is it possible to order the result of the data from within the sp_MSforeachdb in the attached code (thanks Scott), to be sorted by the count(*)?

example:
Database1 432
Database2 323
Database3 234 (Descending order)

thanks
EXEC sp_MSforeachdb '
IF ''?'' IN (''master'', ''model'', ''msdb'', ''tempdb'')
    RETURN
DECLARE @tableCount int
SELECT @tableCount = COUNT(*)
FROM [?].INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = ''BASE TABLE''
--...other conditions if you want them...
PRINT ''?, TableCount = '' + CAST(@tableCount AS varchar(10))
'

Not without a temp table

if OBJECT_ID('tempdb..#dbtablecount') is not null drop table #dbtablecount;
create table #dbtablecount (db sysname, tblcount int);
EXEC sp_MSforeachdb '
INSERT #dbtablecount (db, tblcount)
SELECT ''?'', COUNT(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = ''BASE TABLE''
  AND NOT ''?'' IN (''master'', ''model'', ''msdb'', ''tempdb'')
--...other conditions if you want them...
--PRINT ''?, TableCount = '' + CAST(@tableCount AS varchar(10))
';
declare @print varchar(max)
select @print=coalesce(@print+char(13)+char(10),'')
      + db + ', TableCount = ' + CAST(tblcount AS varchar(10))
from #dbtablecount;
drop table #dbtablecount;
print @print;

Correction


if OBJECT_ID('tempdb..#dbtablecount') is not null drop table #dbtablecount;
create table #dbtablecount (db sysname, tblcount int);
EXEC sp_MSforeachdb '

declare @print varchar(max)
select @print=coalesce(@print+char(13)+char(10),'')
      + db + ', TableCount = ' + CAST(tblcount AS varchar(10))
from #dbtablecount

Putting things back from the original query..


if OBJECT_ID('tempdb..#dbtablecount') is not null drop table #dbtablecount;
create table #dbtablecount (db sysname, tblcount int);
EXEC sp_MSforeachdb '
IF ''?'' IN (''master'', ''model'', ''msdb'', ''tempdb'')
    RETURN
INSERT #dbtablecount (db, tblcount)
SELECT ''?'', COUNT(*)
FROM [?].INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = ''BASE TABLE''
--...other conditions if you want them...
--PRINT ''?, TableCount = '' + CAST(@tableCount AS varchar(10))
';
declare @print varchar(max)
select @print=coalesce(@print+char(13)+char(10),'')
      + db + ', TableCount = ' + CAST(tblcount AS varchar(10))
from #dbtablecount
order by tblcount;
drop table #dbtablecount;
print @print;

For SQL Server 2000 (if the number of databases is ~> 200, which makes @print greater than the limit of varchar(8000).
set nocount on;
if OBJECT_ID('tempdb..#dbtablecount') is not null drop table #dbtablecount;
create table #dbtablecount (db sysname, tblcount int, rank int);
EXEC sp_MSforeachdb '
IF ''?'' IN (''master'', ''model'', ''msdb'', ''tempdb'')
    RETURN
INSERT #dbtablecount (db, tblcount)
SELECT ''?'', COUNT(*)
FROM [?].INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = ''BASE TABLE''
--...other conditions if you want them...
--PRINT ''?, TableCount = '' + CAST(@tableCount AS varchar(10))
';

update #dbtablecount
set rank=(select COUNT(*) from #dbtablecount b
	where #dbtablecount.tblcount>b.tblcount or
	(#dbtablecount.tblcount=b.tblcount and #dbtablecount.db>=b.db))
--select * from #dbtablecount order by tblcount

declare @print varchar(8000)
declare @max int select @max = MAX(rank) from #dbtablecount
declare @rank int set @rank=1
while @rank <= @max
begin
select @print= db + ', TableCount = ' + CAST(tblcount AS varchar(10))
from #dbtablecount
where rank=@rank;
print @print;
set @rank=@rank+1;
end;

drop table #dbtablecount;
