wheels db create

Create a new database based on your datasource configuration.

Synopsis

wheels db create [--datasource=<name>] [--environment=<env>] [--database=<dbname>] [--force]

Description

The wheels db create command creates a new database using the connection information from your configured datasource. The datasource must already exist in your CFML server configuration - this command creates the database itself, not the datasource.

Options

datasource=

Specify which datasource to use. If not provided, uses the default datasource from your Wheels configuration.

wheels db create --datasource=myapp_dev

--environment=

Specify the environment to use. Defaults to the current environment (development if not set).

wheels db create --environment=testing

--database=

Specify the database name to create. Defaults to "wheels-dev" if not provided and not found in datasource configuration.

wheels db create --database=myapp_production

--force

Drop the existing database if it already exists and recreate it. Without this flag, the command will error if the database already exists.

wheels db create --force

Examples

Basic Usage

Create database using default datasource:

wheels db create

Specific Datasource

Create database for development:

wheels db create datasource=myapp_dev

Create database for testing:

wheels db create datasource=myapp_test --environment=testing

Custom Database Name

Create database with specific name:

wheels db create --database=myapp_v2

Force Recreation

Drop existing database and recreate:

wheels db create --force

Database-Specific Behavior

MySQL/MariaDB

• Creates database with UTF8MB4 character set

• Uses utf8mb4_unicode_ci collation

• Connects without specifying a database initially

• Supports MySQL 5.x, MySQL 8.0+, and MariaDB drivers

PostgreSQL

• Creates database with UTF8 encoding

• Uses en_US.UTF-8 locale settings

• Terminates active connections before dropping (when using --force)

• Connects to postgres system database

SQL Server

• Creates database with default settings

• Connects to master system database

• Supports Microsoft SQL Server JDBC driver

H2

• Displays message that H2 databases are created automatically

• No action needed - database file is created on first connection

Output Format

The command provides real-time, formatted output showing each step:

Prerequisites

1. Datasource Configuration: The datasource must be configured in /config/app.cfm

2. Database Privileges: The database user must have CREATE DATABASE privileges

3. Network Access: The database server must be accessible

4. JDBC Drivers: Appropriate JDBC drivers must be available in the classpath

Error Messages

"No datasource configured"

No datasource was specified and none could be found in your Wheels configuration. Use the datasource= parameter or set dataSourceName in settings.

"Datasource not found"

The specified datasource doesn't exist in your server configuration. Create it in your /config/app.cfm first.

"Database already exists"

The database already exists. Use --force flag to drop and recreate it:

wheels db create --force

"Access denied"

The database user doesn't have permission to create databases. Grant CREATE privileges to the user.

"Connection failed"

Common causes:

1. Database server is not running

2. Wrong server/port configuration

3. Invalid credentials

4. Network/firewall issues

5. For PostgreSQL: pg_hba.conf authentication issues

Configuration Detection

The command automatically detects datasource configuration from:

1. Environment-specific settings: /config/[environment]/settings.cfm

2. General settings: /config/settings.cfm

3. Datasource definitions: /config/app.cfm

It extracts:

• Database driver type

• Connection string details

• Host and port information

• Username and password

• Database name (if specified in connection string)
