Html5 sqlite Database?

Is there anyway to to upload a client side framework and upload it as html content so that you can connect to a database that does not have to link out to the web? -- for example a restaurant database etc.
thx

Hi Deep,
Yes you can use SAP IU5 to create the required mobile application.
You can refer to the link below to view demo applications such as Approve purchase orders or Shopping Cart:

Please close your previous threads by marking helpful posts as answer before you start a new one.
The type of the image columns should be BLOB. And make sure that you are looking at the inkCanvas_DB.db in the output folder of your .exe ([your_project_foder]/bin/Debug or [your_project_foder]/bin/Debug) because it is this database that the data gets written
to unless you specify an absolute path in the connection string:
string stConn = @"Data Source=C:\Your_Project_Folder\inkCanvas_DB.db;Version=3";

How to determine the connection string to a SQLite database, in C# code

Hello. I'm trying to figure out how to specify the connection string to a SQLite database, I would like to access using the following code:
string connectionString = null;
SqlConnection connection;
SqlCommand command;
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds1 = new DataSet();
string sql = "SELECT DataName, Data, Id, UserId, DateLastUpdated FROM MainTable";
connectionString = "Data Source=C:\\SQLITEDATABASES\\SQLITEDB1.sqlite;Version=3;";
connection = new SqlConnection(connectionString);
try
connection.Open();
command = new SqlCommand(sql, connection);
catch
The value I assigned to the variable connectionString, in the code above, I obtained somewhere from the Internet. It does not work. I'm using Visual Studio 2013, against the file sqlite-netFx451-setup-bundle-x86-2013-1.0.96.0.exe, which
I installed, and got from
here.
My application's App.config file looks as follows:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="DC_Password_Saver.Properties.Settings.DC_Password_SaverConnectionString" connectionString="data source="C:\Users\patmo_000\Documents\Visual Studio 2013\Projects\DC Password Saver\DC Password Saver\DC Password Saver.db"" providerName="System.Data.SQLite.EF6"/>
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.1"/>
</startup>
</configuration>
I tried to use the value assigned to connectionString in the XML settings above, replacing single backslash characters with double backslash characters, because the Visual Studio editor flagged them as unrecognizable, and wound up with the
following.
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds1 = new DataSet();
string sql = "SELECT DataName, Data, Id, UserId, DateLastUpdated FROM MainTable";
connectionString = "data source="C:\\Users\\patmo_000\\Documents\\Visual Studio 2013\\Projects\\DC Password Saver\\DC Password Saver\\DC Password Saver.db"";
connection = new SqlConnection(connectionString);
The above code however does not work either. So again, does anyone know how I can specify in C# code, a connection string to access my SQLite database? Thanks in advance for your reply.

What does SQLite connection strings has to do with WPF?
You will find some valid connection strings here:
https://www.connectionstrings.com/sqlite/
But you cannot use the SqlConnection class to connect to a SQLite database. You will need to download and add a reference to the System.Data.SQLite library and then use the SQLiteConnection class:
connection = new System.Data.SQLite.SQLiteConnection(connectionString);
try
connection.Open();
command = new System.Data.SQLite.SQLiteCommand(sql, connection);
catch
Please refer to the following article for more information and an example of how to connect and read and write data from an SQLite database using C#:
http://blog.tigrangasparian.com/2012/02/09/getting-started-with-sqlite-in-c-part-one/.
There is contains a link where you can download the required assemblies.
Hope that helps.

[SOLVED] PowerDNS (pdns) - SQLite database '...' does not exist yet

PowerDNS 3.2-5 is having some issues connecting to my backend database (sqlite3).
beta powerdns # tail /var/log/errors.log
May 7 20:12:41 localhost pdns[19098]: Caught an exception instantiating a backend: Unable to launch gsqlite3 connection: SQLite database '/etc/powerdns/database.sqlite' does not exist yet
But when i do:
beta powerdns # sqlite3 /etc/powerdns/database.sqlite
SQLite version 3.7.16.2 2013-04-12 11:52:43
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> select * from domains;
1|<myhostname>|||NATIVE||
sqlite>
sqlite3 It fetches the records and domains to my liking but not PowerDNS.
Same thing goes for a blank db without any domains or records, i can query it but not PowerDNS.
Followed this guide in order to setup the proper tables and columns: http://doc.powerdns.com/html/gsqlite.html#idp9379264
(without the DNSSEC part, i'll give that a go later on)
It obviously loads the sqlite3 module, and tries to connect to the backend, which doesn't work, so the ArchLinux package is fine i'm guessing.
More info:
* Link to package: https://www.archlinux.org/packages/comm … 6_64/pdns/
* chmod == 777
* chown == nobody:nobody (and tried root:root as default)
* running as root (not pdns)
Last edited by Torxed (2013-05-08 10:52:05)

