Sinossi
This block introduces SQL, the Structured Query Language - the standard language for data management tasks. First, it introduces you to SQL's facilities for retrieving data from a database using increasingly complex queries. Then it looks at how to use SQL to define and populate tables, define constraints on the data and modify the data held in the database. Finally, it looks at some programming structures that can be used to embed SQL in application processes.
