L6: Advanced Structured Queries (english)
•
0 likes•98 views
This document covers advanced structured query concepts in i-views, including utility queries, local macros, registered macros, and scripting possibilities. Utility queries allow connecting queries with logical operations like negation and filtering. Local macros can replace long condition branches that are reused in a query to make it more readable. Registered macros make reusable condition paths available across multiple queries. Scripting enables enhanced value comparisons and accessing structured queries from JavaScript. The homework assigns practicing these concepts by building queries using local macros, registered macros with identifiers, and attribute conditions with scripted comparisons.

- 27. 2727 Advanced Structured Queries Homework Compose a structured query to practise the learned concepts: 1. Build a query that makes use of the local macro concept and use this macro twice in the query (hint: alternative). 2. Build a query that makes use of the global macro concept and extend the used macro with a further condition (hint: use identifiers in the macro query). 3. Build a query that contains an attribute condition, making use of a script calculated compare value.
