Problem with the StringHandling in a Tmap

[Anonymous]

Hello,

I have a little problem with your component "Tmap", I can not make "StringHandling.SUBSTR ()".

Here is my mistake when I do an execution.

Job schema:

The inside of my Tmap:

Inside my file (In component: "tFileInputDelimited_1"):

My goal at the end of my job is to have on several fields this sentence (that is to say arrived at 52 characters I pass to the next field)
I have for example the line (which I would like to divide into several fields) that is to say:

Example:
"I eat apples."

I would like to have on several fields this sentence (that is to say arrived at 52 characters I pass to the other following field)

Example:

FIELD_1|FIELD_2|FIELD_3
I eat       |apples.  |


I'm a little stuck because I use Talend methods, I can not do it.
Could you help me ?

PS: Sorry for my English, I do not have the top level.

Bonjour ,

il n'y a pas method SUBSTR dans routine StringHandling.

Au lieu de , Vous pouvez utilise  row1.command_commantier.SUBSTR( .....)

If you want to get a particular range, you can go with substring. I am not sure in your case you would like to separate each word individually. To do so, split() method would help you

Ex:

"I  am a talend developer"

Using substring():

row1.substring(8,14) --> O/P - talend

using split():

"I am a talend developer"

row1.split(" ")[0]- I

row1.split(" ")[1] -am 

row1.split(" ")[2] - a

And your method does not work.

Thank you in advance.

Hello avinashbasetty,

I used the method: row6.commande_commentaire.substring (53,104)

This is not a long length (This product is not a long length)

Here is the error he sends me:

Thank you in advance for your answers and help.

Si vous voulez diviser la column en taille 52 , 

(StringHandling.LEN(row1.command_commantier) > 0  ) ? row1.command_commantier.split("(?<=\\G.{52})")[0]  : null

(StringHandling.LEN(row1.command_commantier) > 52 ) ? row1.command_commantier.split("(?<=\\G.{52})")[1]  : null

(StringHandling.LEN(row1.command_commantier) > 104 ) ? row1.command_commantier.split("(?<=\\G.{52})")[2] : null
