Answer 1

### The SQL query will read the '; after Boston as the end of the query and will then run the command to drop the table. Proper sanitization of database inputs should prevent this from happening.

Answer 2

## Step1: Understanding SQL Injection
### SQL injection is a code injection technique that attackers use to exploit vulnerabilities in a web application's database layer. They insert or "inject" malicious SQL statements or code that manipulates the database.
## Step2: Identifying the Attack Vector
### In the given 'city name', 'Boston'; DROP table OrdersTable--, the '; after Boston is interpreted as the end of the SQL query by the database system. This is because SQL queries are terminated by a semicolon (;).
## Step3: Execution of the Attack
### The 'DROP table OrdersTable--' part of the 'city name' is a malicious SQL statement that would delete the 'OrdersTable' from the database. The database system would execute this command as it is part of the SQL query.
## Step4: Prevention of SQL Injection
### To prevent such attacks, it is crucial to sanitize all database inputs. This involves cleaning the input data to remove any potentially harmful code or characters before it is used in a SQL query.
