If you're looking to generate test data for your database quickly and efficiently, Navicat offers a built-in tool that makes this process straightforward. Whether you're testing performance, building prototypes, or preparing for demos, using Navicat's data generation feature can save you time and effort.

Use the Data Generation Tool in Navicat

Navicat provides a Data Generation feature (available in Navicat Premium and some edition-specific versions) that allows you to automatically populate tables with realistic sample data. This is especially useful when you need to simulate real-world usage without manually inserting records.

To get started:

• Open Navicat and connect to your database.
• Navigate to the table you want to fill with test data.
• Right-click on the table and choose Generate Test Data .
• You'll be presented with a configuration screen where you can specify the number of records and customize field values.

You don't need any SQL knowledge to use this tool — it's all done through a user-friendly interface.

Customize Fields Based on Data Types

One of the key strengths of Navicat's data generator is its ability to intelligently suggest values based on column types. For example:

• Integer columns might be filled with sequential or random numbers.
• Date fields can be populated with dates within a specified range.
• String fields can contain realistic names, emails, addresses, etc.

You can also override these defaults by choosing from a list of generators per field. For instance:

• Use "Full Name" generator for a VARCHAR column storing names.
• Select "City" or "Country" if you're populating location-based data.
• Choose "Email" or "Phone Number" for contact info fields.

This level of customization ensures that your test data looks authentic and fits the expected format of your application.

Generate Data for Multiple Tables at Once

If you have several tables that need test data, Navicat lets you handle them together. From the Tools menu, select Generate Test Data , then pick multiple tables. You can set the same number of rows for all or adjust individually.

This batch approach helps maintain consistency across related tables, especially when dealing with foreign key constraints. Just make sure the relationships are correctly defined so that referential integrity is preserved during generation.

That's how you can generate test data using Navicat. It's not complicated, but knowing which options to use can make a big difference in how realistic and useful your test data ends up being.
