在这个我传递的 IGMT 是使用我们的日期函数在 php 页面中计算的，我希望在存储过程中使用这个值。

但是当我在 php 页面上执行它时，我得到一个错误：

存储过程中未定义的变量 IGMT。

有没有办法在这个存储过程中传递这个值？提前致谢..

您正在过程中构建一个 sql 语句，然后准备和执行它。问题是您在准备好的查询中使用文本“iGMT”而不是变量包含的值。

您需要将其换成占位符 (?) 并将 iGMT 参数传递到执行语句中。因此，例如第一个查询将变为

SET @Query = "SELECT Username, Sender, Mobile, 
        Type,
        CASE
        WHEN Type = 'TEXT' OR Type = 'FLASH' THEN
            Message
        WHEN Type = 'UNICODE' OR Type = 'UNICODE-FLASH' THEN
            CONVERT( UNHEX(Message) USING utf8)
        ELSE
            Message
        END AS Message, Length, MessageId,
        IFNULL((SELECT Status FROM DLRStatus WHERE MessageId = a.MessageId),IF((DATE(SentAt)=CURRENT_DATE),'ENQUEUE','ACCEPTD')) as Status,
        CONVERT_TZ(SentAt,?,G) FROM SmscLog a WHERE Username IN ( SELECT Username FROM Customers WHERE ResellerId = ? ) 
        AND DATE(SentAt) BETWEEN ? AND ? ORDER BY SentAt DESC";

SET @DistributorId = UId;
SET @SentFrom = dtFrom;
SET @SentTo = dtTo;
SET @Lim = CONCAT(' LIMIT ', OFFSET, ROWCOUNT);
SET @Query = CONCAT(@Query, @Lim);

PREPARE Stmt FROM @Query;
EXECUTE Stmt USING @iGMT, @DistributorId, @SentFrom, @SentTo;

您需要对过程中的每个语句进行此更改
