Can MySQL TEXT Columns Have Default Values?

Default Values for TEXT Columns in MySQL

Question:
Why is it not possible to assign default values to TEXT columns in MySQL?

Answer:

Contrary to the given statement, assigning default values to TEXT columns is allowable in MySQL. However, due to a discrepancy between Windows and other operating systems, this action triggers an error on Windows platforms.

While Linux and other platforms raise a warning for this behavior, Windows MySQL v5 throws an error. This inconsistency arises from differences in MySQL's sql-mode settings.

Resolution:

To disable strict mode in MySQL 5 (Windows) and allow default values for TEXT columns, follow these steps:

  1. Edit the /my.ini file and locate the line:

    sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
    Copy after login
  2. Replace it with:

    sql_mode='MYSQL40'
    Copy after login
  3. Restart the MySQL service (net stop mysql5 and net start mysql5).

Alternatively, if you have root/admin access, you can execute the following query:

mysql_query("SET @@global.sql_mode='MYSQL40'");
Copy after login
