Question

嘿，当我试图插入mysql数据库时..然后我收到错误：

E/SQLiteDatabase: Error inserting userVorname=test userAnrede=Herr userPw=test userPraxisAdresszusatz= userEmail=test userTel=016722435 userPraxisPlz= userPraxisName= userPraxisTel= userPraxisStadt= userName=test userPraxisAdresse= userTitel=
              android.database.sqlite.SQLiteException: table UserDatabase has no column named userName (code 1): , while compiling: INSERT INTO UserDatabase(userVorname,userAnrede,userPw,userPraxisAdresszusatz,userEmail,userTel,userPraxisPlz,userPraxisName,userPraxisTel,userPraxisStadt,userName,userPraxisAdresse,userTitel) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?)

我知道编译器说没有名为userName的列，但在我的经理中我设置了它。我发现没有丢失的逗号或类似的东西..我希望你们能帮助我......

public class UserDatenbankManager extends SQLiteOpenHelper {
    private static final String DB_NAME = "UserDatabase";
    private static final int DB_VERSION = 1;
    private static final int COL0 = 0;
    private static final String COL1 = "userName";

    pAdrZs,
                           String pw)
    {
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues contentValues = new ContentValues();
        //contentValues.put(COL0, new Integer());
        contentValues.put(COL1, name);
        contentValues.put(COL2, vorname);
        contentValues.put(COL3, anrede);
        contentValues.put(COL4, titel);
        contentValues.put(COL5, tel);

        contentValues.put(COL11, pTel);
        contentValues.put(COL12, pAdrZs);
        contentValues.put(COL13, pw);
        db.insert(DB_NAME, null, contentValues);

请使用以下sql脚本创建表。我认为你的表是由于你的sql create query中的错误而未创建的。

 private static final String COL0 = "id";

 private static final String SQL_CREATE =
    "CREATE TABLE " + DB_NAME + " (" + COL0 + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
            COL1 + " TEXT, " + COL2 + " TEXT, " + COL3 + " TEXT, " +
            COL4 + " TEXT, " + COL5 + " TEXT, " + COL6 + " TEXT, " +
            COL7 + " TEXT, " + COL8 + " TEXT, " + COL9 + " TEXT, " +
            COL10 + " TEXT, " + COL11 + " TEXT, " + COL12 + " TEXT, " +
            COL13 + " TEXT);";

COL0和INTEGER PRIMARY KEY之间没有空格。我认为这就是问题所在。 COL0有一个整数值，根据您的代码，我可以理解为String id。

如果问题解决了，请告诉我。感谢。
