MySQL

MySQL is a powerful open-source relational database management system known for its speed, reliability, and flexibility, making it a popular choice for various applications and data-driven projects.

Configuring Connector

Prerequisites

1. Authentication Credentials: Obtain the required credentials to connect to your MySQL instance. Choose from the following options:

   • MySQL database username and password.
   • AWS IAM authentication (for AWS-hosted MySQL databases).

2. Connection Details:

   • Hostname of the MySQL database.
   • Port number for database access.
   • Database name within the MySQL host.

3. Firewall Rules:

   • Set up firewall settings to allow DronaHQ (IP whitelist) access to your MySQL host.

Ensuring these prerequisites are in place will ensure a seamless integration of MySQL with DronaHQ, facilitating effective data management and utilization.

Connector Setup in DronaHQ

Configure your database category by providing the details below. Choose between User and Password or AWS IAM Authentication. Validate the connection using Test connection and Save settings for a secure and efficient database setup.

tip

DronaHQ can Auto fill crucial connection values like host, name, password, and more from the connector's connection string or from a AWS IAM credentials using AWS Import.

General

Field	Description
Host	Enter the Host Domain or IP
Port	Enter the Port number
Database Name	Enter the Database name

MySQL with Sample details.

Admin

Advanced Option	Description
Connection Options	The key and value connection options in MySQL configuration refer to specific settings (keys) and their corresponding values that dictate how the application connects to the database
Use Dynamic Database Host	Dynamically determine the host for the database connection.
Use Dynamic Database Name	Set the database name dynamically, allowing easy switching between databases.
Use Dynamic Database Credentials	Enable dynamic database credentials for secure and convenient management.
Enable Converting Queries to Prepared Statement	Opt for prepared statements to enhance database performance and security.
Connect using SSL	Securely access the database using an encrypted SSL connection, ensuring data integrity and confidentiality.
Enable SSH Tunneling	Securely access the database through encrypted SSH tunneling.
Whitelist IP	Enhance security by restricting database access to specific whitelisted IP addresses.

Adding Database Queries

Once the connector is configured, access it in your Connector Library. Click Add query after connection setup. Create queries, run them, and view responses.

Write Queries

tip

Use double curly brackets for dynamic variables. Test with sample values before saving. Link dynamic variables to controls/actions for runtime use.

Saved queries appear under your connector in Connector Library.

Supported Query Operations

Operations	Description
Raw SQL Query	Various select, insert, delete, update, join operations.
Stored Procedure Call	Call stored procedures e.g., CALL getUserInfo;

Using MySQL Connector

Data Bind using Data Query

Read/Display Data Query for MySQL:

Start by constructing an SQL query to extract data from your MySQL database. For instance, let's consider an example where you want to retrieve data from the Authors table based on specific initials. The SQL query is:

Query used:

SELECT * FROM Authors WHERE initials = "{{SearchInitials}}";

Query explanation:

This SQL query retrieves all rows and columns from the Authors table where the initials match the value provided through the dynamic variable {{SearchInitials}}.

Get data query with dynamic variable.

Integrate the fetched data into your application's interface.

a. Access the Controls section and introduce the Table grid control.

b. Navigate to Data Bind Options -> Quick Select -> Database Queries.

c. Opt for the MySQL connector and choose the query that aligns with your data presentation goals.

By following these steps, you can seamlessly retrieve and display data from the Authors table based on specific initials using the MySQL Connector, enhancing your application's functionality and user experience.
