25<b>Description(db cursor)</b>
26<p>The <i>db</i> <b>cursor</b> command creates a database cursor.  The returned
27cursor handle is bound to a Tcl command of the form <b>dbN.cX</b>,
28where X is an integer starting at 0 (for example, db0.c0 and db0.c1).
29It is through this Tcl command that the script accesses the cursor
30methods.</p>
31<p>The options are as follows:</p>
32<br>
33<b>-txn txnid</b><ul compact><li>If the operation is part of an application-specified transaction, the
34<b>txnid</b> parameter is a transaction handle returned from
35<i>env</i> <b>txn</b>.  If no transaction handle is specified, but the
36operation occurs in a transactional
37database,
38the operation will be implicitly transaction protected.</ul>
39<br>
40<p>In the case of error, a Tcl error is thrown.</p>
