Solve the following python programming problem given the following code:
def _condition_as_sql(self, qn, connection) : 
    '
        Return sql for condition.
        ' 
    def escape(value) : 
        if isinstance (value, bool) : 
            value = str (int (value)) 
if isinstance (value, six.string_types) : 
            if ('%' in value) : 
                value = value.replace ('%', '%%') 
if ("'" in value) : 
                value = value.replace ("'", "''") 
value = (("'" + value) + "'") 
return value 
(sql, param) = self.condition.query.where.as_sql (connection, connection) 
    param = map (escape, param) 
    return (sql % tuple (param)) 

    
    

    Fix the buggy line: (sql, param) = self.condition.query.where.as_sql (connection, connection)

#Here is Python program to fix the buggy line: (sql, param) = self.

(sql, param) = self.condition.query.where.as_sql (qn, connection)
