Answer Posted / vidya acharya
1. SOURCE QUALIFIER TRANSFORMATION represents the rows that informatica powercenter server reads from RELATIONAL or FLAT FILE SOURCE when it runs the session.
2. When relational or flat file source definition is added to the mapping, informatica server creates the SQ by default. thus, its a default transformation in informatica.
3. Any source(relational/flat file) cannot be read without using SQ as it converts the database specific datatype to informatica native datatype.
4. For relational sources, additional properties can be configured:
- join 2 or more table originating from same source
- source filter.
- number of sorted ports
- select distinct rows
- user defined join
- specify pre-sql and post-sql query
- sql override.
