  SELECT * INTO 表1 FROM 表2

--SELECT * INTO [dbo].[AM_F_BusinessOperationMonthAMT] FROM [dbo].[AM_F_BusinessOperation]

INSERT INTO [dbo].[AM_F_BusinessOperationMonthAMT] SELECT * FROM [dbo].[AM_F_BusinessOperation] 

//在已知#table1203临时表结构时 可以将select出来union以后的数据插入到临时表中
INSERT INTO #table1203  SELECT   CAST( PlazaName  AS NVARCHAR) AS value  FROM dbo.AM_Assets UNION SELECT CAST( PlazaKey AS NVARCHAR) AS value FROM dbo.AM_Assets
