創建數據庫時sqlite異常

Question

我試圖使用下面的SQLite查詢創建表。

private static final String CREATE_EMPLOYEE_TABLE = "CREATE TABLE " + TABLE_EMPLOYEE + "(" 
      + KEY_DOMAIN_ID + " INTEGER PRIMARY KEY," 
      + KEY_FROM + " TEXT," 
      + KEY_TO + " TEXT" + ")"; 

private static final String CREATE_GROUPS_TABLE = "CREATE TABLE " + TABLE_GROUPS + "(" 
     + KEY_USERID + " INTEGER PRIMARY KEY," 
     + KEY_NAME + " TEXT," 
     + KEY_SESSION_TOKEN + " TEXT," 
     + KEY_GROUP_ID + " TEXT," 
     + KEY_GROUP_NAME + " TEXT" + ")";` 

林使用以下代碼來添加元素爲db，

db.addEmployees(new Employee(id,from,to)); 
db.addGroup(new Group(Integer.valueOf(userId),name,session,groupId,groupName)); 

這些查詢的兩個拋出以下錯誤消息

android.database.sqlite.SQLiteException：鄰近「組「：語法錯誤 （code 1）：，while compiling：CREATE TABLE group（userId INTEGER PRIMARY KEY，name TEXT，sessionToken TEXT，groupId TEXT，groupName TEXT）

Answer 1

重命名變量

String TABLE_GROUPS = "group"

爲類似

String TABLE_GROUPS = "groups"

group在sql保留關鍵字。

Check here the list of reserved keywords in SQLite

Answer 2

你的表名不能爲集團，集團是SQLite中的關鍵詞和要也關鍵字

看到SQLite中的另外的關鍵詞列在這裏.. https://www.sqlite.org/lang_keywords.html
