A well written “firehose” cursor will usually beat a well written Temp Table/While loop combination.

Yes, cursors are usually a bad thing and should be avoided but only if you can come up with a proper set-based solution. That goes for any form of RBAR including Temp Tables/While loops and recursive CTEs.

1. CTE
2. Loop
3. Temporary Tables
