Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs

reason¶

When MySQL builds a table, there is a limit on the maximum length of a single row: the total number of bytes set in all fields in a table is not more than 65535 bytes

Note 1: A single field whose size exceeds 65535 is converted to text
Note 2: The sum of the remaining fields does not exceed 65535 bytes (excluding BLOB/TEXT)
Note 3: The database uses UTF-8 encoding, one character = three bytes in size
Example of an error: There are 10 varchar fields in the database, each of which has a size of 3000. The current calculated length of a single row in the database is 3000 * 10 * 3 = 90000> 65535.

solution¶

Set the large field type of the database table to TEXT, or reduce the length of the part that can be reduced to a total of less than 65535
