What is the efficient way to remove Non Numeric for a field.
Eg: I need to remove the non numeric character in the Field "No"
Input
-----
Code: Select all
ID | No
1|003A23
2|234-456
3| 2333
Output
--------
I dont think I need to specify all the non numeric character in the Convert function to get stripped out.

I think you do, unless you have additional information which you have not shared about the likely non-numeric characters that may appear in the data.

I was asking if I need to use Convert function.
If I need to use that, I need to specify all the list of non numeric character in the list. Which I don't want to.

Tough.
Create a stage variable containing a list of them. Initialize it only; you don't need to re-derive for every row processed.

How about a double convert to avoid identifying/listing all possible non-numeric characters:
Code: Select all
Convert(Convert("0123456789","",link.column),"",link.column)
The inner convert keeps the non-numeric characters and the outer convert removes them.
