Introduction

load.ts is a CLI tool that allows you to

• Load schemas from file system to a database
• Provide custom template to produce any command line operations

Note: Folder strucutre read by load.ts is not configurable as of today. It should be like

<database-server>/<database-name>/schema.sql

There can be multiple databases (database-name) inside a database-server folder. database-schema-examples repo follows this structure.

CLI Arguments Reference

Arg	Required	Description
--folder	true	Load a folder containing database schemas (making them available in templates) assuming the following structure. <dbname>/schema.sql. This is similar to database-schema-examples repo
--db	true	Connection string of the database URL that will be parsed and made available as template args.
--subfolders	false	Comma separated, load selective folders from --folder
--template	false	Template to produce output. See Template Variables below.
--data	false	Also include data.sql (defaults to false, i.e. load.ts only picks schema.sql)

Template Variables

All examples are based on this connection string: sqlserver://localhost:1433;database=test;user=root;password=prisma;trustServerCertificate=true;encrypt=DANGER_PLAINTEXT

In all the examples below,

• Respective database is derived from the connection string provided in --db argument.
• Folder structure is assumed to be similar to database-schema-examples https://github.com/prisma/database-schema-examples/tree/main/mssql
