Writing Queries

The information you want to present in any application is spread across multiple tables in a database. Queries play a vital role in collecting data from different tables and consolidating it for display.

With queries, you can perform various operations such as data insertion, updating, or removal from the database. Furthermore, queries enable data binding to widgets and offer additional functionalities that enhance the overall performance and user experience of the application.

This section talks about the steps to create a database query in the query editor:

  1. Once you are done with configuring database connector. It will show in the connectors' list. Click on the Add Query button.
Add Query
Click on ADD QUERY to open query editor.
  1. The query editor will open. You need to provide a name for the query and then write MySQL queries (Since here MySQL database is taken as an example.) underWrite Your Query.

DronaHQ provides specialized query editors for different databases, such as MySQL and MongoDB. These

database-dependent query editors enable users to write queries that are optimized for specific database systems, ensuring efficient and precise data manipulation. :::

effortlessly using natural language prompts. This exceptional functionality allows users to generate database queries with ease, making the process much faster and more user-friendly. :::

  1. Write a query, let's say to fetch all the details from a table in the database. After that, click Test Quey.

Making Queries Dynamic

In the realm of database connections, the key factor lies in the manner in which we execute queries.

In certain situations, such as when retrieving order details for products in a shop, there may be a need to obtain specific details for different products each time. To achieve this, dynamic inputs can be utilized. By incorporating dynamic parameters into the query, it becomes possible to fetch data from the data source based on the specific product details desired. This approach allows for flexibility and enables the retrieval of product details by passing dynamic parameters whenever required.

In DronaHQ's Query Builder, it is possible to accomplish this by creating variables using {{ }} notation when adding a query to a configured datasource connector, (It can be database or API connector). These variables can then be utilized to pass dynamic parameters to queries through various methods, such as forms, data, user-input, and more, within the App.

Let's see how to pass parameters to database query:

For Example, suppose we need to retrieve data from a table based on a particular order ID. However, we want this order ID to be dynamic and passed as a parameter to the query of the database connector.

As shown in the image above, the orderid has been transformed into a dynamic variable. Consequently, you can conveniently provide parameter values from the app by utilizing keywords.
