sql - How do I rename primary key values in Oracle? -

-

Our application uses an Oracle 10g database where many primary keys come in front of the end user, product code and such misfortune It is late in doing anything with it because there are so many reports and custom scripts that we do not have control. We can not redefine the primary key or mess up the database structure.

Now some customers want to change some primary key values. They initially wanted to call P23A1, now it should be called Cat 23 MOD 1 (not a real example, but you get my meaning.)

Is there an easy way to do this? I prefer a script that can be parametred to fit other tables and keys, but external equipment will be acceptable if there is no other way.

The problem is probably with foreign keys in terms of PK

  1. Settle the obstacles
  2. Modify the parent, in the form described in this Tom Kite article, you should define foreign keys as "instant in the beginning".
  3. Modify child values ​​
  4. Earn changes

Simple.

And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page. What it should do, send the values ​​of the form for Project_Azax.fp, then there will be a refund of success on the page which is correct or false. $ (document) .ready (function () {$ ('div # didIt').
