Mit:
select name, id
from "TEST"
where id :2
AND name :1
order by id desc
Ich ORA: 00904 "TEST"."NAME": invalid identifier Störung erhalten aber der wierd Teil ist, dass ich meine Test-Tabelle überprüft habe und es nicht NAME-Feld hat, aber es Namensfeld hat, habe ich auch überprüfte alle Referenzen, die aus der Tabelle gemacht und alle anderen Einschränkungen aber immer noch gibt es mir gleiche Fehler. Ich weiß nicht, warum, ist es eine Möglichkeit, wo ich alle Spalten der Datenbank für NAMEN Spaltennamen oder anderen debuggind Ansatz überprüfen würde sehr willkommen zu empfehlen.
DESC TEST; Name Null Typ
id NOT NULL NUMBER (11)
Name VARCHAR2 (29)
2 Zeilen ausgewählt
EDIT
DESC TEST
Name Null Type
------------------------------ -------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
ID NOT NULL NUMBER(11)
NAME VARCHAR2(29)
2 rows selected

Lösung
SELECT *
FROM ALL_TAB_COLS
WHERE UPPER(COLUMN_NAME) = 'NAME';
zeigt Ihnen alle Spalten Rufname
EDIT:
Basierend auf Ihren Kommentar, nicht fehlen Sie die Operatoren in Ihrer WHERE-Klausel? ie =
select name, id
from "TEST"
where id :2 -- Surely you mean: id = :2
AND name :1 -- Surely you mean: name = :2
order by id desc
EDIT 2:
Auf der Basis der SQL * Plus-Ausgang, es sieht aus wie Sie die Tabelle mit Kleinspaltennamen erstellt haben. Während dies möglich und gültig ist, dann ist es in der Regel nur harte Arbeit. Ich würde die Spalten mit Großbuchstaben Namen neu erstellen. (Als Alex sagte)
EDIT 3:
Ich denke, ...
SELECT "id", "name"
FROM TEST
WHERE "id" = :1
AND "name" = :2
ORDER BY "id" desc;
sollte funktionieren
Andere Tipps
Es ist eine gute Idee nicht zu Surround-Spalte und Tabellennamen mit doppelten Anführungszeichen, wenn Sie wissen, was Sie tun, und zuversichtlich, was Sie brauchen den.
In Oracle Datenbank-Objektnamen (einschließlich Tabelle und Spalten) sind nicht zwischen Groß- und Klein angenommen Groß- es sei denn, Sie sind sie in doppelte Anführungszeichen.
Z. B, wenn eine Tabelle als TEST erstellt, kann es als test, Test oder TesT oder "TEST" bezeichnet werden.
Aber wenn es als "Test" erstellt wird, werden Sie nur in der Lage sein, um es als "Test" zu beziehen (in Anführungszeichen). Alle anderen Möglichkeiten „invalid identifier“ Fehler führen wird.
