Load data from Oracle table to MS Excel

Hello everyone!

This tutorial is the exact opposite of one of my previous ODI tutorials. Here I will explain how to transfer the data from your Oracle table to a MicrosoftExcel spreadsheet. The process is quite simple and involves a change inknowledge modules and staging area.

Pre-requisites: Oracle 10g Express Edition with *SQLPlus, Oracle Data Integrator 11g (build version 11.1.1.7.0)

Over here I am assuming you have created your own source table in the Oracle database. In this case my table name is karan_employee. I have also created my target Excel sheet(.xlsx) named sample_excel.

Source table

create table karan_employee(EmpId int primary key, EmpName varchar(20), EmpCity varchar(20));

Target Excel sheet

Note: Make sure you have added the ODBC data source and the DSN name for the Excel sheet.

Open ODI Studio and follow the below steps!

Step 1: Create new data server, physical and logical schemas for both Oracle table and excel sheet

Step 2: Create models by reverse engineering table and sheet respectively

creating models

Step 3: Create an interface

Finally, run the interface. Check the status of the operation under theOperator tab. If the operation was successfully completed, you should now see the Excel sheet populated with data from your Oracle table.

ODI KM Adding Order by Option

You can add Order by statement to queries by editing KM.I have edited IKM SQL Control Append to provide Order by. 1) Add an option to KM named USE_ORDER_BY, its type is Checkbox and default value is False. This option determines you want an order by statement at your query. 2)Add second option to KM named ORDER_BY, type is Text. You will get order by values to your query by this option. 3) Editing Insert New Rows detail of KM. Adding below three line code after having clause. That's it! <% if (odiRef.getOption("USE_ORDER_ BY").equals("1")) { %> ORDER BY <%=odiRef.getOption("ORDER_BY" )%> <%} %> If USE_ORDER_BY option is not used, empty value of ORDER_BY option get error. And executions of KM appears as such below; At this execution, I checked the KM to not get errors if ORDER_BY option value is null. There is no prove of ORDER BY I'm glad. Second execution to get Ord...

Creating Yellow Interface in ODI

Hello everyone! In Oracle data integrator (ODI), an interface is an object which populates one datastore, called the target , with data coming from one or more other datastores, known as sources . The fields of the source datastore are linked to those in the target datastore using the concept of Mapping . Temporary interfaces used in ODI are popularly known as Yellow Interfaces . It is because ODI generates a yellow icon at the time of creation of a yellow interface as opposed to the blue icon of a regular interface. The advantage of using a yellow interface is to avoid the creation of Models each time you need to use it in an interface. Since they are temporary, they are not a part of the data model and hence don’t need to be in the Model. So let’s begin and start creating our yellow interface! Pre-requisites : Oracle 10g Express Edition with *SQL Plus, Oracle Data Integrator 11g. Open *SQL Plus and create a new table Sales ...

Synchronous and Asynchronous execution in ODI

In data warehouse designing, an important step is to deciding which step is before/after. Newly added packages and required DW data must be analyzed carefully. Synchronous addings can lengthen ETL duration. Interfaces, procedures without generated scenario cannot be executed in parallel. Only scenario executions can be parallel in ODI. Default scenario execution is synch in ODI. If you want to set a scenario to executed in parallel then you will write “-SYNC_MODE=2″ on command tab or select Synchronous / Asynchronous option Asynchronous in General tab. I have created a package as interfaces executes as; INT_JOBS parallel INT_REGIONS synch INT_REGIONS synch INT_COUNTRIES synch INT_LOCATIONS parallel INT_EMPLOYEES parallel (Interfaces are independent.) Selecting beginning and ending times and durations from repository tables as ODI 11g operator is not calculating these values. It is obvious in ODI 10g operator. SELECT sess_no...
