<b>Description(db get_join)</b>
|
|
<p>The <i>db</i> <b>get_join</b> command performs the cursor operations required to
|
|
join the specified keys and returns a list of joined {key data} pairs.
|
|
See <a href="../ref/am/join.html">Equality join</a> for more information on
|
|
the underlying requirements for joining.</p>
|
|
<p>The options are as follows:</p>
|
|
<br>
|
|
<b>-txn txnid</b><ul compact><li>If the operation is part of an application-specified transaction, the
|
|
<b>txnid</b> parameter is a transaction handle returned from
|
|
<i>env</i> <b>txn</b>. If no transaction handle is specified, but the
|
|
operation occurs in a transactional
|
|
database,
|
|
the operation will be implicitly transaction protected.</ul>
|
|
<br>
|
|
<p>In the case of error, a Tcl error is thrown.</p>
