    <p>I'm currently developing an application using a MySQL database.</p> <p>The database-structure is still in flux and changes while development progresses (I change my local copy, leaving the one on the test-server alone).</p> <p>Is there a way to compare the two instances of the database to see if there were any changes?</p> <p>While currently simply discarding the previous test server database is fine, as testing starts entering test data it could get a bit tricky.<br> The same though more so will happen again later in production...</p> <p>Is there an easy way to incrementally make changes to the production database, preferably by automatically creating a script to modify it? </p> <hr> <p>Tools mentioned in the answers:</p> <ul> <li><a href="https://www.red-gate.com/products/mysql/mysql-compare/" rel="nofollow noreferrer">Red-Gate's MySQL Schema &amp; Data Compare</a> (Commercial)</li> <li><a href="https://launchpad.net/percona-toolkit" rel="nofollow noreferrer">Maatkit (now Percona)</a></li> <li><a href="http://www.liquibase.org" rel="nofollow noreferrer">liquibase</a></li> <li><a href="http://www.quest.com/toad-for-mysql/" rel="nofollow noreferrer">Toad</a></li> <li><a href="http://nobhillsoft.com/NHDBCompare.aspx" rel="nofollow noreferrer">Nob Hill Database Compare</a> (Commercial)</li> <li><a href="http://adamspiers.org/computing/mysqldiff/" rel="nofollow noreferrer">MySQL Diff</a></li> <li><a href="http://www.sqledt.com" rel="nofollow noreferrer">SQL EDT</a> (Commercial)</li> </ul>

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
