Do you need to analyse and work with large volumes of data?  For anyone looking to improve their knowledge of structured query language (SQL), this course will teach you how to write SQL SELECT statements to summarise and analyse your data.

This is one of four 4-hour modules that cover SQL.  These modules are independent and are provided at different times.  You can attend all modules or only those that are of interest to you.  Furthermore, you can attend the modules in any order (subject to the relevant prerequisites).

  • Group records with GROUP BY
  • Filter groups with HAVING
  • Change the database’s behaviour around case-sensitive text comparisons
  • Derive new classifications of records with CASE
  • Perform cross-tab queries, similar to pivot tables in a spreadsheet
