CREATE FUNCTION sqlserver用户定义函数 创建用户定义函数，它是返回值的已保存的 Transact-SQL 例程。用户定义函数不能用于执行一组修改全局数据库状态的操作。与系统函数一样，用户定义函数可以从查询中唤醒调用。也可以像存储过程一样，通过 EXECUTE 语句执行 创建用户定义函数，它是返回值的已保存的 Transact-SQL 例程...
如果 <method_specifier> 中指定的 CLR 函數方法已經有一個指出 RETURNS NULL ON NULL INPUT 的自訂屬性,但 CREATE FUNCTION 陳述式指出 CALLED ON NULL INPUT,則優先使用 CREATE FUNCTION 陳述式。 無法為 CLR 資料表值函式指定 OnNULLCall 屬性。 EXECUTE AS 子句 指定執行使用者定義函數時所在的安全性內容。

SQL Server 2025 (17.x) Preview introduces an iterated hash algorithm, RFC2898, also known as a password-based key derivation function (PBKDF). This algorithm still uses SHA-512 but hashes the password multiple times (100,000 iterations), significantly slowing down brute-force attacks. This cha...
