As discussed in previous tip which is TIP #33 we can get random result set by using NEWID function.
Now same can be achieve by using one more option which is called TABLESAMPLE.
We have following syntax for it
SELECT * FROM tableName TABLESAME (Number ROWS/PERCENT)
For example I am using same Adventureworks database and fetching top 10 records from Person table which should be different each time.
So, I will write following select query
SELECT TOP(10) FirstName,Lastname,MiddleName from Person.Person TABLESAMPLE(10 Percent)
OR
SELECT TOP(10) FirstName,LastName, MiddleName From Person.Person TABLESAMPLE(1000 Rows)
When , I run it I got following records.
So this is another a way of fetching random numbers.
Enjoy !!!
