+
+Returns the last value created in an ``auto-increment'' field.
+
+
+\subsubsection{Transaction Control Database Functions}
+
+By default the database functions shall behave as if each operation effects a
+permanent change to the database.  An API is provided to change this behavior
+such that operations may be grouped together into a ``transaction'' that is
+atomic.
+
+\begin{prototype}
+bool psDBExplicitTrans(
+    psDB *dbh,                          ///< Database handle
+    bool mode                           ///< transactions enable/disable
+);
+\end{prototype}
+
+Enable/Disable explicit transactions.  When enabled \code{psDBCommit()} must
+be called to make changes to the database's state persistent.
+
+\begin{prototype}
+bool psDBTransaction(
+    psDB *dbh                           ///< Database handle
+);
+\end{prototype}
+
+Start a new transaction.
+
+\begin{prototype}
+bool psDBCommit(
+    psDB *dbh                           ///< Database handle
+);
+\end{prototype}
+
+Commit the current transaction.
+
+\begin{prototype}
+bool psDBRollback(
+    psDB *dbh                           ///< Database handle
+);
+\end{prototype}
+
+Undo the current transaction.
+
+
+\subsubsection{Low Level Database Functions}
+
+This collection of functions is primarily intended for us internally by the
+other database functions.  However, in certain cases their direct use may be
+needed to express semantics that are not supported by the public database
+interface.
+
+\begin{prototype}
+long p_psDBRunQueryPrepared(
+    psDB *dbh,                          ///< Database handle
+    const psArray *rowSet,              ///< row data as psArray of psMetadata
+    const char *format,                 ///< SQL string to execute
+    ...
+);
+\end{prototype}
+
+\code{p_psDBRunQueryPrepared()} is similar to \code{p_psDBRunQuery()} except
+that \code{format} is expected to be a query string with value ``place
+holders'' in it.  This allows the data in \code{rowSet} is inserted into the
+database via the use of a more efficent ``prepared query''.
+
+\begin{prototype}
+psArray *p_psDBFetchResult(
+    psDB *dbh                          ///< Database handle
+);
+\end{prototype}
+
+\code{p_psDBFetchResult()} is the inverse operation of \code{p_psDBRunQuery}.
+It shall load the latest result set from the database into an \code{psArray}
+and return it.
