创建数据库时sqlite异常

Question

我试图使用下面的SQLite查询创建表。

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" + ")";` 

林使用以下代码来添加元素为db，

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

这些查询的两个抛出以下错误消息

android.database.sqlite.SQLiteException：邻近“组“：语法错误 （code 1）：，while compiling：CREATE TABLE group（userId INTEGER PRIMARY KEY，name TEXT，sessionToken TEXT，groupId TEXT，groupName TEXT）

Answer 1

重命名变量

String TABLE_GROUPS = "group"

为类似

String TABLE_GROUPS = "groups"

group在sql保留关键字。

Check here the list of reserved keywords in SQLite

Answer 2

你的表名不能为集团，集团是SQLite中的关键词和要也关键字

看到SQLite中的另外的关键词列在这里.. https://www.sqlite.org/lang_keywords.html
