As we know that BLOB is a binary large object that can hold a variable amount of data. The different TEXT objects offer a range of storage space from 255 bytes to 4 Gb. Following table shows the storage of different kinds of BLOB data type −
Type of BLOB | Maximum amount of Data that can be stored | Overhead |
TINYBLOB | Up to 255 bytes | 1 byte |
BLOB | Up to 64 Kb | 2 bytes |
MEDIUMBLOB | Up to 16 Mb | 3 bytes |
LONGBLOB | Up to 4 Gb | 1 Bytes |
