<title>Using ij to run SQL scripts</title>
</head>
<body>
<h2>Using ij to run SQL scripts</h2>
<p>
<b>ij</b> scripts, files that end in an .sql extension and contain SQL
commands, can be run using the Derby plug-ins.
This allows you to use SQL scripts containing multiple commands
and run them in a single execution of <b>ij</b>.
</p>
<h3>Follow these steps to run an SQL script:</h3>
<ul>
<li>
Create a script which contains SQL commands and save the file with a .sql
extension. Remember to make the database connection your first command
in the script - no default connection exists.
<br/><br/>
</li>
<li>
Save the file in your current workspace, under your Java project, or import
it into your workspace.
<br/><br/>
</li>
<li>
Run the script using the menu item <b>Apache Derby, Run SQL script using 'ij'</b>
<br/><br/>
</li>
<li>
The output appears in the <b>ij</b> console window.
<br/><br/>
</li>
</ul>
<h3>Example of creating and running an SQL script</h3>
<p>
We'll go through a complete example below with an sql file called
<b>restaurants.sql</b>. This script relies on a table we created in the
help section, <a href="ij.html">Use ij to issue SQL commands.</a>
Run that SQL prior to completing these steps.
</p>
<p>
From the main Eclipse menu select <b>File, New, File</b>.
</p>
<blockquote>

</blockquote>
<p>
Use the current Java project as the parent folder, for example, myJavaProject.
Name the file <b>restaurants.sql</b>, and click <b>Finish</b>.
</p>
<p>
Now the workspace will look like this.
</p>
<blockquote>
<img src="images/create_restaurant.GIF" alt="Adding an sql file to the Java project" width="858" height="681"></img>
</blockquote>
<p>
Type the following in the restaurants.sql editor window (you may need to
double click the restaurants.sql file to create an editor window to type in.)
</p>
<pre>
connect 'jdbc:derby://localhost:1527/myDB;create=true;user=me;password=mine;';
insert into restaurants values (4, 'Grande Burrito', 'Oakland');
update restaurants set city = 'Ukiah' where name = 'Irifunes';
select * from restaurants;
disconnect;
exit;
</pre>
<p>
Now save the restaurants.sql file so we can run the script. Use <b>Ctrl + S</b>
in the windows environment to save an open file. Once the file has been saved
the asterisk will disappear next to the name of the file in the editor.
</p>
<p>
The last step is to run the SQL script. Right-click the <b>restaurants.sql</b>
file in the <b>Package Explorer</b> view and select <b>Apache Derby, Run SQL
Script using 'ij'</b>.
</p>
<blockquote>

</blockquote>
<p>
The <b>Console</b> view shows the SQL commands contained in the file
and executing in <b>ij</b> along with the output of the commands.
