Which mode does not remove trailing spaces when CHAR values are retrieved?

Solution (By Examveda Team)

This question is about how MySQL handles spaces in CHAR data types. CHAR columns store fixed-length strings, meaning they always occupy the same amount of space, even if the actual text is shorter.

To fill up the empty space, MySQL uses padding. This padding can be either spaces or null characters (which are invisible).

Let's look at the options:
* Option A: PAD_CHAR_TO_FULL_LENGTH: This mode pads the CHAR values with spaces to fill the full length of the column. This means trailing spaces will be added.
* Option B: TO_FULL_LENGTH_CHAR_PAD: This is the same as PAD_CHAR_TO_FULL_LENGTH, so trailing spaces will be added.
* Option C: CHAR_PAD_TO_FULL_LENGTH: This is another way of saying PAD_CHAR_TO_FULL_LENGTH, and trailing spaces will be added.
* Option D: PAD_CHAR_TO_LENGTH: This mode also pads CHAR values to the full length of the column. This is the same as the other options.

So, the answer is none of the above. There is no mode that does not remove trailing spaces when retrieving CHAR values. All these modes pad the values to the full length using spaces.
