I am using phpMyAdmin to create database tables and fields. I have 100's of tables in a single database. Now I need to make the same on few more servers.
I feel it's too hard to write SQL queries to create that database. Is there any reverse process to generate an SQL query file from phpMyAdmin or anyother tool? I want to create a database in a GUI, and I need the SQL query for my database. Is there any tool to generate it automatically?
If I understood you correctly, you want to export a database (with many tables) using phpMyAdmin, and then import it and use it on another server.
Yes. You can do that.
Select the database on the left-hand side in phpMyAdmin and then:
Export -> Select All Tables -> Adjust Options -> Go.
You are going to get <youdatabasename>.sql file, with all the table definitions inside. Then you can import it in another phpMyAdmin or other database handler.
You can use mysqldump to do this. Then --nodata switch should do what you want.

I am using the Data Export functionality to create a dump of a database in MySQL Workbench. Once I select the database, I want to select a subset of the tables on the right side in the screenshot. However, the list of tables is not displayed. How do I make a single-file dump of a subset of tables of a database?
Click on one row and you see the tables
It may sound dumb from me, but have you tried to click on the database choosen, not just check it.
Try to click the name of the database.
i've a MSSQL database and trying to migrate to MySQL database.. the problem is when I using MySQL WorkBench, some table records in my MSSQL database is not migrated (there is an error and MySQL Workbench not responding).. is there any tools to export MSSQL table records into SQL file that compatible to be executed in MySQL?
Both T-SQL and MySQL and support VALUES clause. So, right click on the database and select Generate scripts from Tasks:
Then you can choose objects:
and then make sure you have selected to get the data, too:
You can even get the schema and change it a little bit to match the MySQL syntax.
For small amount of data this is pretty cool. If you are exporting large tables it will be better to use another tool. For example, using bcp you can export your data in CSV format and then import it in the MySQL database.
I have a wordpress instance running on my localhost. In order to move this to another server, I'd like to export the contents of this database to an sql file. However, I don't have the permission to create new databases, I have an existing database in which I'd like to insert the tables and all the rows inside them. Is there a way to tell phpmyadmin to export the data in such a way that everything will be inserted into this new database? Or would it be better to just do a find/replace inside the sql file?
In fact, if you select the database in phpmyadmin, it shows all the tables contained. If you choose to export at that stage, it will export by default (actually depends on its version) all the tables structure and data without database creation. Additionally, it does give you the option of exporting only the data.
I have 2 active database connections, I need to replace a number of tables from 'connection1' with that of connection2. The structures may, or may not be same, (depending if we make changes to the connection1 table.
I would assume I should do a complete table dump and replace keys where neccesary, but I really have no idea how to do this :)
Any help?
Have a look at Schema and Data sync tools in dbForge Studio for MySQL. It will help you to compare two databases on different servers, map tables and fields, generate and run synchronization script.
I ended up using the build in system command in PHP and mysqldump to first dump the data (export) to a file, then used system() again with mysql to import it into the new table and replace the old one.
Works like a charm :)
I would like to select data from a second MySQL database in order to migrate data from one server to another.
I'm looking for syntax like
SELECT * FROM username:password#serverip.databaseName.tableName
Is this possible? I would be able to do this in Microsoft SQL Server using linked servers, so I'm assuming it's possible in MySQL as well.
You can create a table using FEDERATED storage engine:
CREATE TABLE tableName (id INT NOT NULL, …)
ENGINE=FEDERATED
CONNECTION='mysql://username:password#serverip/databaseName/tableName'
SELECT *
FROM tableName
Basically, it will serve as a view over the remote tableName.
There are generally two approaches you can take, although neither of them sound like what you're after:
Use replication and set up a master/slave relationship between the two databases.
Simply dump the data (using the command line mysqldump tool) from the 1st database and import it into the 2nd.
However, both of these will ultimately migrate all of the data (i.e.: not a subset), although you can specify specific table(s) via mysqldump. Additionally, if you use the mysqldump approach and you're not using InnoDB you'll need to ensure that the source database isn't in use (i.e.: has integrity) when the dump is created.
You can't do this directly, but as someone else alluded to in a comment, you can use mysqldump to export the contents of a table as a SQL script.
At that point you could run the script on the new server to create the table, or if more manipulation of the data is required, import that data into a table with a different name on the new server, then write a query to copy the data from there.
