我的表设置如下:
CREATE TABLE "CAMPAIGNS"
( "campaignId" INT PRIMARY KEY GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1),
"campaignName" VARCHAR(200),
"campaignLocation" VARCHAR(200),
"campaignManager" VARCHAR(200)
);
我的INSERT语句应该如何,所以我可以确保campaignId列自动递增,然后我选择将进入表中的其余值?

只需确保campaignId INT Auto_Increment
,然后您就不需要像这样在查询中添加campaignId
:
String query = "INSERT INTO CAMPAIGNS (campaignName, campaignLocation, campaignManager)
VALUES (?, ?, ?)";

INSERT INTO CAMPAIGNS (campaignName, CampaignLocation, CampaignManager)
VALUES ('Test','Sofia','Emil')

有时这会因数据库而异。但是将其删除或使用null通常都可以正常工作。
insert into CAMPAIGNS(campaignId, campaignName, campaignLocation, campaignManager)
values (null, 'My Campaign', 'Australia','Bob');

PreparedStatement preparedStatement =
connect.prepareStatement("INSERT into CAMPAIGNS (campaignName, campaignLocation,campaignManager) VALUES (?,?,?)");
preparedStatement.setString(1, "campaignName");
preparedStatement.setString(2, "campaignLocation");
preparedStatement.setString(3, "campaignManager");

根本没有在插入
中提及insert into CAMPAIGNS ( campaignName, campaignLocation, campaignManager)
values ( 'campaignName_value', 'campaignLocation_value', 'campaignManager_value')
mysql完成剩下的工作
PS没有无用的双引号
