Query: select empno,fname from dbo.Employees TABLESAMPLE SYSTEM (20 PERCENT) Error: Msg 102, Level 15, State 1, Line 3 Incorrect syntax near 'SYSTEM'. Are there any data base properties to be set to use this TABLESAMPLE ? Please reply this comment as i could not get the solution from long time. Regards, GK Hi Pinal,

When I copy your example and executed in Adventureworks Data base it is executed successfully But when I executed similar kind of query in my database “RND” it gives me error as it is posted by sudarsan earlier.

Query:
select empno,fname from dbo.Employees
TABLESAMPLE SYSTEM (20 PERCENT)

Error: Msg 102, Level 15, State 1, Line 3
Incorrect syntax near ‘SYSTEM’.

Are there any data base properties to be set to use this TABLESAMPLE ?

Please reply this comment as i could not get the solution from long time.

Like if anyone want to select 10 rows from table in random order. He can use select top 10 * from Table_Name order by newid() Hi Pinal,

I think for this you can use newid() function of sql server.

Like if anyone want to select 10 rows from table in random order. He can use

select top 10 * from Table_Name order by newid()
