Introduction to Transact-SQL - Revised
Gain a better understanding of what SQL and Transact-SQL are and learn how to query databases using T-SQL.
Description
This course begins by teaching you how to set up an Azure SQL Database environment. SQL stands for Structured Query Language and is generally used as a standard across the industry for interrogating databases. You will learn how to construct SELECT statements to return data from a database and describe the different data types and their uses. You will also learn how to identify NULL functions and how they work with SQL queries.
You will then learn how to remove duplicates from SQL query searches, sort SQL query results, and construct a SQL query with predicates and filtering. This course will also teach you the concept and uses of a Join. You will learn where to implement Joins in SQL queries, how to apply the UNION operator in a SQL query to combine data from two different tables, and where to add INTERSECT and EXCEPT operators in a SQL queries.
Mastering the process of querying database is a very useful skill that you can easily acquire with this databases course from Alison. Once you have gone through all the modules, you will gain a better understanding of how to combine queries using the Intersect and Except queries, how logical function works, how to filter using the group by sub clause and Having clause, and more!
