[Mark Scott]

Hi

Now do we have a debate about the worth of Wikipedia as a source of information?

Maybe another day.

:)

Subject: [Year 12 IT Apps] database convention - postcodes as a text field in databases

Hello All,

The link below pretty much says it all.

The convention is that postcodes should defined and be input as text.
Of course there could be circumstances in which a specialised database might need to use some 'regional intelligence' based on a postcode.

A mail drop to all postcodes between 3850 and 3860 covers my area of Gippsland for example. It saves time on listing 100's of towns in a complicated case or nested if statement.
