Question
Which of the following is an incorrect statement?Question 33Select one:a.Access plans for dynamic SQL statements are generated only at runtime.b.Dynamic SQL applications are slower than static SQL applications.c.The access plan generated for a static SQL statement is stored in advance.d.If the static SQL part of the application is modified, then the regeneration of access plans is not needed.
Solution
The incorrect statement is:
d. If the static SQL part of the application is modified, then the regeneration of access plans is not needed.
Explanation: When the static SQL part of an application is modified, the access plans need to be regenerated. This is because the access plan, which is the path that the database manager takes to execute an SQL statement, may change based on the modifications in the SQL statement. Therefore, it is necessary to regenerate the access plan to ensure that the database manager is using the most efficient path to execute the modified SQL statement.
