求解。。。在数据库:a的所有表所有列中查找其中一项="aaa"的所有表
------解决方案--------------------
--2008查找某数据库中的列是否存在某个值
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
--使用例子,查询库中存在aaa这个值的列:
exec spFind_Column_In_DB 1,'aaa'
------解决方案--------------------
declare @name nvarchar(100)
declare cur cursor for select name from sysobjects where type = 'U'
open cur
fetch next from cur into @name
WHILE @@FETCH_STATUS = 0
begin
declare @sql nvarchar(500),@s varchar(500)
set @s =''
set @sql='select @s=isnull(@s+''+'','''')+'''''',''''''+''+cast(''+name+'' as varchar)'' from syscolumns where id=object_id('''+@name+''') and xtype in(175,239,99,231,35,167) '
exec sp_executesql @sql,N'@s varchar(500) out',@s out
if len(@s) > 0
exec ('if exists(select 1 from (select '+ @s+' as col from ['+@name+']) b where charindex(''aa'',col)>0) print '''+@name+'''')
fetch next from cur into @name
end
close cur
DEALLOCATE cur
------解决方案--------------------
修改一下,应该能用
CREATE TABLE tb(id int,col varchar(20))
CREATE TABLE tb2(id int,data varchar(20))
INSERT tb VALUES(1,'中国');
INSERT tb VALUES(2,'liangck')
INSERT tb2 VALUES(1,'China')
GO
CREATE PROCEDURE dbo.FindString
@string NVARCHAR(100)
AS
DECLARE @SQL NVARCHAR(4000);
SET @SQL = N'
DECLARE @str NVARCHAR(4000);
SELECT
@str = ISNULL(@str + N'' OR '' + c.name + N'' LIKE N''''%'
+ @string + ' %'''''',
