The 'LAST_INSERT_ID()' is tied only to the 'AUTO_INCREMENT' values generated during the current connection to the server.
A. True
B. False
Answer: Option A
Solution (By Examveda Team)
This question is about how MySQL handles the LAST_INSERT_ID() function, which is used to get the ID of the last row inserted into a table.The Question:
Does the LAST_INSERT_ID() function only remember the ID from the last insert done within the same connection to the database server?
Understanding the Options:
* Option A: True - This means that if you close the connection to the MySQL server and then open a new connection, the LAST_INSERT_ID() function will not remember any previous inserted IDs. It will only work for the current connection. * Option B: False - This means that the LAST_INSERT_ID() function will remember the last inserted ID across different connections, even if you close and re-open the connection.
The Answer:
The correct answer is Option A: True. The LAST_INSERT_ID() function is tied to the current connection. It only remembers the last AUTO_INCREMENT value generated within that connection. When you close the connection, it forgets that value.
Example:
Imagine you insert a new row into a table using one connection. Then you close that connection and open a new one. If you use LAST_INSERT_ID() in this new connection, it won't return the ID of the row you inserted earlier because it's a different connection.
