dumpview

Category:

Database

Description:

Just a simple script to dump the source for an Oracle view.

The script reads the TEXT field from DBA_VIEWS, but first has to determine how long the field is since Oracle defines this column as a LONG.

Pretty simple quick hack, but people I work with have found it helpful.

Note: I'm using O/S authentication with a user who has DBA privs when I run this. If you're familiar with the DBI, you should be able to make appropriate changes to work for you.
