
DECLARE CONTINUE HANDLER FOR NOT FOUND
SET a = 0;
BEGIN
END;
SET @sqlCalls = 'SELECT agentcdr.isdnCauseCode,COUNT(*) as count FROM cdr';
-- SET @sqlCalls= CONCAT(@sqlCalls,' LEFT JOIN agentcdr ON cdr.idCDR=agentcdr.cdr_idCDR ');
IF( (from_date IS NOT NULL AND from_date != '')&& (to_date IS NOT NULL AND to_date != '') ) THEN
SET @sqlCalls= CONCAT(@sqlCalls,' WHERE cdr.createdDt >=\'',from_date,'\' AND cdr.createdDT<=', '\'',to_date,'\'');
SET setFilter = TRUE;
END IF;
SET @sqlCalls= CONCAT(@sqlCalls,' LEFT JOIN agentcdr ON cdr.idCDR=agentcdr.cdr_idCDR GROUP BY agentcdr.isdnCauseCode ');
PREPARE prepsqlstr1 FROM @sqlCalls;
EXECUTE prepsqlstr1;
END
当我执行上面的代码时,我收到如下错误。
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LEFT JOIN agentcdr ON cdr.idCDR=agentcdr.cdr_idCDR GROUP BY agentcdr.isdnCauseCo' at line 1
我知道这是语法问题,但无法弄清楚我在这里做错了什么。
请帮帮我。
如果有任何方法可以打印出在调试过程中执行的查询,也可以告诉我。

在生成的语句中看起来订单错误:
你得到select ... where ... left join ...
。这是错误的语法。
