Question

我正在使用Scriptella将数据从一个表复制到另一个表（不同的数据库）上。对于源代码，我使用了Mysql示例数据库Sakila中的表film。

复制数据时，我收到此错误消息。

Exception in thread "main" scriptella.execution.EtlExecutorException: Location: /etl/query[1]/script[1]
JDBC provider exception: Unable to get parameter 4

这是表格中的一行。

'1', 'ACADEMY DINOSAUR', 'A Epic Drama of a Feminist And a Mad Scientist who must Battle a Teacher in The Canadian Rockies', 2006, '1', NULL, '6', '0.99', '86', '20.99', 'PG', 'Deleted Scenes,Behind the Scenes', '2006-02-15 05:03:42'

这两个表的DDL语句。

        </script>
    </query>

</etl>

Java代码

public static void main(String[] args) throws EtlExecutorException {
        ProgressIndicatorBase indicatorBase = new ProgressIndicatorBase() {

            @Override
            protected void show(String label, double progress) {
                System.out.println(label + "--> " + progress);

            }
        };

          EtlExecutor.newExecutor(new File("etl.xml")).execute(indicatorBase);
    }

请告诉我我在哪里做错了，或者有解决方法。

Answer 1

您收到的例外是

Driver exception: java.sql.SQLException: Cannot convert value '2006' from column 4 to TIMESTAMP.

似乎特定的DB行在期望TIMESTAMP类型的列中包含值2006，MySQL的格式似乎是

TIMESTAMP - format: YYYY-MM-DD HH:MI:SS

Answer 2

好吧，我想我知道了。只需在参数周围加上引号

?4 应该看起来像“?4”

在源代码中，日期被转换为字符串。因此，当使用不带引号的字符串日期创建插入时，日期解析会在一年后停止，只剩下一个数字
