Managing Sequential Values with SQL Sequences or Identity Columns
Article Introduction：If you need to simply and automatically assign unique IDs, you will be given priority to using IdentityColumn; if you need to share numbers across tables or flexibly control the generation logic, select Sequence. IdentityColumn is simple to use and is suitable for single table primary key scenarios. It automatically assigns values when inserted, without manual intervention, but has poor flexibility. Sequence provides more powerful functions, such as prefetching values, setting step sizes and recurrent behavior, and supports multiple table sharing numbers. It is suitable for complex business needs, but has a high complexity in use. Selection basis: 1) Only use a single table without controlling details → Identity; 2) Multiple tables share numbers, pre-get values, custom rules → Sequence.
