In this blog, we’re going to show you how to use the db_schema.xml file to create a new database table.

Once you Create file db_schema.xml in this directory app/code/VName/MName/etc. We will create a table named  “table_name”.

<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
     <table name="table_name">
       <column xsi:type="int" name="id" padding="10" unsigned="true" nullable="false" comment="Entity Id"/>
       <column xsi:type="varchar" name="title" nullable="false" length="255" comment="Title"/>
       <column xsi:type="timestamp" name="time_occurred" comment="Time of event"/>
       <column xsi:type="int" name="status" nullable="false" default="0" comment="status"/>
       <column xsi:type="mediumtext" name="description" nullable="true" comment="Description"/>
       <constraint xsi:type="primary" referenceId="PRIMARY">
        <column name="id"/>
        </constraint>
     </table>
</schema>

After will running the below command :

• php bin/magento setup:upgrade

As you run the upgrade command, a new database table will be created in your database.
