Output:

 Detail
__________  
Samantha(D) 
Julia(A)
Maria(A)
Meera(S)
Ashley(P)

That means output will contain name concatenated with First alphabet of each occupations.

Select concat(Name,'()') from Occupations

This query gives the concatenated brackets ,but I have to add alphabet based on one's profession.What should I do to accomplish that?

Answer 1

For SQL 2012:
select concat (name,'(',substring(occupation,1,1),')') from table

For other versions..
select name +'('+ substring(occupation,1,1)+')' from table

Concat ignores null values,but you may want to be carefull with '+' since whole output will become null in case any of the expression is null,you can use Isnull to avoid that
