With over 7 years of hands-on experience as an SQL expert and seasoned trainer, this course will guide you through various modules to enhance your data analysis capabilities using the Transact-SQL (T-SQL) language.
Course Goals:
- Master the fundamentals: Gain a deep understanding of SQL, its process, commands, and the concepts of relational database management systems (RDBMS). Learn various syntaxes, data types, and SQL operators. Develop the skills to retrieve data using SELECT queries, perform concatenation, work with data types, and handle NULL values.
- Sorting and Filtering Query Results: Learn how to sort query results using the ORDER BY clause, restrict results using TOP, and retrieve specific pages of results using OFFSET and FETCH. Understand the options for ALL and DISTINCT filtering and utilize the WHERE clause for result filtering. Explore the usage of AND and OR operators for conjunctive conditions.
- Query Multiple Tables with Joins: Understand the concept of joining tables and learn various types of joins, including inner joins, outer joins, cross joins, self joins, left joins, and right joins. Gain proficiency in querying data from multiple tables by using appropriate join techniques.
- Subqueries: Explore the power of subqueries in SQL. Learn to use simple subqueries, correlated subqueries, and subqueries with SELECT, INSERT, UPDATE, and DELETE statements. Understand how to effectively incorporate subqueries in your data analysis workflows.
- Scalar Functions: Gain expertise in using logical and aggregate functions in SQL. Learn how to perform calculations, group aggregated results using the GROUP BY clause, and filter groups using the HAVING clause. Utilize scalar functions to manipulate and analyze data effectively.
- Build and Modify Data in T-SQL: Acquire skills to create databases and tables, insert, update, delete, and truncate data. Learn essential data manipulation techniques to build and modify data using T-SQL.
By completing this course, you will:
- Develop a strong foundation in SQL and its data analysis capabilities.
- Gain proficiency in retrieving, sorting, filtering, and joining data.
