** Conditional split: This transformation is used to split the data based on a condition and it is also a Asynchronous transformation

** Here we check the condition for each and every record and move the data as the o/p for first matching condition, record not satisfying any condition will be moved to default group.

Example: Take employee table using sort  t/r eliminate duplicate rows for Sal column and then using conditional split, split the table based on deptno and at destination add another identity column for no of employees for each dept.

**Derived Column: By using this transformation we can add or change existing column data by some expression..

** It is synchronous transformation.

Example: Add another tax column for emp table by writing expression as Sal*0.1,
                Change existing column ename as Upper(ename).

Conditional statement in SSIS: same as ternary operator in C ** <condition>? <true>:<false> Eg: Gender=="M" ? "Male": "Female" Multicast Transformation : This t/r creates multiple copies of i/p data. it is useful because every time we need not to go to source. ** This will improve task performance. Aggregate Transformation : It is used to convert the detailed values into aggregated data by using Aggregate functions like sum,avg,max,min,count etc. ** It is Asynchronous transformation. Example: to the i/p data from source group by deptno and perform aggregate funcs. Conversion in SSIS ; * Conversion is very important because data from flat file, excel comes to transformations in the form of string(varchar) , so we cannot perform required operations so it require to convert data. 1) Directly at source level : ** Select flat file source, right click--> show advanced editor. ** Select i/p & o/p properties tab, ...

Lesson 67: Join two datasets in SSRS by using Lookup function

How to join two datasets in SSRS by using Lookup function First create two datasets each one with a different datasource. Next insert a table in the report body and insert the required columns from the dataset1. Next in order to insert the columns from 2nd dataset, you need to write a look up function where you need to give the matching columns from both the datasets and the required column from dataset and scope as 2 datset Here since we are inserting the columns of dataset1 first, we are writing exp with scope as dataset 2.
