| Everybody, I've been doing a lot of on-line research and cannot find any reference to the exact problem I'm having. Let me preface this question with the fact that I'm coming from an Oracle background so my approach may not be the best way to tackle this. However, from the research I have done this approach seems reasonable. Also, I know about the undocumented procedure sp_MSforeachtable. That can give me a result similar to what I'm looking for but the format of the output is not what I need. Now the problem. I'm trying to write a reusable script to give me a list of all the tables in a database that have 1 or more rows. My approach is to a BAT file (see script 1 below) that calls OSQL twice, once to call a SQL script (see script 2 below) that uses the Information_Schema views to generate the SELECT COUNT(*) statements and fill in all the tables names in the database, write this to a temporary output file and the second OSQL command to read the temporary output file and generate me the results formatted the way I need. The result of the first OSQL run is correct EXCEPT for 1> 2> 3> 4> 5> 6> 7> 8> 9> 10> 11> 12> 13> garbage at the beginning of the file. Because of this garbage the 2nd OSQL command blows up! Anyone have any idea what is generating this garbage? If I manually edit out the garbage and then just run the 2nd OSQL command I get similar garbage in the final result file (see 2nd result file below). In Query Analyzer, when I run the GET_TABLE_COUNT.SQL Script manually then take its output and copy and paste it to a new query window and run that it works OK except for generating lots of blank lines where the result of the tables that have zero rows are. I am suppressing headings but am still getting the blank lines but at least it works! Any ideas anybody? Thanks For Any Help FYI -- SQL Server 2000 with SP3a.

| You can remove numbering with the '-n' OSQL parameter. However, you might consider using dynamic SQL to accomplish the task. Example below: SET NOCOUNT ON CREATE TABLE #TableRowCounts ( TableName nvarchar(261) NOT NULL, TableRowCount bigint NOT NULL ) DECLARE @TableName nvarchar(261), @SqlStatement nvarchar(500) DECLARE TableList CURSOR LOCAL FAST_FORWARD READ_ONLY FOR SELECT QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) AS TableName FROM INFORMATION_SCHEMA.TABLES WHERE OBJECTPROPERTY( OBJECT_ID( QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)), 'IsMSShipped') = 0 OPEN TableList WHILE 1 = 1 BEGIN FETCH NEXT FROM TableList INTO @TableName IF @@FETCH_STATUS = -1 BREAK SET @SqlStatement = N'INSERT INTO #TableRowCounts SELECT ''' + @TableName + N''', COUNT(*) FROM ' + @TableName + N' WITH (NOLOCK)' EXEC (@SqlStatement) END CLOSE TableList DEALLOCATE TableList SELECT * FROM #TableRowCounts WHERE TableRowCount > 0 ORDER BY TableName -- Hope this helps.

| Dan, Thanks for the answers. I completely missed the -n option in the BOL. I also like your alternative. Someone I work with suggested using a temporary table then just selecting what I want but your approach seems even more sophicated. I'm out of the office today so haven't had a chance to try either answer but will as soon as possible.
