connectiondetails.hbm

<hibernate-mapping>     <class name="com.mypackage.cconnectiondetails"         table="connectiondetails">         <id name="connectionuniqueidentity" type="java.lang.string">             <column name="connectionuniqueidentity" />             <generator class="assigned" /> 

edit :

query query = currentsession().createsqlquery(sql); 

i changed code

query query = currentsession().createsqlquery(sql); 

to

query query = currentsession().createquery(sql); 

and worked.
