Home -> Community -> Mailing Lists -> Oracle-L -> RE: if-then-else in SELECT
You can do something like:
SELECT NAME, CASE WHEN NAME = 'AIMEE GORE' THEN 1 ELSE 0 END EXACT_MATCH
FROM AG_CLIENT
WHERE NAME = 'AIMEE GORE' OR NAME IN ('AIMEE','AIMEE GORE')
ORDER BY 2 DESC
Your calling program can check the value in exact_match. If 1, then no
reason to fetch any more records (unless you expect duplicates), otherwise
fetch all remaining records.
HTH,

Subject: if-then-else in SELECT
Hi,
I would like to retrieve records based on the following if-then-else
criteria.
for eg.
retrieve all empolyee names='AIMEE GORE'
if there is no exact match,
retrieve employee names='AIMEE' or employee_name='GORE'
How can I write the SQL?
DB - 8i
thanks.
