Usage Notes

New page

<span class="pageSubtitle"><section begin=dpl_desc/><section end=dpl_desc/></span>
[[Category:SortedRecordset methods|Cursor constructor]]
<p>
<var>Cursor</var> is a member of the <var>[[SortedRecordset class|SortedRecordset]]</var> class.
</p>

Instantiates a <var>RecordsetCursor</var> object for a
particular instance of a <var>SortedRecordset</var> object.
==Syntax==
<p class="syntax">%rscursor = %srecs:Cursor
</p>
===Syntax terms===
<table class="syntaxTable">
<tr><th>%rscursor</th>
<td>A declared <var>RecordsetCursor</var> object, to which <var>Cursor</var> returns an instance of a <var>RecordsetCursor</var> object, if ''%srecs'' has at least one record. If ''%srecs'' has no records, <var>Cursor</var> returns a <var>Null</var> object.
</td></tr>
<tr><th>%srecs</th>
<td>A reference to an instance of a <var>SortedRecordset</var> object.

</td></tr></table>
==Usage Notes==
<ul>
<li>You can have as many cursors as you want for a record set.
<li>To test for an empty record set, use
<var>[[IsEmpty (SortedRecordset property)|IsEmpty]]</var>, which
is much more efficient than testing the record <var>Count</var> for 0.
<li>The instantiated <var>RecordsetCursor</var> is automatically
positioned on the first record in the set.
</ul>
