The name of the fields argument on the @@id attribute can be omitted: Note: Until version 3.0.0, the signature was: When you create a user, you must provide a unique combination of firstName and lastName: To retrieve a user, use the generated composite ID field (firstName_lastName): When creating new User records, you now must provide a unique combination of values for firstName, lastName and isAdmin: When creating new Post records, you now must provide a unique combination of values for authorId (foreign key) and title: Default values can be a static value (4, "hello") or one of the following functions: Default values that cannot yet be represented in the Prisma schema are represented by the dbgenerated() function when you use introspection. Thanks for the info. Making statements based on opinion; back them up with references or personal experience. type modifier, the field will be required on every record of the model. If more strictly date type wanted derived from some databases, prisma should make DBs enable to configure other timezone. Not supported by MongoDB Used to generate an ObjectId for @id fields: The auto() function is not available on relational databases. Defines a data source in the Prisma schema. You can still use, Enums are implemented and enforced at Prisma level in MongoDB, Enum names must start with a letter (they are typically spelled in, start with a letter (they are typically spelled in.

In the following example, the User ID is represented by the id string field that accepts an auto-generated ObjectId: In the following example, the User ID is represented by the id string field that accepts something other than an ObjectId - for example, a unique username: MongoDB does not support @@id What's the difference between ISO 8601 and RFC 3339 Date Formats? You can add unique attributes to your models to be able to uniquely identify individual records of that model. Note that the file must be in the same directory as your schema.prisma file to automatically picked up the Prisma CLI. Currently, scalar lists are therefore only supported when using PostgreSQL or CockroachDB (since MySQL and SQLite don't natively support scalar lists). If that happens, we are more than happy to adopt it and update our APIs. By clicking Sign up for GitHub, you agree to our terms of service and Add @ignore to a field that you want to exclude from the Prisma Client (for example, a field that you do not want Prisma users to update).

When you introspect a relational database, unsupported types are added as Unsupported : The Unsupported attribute allows you to define fields in the Prisma schema for database types that are not yet supported by Prisma. A boy can regenerate, so demons eat him for years. Defines a compound unique constraint for the specified fields. We should give some examples and explain the format that's accepted. 4 bytes signed auto-incrementing integer. Some fields include attributes: See complete list of scalar field types . This is the format used for both storing data and for inserting data. When running a Prisma CLI command that needs the database connection URL (e.g. Accepts a String value in 2.17.0 and later, which allows you to: String values in dbgenerated might not match what the DB returns as the default value, because values such as strings may be explicitly cast (e.g. We are aware of limitations with dates and might be looking into fixing these in the future - so every comment and issue that explains what exactly and why this is limiting will influence our decision making there. What is the format for the PostgreSQL connection string / URL? Note: The leading underscore in a signature means the argument name can be omitted. You can also use dbgenerated() to set the default value for supported types. As an example, take a User table in a PostgreSQL database, with: You can create this with the following SQL command: Introspect your database with the following command run from the root directory of your project: You will get the following Prisma schema: The id, name and isActive columns in the database are mapped respectively to the Int, String and Boolean Prisma types.

You can optionally define a custom index name in the underlying database. Also, on a related note, did a search in the docs for DateTime CRUD ops, and couldnt find anything. I also went through the issue and it seems to me this is not a serialization fault in Prisma as we just call toISOString() in the Date object that we receive which the engines component can parse and send to the database. The following example defines a multi-column unique constraint based on the email field of the User model and the number field of the Address composite type which is used in User.address: This notation can be chained if there is more than one nested composite type: You can define indexes on one or multiple fields of your models via the @@index on a model.

A common approach for naming tables/collections in databases is to use plural form and snake_case notation - for example: comments. To make it easy to get started, Prisma provides a small number of core scalar types that should cover most default use cases. Non-indexed / unsearchable variable length string with optional length described in parenthesis. This is a fairly simple example, but I'd need to do that for every schema model and every date field I'll ever use, right? What kind of number is this?

It makes code simple and have advantages about performance when indexing if it as numerical data. For example: See Prisma's database connector pages for the default type mappings for a given database. If the underlying data type is STRING, you must use one of the following formats: Microsoft SQL Server does not have a specific data type for JSON - however, there are a number of built-in functions for reading and modifying JSON.
