Split one row into multiple rows, keeping no. of columns same

[Anonymous]

Hi,
I have a MySQL table with numeral values in a column (that I expect not to increase beyond a number, 15 in particular case). If this values exceeds a predetermined number, I want it to split it into smaller values (each value being less than 15, based upon a criteria that I can not put up here), and distribute into different rows.
For example, if the rows reads something like
id | name | value
1 | abc | 33
2 | pqr | 12
expected output:
id | name | value
1 | abc | 11
2 | abc | 14
3 | abc | 8
4 | pqr | 12
I read that tMap does something similar this (basically for fixed number of output rows), but don't know if it gives this for dynamic number of rows?
thanks
Gn

Your best approach might be to use tMap or tJavaRow to generate a delimited string of your new values e.g. "11,14,8" and then use tNormalize to split it into multiple rows. You'll have to add the id afterwards.

Hello Gnyani,
You can use the combination of tNormalize & or tExtractDlimitedFields to resolve your problem.
Provided If you can write code that splits your data column to split in comma-seperated values.

Hi manjunath.m,
Here is a component TalendHelpCenter:tNormalize which normalizes the input flow following SQL standard.
