Answer / vanitha
Source Qualifier Transformation basically converts
different data types to Informatica Compatible Data types.
The additional Feature of it to allow the developer to
override the SQL (Only while reading database sources) adds
better design in the map. [instead of having additional
Filters and Sorters].

Source qualifier is the first transformation which reads
data from relation of FF source.

or remove the dupliate data via SQL Query.

Answer / 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.

Answer / ravi kumar
This type of an active transmission. which allows to read the data from relational or flat file.
