Hi Everyone!
I've got a SQL Server table with about 50,000 rows in it. I want to select about 5,000 of those rows at random. I've thought of a complicated way, creating a temp
table with a "random number" column, copying my table into that, looping through the temp table and updating each row with RAND(), and then selecting from that table
where the random number column < 0.1. I'm looking for a simpler way to do it, in a single statement if possible.
This article suggest using the NEWID() function. That looks promising, but I can't see how I could reliably select a certain percentage of rows.
Anybody ever do this before? Any ideas?
Thanks in advance!
