1、新表不存在（即复制数据的同时创建与旧表相同结构的新表）： SELECT * INTO dbo.test_backup FROM dbo.TP_TeacherSalaryPreviewHistory WHERE SemesterID=137 AND TrainingCenterID=13 AND (GradeCode BETWEEN 14 AND 16) AND SegmentID=2 AND SalaryDate ='2012-8'
2、新表已存在，从旧表从插入选择的数据（注意：表的[主键]不要复制，因为具有唯一性，否则：Sql Server提示“当 IDENTITY_INSERT 设置为 OFF 时，不能为表 'xxxxxx' 中的标识列插入显式值”）
INSERT INTO dbo.test_backup( [SemesterID] ,[SemesterName] ,[SegmentID] ,[SegmentName] ,[SalaryDate] ) SELECT [SemesterID] ,[SemesterName] ,[SegmentID] ,[SegmentName] ,[SalaryDate] FROM [dbo].[TP_TeacherSalaryPreviewHistory] WHERE SemesterID=137 AND TrainingCenterID=13 AND (GradeCode between 14 and 16) AND SegmentID=2 AND SalaryDate ='2012-8' AND (ClassCategoryID IN (167,192,91,191,192))
以上方法经过测试，全部通过！！
