- Choose an editor that fits your needs (i.e., one that offers free access).
Creating a Database
Once you’re in the editor, you can create a new database. Here is a simple command to create a database:
CREATE DATABASE SchoolDB;
Writing SQL Queries
You can write SQL queries directly in the editor’s query window. After writing your queries, simply hit the “Run” button to execute them and see results.
SQL Syntax
SQL, or Structured Query Language, is used for managing and manipulating databases. Understanding the basic SQL syntax is crucial for success while using the MySQL Online Editor.
Explanation of SQL Commands
| Command | Description |
|---|---|
| SELECT | Retrieve data from the database. |
| INSERT | Add new records to a table. |
| UPDATE | Modify existing records. |
| DELETE | Remove records from a table. |
Common SQL Syntax Used in the Editor
Here are a few commonly used SQL syntax examples:
SELECT * FROM Students;
INSERT INTO Students (name, age) VALUES ('John Doe', 18);
UPDATE Students SET age = 19 WHERE name = 'John Doe';
DELETE FROM Students WHERE name = 'John Doe';
Example Queries
To give you a better understanding, here are some practical examples of SQL queries:
Basic SELECT Queries
You can retrieve data using a simple SELECT query:
SELECT name FROM Students;
INSERT, UPDATE, and DELETE Examples
Adding a new student record:
INSERT INTO Students (name, age) VALUES ('Jane Smith', 20);
Updating an existing student’s age:
UPDATE Students SET age = 21 WHERE name = 'Jane Smith';
Deleting a student record:
DELETE FROM Students WHERE name = 'Jane Smith';
Practical Application of Queries
Understanding the practical application of these queries can help when handling actual database systems. For instance, if you’re managing school records, you’ll often use SELECT to show student lists, INSERT to add new students, and DELETE to remove students from the records.
