How to update a table whose column name contains an ampersand?

Question

Hello,
I am needing to update a column whose column name contains an ampersand, and cannot figure out a way to do this. Option is not there to have the column name changed.
Ex:
UPDATE aircrafts
SET d&f = 1
WHERE aircraft_code = '737';
this returns an error of missing an = sign
I tried:
SET 'd'||'&'||'f' = 1
doesnt work
Any help is greatly appreciated.
Thanks,
Laura

SET DEFINE OFF
will stop interpreting the & sign as starting of a lexical parameter on the client.
Not sure if you have that issue there.
& might also be a not allowed character in normal column names (didn't test).
In that case you might need to put the column name in ".
+example+
{code}
UPDATE aircrafts
SET "d&f" = 1
WHERE aircraft_code = '737';
{code}
Be aware that in this case the column name must be spelled exactly like it was when the table was created.
Included upper/lower case.
{code}
UPDATE aircrafts
SET "D&F" = 1
WHERE aircraft_code = '737';
{code}
