android:在sqlite中创建表时出错？

我在android中创建了一个应用程序，用于执行crud操作。在应用程序中，已成功创建数据库文件，但在创建表时出错，下面是Logcat错误和数据库适配器类

Logcat错误

下面是我的数据库适配器类

请任何人帮我解决这个错误

感谢您

您的SQL中两列之间缺少一个逗号：

private static final String SQL_CREATE_ENTRIES = "CREATE TABLE " +  
        TABLE_NAME + "(" + TIMERECORDS_COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
        TIMERECORDS_COLUMN_TIME + " TEXT **,%Comma goes here%** " + TIMERECORDS_COLUMN_NOTE + " TEXT);";

TIMERECORDS\u COLUMN\u TIME+TEXT==TIMERECORDS\u COLUMN\u TIME+TEXT

你忘了，查尔

下次阅读异常并更准确地查看代码。

看起来您在创建表DDL中缺少了一个逗号。在TIMERECORDS\u列\u TIME列上

在这里：

您可以获得时间文本注释文本，但不使用逗号来分隔它们

Sqlite没有将其检测为语法错误：它以非类型化数据库的形式启动，然后添加了对类型关联的支持，但仍然允许对列类型规范进行各种垃圾处理
