You can use sequence generator and then in exp trn, use a variable which reads the 1st number the seq generates and
use filter transformation and take only 1st generated row and +10th record.

When I look at many of the workflow last sessions runs in the workflow monitor I see the number of records that are picked by the transformation is different than the number of records that get updated or inserted in the target table.

For example my sql transformation picks 80,742 rows from the source table. but only 29,813 rows get loaded into the target table.

On further analyzing the workflow log file I can see it loaded both insertable records and updatable records:

WRT_8036 Target: W_SALES_ORDER_LINE_F (Instance Name: [W_SALES_ORDER_LINE_F]) WRT_8038 Inserted rows - Requested: 15284
 Applied: 15284 Rejected: 0 Affected: 15284 WRT_8041 Updated rows - Requested: 14529 Applied: 14529 Rejected: 0 Affected: 14529 

WRITER_1_*_1> WRT_8035 Load complete time: Wed Mar 19 04:41:24 2014

I am not able to figure out why would the workflows load lesser records than what source sql gives. and I would really appreciate some help in this matter.

I have Informatica 9 and an Oracle database in my system. Now I want to install a SQL Server database in my system and add this database to Informatica.

Is that possible ?

Purpose: I need to migrate some of the tables from SQL Server to Oracle database using informatica.

Could anyone let me know, after installing SQL Server, how can I add this SQL Server database to informatica for creating mapping?
