Answer / misra
Select a.*,b.*,'update' as type
from a,b where a.1=b.1 and a.2=b.2
union
Select a.*,b.*,'insert' as type
from a,b where a.1<>b.1 or a.2<>b.2
Basically its like scd1,with table A as source and table B as target.
Based on "type" column you can write insert/update statement in stored procedure at db level or keep update strategy in informatica level.

Answer / sri
Write Tablename.columnname in SQL query. In your case,
for selecting all data from table a column 2,the query is:
select * from a.2
So in this way operation of data can be made by using
required SQL operators.
