This allows the AppSheet server to connect directly to your database. Enter the IP addresses listed in Manage IP addresses and firewall information.By checking this box, Google Cloud will create an IP address that you can use to connect your AppSheet account to the database instance.
Under Connectivity ensure Public IP is checked.Click Show configuration options to expand the configuration options.For best performance, select between these two regions based on where the majority of your users are located. AppSheet servers are located in us-west and europe-west. This is how your database will be identified in the Google Cloud account. Open your Google Cloud account and click SQL in the left menu.In summary, a database instance can have multiple databases and a database can have multiple tables. When viewing a form in AppSheet, each field in the form corresponds to a column in the table and saving the form creates a new row. A table generally has several columns, each with a specific type of data (such as, Name, email address, phone number, and so on). Database is the term used in Google Cloud and AppSheet. Schema is the term used in MySQL Workbench. It is a collection of data made up of several tables. Schema: In this context, schema and database are referring to the same thing.In AppSheet, each database will appear as an individual data source. A database generally holds several tables. Database: A database is a collection of data.In the tutorial below, you will generate a public IP address to connect with the database instance. Database Instance: The database instance is the structure that manages a collection of database files.The following list defines a few terms with a focus on how they are used in relation to AppSheet. Access to a Google Cloud Platform account.An AppSheet plan that supports database connections.You can also select the database after login into the MySQL Workbench by using Set as Default Schema feature or by issuing the USE statement. If you are using the MySQL Workbench application to connect MySQL instance, you can select a database by specifying the database name in the Default Schema: text box as shown in the following screenshot. ERROR 1049 (42000): Unknown database 'customerdb' Selecting a database in MySQL Workbench

This will display the output as below: +-+ After successful login, you can then check the current database using the following statement. You give the correct root password and press enter. Same as before, this will ask for MySQL root password. In this method, you can specify the name of the database while logging into the MySQL server using the Command Line tool by mentioning the -D flag followed by the database name.įor example, if you want to select the companydb as the default database, you specify the companydb after the -D flag as below: mysql -u root -D companydb -p There is another way to select a database in MySQL.

Now, check the current database using the following statement. If everything goes well then you will see mysql> on the screen. You give the correct root password of the MySQL server and press enter.
Let’s check:įirst, log in to the MySQL server Command Line Client tool using root user. Generally, when you logged into the MySQL Command Line tool without specifying the default database name, MySQL sets the current database to NULL. 1) Selecting database using MySQL Command Line tool This is because there might be more than one databases in the MySQL Server.
