ordersid

ordersid is a field name used in database schemas and application data models to denote the unique identifier of an order. It is commonly implemented as a primary key in an orders table and is used to retrieve, join, and reference a specific order across the system.

Variants and data types: The actual data type depends on the system. It may be a numeric type such as BIGINT, or a string type for alphanumeric identifiers (for example UUIDs or custom codes). Some implementations use a human-readable, sequential order number as the public-facing ID while using a separate internal surrogate key for database joins.

Generation and usage: Order IDs are typically generated at the moment the order is created—by the database (auto-increment or sequence), by the application, or by a UUID generator. In relational databases, ordersid serves as a target for foreign keys in related tables (order_items, shipping, payments) and is also used in API endpoints and reports. It should be indexed to improve lookup performance.

Security and design considerations: Exposing predictable, sequential IDs in public APIs can expose information about volume or timing; many designs employ opaque IDs or hashed representations for external clients while keeping stable internal keys. Consistency in naming, length limits, and collision handling are common concerns.

Example: SQL: CREATE TABLE orders (ordersid BIGINT PRIMARY KEY, customerid INT, orderdate DATE); REST example: GET /orders/{ordersid}.
