第一步：创建 查询某个值存在某个表里的哪个字段的值里面 的存储过程
create proc spFind_Column_In_DB 
( 
    @type int,--类型：1为文字类型、2为数值类型 
    @str nvarchar(100)--需要搜索的名字 
) 
as
    --创建临时表存放结果 
    create table #tbl(PK int identity primary key ,tbl sysname,col sysname) 
    declare @tbl nvarchar(300),@col sysname,@sql nvarchar(1000) 
    if @type=1  
    begin
        declare curTable cursor fast_forward 
        for 
            select '['+SCHEMA_NAME(SCHEMA_ID)+'].['+o.name+']' tableName,'['+c.name+']' columnName from sys.columns c inner join sys.objects o on c.object_id=o.object_id 
            where o.type_desc='user_table' and user_type_id in (167,175,231,239,35,99) 
    end
    else
    begin 
        declare curTable cursor fast_forward 
        for 
        select '['+SCHEMA_NAME(SCHEMA_ID)+'].['+o.name+']' tableName,'['+c.name+']' columnName from sys.columns c inner join sys.objects o on c.object_id=o.object_id 
            where o.type_desc='user_table' and user_type_id in (56,48,52,59,60,62,106,108,122) 
    end
    open curtable 
    fetch next from curtable into @tbl,@col 
    while @@FETCH_STATUS=0 
    begin
        set @sql='if exists (select * from '+@tbl+' where '
        if @type=1 
        begin
            set @sql += @col + ' like ''%'+@str +'%'')'
        end
        else 
        begin
            set @sql +=@col + ' in ('+@str+'))'
        end
  
        set @sql += ' INSERT #TBL(tbl,col) VALUES('''+@tbl+''','''+@col+''')'
        --print @sql 
        exec (@sql) 
        fetch next from curtable into @tbl,@col 
    end
    close curtable  
    deallocate curtable 
    select * from #tbl

可能和它一起用的SQL语句：
查看与某一个表相关的视图、存储过程、函数
select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'
