Tabelle Entry_table hat keine Spalte namens DATE (Code 1) INSERT INTO Entry_table (AMOUNT, NAME, CARET, DATUM, BALANCE, AMOUNT_PAID) WERTE (?,?,?,?,?,?

Question

Ich erhalte diesen Fehler, wenn ich versuche, Daten einzufügen kann mir jemand sagen, was das Problem ist? Tabelle Entry_table hat keine Spalte mit dem Namen DATE (Code 1):, beim Kompilieren: INSERT INTO Entry_table (AMOUNT, NAME, CARET, DATUM, BALANCE, AMOUNT_PAID) VALUES (?,?, ?,?,?,)

Hier ist mein Code:

Answer 1

Ihre Anweisung create table sagt:

db.execSQL("create table " + TABLE_NAME2 + " (ID INTEGER PRIMARY KEY AUTOINCREMENT,NAME TEXT,CARET INTEGER,AMOUNT INTEGER,AMOUNT_PAID INTEGER,BALANCE INTEGER, "+ 
       "COL_DATE TEXT,FOREIGN KEY(ID) REFERENCES Insert_table(ID_NAME))"); 
       ^^^^^^^^ 

daher Ihre Spalte COL_DATE benannt ist, nicht DATE. COL_DATE ist ein besserer Spaltenname als DATE btw, da DATE ein reserviertes Wort für den SQL-Typ "Date" ist.
