OVERVIEW

CURRICULUM

Lesson 1. Harnessing SQL for Dynamic Web Applications

Tables in relational databases store information in rows and columns, with primary keys ensuring each record is unique. Proper table design and data type selection prevent errors and enhance data retrieval performance in SQL applications.

Lesson 2. SQL SELECT Essentials

Upon delving into SQL's SELECT statement, Lesson 2 underscores best practices for retrieving specific data by demonstrating column selection, handling WHERE clause conditions, and understanding the impact of using asterisks. It also covers using DISTINCT for deduplication and applying ordering techniques while addressing the role of NULL values.

Lesson 3. Quick Guide: SQL Data Updates

The 'UPDATE' command in SQL empowers users to adjust table data effectively, with the ability to update multiple fields and integrate queries for precision. However, neglecting the WHERE clause can lead to sweeping updates, thus knowing the syntax and logic is critical for protecting data integrity.

Lesson 4. Mastering SQL: Adding Data with INSERT Statements

Mastering the SQL INSERT statement involves understanding its syntax and limitations, such as data type adherence and primary key uniqueness. Leveraging auto-increment functions eliminates manual ID tracking, while importing data from other tables is streamlined when paired with SELECT statements.

Lesson 5. Mastering SQL's DELETE Statement: Precision in Data Management

Understanding how to delete data in SQL requires caution due to the risk of creating orphaned records or accidentally deleting all data. Techniques include using carefully constructed WHERE clauses and utilizing verification steps like SELECT statements to ensure accuracy.

Lesson 6. Organize Your Data: A Guide to SQL Sorting and Filtering

Implementing sorting with the ORDER BY feature in SQL can align your data in either ascending or descending order, leveraging multiple column criteria for complex data arrangements. Filtering via the WHERE clause refines data selection through specified conditions, ensuring that database queries yield pertinent and actionable information.

Lesson 7. Advanced SQL: Constructing Precise Data Queries

The SQL LIKE operator grants flexible pattern matching using wildcards, allowing searches for strings within arbitrary positions, and combined with NOT, it refines queries to exclude specific sequences from results.

Lesson 8. Harnessing the Power of SQL Functions for Data Insights

Leveraging SQL, data summaries can be crafted quickly using built-in aggregate functions, ensuring precision and scalability in reporting tasks. The tutorial emphasizes the use of WHERE clauses for data filtering and the importance of aliases for improved readability.

Lesson 9. Harnessing the Power of GROUP BY in Data Analysis

Utilizing SQL's GROUP BY clause enables structured aggregation of data, such as compiling customer counts by city, essential for data analysis and reporting. Proper syntax and clause ordering, including WHERE for filtering and HAVING for additional group conditions, are key to successful operation.

Lesson 10. Exploring the Depths of SQL: Mastering Subqueries

Subqueries allow users to perform advanced data retrieval by embedding SELECT statements within other SQL queries, enabling the seamless integration of data from various databases. This capability is particularly useful in scenarios such as updating customer order dates through cross-referencing linked databases.

Lesson 11. Unleashing the Power of JOIN: Enhancing SQL Query Performance

Lesson 11 teaches us the power of JOIN in SQL, enhancing query performance by linking tables instead of relying on subqueries. By using JOINs, you can easily and efficiently consolidate data from multiple tables, making your reports faster and easier to generate.

Lesson 12. Designing Stable and Scalable Tables

Designing and managing tables is crucial for database performance, integrity, and scalability, involving tasks such as creating, editing, and deleting tables. Proper table naming and normalization prevent data redundancy and ensure efficient data retrieval.

Lesson 13. Views: Enhancing SQL Efficiency

Views act as virtual tables created from preset data sets, helping to speed up query execution by storing common SQL Select statements. Despite their benefits, views have limitations such as the inability to take dynamic query parameters.

Lesson 14. Enhancing Your Database with Stored Procedures

Stored procedures in SQL encapsulate complex operations into reusable scripts that perform tasks like querying or modifying data, supporting input arguments to adapt to varying needs. They allow for safer and efficient data handling through options to modify or remove them when needed.

Lesson 15. Navigating SQL: Mastering the Cursor Challenge

Despite their ability to handle granular data operations, cursors in SQL are resource-intensive and often replaceable by conditional statements. Developers should focus on query optimization, leveraging indexes, and limiting record processing to avoid performance issues.

Lesson 16. Mastering Transactions for Robust Data Management

When working with Customer and Order tables, removing a customer without deleting related orders causes orphaned records, disrupting data integrity. Transactions provide a way to execute multiple SQL operations as a unit, allowing rollback if any part fails.

I provide support for a software program that uses SQL Server as the backend database and this class answered so many questions I have had ! Many of our customers use select statements and stored procedures and I have never been able to understand how they are put together and how the syntax should be structured. The course started with an overview and then moved on one step at a time building on what I already knew at a pace I could keep up with.
