<p style='margin-top:0;margin-bottom:10px;'>This pages describes the usage of the trim() function: <a href="http://thecafetechno.com/tutorials/hibernate/hql-concat-trim-function-example/" class="external-link" rel="nofollow">http://thecafetechno.com/tutorials/hibernate/hql-concat-trim-function-example/</a></p>
<p style='margin-top:0;margin-bottom:10px;'>We're using it like this:</p>
<div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent">
<pre>SELECT field.value FROM BaseObject as obj, StringProperty as field WHERE obj.name=:groupdocname and obj.className=:groupclassname and obj.id=field.id.id and (trim(both from field.value)<>'' or (trim(both from field.value) is not null and '' is null))
</pre>
</div></div>
<p style='margin-top:0;margin-bottom:10px;'>Thus we use the trim with 3 arguments (since we don't want to specify the character to trim, we want to use the default whitespace char).</p>
<p style='margin-top:0;margin-bottom:10px;'>However in Dialect.java, the trim() function is registered with 4 arguments only:</p>
<div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent">
<pre>registerFunction( "trim", new SQLFunctionTemplate( StandardBasicTypes.STRING, "trim(?1 ?2 ?3 ?4)" ) );
</pre>
</div></div>
<p style='margin-top:0;margin-bottom:10px;'>Thus in TemplateRenderer:java it prints the warning:</p>
<div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent">
<pre> public String render(List args, SessionFactoryImplementor factory) {
int numberOfArguments = args.size();
if ( getAnticipatedNumberOfArguments() > 0 && numberOfArguments != getAnticipatedNumberOfArguments() ) {
log.warn( "Function template anticipated {} arguments, but {} arguments encountered",
getAnticipatedNumberOfArguments(), numberOfArguments );
}
StringBuffer buf = new StringBuffer();
for ( int i = 0; i < chunks.length; ++i ) {
if ( i < paramIndexes.length ) {
final int index = paramIndexes[i] - 1;
final Object arg = index < numberOfArguments ? args.get( index ) : null;
if ( arg != null ) {
buf.append( chunks[i] ).append( arg );
}
}
else {
buf.append( chunks[i] );
}
}
return buf.toString();
}
</pre>
</div></div>
<p style='margin-top:0;margin-bottom:10px;'>It should be allowed to use the trim() function with only 3 arguments without any warning.</p>
