Can PDO Bind Table Names in SQL Queries?

PDO Bind Table Name

Question:

Can PHP Data Objects (PDO) bind a table name to an SQL query?

Answer:

No, it is not possible to bind a table name to an SQL query using PDO.

Explanation:

PDO operates by binding values to parameters in prepared statements, ensuring that the inputs are treated as data and not as a part of the SQL statement itself. Table names, however, are considered part of the SQL structure, and binding them would present a security risk as it would allow users to manipulate the database structure dynamically.

Solution:

Instead of binding table names, consider the following alternative approaches:

• Whitelisting: create a list of authorized table names and validate user input against this list to prevent unauthorized access.
• Encapsulation: encapsulate table access in a class or library that restricts access to authorized tables through its internal implementation.
• Parameterization: pass the table name as a function argument or object method argument instead of binding it to a query parameter.
