i try to use sqlite with phonegap on icenium and i have to ask a question (maybe a noob question).
In fact i cant persist my datas structure in sqlite.
I explain, i created two functions on onDeviceReady(),
one is createDB() other is createTables(), and if i erase the createTables() function, my structure erases.
Thanks you in advance, and sorry for my bad english.

I don't want to provide a migration script while changing table schema in realm java. Also, app should not crash and all the previous data should be erased or truncated something similar to fallbackToDestructiveMigration() as room dose?
Realm provides RealmConfiguration.Builder().deleteIfMigrationNeeded()..., where deleteIfMigrationNeeded() does exactly what you are looking for.
i use C++ Builder with SQLite database. I connect with the database through DBExpress. The problem is that DBGrid shows (WIDEMEMO) in every field and not the exact values that the database has.
I dont have this problem with other databases such as Firebird for example.
Why this behaviour? am i missing something with sqlite and how can be fixed.
Do u suggest me use SQLite / Firebird or other embeded database for a small standalone application.
Thanks in advance.
I am using FireDAC in Delphi and had the same problem.
I have resolved this issue by changing the dataset TWideMemoField DisplayValue property from dvClass to dvFull. Now my DBGrid works as expected.
I know this question is old but since it doesn't have any answer selected I will throw in my two cents. I recently came across the same problem and found a solution that might work for you as well.
This problem exists in your C++ DataSet and your SQLite. As it turns out that when you have a field with no defined size especially a text field, that field will be treated like a widememo or Memo in your DBGrid. So, what you need to do is define your text field with specific numbers of characters i.e. VARCHAR(10).
That's what I did and it work for me. I am using MySQL and Delphi with DBGrid.
This is a problem with the DBGrid. It doesn't handle the WIDEMEMO. See link for help with this.

I just wanted to know if there is any way to generate a SQLite database from Poweramc ?
At first sight, it seems not, and Google isn't helping me much on this...
Thank you for your hints ;)
Since there has been no answer, I guess you'll have to prepare your own DBMS definition. I would have suggested to start by making a copy of the ANSI .xdb, but I saw someone mentioning the use of mySQL .xdb.
Update: I have started a DBMS for SQLite 3.
My database name is [chitomiho] and my table name is [trytable].

Dear Inspiron this is a forum question and not meant to be asked here. If you would have just googled it!!!!

I have this issue with Core Data. I am creating a core-data-based application, for one of the tabs, to populate a UITableViewController. Basically, I have read somewhere that there is an issue with providing a pre-populated sqllite file to be used to load up the data. I created a pre-populated data file and at first had issues with Z_METADATA and other anomalies like that. If we are creating our own sqllite file, is there somethign we have to include, such as certain table names etc?
Note, I didnt create teh application with use core data for storage ticked at beginning, so im not sure if that makes a difference.
Doron, take a look and A Blog On Tech for a really great example of how to get what you are trying to do. Basically it's best to let Xcode create the base SQLite DB for you, copy it to your code directory, pre-populate your data there and then finally add it to the project through Xcode.
So while it is possible to work a Core Data application that you haven't created from the beginning in Xcode it is much easier to start from there.
