SqlServer如何判断字段中是否含有汉字?
--/* --unicode编码范围: --汉字:[0x4e00,0x9fa5](或十进制[19968,40869]) --数字:[0x30,0x39](或十进制[48, 57]) --小写字母:[0x61,0x7a](或十进制[97, 122]) --大写字母:[0x41,0x5a](或十进制[65, 90]) --根据编码范围来判断 --*/ --创建 create proc p_A_VIC as declare @count int declare @i int declare @text nvarchar(50) set @i = 0 set @count = (select COUNT (*) from table ) while(@i < @count ) begin set @i +=1 --sid代表有一定循环规律的,若是无序的可以添加一个序列(Row_Number() OVER ---)。 --select * from (SELECT *, Row_Number() OVER ( ORDER BY [sid] ) num FROM s--table ) as s where num = 3 set @text = (select a from table where [sid] = @i) if unicode(@text) between 19968 And 40869 or unicode(@text) between 97 And 122 or unicode('a') between 65 And 90 begin print 0 end else print @text end --执行 exec p_A_VIC
实例1:
---由于某些原因HouseName 字段存入了GUID,为了区分 SELECT HouseName FROM ZSGYTD_HouseInfo SELECT HouseName FROM ZSGYTD_HouseInfo WHERE UNICODE(HouseName) BETWEEN 19968 AND 40869
执行结果:
实例2:
----将上述存入ZSGYTD_Estate 表ID的houseName进行左连接,获取到对应的Name SELECT h.HouseName, CASE WHEN UNICODE(h.HouseName) BETWEEN 19968 AND 40869 then h.HouseName ELSE e.Name END housename2 FROM ZSGYTD_HouseInfo h LEFT JOIN ZSGYTD_Estate e ON CONVERT(varchar(50),e.ID)=h.HouseName and e.IsDeleted=0 select*from ZSGYTD_Estate
执行结果:
