given a table
create table mymy(A int(2),B int(2))
is it possible to use a field value as an alias? Something like (not really):
select A as valueOf(B) from mymy.
No. You can’t. The values are not known until the query is run. And even if you could, you’d have a lot of possibly different values in one column. Which one should be used?
The only valid reason I can imagine for such a request is that you have some kind of EAV design and you want to have a Pivot result.
If that’s the case, you could use Dymanic SQL (run a query, get the results, build another query based on those results and run that one.) But this kind of operations is better done at the application side (get the results and format them there, as you prefer).
