I have a problem creating mySQL tables with PHP. I am making an app
where a user can create a project. Pressing "submit" on proj_form.php
goes to proj_add.php where a couple of things happen. The project's
meta information is put into a project table, mysql_insert_id() gets
the $proj_ID, and a table named that $proj_ID is created to hold all
of that project's tasks. Here is my code to create the table for a
project's tasks:

Seems that Oracle 9.2 (using MS ODBC driver) requires extra
parentheses when adding multiple columns to a table:
ALTER TABLE MyTable ADD (MyColumn1 VARCHAR(255), MyColumn2
VARCHAR(255))
vs
ALTER TABLE MyTable ADD MyColumn1 VARCHAR(255), MyColumn2 VARCHAR(255)

I need to change my primary key column type from smallint to int.
I have tried:
ALTER TABLE livegroup MODIFY id INT UNSIGNED NOT NULL AUTO_INCREMENT;
But get an error message certainly since my id-column is primary key

How can I come around this problem?
Need help

Just started learning SQL recently.
But one thing i'm still not clear on is about altering relationships between
tables after they've been created.
Instead of creating a foreign key when the table is first created - i create
the table and then run a query to set the foreign key and relationship
(one-to-one, one-to-many etc)
Anyways, long story short is i want to create a one-to-one relationship with

Hello!
I have a weird problem... The application I use issues this SQL from
time to time:

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

Hello
I'm a network technician in training and I need your help.
