What is the maximum length for an enum value, i.e. a string literal?

Answer 1

The limit does not apply to the length of the literal string, but rather to the definition of the table.

The MySQL documentation states that

Each table has a .frm file that contains a table definition. The server uses the following expression to verify some table information stored in a file with an upper limit of 64 KB.

followed by an ad-hoc equation expressing the approximate size of a table definition.

63136 , .frm 71775 ( 70 ), . MySQL #1117 - Too many columns, , , .

// , . - , 1 .

Answer 2

ENUM 65 535 . ( 3000.) 255 ENUM SET, .
