How can I create a dynamic table name in SQLite securely?

Dynamic Table Creation in SQLite

In SQLite, variable table names are not directly supported. However, there are techniques to achieve a similar effect while maintaining security.

Avoid Constructors

Using string constructors to create table names is not recommended due to the risk of SQL injection attacks. Consider using a sanitization function to remove special characters from the variable before constructing the table name.

Scrubbing Function

An example of a scrubbing function is provided below:

def scrub(table_name):
    return ''.join(chr for chr in table_name if chr.isalnum())

This function filters out non-alphanumeric characters from the table name.

Usage

To create a table with a dynamically determined name, you can use the following approach:

table_name = scrub(self.name)
cursor.execute("CREATE TABLE StarFrame" + table_name + " (etc etc)")

This ensures that the table name is safe from potential injection attacks.
