【问题描述】：

我还在学习 Android 开发，我在创建 sqlite 数据库表时遇到了问题。这是我的代码的一部分：

private static final String CREATE_ADS_PICTURE = "CREATE TABLE "
        + AdsBDD.TABLE_ADS_PICTURE + "(" + AdsBDD.ID_PICS
        + " INTEGER PRIMARY KEY AUTOINCREMENT ," + AdsBDD.AD_ID
        + " INTEGER NOT NULL," + AdsBDD.PICTURE + " TEXT," + AdsBDD.FOLDER
        + " TEXT," + AdsBDD.ORDER_NO + " INTEGER NOT NULL);";

private static final String CREATE_AGENCES = "CREATE TABLE "
        + AgencesBDD.TABLE_AGENCES + "(" + AgencesBDD.ID
        + " INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL," + AgencesBDD.GROUP
        + " INTEGER," + AgencesBDD.USERNAME + " TEXT," + AgencesBDD.EMAIL
        + " TEXT," + AgencesBDD.CONTACT_NAME + " TEXT,"
        + AgencesBDD.REGISTRATION_DATE + " TEXT," + AgencesBDD.ACTIVATION
        + " TEXT," + AgencesBDD.ACTIVE + " INTEGER," + AgencesBDD.STORE
        + " INTEGER," + AgencesBDD.STORE_BANNER + " TEXT,"
        + AgencesBDD.RATING + " REAL," + AgencesBDD.LANGUAGE + " TEXT,"
        + AgencesBDD.IDENTITY + " TEXT," + AgencesBDD.ADDRESS + " TEXT,"
        + AgencesBDD.PHONE + " TEXT," + AgencesBDD.COMPANY + " TEXT,"
        + AgencesBDD.WEBPAGE + " TEXT," + AgencesBDD.CODE_POSTAL + " TEXT,"
        + AgencesBDD.JE_SUIS_UN + " TEXT," + AgencesBDD.VILLE + " TEXT,"
        + AgencesBDD.VIDEO + " TEXT);";

    @Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(CREATE_ADS_PICTURE);
    db.execSQL(CREATE_AGENCES);
}



   public class AgencesBDD {
public static final String TABLE_AGENCES = "agences";

public static final String ID = "id";
public static final String GROUP = "group";
public static final String USERNAME = "username";
public static final String EMAIL = "email";
public static final String CONTACT_NAME = "contact_name";
public static final String REGISTRATION_DATE = "registration_date";
public static final String ACTIVATION = "activation";
public static final String ACTIVE = "active";
public static final String STORE = "store";
public static final String STORE_BANNER = "store_banner";
public static final String RATING = "rating";
public static final String LANGUAGE = "language";
public static final String IDENTITY = "identity";
public static final String ADDRESS = "address";
public static final String PHONE = "phone";
public static final String COMPANY = "company";
public static final String WEBPAGE = "webpage";
public static final String CODE_POSTAL = "code_postal";
public static final String JE_SUIS_UN = "je_suis_un";
public static final String VILLE = "ville";
public static final String VIDEO = "video";

` 所以问题是 Sqlite 为表 AGENCES 抛出了这个异常，但是表 AD_PICTURE 工作正常：

03-08 14:36:01.892: E/AndroidRuntime(10822): FATAL EXCEPTION: main
03-08 14:36:01.892: E/AndroidRuntime(10822): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.infonetdiffusion.immohabitation/com.infonetdiffusion.immohabitation.FragmentBaseActivity}: android.database.sqlite.SQLiteException: near "group": syntax error (code 1): , while compiling: CREATE TABLE agences(id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,group INTEGER,username TEXT,email TEXT,contact_name TEXT,registration_date TEXT,activation TEXT,active INTEGER,store INTEGER,store_banner TEXT,rating REAL,language TEXT,identity TEXT,address TEXT,phone TEXT,company TEXT,webpage TEXT,code_postal TEXT,je_suis_un TEXT,ville TEXT,video TEXT);

它应该很容易修复，但我找不到我错在哪里...... 任何帮助将不胜感激！

【问题讨论】：

如果您只是打印出您的创建字符串并发布它们可能会容易得多。另外，作为一个快速的猜测，我会说“组”只是一个保留命令，它现在需要一个 GROUP BY 命令。尝试将组更改为随机的，例如“测试”

标签： android sqlite syntax-error

【解决方案1】：

您使用 sqlite 关键字作为列名，即 group sqliteKeyword 这是限制

【讨论】：

就是这样！我不知道这是一个限制词...非常感谢！

【解决方案2】：

删除NOT NULL 的id 列。

【解决方案3】：

这两种情况不等价！请注意，第一种情况下的主键没有NOT NULL。

【解决方案4】：

CREATE TABLE 代理（id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,group INTEGER,username TEXT,email TEXT,contact_name TEXT,registration_date TEXT,activation TEXT,active INTEGER,store INTEGER,store_banner TEXT,rating REAL,语言TEXT,身份TEXT,地址TEXT,电话TEXT,公司TEXT,网页TEXT,code_postal TEXT,je_suis_un TEXT,ville TEXT,视频TEXT);

group是sql中的关键字，不能作为列名，将group改成sql中不能作为关键字的其他字符串
