Take care of the queries

Take care of the queries

• Duration: 60 minutes
• Level: Advanced
• Language: English

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.
