Hi,

I would like to ask you how to query map mapping using HQL. I have mapping eg.:

<class name="A">
<map name="strings">
<key>
<column name="MASTER"/>
</key>
<composite-index class="B">
<key-property name="s1" column="KEY1"/>
<key-property name="s2" column="KEY2"/>
</composite-index>
<element type="B">
<column name="VALUE1"/>
<column name="VALUE2"/>
</element>
</map>
</class>

And now I want to select A which has KEY1 column is 'X' and VALUE1 column is 'Y'?

Thanks
