You can download it from the Valentina Studio Homepage or additionally for Mac users in the Mac App Store. If I could find a downside then it would be that the SQL generated in the visual designer cannot be copied with the current freeware version.

Valentina Studio is a pretty darn good editor for SQLite (and others) and is available for MacOS X, Linux and Windows in either a freeware version or a commercial version. Valentina Studio – Cross platform and free Quite a few of these tools are commercial or only useful under Windows, but some offer a trial or freeware version. An overview of available tools can be found on the SQLite Management Tools Page. There are several ways and tools to get your database populated with tables and such. You can populate the empty database with SQLite3Connection.ExecuteDirect(SQLStatements) or with the help of some tools. It’s an empty database of course, but it’s there. The cool part of using SQLite with the TSQLite3Connection is that when you connect to a database file (with SQLite3Connection.Open ), and the file doesn’t exist, then SQLite will create one for you. When you start your project however, you will most likely not have that file yet … SQLiteLibraryName : = '/usr/lib/libsqlite3.dylib' Īs mentioned before: SQLite uses a single file for an entire database. SQLiteDefaultLibrary : = 'libsqlite3.so' Also note that the path under Raspbian is different. Copying it will copy the actual binary, not the link. Note : libsqlite3.so.0 is actually just a symbolic link to a particular library version, for example libsqlite3.so.0.8.6. Note : I noticed that in some forums that people mention ‘/usr/lib64’ for 64-bit systems, but I cannot confirm this to be true or not. In the example below we have our project files saved in ~ /Desktop /MyProject and in this step we will also rename the file to libsqlite3.so .įinally, we’d like Lazarus to find the library during design time and for that we make a soft link in the /usr /lib / directory which we will call ‘libsqlite3.so’ as well (it’s what Lazarus will be looking for).

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):

#FREE PASCAL DATETIME INSTALL#

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.
