简介:Postgres使用序列实现主键自增基于navcat操作 前置条件:postgres已经安装,数据库已经设置主键,数据类型int8 一、新建序列 create sequence seq_sys_dept increment by 1 minvalue 1 no maxvalue start with 1; 二、ID与序列自增 选择对应id选项,默认值填写下列命令,其中seq_sys_dept为第一步创建时的名称。

下面的命令将创建名为 test_table的表,它的OID是420,该表有两个字段cola和colb , 字段类型分别为int4和text, 然后向该表插入两行: create test_table 420 (cola = int4, colb = text) open test_table insert OID=421 ( 1 "value1" ) insert OID=422 ( 2 null ) close test_table ...
