Spring JDBC versus Derby Stored Procedure ...

Question

Derby documents syscs_util.syscs_backup_database.

I made the following trivial class:

public class DerbyMemoryDatabaseDumpDao extends JdbcDaoSupport {
    private SimpleJdbcCall caller;

    @PostConstruct
    public void initialize() {
        caller = new SimpleJdbcCall(getDataSource()).withCatalogName("SYSCS_UTIL")
            .withProcedureName("SYSCS_BACKUP_DATABASE");
    }

    public void dumpDatabase(String whereTo) {
        SqlParameterSource in = new MapSqlParameterSource().addValue("BACKUPDIR", whereTo);
        caller.execute(in);

    }
}

And was rewarded with the following indication that Spring JDBC 3.0.4 is failing to make sense of the situation. I can't see how to just use a positional ? for this purpose, or even to just hard-code the parameter into the call (though I've barely scratched that surface).

Answer 1

In spite of the error message which suggested adding .withCatalog, the solution to this was .withSchema, instead.
