sql server 在当前数据库查询 指定字符串,从而得出 该字符存在在 哪个表哪个字段

--select * from  sys.tables --获取当前数据库所有表
--select * from  sys.columns --获取当前数据库的所有字段

declare @str nvarchar(max)
set @str = '61'

create table #t_column(table_name nvarchar(max),column_name nvarchar(max))
insert into #t_column
select a.name as table_name,b.name as column_name
from sys.tables a,sys.columns b
where a.object_id = b.object_id
order by a.name

declare cur cursor for select * from #t_column
open cur
declare @table_name nvarchar(max),@column_name nvarchar(max)
fetch next from cur into @table_name,@column_name
while(@@FETCH_STATUS = 0)
begin
begin try
exec('if exists(select 1 from ' + @table_name + ' where ' + @column_name + ' = ' + '''' + @str + ''') ' + ' print ''' + @table_name + '''' +  ' + ''   ---   '' + ''' + @column_name + '''')
end try
begin catch
--print error_message()
end catch
fetch next from cur into @table_name,@column_name
end

close cur
deallocate cur
drop table #t_column
