If you inspected an *alias* instance after using one you would find that it's fields have been assigned numeric values.
These values have no meaning. They are assigned from a static counter in `com.iciql.Utils.newObject()` during execution of the *db.from()* method. + +If your statement is a query, like in the above example, iciql will generate new instances of your *alias* model class and return them as a list where each entry of the list represents a row from the JDBC `ResultSet`. + +### Why are Aliases not thread-safe? + +The _db.from(p)_ call reinstantiates each member field of p. Those reinstantiated fields are then subsequently used in clauses like _where(p.unitsInStock)_. If your *alias* instance is shared concurrently then its highly probable that when _queryA_ executes, _queryC_ has reinstantiated all the *alias* fields and broken _queryA's_ runtime field mapping. + +Depending on your design, you might consider using a [ThreadLocal](http://download.oracle.com/javase/6/docs/api/java/lang/ThreadLocal.html) variable if you do not want to keep instantiating *alias* instances. A utility function is included for easily creating ThreadLocal variables. + +%BEGINCODE% +final ThreadLocal<Product> p = Utils.newThreadLocal(Product.class); +db.from(p.get()).select(); +%ENDCODE% + +## Best Practices + +1. Close your *Db* instances when you are done with them, this closes the underlying connection or directs the pool to "close" the connection. +2. Aliases instances are not thread-safe so DO NOT SHARE an alias!
