Create Table with structure of another existing table

Create Table with structure of another existing table

Ok, this has many valid uses such as if you need to create backups or the ability to undo changes, you would want to create new tables with the same structure as another. Here is how you do it.
Also remember Indexes such as PRIMARY KEYS [b:7ed9581493]will not be preserved[/b:7ed9581493] so you will have to readd them manually.[/i:7ed9581493]

[code:1:7ed9581493]CREATE TABLE NewName AS SELECT * FROM TableStructureYouWantToCopy;[/code:1:7ed9581493]

Another way to do the same thing (although in MySQL 3.23 it doesn't work - probably version 4+ will support it) is:

[code:1:7ed9581493]CREATE TABLE NewName LIKE TableStructureYouWantToCopy[/code:1:7ed9581493]

[b:7ed9581493]Restore PRIMARY KEY[/b:7ed9581493]

As I mentioned above you will need to recreate any Indexes/PRIMARY KEYS

Here is an example of readding a PRIMARY KEY with an AUTO_INCREMENT field:

[b:7ed9581493]First make the field NOT NULL[/b:7ed9581493]


[b:7ed9581493]Create The Primary Key[/b:7ed9581493]
[code:1:7ed9581493]ALTER TABLE tableName ADD CONSTRAINT PRIMARY KEY(FieldName);[/code:1:7ed9581493]

[b:7ed9581493]ADD AUTO_INCREMENT[/b:7ed9581493]
[quote:7ed9581493]ALTER TABLE tableName MODIFY FieldNAME INT(18) NOT NULL AUTO_INCREMENT;[/quote:7ed9581493]

If there is an easier way then this then please let me know :)
