H2：多行插入语句出错

Question

I'm using an in-memory H2 database with an initialisation SQL script. The following table is created:

CREATE TABLE GINA_T_WAM_GUESTDOMAIN (
    WFD_C_NAME VARCHAR(12) NOT NULL,
    WFD_C_BASEURI VARCHAR(128) NOT NULL,

    PRIMARY KEY (WFD_C_NAME, WFD_C_BASEURI),
    FOREIGN KEY (WFD_C_NAME) REFERENCES GINA_T_WAM_GUEST(WFG_C_NAME)
);

Now I can insert some rows in that table like this:

INSERT INTO GINA_T_WAM_GUESTDOMAIN(WFD_C_NAME,WFD_C_BASEURI)
    VALUES('DEVINT', 'https://dev.etat-ge.ch');

INSERT INTO GINA_T_WAM_GUESTDOMAIN(WFD_C_NAME,WFD_C_BASEURI)
    VALUES('DEVINT', 'https://devtech.etat-ge.ch');

But when I try to insert both rows in a single statement:

INSERT INTO GINA_T_WAM_GUESTDOMAIN(WFD_C_NAME,WFD_C_BASEURI)
    VALUES('DEVINT', 'https://dev.etat-ge.ch'),
    VALUES('DEVINT', 'https://devtech.etat-ge.ch');

I get the following error message:

Column count does not match

Does anyone knows about this issue? is it at all possible to insert several lines in one statement?

Answer 1

That's how you can insert multiple rows at the same time in a single SQL statement:

VALUES('DEVINT', 'https://dev.etat-ge.ch'),
      ('DEVINT', 'https://devtech.etat-ge.ch');

It's called row value constructor and is a standard since SQL-92.
