Magento 2 DB Schema Rename Column | Guide

If you are using Magento 2 and you have to rename a column in a database table, you are in luck. Today, our experts will take you through the process with a few simple steps.

We will be able to successfully rename columns in our Magento 2 database tables in no time.

1. First, we have to create a custom module or extension in Magento 2. Within this module, we can generate a database patch or upgrade script that has the required code to execute the column renaming task.
2. Then, we must identify the table which has the targeted column and note its exact name. We need this information for the renaming process.
3. Next, we have to utilize the Magento schema setup object to manipulate the database schema effectively, within our patch or upgrade script.

   We can use the renameColumn() method to specify the table name, the current column name, and the desired new column name. By including this in our script, we can easily rename the column within our Magento 2 database table.

Alternatively, once we add a column in the table, we can easily rename it via the UpgradeSchema.php file.

For instance, suppose we add a field named guestname to the sales_order table, and we want to rename it to fullname. We can get this done by implementing the changeColumn() method within the UpgradeSchema.php file.

In other words, we have to upgrade the setup_version number of the module in the module.xml file. Then, create the UpgradeSchema.php file under the Setup folder in our module, where we include the code snippet seen below.

At the end of the day, renaming columns in Magento 2 database tables offers us the flexibility and adaptability necessary to maintain a reliable e-commerce platform.
