How to Delete a Database Table with Data Patch Interface in magento2:-

Hello magento friends in this blog post i'm share with you to How to Delete a Database Table with Data Patch Interface in magento2. friends In Magento 2, you can delete a database table with data using the Data Patch interface. Data patches are a way to make database schema and data changes in a module. Here's how you can create a data patch to delete a database table:-

First steps is Create a new module or use an existing one:-

friends If you don't already have a custom module, you can create one in the app/code directory of your Magento installation. Make sure your module is enabled.

Second steps is Create a new PHP class for your data patch:-

friends In your magento2 project module's directory, create a new PHP class that implements the Magento\Framework\Setup\Patch\DataPatchInterface interface. This class will contain the logic to delete the database table.

// app/code/YourVendor/YourModule/Setup/Patch/DeleteTable.php

<?php

declare(strict_types=1);

namespace YourVendor\YourModule\Setup\Patch;

use Magento\Framework\Setup\Patch\DataPatchInterface;

use Magento\Framework\Setup\Patch\PatchRevertableInterface;

use Magento\Framework\Setup\Patch\SchemaPatchInterface;

use Magento\Framework\Setup\Patch\UpdatePatchInterface;

use Magento\Framework\Setup\SchemaSetupInterface;

use Magento\Framework\Setup\ModuleDataSetupInterface;

class DeleteTable implements DataPatchInterface, PatchRevertableInterface

{

    /**

     * @var ModuleDataSetupInterface

     */

    private $moduleDataSetup;

    public function __construct(

        ModuleDataSetupInterface $moduleDataSetup

    ) {

        $this->moduleDataSetup = $moduleDataSetup;

    }

    public static function getDependencies(): array

    {

        return [];

    }

    public function getAliases(): array

    {

        return [];

    }

    public function apply()

    {

        $this->moduleDataSetup->getConnection()->startSetup();

        try {

            $this->deleteTable();

        } catch (\Exception $e) {

            // Handle any exceptions or errors

        }

        $this->moduleDataSetup->getConnection()->endSetup();

    }

    public function revert()

    {

        $this->moduleDataSetup->getConnection()->startSetup();

        try {

            // If needed, implement the revert logic here

        } catch (\Exception $e) {

            // Handle any exceptions or errors during revert

        }

        $this->moduleDataSetup->getConnection()->endSetup();

    }

    private function deleteTable()

    {

        $connection = $this->moduleDataSetup->getConnection();

        $tableName = $connection->getTableName('your_table_name'); // Replace with your table name

        if ($connection->isTableExists($tableName)) {

            $connection->dropTable($tableName);

        }

    }

}

Keep in mind friends in here given above code Replace 'your_table_name' with the name of the table you want to delete.

Run the patch file, After creating the data patch class file, you need to apply it using the following command:-

bin/magento setup:upgrade

in this magento this command will execute the apply() method of your data patch, deleting the specified table. friends Remember to replace YourVendor name and YourModule name with your actual vendor and module names. Always make sure to backup your database before making any structural changes, and test thoroughly on a development environment before deploying to production.
