SQLite connection strings

• • Basic

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

• 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;
