What are the Maximum Data Length Limits for BLOB, MEDIUMBLOB, and LONGBLOB Columns in MySQL?

Determining the Maximum Data Length for BLOB Columns in MySQL

MySQL provides the BLOB data type for storing large binary objects. Understanding the maximum capacity of a BLOB column is crucial for optimal database design.

BLOB Storage Limits

BLOB column storage space is subject to the following maximum limits:

• BLOB: 65535 bytes (64 KB)
• MEDIUMBLOB: 16777215 bytes (16 MB)
• LONGBLOB: 4294967295 bytes (4 GB)

Considerations for Larger Data Sets

If your data exceeds the BLOB limit, consider using MEDIUMBLOB or LONGBLOB based on your storage needs. These data types provide increased capacity for larger binary objects.
