How to count empty tables in database?

Question

Is there any way to count tables with no rows in my database with using T-SQL statement?

Answer 1

I use the following:

SELECT t.NAME AS TableName, sum(p.rows) as RowCounts
    FROM sys.tables t
INNER JOIN sys.indexes i
    ON t.OBJECT_ID = i.object_id
INNER JOIN sys.partitions p
    ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
WHERE
    i.name IS NULL AND i.index_id <= 1
GROUP BY 
    t.NAME, i.object_id, i.index_id, i.name 
HAVING SUM(p.rows) = 0

from khtan @ SQL Server Forums, this is used to drop all empty tables, maybe you could adapt it to output a count?

declare @name varchar(128), @sql nvarchar(2000), @i int
select  @name = ''
while   @name < (select max(name) from sysobjects where xtype = 'U')
begin
    select @name = min(name) from sysobjects where xtype = 'U' and name > @name
    select @sql = 'select @i = count(*) from [' + @name + ']'
    exec sp_executesql @sql, N'@i int out', @i out
    if @i = 0
    begin
        select @sql = 'drop table [' + @name + ']'
        print @sql
            -- unmask next to drop the table
        -- exec (@sql)
    end
end

I don't have SQLServer here but I could take a stab at it if you like.

There you go... using a derived table.

SELECT * FROM
(
 SELECT 
  [TableName] = so.name, 
  [RowCount] = MAX(si.rows) 
 FROM 
  sysobjects so, 
  sysindexes si 
 WHERE 
  so.xtype = 'U' 
  AND 
  si.id = OBJECT_ID(so.name) 
 GROUP BY 
  so.name 
) sub
WHERE sub.[RowCount] = 0
