How do you set a default value for a MySQL Datetime column?

📝 Title: The Ultimate Guide to Setting Default Values for MySQL Datetime Columns 🗓️

Hey there, tech enthusiasts! 👋 Are you struggling with setting a default value for a MySQL Datetime column? 🤔 Don't worry, you're not alone! Today, we'll explore this common issue and provide you with easy solutions. Let's dive in! 💡

⚠️ The Common Issue: How do you set a default value for a MySQL Datetime column? 🗒️

Setting a default value for a MySQL Datetime column is a piece of cake, my friends! 🍰 While in SQL Server, we use getdate() for this purpose, in MySQL, we can achieve the same result using the CURRENT_TIMESTAMP() function. If you're using MySQL 5.x or above, this is the way to go! 🙌

🔥 Easy Solution #1: ALTER TABLE Statement

Your first solution is to modify your table using the ALTER TABLE statement. Let's take a look at the syntax:

ALTER TABLE your_table_name 
    ALTER COLUMN your_column_name 
    SET DEFAULT CURRENT_TIMESTAMP();

In this example, replace your_table_name with the name of your table and your_column_name with the name of your Datetime column. Once executed, any new rows inserted into this table without providing a value for the Datetime column will automatically default to the current timestamp. 📅

🔥 Easy Solution #2: DEFAULT Keyword During Table Creation

Another way to set a default value for your Datetime column is to utilize the DEFAULT keyword when creating your table. Yeah, you heard that right! Let's check out the syntax:

CREATE TABLE your_table_name (
    your_column_name DATETIME DEFAULT CURRENT_TIMESTAMP(),
    other_columns...
);

By using this method, you will declare the default value for your Datetime column right from the beginning. New rows added to the table without explicitly setting a value for the Datetime column will adopt the current timestamp automatically. How easy is that? 💪
