SQLite connection strings


  • Basic

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

    Version 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=True;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

  • 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

  • Standard

    DRIVER=SQLite3 ODBC Driver;Database=c:\mydb.db;LongNames=0;Timeout=1000;NoTXN=0;

.NET Framework Data Provider for ODBC

  • 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.
