Question

Derby文档syscs_util.syscs_backup_database。

我做了以下琐碎的课程：

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);

    }
}

并且得到了以下指示：Spring JDBC 3.0.4无法理解这种情况。我看不出如何使用位置？为此目的，甚至只是将参数硬编码到调用中（虽然我几乎没有划过那个表面）。

Answer 1

尽管提示添加.withCatalog的错误消息，但解决方法是.withSchema，而不是。
