<h3><pre>db del

<h1>Description</h1>
<p>The <i>db</i> <b>del</b> command removes key/data pairs from the database.
<p>In the presence of duplicate key values, all records associated with the
designated key will be discarded.
<p>The options are as follows:
<p><dl compact>
<p><dt>-auto_commit<dd>Enclose the call within a transaction. If the call succeeds, changes
made by the operation will be recoverable. If the call fails, the
operation will have made no changes.
<p><dt>-glob<dd>The specified key is a wildcard pattern, and all keys matching that
pattern are discarded from the database. The pattern is a simple
wildcard, any characters after the wildcard character are ignored.
This option only works on databases using the Btree access method.
<p><dt>-txn txnid<dd>If the operation is to be
transaction-protected (other than by specifying the -auto_commit flag),
the <b>txnid</b> parameter is a transaction handle returned from
<i>env</i> <b>txn</b>.
</dl>
<p>The <i>db</i> <b>del</b> command returns 0 on success, and in the case of error, a Tcl error
is thrown.
