Default problem with the INFORMATION_SCHEMA.COLUMNS

Hi

i have wrriten this code to find some values in the database but however it doesn't return any values on the
 --set nocount on
              select @res = coalesce( @res + ',' , '') + ' [' + COLUMN_NAME + ']'
                         FROM INFORMATION_SCHEMA.COLUMNS
                         WHERE TABLE_NAME = @columnnameT --AND COLUMN_NAME LIKE @columnnameT2 --AND COLUMN_NAME like '%[^_ID'
              Print @res
              Set @Params1 = N'Select ' + @res + 'from ['+ @tablename1 +'] where ID = ' + @fieldname1 + ''
              Print @res

My full script is...

CREATE TABLE #Results (i int identity, DBName varchar(450), TableName nvarchar(450), ColumnName nvarchar(450))
use master
go
--set quoted_identifier off
declare @columnnametosearch varchar(128)
declare @Databasetosearch varchar(128)
declare @query varchar(1000)
set @columnnametosearch ='uRALBase'
set @Databasetosearch = 'RALMMA'
set @query='set quoted_identifier off begin use end begin
 select db_name() as databasename,
 object_name(id) as Objectname,
 name as ColumnName from syscolumns
 where name like "'+@columnnametosearch+'%" and db_name() = "'+@Databasetosearch+'" end'
print @query
INSERT INTO #Results exec sp_MSforeachdb @query
SELECT DISTINCT TableName , ColumnName, DBName
FROM #Results

Select Count(*) as [Number of Tables] from #Results

USE RALMMA
Go
CREATE TABLE #Results1 (i int identity, Value int,BaseID int, Cu_Tbname varchar(450))
declare c cursor for select ColumnName,TableName from #Results
declare @fieldname varchar(450)
declare @tablename varchar(450)

open c
fetch next from c into @fieldname, @tablename
set @current_tablename = @tablename
while @@FETCH_STATUS = 0
 --set @current_tablename = @tablename
begin
  select @Params=N'@current_tablename nvarchar(100)'
  Set @current_tablename = @tablename
  set @sql = 'select [' + @fieldname + '],ID as [Base Table ID],@current_tablename as [Base Table Name] from [' + @tablename + '] '
  --exec sp_executesql @sql,@Params,@current_tablename
  INSERT INTO #Results1 exec sp_executesql @sql,@Params,@current_tablename --exec(@sql)
  --print @sql
  fetch next from c into @fieldname, @tablename
end

CREATE TABLE #FechResults (i int identity, Value int,RALBase nvarchar(50), BaseID int, Cu_Tbname varchar(450))
declare @Params1 nvarchar(500)

SELECT Count(*) as [Number of Rows]

open c1

fetch next from c1 into @fieldname1, @tablename1
while @@FETCH_STATUS = 0
begin
   Set @columnnameT = Rtrim(LTrim('''' + @tablename1 + ''''))
   Set @columnnameT2 = Ltrim(RTRIM('''' + '[' + SUBstring(+@tablename1,2,200)+ ']' + '_' + '%' + ''''))
     SET @SQLQQ = N'SELECT TOP 10 COLUMN_NAME
                        FROM INFORMATION_SCHEMA.COLUMNS

     --exec sp_executesql @SQLQQ --,@Params1,@columnnameT,@columnnameT2
     --print @SQLQQ

              --set nocount on
              select @res = coalesce( @res + ',' , '') + ' [' + COLUMN_NAME + ']'
                         FROM INFORMATION_SCHEMA.COLUMNS
                         WHERE TABLE_NAME = @columnnameT --AND COLUMN_NAME LIKE @columnnameT2 --AND COLUMN_NAME like '%[^_ID'

      exec sp_executesql @Params1 --,@Params1,@columnnameT,@columnnameT2
      print @Params1
     fetch next from c1 into @fieldname1, @tablename1
end

CLOSE c
DEALLOCATE c
CLOSE c1
DEALLOCATE c1
Drop TABLE #Results
Drop TABLE #Results1
Drop TABLE #FechResults
--Select * from uRALBase
