Question

在我的代码中，我将一个字符串变量（＆＃39; 4,5,6＆＃39;）传递给我的存储过程，该存储过程从该字符串（4,5,6-Name）中展开。我在存储过程中使用IN子句，我知道IN子句接受（＆＃39; 4＆＃39;，＆＃39; 5＆＃39;，＆＃39; 6＆＃39;）或简单地（4,5， 6）这种类型的数据，但我无法在我的存储过程中使用它。如果有任何其他方法可以帮助我。

CREATE DEFINER = 'root'@'localhost'
PROCEDURE kbm.report_site_transfer(IN siteid VARCHAR(50), IN datefrom VARCHAR (15), IN dateto VARCHAR (15))

SELECT
        * 
      FROM
        tbl_transfer
      WHERE
        tbl_transfer.siteNameID IN (siteid) AND (tbl_transfer.paymentDate BETWEEN datefrom AND dateto);

Answer 1

您是否曾尝试过类似的内容，因为我为您提供了链接 - 您将整个查询创建为字符串＆amp;然后作为准备好的声明执行：

CREATE DEFINER = 'root'@'localhost'
PROCEDURE kbm.report_site_transfer(IN siteid VARCHAR(50), IN datefrom VARCHAR (15), IN dateto VARCHAR (15))

Set @query = CONCAT("SELECT * FROM tbl_transfer WHERE tbl_transfer.siteNameID IN (", siteid, ") AND (tbl_transfer.paymentDate BETWEEN ", datefrom, " AND ", dateto, ")";

PREPARE stmt FROM @query;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

如果你想要单引号版本，你可以使用它：

Set @query = CONCAT("SELECT * FROM tbl_transfer WHERE tbl_transfer.siteNameID IN ('", REPLACE(siteid,",", "','"), "') AND (tbl_transfer.paymentDate BETWEEN ", datefrom, " AND ", dateto, ")";

Answer 2

此代码也正常工作。我使用了FIND_IN_SET函数：

FIND_IN_SET(tbl_transfer.siteNameID, siteid)

完整代码：

CREATE DEFINER = 'root'@'localhost'
PROCEDURE kbm.report_site_transfer(IN siteid VARCHAR(50), IN datefrom VARCHAR (15), IN dateto VARCHAR (15))

SELECT
    * 
  FROM
    tbl_transfer
  WHERE
FIND_IN_SET(tbl_transfer.siteNameID, siteid)  AND (tbl_transfer.paymentDate BETWEEN datefrom AND dateto);

如何在存储过程mysql的IN子句中使用字符串
