Answer 1

TO_NUMBER(SUBSTR(AMOUNT,INSTR(AMOUNT,'$')+1,LENGTH(AMOUNT)-1))

or if it's always the first character and you don't have to worry about spaces

TO_NUMBER(SUBSTR(AMOUNT,2,LENGTH(AMOUNT)-1))

Answer 2

Some versions of Informatica do not support TO_NUMBER() . If that is the case with the version you are using, you will need to use one of the following, as appropriate for your use case:

• TO_INTEGER()
• TO_FLOAT()
• TO_DECIMAL()

See the reference of Informatica functions for usage details.

Answer 3

您可以将源列“金额”放入一个表达式元素中，说“ AMOUNT_INPUT”，然后在该表达式中添加一个新项，以使其中的“ AMOUNT_OUTPUT”成为“ TO_NUMBER（AMOUNT_INPUT）”

Answer 4

您还可以使用以下逻辑来获得所需的结果-REPLACESTR（1，AMOUNT，'$'，''）
