Re: questions about merging
Might be a bit late, but on the naming issue: why not rename the tables on the old database before doing the dump? that would save you from potentially messing with your data due to parsing problems.

Re: questions about merging
then: dump, import locally, rename and dump again. Still feels a bit safer then parsing though it might be a bit more work.

Re: questions about merging
Robert, I know you have had other answers, but as to the database name, yes, you can remove the CREATE DATABASE statement and change the USE statement to the right database name. N.B. In our environment the students have only one database each, and will install blogs and wiki's etc. using that one db as the back end. Steve. On Wed, Jan 28, 2009 at 6:14 PM, Robert D.

Re: questions about merging
Robert, keep the two databases separated, that is on different mysql database (or schema as they are also called). If the wordpress blog is on a database named 'wpblog' for example import your dump in another newly created database. Could just use those statement in the dump file CREATE DATABASE `db169254900`; USE db169254900; it'll create and use a new database (logic separation / phisical different folders) You can have all the databases you want in MySQL, they are just logical separation between tables, and with MyISAM tables also phisical separation thru folders. cheers Claudio 2009/1/29 Robert D.

questions about merging
Hello all, I hope I get the terminology right. I am not sure merge is what I want, so let me describe what I need. I have a sql dump from a db that is a mediawiki. I cannot upgrade the software on the old server and need to move it to a new server. I have only one db available to me on the new server that currently holds a wordpress blog. As I understand it this should be no problem as long as the table names do not conflict, right? I know the command for restoring the db from the mysql command prompt. First, I want to make sure that doing mysql -p dbname dump.sql is not going to hose the current db. Next I want to find out if there is an easy way to change the table names. I need the tables prefixed with the wiki name. Can anyone help me to figure out the easiest and safest way to accomplish this? If any more information is needed I can get it for you, I'm sure. Thanks in advance for any help or pointers to relevant documentation, rdc -- Robert D.
