最近要准备复习,考MSSERVER2005,就是相关的SQL语句总结了下,一般常用的就没写了,都是一些可能会用到,不经常用,但是也并不是不用的语法,希望对大家有用 SQL语句 SELECT DISINCT(学号),等级= CASEWHEN 总学分50 THEN '及格'WHEN 总学分80 THEN '很好'ELS

最近要准备复习,考MSSERVER2005,就是相关的SQL语句总结了下,一般常用的就没写了,都是一些可能会用到,不经常用,但是也并不是不用的语法,希望对大家有用  SQL语句
SELECT DISINCT(学号),等级= CASE
							WHEN 总学分>50 THEN '及格'
							WHEN 总学分>80 THEN '很好'
							ELSE '优秀'
							END,    TOP(5) [PERCENT] INTO tb_name_other
					FROM tb_name CROSS JOIN tb_second_name
					WHERE th_colnum = 'xxxx' AND name LIKE '%王#_%' ESCAPE '#'
							AND major IN ('计算机','软件','通信')
							AND birthday NOT BETWEEN 'A' AND 'B'
							AND CONTAINS(*,'工程')
							AND FREETEXT(*,'作业')
					GROUP BY expression WITH CUBE /WITH ROLLUP
					HAVING expression
					ORDER BY expression
					COMPUTE COUNT(学号) BY 专业
					UNION ALL SELECT * FROM tb_third_name WHERE  学号='xxxx'
					EXCEPT/INTERSECT SELECT * FROM tb_forth_name WHERE 性别='1'(不能与COMPUTE 子句一起使用)
