Hello Splunker !!

XBY-123-UTB

SVV-123-TBU

I want extract to trim the value according

Condition  :  for XBY-123-UTB I want to trim to XBY only 3 character

                      for SVV-123-TBU I want to trim the string till to 7 character

What I have tried :

Column name is : Employee_number

If(LIKE(Employee_number,"%SVV%"),substr(Employee_number,1,7), LIKE(ubstr(Employee_number,1,3))

 

But this is not working for me. Please help me in this and provide  me other approaches as well.

Your "if" function is wrong. You should use something like this:

if(like(data,"SVV%"), substr(data, 1, 3), substr(data, 1, 7))

I've tested it with the following query:

|  makeresults
| eval data = "XBY-123-UTB,SVV-123-TBU"
| fields - _time
| makemv data delim=","
| mvexpand data
| eval result = if(like(data,"SVV%"), substr(data, 1, 3), substr(data, 1, 7))

What, specifically, does "is not working" mean in this case?

Consider using a case statement, since you have multiple criteria for trimming the field.

| eval Employee_number = case(like(Employee_number,"SVV%"),substr(Employee_number,1,7), 
     like(Employee_number, "XBY%"), substr(Employee_number,1,3),
     1==1, Employee_number)

I believe the like function must be in lower case.  Also, the third argument to the if function must not be a boolean.

| makeresults 
| eval Employee_number="XBY-123-UTB"
| eval value=case(match(Employee_number,"(?i)SVV"),substr(Employee_number,1,7),1==1,substr(Employee_number,1,3))

 

and testing

| makeresults 
| eval Employee_number="SVV-123-TBU"
| eval value=case(match(Employee_number,"(?i)SVV"),substr(Employee_number,1,7),1==1,substr(Employee_number,1,3))
| makeresults

| eval value=case(match(Employee_number,"(?i)SVV"),substr(Employee_number,1,7),1==1,substr(Employee_number,1,3))
