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.
Website: http://sqlitebrowser.org/
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)

I've recovered data from a formatted hard drive for use in a lawsuit. The data is Skype logs, which are stored in SQLite3 databases. Unfortunately, the disk was formatted and a new copy of OS X was installed on the drive. I scanned the drive and found the files I am looking for, but it seems that the database I'm after is corrupt.
I tried the following command I found by searching on SO:
$ sqlite3 mydata.db ".dump" | sqlite3 new.db
Unfortunately, dumping this way excludes the table of records I'm looking for (Messages). Since I can get the format of the DB from Skype by just logging in with another account and generating a new main.db for it, do I have any additional options for extracting the contents of the corrupt DB? Failing that, is there a way to export the raw contents of the database in a text file or something? I only care about grabbing certain messages, which I can search for.
When the database is corrupt, the ".dump" command extracts all of the usable information, but then ends with a ROLLBACK because it encountered corruption.
Instead, store the output in a file:
$ sqlite3 mydata.db ".dump" > mydata.dump
Then, you can view the data directly in that file, or you can change the last line from "ROLLBACK" to "COMMIT" using a text editor. After that, you can load the valid portion of the data into a database using:
$ sqlite3 new.db < mydata.dump
First check for the PRAGMA integrity_check in command console and click on play button, note down the errors and repair them seperately or try exporting and then importing SQL file to new database and restart the database, it generally removes the slug files stored in the cache. If the above method does not work out then you can try SQLite database recovery tool https://www.recoveryandmanagement.com/repair-sqlite-database-manually/
I am a newbie to sqlite3.
I have some files which contain a .db file and also another file which contains the definition s of many tables. I try to open with notepad and see that it has create table definitions of many files.
I am trying to read them in sqlite3 in linux.
I try to use .read FILENAME after which I try to see the tables by giving .tables command.
I cant see them.
Is there a way I need to source the file or execute.
Thanks for your help in advance
I haven't done anything with SQLite in a long time, but when I did work with it I used a Firefox extension that made it easy.
Check out SQLite Manager to open the DB file:
https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/
.read FILENAME already executes the sql script in the FILENAME. Check if your .db file is writable and/or if the sql contained your file is correct.
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:

I am working on a firm application in which I need to create a local database on my device.
I create my local database through create statement[ It works well]
Then I use that file and perform insert operation through fire-fox sqlite plugin, I need to insert aprox 2000 rows at a time so I can not use code. I just run insert manually through sqlite plugin in fir-fox.
After that I just use that file in my place of my local database.
When I run select query through my code, It show Exception:java.lang.Exception: Exception: In create or prepare statement in DBnet.rim.device.api.database.DatabaseException: SELECT distinct productline FROM T_Electrical ORDER BY productline: file is encrypted or is not a database
I got the solution of this problem, I was doing a silly mistake by creating a file manually by right click in my RES folder, that is not correct. We need to create the database completely from SQlite plugin, then it will work fine. "Create data base from SQLITE(FIle too) and perform insertion operation from SQLITE, then it will work fine"
This is very rare problem, but i think it might be helpful for someone like me....!:)
You should check to see if there is a version problem between the SQLite used by your Firefox installation and that on the BlackBerry. I think I had the same error when I tried to build a database file with SQLite version 2.
You also shouldn't need to create the database file on the device. To create large tables I use a Ubuntu machine and the sqlite3 command line. Create the file, create the tables, insert the data and build indexes. Then I just copy the file onto the device in the proper directory.
For me it was a simple thing. One password was set to that db. I just used it and prolem got solved.
I have a sqlite file but I don't know what tables there are in it and thus I can't use a SELECT query.
So, is there a way to know what table are in it ?
P.S. I am under Ubuntu Linux and I have already installed sqlite3 from shell.
You can open the database using sqlite3 using:
sqlite3 <databasefile>
Once in the sqlite3 shell you can simply type:
.tables
to see a list of all the tables.
You can see the table structure of a particular table using:
.schema <tablename>
You can also omit the table name to see the schema for the whole database.
Information about these commands and more can be seen by typing:
