    <p>I'm using Elixir in a project that connects to a postgres database. I want to run the following query on the database I'm connected to, but I'm not sure how to do it as I'm rather new to Elixir and SQLAlchemy. Anyone know how?</p> <p><code>VACUUM FULL ANALYZE table</code></p> <p><strong>Update</strong></p> <p>The error is: "UnboundExecutionError: Could not locate a bind configured on SQL expression or this Session". And the same result with session.close() issued before. I did try doing metadata.bind.execute() and that worked for a simple select. But for the VACUUM it said - "InternalError: (InternalError) VACUUM cannot run inside a transaction block", so now I'm trying to figure out how to turn that off.</p> <p><strong>Update 2</strong></p> <p>I can get the query to execute, but I'm still getting the same error - even when I create a new session and close the previous one.</p> <pre><code>from sqlalchemy import create_engine from sqlalchemy.orm import sessionmaker # ... insert stuff old_session.commit() old_session.close() new_sess = sessionmaker(autocommit=True) new_sess.configure(bind=create_engine('postgres://user:pw@host/db', echo=True)) sess = new_sess() sess.execute('VACUUM FULL ANALYZE table') sess.close() </code></pre> <p>and the output I get is </p> <pre><code>2009-12-10 10:00:16,769 INFO sqlalchemy.engine.base.Engine.0x...05ac VACUUM FULL ANALYZE table 2009-12-10 10:00:16,770 INFO sqlalchemy.engine.base.Engine.0x...05ac {} 2009-12-10 10:00:16,770 INFO sqlalchemy.engine.base.Engine.0x...05ac ROLLBACK finishing failed run, (InternalError) VACUUM cannot run inside a transaction block 'VACUUM FULL ANALYZE table' {} </code></pre> <p><strong>Update 3</strong></p> <p>Thanks to everyone who responded. <strike>I wasn't able to find the solution I wanted, but I think I'm just going to go with the one described here <a href="https://stackoverflow.com/questions/1017463/postgresql-how-to-run-vacuum-from-code-outside-transaction-block">PostgreSQL - how to run VACUUM from code outside transaction block?</a>. It's not ideal, but it works.</strike></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.

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