### SQL Injection

Use `' OR 1=1; --`  
Use `tohyouxuan@gmail.com' UNION SELECT id, email, password FROM users WHERE email = 'tohyouxuan@gmail.com'; --`

#### 1. Parameterization of Queries

Used `pool.Query()` with a parameterized query, instead of dynamically constructing the SQL query by directly inserting the user input.  
Parameterized queries separate the SQL code from the data, so user input is never directly put into the query's structure. Placeholders are used instead, and the data is passed as parameters. The DB will treat them as data, not executable code.
