Go MySQL Driver is a MySQL driver for Go's (golang) database/sql package

Quick Overview

mattn/go-sqlite3 is a popular SQLite driver for Go that provides a pure Go interface to SQLite3 databases. It allows Go programs to create, read, update, and delete SQLite databases without requiring external dependencies or CGo.

Pros

Pure Go implementation, making it easy to cross-compile and deploy
Supports both in-memory and file-based SQLite databases
Provides a familiar database/sql interface for Go developers
Actively maintained with regular updates and bug fixes

Cons

Performance may be slower compared to CGo-based SQLite drivers
Limited support for some advanced SQLite features
Potential compatibility issues with certain SQLite extensions
May require manual compilation on some platforms due to its pure Go nature

Code Examples

Opening a database connection:

import (
    "database/sql"
    _ "github.com/mattn/go-sqlite3"
)

db, err := sql.Open("sqlite3", "./database.db")
if err != nil {
    log.Fatal(err)
}
defer db.Close()

Executing a simple query:

rows, err := db.Query("SELECT id, name FROM users WHERE age > ?", 18)
if err != nil {
    log.Fatal(err)
}
defer rows.Close()

for rows.Next() {
    var id int
    var name string
    err = rows.Scan(&id, &name)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("ID: %d, Name: %s\n", id, name)
}

Inserting data with prepared statements:

stmt, err := db.Prepare("INSERT INTO users(name, age) VALUES(?, ?)")
if err != nil {
    log.Fatal(err)
}
defer stmt.Close()

_, err = stmt.Exec("John Doe", 30)
if err != nil {
    log.Fatal(err)
}

Getting Started

Install the package:
```
go get github.com/mattn/go-sqlite3
```

Import the package in your Go code:

import (
    "database/sql"
    _ "github.com/mattn/go-sqlite3"
)

Open a database connection:

db, err := sql.Open("sqlite3", "./database.db")
if err != nil {
    log.Fatal(err)
}
defer db.Close()

Start using the database with standard database/sql methods.

Competitor Comparisons

sqlx

16,124

general purpose extensions to golang's database/sql

Pros of sqlx

Provides a higher-level abstraction over database operations, simplifying common tasks
Supports multiple database drivers, not limited to SQLite
Offers convenient methods for scanning query results into structs and slices

Cons of sqlx

Adds an extra layer of abstraction, which may impact performance for simple operations
Requires learning additional API methods and conventions
May not expose all low-level database-specific features

Code Comparison

sqlx:

db, _ := sqlx.Connect("sqlite3", "test.db")
var users []User
db.Select(&users, "SELECT * FROM users WHERE age > ?", 18)

go-sqlite3:

db, _ := sql.Open("sqlite3", "test.db")
rows, _ := db.Query("SELECT * FROM users WHERE age > ?", 18)
// Manual scanning of rows required

Summary

sqlx provides a more convenient and feature-rich API for database operations, supporting multiple drivers and offering easier data mapping. However, it introduces an additional abstraction layer and may not expose all low-level features. go-sqlite3 is a lower-level driver specifically for SQLite, offering direct access to SQLite features but requiring more manual handling of database operations.

gorm

36,742

The fantastic ORM library for Golang, aims to be developer friendly

Pros of gorm

Higher-level abstraction, providing ORM functionality for easier database operations
Supports multiple databases (SQLite, MySQL, PostgreSQL, etc.), not just SQLite
Offers features like migrations, associations, and hooks for more complex data modeling

Cons of gorm

Steeper learning curve due to its more extensive feature set
Potentially slower performance for simple queries compared to direct SQL execution
May introduce unnecessary complexity for projects with basic database needs

Code Comparison

go-sqlite3 (basic query):

rows, err := db.Query("SELECT id, name FROM users WHERE age > ?", 18)
for rows.Next() {
    var id int
    var name string
    rows.Scan(&id, &name)
}

gorm (equivalent query):

var users []User
db.Where("age > ?", 18).Select("id", "name").Find(&users)
for _, user := range users {
    // Access user.ID and user.Name
}

Summary

go-sqlite3 is a low-level SQLite driver for Go, providing direct access to SQLite databases. It's lightweight and efficient for simple SQLite operations. gorm, on the other hand, is a full-featured ORM that supports multiple databases and offers higher-level abstractions for database operations. While gorm provides more functionality and ease of use for complex scenarios, it may introduce overhead for simpler projects where direct SQL queries suffice.

pq

9,065

Pure Go Postgres driver for database/sql

Pros of pq

Designed for PostgreSQL, offering full support for its advanced features
Better performance for large-scale applications and complex queries
Supports PostgreSQL-specific data types and functions

Cons of pq

Limited to PostgreSQL databases, lacking SQLite's portability
Requires a separate PostgreSQL server, increasing setup complexity
May have a steeper learning curve for developers new to PostgreSQL

