Question

I’m dealing with an sqlite db in android application.
To update a row in the db I use method of SQLiteDatabase object “update”

SQLiteDatabase.update(String table, ContentValues values, String whereClause, String[] whereArgs)

But here a confusion, how “whereClause” should look like?
Assume I have these values for update.

values.put("name", appInfo.getName());
values.put("package_name", appInfo.getPackageName());
values.put("version_name", appInfo.getVersionName());

I want to update a row where package_mane column equal to “com.mynamespace.db”. How “whereClause” should be written here? Thanks.

Answer 1

You whereClause should look like this:

String whereClause = "package_mane = ?"; // package_name perhaps?
String[] whereArgs = new String[]{"com.mynamespase.db"};

String from whereArgs are used to substitute ? in whereClause.
