<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>-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.
|
|
<p><dt>-txn txnid<dd>If the file is being accessed under transaction protection, 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.
