Split one row of multiple columns into multiple rows

hey!

i am getting input from api's and want to show in Tlogrow.

but when i split one row values into multiple rows in tjavarow then getting only one last row instead of all 3

my javacode is this

// Input columns

String PARMETADAT_ID = input_row.PARMETADAT_ID;

// Split each column into multiple rows

String[] PARMETADAT_ID_Values = PARMETADAT_ID.split(",");

// Iterate over the arrays and output each combination

for (int i = 0; i < PARMETADAT_ID_Values.length; i++) {

  // Set the PARMETADAT_ID for the current iteration

  row11.PARMETADAT_ID = PARMETADAT_ID_Values[i];

  // Output the row

  System.out.println("Output Row: " + row11.PARMETADAT_ID);

   

  // Emit the row (if you're using an output link)

  output_row = row11;

  // ... (any additional logic or processing)

}

output:

Output Row: 6c4e33bb-a7c8-4d71-8594-868eefeb841f

Output Row: 75b9248a-5228-4e69-a862-c0927d5a66ca

Output Row: 9ed56adf-063d-4438-b205-ad4b3b2b0844

.------------------------------------.

|       tLogRow_3       |

|=----------------------------------=|

|PARMETADAT_ID            |

|=----------------------------------=|

|9ed56adf-063d-4438-b205-ad4b3b2b0844|

'------------------------------------'

row11 is my output link to the tlogrow and PARMETADAT_ID is my column name

my job design is this

Hi

tJavaRow does not iterate each row to next component (tLogRow_3), it only output one row for each input data. You can append the PARMETADAT_ID string on tJavaRow and only use one tnormalize after tJavaRow. eg:

 

String temp_PARMETADAT_ID_string="";

 

// Input columns

String PARMETADAT_ID = input_row.PARMETADAT_ID;

// Split each column into multiple rows

String[] PARMETADAT_ID_Values = PARMETADAT_ID.split(",");

// Iterate over the arrays and output each combination

for (int i = 0; i < PARMETADAT_ID_Values.length; i++) {

  // Set the PARMETADAT_ID for the current iteration

  row11.PARMETADAT_ID = PARMETADAT_ID_Values[i];

  // Output the row

  System.out.println("Output Row: " + row11.PARMETADAT_ID);

if(temp_PARMETADAT_ID_string.equals("")){

temp_PARMETADAT_ID_string=row11.PARMETADAT_ID;

}else{

temp_PARMETADAT_ID_string=temp_PARMETADAT_ID_string+";"+row11.PARMETADAT_ID;

}

   

  // Emit the row (if you're using an output link)

  output_row = temp_PARMETADAT_ID_string;

  // ... (any additional logic or processing)

}

Thanks shong for you response

 

Basically, the issue is I have multiple columns not only PARMETADAT_ID. thats why I am not using tnormalize component.

is there any other way to split one row for multiple columns into multiple rows?

I am stuck in this scenario please guide me if I can handle it in Tjavarow then good otherwise guide me to some other flow

 

textractjsonfield output

 

PARMETADAT_ID PARTEXT PARKEY

["21DSA3DSD,21D323S,23SS3DFF"] ["Region, area, test"] ["US, UK, INDIA"]

 

tMAP output

 

PARMETADAT_ID PARTEXT PARKEY

21DSA3DSD,21D323S,23SS3DFF Region, area, test US, UK, INDIA

 

 

THANKS

what's the output you expect? Do you want to generate three output for each column or only one output for all columns like this:

PARMETADAT_ID;PARTEXT;PARKEY

21DSA3DSD;Region;US

21D323S;area;UK

23SS3DFF;test;INDIA

i want only one output like you said

 

PARMETADAT_ID ;PARTEXT; PARKEY

21DSA3DSD ;Regio; US

21D323S ;area; UK

23SS3DFF ;test; INDIa

 

My current output is this

One row with multiple values of columns

 

PARMETADAT_ID ;PARTEXT; PARKEY

21DSA3DSD,21D323S,23SS3DFF ;Region,area,test; US,UK,IDIA

 

My requirement is this

split values of the column into multiple rows

 

PARMETADAT_ID ;PARTEXT; PARKEY

21DSA3DSD ; Regio ; US

21D323S ; area ; UK

23SS3DFF ; test ; INDIa

You must use tNormalizer to split one column into several rows. In this exemple, the input is the one you specified : 123haskjdjkasd,12321uiasdhjksdahsk,2132jhsahdsjadjkasdhjk

 

069U1000001uCSXIA2.pngThe output is 3 rows. is that what you are looking for ?

 

You need to be more precise when you describe your problem. It's not that clear.

Hello,

 

The solution is the following, given that the number of columns and the number of elements per column is stable : 069U1000001uK1uIAE.pngUsing a tSplit and getting each element with a split() and the corresponding index :

my indexes are dynamic bro its not static .

this solution is for static values of indexes
