从表中删除内容后，如何在 C# 的内置 SQL 数据库中将自动增量重置为从 1 开始？

Question

How do I reset Auto-Increment to start from 1 in built-in SQL Database of C# after deleting contents from table ?

The problem I am facing is that, when I delete all the contents from the table with the "DELETE" query and again try to insert new data the "Id" will start from 100 whereas I am expecting it to be start from 1. Can anyone help me to solve this issue where the Primary Key ie, "Id" starts from its seed which is "1" ?

Answer 1

you can set a new current identity value for the identity column with the query below

DBCC CHECKIDENT (mytable, RESEED, 0)
