MySQL 1073: BLOB column can't have a default value.

When encountering the error "1073: BLOB column can't have a default value" in MySQL, the immediate action to take is to remove the default value assignment from the BLOB column definition in your table schema. MySQL does not support default values for BLOB and TEXT columns. Here is what you can do:

  1. Identify the table and column causing the issue by reviewing the SQL statement that triggered the error.



  1. Modify the table structure to remove the default value from the BLOB column. You can use the `ALTER TABLE` command for this. Suppose your table is named `mytable` and the BLOB column is `myblob_column`, the SQL command would be:



ALTER TABLE mytable MODIFY COLUMN myblob_column BLOB;

This command changes the column definition to remove the default value, ensuring it complies with MySQL's restrictions on BLOB columns.

  1. If necessary, adjust your application logic to handle the absence of a default value for this column, possibly by ensuring that a valid value is always provided for inserts or updates to this column.



These steps should resolve the error and allow your database operations involving the affected table and column to proceed without issue.
