In this course, you will learn to write queries using ANSI standard Structured Query Language (SQL) with IBM Informix extensions. You will start with simple queries to select rows from a single table, then advance to more complex queries that involve subqueries or multitable joins. You will learn how to use functions and expressions in SQL statements and how to format the query results. In addition, you will learn how to perform insert, update, and delete operations, and how to select rows that contain large object and other non-standard data types.
