org.h2.jdbc.JdbcSQLException：未知数据类型：“DATEADD”； SQL 声明

Question

I'm using h2 to inject the db during run time and testing, everything was working fine until I started trying to make the date field current, not hard-coded. I thought it was related to the jdbc version I've and updated spring jdbc library to be the latest, but that didn't solve the problem.

This is the code I'm using to inject the data both on run-time and testing:

This code runs during run-time, and it works perfectly before I tried to make the date current.

        ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
        resourceDatabasePopulator.addScript(new ClassPathResource("schema.sql"));
        resourceDatabasePopulator.addScript(new ClassPathResource("data.sql"));
        DatabasePopulatorUtils.execute(resourceDatabasePopulator, dataSource); // This is what the DataSourceInitializer does.

For testing purpose, I'm using this code, as I mentioned, it was working perfectly before I tried to make the date current.

        DataSource dataSource = new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2)
                .addScript("classpath:schema.sql")
                .addScript("classpath:data.sql")
                .build();

data.sql file

INSERT INTO  TABLE_X (
  dayxx,
  xxx
) VALUES
(CONVERT(char(50), DATEADD('DAY', -1,CURRENT_DATE()),126),'xxx')

Exception

As reported in the docs , Convert function looks like this:

CONVERT ( value, dataType )

Converts a value to another data type.

Example:

CONVERT(NAME, INT)

Since you're passing

CONVERT(char(50), DATEADD('DAY', -1,CURRENT_DATE()),126)

The error states that DATEADD isn't a valid data type, since it's the value, not the type, so try using the right syntax.
