Master SQL through a three-step method that builds core concepts of structured query language across databases like MySQL, MariaDB, SQL Server, Oracle, and Postgres, emphasizing consistent logic despite small differences.
Explore how SQL, a structured query language, stores, defines, manipulates, and retrieves data in relational databases, and creates and drops databases and tables for web and mobile apps.
Start and manage database services using a control panel, launching the Apache web server and the MySQL (MariaDB) server with the default port 3306, and monitor process IDs.
Create your first database tables by defining an id integer, a name varchar(30) not null, and optional grade and degree fields, then set a primary key in a student table.
Master the drop table command by removing a table and verifying with a select. Then use insert into to add new rows to a table in your database.
Create a new table from an existing one using a select statement to copy all data. Learn how the select returns a result set to populate the new table.
Master the where clause to filter records in select statements, using conditions with integers and quoted strings to retrieve specific rows from a single table.
Learn to delete records with delete from students where name is equal to Chris, and also delete all records from a table by omitting the where clause.
Learn how to limit query results across mysql, mssql, and oracle using limit, top, and rownum with the same underlying logic.
