| <p>
| |
| <var>Cursor</var> is a member of the <var>[[Recordset class|Recordset]]</var> class.
| |
| </p>
| |
| | |
| Instantiates a <var>[[RecordsetCursor class|RecordSetCursor]]</var> object for a
| |
| particular instance of a <var>Recordset</var> object.
| |
| ==Syntax==

| |
| </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 ''%rs'' has at least one record. If ''%rs'' has no records, <var>Cursor</var> returns a <var>Null</var> object.
| |
| </td></tr>
| |
| <tr><th>%rs</th>
| |
| <td>A reference to an instance of a <var>Recordset</var> object.
| |
| </td></tr>
| |
| <tr><th><b>LoopLockStrength=</b>lockstrength</th>
| |
| <td>The lock strength to be used for <var>For Record At</var> loops on the cursor. This is an optional, [[Notation conventions for methods#Named parameters|name required]], parameter, available in <var class="product">Sirius Mods</var> 7.0 and later. It defaults to <var>None</var>. See [[RecordsetCursor#LoopLockStrength for RecordsetCursors|"LoopLockStrength for RecordsetCursors"]].

| ==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 (Recordset 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>
