在sql数据加载器中加载之前检查数据时出现问题
[英]Issue while checking data before loading in sql data loader
问题描述
I am using the following code excerpt while loading data in Oracle DB using sql loader: 
使用sql loader在Oracle DB中加载数据时，我正在使用以下代码摘录：
"tran_code POSITION(238:239)," +
"frm_acct POSITION(247:265) \"TO_NUMBER(:frm_acct)\" NULLIF :frm_acct='*******************'," +
"to_acct POSITION(269:287)," +
It is giving an error on NULL IF i guess the issue is clear that i want to insert null when the data contains only asterisk otherwise convert to number and insert. 如果我想问题很明显，那就是我想在数据仅包含星号时插入null，否则转换为数字并插入，这将导致NULL错误。
thanx in advance. 提前谢谢。

You can try something like this - 您可以尝试这样的事情-
"decode(:YOUR_COL,'***************',NULL,TO_NUMBER(:YOUR_COL))"
However, I suggest better option in this scenarios is the "external table". 但是，我建议在这种情况下更好的选择是“外部表”。 Here's link for your reference :- http://docs.oracle.com/cd/B19306_01/server.102/b14215/et_concepts.htm 这是供您参考的链接： -http : //docs.oracle.com/cd/B19306_01/server.102/b14215/et_concepts.htm
