Logcat错误地说SQLite数据库中没有这样的列--Android SQLite

Question

在这个Logcat的顶部，它说没有名称== Ben10的列。但是，在这个Logcat的底部我已经使用了imagePath，然后是id，然后是name，然后是密码来记录用户。 Ben10a用密码a表示Ben10的名称。所以有一个列名为Ben10。

Answer 1

使用撇号在sql-queries中包含字符串。 所以试试这个：

select * from AppUser where name = 'Bem10'

Answer 2

在这种情况下，[num，name，typ，notnull，comment]表示列，而下面表示像[1,2,3,4,5]或[id，ref，created，modified，name]这样的值

在你的情况下，
Logcat show E / SQLiteLog（1091）:( 1）没有这样的栏目：Ben10
所以你需要检查一下SQL是否正确......

也许你使用

SELECT  * FROM AppUser WHERE Ben10 = xxxxx so that will be crash
