SQL - Insert Multiple Records into one tables at one time
How are you going to insert multiple records into a table at one time?
Here is the code you can do that:
Insert into Table
(Column1, Column2, Column3)
select Value01, Value02, Value03
Union ALL
select Value11, Value12, Value13
Union ALL
select Value21, Value22, Value23
It works and save time by avoiding multiple insert scripts.

Sometimes you may need to convert coordinates into different projection system. You can do this with GIS software. But you want to do it online, there is website for this task.

Envelope-free to deposit checks in ATM
Wachovia Bank now can deposit your check without envelopes. You do not have to even put the amount y0u are going to deposit. The ATM machine can read and scan checks and automatically know how much money that will be. You can deposit multiple checks at one time. It is very convenient. Then if you want a receipt, you did have a choice to get a receipt with scanned check images.
Not sure if the ATM machines in other banks have the same kind of features, I do find this new feature is very useful to customers.
