Question

我有一个控制文件，该文件将文本加载到oracle中，但是我试图剥离电话号码示例1-469-428-5920到469-428-5920的前3位数字，请参见下面的控制文件。语法应该是什么？

我在下面始终遇到错误，请帮助

谢谢

Answer 1

您还没有说出遇到的错误，但是在case表达式中应该使用双引号（大写或其他形式）。代替：

PHONE "CASE WHEN SUBSTR(:PHONE,1,2) = '1-'  THEN ‘SUBSTR(:PHONE,3)’  ELSE ‘:PHONE’ END",

使用：

PHONE "CASE WHEN SUBSTR(:PHONE,1,2) = '1-' THEN SUBSTR(:PHONE,3) ELSE :PHONE END",

Answer 2

您也可以保留最后12个：

PHONE "SUBSTR(:PHONE, -12, 12)",

在SQL LOADER控制文件中使用案例陈述
