I have two tables - element and example. I want to find element like items 
in example table but their status should either be 0 or 2.

I have written a query to fetch records from two tables as given below:

    
rows=db(('instr(microelementexamplestest.example,microelementstest.element)') 
&         
(db.microelementexamplestest.verificationstatus.belongs((0,2)))).select(db.microelementstest.id,db.microelementexamplestest.id,db.microelementexamplestest.verificationstatus)

But I get this error : TypeError: unsupported operand type(s) for &: 'str' 
and 'Query'".

Please help me to fix this.
