AppSheet can build apps from MySQL databases that are hosted in the cloud, including Google Cloud SQL, Amazon RDS, Oracle MySQL Cloud Service, or other cloud-hosting provider that supports MySQL. Show
Use data from MySQL as described in the following sections: Add a MySQL data sourceBefore adding a MySQL data source, see . Note: In order for AppSheet servers to access your data, both the MySQL database's network and the MySQL database itself must accept inbound connections from AppSheet servers to the database. For more information, see Manage IP address and firewall information. To add a MySQL data source:
Configure SSLAppSheet can connect to MySQL instances using Secure Socket Layer (SSL). When adding a MySQL data source, select one of the following options: SSL mode Description None SSL connection is not required, although some cloud providers will still attempt to establish SSL, if possible. Required Data to and from the MySQL instance must be encrypted using the SSL protocol. Only the (owned by the MySQL instance) is required to establish the connection. The (normally stored in the application client) is optional. Note: If your MySQL instance is configured to use X.509 mode, you'll need to change the connection mode to SSL in order for the connection to work. For instances hosted on Google Cloud, X.509 mode can be turned off by going to the SSL tab and clicking Allow unsecured connections. This will relax the client certificate requirement. VerifyCa Data to and from the MySQL instance must be encrypted using the SSL protocol. Uses a client certificate to authenticate with the server. Additionally, verifies the server's CA with the provided CA certificate. This mode tolerates hostname mismatch. You are prompted to upload the following content:
Note: This mode is useful for the database servers that do not have a hostname but expose IP addresses for connections, such as Google CloudSQL. VerifyFull Data to and from the MySQL instance must be encrypted using the SSL protocol. This mode is the same as VerifyCa, but also matches the server hostname with the CA certificate. You are prompted to upload the following content:
When using an SSL connection, it's highly recommended that the MySQL instance uses a server certificate generated by a widely recognized certificate authority such as VeriSign or GeoTrust. This will ensure that the certificate meets all of the relevant encryption and formatting standards. Some cloud storage providers, such as Google Cloud and Amazon RDS, also generate server certificates for the MySQL instances that they host. Currently, server certificates generated by TinyCA are not supported. Additionally, it's a good practice to sign the server certificate using SHA-2 hashing algorithms. This is because SHA-1 algorithms are no longer considered fully secure, and many cloud providers, including Microsoft, Amazon, and Google, are increasingly moving to SHA-2 and SHA-3. Use a MySQL data source in your appAfter you add a MySQL data source to your account, you can add MySQL tables or views to any app. When you choose Add Table in your app, you can select the specific data source, and a table or view from that data source. Once added to the app, AppSheet treats all data sources similarly. In fact, it's common to combine data from a MySQL data source with data from other sources in the same app. Use MySQL on Amazon RDSIf your MySQL instance is hosted on Amazon RDS, you may need to set the Publicly Accessible setting to Yes. To ensure the server accepts traffic from AppSheet, go to security groups settings in Amazon RDS, enter the EC2 Management Console, choose Edit inbound rules, and create rules to accept all traffic from AppSheet's IP addresses, as described in Manage IP address and firewall information. Supported MySQL versionsFor your MySQL instance to work with AppSheet, we recommend that you use MySQL version 5.7.6 or above. In addition, because MySQL is open source, there are many variants of MySQL, such as MariaDB or Percona. If you use a variant of MySQL, AppSheet cannot guarantee that your database will work. Note: When working with a MySQL data source, if you encounter an How files created in the app are savedTypically, if an app has to capture photographs, for example, they are typically stored in a folder adjacent to the source of data in cloud storage. Unlike our other cloud-storage providers, database servers do not have a file system and require a change in AppSheet behavior when saving files (like images and documents). In a MySQL table, image and document files are stored in the main cloud file system associated with the app creator's primary AppSheet account (typically Google Drive, Dropbox, Office 365, or Box). The files will be saved in a subfolder of your account's default folder path (usually You can view and change the default folder path in your account page under the Settings tab. How required columns are setEach database column that specifies Work with IDENTITY columnsIt's common for a database table to use an Using We recommend that you avoid using 4 value of length greater than or equal to 8, such as 5. In AppSheet's column definition for this key, enter an initial value using 6. Using this method, unique key values can be assigned by the app and inserted into the backend database.If the database must use 8. In AppSheet's column definition for this key, give it an initial value of 9Unknown column error 0. This way, any records created from your app will have five-digit values that fall randomly in the range 10000 to 99999, while records created directly against the database will have higher values.If the database schema cannot be changed and if there is already an
This should "re-seed" the Work with special charactersA MySQL character set defines the characters that can be read and processed by a particular MySQL database or table. The default character set of a MySQL database should work with most Latin characters. However, many languages, such as Spanish or Chinese, have special characters that aren't included in the default character set. In order to work with these special characters, you'll need to configure your MySQL database or table to use the appropriate character set. For example, to configure an entire database to work with special characters in Spanish, such as ñ, use the following command:
Alternatively, to configure only a single table, use the following command:
More information about available character sets in MySQL can be found in the MySQL developer documentation: Apakah kita dapat merubah nama tabel dalam MySQL bagaimana query nya?Perintah SQL (Structured Query Language) yang dipakai untuk mengubah nama tabel dalam database MySQL adalah perintah RENAME TABLE. Dengan perinah ini Kita dapat menguba nama tabel A menjadi tabel B, atau sebaliknya.
Alter table MySQL untuk apa?ALTER: Perintah alter digunakan untuk melakukan perubahan struktur tabel yang telah dibuat. Misalnya, menambah Field (Add), mengganti nama Field (Change) ataupun menamakannya kembali (Rename), dan menghapus Field (Drop).
Apakah perintah yang berguna mengubah struktur sebuah tabel yang sudah terbuat?Perintah ALTER berfungsi untuk mengubah struktur tabel yang telah dibuat. Adapun diantaranya yakni mengubah nama tabel, menambah kolom, mengubah kolom, menghapus kolom, dan memberikan atribut pada kolom. Perintah DROP berfungsi untuk menghapus database dan tabel yang telah dibuat.
Jelaskan apa yang dimaksud dengan MySQL?MySQL atau dibaca My Sequel merupakan sebuah Database Management System atau sering disingkat DBMS yang dijalankan menggunakan perintah SQL (Structured Query Language) yang populer digunakan untuk pembuatan aplikasi berbasis website.
