create function Split ( @StringToSplit varchar(2048), @Separator varchar(128)) returns table as return with indices as ( select 0 S, 1 E union all select E, charindex(@Separator, @StringToSplit, E) + len(@Separator) from indices where E > S ) select substring(@StringToSplit,S, case when E > len(@Separator) then e-s-len(@Separator) else len(@StringToSplit) - s + 1 end) String ,S StartIndex from indices where S >0 然後用下列方式取 select String from Split('22|23|34' , '|') group by string

結果：
