|
<b>Description: DB_SEQUENCE->remove</b>
|
|
<p>The DB_SEQUENCE->remove method removes the sequence from the database. This
|
|
method should not be called if there are other open handles on this
|
|
sequence.</p>
|
|
<p>The <a href="../api_c/seq_class.html">DB_SEQUENCE</a> handle may not be accessed again after DB_SEQUENCE->remove is
|
|
called, regardless of its return.</p>
|
|
<p>The DB_SEQUENCE->remove method
|
|
returns a non-zero error value on failure
|
|
and 0 on success.
|
|
</p>
|
|
<b>Parameters</b> <br>
|
|
<b>flags</b><ul compact><li>The <b>flags</b> parameter must be set to 0 or by bitwise inclusively <b>OR</b>'ing together one
|
|
or more of the following values:
|
|
<br>
|
|
<b><a name="DB_TXN_NOSYNC">DB_TXN_NOSYNC</a></b><ul compact><li>If the operation is implicitly transaction protected (the <b>txnid</b>
|
|
argument is NULL but the operation occurs to a transactional database),
|
|
do not synchronously flush the log when the transaction commits.</ul>
|
|
<br></ul>
|
|
<b>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
|
|
<a href="../api_c/txn_begin.html">DB_ENV->txn_begin</a>; if the operation is part of a Berkeley DB Concurrent Data Store group, the
|
|
<b>txnid</b> parameter is a handle returned from
|
|
<a href="../api_c/env_cdsgroup_begin.html">DB_ENV->cdsgroup_begin</a>; otherwise NULL.
|
|
If no transaction handle is
|
|
specified, but the
|
|
operation occurs in a transactional
|
|
database,
|
|
the operation will be implicitly transaction protected.
|
|
</ul>
|
|
<br>
|
|
<br><b>Errors</b>
|
|
<p>The DB_SEQUENCE->remove method
|
|
may fail and return one of the following non-zero errors:</p>
|
|
<br>
|
|
<b>EINVAL</b><ul compact><li>An
|
|
invalid flag value or parameter was specified.</ul>
