In MyISAM tables, when a table is emptied with the TRUNCATE TABLE, the counter begins at . . . . . . . .
Answer & Solution
Correct Answer:
Option
B
This question is about how MySQL handles the auto-increment counter in MyISAM tables when you use the `TRUNCATE TABLE` command.
The `TRUNCATE TABLE` command is used to delete all rows from a table.
In MyISAM tables, the auto-increment counter is a special value that helps MySQL assign unique IDs to new rows. When you add a new row, the counter is increased by 1, and the new row gets the current value of the counter.
The question asks what happens to the counter when you use `TRUNCATE TABLE`.
The answer is Option A: 0
When you truncate a table, MySQL resets the auto-increment counter to 0. This ensures that when you start adding new rows again, they will receive unique IDs starting from 1.
