SQLite connection strings

Basic

Data Source=c:\mydb.db;Version=3;

Version 2 is not supported by this class library.

SQLite

In-Memory Database

An SQLite database is normally stored on disk but the database can also be stored in memory. Read more about SQLite in-memory databases here.

Data Source=:memory:;Version=3;New=True;

SQLite

Using UTF16

Data Source=c:\mydb.db;Version=3;UseUTF16Encoding=True;

SQLite

With password

Data Source=c:\mydb.db;Version=3;Password=myPassword;

SQLite

Using the pre 3.3x database format

Data Source=c:\mydb.db;Version=3;Legacy Format=True;

SQLite

With connection pooling

Connection pooling is not enabled by default. Use the following parameters to control the connection pooling mechanism.

Data Source=c:\mydb.db;Version=3;Pooling=True;Max Pool Size=100;

SQLite

Read only connection

Data Source=c:\mydb.db;Version=3;Read Only=True;

SQLite

Using DateTime.Ticks as datetime format

Data Source=c:\mydb.db;Version=3;DateTimeFormat=Ticks;

The default value is ISO8601 which activates the use of the ISO8601 datetime format

SQLite

Store GUID as text

Normally, GUIDs are stored in a binary format. Use this connection string to store GUIDs as text.

Data Source=c:\mydb.db;Version=3;BinaryGUID=False;

Note that storing GUIDs as text uses more space in the database.

SQLite

Specify cache size

Data Source=c:\mydb.db;Version=3;Cache Size=2000;

The Cache Size value measured in bytes

SQLite

Specify page size

Data Source=c:\mydb.db;Version=3;Page Size=1024;

The Page Size value measured in bytes

SQLite

Disable enlistment in distributed transactions

Data Source=c:\mydb.db;Version=3;Enlist=N;

SQLite

Disable create database behaviour

If the database file doesn't exist, the default behaviour is to create a new file. Use the following parameter to raise an error instead of creating a new database file.

Data Source=c:\mydb.db;Version=3;FailIfMissing=True;

SQLite

Limit the size of database

Data Source=c:\mydb.db;Version=3;Max Page Count=5000;

The Max Page Count is measured in pages. This parameter limits the maximum number of pages of the database.

SQLite

Disable the Journal File

This one disables the rollback journal entirely.

Data Source=c:\mydb.db;Version=3;Journal Mode=Off;

SQLite

Persist the Journal File

This one blanks and leaves the journal file on disk after a commit. Default behaviour is to delete the Journal File after each commit.

Data Source=c:\mydb.db;Version=3;Journal Mode=Persist;

SQLite

Controling file flushing

Data Source=c:\mydb.db;Version=3;Synchronous=Full;

Full specifies a full flush to take action after each write. Normal is the default value. Off means that the underlying OS flushes I/O's.

Standard

Data Source=c:\mydb.db;Version=3;

The "Version" key can take value "2" for SQLite 2.x (default) or value "3" for SQLite 3.x

SQLite

SQLite Version 2.X

Data Source=c:\mydb.db;Version=2;

SQLite

Create a new database

Data Source=c:\mydb.db;Version=3;New=True;

SQLite

Using compression

Data Source=c:\mydb.db;Version=3;Compress=True;

SQLite

Specifying Cache Size

The Cache Size value represents the amount of data pages that are held in memory. Try increase this value for speed improvements but don't forget to keep track of the applications memory usage.

Data Source=c:\mydb.db;Version=3;Cache Size=3000;

SQLite

UTF 8

Data Source=c:\mydb.db;Version=3;UTF8Encoding=True;

SQLite

UTF 16

Data Source=c:\mydb.db;Version=3;UTF16Encoding=True;
