SQL putting text in query output

Description

Sometimes, it is required to get an organized output from a SELECT QUERY. For that, it is better to include some user defined columns from the outside at runtime. These columns are valid only for this output. These included columns will appear as a column head and also as the contents for that column.

Example:

Sample table: agents


To get a formatted output with user defined column( % ) along with the 'agents' table with the following condition -

1. commission must be more than .14,

the following SQL statement can be used:

SQL Code:

SELECT agent_code,agent_name,
working_area,'  %  ',commission
FROM agents
WHERE commission>0.14;

Output:

AGENT_CODE AGENT_NAME         WORKING_AREA                        '%'   COMMISSION
---------- ----------------------------------------------------- ----- ----------
A007       Ramasundar         Bangalore                             %          .15
A011       Ravi Kumar         Bangalore                             %          .15
A006       McDen              London                                %          .15
A004       Ivan               Torento                               %          .15

SQL putting text in query with group by and order by

To get a formatted output with user defined columns ('For','No.of Agent','Agent(s)','in' and '%' ) along with the 'agents' table with following condition -

1. number of agents for each 'working_area' must be less than 3,

the SQL statement can be used:

SQL Code:

SELECT 'For  ',count(agent_name)as "No.of Agent",
'Agent(s)','   in  ',
working_area,avg(commission),'  %  '
FROM AGENTS
having count(agent_name)<3
GROUP BY working_area
ORDER BY working_area DESC

Output:

'FOR' No.of Agent 'AGENT(S 'IN'    WORKING_AREA                        AVG(COMMISSION) '%'
----- ----------- -------- ------- ----------------------------------- --------------- -----
For             1 Agent(s)    in   Torento                                         .15   %
For             1 Agent(s)    in   San Jose                                        .12   %
For             1 Agent(s)    in   New York                                        .12   %
For             1 Agent(s)    in   Mumbai                                          .11   %
For             2 Agent(s)    in   London                                          .14   %
For             1 Agent(s)    in   Hampshair                                       .11   %
For             1 Agent(s)    in   Chennai                                         .14   %
For             1 Agent(s)    in   Brisban                                         .13   %