Code Comparison

pq:

import (
    "database/sql"
    _ "github.com/lib/pq"
)

db, err := sql.Open("postgres", "user=pqgotest dbname=pqgotest sslmode=verify-full")

go-sqlite3:

import (
    "database/sql"
    _ "github.com/mattn/go-sqlite3"
)

db, err := sql.Open("sqlite3", "./foo.db")

Key Differences

pq is specifically for PostgreSQL, while go-sqlite3 is for SQLite
pq requires a connection string with database details, go-sqlite3 uses a file path
pq supports more advanced database features, go-sqlite3 is simpler and more lightweight
go-sqlite3 is better for embedded applications or simple local storage
pq is preferred for larger, more complex applications with higher concurrency needs

Both libraries implement the database/sql interface, allowing for similar usage patterns once the connection is established. The choice between them depends on the specific requirements of your project, such as scalability, portability, and feature needs.

mysql

14,491

Go MySQL Driver is a MySQL driver for Go's (golang) database/sql package

Pros of mysql

Better performance for large-scale applications and concurrent connections
Supports more complex queries and advanced SQL features
Ideal for distributed systems and multi-server setups

Cons of mysql

Requires separate MySQL server installation and configuration
More complex setup and maintenance compared to SQLite
Higher resource consumption, especially for smaller applications

Code Comparison

mysql:

db, err := sql.Open("mysql", "user:password@tcp(127.0.0.1:3306)/dbname")
if err != nil {
    log.Fatal(err)
}
defer db.Close()

go-sqlite3:

db, err := sql.Open("sqlite3", "./database.db")
if err != nil {
    log.Fatal(err)
}
defer db.Close()

Both drivers implement the database/sql interface, making the usage similar. The main difference lies in the connection string format and the underlying database technology.

mysql is better suited for larger applications with complex data structures and high concurrency needs, while go-sqlite3 is ideal for smaller applications, embedded systems, or local development environments due to its simplicity and self-contained nature.

The choice between these drivers depends on the specific requirements of your project, such as scalability, performance needs, and deployment environment.

Installation

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 CGO enabled package, you are required to set the environment variable CGO_ENABLED=1 and have a gcc compiler present within your path.

API Reference

API documentation can be found here.

Examples can be found under the examples 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 (Data Source Name) string.

Options are append after the filename of the SQLite database. The database filename and options are separated 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=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.

Usage

If you wish to build this library with additional extensions / features, use the following command:

go build -tags "<FEATURE>"

For available features, see the extension list. When using multiple build tags, all the different tags should be space delimited.

Example:

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. 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. 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. 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". 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. App Armor is not available under `Windows`.
Disable Load Extensions	sqlite_omit_load_extension	Loading of external extensions is enabled by default. To disable extension loading add the build tag `sqlite_omit_load_extension`.
Enable Serialization with `libsqlite3`	sqlite_serialize	Serialization and deserialization of a SQLite database is available by default, unless the build tag `libsqlite3` is set. To enable this functionality even if `libsqlite3` is set, add the build tag `sqlite_serialize`.
Foreign Keys	sqlite_foreign_keys	This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections. Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma. 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. PRAGMA function_list PRAGMA module_list PRAGMA pragma_list
JSON SQL Functions	sqlite_json	When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically
Math Functions	sqlite_math_functions	This compile-time option enables built-in scalar math functions. For more information see Built-In Mathematical SQL Functions
OS Trace	sqlite_os_trace	This option enables OSTRACE() debug logging. This can be verbose and should not be used in production.
Pre Update Hook	sqlite_preupdate_hook	Registers a callback function that is invoked prior to each INSERT, UPDATE, and DELETE operation on a database table.
Secure Delete	sqlite_secure_delete	This compile-time option changes the default setting of the secure_delete pragma. When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on. The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur. 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
Tracing / Debug	sqlite_trace	Activate trace functions
User Authentication	sqlite_userauth	SQLite User Authentication see User Authentication for more information.
Virtual Tables	sqlite_vtable	SQLite Virtual Tables see SQLite Official VTABLE Documentation for more information, and a full example here

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.

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 in 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 strings:

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 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. 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

// 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).

Extensions

If you want your own extension to be listed here, or you want to add a reference to an extension; please submit an Issue for this.

FAQ

Getting insert error while query is opened.

You can pass some arguments into the connection string, for example, a URI. See: #39
Do you want to cross compile? mingw on Linux or Mac?

See: #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 not for writable. See #50, #51, #209, #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:?cache=shared" (or "file:foobar?mode=memory&cache=shared"). Every connection to this string will point to the same in-memory database.

Note that if the last database connection in the pool closes, the in-memory database is deleted. Make sure the max idle connection limit is > 0, and the connection lifetime is infinite.

For more information see:
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
Trying to execute 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 information see #305.
Error: database is locked

When you get a database is locked, please use the following options.

Add to DSN: cache=shared

Example:
```
db, err := sql.Open("sqlite3", "file:locked.sqlite?cache=shared")
```
Next, please set the database connections of the SQL package to 1:
```
db.SetMaxOpenConns(1)
```
For more information, see #209.
