Structured Query Language (SQL) is the programming language for managing data in relational databases. In this course, you will practice writing your own SQL queries to retrieve, summarize and even modify data, and answer questions concerning your agency’s business information. You will also discuss the theory and logic behind the language and its elements. We will use SQL Server and T-SQL (Microsoft’s SQL dialect) for class exercises, but the material is useful for anyone using other relational database systems, such as Oracle, MySQL or Access.
Performance Objectives: Upon completion of this course you should be able to:
- Retrieve data using SELECT statement and WHERE, GROUP BY, HAVING, ORDER BY, and TOP clauses.
- Handle null values.
- Join multiple tables using cross, inner, and outer joins.
- Work with self-contained, correlated and aggregate sub queries.
- Use set operations such as UNION, INTERSECT, and EXCEPT.
- Modify data with the INSERT, DELETE and UPDATE statements.
