将 SQL Server 数据库导出到 sqlite（或 SQL Server Compact）的最佳方式

Question

Do someone know what would be the best way to transform a big SQL Server database to sqlite or SQL Server compact ?

SQL Server database should be around 50-70Gb.

There are some examples on internet (script schema) but I didn't find anything concluding about data.

Answer 1

You can use my Exportsqlce tool to create .sql files in sqlite format from a SQL Server database. Then run them using sqlite3.exe

Download command line tools from https://github.com/ErikEJ/SqlCeToolbox/releases/tag/3.5.2

Export2SQLCE.exe "Data Source=(local);Initial Catalog=Northwind;Integrated Security=True" Northwind.sql sqlite

Good luck!

(I also have SSMS and VS extensions that allow you to do this from a GUI)

Answer 2

I just did this too with SqlCeToolbox, actually through the SSMS (Sql Server Management Studio) gui — Export my SQL db to SQLite db in SSMS · Issue #327 · ErikEJ_SqlCeToolbox · GitHub . But it made over 100 .sql script files I had to pipe to sqlite3.

# powershell
dir *.sql | sort name | % { "$_"; cat $_ | sqlite3 newdatabase.db } 

It worked except for 3 parse errors, but I only lost 3 rows. Somehow directly making the sqlite db failed.

By the way, searching the script file dump is a create way to search every table. Search Sqlite Database - All Tables and Columns

sqlite3 database.db .dump | select-string whatever

INSERT INTO mytable VALUES(0,0,0,'whatever',0);

Answer 3

I'm using this software from Code Project:

Convert SQL Server DB to SQLite DB

It connects with your SQL Server and opens Databases to select and select file destination
