ToolJet Database - Tooljet

Use the ToolJet-hosted database to build apps faster, and manage your data with ease. ToolJet database require no setup and give you a powerful user interface for managing your data.

Enabling the ToolJet Database for your instance

Requires:

PostgREST server
Additional configuration for ToolJet server

This feature is only enabled if ENABLE_TOOLJET_DB is set to true.

PostgREST server

PostgREST is a standalone web server that turns your PostgreSQL database directly into queryable RESTful APIs which is utilized for Tooljet Database. This server only talks with ToolJet server and therefore does not have to be publicly exposed.

:::tip If you have openssl installed, you can run the command openssl rand -hex 32 to generate the value for PGRST_JWT_SECRET.

If this parameter is not specified, PostgREST will refuse authentication requests. :::

variable	description
PGRST_JWT_SECRET	JWT token client provided for authentication
PGRST_DB_URI	database connection string for tooljet database
PGRST_LOG_LEVEL	`info`

:::info Please make sure that DB_URI is given in the format postgres://[USERNAME]:[PASSWORD]@[HOST]:[PORT]/[DATABASE] :::

Additional ToolJet server configuration

variable	description
ENABLE_TOOLJET_DB	`true` or `false`
TOOLJET_DB	Default value is `tooljet_db`
TOOLJET_DB_HOST	database host
TOOLJET_DB_USER	database username
TOOLJET_DB_PASS	database password
TOOLJET_DB_PORT	database port

If you intent to make changes in the above configuration. Please refer PostgREST configuration docs.

:::tip When this feature is enabled, the database name provided for TOOLJET_DB will be utilized to create a new database during server boot process in all of our production deploy setups. Incase you want to trigger it manually, use the command npm run db:create on ToolJet server. :::

Features

ToolJet database allows you to:

Maintain tables of data in a secure database that's only accessible within your ToolJet organization.
Edit, search, filter, sort, and filter data using a spreadsheet-like interface.
Quickly build applications and write queries to interact with the ToolJet Database, just like any other datasource but without any setup.
Export schema from the ToolJet Database to a JSON file.

Accessing ToolJet Database

Once you log-in to your ToolJet account, from the left sidebar of the dashboard you can navigate to ToolJet Database.

The ToolJet Database is available on: ToolJet Cloud, Self-Host, and Enterprise Edition. You can view and manage your database and the data it contains using the Database editor UI.

Database Editor

You can manage the ToolJet Database directly from the Database Editor. ToolJet Database organizes the data into tables that can have different structures. All the tables will be listed lexicographically on the left, click on any of the table to view the table data.

The sidebar on the left can also be collapsed to give more space to the database editor.

Create New Table

For creating a new table in ToolJet Database, click on the Create New Table button on the top left corner of the Database editor.

When the Create New Table button is clicked, a drawer opens up from the right from where you can enter the details of your new table.

For creating a new table, you'll need to:

Enter a Table name
Add Columns (id column with serial data type is automatically created as the primary key of the table)

Supported data types

Data type	Description	Example
serial	serial is used to generate a sequence of integers which are often used as the Primary key of a table. Whenever a new table is created in the ToolJet database, a column id with the serial data type is automatically created as the primary key of the table.	Numbers starting from 1, 2, 3, 4, 5, etc.
varchar	varchar data type is used to store characters of indefinite length	Any string value
int	int is a numeric data type used to store whole numbers, that is, numbers without fractional components.	Numbers ranging from -2147483648 to 2147483647
bigint	bigint is a numeric data type that is used to store whole numbers, that is, numbers without fractional components.	Numbers ranging from -9223372036854775808 to 9223372036854775807
float	float is also a numeric data type that is used to store inexact, variable-precision values.	Any floating-point number, ex: 3.14
boolean	boolean data type can hold true, false, and null values.	`true` or `false`

Search Table

Open the Search bar by clicking on the Search button and search for a table in the ToolJet database by entering the table name.

Rename Table

To rename a table, click on the kebab menu icon on the right of the table name and then select the Rename table option. A drawer will open from the right from where you can edit the table name.

Add new column

To add a new column on a table, either click on the kebab menu icon on the right of the table name and then select the Add new column option or click on the + button present at the end of the column header.

A drawer from the right will open up where you can enter the details for the new column:

Column Name: Enter a unique name for the new column, serving as its key identifier.
Data Type: Choose the appropriate data type for the column from the available options.
Default Value: Specify any default value that should be assigned to the column. Optionally, users can leave this field blank. When a table contains rows and NOT NULL is applied to one of its existing or new columns, specifying a default value becomes compulsory.
NULL/NOT NULL: Use the switch to determine whether the column should allow NULL values or not. By default, the toggle is off, allowing the column to have blank or empty entries. If you turn it on, the column is set to NOT NULL, meaning it can't have blank or empty entries anymore. But, for text columns, even with NOT NULL on, they can still have empty text (like an empty line) but not completely blank entries

You can bulk upload data to the ToolJet database by clicking on the Bulk upload data button on the top of the database editor. On clicking the button, a drawer will open from the right from where you can upload a CSV file. This file is used to upsert records onto the table. If data for id column is missing it will insert new record with the row data else if id is present it will update the corresponding record with the corresponding row data.

From the drawer, users can download the template CSV file in which they can enter the data to be uploaded to the ToolJet database's table or format their CSV file in the same way as the template file.

Once the CSV file is ready, click on the file picker to select the file or drag and drop the file in the file picker. Now, click on the Upload data button to upload the data to the ToolJet database.

The CSV file should not exceed 2MB in size.
