String Handling in Tmap??????

[ankit7359]

Hi,

i was trying out a scenario of splitting of name into first,middle and last name accordingly... 

as per my testcase... it worked perfectly with "hello world abc!".

but when i try with any other testcast it fails... 

for example :

"Sudhansu Sekhar Dash" or "Amiya Prasad Mishra"

the result i get is 

"har Dash" or "ishra"

the method used in tmap is ->

StringHandling.RIGHT(row1.ename,StringHandling.INDEX(row1.ename," "))... Pls can anyone help on this....

Job_ViewTmap_viewCapturing first_name from emp nameCapturing last name using "hello world abc!"Capturing last name from emp nameend result of all names...but issue with capturing last name.

hi @nthampi,

You should try using String.split() method instead

hi @TRF,

greetings of the day,

i have tried giving split method,... but i see there are some issues... 

i shall share a screenshot of it.. 

for example my testcase is 

"hello world abc!" -> how would the split method work.... i have considered the case where the method takes single and 2 different arguments.. in single argument method.. i have passed the delimiter by which the name must be split. Note: Should i consider String[](String array), if yes how??

on passing the 2 argument method.... String delimiter and integer.. but this as welll.. failed... 

can you pls help.. or suggest something.. 

thanks in advance

This is what your tMap should look like:

Based on this data sample:

Sudhansu Sekhar Dash
Amiya Prasad Mishra
Sudhansu Sekhar
Amiya

This is the result:

hi @TRF,

thanks for your in-detail solution... 

but i have one final query -> as we are using split method.... is it always necessary for me to define an  object and then the respective indexes of 0,1 and so on must be given across the columns

thanks again....

[TRF]

The Object is here to avoid to have as many String.split() as substrings you have to extract.

I used an Object because it's not possible to declare a variable as a String array.

And finally, yes, you must use indices to get each part of the fullname.

Also, if you have a fullname composed of 2 parts and you want to consider this case as firstName and lastName but not middleName, you must have a double space in the middle (for example, "Sudhansu  Dash").

In this case the middleName will contains an empty string, not a null value but it is not difficult to deal with this situation.

Hi,
Could you please confirm if we can create a generic job in talend which performs different operations on different sets of data.
Basically, we want to process multiple source files (having different schema) with different transformations but the overall processing flow in the job is same for all source files. (Eg a simple Job Flow : FileInputDelimited -> TMap -> tFileOutputDelimited).
If we can create such a generic job, then please help on below points :  
1) How to save and pass different schema definition  for different source files via parameter/file
2) How to pass key field via parameter/file
3) How to save and pass different transformations  via parameter/file
