These are available in versions 4.0.0 and later, when using databases where Prisma supports them (PostgreSQL, CockroachDB and MongoDB) Lists of static values, such as ( Int) or ( String).Static values that correspond to the field type, such as 5 ( Int), Hello ( String), or false ( Boolean).For example, cuid() and uuid() are provided by Prisma's query engine for all connectors. Represent DEFAULT values in the underlying database (relational databases only) or.The following example includes a scalar list and a list of related attributes either: Note: You cannot combine type modifiers - optional lists are not supported. The type of a field can be modified by appending either of two modifiers: Control the exact native type that Prisma Migrate creates in the database - for example, a String can be or See an enriched schema when you introspect.

See complete list of native database type attributes per scalar type and provider. For example, if you are using the PostgreSQL provider, String fields where the underlying native type is text will not have a type attribute. Prefixed by where db is the name of the datasource block in your schemaįurthermore, during Introspection type attributes are only added to the schema if the underlying native type is not the default type.Specific to the underlying provider - for example, PostgreSQL uses for Boolean whereas MySQL uses Written in PascalCase (for example, VarChar or Text).In the example data model, User, Profile, Post and Category are models.Ī blogging platform can be extended with the following models: Models are represented by model blocks and define a number of fields. Models represent the entities of your application domain. In this case, the database schema is the single source of truth for the models of your application. Generate the data model via introspection: When you have an existing database or prefer migrating your database schema with SQL, you generate the data model by introspecting your database.In this case, the data model is the single source of truth for the models of your application. Write the data model manually and use Prisma Migrate: You can write your data model manually and map it to your database using Prisma Migrate.

There are two ways to define a data model:

In a social media application you probably have models like User, Post, Photo and Message.

In an ecommerce application you probably have models like Customer, Order, Item and Invoice.

It's also interesting that I had to give column aliases in the SELECT statement to make sure the column names match those declared in the CREATE TABLE.Your data model reflects your application domain. The third column f will be added automatically. It's interesting to note that you don't have to declare all three columns in the CREATE TABLE line. I tried this on MySQL 5.7.27, and it worked. Re comment from can do what you describe this way: CREATE TABLE bar (pop INT NOT NULL, name VARCHAR(100))ĪS SELECT 0 AS pop, NULL AS name, f FROM foo Here's a demonstration: CREATE TABLE foo ( f ENUM('abc', 'xyz') ) ĬREATE TABLE bar AS SELECT f AS b FROM foo įinally, I suggest that if your ENUM has many values in it (which I'm guessing is true since you're looking for a solution to avoid typing them), you should probably be using a lookup table instead of the ENUM data type. You can also use CREATE TABLE AS in creative ways to copy a type definition. You could also use the INFORMATION_SCHEMA tables to get the text of the ENUM definition, and then interpolate that into a new CREATE TABLE statement. You can mitigate the work it takes to do this by using copy & paste, or SQL scripts. You'll probably have to enter all the names again. MySQL does not support CREATE DOMAIN or CREATE TYPE as, for example, PostgreSQL does.
