MySQL BLOB Column Data Length Limits
The maximum data length that can be stored in a BLOB (Binary Large OBject) column in MySQL is 65535 bytes, equivalent to 64 KB. This length applies to the BLOB data before compression, as MySQL compresses BLOB data by default.
If you require storing larger data volumes, consider using these extended data types:
- MEDIUMBLOB: Can hold up to 16777215 bytes (16 MB) of data.
- LONGBLOB: Suitable for storing data up to 4294967295 bytes (4 GB).
For further details on storage requirements for string types in MySQL, consult the "Storage Requirements for String Types" documentation.
