org.h2.jdbc.JdbcSQLException: Column “Salman” not found;

Question

I have tried to run the following test in my spring application.

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes=App1Application.class)
@Sql(scripts="customerTest.sql")
@DirtiesContext(classMode=ClassMode.AFTER_EACH_TEST_METHOD)

public class customerTest {


    @Autowired 
    customerRepository  customerDB;

    @Test
    public void countRecords(){

        assertThat(customerDB.count(),is(2l));

    }   
}

and in the customerTest.sql file i have:

insert into customer(id,name,lastname) values(1,"name","lastname");

here is my customer class

@Entity
@Data

public class customer {

    @Id
    @GeneratedValue
    int id;

    String name;
    String lastname;
    }

and i use jpa too:

public interface customerRepository  extends JpaRepository<customer,Long>{

}

The problem is, when i run the test i face with the error:

 org.h2.jdbc.JdbcSQLException: Column "Salman" not found; SQL statement:
insert into customer(id,name,lastname) values(1,"name","lastname")

Meanwhile "Salman" is a value and not a column?

Please pay attention, i am using spring-mvc so there is no Database I have only my models ( customer ) made by code.

Answer 1

The behavior of compiler to make such an error is still a question for me, but I managed to handle this error using this single quote '' rather than double quote ""

I use this

insert into customer(id,name,lastname) values(1,'name','Lastname')

rather than

 insert into customer(id,name,lastname) values(1,"name","Lastname")

Answer 2

Try to use '' (single quotes) instead of "" (double quotes). I think it's a problem in H2 library

Answer 3

I know this is bit late for this answer but it still needs an improvement. Do not pass or insert values like this in database, there is always a chances of SQL injection. What you can do is you can use PreparedStatement and then pass a value to your query by using setString() or setInteger() or what ever value you want to pass. So your query will have a better performance and also the security threats are minimum. For eg,

String insert = "INSERT into table_name(id, name,lastname) values (?, ?, ?)"
PreparedStatement insertStatement = conn.prepareStatement(insert);
insertStatement.setInteger(1, id);
insertStatement.setString(2, name);
insertStatement.setString(3, lastname);
insertStatement.executeUpdate();
insertStatement.close();

where conn is the connection made to your database. And do not forget to close the PreparedStatement and connection.

Answer 4

Try to use FULL PATH to your database in project. This problem was solved after relative path was excluded. There is some bug with "~/RELATIVE_PATH" using in last H2 database versions! Bad example: "jdbc:h2:~\\com\\project\\db\\h2\\h2testdb" GOOD EXAMPLE: "jdbc:h2:C:\\Users\\UserName\\IdeaProjects\\projectname\\com.project\\src\\main\\java\\com\\test\\db\\h2\\h2testdb"

Answer 5

You must set the name of the database table field in the entity module (in your case customer.java class) as follows:

@Column(name = "field_name_in_the_table")
String name;

Then in your SQL script file customerTest.sql write the database filed name as follows:

INSERT INTO customer (id, field_name_in_the_table, lastname) values(1,"name","lastname");
