Length byte
NettetThe length prefix indicates the number of bytes in the value. A VARCHAR column uses one length byte if values require no more than 255 bytes, two length bytes if values may require more than 255 bytes. MariaDB follows the standard SQL specification, and does not remove trailing spaces from VARCHAR values. NettetA fixed-length data type is a specified length that cannot be changed. Table 1shows the rules for generating the fixed-length data types. If repeat is not requested and length is not specified, the data types are mapped as shown here. Table 1. by language Table 2shows the fixed-length data types generated as arrays where length is applicable
