The maximum length of the varchar columns is . . . . . . . .

Solution(By Examveda Team)

In MySQL, the VARCHAR data type is used to store variable-length character strings. We need to determine the maximum length allowed for VARCHAR columns.

The correct option is Option A: Upto 65,535 bytes.

Upto 65,535 bytes: In MySQL, the maximum length of VARCHAR columns is 65,535 bytes. This limit applies to the maximum size of the column in terms of bytes, not characters. The actual number of characters that can be stored may be less depending on the character set and encoding used. For example, if the UTF-8 character set is used, some characters may require more than one byte to store, reducing the maximum number of characters that can be stored in the VARCHAR column.
Upto 256 bytes: This option is incorrect. While VARCHAR columns have a maximum length, it is much larger than 256 bytes.
Upto 65,567 bytes: This option is incorrect. The maximum length of VARCHAR columns is not 65,567 bytes. The correct limit is 65,535 bytes.
None of the mentioned: This option is not correct. The maximum length of VARCHAR columns in MySQL is specified and can be determined.

Therefore, the maximum length of VARCHAR columns in MySQL is Option A: Upto 65,535 bytes.
