SQL获取字段中的数字
作者:互联网
sql获取数字:只是将字符串中所有的数字组织在一起,比如“test12tt456”,返回的是12456
create function dbo.F_Get_Number (@S varchar(100))
returns int
AS
begin
while PATINDEX('%[^0-9]%',@S)>0
begin
set @s=stuff(@s,patindex('%[^0-9]%',@s),1,'')
end
return cast(@S as int)
end
Go
若是想从“test12tt456”取到12 和456两个数字,则为:
declare @str varchar(100),@tmp varchar(101),@i int
set @str='sddfd123fddfd56fddf78'
set @tmp=@str+'a'
while patindex('%[0-9]%',@tmp)>0
begin
set @i=1
while 1=1
begin
if isnumeric(substring(@tmp,patindex('%[0-9]%',@tmp)+@i,1))=0 break
set @i=@i+1
end
print substring(@tmp,patindex('%[0-9]%',@tmp),@i)
set @tmp=stuff(@tmp,patindex('%[0-9]%',@tmp),@i,'')
end
/*
123
56
78
*/
sql获取非数字:
create function dbo.F_Get_NANnumber (@S varchar(100))
returns varchar(500)
AS
begin
while PATINDEX('%[0-9]%',@S)>0
begin
set @s=stuff(@s,patindex('%[0-9]%',@s),1,'')
end
return @s
end
GO
