Seems that Oracle 9.2 (using MS ODBC driver) requires extra

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
and references other tables as well.
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

(one-to-one, one-to-many etc)
Anyways, long story short is i want to create a one-to-one relationship with

Hi!
I have a table with a column of BIGINT and I want to change the type to

Command ALTER TABLE TABLE1 ALTER COLUMN COL1 SET DATA TYPE SMALLINT

Keep in mind this is my first compiled SQL program Stored Procedure
(SP), copied from a book by Frasier Visual C++.NET in Visual Studio
2005 (Chap12). So far, so theory, except for one bug (feature?)
below. At some point I'm sure I'll be able to laugh about this, akin
to forgeting a semi-colon in C/C++, but right now it's frustrating
(time to sleep on it for a while).

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
