SQLite.NET

Type.NET Framework

Class

LibraryUsage System.Data.SQLite.SQLiteConnectionManufacturer SQLite

Basic

Data

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

NotesVersion 2 is not supported by this class library.

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;

Using UTF16

Data

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

With password

Data

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

Using the pre 3.3x database format

Data

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

Format=True;

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=False;Max

Pool Size=100;

Read only connection

Data

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

Only=True;

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

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.

Specify cache size

Data

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

Size=2000;

The Cache Size value measured in bytes

Specify page size

Data

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

Size=1024;

The Page Size value measured in bytes

Disable enlistment in distributed transactions

Data

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

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;

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.

Disable the Journal File

This one disables the rollback journal entirely.

Data

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

Mode=Off;

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;

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.

Finisar.SQLite ADO.NET Data Provider

Type

.NET Framework Class

LibraryUsageFinisar.SQLite.SQLiteConnectionManufacturer

Finisar.SQLite

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 Version 2.X

Data

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

Create a new database

Data

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

Using compression

Data

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

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;

UTF 8

Data

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

UTF 16

Data

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

SQLite3 ODBC Driver

Type

.NET Framework Class

LibraryUsageManufacturerSQLite

Standard

DRIVER=SQLite3 ODBC

Driver;Database=c:\mydb.db;LongNames=0;Timeout=1000;NoTXN=0;

SyncPragma=NORMAL;StepAPI=0;

.NET Framework Data Provider for ODBC

Type.NET Framework Wrapper Class

LibraryUsageSystem.Data.Odbc.OdbcConnectionManufacturer

Microsoft

Use an ODBC driver from .NET

Driver={any odbc driver's

name};OdbcKey1=someValue;OdbcKey2=someValue;

See the respective ODBC driver's connection strings options. The

.net OdbcConnection will just pass on the connection string to the

specified ODBC driver. Read more here.
