UPLOADING SQLITE DATABASE VALENTINA SERVER ZIP FILE

The next step, and I’m sure there might be better ways to do this, is to copy the library in your project folder which I always like to do, just to make sure I’m testing with the right library file, and to help me make a distribution zip file later on. Tip : If you could not find the file there, use the “locate” statement to determine the location of “libsqlite3.so.0”. You’ll now find the SQLite library in the following location: /usr /lib /i386-linux-gnu /libsqlite3.so.0 (Note: for Raspberry Pi 2 model B /usr /lib /arm-linux-gnueabihf /libsqlite3.so.0):

Sudo apt-get install sqlite3 libsqlite3-dev You also have to keep in mind that, unlike more advanced SQL servers, you manually have to commit changes. Single User implies that the database file can be opened by one application at a time only.

I did a lot of testing with different database engines, but SQLite is clearly the winner when you’re looking for a tiny single user SQL based database engine available that is available on multiple platforms.įirst of all, SQLite stores all it’s data in a single file and is intended for single user only – as with most embedded SQL engines. SQLite can be found on numerous platforms, anything from Android, Apple MacOS X, Apple iOS, Microsoft Windows, Linux, etc. Both of these actually have an embedded version as well, but are much more complex to install and use, much more resource hungry and not as widely supported as one would hope. Typical use of SQLite is when you’d like to use an SQL database to store application data without the need to run a large SQL database like for example MySQL (my favorite) or FireBird. Airbus even uses it planes (for more famous users see Well-Known SQLite users). Well known companies like Apple, Adobe, Microsoft, Skype, Mozilla, and Google use SQLite for some of their products. SQLite is a small SQL database engine used in more applications than you’d think – you’re probably using SQLite already without even knowing it.

Option 2 (when option 1 fails) – OnGetText Event.

Option 1 (best) – Modify your SQL Query.

A TEXT field shows a (memo) in a DBGrid.

2 Installation or distribution of SQLite with your Lazarus application.

Given the above points you can see that it is not as simple as issuing one single command. scp, i.e.: scp /var/lib/tuptime/tuptime.db make this run unattended you need to append your local public ssh key (usually ~/.ssh/id_rsa.pub) to the ~user/.ssh/authorized_keys file on the webserver. Once the file is copied to the webserver you can (and need to) write a web application that reads the content of the DB, prefereably with parameters set by the web user, and then display the results in a table or something.

You need to amend all these jobs so that the file is copied to the webserver after every update.įor the shutdown event this might be a bit tricky because the network might already be down when the tuptime update process is triggered so you cannot copy the file to the server any more. The DB gets updated during startup and shutdown and regularly by a cronjob or a systemd timer.

You can store the DB under a different name on the webserver for each local computer if you need that. This assumes that your local computer is the only process that updates the DB and no other computer synchronizes with the webserver. To keep the DB synchronized you would need to copy it to your webserver every time it is locally updated. From your other question I see that you use tuptime.
