How to use SQL statements?

Navicat provides an easy-to-use SQL editor that allows users to execute SQL statements. Using SQL statements, users can create, retrieve, update, and delete data from a database.

Specific steps:

1. Open SQL Editor: Click the SQL Editor icon in the toolbar or press F5.
2. Write SQL statements: Enter SQL statements in the editor.
3. Execution statement: Click the "Execution" icon in the toolbar or press F9.

Query example:

For example, to retrieve all employee information, you can use the following SQL statement:

 <code class="sql">SELECT * FROM employees;</code>

Other operation examples:

• Create a table:

   <code class="sql">CREATE TABLE customers (id INT, name VARCHAR(255), email VARCHAR(255));</code>

• Insert data:

   <code class="sql">INSERT INTO customers (id, name, email) VALUES (1, 'John Doe', 'john.doe@example.com');</code>

• Update data:

   <code class="sql">UPDATE customers SET name = 'Jane Doe' WHERE id = 1;</code>

• Delete data:

   <code class="sql">DELETE FROM customers WHERE id = 1;</code>

hint:

• Use the correct uppercase and lowercase letters because SQL is case sensitive.
• If you carefully check the syntax of the statement, syntax errors will cause execution to fail.
• Use appropriate quotes and escape characters.
• Consider using parameterized queries to prevent SQL injection.
