Alter DATABASE

Hello jsut a quick question...
Is it possible to alter the DATABASE structure after it is CREATED AND
POPULATED WITH RECORDS.
For example RENAME fields, Change datatypes etc...
If not what is the best way of doing it and then restore my data?

I use MySQL - MyISAM tables
Thanks!!!

Yes, ALTER TABLE can do a lot of changes like this. Subject to
limitations that you might expect, for example what should it do with
data if you change a VARCHAR(100) to a VARCHAR(6), or for that matter to
an INTEGER?

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)

Then twice this week I needed to add a column to a large table (about a million records). The tables...

Hi. I have a database I need to supply something (I'm assuming a t-sql script.. maybe something else is better) to update customer tables with. The operations include mostly changing varchar lengths, though a couple of columns were renamed. I'd like to maybe figure out how to get Enterprise Manager or Query Analyzer to generate the scripts.

Hello, I have an SQL Server 2005 database that I'm trying to create using script. Everything works fine, but when I click on "Database Diagrams" I get an error message that there is no database owner, and of course when I show the Database Properties, the database was created without one. Is there any way to ALTER AUTHORIZATION to a default owner or system administrator, something valid? Any direction would be appreciated.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
