Hierarchical Data Transformation

hi folks,

I've spent several houres to figure out the solution for the following hierarchical data-transformation problem. Without any success!
Is there any best practice pattern in pdi for solving this:

Target-Structure (i.e in DataGrid)

level name
1 A
2 AA
2 AB
3 ABA
3 ABB
3 ABC
1 C
2 CA
3 CAA
3 CAB


to this Destination-Structure:


level1 level2 level3
A AA
A AB ABA
A AB ABB
A B ABC
C CA CAA
C CA CAB

The number of possible levels is static (3).

Thanks in advance for any useful answers.

Loop /Page through query in 100 record chunks?

Hello,

I am querying a table for a list of thousands of ID's which I want to want to store in a variable and then pass in a webservice call in 100 record chunks to get additional information about the records.

I can figure out how to make the webservice and retreive the data but what I dont know how to do is page through the query. Can anyone point me at the right transformation steps I should look at to accomplish this, for example, single threader?

Table Output: Identity Column Value

August 5, 2013, 5:52 am

Hi Team,

I am trying to transfer data from 'SQL server' to 'Sybase' database for a table which has 'identity column' in it.

Since i want the identity column values also to be inserted in the target, i have created a transformation with the following steps:

1. 'Execute SQL script' with 'Set identity inert 'table1' on'.
2. 'Table Input' from Sql server.
3. 'Table Output' to Sybase.
4. 'Execute SQL script' with 'Set identity inert table1 off'.

Also i have made the transaction 'Transformational'.

Is 'Step 4' ( setting identity insert to 'OFF' again) compulsory? Even without Step4 , When i execute the transformation is working fine.
( I am facing problems if i have 'Step 4' sometimes as i get error 'cannot insert values into identity column set to off'.)

Please let me know is this the correct way to insert values into the identity column of a table.?

Thank you.

Naseer.

Page break (Print)

Hi !

Does anyone know how to insert Page Breaks in a Dashboard ?
Because I use the window.print() function in a javascript code to export my dashboard to PDF (it contains table components, so that seems the only way), and sometimes a table is cut in the middle... That does not look good at all !


Thanks

Hi,

I want to check that the namespace of the XML file I want to load is the right one.
Does anybody have a quick sample on that?

I've tried ../../../*[name()='Document@xmlns'] with a loop xPath like /*[name()='Document']/*[name()='Level1']/*[name()='Level2'] but I can't get anything.

Thanks!

Good Morning.

Is there a way to count the number of entries in a Row Result?

I have a sequence of information that I put into a result (Copy Rows to Result). Is there a way to determine the number of individual rows in a result (using JavaScript/Java/Other)?

Thank you for your assistance.

Training algorithm

Hi,

I'm training an algorithm to detect whether a twittermessage is positive or negative. I have a trainingset (arff file) with 400 messages (200 labeled positive and 200 negative). The weird thing is that when I change the order of the messages in the training file, my precision also changes. For example when I first have 200 positve messages and then 200 negative messages I have a precision of 80% but when I have an arff file with first 50 positive, then 50 negative, then 50 positive and then again 50 negative, my precision is 75%. Why does the order of your messages in the trainingfile matter? and which order gives the best precision?

Thnx!

Can't get formula step to work

August 5, 2013, 7:15 am

The set up is for now is as simple as possible. A Data Grid step provides singe row with a single field i and the value 0.
And the formula step just adds another field j with value 1 or changes i to value 1. Can't get anything to work no matter what combination of settings I choose.

formula.jpg

The picture shows as formula "[i]" - of course to get the value 1 I tried the formula - yes - "1" (without quotes). I thought maybe the formula step expects at least one variable - whatever - nothing works.

formula.ktr

What I actually want to do is calculate a date starting from TODAY() - which doesn't work of course either - so I boiled it down to above given arrangement.

Any similar example that works would probably help already.

Please help, I am going crazy!

