GeneralInformation

• Construction

• Use cases• You need to access acondition branch inseveral places

• Unclutter your search

Local Macro - Continued

• Use local macros to replace long paths that you need inseveral places inyour structured query

• Use identifiers to access certain points inthe macro,typically the endpoints of the path

• Endpointscan then be extended as needed

Homework

Compose astructured query to practise the learned concepts:

1. Build aquery that makes use of the local macro concept and use this macro twice inthe query (hint:alternative).

2. Build aquery that makes use of the globalmacro concept and extend the used macro with afurthercondition (hint:use identifiers inthe macro query).

3. Build aquery that contains anattribute condition,making use of ascript calculated compare value.
