我正在尝试创建使用BigSerial Data类型的Postgres表作为邀请键。一旦我创建了表,表定义已更改为 bigint NOT NULL DEFAULT nextval('transactions.transaction_id_seq'::regclass), 对此。请让我知道为什么会发生这种情况? 预先感谢Somnath 看答案 如前所述 文件,串行不是“真实的”数据类型,而是便利包装器。如果创建...
I'm guessing BIGSERIAL is the same except as SERIAL except uses a bigint to store the value in the table so you would need to change the entity type to match in this case Hope that helps. [Message sent by forum member 'jsl123' (jsl123)] ...

id bigserial PRIMARY KEY, mainid bigint, d4 text, e5 text, CONSTRAINT secondary_fkey FOREIGN KEY(mainid) REFERENCES main(id) ); 我想将stage中的数据同时插入main和secondary,但我不太确定如何通过重用main中生成的bigserial来实现这一点。我正在尝试一个with query,但是我在secondary中得到的行(指数)比...

Should I useinteger(serial) orbigint(bigserial) for my auto-generated primary key? You should always usebigint. True, anintegeroccupies four bytes, while abigintneeds eight. But: If you have a small table, whereintegerwould suffice, the four wasted bytes won't matter much. Also...

My only gripe is that postgres supports manual IDs (using a sequence yourself) and automatic IDs (using SERIAL) but that glassfish code only supports the latter directly - but gets the name of the automatic sequence wrong - which causes the problems, if you let it control the sequences. ...
