问题 I'm processing a /etc/group file from a system. I load it with CSV input step with the delimiter : . It has four fields: group , pwfield , gid , members . The members field is a comma separated list with account names of unspecified count from 0 to infinite. I would like to produce a list of records with three fields: group , gid , account . In the first step I use User Defined Java Class , in the second I use Select values . Example Input: root:x:0: first:x:100:joe,jane,zorro second:x:101

问题 I'm using Pentaho Data Integration (Table Input step) to pull in data from a MySQL server. A couple of fields are of the type 'Timestamp', and Pentaho keeps spewing out errors because of the timestamp being NULL (0000-00-00 00:00:00.000000). I added a zeroDateTimeBehavior=convertToNull to the parameters which should take care of the bad timestamps, but it's converting all of my Timestamp data to NULL. One reason why I think it may be happening is because some of my 'good' data is represented

问题 While a "Select All" feature in a select dropdown component would seem to be a straightforward feature, I've had an incredibly hard time finding a workable solution.

问题 I'm brand new to Pentaho and I'm trying to do the following workflow: read a bunch of lines out of a DB do some transformations POST them to a REST web service in JSON I've got the first two figured out using an input step and the Json Output step. However I have two problems doing the final step: 1) I can't get the JSON formatted how I want. It insists on doing {""=[{...}]} when I just want {...} .

The .prpt and .ktr files are both in the same directory. 回答1: Actually, just realized that the issue could be solved by adding Transformation (KTR) as a resource. In this case, one can use the File-Resources menu selection. In the dialog select the transformation you wish to import

问题 I have a CSV file with currency exchanges EUR-USD. The file was downloaded from the Bank of Canada. I downloaded the CSV with data since Oct 10th, 2013 onwards. There are, nevertheless, gaps in the data, ie. days without the conversion rates. I've been fighting (1st day with Spoon Kettle) to find out a simple (but general) way to fill the gaps, say, with the last non-null value. And the only way I've managed to accomplish this is by chaining 4 "Get previous row fields" and the using the NVL
