<b>Description(db del)</b>
|
|
<p>The <i>db</i> <b>del</b> command removes key/data pairs from the database.</p>
|
|
<p>In the presence of duplicate key values, all records associated with the
|
|
designated key will be discarded.</p>
|
|
<p>The options are as follows:</p>
|
|
<br>
|
|
<b>-glob</b><ul compact><li>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.</ul>
|
|
<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>The <i>db</i> <b>del</b> command returns 0 on success, and in the case of error, a Tcl error
|
|
is thrown.</p>
