未创建Android数据库表

Question

在Android中,我很难找到以下查询的问题.编码似乎是正确的.我正在尝试以下代码段:

 DATABASE_TABLES.add("CREATE TABLE PageRights("
                +"RightsId INTEGER NOT NULL,"
                +"PageName varchar(-1) NULL,"
                +"PageId INTEGER NOT NULL,"
                +"UserId INTEGER NOT NULL,"
                +"RoleId INTEGER NOT NULL,"
                +"Add BOOLEAN NOT NULL,"
                +"Edit BOOLEAN NULL,"
                +"Delete BOOLEAN NULL,"
                +"CreatedBy varchar(-1) NULL,"
                +"CreatedDate DATE NOT NULL,"
                +"Views BOOLEAN NULL)");

抛出的错误是;

android.database.sqlite.SQLiteException: near "Add": syntax error (code 1): , while compiling: CREATE TABLE PageRights(RightsId INTEGER NOT NULL,PageName varchar(-1) NULL,PageId INTEGER NOT NULL,UserId INTEGER NOT NULL,RoleId INTEGER NOT NULL,Add BOOLEAN NOT NULL,Edit BOOLEAN NULL,Delete BOOLEAN NULL,CreatedBy varchar(-1) NULL,CreatedDate DATE NOT NULL,Views BOOLEAN NULL)

请提出你的想法,帮助我.

Add,Edit,Delete是预先定义的关键字,下面的方式使用,

DATABASE_TABLES.add("CREATE TABLE PageRights("
                +"RightsId INTEGER NOT NULL,"
                +"PageName varchar(-1) NULL,"
                +"PageId INTEGER NOT NULL,"
                +"UserId INTEGER NOT NULL,"
                +"RoleId INTEGER NOT NULL,"
                +"Add_PageRights BOOLEAN NOT NULL,"
                +"Edit_PageRights BOOLEAN NULL,"
                +"Delete_PageRights BOOLEAN NULL,"
                +"CreatedBy varchar(-1) NULL,"
                +"CreatedDate DATE NOT NULL,"
                +"Views BOOLEAN NULL)");
