android.database.sqlite.SQLiteException:没有这样的表:CLTABLE(代码1):,同时编译:INSERT INTO表

Question

嘿,我创建了我的数据库,并希望插入一些字段初始化,但得到一个sqliteexception没有这样的表,而编译时无法插入到表中.忘记了id值-1,我没有得到确切的错误.

public long insertData(String name, String number, String email, String jobtype, String uri, String msg)
{
    SQLiteDatabase db = database.getWritableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put(database.NAME, name);
    contentValues.put(database.NUMBER, number);
    contentValues.put(database.EMAIL, email);
    contentValues.put(database.JOBTYPE, jobtype);
    contentValues.put(database.URI, uri);
    contentValues.put(database.MSG, msg);
    long id = db.insert(database.TABLE_NAME, null, contentValues);
    return id;
}

 static class Database extends SQLiteOpenHelper{

    private static final String DATABASE_NAME="cloudicadatabase";
    private static final String TABLE_NAME="CLTABLE";
    private static final int DATABASE_VERSION= 1;
    private static final String COLUMN_UID = "_id";
    private static final String NAME="Name";
    private static final String NUMBER="Number";
    private static final String EMAIL="Email";
    private static final String JOBTYPE="Jobtype";
    private static final String URI="Uri";
    private static final String MSG="Msg";
    private static final String CREATE_TABLE = "CREATE TABLE" + TABLE_NAME + "(" +
            COLUMN_UID + "INTEGER PRIMARY KEY AUTOINCREMENT, " +
            NAME + "VARCHAR(32) NOT NULL, " +
            NUMBER + "INTEGER, " +
            EMAIL + "VARCHAR(25) NOT NULL, " +
            JOBTYPE + "VARCHAR(20) NOT NULL, " +
            URI + "VARCHAR(50) NOT NULL, " +
            MSG + "VARCHAR(500) NOT NULL);";
    private static final String DROP_TABLE = "DROP TABLE "+TABLE_NAME+" IF EXISTS";

    private Context context;
    public Database(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
        this.context = context;
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        try {
            db.execSQL(CREATE_TABLE);
        } catch (SQLException e) {
            Message.message(context, ""+e);
        }

    }
main.java

public void submit(View view)
{
    String nam = name.getText().toString();
    String numb = num.getText().toString();
    String mail = email.getText().toString();
    String jtype = job.getText().toString();
    String ur = uri.getText().toString();
    String msag = msg.getText().toString();

    long id = database.insertData(nam, numb, mail, jtype, ur, msag);

    if (id < 0)
    {
        Message.message(this, "Unsucessful");
    }
    else {
        Message.message(this, "Submited");
    }

Answer 1

你的桌子没有创建,所以你得到了NPE.

你应该在Column Name和之间添加空格Column Type

 private static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + "(" +
        COLUMN_UID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
        NAME + " VARCHAR(32) NOT NULL, " +
        NUMBER + " INTEGER, " +
        EMAIL + " VARCHAR(25) NOT NULL, " +
        JOBTYPE + " VARCHAR(20) NOT NULL, " +
        URI + " VARCHAR(50) NOT NULL, " +
        MSG + " VARCHAR(500) NOT NULL);";
