How do I generate random number for each row in a TSQL Select?

Question

I need a different random number for each row in my table. The following seemingly obvious code uses the same random value for each row.

SELECT table_name,          


        

Answer 1

Update my_table set my_field = CEILING((RAND(CAST(NEWID() AS varbinary)) * 10))

Number between 1 and 10.
