sp_TableCounts

This is another secret weapon in my SSMS Query Shortcuts series. Sometimes the simple things are what we need to deliver best results as consultants. So if it is simple– we better be able to nail it on command when that client or manager is looking over your shoulder.

The faster, better way to get table row counts (and sizes)

SELECT COUNT(*) FROM SomeBigTable;

The tried and true way to get a rowcount. Also probably the worst way. Not that it is always a problem… but that is, in part, part of the problem. Exactly because it is not always an issue it can throw you off when it does cause one. Or worse, it hangs up production, blocking important stuff, while you’re off doing something else meantime. Sure, a NOLOCK may help and even a OPTION (MAXDOP 48) but there is still a better way and sp_TableCounts keeps it right at your fingertips.
