[More documentation is available in our Wiki](https://github.com/mattn/go-sqlite3/wiki)
|
||||
|
||||
## Description
|
||||
|
||||
sqlite3 driver conforming to the built-in database/sql interface
|
||||
|
||||
Supported Golang version:
|
||||
- 1.9.x
|
||||
- 1.10.x
|
||||
|
||||
[This package follows the official Golang Release Policy.](https://golang.org/doc/devel/release.html#policy)
|
||||
|
||||
## Requirements
|
||||
|
||||
* Go: 1.9 or higher.
|
||||
* GCC (Go-SQLite3 is a `CGO` package)
|
||||
|
||||
_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 `CGO` enabled package you are required to set the environment variable `CGO_ENABLED=1` and have a `gcc` compile present within your path.**
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
go get github.com/mattn/go-sqlite3/driver
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
`Go-SQLite3 is an implementation of Go's database/sql/driver interface. You only need to import the driver and can use the full database/sql API then.
|
||||
|
||||
Use `sqlite3` as `drivername` and a valid [DSN](https://github.com/mattn/go-sqlite3/wiki/DSN) as `dataSourceName`:
|
||||
|
||||
```go
|
||||
import (
|
||||
"database/sql"
|
||||
_ "github.com/mattn/go-sqlite3/driver"
|
||||
)
|
||||
|
||||
db, err := sql.Open("sqlite3", "file:test.db")
|
||||
```
|
||||

||||

# API Reference
|
||||
|
||||
API documentation can be found here: http://godoc.org/github.com/mattn/go-sqlite3
|
||||
|
||||
Examples can be found under the [examples](./_example) directory
|
||||
|
||||
# Connection String
|
||||
|
||||
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).
|
||||
|
||||
This also applies when using an in-memory database instead of a file.
|
||||
|
||||
Options can be given using the following format: `KEYWORD=VALUE` and multiple options can be combined with the `&` ampersand.
|
||||
|
||||
This library supports dsn options of SQLite itself and provides additional options.
|
||||
|
||||
Boolean values can be one of:
|
||||
* `0` `no` `false` `off`
|
||||
* `1` `yes` `true` `on`

# Features
|
||||
|
||||
This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build `tags`.
|
||||
|
||||
[Click here for more information about build tags / constraints.](https://golang.org/pkg/go/build/#hdr-Build_Constraints)
|
||||
|
||||
### Usage
|
||||
|
||||
If you wish to build this library with additional extensions / features.
|
||||
Use the following command.
|
||||
|
||||
```bash
|
||||
go build --tags "<FEATURE>"
|
||||
```
|
||||
|
||||
For available features see the extension list.
|
||||
When using multiple build tags, all the different tags should be space delimted.
|
||||
|
||||
Example:
|
||||
|
||||
```bash
|
||||
go build --tags "icu json1 fts5 secure_delete"
|
||||
```
|
||||
|
||||
### Feature / Extension List
|
||||
|
||||
| Extension | Build Tag | Description |
|
||||
|-----------|-----------|-------------|
|
||||
| Additional Statistics | sqlite_stat4 | 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 sqlite_stat4 table.<br><br>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.<br><br>SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. 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.<br><br>The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used |
|
||||
| Allow URI Authority | sqlite_allow_uri_authority | URI filenames normally throws an error if the authority section is not either empty or "localhost".<br><br>However, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY 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 | sqlite_app_armor | 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. <br><br>App Armor is not available under `Windows`. |
|
||||
| Disable Load Extensions | sqlite_omit_load_extension | Loading of external extensions is enabled by default.<br><br>To disable extension loading add the build tag `sqlite_omit_load_extension`. |
|
||||
| Foreign Keys | sqlite_foreign_keys | This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections.<br><br>Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma.<br><br>Enforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default |
|
||||
| Full Auto Vacuum | sqlite_vacuum_full | Set the default auto vacuum to full |
|
||||
| Incremental Auto Vacuum | sqlite_vacuum_incr | Set the default auto vacuum to incremental |
|
||||
| Full Text Search Engine | sqlite_fts5 | When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically |
|
||||
| International Components for Unicode | sqlite_icu | This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build |
|
||||
| Introspect PRAGMAS | sqlite_introspect | This option adds some extra PRAGMA statements. <ul><li>PRAGMA function_list</li><li>PRAGMA module_list</li><li>PRAGMA pragma_list</li></ul> |
|
||||
| JSON SQL Functions | sqlite_json | When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically |
|
||||
| Secure Delete | sqlite_secure_delete | This compile-time option changes the default setting of the secure_delete pragma.<br><br>When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.<br><br>The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur.<br><br>On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted. See the documentation on the secure_delete pragma for additional information |
|
||||
| Secure Delete (FAST) | sqlite_secure_delete_fast | For more information see [PRAGMA secure_delete](https://www.sqlite.org/pragma.html#pragma_secure_delete) |
|
||||
| Tracing / Debug | sqlite_trace | Activate trace functions |
|
||||
| User Authentication | sqlite_userauth | SQLite User Authentication see [User Authentication](#user-authentication) for more information. |
|
||||
|
||||
# Compilation
|
||||
|
||||
This package requires `CGO_ENABLED=1` ennvironment variable if not set by default, and the presence of the `gcc` compiler.
|
||||
|
||||
If you need to add additional CFLAGS or LDFLAGS to the build command, and do not want to modify this package. Then this can be achieved by using the `CGO_CFLAGS` and `CGO_LDFLAGS` environment variables.
|
||||
|
||||
## Android
|
||||
|
||||
This package can be compiled for android.
|
||||
Compile with:
|
||||
|
||||
```bash
|
||||
go build --tags "android"
|
||||
```
|
||||
|
||||