Solved it.
The guides are vague in this regard but once you've just read the config twice you'll understand the logic.
First of all, no absolute paths for sqlite3, it should be:
launch=gsqlite3
gsqlite3-database=database.sqlite
Secondly, find your chroot, and point it to your database location or put your database here (whichever):
chroot=/var/empty
The folder structure should be:
/var/empty/database.sqlite
And this py pointing to ./database.sqlite when starting sqlite3 in pdns, it should be able to lock on to the database.
Peachy!

SQLITE database has no tables on device?

Hello -
When I try to run my app on my iPhone, the sqlite database is found, etc., HOWEVER, when I query it, it says the table doesn't exist. In fact none of the tables do.
Do I have to do something special to get the database and its tables over to the phone itself?
Thanks

Is the database that's part of the application bundle populated, or is it only the database that was created in the simulators Documents folder that is populated?

Is it possible to to use SQlite database as an External Content type?

Hi guys,
I need some help in accessing data from an external database(SQlite) and use it in sharepoint 2010. I have a list in sharepoint 2010 but some of the fields must come from SQlite database. Whenever the list is updated, the corresponding
fields from SQlite database should also be updated.
I've been looking on some examples on using external content types but I've only encountered examples using SQL server. I'm new to sharepoint 2010 and I have little idea to get this done. Can someone kindly assist me on this?
Thank you very much.
Regards,
Peter

Hi Peter,
SharePoint is designed to use Business Connectivity Services when talking to external data sources.
The Microsoft Business Connectivity Services (BCS) can connect to external data from the following types of databases:
Microsoft SQL Server
Oracle
OLE DB
ODBC
So you may connect to SQLite through ODBC. Take a look at this example how to connect to MySQL through ODBC
Connecting MySQL using BCS. You may create an External Content Type for SQLite the same way.

Including sqlite database in a windows air installer

I am trying to create a cross platform air installer that uses a sqlite database.
This is the code I use to copy the database from the installer to the users application directory:
var dataFile:File = File.applicationDirectory.resolvePath("data/myDataStorage.db");
var dataUserFile:File = File.documentsDirectory.resolvePath("myDataStorage.db");
When using the database I access it here:
var file:File = File.documentsDirectory.resolvePath("myDataStorage.db");
This works great on a mac. On a PC it does not work. Can anyone recommend a resource or give me a tip or two?
Thanks

I have been looking into this problem. It turns out that it is not just a Windows problem it also happens on a Mac. Here is what is happening:
I am trying to copy a sqlite .db from the read only application directory to the users documents directory.
First I setup these vars:
    var dbFile:File = File.applicationDirectory.resolvePath("db/myDataStorage.db");
     var dbWorkedFile:File = File.documentsDirectory.resolvePath("myDataStorage.db");
If I do this it works:
dbFile.copyTo(dbWorkedFile, true); //If I set the overwrite param to 'true' then it works.
If I use this code:
dbFile.copyTo(dbWorkedFile);
or
dbFile.copyTo(dbWorkedFile, false);
I get the following error:
Error #3012: Cannot delete file or directory.
    at flash.filesystem::File/copyTo()
The funny thing is that I the destination documents directory will get a 4k blank file when the error occurs. In addition if I try the same copy code on an image I get the same error but the whole image does get copied.
In the end I want my code to do something like the following so that it copies the database over only if it does not exist. If I run this code now I get a 4k .db file and a 3012 error. Any ideas?
public function copyDB():void
                var dbFile:File = File.applicationDirectory.resolvePath("db/myDataStorage.db");
                var dbWorkedFile:File = File.documentsDirectory.resolvePath("myDataStorage.db");
                if(!dbWorkedFile.exists){
                    trace("db Does Not Exist");
                    dbFile.copyTo(dbWorkedFile);
                } else {
                    trace("db Exists so do nothing");
                dbConn = new SQLConnection();
                dbConn.openAsync(dbWorkedFile);

