9. Which of the following area of PGA stores binding variables and run-time buffers information?a) Stack spaceb) SQL areac) Session aread) Private SQL area

To determine which area of the PGA (Program Global Area) stores binding variables and run-time buffers information, let's analyze the options provided:

1. Stack space: This typically pertains to memory allocated for function calls and local variables. It does not store binding variables or run-time buffers related to SQL execution.

2. SQL area: This is used to store the parsed representation of SQL statements, but it does not specifically store binding variables or run-time buffer details.

3. Session area: This involves storing session-level information, including user-related data, but again, it does not specifically pertain to binding variables and run-time buffers.

4. Private SQL area: This is where the execution plan and run-time information about a specific SQL statement is stored. It also includes binding variables and run-time buffers.

Final Answer

The correct answer is d) Private SQL area. This area is responsible for storing binding variable information and run-time buffers necessary for the execution of SQL statements.
