Today I’ve wrote a simple script to get number of records for all tables in a database and fetch those tables that contains at least one record.
This picture shows an example of result set:
Here is the script:
declare @tempTable
table(tablename
varchar(max),
rowscount int,processed bit)
insert into @tempTable
select TABLE_NAME,0,0 from INFORMATION_SCHEMA.TABLES
where TABLE_CATALOG=‘DEMO’
declare
@currentTable varchar(max)
set
@currentTable=(select top 1 tablename from
@tempTable where processed=0)
declare
@sqlCommand nvarchar(500)
declare @rowsnum int
declare @param nvarchar(500)
set @param= N’@cnt int OUTPUT’;
while (select COUNT(*) from @tempTable where
processed=0)<>0
begin
set
@sqlCommand=N’select
@cnt=count(*) from ‘+@currentTable
EXECUTE sp_executesql @sqlCommand, @param, @cnt=@rowsnum OUTPUT;
update @tempTable
set processed=1,rowscount=@rowsnum
where tablename=@currentTable
set
@currentTable=(select top 1 tablename from
@tempTable where processed=0)
end
select tablename,rowscount from
@tempTable
where rowscount>0
order by rowscount desc
