Question

我知道这个问题有一些答案，但我似乎仍然无法让我的工作。我收到错误消息;

04-17 11:35:35.086    2437-2437/com.chris.cv10aajproject E/SQLiteLog﹕ (1)   
AUTOINCREMENT is only allowed on an INTEGER PRIMARY KEY
04-17 11:35:35.090    2437-2437/com.chris.cv10aajproject E/SQLiteLog﹕ (1)
no such table: viewing

我的代码如下：

我的适配器中有InsertData方法，由我的应用程序调用

public long insertData(String posCode,String firstLine ,String town,String county, int roomNum,
                       int askingPrice, int currentOffer, int agreedPrice, String agentName,
                       String agentPhone,String estateAgentNam, int refurb, String Time)
{

    SQLiteDatabase db = helper.getWritableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put(DbHelper.POST_CODE, posCode);
    contentValues.put(DbHelper.FIRST_LINE,firstLine);
    contentValues.put(DbHelper.TOWN,town);
    contentValues.put(DbHelper.COUNTY, county);
    contentValues.put(DbHelper.ROOM_NO,roomNum);
    contentValues.put(DbHelper.ASKING_PRICE,askingPrice);
    contentValues.put(DbHelper.CURRENT_OFFER, currentOffer);
    contentValues.put(DbHelper.AGREED_PRICE,agreedPrice);
    contentValues.put(DbHelper.AGENT_NAME,agentName);
    contentValues.put(DbHelper.AGENT_PHO_NUM, agentPhone);
    contentValues.put(DbHelper.ESTATE_AGENT_NAME,estateAgentNam);
    contentValues.put(DbHelper.REFURB_COST,refurb);
    contentValues.put(DbHelper.TIME_OF_APPOINTMENT,Time);

   long id = db.insert(DbHelper.TABLE_NAME, null, contentValues);
    return id ;

我的on create方法看起来像这样

  public void onCreate(SQLiteDatabase db) {

        try {
            db.execSQL(CREATE_TABLE);
            Message.message(context, "onCreate called");

        } catch (SQLException e) {
            Message.message(context, ""+e);
        }
    }

并且CREATE_TABLE是一个常量，如下所示：

private static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + " (" + UID + "INTEGER PRIMARY KEY AUTOINCREMENT, " + POST_CODE + " VARCHAR(255)," +FIRST_LINE+" VARCHAR(255)," + TOWN + "  VARCHAR(255)  " +
            "" + COUNTY + " VARCHAR(255) ," + ROOM_NO + " INTEGER ," + ASKING_PRICE + " INTEGER , " + CURRENT_OFFER + " INTEGER , " + AGREED_PRICE + "INTEGER , " + AGENT_NAME + " VARCHAR(255)," +
            "" + AGENT_PHO_NUM + " VARCHAR(255), " + ESTATE_AGENT_NAME + " VARCHAR(255), " + REFURB_COST + " VARCHAR(255), " + TIME_OF_APPOINTMENT + " VARCHAR(255));";

欢迎任何建议

Answer 1

您需要在UID和INTEGER

之间添加空格

所以改变

 " (" + UID + "INTEGER PRIMARY KEY AUTOINCREMENT,

到

 " (" + UID + " INTEGER PRIMARY KEY AUTOINCREMENT,

和

"INTEGER , " + AGENT_NAME +

到

" INTEGER , " + AGENT_NAME +

因此将create table语句重写为

private static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + " (" + UID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + POST_CODE + " VARCHAR(255)," +FIRST_LINE+" VARCHAR(255)," + TOWN + "  VARCHAR(255)  " +
            "" + COUNTY + " VARCHAR(255) ," + ROOM_NO + " INTEGER ," + ASKING_PRICE + " INTEGER , " + CURRENT_OFFER + " INTEGER , " + AGREED_PRICE + " INTEGER , " + AGENT_NAME + " VARCHAR(255)," +
            "" + AGENT_PHO_NUM + " VARCHAR(255), " + ESTATE_AGENT_NAME + " VARCHAR(255), " + REFURB_COST + " VARCHAR(255), " + TIME_OF_APPOINTMENT + " VARCHAR(255));";

Answer 2

您的表未创建，因为您的CREATE TABLE SQL命令错误。

您应该在Column Name和Column Type

之间添加空格

TABLE_NAME + " (" + UID + " INTEGER PRIMARY KEY AUTOINCREMENT, // add space before INTEGER PRIMARY KEY AUTOINCREMENT

修正：

private static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + " (" + UID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + POST_CODE + " VARCHAR(255)," +FIRST_LINE+" VARCHAR(255)," + TOWN + "  VARCHAR(255)  " +
        "" + COUNTY + " VARCHAR(255) ," + ROOM_NO + " INTEGER ," + ASKING_PRICE + " INTEGER , " + CURRENT_OFFER + " INTEGER , " + AGREED_PRICE + " INTEGER , " + AGENT_NAME + " VARCHAR(255)," +
        "" + AGENT_PHO_NUM + " VARCHAR(255), " + ESTATE_AGENT_NAME + " VARCHAR(255), " + REFURB_COST + " VARCHAR(255), " + TIME_OF_APPOINTMENT + "  VARCHAR(255));";

Answer 3

您需要添加空格并且在TOWN中缺少逗号，请执行以下操作：

private static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + " (" + UID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + POST_CODE + " VARCHAR(255)," + FIRST_LINE + " VARCHAR(255)," + TOWN + "  VARCHAR(255),  "  + COUNTY + " VARCHAR(255) ," + ROOM_NO + " INTEGER ," + ASKING_PRICE + " INTEGER , " + CURRENT_OFFER + " INTEGER , " + AGREED_PRICE + "INTEGER , " + AGENT_NAME + " VARCHAR(255)," + AGENT_PHO_NUM + " VARCHAR(255), " + ESTATE_AGENT_NAME + " VARCHAR(255), " + REFURB_COST + " VARCHAR(255), " + TIME_OF_APPOINTMENT + " VARCHAR(255));";

Android SQLite（1）没有这样的表：查看错误
