Array fields are only supported in PostgreSQL. MySQL and SQLite don't have native array types.

Operators

Operator	Description
`has`	Array contains value
`hasEvery`	Array contains all values
`hasSome`	Array contains any value
`isEmpty`	Array is empty
`equals`	Exact array match

has

Check if array contains a single value:

// Has "featured" tag
where: {
  tags: { has: "featured" },
}

// Has specific role
where: {
  roles: { has: "ADMIN" },
}

hasEvery

Check if array contains ALL specified values:

// Has both "tech" and "tutorial"
where: {
  tags: { hasEvery: ["tech", "tutorial"] },
}

// User has all required permissions
where: {
  permissions: { hasEvery: ["read", "write", "delete"] },
}

hasSome

Check if array contains ANY of the specified values:

// Has "tech" OR "science" OR "programming"
where: {
  tags: { hasSome: ["tech", "science", "programming"] },
}

// User has at least one admin permission
where: {
  permissions: { hasSome: ["admin", "superuser"] },
}

isEmpty

Check if array is empty:

// No tags
where: {
  tags: { isEmpty: true },
}

// Has at least one tag
where: {
  tags: { isEmpty: false },
}

equals

Exact array match (order matters):

// Exactly these tags in this order
where: {
  tags: { equals: ["featured", "top"] },
}

Examples

Tagged Content

async function getPostsByTag(tag: string) {
  return client.post.findMany({
    where: {
      tags: { has: tag },
      published: true,
    },
  });
}

Multiple Tags

async function getPostsWithAllTags(tags: string[]) {
  return client.post.findMany({
    where: {
      tags: { hasEvery: tags },
    },
  });
}

async function getPostsWithAnyTag(tags: string[]) {
  return client.post.findMany({
    where: {
      tags: { hasSome: tags },
    },
  });
}

Permission Check

async function getUsersWithPermission(permission: string) {
  return client.user.findMany({
    where: {
      permissions: { has: permission },
    },
  });
}

async function getUsersWithAllPermissions(permissions: string[]) {
  return client.user.findMany({
    where: {
      permissions: { hasEvery: permissions },
    },
  });
}

Untagged Content

async function getUntaggedPosts() {
  return client.post.findMany({
    where: {
      tags: { isEmpty: true },
    },
  });
}

Role-Based Access

async function getAdminUsers() {
  return client.user.findMany({
    where: {
      roles: { hasSome: ["ADMIN", "SUPERADMIN"] },
    },
  });
}

Updating Arrays

// Add to array
await client.post.update({
  where: { id: "post_123" },
  data: {
    tags: { push: "new-tag" },
  },
});

// Set entire array
await client.post.update({
  where: { id: "post_123" },
  data: {
    tags: { set: ["tag1", "tag2", "tag3"] },
  },
});

Alternative for MySQL/SQLite

Use JSON arrays instead of native arrays:

// Schema
const post = s.model({
  id: s.string().id(),
  tags: s.json().default([]),  // JSON array
});

// Query with JSON operators
where: {
  tags: {
    array_contains: "featured",
  },
}
