Subject Re: [ib-support] SQL ORDER BY problem
Author Quinton Marks
I wouldnt know how to do both in the same select statement.

I would use a Stored Procedure with 2 seperate select statements in it, the one (WHere c1=x and c2=y)
And the other (WHERE c1=x) and only execute the second one if the first returned no data.

Subject: [ib-support] SQL ORDER BY problem

Hi Everyone,

I am having a problem to find an appropriate SQL select statement for
the following scenario.
I have a table (say A) with columns (say c1, c2, etc). What I need
now is a select statement that returns

all rows with c1=x and c2=y
if no such row exists any c1=x

This doesnt seem to be possible, so I am trying to figure out whether
I can select all rows with c1=x, but
* ordered so that rows with c2=y appear on the top *

It seems that
SELECT * from A where c1=x ordered by c2=y
does not work.

Any alternatives?
