postgresql序列号(SERIAL)类型包括smallserial(smallint,short),serial(int)和bigserial(bigint,long long int),不管是smallserial,serial还是bigserial,其范围都是(1,9223372036854775807),但是序列号类型其实不是真正的类型,当声明一个字段为序列号类型时其实是创建了一个序列,INSERT时如果没有给该字段赋值会默认获取对...
In PostgreSQL, the SERIAL data type is a convenient way to create auto-incrementing integer columns. It is commonly used for primary keys and ensures that each row receives a unique, sequential identifier. Under the hood, SERIAL is a combination of a SEQUENCE and a DEFAULT value. This guide...

自增列是数据库的一个常用功能,PostgreSQL的自增列在10的版本出来前,有两种非常简单的方法来实现: 1、serial类型,自动创建一个序列,同时将列设置为INT,默认值设置为nextval('序列')。 create table test(id serial, info text); postgres=# \d+ testTable"public.test"Column |Type|Collation|Nullable|Default...
在Drizzle 社区搜索后,发现该问题在 PostgreSQL、SQLite 等数据库上也存在,相关 issue 和讨论: [BUG]: error: type "serial" does not exist · Issue #2183 · drizzle-team/drizzle-orm · GitHub (PostgreSQL) [BUG]: sqlite __drizzle_migrations id is of "SERIAL" type, which is not a valid type...
" FOREIGN KEY (event_type_id) references event_types(id) on update restrict );Suggested fix:Update documentation to reflect this difference or change implementation to be more compatible. Funnily enough, AUTO_INCREMENT compatibility is mentioned on the documentation for the serial type in postgresql...
SERIAL in Postgresql is just a shortcut for int pk default nextval('table_name.id_seq'); so you have 2 choices, either switch the table definition of the column to SERIAL which will create the sequence for you or just create the sequence yourself. Either way you need to modify your ...
