PostgreSQL, like other DBMS systems, has added extra features of its own to standard SQL and these are also covered in the course.

Subsequently, the various components of SQL are discussed step-by-step, such as Data Definition Language with CREATE TABLE and Data Manipulation Language with INSERT and UPDATE. SQL Select Queries Next attention is paid to writing SELECT queries. This includes clauses such as WHERE, ORDER BY, LIKE and BETWEEN .. AND. The grouping of data by means of GROUP and HAVING clauses is also on the course schedule. SQL Functions The various standard SQL functions are also discussed.
