In my case (not being an administrator, or maybe it's just our new SQL 2005 database) the master.sys.columns only has 44 rows, and the query only supplies 85,184 rows (44 cubed).
If it had only 3 more rows it would have reached the 100,000 mark.
But using the INFORMATION_SCHEMA.COLUMNS view with 4140 rows worked fine, and would give up to 70,000,000,000 consecutive numbers.

Oh, be careful, now...

That's why I use sys.all_columns. Even on a brand new instance, it contains more than 4,000 rows when all features are installed correctly and it doesn't matter which database is the current database so long as you have the necessary privs.

INFORMATION_SCHEMA.COLUMNS, on the other hand, can have zero rows in it on a new database and certainly a whole lot less than 4,000 rows.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

This is actually pretty cool. It's a great lesson on the use of ROW_NUMBER and OVER which I rarely get a chance to use.
