Updating sqlite database versions?

In order to upgrade the Database in Android you should increment the DATABASE_VERSION by one, in order for the SQLOpenHelper to know that it must called the onUpgrade method.

In order to upgrade the Database in Android you should increment the DATABASE_VERSION by one, in order for the SQLOpenHelper to know that it must called the onUpgrade method. Rembember This only work when you call getWritableDatabase() otherwise it won't upgrade. And if you change the version and call getReadableDatabase it will show an exception throw new SQLiteException("Can't upgrade read-only database from version " + db.getVersion() + " to " + mNewVersion + ": " + path); But Why?

You see when you call getWritableDatabase the code check wether the version is the same: if (version! = mNewVersion) { db. BeginTransaction(); try { if (version == 0) { onCreate(db); } else { if (version > mNewVersion) { onDowngrade(db, version, mNewVersion); } else { onUpgrade(db, version, mNewVersion); } } db.

SetVersion(mNewVersion); db. SetTransactionSuccessful(); } finally { db.endTransaction(); } }.

– tyczj 2 days ago wherever you are going to use it... I in general use it in my ContentProvider but if you don't have one, it should goes fluently in your code, any where you are going to insert or update a getWritableDatabase has to be called, it's not necesary to force it's use. – Necronet 2 days ago.

I suggest you increment DATABASE_VERSION by one, that will lead the application to call onUpgrade().

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
