Question

我想在Android应用程序上尝试一些Sqlite请求，

编辑：我的名字列：

private static final String NOM_BDD = "sms.db";
private static final int VERSION_BDD = 1;

private static final String COL_ID = "ID";
private static final int NUM_COL_ID = 0;

private static final String TABLE_SMS_SENT = "table_sms_sent";
private static final String COL_DateSending = "dateSending";

private static final String TABLE_SMS_RECEIVED = "table_sms_received";
private static final String COL_DateReceiving = "dateReceiving";

private static final int NUM_COL_DateReceiving = 1;

private static final String COL_PROCESSED ="processed";
private static final int NUM_COL_PROCESSED = 2;

private static final String COL_PHONE ="phone";
private static final int NUM_COL_PHONE= 3;

private static final String COL_DATA ="data";
private static final int NUM_COL_DATA= 4;

我的要求就在这里：

private static final String CREATE_BDD_SMS_RECEIVED = "CREATE TABLE " + TABLE_SMS_RECEIVED + " ("
        + COL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COL_DateReceiving + " TEXT, "
        + COL_PROCESSED + " TEXT, " + COL_PHONE + "TEXT, " + COL_DATA + "TEXT)";

编辑：在'TEXT'之前删除一些空格

private static final String CREATE_BDD_SMS_RECEIVED = "CREATE TABLE " + TABLE_SMS_RECEIVED + " ("
        + COL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COL_DateReceiving + "TEXT, "
        + COL_PROCESSED + "TEXT, " + COL_PHONE + "TEXT, " + COL_DATA + "TEXT)";

我的myBaseSqlite类的OnCreate就在这里：

@Override
public void onCreate(SQLiteDatabase db) {
    //on créé la table à partir de la requête écrite dans la variable CREATE_BDD sent et received
    db.execSQL(CREATE_BDD_SMS_RECEIVED);
}

然后在我的MainActivity上：

    CSmsReceiverDAO cSmsReceiverDAO = new CSmsReceiverDAO(this);
    CSmsReceived SmsReceived1 = new CSmsReceived.SmsReceivedBuilder().Id(0)
            .Data("coords XY").DateReceiving("janvier").Phone("+33565456").Processed("zz").build();

    cSmsReceiverDAO.open();

    try {
        cSmsReceiverDAO.persist(SmsReceived1);
    } catch (Exception e) {
        e.printStackTrace();
    }

我相信有趣的错误行在这里：

E/SQLiteDatabase: Error inserting zz=2 coords XY=4 janvier=1 +33565456=3

android.database.sqlite.SQLiteException: near "XY": syntax error: , while compiling: INSERT INTO table_sms_received(zz,coords XY,janvier,+33565456) VALUES (?,?,?,?)

编辑：我的持久代码： @覆盖 public void persist（CSmsReceived t）抛出异常{

    //Création d'un ContentValues (fonctionne comme une HashMap)
    ContentValues values = new ContentValues();
    //on lui ajoute une valeur associé à une clé (qui est le nom de la colonne dans laquelle on veut mettre la valeur)
    values.put(t.getDateReceiving(), NUM_COL_DateReceiving);
    values.put(t.getProcessed(), NUM_COL_PROCESSED);
    values.put(t.getPhone(), NUM_COL_PHONE);
    values.put(t.getData(), NUM_COL_DATA);

    //on insère l'objet dans la BDD via le ContentValues
    bdd.insert(TABLE_SMS_RECEIVED, null, values);
}

我的OnCreate似乎有效，但我的persist（）不起作用，它会出错：

E/SQLiteDatabase: Error inserting zz=2 coords XY=4 janvier=1 +33565456=3
                                                                        android.database.sqlite.SQLiteException: near "XY": syntax error: , while compiling: INSERT INTO table_sms_received(zz,coords XY,janvier,+33565456) VALUES (?,?,?,?)

但是我没看到错误语法在哪里..

感谢您帮助我;）

Answer 1

首先：您的CREATE TABLE语句在两个地方的单词TEXT之前缺少空格。这将导致您的表的列名与您定义的常量不同。

第二：您的INSERT声明不正确。括号中的第一组术语应该是列名，而不是您要插入的值。我不知道你的实际列名，但声明看起来应该更像这样：

INSERT INTO table (data, data_receiving, phone, processed) 
    VALUES ('coords XY', '+33565456', 'janvier', 'zz');

或者只是

INSERT INTO table (data, data_receiving, phone, processed) VALUES (?, ?, ?, ?);

修改

构建ContentValues时，values.put()的参数相反。它应该是第一列和第二列，例如

values.put(t.getData(), NUM_COL_DATA); -> value.put(NUM_COL_DATA, t.getData());

SQLiteException：接近“XY”：语法错误（代码1）：
