I have created and populated a database using SQLite Toolbox for Visual Studio but find it improper to commit a binary to my CVS.. I was thinking about exporting it as queries that I can then run to create the database with the data.
Unfortunately, I haven't found a way to achieve this from SQLite Toolbox but maybe there some functionality directly from SQLite or another tool I can use for this ?
You can export database as queries in sqlite3 using
sqlite3 your_database.db .dump > queries.sql
This queries.sql file can use for database restore.
To restore
sqlite3 new_database.db < queries.sql
which will create new_database.db

How to import SQLite data into DuckDB? Or is it possible to query the SQLite data files directly from DuckDB? A presentation from author of DuckDB mentioned such a feature.
yes it is possible to scan SQLite db files directly by using the sqlite extension
You first will need to install and load it
INSTALL sqlite_scanner
LOAD sqlite_scanner
CALL sqlite_attach('your_sqlite_db.db');
Then you should be able to query the sqlite tables.
I am working on a database design in MySQL Workbench and would like to use SQLite to make a small demo. I am looking for a way to export my model into SQLite files with tables & relationships set up.
I tried this plugin (https://github.com/tatsushid/mysql-wb-exportsqlite) but it seems that it is not working anymore.
Any suggestions?
I'm trying to open a .sqlite file on Windows, but I don't know how to. Do you know a good program for it?
It contains data for statistical analysis, but I prefer having a .txt file.
I also have a .spatialite file. Can you help me?
If you just want to see what's in the database without installing anything extra, you might already have SQLite CLI on your system. To check, open a command prompt and try:
sqlite3 database.sqlite
Replace database.sqlite with your database file. Then, if the database is small enough, you can view the entire contents with:
sqlite> .dump
Or you can list the tables:
sqlite> .tables
Regular SQL works here as well:
sqlite> select * from some_table;
Replace some_table as appropriate.
SQLite is database engine, .sqlite or .db should be a database. If you don't need to program anything, you can use a GUI like sqlitebrowser or anything like that to view the database contents.

Project: https://github.com/sqlitebrowser/sqlitebrowser
There is also spatialite, https://www.gaia-gis.it/fossil/spatialite_gui/index
My favorite:
https://inloop.github.io/sqlite-viewer/
No installation needed. Just drop the file.
I would suggest using R and the package RSQLite
#install.packages("RSQLite") #perhaps needed
library("RSQLite")
# connect to the sqlite file
sqlite <- dbDriver("SQLite")
exampledb <- dbConnect(sqlite,"database.sqlite")
dbListTables(exampledb)
Very basic question, having a hard time finding an explanation online.
I have a file code.sql that can be run on two different databases, a.db3 and b.db3. I used sqlite a.db3 to open the database in sqlite3. How do I run code.sql on it?
Use the .read code.sql command, or call sqlite3 with the file as input: sqlite3 a.db3 < code.sql.
I am guessing that you are trying to use the sqlite3 command line tool that you can dowload from the sqlite.org website.
I recomend that you use, instead, sqlitestudio http://sqlitestudio.one.pl
This has a feature to execute SQL from a file on a database:
Use DB Browser for SQLite is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite.
You can download the DB Browser at SQLite https://sqlitebrowser.org/
Is there any way to get a SQLite view on a JSON file?
Thanks
On recent versions of SQLite, this is built in. The following:
sqlite3> .mode json
sqlite3> .once out.json
sqlite3> SELECT * from foo;
writes the table foo to out.json.
Or, directly from the command line:
sqlite3 db.sqlite3 '.mode json' '.once out.json' 'select * from foo'
.once, which writes the output of the next SQL command to the indicated file, has been in SQLite since 3.8.5 in 2014.
The .mode json is newer though, added in 3.33.0 in 2020-08. It comes with ubuntu 20.10 but older operating systems are unlikely to have that feature in their built-in SQLite version.
SQLiteStudio (sqlitestudio.pl) can export from sqlite3 database to JSON. SQLiteStudio is C++ Qt-based, open source GPLv3 licensed, Linux/macOS/Windows application with a git repository here: 'pawelsalawa/sqlitestudio'.
There are certainly ways to do this. For example, you could write a custom program that parses the JSON input via your favorite JSON processor and then generate the equivalent SQL statements to create tables, insert the rows, etc. and then import that into a SQLite capable tool (DB Browser for SQLite) to generate the actual SQLite db file.
I suspect you will be hard pressed to find a general purpose tool to accomplish this, as the content of the JSON input could vary widely, and in fact may not map well into a relational database at all.
