I created one dynamic SQL Server query to count the number of rows in a table. My aim is to list out the tables which have no records in a database. The query is as follows:
declare @strsql varchar(100)
declare @tablename varchar(50)
@tablename='table123'

@strsql='select count(*) from ' + @tablename

 exec(@strsql)
I am getting the output but I can't store this value in a variable for checking. I want to check like this:
/* @countvariable=0
print(@tablename)*/
If there is any other solution?

You can make your solution more flexible by grabbing the table names from the sysobjects table:
declare @strsql varchar(256)
create table #emptytables  (tablename varchar(128), table_rowcount int)

select @strsql='select distinct o.name as TableName, x.rowcnt as Table_RowCount
 from  sysobjects o
  inner join sysindexes x 
 on o.id = x.id 
 where x.rowcnt =  0 and
 o.type = ''U'''

insert #emptytables (TableName, Table_rowcount) exec (@strsql)
select * from #emptytables
drop table #emptytables
