Tables getting dropped when new table imported

[Tog Porter]

Hello.

I am new to MySQL. I have a website with 1&1.co.uk and it includes a MYSQL database accessed via PHPMyadmin in plesk.

The database has 10 tables in it. When I import a new table the system adds it but also drops the other 9 tables.

I then have to re-import the other tables one by one. That works, but it is a lengthy workaround. I think the problem is that the new table is larger than the max allowed and this is somehow causing the other tables to be dropped.

Does anyone know how I can increase the maximum size of a database that can be imported, or could there be another reason that the other tables are getting dropped when I import the new one?

I am importing each table using a zip file.

Many thanks in advance.
