Question

我还在学习Android开发，而且我在创建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，但我找不到我错了... 任何帮助都会被贬低！

Answer 1

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

Answer 2

删除NOT NULL列的id。

Answer 3

这两种情况并不相同！请注意，第一种情况下的主键没有NOT NULL。

Answer 4

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，语言TEXT，身份TEXT，地址TEXT，手机TEXT，公司TEXT，网页TEXT，code_postal TEXT，je_suis_un TEXT，ville TEXT，video TEXT）;

组是sql中的一个关键词，你不能将它用作列名，将组更改为sql中不能成为关键字的其他字符串

Sqlite异常，语法错误
