It is mostly needed for implementation of application specific database types. Look at the example in <a class="el" href="classdbComponent.html">dbComponent</a> class. The effect of addeing dbExpression to the query is the same as if this expresion is enclosed in parenthesis. <p><hr>The documentation for this class was generated from the following file:<ul><li><a class="el" href="query_8h-source.html">query.h</a></ul><hr size="1"><address style="align: right;"><small>Generated on Thu Feb 12 13:04:49 2004 for FastDB by<a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border=0 > </a>1.3.5 </small></address></body></html>⌨️ 快捷键说明
