自定义 sql Split函数 / 自定义mp_helptext查看存储

1. 分割函数：

    --Split 表函数将一个字符串按指定分隔符进行分割，返回一个表。
    create function split(
        @string varchar(255),--待分割字符串
        @separator varchar(255)--分割符
    )returns @array table(item varchar(255))
    as
    begin
        declare @begin int,@end int,@item varchar(255)
        set @begin = 1
        set @end=charindex(@separator,@string,@begin)
        while(@end<>0)
        begin
            set @item = substring(@string,@begin,@end-@begin)
            insert into @array(item) values(@item)
            set @begin = @end+1
            set @end=charindex(@separator,@string,@begin)
        end
        set @item = substring(@string,@begin,len(@string)+1-@begin)
        if (len(@item)>0)
            insert into @array(item) values(substring(@string,@begin,len(@string)+1-@begin))
        return
    end

2005 以上版本XQuery

create function func_splitid
(@str varchar(max),@split varchar(10))
RETURNS @t Table (c1 int)
AS
BEGIN
    DECLARE @x XML
    SET @x = CONVERT(XML,'<items><item id="' + REPLACE(@str, @split, '"/><item id="') + '"/></items>')
    INSERT INTO @t SELECT x.item.value('@id[1]', 'INT') FROM @x.nodes('//items/item') AS x(item)
    RETURN
END

执行结果:

2. mp_helptext

    create procedure mp_helptext(
        @name varchar(255)
    )
    as
    declare @object_id int,
                    @sourcecode varchar(max),
                    @line varchar(max),
                    @end int,
                    @rn varchar(2),
                    @tab varchar(1)  

    declare @source table(
        source varchar(max)
    )  

    set @rn = char(13)+char(10)
    set @tab = char(9)  

    select @sourcecode = definition from sys.sql_modules where object_id=object_id(@name)  

    while(charindex(@rn,@sourcecode)!=0)
    begin
        set @end=charindex(@rn,@sourcecode)
        set @line = replace(substring(@sourcecode,1,@end-1),@tab,@tab+@tab)
        if(charindex('create',@line)<>0 and (charindex('proc',@line)<>0 or charindex('view',@line)<>0 or charindex('function',@line)<>0 or charindex('trigger',@line)<>0))
        begin
            set @line = replace(@line,'create','alter')
        end
        insert into @source(source) values(@line)
        set @end = @end + 2
        set @sourcecode = substring(@sourcecode,@end,len(@sourcecode))
    end
    insert into @source(source) values(@sourcecode)  

    select * from @source
