<h1>Tutorial: Changing a Package Specification</h1>
<a name="BEGIN" id="BEGIN"></a>
<p>To change a <a id="sthref384" name="sthref384"></a>package specification, use either the SQL&nbsp;Developer tool Edit or the DDL statement <a id="sthref385" name="sthref385"></a><code>CREATE</code> <code>PACKAGE</code> with the <code>OR</code> <code>REPLACE</code> clause.</p>
<p>This tutorial shows how to use the Edit tool to change the specification for the <a id="sthref386" name="sthref386"></a><code>EMP_EVAL</code> package (created in <a href="tdddg_subprograms014.htm#CIHHDBFE">"Tutorial: Creating a Package Specification"</a>). Specifically, the tutorial shows how to add declarations for a procedure, <code>eval_department</code>, and a function, <code>calculate_score</code>.</p>
<a id="TDDDG221" name="TDDDG221"></a>
<p class="subhead2">To change EMP_EVAL package specification using the Edit tool:</p>
<ol>
<li>
<p>On the Connections tab, expand <span class="bold">hr_conn</span>.</p>
<p>Under the <code>hr_conn</code> icon, a list of schema object types appears.</p>
</li>
<li>
<p>Expand <span class="bold">Packages</span>.</p>
<p>A list of packages appears.</p>
</li>
<li>
<p>Right-click <span class="bold">EMP_EVAL</span>.</p>
<p>A list of choices appears.</p>
</li>
<li>
<p>Click <span class="bold">Edit</span>.</p>
<p>The <code>EMP_EVAL</code> pane opens, showing the <code>CREATE</code> <code>PACKAGE</code> statement that created the package.</p>
<p>The title of the pane is not in italic font, which indicates that the package is saved in the database.</p>
</li>
<li>
<p>In the <code>EMP_EVAL</code> pane, replace the comment with this code:</p>
<pre xml:space="preserve" class="oac_no_warn">
PROCEDURE eval_department ( dept_id IN NUMBER );

FUNCTION calculate_score ( evaluation_id IN NUMBER
                         , performance_id IN NUMBER)
                         RETURN NUMBER;
</pre>
<p>A new <code>EMP_EVAL</code> pane opens, showing the changed <code>CREATE</code> <code>PACKAGE</code> statement. The title of the pane is in italic font, which indicates that the changes have not been saved to the database.</p>
</li>
<li>
<p>Click the icon <span class="bold">Compile</span>.</p>
<p>The changed package specification compiles and is saved to the database. The title of the <code>EMP_EVAL</code> pane is no longer in italic font.</p>
</li>
</ol>
