- SQL code
[code=SQL][code=SQL]现在用存储过程参数带过来的字符为"csdn是最大的程序员大本营" 怎样把它们一个一个拆分开来成这样? select * from csdn where name like '%csdn% 'or name like '%是% 'or name like '%最% 'or name like '%大% 'or name like '%的% 'or name like '%程% 'or name like '%序% 'or name like '%大% 'or name like '%本% ' or name like '%营% 'SQL codeCREATE FUNCTION fn_Split(@sText varchar(8000), @sDelim varchar(20) = ' ')RETURNS @retArray TABLE (idx smallint Primary Key, value varchar(8000))ASBEGINDECLARE @idx smallint,@value varchar(8000),@bcontinue bit,@iStrike smallint,@iDelimlength tinyintIF @sDelim = 'Space'BEGINSET @sDelim = ' 'ENDSET @idx = 0SET @sText = LTrim(RTrim(@sText))SET @iDelimlength = DATALENGTH(@sDelim)SET @bcontinue = 1IF NOT ((@iDelimlength = 0) or (@sDelim = 'Empty'))BEGINWHILE @bcontinue = 1 BEGIN--If you can find the delimiter in the text, retrieve the first element and--insert it with its index into the return table.

'csdn是最大的程序员大本营'
我今天要分'cs'
明天分'csd'
后天分'dn'
你这个能做到?
