Queries in Informatica

Queries in informatica are useful in many ways. We can use it to identify mappings across repository in which a particular table is being used.We can use it to identify invalid objects in repository. We can use it to identify if any changes were made to objects on a given day.We even use them for deployment purpose this has been explained in earlier article. Please find the link below
http://dwbuddy.blogspot.com/2014/01/labelling-and-creating-queries-in.html

Suppose we know only table name and we want to know how it is populated and in which all mappings it is being used across informatica repository. We can achieve this by creating query in following way

In repository manger go to tools there we will be having queries .Click new and give the parameters as mentioned in the screenshot

Upon executing the query i.e. clicking the blue arrow icon all the mappings along with folder name which has table Employee being used will be displayed.

Click save so that query can be used for future purpose

To find the changes made in repository on current day. Create the query in the following way

Upon executing all the objects will be displayed that has been changed in last 1 day we can change the day value upon our requirement.The objects will be displayed along with user name who has changed the objects.
This will be pretty useful if the informatica version is a standard one.

To find any invalid objects in repository

All invalid objects i.e. mappings ,sessions etc will be displayed upon executing the following query

In the above queries you might have noticed that query type as personal/shared. This property is set while saving query under permissions category. If permissions is set to all then it is shared query so every one can use it or else it is personal i.e. only the owner of the query can edit/execute it.

Hope this article helps in understanding informatica queries

Comparing Objects in Informatica

We might face a scenario where there may be difference between PRODUCTION v/s SIT version of code or any environment or between different folders in same environment. In here we go for comparison of objects we can compare between mappings,sessions,workflows In Designer it would be present under "Mappings" tab we can find "Compare" option. In workflow manger under "Tasks & Workfows" tab we can find "Compare" option for tasks and workflows comparison respectively. However the easiest and probably the best practice would be by doing using Repository Manager.In Repository Manager under "Edit" tab we can find "Compare" option. The advantage of using Repository manager it compares all the objects at one go i.e. workflow,session and mapping. Hence reducing the effort of individually checking the mapping and session separately. Once we select the folder and corresponding workflow we Can click compare for checking out ...

Types of Joins in Oracle/Teradata

In Data warehousing, irrespective of schema (snow flake schema or star schema) we are using, we should join dimension and fact tables to analyze the business. Below are the frequently used joins: Inner join Left outer Join Right outer Join Cross join Inner Join: Inner join will give you the matching rows from both the tables. If the join condition is not matching then zero records will return. We should use ON keyword to give join condition. Example: Table1: ID Name 1 Krishna 2 Anirudh 4 Ashok Table2: ID Location 1 Bangalore 3 Chennai 4 Chennai We can join above two tables using inner join based on key column ID. SELECT T1.ID, T1.Name, T2.Location FROM Table1 T1 INNER JOIN Table2 T2 ON T1.ID = T2.ID If we are using inner join, it will give us matching rows from both the table. Here in this example, we have 2 matching rows i.e. ID 1 and 4. Below will be the result set for the above exa...

Looping using Expression Transformation in Informatica

One of the most common used transformation in Informatica is Expression transformation. In Expression transformation we can perform various operations such as data conversions i.e to_date,to_char, string manipulation such as substr,instr etc. Now coming to one of the widely and prominent task which we perform using Expression transformation is looping a value. Expression transformation has three types of ports i.e. input,variable and output.Only output port values can be propagated to next transformations. So in order to pass values of input and variable ports to next level of transformation these must be assigned to output ports.The order of execution in Expression transformation is top to bottom and first input then variable and finally output ports are processed. let us consider the following scenario The files should be generated with employee name as file name and that particular file should have the details of that respective employee only, if the employee has more t...