|
||||
|
||||
Building on GCP is not possible because `Google Cloud Platform does not allow `gcc` to be executed.
|
||||
|
||||
Please work only with compiled final binaries.
|
||||
|
||||
## Linux
|
||||
|
||||
To compile this package on Linux you must install the development tools for your linux distribution.
|
||||
|
||||
To compile under linux use the build tag `linux`.
|
||||
|
||||
```bash
|
||||
go build --tags "linux"
|
||||
```
|
||||
|
||||
If you wish to link directly to libsqlite3 then you can use the `libsqlite3` build tag.
|
||||
|
||||
```
|
||||
go build --tags "libsqlite3 linux"
|
||||
```
|
||||
|
||||
### Alpine
|
||||
|
||||
When building in an `alpine` container run the following command before building.
|
||||
|
||||
```
|
||||
apk add --update gcc musl-dev
|
||||
```
|
||||
|
||||

Required dependency
|
||||
|
||||
```bash
|
||||
brew install sqlite3
|
||||
```
|
||||
|
||||
For OSX there is an additional package install which is required if you whish to build the `icu` extension.
|
||||
|
||||
This additional package can be installed with `homebrew`.
|
||||
|
||||
```bash
|
||||
brew upgrade icu4c
|
||||

||||
|
||||
```bash
|
||||
go build --tags "darwin"
|
||||
```
|
||||
|
||||
If you wish to link directly to libsqlite3 then you can use the `libsqlite3` build tag.
|
||||
|
||||
```
|
||||
go build --tags "libsqlite3 darwin"
|
||||
```

|
||||
|
||||
## Windows
|
||||
|
||||
To compile this package on Windows OS you must have the `gcc` compiler installed.
|
||||
|
||||
1) Install a Windows `gcc` toolchain.
|
||||
2) Add the `bin` folders to the Windows path if the installer did not do this by default.
|
||||
3) Open a terminal for the TDM-GCC toolchain, can be found in the Windows Start menu.
|
||||
4) Navigate to your project folder and run the `go build ...` command for this package.
|
||||
|
||||
For example the TDM-GCC Toolchain can be found [here](ttps://sourceforge.net/projects/tdm-gcc/).
|
||||
|
||||
## Errors
|
||||
|
||||
- Compile error: `can not be used when making a shared object; recompile with -fPIC`
|
||||
|
||||
When receiving a compile time error referencing recompile with `-FPIC` then you
|
||||
are probably using a hardend system.
|
||||
|
||||
You can copile the library on a hardend system with the following command.
|
||||
|
||||
```bash
|
||||
go build -ldflags '-extldflags=-fno-PIC'
|
||||
```
|
||||
|
||||

|
||||
|
||||
- Can't build go-sqlite3 on windows 64bit.
|
||||
|
||||
> Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
|
||||
> See: [#27](https://github.com/mattn/go-sqlite3/issues/27)

# User Authentication
|
||||
|
||||
This package supports the SQLite User Authentication module.
|
||||
|
||||
## Compile
|
||||
|
||||
To use the User authentication module the package has to be compiled with the tag `sqlite_userauth`. See [Features](#features).
|
||||
|
||||
## Usage
|
||||
|
||||
### Create protected database
|
||||
|
||||
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:
|
||||
|
||||
- `_auth_user`
|
||||
- `_auth_pass`
|
||||
|
||||
When `_auth` is present on the connection string user authentication will be enabled and the provided user will be created
|
||||
as an `admin` user. After initial creation, the parameter `_auth` has no effect anymore and can be omitted from the connection string.
|
||||
|
||||
Example connection string:
|
||||
|
||||
Create an user authentication database with user `admin` and password `admin`.
|
||||
|
||||
`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin`
|
||||
|
||||
Create an user authentication database with user `admin` and password `admin` and use `SHA1` for the password encoding.
|
||||
|
||||
`file:test.s3db?_auth&_auth_user=admin&_auth_pass=admin&_auth_crypt=sha1`
|
||||
|
||||
### 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 `_auth_salt`.
|
||||
|
||||
#### Available Encoders
|
||||
|
||||
- SHA1
|
||||
- SSHA1 (Salted SHA1)
|
||||
- SHA256
|
||||
- SSHA256 (salted SHA256)
|
||||
- SHA384
|
||||
- SSHA384 (salted SHA384)
|
||||
- SHA512
|
||||
- SSHA512 (salted SHA512)
|
||||
|
||||
### Restrictions
|
||||
|
||||
Operations on the database regarding to user management can only be preformed by an administrator user.
|
||||
|
