Mastering SQL Query With SQL Server

Define data as information stored in your computer to be processed later, including personal details, social activity, and transactions, then see how organizations use databases to manage it.

Understand why we need SQL to talk to a database and how SQL's standards-based syntax works across Microsoft, Oracle, MySQL, PostgreSQL.

Explore relational databases with tables, rows, and columns, plus NoSQL options like document, key-value, column-based, and graph databases; the course centers on SQL Server, with hands-on SQL scripting.

Install and configure SQL Server and SQL Server Management Studio (SSMS) to create databases, connect with authentication, and run queries using the developer edition and database engine service.

Insert data into tables using insert into table syntax, add single or multiple rows by listing columns and values, then verify with a select statement; this is a DML operation.

Learn to update data in SQL Server using the update statement, set clauses, and where conditions to affect single, multiple, or all records, including multi-column updates.

Delete data by using delete from a table with a where clause to remove rows, or drop the table to erase all data; without a where clause, all records delete.

Learn how to alter tables in SQL Server by adding, dropping, and modifying columns, with practical examples like phone number, session, and class room number, and data type changes.

learn to set up a sql server database, create and rename tables, and insert, update, and delete records. apply column alterations, drop columns, and rename columns for a clearer schema.

Learn why data query language is important for data analysts, and how to extract data using select statements, read specific columns, order results, rename columns, and restrict records.

Learn how to select specific columns from a table in SQL Server, including extracting multiple columns, renaming with aliases, and handling multi-word headers with quotes or brackets.

Apply basic filters in SQL Server by using the where condition to select specific columns and rows, with equal and not equal comparisons, and proper handling of quotes for strings.

Learn to use comparison operators in SQL Server to filter data by value ranges, including greater than, less than, and their equal to variants, with salary and date examples.

Master the in and not in operators to match multiple values exactly, filter by city or date, and exclude records, with practical sql server examples.

Master the between operator to filter data by a range, including minimum and maximum values, with examples like salary between 50,000 and 60,000 and date ranges.

Apply not null constraints to prevent null values in sql server, ensuring valid names and emails, and understand how unique constraints interact with nulls.

Apply a check constraint to a product table to enforce price greater than zero, and use primary key, not null, and unique constraints to ensure product ids and product names.

Explore how foreign keys enforce referential integrity between related tables, such as customers and orders, by validating customer ids when new orders are stored.

Explore aggregate functions to analyze millions of records by grouping rows, computing totals by country and year, while learning about identity keys, constraints, and foreign keys.

Master aggregate functions, including sum, min, max, avg, and count, and group by country and invoice year to analyze sales, using where and having filters and optional aliases.

Explore how inner, left, right, and full outer joins combine data, explain base table concepts, and handle nulls to map matching and nonmatching records.

Master the inner join by using table aliases to pull matching records from book and author tables, ensuring data exists in both datasets for output.
