<a name="id-1.2.9.3"></a>New unique parser</h2></div></div></div>
<p>Previous <span class="application">Libgda</span> versions had several builtin parsers relying on Lex/Yacc (or Flex/Bison) to analyze SQL with
the following limitations:
</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>not all the SELECT, INSERT, DELETE and UPDATE constructions were recognized</p></li>
<li class="listitem"><p>the parsers were generic and could not be adapted to the different database's SQL dialects</p></li>
<li class="listitem"><p>there were some difficult to track problems when several parsers are used at the same time</p></li>
</ul></div>
<p>
</p>
<p>All the parsers have been removed in favor of a new parser <a class="link" href="GdaSqlParser.html" title="GdaSqlParser">GdaSqlParser</a> object which
can be generic or specific to a database provider if the provider has specified it.</p>
<p>To create a generic <a class="link" href="GdaSqlParser.html" title="GdaSqlParser">GdaSqlParser</a> object, one can use the
<a class="link" href="GdaSqlParser.html#gda-sql-parser-new" title="gda_sql_parser_new ()">gda_sql_parser_new()</a> method, and for a parser adapted to a specific
database's SQL dialect, use the <a class="link" href="GdaConnection.html#gda-connection-create-parser" title="gda_connection_create_parser ()">gda_connection_create_parser()</a> method.</p>
<p>The new parser uses <a class="ulink" href="http://www.hwaci.com/sw/lemon" target="_top">LEMON</a> generated parsers.</p>
