    public EmployeeModelRead() {
        super();
    }

}

schema.sql

drop table if exists employee_model_read;

create table EMPLOYEE_MODEL_READ(
  ID BIGINT AUTO_INCREMENT PRIMARY KEY,
  AGE INTEGER(10),
  DOJ VARCHAR(255),
  NAME VARCHAR(255),
  ROLE VARCHAR(255)
);

data.sql

insert into employee_model_read(AGE,DOJ,NAME,ROLE) values (23,'25-09-2020','RAM','Front End Developer');

application.properties

spring.datasource.url=jdbc:h2:mem:batchjob
spring.h2.console.enabled=true
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.batch.job.enabled=false

Data of data.sql file is not getting picked in H2-Database. H2-Database is working fine for the rest other cases. I am using JPA for other DB-related operations. If you want some other files then please tell me so that I can upload it. Please help me to know way this is not working.

Answer 1

After adding this line to my application.properties file the code worked.

spring.jpa.hibernate.ddl-auto= update

Answer 2

I don't know exactly all context. Why don't you set value of ddl-auto config in application.yml. Like below. In my case, it's working.

Note that If you set ddl-auto is validate, you have to match between columns of schema.sql and fields of entity.

spirng: 
  jpa:
    hibernate:
      ddl-auto: validate

Spring documents says that In a JPA-based app, you can choose to let Hibernate create the schema or use schema.sql, but you cannot do both. Make sure to disable spring.jpa.hibernate.ddl-auto if you use schema.sql. In a JPA-based app, you can choose to let Hibernate create the schema or use schema.sql, but you cannot do both.
