将数据更新到SQLite-android中的问题

Question

这是我的桌子

db.execSQL("CREATE TABLE tbl_groupAccount ( \n" +
        "    ID                 INTEGER PRIMARY KEY AUTOINCREMENT\n" +
        "                               NOT NULL\n" +
        "                               UNIQUE,\n" +
        "    ACCOUNT_GROUP_NAME VARCHAR,\n" +
        "    ACCOUNT_GROUP_TYPE  VARCHAR \n" +
        ");");

并且我用它来将数据更新到表中

public boolean updateAccountGroup(String nameAccountGroup,String groupAccountType, Integer id) {
    boolean result;
    String sql = "UPDATE tbl_groupAccount" +
            " SET ACCOUNT_GROUP_NAME , ACCOUNT_GROUP_TYPE = '" + nameAccountGroup + groupAccountType + "'" +
            "WHERE ID = " + id;

    try {
        SQLiteDatabase database = this.getWritableDatabase();
        database.execSQL(sql);
        database.close();
        result = true;
    } catch (Exception ex) {
        result = false;
    }
    return result;
}

当我单击按钮以将数据更新到表中时，什么也没有发生。并且没有错误发生。并没有更新到表中。有人可以帮助我。请

谢谢

您的更新SQL应该像：

String sql = "UPDATE tbl_groupAccount" +
                " SET ACCOUNT_GROUP_NAME = '" + nameAccountGroup + "' , ACCOUNT_GROUP_TYPE ='"+ groupAccountType + "'" +
                " WHERE ID = " + id;
