从 Coldfusion 到 Oracle 的数据插入问题

Question

我正在读取一个文本文件，并创建了一个如下字符串以将数据插入数据库 (Oracle 11g)。

INSERT ALL
INTO INDEX_DATA (DATETIME, COMMODITY, IDX, IDX_VALUE, VCDATE) VALUES ('15-May-2014', 'FN1 Comdty', 'PX_LA', 44.75, SYSDATE)
INTO INDEX_DATA (DATETIME, COMMODITY, IDX, IDX_VALUE, VCDATE) VALUES ('15-May-2014', 'FN1 Comdty', 'PX_H', 45.1, SYSDATE)
INTO INDEX_DATA (DATETIME, COMMODITY, IDX, IDX_VALUE, VCDATE) VALUES ('15-May-2014', 'FN1 Comdty', 'PX_L', 44.47, SYSDATE)
and so on ...7000 rows
select * from dual

在一次插入上述查询时，coldfusion 页面超时。该查询适用于 100 条记录。

我真的不确定这是 Oracle 还是 Coldfusion 限制，因为 Toad 也没有响应相同的查询。

如果是冷融合问题，请告知是否有另一种插入数据的方法，而不是为每个插入语句访问数据库。

编辑 1：如果不存在其他解决方案，我可以使用标志并每隔 n 行插入一次。

我会推荐 2 项操作。首先设置请求超时以覆盖您的默认设置。其次，将您的插入语句加载到一个数组中，循环它们，并定期提交。这是一个演示该行为的简单示例。预期的结果是它会在第 12 条记录出现错误之前将 10 个字母插入 tmp 表。前 10 个将被提交。
