Hi.
SELECT OKYTNO, "kullanici_ismi"
FROM kullanicilar;
This is the way it works via dbeaver. However, Lazarus says he could not find the column again.
SELECT OKYTNO, "KULLANICI_ISMI"
FROM kullanicilar;
In this way, neither dbeaver nor over lazarus does not work. The double quotes character (") provides upper case separation.
select kullanici_ismi as isimisimisimis, kullanici_ismi as is_im
FROM kullanicilar;
That's how it not works.
select kullanici_ismi as is_im
FROM kullanicilar;
That's how it works.
