problem about sqlite database, no such table:

Question

I open a sqlite database and use rawquery to get data.

But the log.e show the information:

android.database.sqlite.SQLiteException: no such t

Answer 1

If this is on the emulator, use DDMS File Explorer or adb pull to download a copy of the database file and confirm its contents.

And i crate a custom SQLiteOpenHelper to copy this file to path : /data/data/com.SGMalls/databases/mallMapv2.sqlite

If you are attempting to copy the file in SQLiteOpenHelper's onCreate(), you are too late. I would do it before then.

So the copy file code may be can not copy the complete file.

It is more likely you would get an error about a corrupt file in that case.

Answer 2

If you have multiple contents providers, you might think that your table exists while it does not. In which case the error you are getting is legitimate.

Answer 3

SQLiteDatabase.execSQL() interpretation takes a single string sql, ending with ";". Two lines have not interpreted.

Creating tables in a few lines sql just not executed.

Answer 4

I think this error occurs when you change the table structure. To solve this, clean the data (Settings -> Manage application -> Clear data) before installing the new application.
