    where?: WhereOptions<any>
    withCount?: string[]

    Association aliases to count without loading their rows. Each sets <alias>Count on every returned row.

    const users = await User.findAll({ withCount: ['posts'] });
    users[0].postsCount; // number

    Resolved with one grouped query per association, so the statement count does not grow with the number of parent rows. Prefer this over a full include when you only need the size.

    schema?: string

    Schema to use for the main table

    tableName?: string

    Overrides the FROM target of the query, in place of the model's own table name. Primarily useful together with cte to select from a CTE result set instead of the model's base table

    // Select from the `org_chart` CTE instead of `employees`
    Employee.findAll({ cte: [...], tableName: 'org_chart' })
    searchPath?: string | string[]

    Search path for query resolution (PostgreSQL)

    using?: string

    Connection name to use for this query Allows querying a different database connection

    // Use analytics connection
    User.findAll({
      using: 'analytics'
    });
    include?: IncludeOptions[] | Includeable[]
    order?: Order
    limit?: number

    Number of records to return

    offset?: number

    Number of records to skip

    group?:
        | string
        | string[]
        | [any, string][]
        | { model: ModelStatic<any>; as?: string }[]

    GROUP BY clause - can be a string, array of strings, array of arrays with function expressions, or array of model objects

    group: 'status'
    group: ['status']
    group: ['userId', 'category']
    group: [['status', 'role']] // Array format for mixed columns and expressions
    group: [[prorm.fn('COUNT', 'id'), 'count']] // Function expressions with alias
    group: [{ model: User, as: 'author' }]
    groupType?: "none" | "rollup" | "cube" | "grouping"

    Type of grouping for advanced aggregation features

    • 'rollup': Generates ROLLUP(column, ...) for hierarchical aggregations
    • 'cube': Generates CUBE(column, ...) for multi-dimensional aggregations
    • 'grouping': Uses GROUPING SETS for custom grouping combinations
    • 'none': No special grouping type (default)
    groupType: 'rollup'
    groupType: 'cube'
    groupType: 'grouping'
    groupingSets?: string[][]

    GROUPING SETS - custom grouping combinations for advanced aggregation Each element is an array representing one grouping set

    groupingSets: [['status'], ['region'], []] // Group by status, region, and grand total
    groupingSets: [['a', 'b'], ['a'], []] // Group by (a,b), (a), and grand total
    having?: HavingOptions<any>

    HAVING clause - filter aggregated results Supports all WHERE operators plus aggregation-specific conditions

    having: { count: { [Op.gt]: 5 } }
    having: { count: { [Op.between]: [1, 10] } }
    having: { $or: [{ count: { [Op.lt]: 2 } }, { totalViews: { [Op.gt]: 1000 } }] }
    raw?: boolean
    transaction?: Transaction
    lock?: LockOptions

    Row-level locking options

    • true: FOR UPDATE (equivalent to 'UPDATE')
    • 'UPDATE': FOR UPDATE - prevents other transactions from modifying the rows
    • 'SHARE': FOR SHARE (PostgreSQL) / LOCK IN SHARE MODE (MySQL)
    • 'KEY SHARE': FOR KEY SHARE (PostgreSQL only)
    • { of: Model }: Lock only the specified table (PostgreSQL)
    // Lock all rows with FOR UPDATE
    User.findAll({ lock: 'UPDATE' })

    // Lock with transaction-level FOR UPDATE
    User.findAll({ lock: true, transaction: t })

    // Lock only the User table (PostgreSQL)
    User.findAll({ lock: { of: User } })
    benchmark?: boolean
    logging?: boolean | ((sql: string, time?: number) => void)
    benchmarkMark?: string
    paranoid?: boolean

    When true, includes soft-deleted records in query results. When false or undefined, excludes soft-deleted records (default behavior for paranoid models).

    false
    unionType?: UnionType

    UNION type for combining multiple queries

    'UNION'
    union?: UnionQueryOptions[]

    Array of union queries to combine with the main query

    subQuery?: boolean

    Subquery support - allows using literal SQL in where clauses Usage: { id: { [Op.in]: prorm.literal('(SELECT id FROM users)') } }

    subquery?: boolean

    Whether to use subquery for includes. When false, uses JOIN instead of IN (SELECT) for includes. When true (default), uses subquery IN pattern for includes.

    true

    // Use JOIN instead of IN (SELECT)
    const users = await User.findAll({
      include: [{ model: Post, where: { status: 'published' } }],
      subquery: false
    });

    // Use subquery IN pattern (default)
    const users = await User.findAll({
      include: [{ model: Post, where: { status: 'published' } }],
      subquery: true
    });
    distinct?: boolean

    When true, applies DISTINCT to the query to remove duplicate rows. Useful when using aggregate functions with includes that may cause duplicates.

    undefined

    // Count distinct users with posts
    const count = await User.count({ distinct: true, include: Post })
    cte?: CTEOptions[]

    Common Table Expressions (CTEs) to use in the query Supports both regular WITH and WITH RECURSIVE

    // Simple CTE
    cte: [{ name: 'active_users', query: 'SELECT * FROM users WHERE active = true' }]

    // Recursive CTE for hierarchy
    cte: [{
      name: 'org_chart',
      columns: ['id', 'name', 'manager_id'],
      query: `SELECT id, name, manager_id FROM employees WHERE manager_id IS NULL
              UNION ALL
              SELECT e.id, e.name, e.manager_id FROM employees e
              INNER JOIN org_chart o ON e.manager_id = o.id`,
      recursive: true
    }]
    stream?: boolean

    Enable streaming results for large datasets When true, returns a ReadableStream instead of waiting for all results

    false
    streamBatchSize?: number

    Batch size for streaming results

    1000
    transform?: (record: any) => any

    Transform function to apply to each record during streaming

    streamHighWatermark?: number

    High watermark for the stream (internal buffer size)

    1000
    attributes?: string[]

    Specify attributes to select when reloading from the database. If not provided, all attributes will be selected.

    hooks?: boolean

    Run beforeReload and afterReload hooks (default: true)
