Tracking information: (1) changes row count /insert,update,delete/; (2) changes IDENTITY value; (3) changes physical allocations /used pages/; (4) added new tables; (5) dropped tables. The batch must be initialized before using (at least once executed). I use this batch to […]

I was going through the painfull optimization of the database of creating better clustered indexes (not the default ones on the primary key).This operation was requiring removing all foreign keys to this table and then recreation them again.I created this script to optimize this quite tidious task.

The calculation of distance between two points using standard spherical geometry can be inaccurate for short distances (ten miles or less) because the sine function of very small angles approaches zero. The haversine approach (http://en.wikipedia.org/wiki/Haversine_formula) turns this around, so it is very accurate at small distances but has larger errors (about ten miles) for points […]
