This package can be installed with the go get command:
go get github.com/mattn/go-sqlite3
go-sqlite3 is cgo package. If you want to build your app using go-sqlite3, you need gcc. However, after you have built and installed go-sqlite3 with
go install github.com/mattn/go-sqlite3(which requires gcc), you can build your app without relying on gcc in future.
Important: because this is a
CGOenabled package you are required to set the environment variable
CGO_ENABLED=1and have a
gcccompile present within your path.
API documentation can be found here: http://godoc.org/github.com/mattn/go-sqlite3

When creating a new SQLite database or connection to an existing one, with the file name additional options can be given. This is also known as a DSN string. (Data Source Name).
Options are append after the filename of the SQLite database. The database filename and options are seperated by an
?(Question Mark). Options should be URL-encoded (see url.QueryEscape).
This also applies when using an in-memory database instead of a file.
Options can be given using the following format:
KEYWORD=VALUEand multiple options can be combined with the
This library supports dsn options of SQLite itself and provides additional options.
Boolean values can be one of: *

_auth| - | Create User Authentication, for more information see User Authentication | | UA - Username |
string| Username for User Authentication, for more information see User Authentication | | UA - Password |

_loc| auto | Specify location of time format. | | Transaction Lock |
Boolean| When this pragma is on, the SQLITE_MASTER tables in which database can be changed using ordinary UPDATE, INSERT, and DELETE statements. Warning: misuse of this pragma can easily result in a corrupt database file. |
This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build
If you wish to build this library with additional extensions / features. Use the following command.
go build --tags ""
For available features see the extension list. When using multiple build tags, all the different tags should be space delimted.
go build --tags "icu json1 fts5 secure_delete"
| Extension | Build Tag | Description |
| Additional Statistics | sqlitestat4 | This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlitestat4 table.
The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications.
SQLITEENABLESTAT4 is an enhancement of SQLITEENABLESTAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index.
The SQLITEENABLESTAT3 compile-time option is a no-op and is ignored if the SQLITEENABLESTAT4 compile-time option is used | | Allow URI Authority | sqliteallowuriauthority | URI filenames normally throws an error if the authority section is not either empty or "localhost".
However, if SQLite is compiled with the SQLITEALLOWURIAUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way | | App Armor | sqliteapparmor | When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed.
App Armor is not available under
Windows. | | Disable Load Extensions | sqliteomitloadextension | Loading of external extensions is enabled by default.

Please work only with compiled final binaries.
To compile this package on Linux you must install the development tools for your linux distribution.
To compile under linux use the build tag
go build --tags "linux"
If you wish to link directly to libsqlite3 then you can use the
go build --tags "libsqlite3 linux"
When building in an

apk add --update gcc musl-dev
sudo yum groupinstall "Development Tools" "Development Libraries"
sudo apt-get install build-essential
OSX should have all the tools present to compile this package, if not install XCode this will add all the developers tools.
brew install sqlite3

This package supports the SQLite User Authentication module.
To use the User authentication module the package has to be compiled with the tag
sqlite_userauth. See Features.
To create a database protected by user authentication provide the following argument to the connection string
_auth. This will enable user authentication within the database. This option however requires two additional arguments:
_authis present on the connection string user authentication will be enabled and the provided user will be created as an
adminuser. After initial creation, the parameter
_authhas no effect anymore and can be omitted from the connection string.
Example connection string:
Create an user authentication database with user
Create an user authentication database with user
SHA1for the password encoding.
The passwords within the user authentication module of SQLite are encoded with the SQLite function
sqlite_cryp. This function uses a ceasar-cypher which is quite insecure. This library provides several additional password encoders which can be configured through the connection string.
The password cypher can be configured with the key
_auth_crypt. And if the configured password encoder also requires an salt this can be configured with
Operations on the database regarding to user management can only be preformed by an administrator user.
The user authentication supports two kinds of users
User management can be done by directly using the
*SQLiteConnor by SQL.
The following sql functions are available for user management.
| Function | Arguments | Description | |----------|-----------|-------------| |
string| Will authenticate an user, this is done by the connection; and should not be used manually. | |
int| This function will add an user to the database.
adminis an integer identifying if the added user should be an administrator. Only Administrators can add administrators. | |
int| Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag. | |
string| Delete an user from the database. Can only be used by an administrator. The current logged in administrator cannot be deleted. This is to make sure their is always an administrator remaining. |
These functions will return an integer.
// Autheticate user // Create Admin User SELECT auth_user_add('admin2', 'admin2', 1);
// Change password for user SELECT auth_user_change('user', 'userpassword', 0);
// Delete user SELECT user_delete('user');
The following functions are available for User authentication from the
| Function | Description | |----------|-------------| |
Authenticate(username, password string) error| Authenticate user | |
AuthUserAdd(username, password string, admin bool) error| Add user | |
AuthUserChange(username, password string, admin bool) error| Modify user | |
AuthUserDelete(username string) error| Delete user |
When using attached databases. SQLite will use the authentication from the
maindatabase for the attached database(s).

The -binding suffix was added to avoid build failures under gccgo.
In this repository, those files are an amalgamation of code that was copied from SQLite3. The license of that code is the same as the license of SQLite3.
