I have created an extension with the schema. It is installed correctly and tables are created correctly in the database.

But, now I want to uninstall that extension.

But with uninstall, I also want to delete the tables which were created during the installation of the same extension.

is there any way to do this?

  • Login to your database , 1. run this query to show the table you want to delete is there show tables; , 2. run drop table table_name , 3 run query Delete from setup_module where module=Namespace_Module , 4 Flush magento cache. 5 php bin/magento cache:flush, php bin/magento setup:upgrade, php bin/magento setup:static-content:deploy Oct 3, 2018 at 14:28

For uninstalling the extension, you have to create a Setup/Uninstall.php file.

in that file for uninstall function, add following lines to drop your module table.

public function uninstall(SchemaSetupInterface $setup, ModuleContextInterface $context)
        if ($setup->tableExists('module_table_name')) {