Hi everyone,

I was brought on board to support a PDI project. I am not the original developer (He has since left the company). I am trying to figure out what version of PDI they have installed in Production. It is on a Linux server. I only have access through command line (putty).

Does anyone know where I can find the version number?

Thanks,

reading a not so fixed text file

hello
i'm having a hard time on reading a sequential file that is partly fixed. i've tried several steps but couldn't figure out how to make this work

My file has a listing of people. Each record has a line with P on it and a variable number of records on each row. I couldn't figure out how to read the P, then read the next x lines (number of lines is variable) and storing it on a row..then reading the next P and the next rows as a new record.

My file is something like:

HEADER
P <--marks the begining of a record
1JOHN DOE <--1 identifies what kind of info comes next, on this case it's name
212309029309<--2 is the idenfier of the info..it could be social security number, for example
319800918 <---same for 3...this time birth date
P
1Ronaldo
319800601 <---this record doenst have the type 2 info
P
and it goes on..

is there a way to do this with pdi? i'm desperate..hahaha

finding association rules for a particular attribute?

Hi,
I would like to find association rules in a Data set using weka, But I would like my algorithm (apriori) to ONLY look for rules that have attribute X in their right side.
let me explain with an example, lets say I have a dataset including attributes A, B and C. assuming that C is the important (or class) attribute, I would like to have only the rules that have C in their right side, like:
A,B => C
B,A => C
B=>C

but not to have rules like:
A,C =>B
C,A =>B
C=>A

how can I set this in explorer? to force algorithm to contain an attribute in the right side of generated rules?

Thank you so much,
Sahar.

New Fields created in Plugin (custom) step does not get through to the next step

Hello , I am fairly new to creating custom components in kettle. I created my own plugin step say ParseLog in which I have a Field1 input coming into this step from say a file and I am doing some custom logic and splitting it into n number of fields. I have created an another plugin step say LoadToOurDB which takes the output of previous step and loads into our proprietary database . So my problem is that I am able to see all the fields created in ParseLog step come to my LoadToOurDB step and also everything comes through properly when I preview but if I throw in a say Output To File step instead of LoadToOurDB and do Get Fields while setting up , I just get the Field1 and none of the other fields that I created in my ParseLog plugin step. This is what I do and I was wondering what is going on ? Thanks for the help in Advance.


public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException {
meta = (MyLogParserStepMeta) smi;
data = (MyLogParserStepData) sdi;


Object[] r = getRow();

if (r == null) // no more input to be expected...
{
setOutputDone();
return false;
}

if (first) {

data.outputRowMeta = new RowMeta();
Enumeration enuKeys = columnMapping.keys();
while (enuKeys.hasMoreElements()) {
String key = (String) enuKeys.nextElement();
RowMetaInterface newField = new RowMeta();
String type = columnTypes.getProperty(key);
ValueMetaInterface newFieldMeta = null;

if (type.equalsIgnoreCase("VARCHAR"))
{
newFieldMeta = new ValueMeta(key, ValueMeta.TYPE_STRING);

}else if (type.contains("INT32"))
{
newFieldMeta = new ValueMeta(key, ValueMeta.TYPE_INTEGER);
}else if (type.equalsIgnoreCase("TIMESTAMP"))
{
newFieldMeta = new ValueMeta(key, ValueMeta.TYPE_DATE);
}else if (type.contains("BOOL"))
{
newFieldMeta = new ValueMeta(key, ValueMeta.TYPE_BOOLEAN);
}else
{
newFieldMeta = new ValueMeta(key, ValueMeta.TYPE_STRING);
}

newField.addValueMeta(newFieldMeta);
data.outputRowMeta.addRowMeta(newField);
}

row = new Object[ data.outputRowMeta.size()];

first = false;
}

if (r[0] != null)
{
String rowStr = r[0].toString();
String columns[] = rowStr.split("\\|"); // its Has lot more processing but I have simplified it for better understanding


for (int i =0;i < columns.length ;i++)
{
row[i] = columns[i];
}

putRow(data.outputRowMeta, row);

}

return true;
