我正在尝试将条件附加到 where 子句。但包含条件的字符串不起作用。我没有收到任何错误，但条件未完全应用于查询

这是查询。我将 CLINIC_ID 和 taleEnd 传递给我的存储过程。taleEnd 将包含一个或更多类似的条件 - “和 DOS 在 '2011-09-08' 和 '2011-10-08' 之间”

SELECT *
  FROM A
  JOIN B ON C.CLINIC_ID = VP.CLINIC_ID AND C.CLAIM_ID = VP.CLAIM_ID
  JOIN C ON P.CLINIC_ID = VP.CLINIC_ID  AND P.PATIENT_ID = VP.PATIENT_ID
  JOIN D ON I.CLINIC_ID = C.CLINIC_ID  AND I.INSURANCE_ID= C.PRIMARY_INSURANCE_ID
  JOIN E ON B.CLINIC_ID = I.CLINIC_ID  AND B.BUSINESS_ID= I.COMPANY_ID
 WHERE (VP.STATUS = 3 OR VP.STATUS = 5)
   AND VP.PRIMARY_PAID = 0
   AND VP.PRIMARY_PENDING > 0
   AND C.PRIMARY_PAYER_ID > 0
   AND C.HIDEN = 0
   AND VP.CLINIC_ID = CLINIC_ID + taleEnd

问题是，当我运行存储过程时，只应用了 Clinic_id 而不是 DOS。我尝试了 concat ，设置但没有任何效果。我没有收到任何错误，但结果不适用于 DOS。请任何人帮助我。

@Devart 这是存储过程。

CREATE DEFINER=`root`@`%` PROCEDURE `PRIMARY_INSURANCE_AGING`(CLINIC_ID INT,taleEnd TEXT)
BEGIN
DROP TEMPORARY TABLE IF EXISTS PRIMARY_TEMP;
CREATE TEMPORARY TABLE PRIMARY_TEMP
SELECT *     
  FROM A   
  JOIN B ON C.CLINIC_ID = VP.CLINIC_ID AND C.CLAIM_ID = VP.CLAIM_ID   
  JOIN C ON P.CLINIC_ID = VP.CLINIC_ID AND P.PATIENT_ID = VP.PATIENT_ID   
  JOIN D ON I.CLINIC_ID = C.CLINIC_ID  AND I.INSURANCE_ID= C.PRIMARY_INSURANCE_ID   
  JOIN E ON B.CLINIC_ID = I.CLINIC_ID  AND B.BUSINESS_ID= I.COMPANY_ID 
 WHERE (VP.STATUS = 3 OR VP.STATUS =5 ) 
   AND VP.PRIMARY_PAID = 0   
   AND VP.PRIMARY_PENDING > 0   
   AND C.PRIMARY_PAYER_ID > 0   
   AND C.HIDEN = 0  
   AND VP.CLINIC_ID = CLINIC_ID + taleEnd;

   END

这是Prepare语句的用法

SET @A = CONCAT(34847," and DOS between '2011-09-08' and '2011-10-08'");
PREPARE STMT FROM '
SELECT *
  FROM A
  JOIN B ON C.CLINIC_ID = VP.CLINIC_ID AND C.CLAIM_ID = VP.CLAIM_ID
  JOIN C ON P.CLINIC_ID = VP.CLINIC_ID AND P.PATIENT_ID = VP.PATIENT_ID
  JOIN D ON I.CLINIC_ID = C.CLINIC_ID AND I.INSURANCE_ID= C.PRIMARY_INSURANCE_ID
  JOIN E ON B.CLINIC_ID = I.CLINIC_ID AND B.BUSINESS_ID= I.COMPANY_ID
  WHERE (VP.STATUS = 3 OR VP.STATUS = 5)
  AND VP.PRIMARY_PAID = 0
  AND VP.PRIMARY_PENDING > 0
  AND C.PRIMARY_PAYER_ID > 0
  AND C.HIDEN = 0
  AND VP.CLINIC_ID ? ';

EXECUTE STMT USING @A;

如果您要传入CLINIC_ID存储过程，并尝试在过程中使用它，我认为（无法正确检查），变量CLINIC_ID和字段之间存在混淆VP.CLINIC_ID。

尝试将过程中的变量名称更改为唯一的名称。

同意 Dave Rix 关于变量和字段名称的看法，它们应该不同。

如果你想在查询中附加额外的字符串（比如 -和 '2011-09-08' 和 '2011-10-08' 之间的 DOS），那么你应该使用准备好的语句。

编辑：

例子：

SET @query = 'SELECT *
FROM A
JOIN B ON C.CLINIC_ID = VP.CLINIC_ID AND C.CLAIM_ID = VP.CLAIM_ID
JOIN C ON P.CLINIC_ID = VP.CLINIC_ID AND P.PATIENT_ID = VP.PATIENT_ID
JOIN D ON I.CLINIC_ID = C.CLINIC_ID AND I.INSURANCE_ID= C.PRIMARY_INSURANCE_ID
JOIN E ON B.CLINIC_ID = I.CLINIC_ID AND B.BUSINESS_ID= I.COMPANY_ID WHERE (VP.STATUS = 3 OR VP.STATUS =5 ) AND VP.PRIMARY_PAID = 0
AND VP.PRIMARY_PENDING > 0
AND C.PRIMARY_PAYER_ID > 0
AND C.HIDEN = 0
AND VP.CLINIC_ID = ?'; -- ? will be supplied with procedure argument clinic_id_value; where clinic_id_value is a renamed procedure argument

IF taleEnd IS NOT NULL THEN
  @query = CONCAT(@query, ' ', taleEnd);
END IF;

SET @clinic_id_value = clinic_id_value; -- copy procedure argument to the local variable
PREPARE STMT FROM @query;
EXECUTE STMT USING @clinic_id_value;
DEALLOCATE PREPARE STMT;
