MySql存储过程问题

SQL code

  
Create PROCEDURE USP_CreateLogTables(in Pointer datetime,in Counts int)
begin
    declare CountPointer int
    declare DateString    varchar(20)
    declare TableName varchar(50)
    declare ExecuteSQL varchar(50)
    declare SQLTxt varchar(max)
    
    Set CountPointer = Counts
    
    Set SQLTxt=' CREATE TABLE dbo.Tracker_Log(
        LogID bigint PRIMARY KEY  auto_increment NOT NULL,
        TrackerID varchar(50) NOT NULL,
        LogTime datetime NOT NULL,
        SessionId varchar(50) NOT NULL,
        PassportID bigint NULL,
        UserID bigint NULL,
        ClientIP varchar(64) NULL,
        ServerIP varchar(64) NULL,
        CurrentUrl varchar(255) NULL,
        ReferrerUrl varchar(255) NULL,
        ClickLinkUrl varchar(255) NULL,
        ClickLinkTitle nvarchar(200) NULL,
        CurrentClientTime datetime NULL,
        CurrentServerTime datetime NULL,
        ClientServerTimeDif bigint Null,
        ServerExecuteTime bigint NULL,
        NetTransTime bigint NULL,
        ServerResponseTime datetime NULL,
        ClientLoadTime bigint NULL,
        UserDwellTime bigint NULL
    )'

    While(CountPointer > 0)
        Begin
            Set DateString = Right(Cast(DateName(yyyy, Pointer) as varchar(4)), 2) + '_' +
                                Right('0' + Cast(Month(Pointer) as varchar(2)), 2) + '_' +
                                Right('0' + Cast(DatePart(day, Pointer) as varchar(2)), 2)

            Set TableName = 'Tracker_Log_' + DateString
            
            Select ExecuteSQL = Replace(SQLTxt, 'Tracker_Log', TableName)

            execute(ExecuteSQL)

            Set CountPointer = CountPointer - 1
            Set Pointer = DateAdd(dd, CountPointer, getDate())
        End

END

无论我怎么改，IDE都提示存在错误

我的MYSQL版本为5.0.67

之前是MSSQL的存储过程，今天刚接触MYSQL，死活调不通，还请大家指点。

假设你的SQL语句正确

execute(ExecuteSQL)->

set @asql=ExecuteSQL;

prepre tt from @asql;

execute tt;




语句后面怎么没有结束符号啊“;”

while 需要 end while 来结束！

WHILE i < count DO

……

END WHILE;

MySQL 和ＳＱＬ　ＳＥＲＶＥ有很多差别。

字符串合并不是用+号是用 concat 函数。
