What is the best way of importing csv data into a db database?
I am using sqlite.
Do I need to go through an intermediate step of converting to SQL? Cheers
You can use any sqlite gui tool like Sqlite studio to import data.

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 have realm database (.realm) from an existing application, which has more than 400k records.
I dug my head in to this for more than 3-4 hours, but I couldn't find any fruitful results towards converting a .realm file in to a sqlite file.
Any data conversion so far has been done manually. People have converted from Core Data to Realm by grabbing the objects from Core Data and then saving them to a Realm.
I imagine your best bet will be similar here. Grab each object from the Realm and then convert it to the tables/rows/and columns in sqlite. Then you can take that file anywhere.
You can open the realm file in Realm Browser & there you have the option to convert the file in to CSV ( File => Export => CSV ). Then you can import that CSV file to mysql database.
If you want sqlite more specifically, You can import tables separately to your sqlite db through SQLiteBrowser . Create or open your database file and select the specific table you want , then you can import table from CSV.
I'm not at home with this, but I found this link hopefully it can help.
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 can I convert my Access database (.accdb) to an SQLite database(.sqlite)?
May be you can use several step algoritm:
1. Export (convert) Access table or query to Excel file
2. Save Excel file as CSV file.
3. Use any SQLLite manager (for example, phpLiteAdmin) to import data from CSV file to exist SQLLite table.
Except Android and IOS, that use SQLLite, there are still webhostings, that use no more database engine, except for SQLLite.
1) If you want to convert a structure of db you shoud use any DB-modeling tools:
create new model from existing Access Database
generate sql scripte for creating SQLite database
use this script in SQL helper
2) If you want to import data from Access Database to your android app. I think you can do case #1, migrate all data from Access Database to temporary SQLite database, save it to asset folder and rewrite from asset to internal SQLite database during first app. start
I'm used to MySQL and PHPMyAdmin - I had to switch over to MSSQL for an ASP.net project, and I'm having tons of trouble. I'm using the express version of SQL 2008, with SQL Server Management Studio. The following are 2 questions I've been struggling with for a while:
1) How do I export the DB schema for the database? The table structure, etc.?
2) How do I export all the data in the database?
Ideally I'd like to have a .sql file that can be run wherever I need the schema or data duplicated, for example a co-worker's computer for a shared project, or online when the project is being hosted.
Thanks!

INFORMATION_SCHEMA is your friend
SELECT * FROM INFORMATION_SCHEMA.TABLES

Otherwise, if you want something pretty looking, download the 14 day trial of SQL Doc (part of SQL Toolbelt) here:

"2) How do I export all the data in the database?"
In what form? .bak files are typically the most useful. http://www.sqlteam.com/article/backup-and-restore-in-sql-server-full-backups
Or were you looking to move the data into MYSQL or Excel or some other program? If you want to move data to MYSQL check here: http://www.google.com/search?q=mssql+to+mysql
