Oracle 12c中,可以使用序列的NEXTVAL and CURRVAL的值作为默认值,来实现列自增! 一.使用序列的NEXTVAL and CURRVAL的值作为默认值 创建序列 CREATE SEQUENCE t1_seq; 建表 CREATE TABLE t1 ( id NUMBER DEFAULT t1_seq.NEXTVAL, description ) ); 插入数据 INSERT INTO t1 (description) VALUES ('DESCRIPTION only')…

Oracle Schema Objects 序列的作用 许多的数据库之中都会为用户提供一种自动增长列的操作,例如:在微软的Access数据库之中就提供了一种自动编号的增长列(ID列).在oracle数据库中没有自动增长列. 序列(Sequence)可以自动的按照即定的规则实现数据的编号操作. 序列的创建语法 CREATE SEQUENCE 序列名称 [ INCREMENT BY 步长 ] [ START WITH 开始值 ] [ MAXVALUE 最大值 | NOMAXVALUE ] [ MIN…

项目中,用到一个序列作单号,框架用的是ssh,在dao层去拿的时候,运行时报错为dual is not mapped,[select *.nextval nextvalue from dual] 后来检查发现,获取方式不对,于是改成下面这样,就可以正常获取了 //获取seq的最后一个值 public String findSeq(){ try { String sql = "select PATIENT_SEQ.nextval nextvalue from dual"; Integer…
