[解决办法]
查找某数据库中的列是否存在某个值

alter 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
