我正在尝试运行一个SQL查询，其中包含一个MERGE INTO语句，它循环遍历每个月。
我收到了一些语法错误：
Msg 156，Level 15，State 1，Line 3关键字'INTO'附近的语法不正确。
消息156，级别15，状态1，行10关键字“AS”附近的语法不正确。
Msg 102，Level 15，State 1，Line 35'，'。附近的语法不正确。
正确打印月份/年，所以我认为问题不在循环中，而是在合并语句中。我环顾四周，但它看起来对我来说，但我确信我错过了一些东西。我本来可以发誓我之前使用过这段代码而且工作正常。
以下是代码：
Declare @StartDate As Datetime set @StartDate = '5/1/2015'; --Update to first month that needs to be added
Declare @StopDate As Datetime set @StopDate = '12/1/2015'; --Update to last month that needs to be added
Print 'Start Date ' + Cast(@StartDate as varchar(30));
Print 'Stop Date ' + Cast(@StopDate as varchar(30));
Print 'Total Months ' + Cast(Datediff(Month, @StartDate, @StopDate) + 1 as varchar(30));
Print ' ';
Declare @Date As Datetime set @Date = @StartDate;
Declare @SQL_Cmd As Varchar(Max);
Declare @SQL_Contract_Status As Varchar(Max) set @SQL_Contract_Status =
