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:
-
Edit the /my.ini file and locate the line:
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
-
Replace it with:
sql_mode='MYSQL40'
- 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'");

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
