Overview

Columns define the structure and data types of your tables. The Fynd Boltic Database SDK provides comprehensive support for creating, reading, updating, and deleting columns with a wide variety of data types and constraints.

System Columns​

When you create a table, Fynd Boltic automatically adds three system columns:

  • id - Primary key (auto-generated UUID)
  • created_at - Timestamp when record was created
  • updated_at - Timestamp when record was last modified

These columns cannot be deleted or modified and are automatically managed by the system.

Available Operations​

Creating Columns​

  • Create Column - Add single or multiple columns to a table
  • Field Types - Complete reference of all supported data types

Reading Columns​

  • List Columns - Retrieve all columns with filtering and pagination
  • Get Column - Fetch specific column by name or ID

Modifying Columns​

Basic Usage​

import { createClient } from "@boltic/sdk";

const client = createClient("your-api-key");

// Create a text column
await client.columns.create("products", {
    name: "title",
    type: "text",
    is_nullable: false,
    description: "Product title",
});

// List all columns
const { data: columns } = await client.columns.findAll("products");

// Get specific column
const { data: column } = await client.columns.findOne("products", "title");

// Update column
await client.columns.update("products", "title", {
    description: "Updated product title",
});

Supported Field Types​

Fynd Boltic Database supports 14 different field types:

Each field type has specific properties and validation rules. See the Field Types Reference for complete details.

Key Concepts​

Column Properties​

All columns support universal properties:

  • Name - Unique identifier within the table
  • Type - Data type determining storage and validation
  • Nullable - Whether null values are allowed
  • Unique - Enforce uniqueness constraint
  • Indexed - Create database index for performance
  • Default Value - Value for new records

Type-Specific Properties​

Different field types have additional properties:

  • Number: decimals
  • Currency: currency_format, decimals
  • Phone: phone_format
  • Dropdown: selectable_items, multiple_selections
  • Date-time: date_format, time_format
  • Vector types: vector_dimension
  • Encrypted: show_decrypted, is_deterministic

Constraints and Validation​

  • Column names must be alphanumeric
  • Type conversions have compatibility rules
