Here is my issue. I am using Titanium Appcelerator to build an app that accesses my database and other various things. I have two separate files. One being an et.sql file in readable format and the other et.sql file with a top line of SQLite format 3���# and the rest being ASCII or some text in an unreadable format.
var db = Ti.Database.install('et.sqlite','et');
var db = Ti.Database.open('et');
This produces an sql file that gets installed inside a folder that the app will use in the future.
When using this et.sql file with the header of SQLite format 3Ä# it is accepting it inside Titanium and the app builds with my code, the other file that is formatted it doesn't accept. It seems like it needs to be in sqlite format.
I am using SQLite Manager for Firefox to update my sqlite file with new tables, etc that in turn gets installed in Titanium that produces an sql file. Problem here is I can't seem to reproduce a sql file that is in sqlite format. The previous developer didn't leave any notes on how to do this and I've struggled to produce this file in a format that works. I've looked into using sqlite3 command line, but I've had no luck. How do I get titanium or sqlite for that matter to dump this file in sqlite format so that it can be used inside Titanium?
I am fairly new to sqlite so if I'm overseeing anything just point it out.
You can use the sqlite3 command-line tool to convert between text files containing SQL statements and SQLite database files:
sqlite3 newfile.sqlite < oldfile.sql
sqlite3 oldfile.sqlite .dump > newfile.sql

I am using a GIS program called ArcGIS to create a .dbf file from shapefile data. I have tried opening the .dbf file in sqlite3. sqlite3 stated "Error: file is encrypted or is not a database". What is causing this error? Why can't I open the .dbf in sqlite3?
When I open the dbf file in Excel I have no issues.
Edit: I am new user to Stack Overflow. SO I am confused at why there no explaination for -1 Vote. What does it mean? And if I get no input into why down votes happen, how can I learn to write better questions?
Edit 2: Since getting an answer, I have researched more and understand better that dbf files are old format that has no SQL component to it. Originally I thought (wrongly) if dbf and sqlite are both databases then they must be compatible. When just starting out, basic questions to you may not be so basic to others.
A .dbf file is a dBase database file. SQLite is a different database system with a completely different database file format. SQLite clients are not made to handle .dbf files. So the behavior you see is expected.
If you really need to access this data with a SQLite client, you could use ArcGIS's Create SQLite Database tool and copy the data from the shapefile to a SQLite database.
I have an application in C# that uses System.Data.SQLite. In my case I use a recent version of SQL Lite database, by now I can see that the new versión has released, and int sqlite.org webpage says that is recommended to upgrade the database.
My question is how to upgrade without lost the information in my actual database.
How can I chech the version of the data
Thanks.
EDIT: what I mean is when I create a new database with the sqlite3 library, I guess that the database file, my database.db has a version. When I update the sqlite3 library, I am update the sqlite3 command line, but the database file still has the version that had when I created it.
So if in the new versions for example add new features to the database, for example triggers, foreign keys and so on, if I am not wrong, this features must be in the database file, not in the sqlite3 library, because when I access to the database for example with entity framework, I don't use sqlite3 library, I use System.SQLite.Data library.
am I wrong? the datafile is never update and only the library can be updated?
Thanks.
Upgrading the SQLite library will not have any effect on your database file.
Changes like foreign keys do not affect the database file.
The last change that affected the file format was a long time ago.
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/
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.
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.
