你可以尝试这样
declare @searchstr varchar(max)
declare @valuestr varchar(max)
declare @index int
--结果表达试出现次数
declare @count int
--要搜索的表达式
set @searchstr = '111111abc2222222abc333333abc44444555'
--搜索表达试
set @valuestr = 'abc'
set @count = 0
select @index = charindex(@valuestr,@searchstr,0)
while @index0
begin
set @count = @count + 1
select @searchstr = substring(@searchstr,@index+len(@valuestr),len (@searchstr))
select @index = charindex(@valuestr,@searchstr,0)
end
select @count
要是表格里没有拼音的话不可能直接根据中文提取首字母的。EXCEL和SQL还没智能化到如此
