# Go interface to SQLite.

[![GoDoc](https://godoc.org/crawshaw.io/sqlite?status.svg)](https://godoc.org/crawshaw.io/sqlite) [![Build Status](https://travis-ci.org/crawshaw/sqlite.svg?branch=master)](https://travis-ci.org/crawshaw/sqlite) (linux and macOS) [![Build status](https://ci.appveyor.com/api/projects/status/jh9xx6cut73ufkl8?svg=true)](https://ci.appveyor.com/project/crawshaw/sqlite) (windows)

This package provides a low-level Go interface to SQLite 3. Connections are [pooled](https://godoc.org/crawshaw.io/sqlite#Pool) and if the SQLite [shared cache](https://www.sqlite.org/sharedcache.html) mode is enabled the package takes advantage of the [unlock-notify API](https://www.sqlite.org/unlock_notify.html) to minimize the amount of handling user code needs for dealing with database lock contention.

It has interfaces for some of SQLite's more interesting extensions, such as [incremental BLOB I/O](https://www.sqlite.org/c3ref/blob_open.html) and the [session extension](https://www.sqlite.org/sessionintro.html).

A utility package, [sqlitex](https://godoc.org/crawshaw.io/sqlite/sqlitex), provides some higher-level tools for making it easier to perform common tasks with SQLite. In particular it provides support to make nested transactions easy to use via [sqlitex.Save](https://godoc.org/crawshaw.io/sqlite/sqlitex#Save).

This is not a database/sql driver.

```go get -u crawshaw.io/sqlite```

## Example

A HTTP handler that uses a multi-threaded pool of SQLite connections via a shared cache.

```go

var dbpool *sqlitex.Pool

func main() {

	var err error

	dbpool, err = sqlitex.Open("file:memory:?mode=memory", 0, 10)

	if err != nil {

		log.Fatal(err)

	}

	http.HandleFunc("/", handler)

	log.Fatal(http.ListenAndServe(":8080", nil))

}

func handler(w http.ResponseWriter, r *http.Request) {

	conn := dbpool.Get(r.Context())

	if conn == nil {

		return

	}

	defer dbpool.Put(conn)

	stmt := conn.Prep("SELECT foo FROM footable WHERE id = $id;")

	stmt.SetText("$id", "_user_id_")

	for {

		if hasRow, err := stmt.Step(); err != nil {

			// ... handle error

		} else if !hasRow {

			break

		}

		foo := stmt.GetText("foo")

		// ... use foo

	}

}

```

## Platform specific considerations

By default it requires some pthreads DLL on Windows. To avoid it, supply `CGOLDFLAGS="-static"` when building your application.
