First see following function:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[Split](@String varchar(8000), @Delimiter char(1))
returns @temptable TABLE (items varchar(8000))
as
begin
declare @idx int
declare @slice varchar(8000)
select @idx = 1
if len(@String)<1 or @String is null return
while @idx!= 0
begin
set @idx = charindex(@Delimiter,@String)
if @idx!=0
set @slice = left(@String,@idx - 1)
else
set @slice = @String
if(len(@slice)>0)
insert into @temptable(Items) values(@slice)
set @String = right(@String,len(@String) - @idx)
if len(@String) = 0 break
end
return
end
GO
We can use it to find what you want:
create procedure FindSkilledPeople
@skillstolook nvarchar(100)
as
begin
SELECT name,skills,area FROM SkilledPeople, (select items from dbo.Split(@skillstolook,',')) as look
where items in (select items from dbo.Split(SkilledPeople.skills,','))
group by name,skills,area
having count(*)=(select count(*) from dbo.Split(@skillstolook,','))
end
In english: list all people who has all skills I am looking for
PS: this is not enough if you need ranking in skills (eg. A,B != B,A)
