Hi Rainer,

I am new to empire-db.  The SQL below is what I would like empire-db to 
generate.

select count(*)
from circuit_equipment
where circuit_with_attr_id in (select circuit_with_attr_id from 
customer_circuit_impact
                                                             where item_id = 
74006036);

I am seeing this from empire-db when I print out my DBCommand.  I would like to 
know why is empire-db adding the table CUSTOMER_CIRCUIT_IMPACT in the FROM 
statement.  The query below take a long time to run because of the extra table 
that was added.

SELECT count(*)
FROM CIRCUIT_EQUIPMENT t6, CUSTOMER_CIRCUIT_IMPACT t7
WHERE t6.CIRCUIT_WITH_ATTR_ID IN ((SELECT t7.CIRCUIT_WITH_ATTR_ID
FROM CUSTOMER_CIRCUIT_IMPACT t7
WHERE t7.ITEM_ID=74006036))

Here is the code that produced the SQL above.
            DBCommand impactCmd = db.createCommand();
            impactCmd.select( 
db.T_CUSTOMER_CIRCUIT_IMPACT.C_CIRCUIT_WITH_ATTR_ID );
            addWhereClauseForType(impactCmd, idType, lID);
            DBQuery CIRCUIT_WITH_ATTR_ID = new DBQuery(impactCmd);

            DBCommand dbCmd = db.createCommand();
            dbCmd.select( db.T_CIRCUIT_EQUIPMENT.count() );
            dbCmd.where( 
db.T_CIRCUIT_EQUIPMENT.C_CIRCUIT_WITH_ATTR_ID.in(CIRCUIT_WITH_ATTR_ID) );

Please help.

Thank You,
