<p>An efficient way to declare an associative array is with a <a id="sthref514" name="sthref514"></a>cursor, using the following procedure. The procedure uses each necessary statement in its simplest form, but provides references to its complete syntax.</p>
<a id="TDDDG241" name="TDDDG241"></a>
<p class="subhead2">To use a cursor to declare an associative array:</p>
<ol>
<li>
<p>In the declarative part:</p>
<ol>
<li>
<p>Declare the cursor:</p>
<pre xml:space="preserve" class="oac_no_warn">
CURSOR <span class="italic">cursor_name</span> IS <span class="italic">query</span>;
</pre>
<p>For complete explicit cursor declaration syntax, see <a href="javascript:open('http://www.oracle.com/pls/db112/lookup?id=LNPLS01307','newWindow').focus()"><span class="italic">Oracle Database PL/SQL Language Reference</span></a>.</p>
</li>
<li>
<p>Declare the associative array type:</p>
<pre xml:space="preserve" class="oac_no_warn">
TYPE <span class="italic">array_type</span> IS TABLE OF <span class="italic">cursor_name</span>%ROWTYPE
  INDEX BY { PLS_INTEGER | VARCHAR2 <code><span class="codeinlineitalic">length</span></code> }

</li>
<li>
<p>Declare an associative array variable of that type:</p>
<pre xml:space="preserve" class="oac_no_warn">
<span class="italic">array_name  array_type</span>;
</pre>
<p>For complete variable declaration syntax, see <a href="javascript:open('http://www.oracle.com/pls/db112/lookup?id=LNPLS01388','newWindow').focus()"><span class="italic">Oracle Database PL/SQL Language Reference</span></a>.</p>

<p>The following example uses the preceding procedure to create two associative arrays, <code>employees_jobs</code> and <code>jobs_</code>, and then declares a third associative array, <code>job_titles_type</code>, without using a cursor. The first two arrays are indexed by integer; the third is indexed by string.</p>
<div class="helpinfonote">
<p><span class="bold">Note: </span>The <code>ORDER</code> <code>BY</code> clause in the declaration of <code>employees_jobs_cursor</code> determines the storage order of the elements of the associative array <code>employee_jobs</code>.</p>