||||
### Support
|
||||
|
||||
The user authentication supports two kinds of users
|
||||
|
||||
- administrators
|
||||
- regular users
|
||||
|
||||
### User Management
|
||||
|
||||
User management can be done by directly using the `*SQLiteConn` or by SQL.
|
||||
|
||||
#### SQL
|
||||
|
||||
The following sql functions are available for user management.
|
||||
|
||||
| Function | Arguments | Description |
|
||||
|----------|-----------|-------------|
|
||||
| `authenticate` | username `string`, password `string` | Will authenticate an user, this is done by the connection; and should not be used manually. |
|
||||
| `auth_user_add` | username `string`, password `string`, admin `int` | This function will add an user to the database.<br>if the database is not protected by user authentication it will enable it. Argument `admin` is an integer identifying if the added user should be an administrator. Only Administrators can add administrators. |
|
||||
| `auth_user_change` | username `string`, password `string`, admin `int` | Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag. |
|
||||
| `authUserDelete` | username `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.
|
||||
|
||||
- 0 (SQLITE_OK)
|
||||
- 23 (SQLITE_AUTH) Failed to perform due to authentication or insufficient privileges
|
||||
|
||||
##### Examples
|
||||
|
||||
```sql
|
||||
// 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');
|
||||
```
|
||||
|
||||
#### *SQLiteConn
|
||||
|
||||
The following functions are available for User authentication from the `*SQLiteConn`.
|
||||
|
||||
| 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 |
|
||||
|
||||
### Attached database
|
||||
|
||||
When using attached databases. SQLite will use the authentication from the `main` database for the attached database(s).
|
||||

# FAQ
|
||||
|
||||
- Getting insert error while query is opened.
|
||||
|
||||
> You can pass some arguments into the connection string, for example, a URI.
|
||||
> See: [#39](https://github.com/mattn/go-sqlite3/issues/39)
|
||||
|
||||
- Do you want to cross compile? mingw on Linux or Mac?
|
||||
|
||||
> See: [#106](https://github.com/mattn/go-sqlite3/issues/106)
|
||||
> See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html
|
||||
|
||||
- Want to get time.Time with current locale
|
||||
|
||||
Use `_loc=auto` in SQLite3 filename schema like `file:foo.db?_loc=auto`.
|
||||
|
||||
- Can I use this in multiple routines concurrently?
|
||||
|
||||
Yes for readonly. But, No for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209), [#274](https://github.com/mattn/go-sqlite3/issues/274).
|
||||
|
||||
- Why I'm getting `no such table` error?
|
||||
|
||||
Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
|
||||
|
||||
Each connection to :memory: opens a brand new in-memory sql database, so if
|
||||
the stdlib's sql engine happens to open another connection and you've only
|
||||
specified ":memory:", that connection will see a brand new database. A
|
||||
workaround is to use "file::memory:?mode=memory&cache=shared". Every
|
||||
connection to this string will point to the same in-memory database.
|
||||
|
||||

|
||||
|
||||
- Reading from database with large amount of goroutines fails on OSX.
|
||||
|
||||
OS X limits OS-wide to not have more than 1000 files open simultaneously by default.
|
||||
|
||||
For more information see [#289](https://github.com/mattn/go-sqlite3/issues/289)
|
||||
|
||||
- Trying to execure a `.` (dot) command throws an error.
|
||||
|
||||
Error: `Error: near ".": syntax error`
|
||||
Dot command are part of SQLite3 CLI not of this library.
|
||||
|
||||
You need to implement the feature or call the sqlite3 cli.
|
||||
|
||||
More infomation see [#305](https://github.com/mattn/go-sqlite3/issues/305)
|
||||
|
||||
- Error: `database is locked`
|
||||
|
||||
When you get an database is locked. Please use the following options.
|
||||
|
||||
Add to DSN: `cache=shared`
|
||||
|
||||
Example:
|
||||
```go
|
||||
db, err := sql.Open("sqlite3", "file:locked.sqlite?cache=shared")
|
||||
```
|
||||
|
||||
Second please set the database connections of the SQL package to 1.
|
||||
|
||||
```go
|
||||
db.SetMaxOpenConn(1)
|
||||
```
