To add an existing schema to MySQL on Windows, you can use the MySQL Command Line Tool. Start by opening the Command Prompt and logging in to MySQL with the command "mysql -u username -p". Enter your password when prompted.
Once logged in, select the database where you want to add the schema with the command "USE database_name". Then, use the source command to execute the SQL script that contains the schema definition. For example, if your SQL script is named "schema.sql" and located in the "C:\Users" directory, you can run the command "source C:/Users/schema.sql".
After executing the SQL script, the schema will be added to the selected database. You can verify this by running queries to check the tables, views, or other objects defined in the schema. Additionally, you can use tools like MySQL Workbench or phpMyAdmin to manage the schema and its objects more easily.
