即使通过Spring Boot在架构中指定H2数据库也无法在列中设置默认值

Question

I am trying to create a very simple REST -based API using H2 DB and Spring Boot .

Everything seems to work fine except one part which is the data insertion from import.sql file.

The ACTIVE column in the table does not get populated with data even though the schema specified the default value as Y and NOT NULL (See image below).

src/main/resources/schema.sql

DROP TABLE IF EXISTS COUNTRY;
CREATE TABLE IF NOT EXISTS COUNTRY(
    COUNTRY_ID SERIAL PRIMARY KEY, 
    COUNTRY_NAME VARCHAR(100) NOT NULL, 
    ISO_ALPHA2_CODE VARCHAR(2) NOT NULL, 
    ISO_ALPHA3_CODE VARCHAR(3) NOT NULL, 
    ISO_NUMERICAL_CODE INTEGER NOT NULL, 
    ACTIVE CHAR(1) DEFAULT 'Y' NOT NULL
);

src/main/resources/import.sql

INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Afghanistan','AF','AFG','4');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Aland Islands','AX','ALA','248');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Albania','AL','ALB','8');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Algeria','DZ','DZA','12');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('American Samoa','AS','ASM','16');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Andorra','AD','AND','20');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Angola','AO','AGO','24');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Anguilla','AI','AIA','660');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Antarctica','AQ','ATA','10');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Antigua and Barbuda','AG','ATG','28');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Argentina','AR','ARG','32');
INSERT INTO COUNTRY (COUNTRY_NAME,ISO_ALPHA2_CODE,ISO_ALPHA3_CODE,ISO_NUMERICAL_CODE) VALUES ('Armenia','AM','ARM','51');

I beleive Spring boot is doing ddl-auto=createDrop, does the data stay after the application ends? specify validate in your application.yml instead. 1 thing that i saw in looking up answers is the default was specified after nullability. the guys in the comments are definitely right about the schema though, if it was really NOT NULL h2 would throw error when trying to set column value to null.
ok so it's definitely Spring boot auto config ..

You can set spring.jpa.hibernate.ddl-auto explicitly and the standard Hibernate property values are none, validate, update, create, create-drop. Spring Boot chooses a default value for you based on whether it thinks your database is embedded (default create-drop) or not (default none).

default is create-drop which creates the schema runs the app then drops it. If you plan to create the schema yourself choose none or validate.
