The most restrictive among the following is . . . . . . . .

mysql_query(), mysql_real_query()

Solution (By Examveda Team)

This question is about two MySQL functions: mysql_query() and mysql_real_query().

The question asks which one is more restrictive, meaning which one has more limitations or constraints.

Here's a breakdown: * mysql_query() is a more convenient function. It handles both data retrieval and command execution. However, it's less flexible because it automatically escapes input values, which can sometimes be problematic if you need to execute queries that contain special characters. * **mysql_real_query() provides more control. It allows you to directly pass your query string without any automatic escaping. This gives you more flexibility but requires you to handle escaping manually to prevent SQL injection vulnerabilities.
Therefore, the answer is Option B: mysql_real_query() because it's more restrictive due to its lack of automatic escaping and the need for manual handling of special characters.
