This page provides information for connecting your application to your MySQL database and for using queries to manage its content.

Appsmith supports MySQL versions 5.5, 5.6, 5.7, and 8.0.

Connect MySQL


If you are a cloud user, you should whitelist the IP address of the Appsmith deployment and on your database instance or VPC before connecting to the database.

Connection parameters

The following section is a reference guide that provides a complete description of all the parameters to connect to a MySQL database.

MySQL Datasource configuration page
Configuring a MySQL query.

MySQL databases are queried using standard SQL syntax. For a language reference, see MySQL's Language Structure.

Fetch data

SELECT * FROM users LIMIT {{ UsersTable.pageSize }} OFFSET {{ UsersTable.pageOffset }};

In the above example, UsersTable is the name of the Table widget used to display the data using server-side pagination to control how much data is queried at once.

Insert data

(name, gender, email)
{{ NameInput.text }},
{{ GenderDropdown.selectedOptionValue }},
{{ EmailInput.text }}

In the above example,  NameInputGenderDropdown, and EmailInput are the names of the widgets used to capture input from the user for name, gender, and email fields, respectively.

Update data

UPDATE users
SET email = {{ EmailInput.text }}
WHERE id = {{ }};

In the above example, EmailInput is the name of the Input widget used to capture the email entered by the user. UsersTable is the Table widget where the user selects the row to update the user's email.

Delete data

DELETE FROM users WHERE id = {{ }};

In the above example, UsersTable is the name of the Table widget where the user selects the row for deletion.


Prepared statements are turned on by default in your queries to help prevent SQL injection attacks. For more details, see Prepared Statements.

SQL modes

SQL_MODE is a system variable in MySQL that can:

  • Configure the server's strictness when accepting input data,
  • Adjust syntax to conform more closely to standard SQL,
  • Provide better compatibility with other databases.

In particular, strict mode can help you ensure the integrity of your data by preventing the database from automatically inserting default values for missing or invalid data.

For more information, see the docs for MySQL's SQL Modes.
