[AddFields db=…]...WebDNA...[/AddFields]

The [AddFields] context adds new fields to an existing WebDNA database.

First, lets use the following code to create a new test database and run a simple search on the new database.

[closedatabase db=addfields_test.db]

[writefile file=addfields_test.db]ID,NAME
"1","Scott"
"2","Rusty"
"3","David"
"4","Daniel"
"5","Dustin"
[/writefile]

[search db=addfields_test.db&neIDdata=[blank]&rank=off]
[founditems]
[ID] - [NAME]

[/founditems]
[/search]

Results:

1 - Scott
2 - Rusty
3 - David
4 - Daniel
5 - Dustin

Now, lets use the [AddFields] context to add EMAIL and PHONE fields to the 'addfields_test.db' database, initializing the new field value with some arbitrary data. We will again perform a simple search on the same database to confirm that the new fields, and field data, have been added.

We use the following WebDNA code:

[AddFields db=addfields_test.db]EMAIL=us.here.com&PHONE=123-1235[/AddFields]

[search db=addfields_test.db&neIDdata=[blank]&rank=off]
[founditems]
[ID] - [NAME] - [EMAIL] - [PHONE]

[/founditems]
[/search]

Results:

1 - Scott - us.here.com - 123-1235
2 - Rusty - us.here.com - 123-1235
3 - David - us.here.com - 123-1235
4 - Daniel - us.here.com - 123-1235
5 - Dustin - us.here.com - 123-1235

Note that the [AddFields] context will not add fieldnames that already exist in the target database.
