创建序列后,您可以在 SQL 语句中使用CURRVAL伪列返回序列当前值或使用NEXTVAL伪列返回递增的新值。详细信息,请参见序列伪列。 语法 CREATESEQUENCE[schema.]sequence_name {STARTWITHint_value|[INCREMENTBYint_value]|[MINVALUE int_value|NOMINVALUE]|[MAXVALUE in
有关同时使用CREATE SEQUENCE和NEXT VALUE FOR函数的信息,请参阅序列号。 Transact-SQL 语法约定 语法 syntaxsql CREATESEQUENCE[schema_name. ]sequence_name[AS[built_in_integer_type| user-defined_integer_type] ] [STARTWITH<constant>] [INCREMENTBY<constant>] [ {MINVALUE[<constant>] } | {NOMINVALUE...
向当前数据库里增加一个新的序列。序列的Owner为创建此序列的用户。SEQUENCE是一个存放等差数列的特殊表,该表受DBMS控制。这个表没有实际意义,通常用于为行或者表生成唯一的标识符。如果给出一个模式名,则该序列就在给定的模式中创建,否则会在当前模式中创建。序列名必
然后在传入参数让数据库自动替换 SQL 中占位符并执行,在这个过程中,由于预编译好的 SQL 模板本身语法已经定死,因此后续所有参数都会被视为不可执行的非 SQL 片段被转义,因此能够防止 SQL 注入。

If the Database Engine is stopped after you use 22 numbers, the next intended sequence number in memory (23) is written to the system tables, replacing the previously stored number. After SQL Server restarts and a sequence number is needed, the starting number is read from the system tables...
