Removing Trailing Characters

haymarketpaul — Wed, 17 Jun 2015 12:44:57 GMT

I data in a field which is typically in the following pipe delimited format

Text1|||||

Text1|Text2|Text3|||

Text1|Text2||||

I would like to remove all the trailing pipes - however many there are

I was trying something a long the lines of this but it doesn't quite seem to work...

Mid(Field1,1,FindOneOf(Field1,'|',-1)-1)

AS Field1

Any ideas greatly appreciated

Use purgechar function

PurgeChar(s1, s2)

Returns the string s1 less all characters contained in string s2.

Example:

purgechar ( 'a1b2c3','123' ) returns 'abc'

Replace(Field1, '|', ' ')

in your case

purgechar(fieldname,'|') as fieldname

this should give the desired output

I only want to get rid of the trailing pipes at the end - i think those 2 solutions would also affect the genuine pipes in the middle as well

Try like this

"I would like to remove all the trailing pipes "

LOAD Concat(T,'|') as T1 where Len(Trim(T));

LOAD (SubField('Text1|Text2|Text3|||','|')) as T AutoGenerate 1;

Don't know if you still have this problem, but the solution I used in Qlik Sense was this:

replace(trim(replace(Keepchar(concat(distinct SalesOrder&' | '), '1234567890|'), '|', ' ')), ' ', '|')

So, I first replaced the '|' with the space-character. Then I used Trim() to remove the trailing spaces, and then replace to convert the spaces back to '|'. This of course only works if you have no spaces in the data to process.

If you have spaces, you might have to replace first to get them out of the way, and revert them back once your done.

One solution in the Script. Drop the Fields which doesn't have data.

tab1: LOAD * INLINE [ Text1||||| Text1|Text2|Text3||| Text1|Text2|||| ](delimiter is '|', no labels); Set vDropFields=''; FOR i = 1 to NoOfFields('tab1') LET vFieldName = FieldName($(i),'tab1'); LET vFieldValueCount = FieldValueCount('$(vFieldName)'); If $(vFieldValueCount)=1 And FieldValue('$(vFieldName)', 1)='' Then Trace ***Inside; Let vDropFields = '$(vDropFields)'&If('$(vDropFields)'<>'',',')&'$(vFieldName)'; EndIf NEXT i Drop Fields $(vDropFields);

Dropped the Fields.
