    <p>This is nice and easy to do, in fact, with the following command:</p> <pre><code>git tag --contains f414f31 </code></pre> <p>That will list all the tags such that <code>f414f31</code> is one of the tag's ancestors, or the tag itself points to that commit.</p> <p>This is particularly useful for finding which versions of <code>git</code> contain a particular feature :)</p> <hr> <p><em>Update:</em></p> <p>To answer a further question in the comment below:</p> <blockquote> <p>Is there any easy way to find out all the equivalent commits that may have been applied to separate branches?</p> </blockquote> <p>You can find a hash of the patch introduced by the commit by using <code>git patch-id</code> - that's the command that <code>git cherry</code>, <code>git rebase</code>, etc. use to find whether a commit has already been cherry-picked. So, if you want to find whether the change introduced by <code>f414f31</code> was also introduced by a commit on the branch <code>foo</code>, you could always use a short shell script something like:</p> <pre><code>patch_id () { git show $1 | git patch-id | cut -d ' ' -f1 } P=$(patch_id f414f31) git rev-list foo | while read C do P2=$(patch_id $C) if [ x$P = x$P2 ] then echo "Also introduced by commit $C" fi done </code></pre> <p>If you want to look across all branches, you can replace <code>foo</code> with <code>--all</code>. <a href="https://stackoverflow.com/users/119963/jefromi">Jefromi</a>'s comment below suggests a couple of other refinements, e.g. you can add a <code>break</code> if you want to stop looking after the first match (sensible if you're only searching a single branch), or exclude all ancestors of the original commit by using <code>git rev-list foo ^f414f31</code> instead.</p> <p>Jefromi's comment also reminds me that I should say a bit more about this approach. The <a href="http://schacon.github.com/git/git-patch-id.html" rel="nofollow noreferrer">documentation for <code>git patch-id</code></a> explains that the ID generated is "reasonably stable" - the line numbers and whitespace can change without affecting the ID, but if you had to fix any conflicts during the cherry-pick or rebase, you may end up changing the text of the patch. In that case, this wouldn't find the commit.</p> <p>I'm sure you can also do this with an invocation of <code>git cherry</code> somehow, but I can never remember which way round the arguments are meant to go... ;)</p>

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.
