if I were doing it:
update p set te = concat('Ez itt a(z) ',xxxx,' tájtl');
it would work OK, but xxxx is “key” now, so:
update p set te= concat('Ez itt a(z) ',key,' tájtl');
so I cant do that. How to fix it? Renaming that column is not an option
In MySQL, you have to put the column name in backticks ( ` symbols )
