Subject Re: [firebird-support] How to add addition record in sql output
Author Vishal Tiwari
Thank You Mr. DOM, Rajiv Dular Singh Chauhan, Mr. Paul R. Alrick-
Thanks for your valuable help.
I would like to achieve this using only sql staement.
As Mr. DOM has given an example, which matches to the requirement.
But i need to study and work on this example, because depending upon the data in the database it gives the result, some time one record and some time more records as i tried to use "UNION" with different columns with different values.
Mr. DOM, i think very soon i will get back to you as i will be surrounded by some doubts.
As you questioned, "why i need?", coz for calculation, some times i need fixed no. of records and in database some times it may not be available the required no. of records, so using sql if i get required records with some initialised fix values then it help me to get result within time.
Thanks once again to all.
If any other way to acieve this using sql will be highly appreciated.
Have A Nice Day.

SELECT F1, F2, F3,.... etc..../* your real data */
SELECT '', null, 0, ...etc... /* your dummy row, literals matching types 1:1 */

(But why???)
