Return single string

Sat, 04 May 2013 04:46:30 GMT

Hi all,

I have a Customer field, which contains a proper name, for example 'Sony', which has a duplicate, yet different name in the same field, example

'Sony 123a'. I'd like to strip out the 123a and just return the 'Sony', or at least the first record.

Is there any function that could remove or delete the remaining characters after 'Sony'

Thank you

Hi,

Try this syntax it will give you output as you want.

=subfield(PurgeChar('Sony 123a',chr(39)),' ')

There are lots of ways that probably all won't work.

left(Customer,4) will return 'Sony'. But this always picks the first 4 characters

If(left(Customer,4)='Sony','Sony',Customer) will only change Customers that start with Sony to 'Sony'. But it will leave other (duplicate) Customers alone.

subfield(Customer,' ',1) as Customer will return the string before the first space. If you have Customers with a space in their regular name this won't work.

left(Customer,index(Customer,' ',-1)-1) wil return everything before the last space.

If all that doesn't work you can try using wildcard mapping. But for that you have to identify the duplicates anyway.

Maybe you need to buy a data cleansing tool. Such tools are created to do things like this.
