Take care of the queries
Goals
There are always several ways to write a query, and several ways to get the same result. But not all ways are necessarily equivalent. Analyzing and measuring are the two key words to understand what’s going on under the hood and to code in the most efficient way. This session will illustrate these different options with concrete examples and will propose a study of the exchanges generated with the server.
Benefits
At the end of this session you will be able to:
- Understand the importance of choices when faced with different coding options.
- Determine which option is the most adapted to a given context.
What you will learn
- The multiple possible syntaxes to perform queries in the database using the ORDA language exclusively
- How to analyze queries with the tools provided in 4D.
Who should attend this session?
- 4D developers who are interested in understanding how to correctly write queries using ORDA.
- 4D developers who are comfortable with ORDA.
