  • oracle sequence语句重置方介绍 在开发过程中,可能会用到oracle sequence语句,本文以oracle sequence语句如何重置进行介绍,需要的朋友可以参考下Oracle重置sequence语句1 Sql代码 代码如下: DECLARE n NUMBER(10 ); tsql VARCHAR2(100 ); p_seqName varchar2(20 ); BEGIN p_seqName := ‘SEQ_RUN_ID’; ...
  • Oracle中使用触发器(trigger)和序列(sequence)模拟实现自增列实例 ... Oracle中虽然没有自增列的说法,但却可以通过触发器(trigger)和序列(sequence)来模式实现。 示例: 1、建立表 代码如下:create table user  (       id   number(6) not null,       name   varchar2(30)   not null primary key  )  2、建立序列SEQUENCE 代码如下: create sequence user_seq in
  • Python中关于Sequence切片的下标问题详解 ... 会使用到的语法, 不管是元组, 列表还是字符串, 一般语法就是: sequence[ilow:ihigh:step] # ihigh,step 可为空; 为了简短易懂, 暂时排除step的用法考虑 先来简单示范下用法 sequence = [1,2,3,4,5] sequence [ilow:ihigh] # 从 ... # 从ilow开始直到末尾 sequence [:ihigh] # 从头部开始直到ihigh结束 sequence [:] # 复制整个列表 语法很简洁, 也很容易
