    <p>I have a file that contains SQL commands for the creation of a database.</p> <p>I also have a set of seperate files, each of which contain SQL commands for creating functions. For example:</p> <ul> <li>funcs_algebra.sql</li> <li>funcs_trigonometry.sql</li> <li>funcs_geometry.sql</li> </ul> <p>Lets say my main SQLscript looks like this:</p> <pre><code>CREATE DATABASE mydb; CREATE TABLE foo(id INT, name VARCHAR(32)); CREATE TABLE foobar(id INT, age REAL); -- Commands below to import the functions in the separate files -- funcs_algebra.sql -- funcs_trigonometry.sql -- funcs_geometry.sql </code></pre> <p>I want to know how to include the files in my 'main SQL' so that I have only one file to pass to psql.</p> <p>The objective is to be able to use psql to create the database (complete with functions) by merely passing the commands in this file to psql.</p> <p>Anyone knows how?</p> <p><strong>[Edit]</strong></p> <p>I probably should have stated what I thought was obvious. I want to keep the function related SQL in SEPARATE files so that I have only one source to modify. It is a way of me partitioning logic and keeping things <a href="http://en.wikipedia.org/wiki/Don%27t_repeat_yourself" rel="nofollow">DRY</a>.</p> <p>The function definitions are used for creating other template databases - so I want to keep them in separate files, but reference the files from within my SQL script.</p> <p>The only other way I can think of doing this is writing a bash script that makes successive calls to psql - first create the database, and then add the functions - not very elegant, and not very DRY. Is there another (more elegant) way?</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.