How to copy sqlite database from applicationDirectory to documentsDirectory

I am having problems using the ‘File’ function in Adobe Flex to copy a sqlite database from the read only applicationDirectory to the users documentsDirectory. When I use the code below the only thing that appears in the user documentsDirectory is a 1k to 4k file. The actual file size of the database is around 350k.
Am I not giving the file enough time to copy over?
I am developing on a Mac but I think I remember duplicating the error on a PC as well. This bug has been keeping me from launching my app for far too long. Any ideas would be appreciated.
Here is the code I am using:
public function copyDB():void
          var dbFile:File = File.applicationDirectory.resolvePath("db/myDataStorage.db");
          var dbWorkedFile:File = File.documentsDirectory.resolvePath("myDataStorage.db");
          if(!dbWorkedFile.exists){
                    trace("db Does Not Exist");
                    dbFile.copyTo(dbWorkedFile);
          } else {
                    trace("db Exists");
                    //The database has already been installed. Launch app.
          dbConn = new SQLConnection();
          dbConn.openAsync(dbWorkedFile);
I got the above code from this Adobe Cookbook recipe:
http://cookbooks.adobe.com/post_Include_existing_SQLite_database_in_an_AIR_applica-10483.h tml
Thanks

I got it working.
I tried the copyToAsync method and it did not work. While testing the copyToAsync I found a path that brought me to the
'preinitialize' phase of the application startup sequence.
I fixed it by calling my copyDB() function from the 'preinitialize' call in the windowedApplication tag like:
preinitialize="copyDB()".
I had been calling it from the applicationComplete phase of startup. Now it seems so obvious.
Thanks again for sending me down the path that finally fixed it.

Creating sqlite database from code

Hi,
I am writing integration test with sqlite database.Before running a test,I want to create a database using a script ie .sql file.Is it possible to do so using Flex API for databases? If so,how?

@kinganand - Currently I don't know of an equivalent to DbUnit for AIR, so you'd have to roll something of your own accord. Maybe search Google Code or GitHub for projects that may have attempted to tackle this problem?

SQLite Database and TLF Text in Flash CS5

I encountered the following problem when working with the built-in sqlite database and using TLF TextFields in Flash CS5
When I tried to use TLF TextFields alone, I don't face any probelem,
but when I start using a database connectivity code, the TLF TextFields placed on the stage are not shown, but instead, the SWF file is showing the built-in preloader with five dots looping.
I tried changing the default Linkage in ActionScript 3 Settings to Merge Mode, but in this case nothing is shown, not the textfields, neither the preloader.
I think the problem is related to loading the TLF Text Engine, but I couldn't figure out what to do.
The following is my code placed in first frame:
==========================================
import flash.data.SQLConnection;
import flash.events.SQLErrorEvent;
import flash.events.SQLEvent;
import flash.filesystem.File;
var conn:SQLConnection = new SQLConnection();
conn.addEventListener(SQLEvent.OPEN, openHandler);
conn.addEventListener(SQLErrorEvent.ERROR, errorHandler);
// The database file is in the application directory
var folder:File = File.applicationDirectory;
var dbFile:File = folder.resolvePath("DBSample.db");
conn.openAsync(dbFile);
function openHandler(event:SQLEvent):void
    trace("the database was created successfully");
function errorHandler(event:SQLErrorEvent):void
    trace("Error message:", event.error.message);
    trace("Details:", event.error.details);
stop();
==========================================
and I am using one TLF TextField on the stage for later use.
Publish Settings>> Player: AIR 2.6
and not to forget, when I test the file using Contol Panel >> Test in Air Debug Launcher (Desktop), the file is working correctly.
but when I open the generated SWF file, the problem appears.
I hope that I find some help
Thanks.

Insert SQLite database into a phone app

Would like to use a sqlite database in my android/ios phone app how would I be able to implement this into my project?

Thank you for your response. Anouther question is now that i have the database in the app and running, how would i call the database to get specific information. Example: I have a database which consists of students name on the columns and on the rows i have homerooms, the apps purpose is to find the students id number by matching the rows and columns to get the student id number.
Also there are multiple dataabases, for the different schools. that would need to accesed locally on the phone.
How would i acomplish this using dreamweaver. Please see example below
Screen one would ask for School name which you would pick
Screen two would ask for the homeroom
Screen three would ask for students name
Screen Four would tell you there ID number
Thank you for your great answers and quick responses
