MS SQL 2008 Studio创建语法错误

我有一个动态创建查询字符串的项目。不太复杂，只是复杂而已。我特别有一个问题添加到混合选择。当我保存视图时，Studio会添加一个as

在第一段代码的底部附近是SELECT MAXdate_PURED AS EJA_Date_PURED语句。这是我添加到视图中的新代码。我在“as”附近得到了无效语法并出错。如果我从maxdate中删除别名，则在保存视图时，studio将添加“as expr1”。如果我从select中删除别名，studio将在保存视图时添加“as expr1”

说实话，我不确定我在攻击正确获取最大日期的问题。

删除第二个“as”。即，删除“AS Date_Purchased_EJA”部分，并将其替换为“AS EJA_Date_Purchased”。实际上，应该只有第一个“AS”语句。然后在查询设计器窗口而不是视图设计器窗口中执行查询。代码如下所示

可能您已经在dbo.Users\u Info表中购买了EJA\u Date\u。我正在创建该列。从dbo.QEliteContacts中选择MAXdate\u purchased作为Expr1，其中contact\u id=dbo.Users.id作为Date\u purchased\u EJA，这是我执行时得到的结果，加上错误“无效列日期”\u Purchased\u EJA。是否尝试使用视图设计器窗口创建视图？？？如果尝试在查询设计器窗口中创建视图，则不会发生这种情况。它是一个现有视图，我正在尝试添加选择。我右键单击并单击“设计”。改为尝试在“查询设计器”窗口中使用ALTER VIEW语句。使用“视图设计器”窗口时，始终为聚合函数创建此额外的AS语句。因此，若要编辑视图，建议右键单击、脚本视图为、ALTER to、新建查询编辑器窗口？
