SQL- The Complete Introduction to SQL programming

A database is a collection of similar information stored together for a specific purpose, with examples like banking data, stock prices, or a to do list on paper or computer.

Compare relational and non-relational databases, explain their data models of rows and columns versus flexible documents, and outline CRUD operations using the database management systems.

Explore relational databases and keys, including primary, unique, super, ultranet, composite, and foreign keys, and how they create relations between tables.

Explore practical examples of key types in databases, including primary, unique, super, alternate, candidate, composite, and foreign keys, illustrated with a restaurant dataset in Excel and prep for sql.

Learn why SQL, a structured query language, works with relational database management systems to create, read, update, and delete databases, tables, and data through practical queries and basic admin tasks.

Install the MySQL server, Workbench, and shell from the community edition, then configure a local connection and explore basic database creation, scripts, and data import/export.

Explore how SQL keywords like create, table, primary key, insert, select, and from drive database operations, table creation, and data insertion, with examples and syntax basics.

Explore the three core data type categories—strings, numbers, and date/time—and learn how fixed-length char contrasts with variable-length varchar, plus common subtypes like text, blob, and timestamp.

Create a database named menu, switch to it with the use statement, and delete databases with drop to demonstrate basic SQL database management.

Create a database named restaurant types, use it, and create a table all types with a num column to store the number of restaurants.

Learn to modify tables in sql by using alter and add, create and use databases, and drop tables to manage clothing line data with collection, price, and name columns.

Create a restaurant database and a lists table with name, address, and income columns. Define a not null, unique primary key column NUM to identify each entry as an integer.

Combine two tables in a restaurant database by turning the primary key into a foreign key in the menu table, linking each meal to its restaurant via the restaurant number.

Explore working with multiple tables and foreign keys by linking menu and list through primary keys and references in a restaurant database. Understand keys and indexes that enforce table relationships.

Create a travel database, build a planes table with an integer primary key number and 25-character country_start and country_arrival columns, insert sample flights, then view results with a select.

Master the select tool to visualize and query data: pick columns, order results by country start or country arrival, and apply limits or rename columns.

Learn to rename a column and select specific columns in SQL using the select statement, including aliasing with as and choosing the source table.

visualize and link multiple tables in SQL by creating a second table with a foreign key referencing the primary key of planes, populating data, and generating a side-by-side visual view.

Learn to query and filter data with SQL using where clauses, numeric comparisons, and text matching, including pattern searches with like and contains.

Explore sql table modification with update statements, using set and where to change specific rows. See an example updating a column to 'no' where the row meets a condition.

Explore advanced SQL querying with where, like, and, or, and between to filter data across multiple conditions, and learn how to delete specific rows from a table.

Combine two related tables using left, right, and inner joins to reveal relationships between primary and foreign keys, illustrated by flight data linking planes and types.
