Learn how to design numeric columns in a product table by comparing float, real, and decimal, balancing weight precision and price accuracy for reliable SQL Server data.
Learn how primary key column constraint uniquely identifies a row, enforces not null, uses identity to increment, and creates a clustered index to boost performance with product_id in SQL Server.
Master the delete from table where clause to safely target rows in SQL Server, avoid accidental full table deletions, and see results in SQL Management Studio.
Master the cast function to convert data types in SQL Server, casting integers to varchar for safe concatenation with strings and preventing conversion errors.
Construct an insert statement from the sales table by concatenating first name and last name, escaping single quotes, and casting performance to word char ten, while excluding the sales id.
Explore assignment seven by counting customer orders, counting products per order with left joins, computing price times quantity for averages, listing frequent customers, ranking products by popularity, and applying having.
Learn how variables serve as input parameters and store intermediate results in a multi-statement SQL script, with examples using average performance to filter salespeople.
Identify the most popular category by joining order lines to products, summing quantities, and ordering by total, then fetch matching products for that category.
Add a status column to the orders table and use if else logic on order date to set shipped for older dates and pending for newer ones.
Learn to tackle a complicated sql assignment by joining category and order lines, aggregating total quantity by category, and using a case expression to label low, mid, and high demand.
Compare temp tables and table variables in SQL Server, highlighting when to use each for performance, memory, and disk considerations.

SQL (Structured Query Language) is a universal language for working with data. It allows you to communicate with databases and perform various operations on data, such as creating tables, inserting records, updating values, deleting rows, and much more.
SQL is also essential for data analysis, as it enables you to extract, filter, aggregate, and transform data from multiple sources and formats. SQL skills are in high demand in many industries and roles, such as business intelligence, data science, web development, and software engineering.
Why learn SQL with SQL Server?
In this course, you will learn SQL with SQL Server, one of the most popular and powerful database platforms in the world. SQL Server is used by many leading companies and organizations, and it offers many features and tools for data storage, analysis, and management. SQL Server is also the number one database platform in terms of job opportunities. According to LinkedIn Jobs, at the time of writing this course description, SQL Server has more than 90K open jobs in the United States, which is more than double the second position, which is MySQL.
What will this course teach you?
In this course, you will learn SQL from scratch, starting with the basics and progressing to more advanced topics. You will learn how to:
Install SQL Server and SMSS (SQL Server Management Studio), the tools you need to work with SQL
Execute SQL statements with SMSS, using different methods and views
Use Data Definition Language (DDL) to create and delete databases and tables
Define data types and column constraints for your tables
Use Data Manipulation Language (DML) to insert, update, and delete data from your tables
Query data using various clauses, operators, functions, and joins
Apply sorting, grouping, aggregation, and filtering techniques to your queries
Combine data from multiple tables using unions and views
Write SQL programs using variables, conditional logic, loops, and subqueries
Use temporary tables and table variables to store intermediate results
Create and use stored procedures and functions to modularize and reuse your code
Write dynamic SQL to generate and execute SQL statements dynamically
Update data using joins and subqueries
But this is not just a theoretical course. This is a practical course, where you will get to apply your SQL skills to real-life scenarios. I have designed this course based on my own experience working with SQL in various projects over the past two decades. You will get to solve real-world problems using SQL.
What are the benefits of taking this course?
By the end of this course, you will have a solid foundation in SQL and be able to write efficient and effective queries for any data-related task. You will also have access many assignments to practice your knowledge and skills.
Who is this course for?
This course is designed for beginners who have little or no prior experience with SQL. No programming background is required, although some basic familiarity with computers and databases is helpful. All you need is a computer with an internet connection and a willingness to learn.
