sql 谁遇到这么奇怪的问题 字符串截取
declare @location int
declare @temp nvarchar(100)
declare @temp1 nvarchar(100)
set @temp= N'周一001FL美通FL智星U31FL美服F30FL1.33FL4.75FL9.50'
set @location=charindex('FL',@temp)
while @location>0
begin
set @temp1= SUBSTRING(@temp,0,@location)
set @location=charindex('FL',@temp)
print @temp1
set @temp=substring(@temp,@location+2,len(@temp))
end
结果：
周一001
美通FL智
智星
美服F30
1.33F
4.75
9.50
怎么根据"FL" 提取出来
[解决办法]
顺序有问题，如下试试
declare @location int
declare @temp nvarchar(100)
declare @temp1 nvarchar(100)
set @temp= N'周一001FL美通FL智星U31FL美服F30FL1.33FL4.75FL9.50'
set @location=charindex('FL',@temp)
while @location>0
begin
set @temp1= SUBSTRING(@temp,0,@location)
print @temp1
set @temp=substring(@temp,@location+2,len(@temp))
set @location=charindex('FL',@temp)
if(charindex('FL',@temp)=0)
print @temp
end
