texte = 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]IDNAME1      Scott2      Rusty3      David4      Daniel5      Dustin[/writefile][search db=addfields_test.db&neIDdata=[blank]&rank=off][founditems][ID] - [NAME][/founditems][/search]

Results:1 - Scott2 - Rusty3 - David4 - Daniel5 - DustinNow, 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@com&PHONE=12-1235[/addfields][search db=addfields_test.db&neIDdata=[blank]&rank=off][founditems][ID] - [NAME] - [EMAIL] - [PHONE][/founditems][/search]

Results:1 - Scott - us@com - 12-12352 - Rusty - us@com - 12-12353 - David - us@com - 12-12354 - Daniel - us@com - 12-12355 - Dustin - us@com - 12-1235

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

[addfields] will not add more than 4 fields at one time; in the following example, the "fifth" field will not be added

[addfields db=test.db]address=[blank]&website=[blank]&brochure=[blank]&Home=[blank]&fifth=[blank][/addfields]

[deletefields] feature has been added in version 8.6 [deletefields db=test.db&fieldnames=column1,column4]
