==========
[![Build Status](https://travis-ci.org/mattn/go-sqlite3.svg?branch=master)](https://travis-ci.org/mattn/go-sqlite3)
[![Coverage Status](https://coveralls.io/repos/mattn/go-sqlite3/badge.svg?branch=master)](https://coveralls.io/r/mattn/go-sqlite3?branch=master)
[![GoDoc](https://godoc.org/github.com/mattn/go-sqlite3?status.svg)](http://godoc.org/github.com/mattn/go-sqlite3)
Description
-----------
sqlite3 driver conforming to the built-in database/sql interface
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, if you install _go-sqlite3_ with `go install github.com/mattn/go-sqlite3`, you don't need gcc to build your app anymore.
Documentation
-------------
API documentation can be found here: http://godoc.org/github.com/mattn/go-sqlite3
Examples can be found under the `./_example` directory
FAQ
---
* Want to build go-sqlite3 with libsqlite3 on my linux.
Use `go build --tags "libsqlite3 linux"`
* Want to build go-sqlite3 with libsqlite3 on OS X.
Install sqlite3 from homebrew: `brew install sqlite3`
Use `go build --tags "libsqlite3 darwin"`
* Want to build go-sqlite3 with icu extension.
Use `go build --tags "icu"`
* 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: https://github.com/mattn/go-sqlite3/issues/27
* Getting insert error while query is opened.
> You can pass some arguments into the connection string, for example, a URI.
> See: https://github.com/mattn/go-sqlite3/issues/39
* Do you want to cross compile? mingw on Linux or Mac?
> See: 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`.

/*
Package sqlite3 provides interface to SQLite3 databases.
This works as a driver for database/sql.
Installation
go get github.com/mattn/go-sqlite3
Supported Types
Currently, go-sqlite3 supports the following data types.
+------------------------------+
|go | sqlite3 |
|----------|-------------------|
|nil | null |
|int | integer |
|int64 | integer |
|float64 | float |
|bool | integer |
|[]byte | blob |
|string | text |
|time.Time | timestamp/datetime|
+------------------------------+
SQLite3 Extension
You can write your own extension module for sqlite3. For example, below is an
extension for a Regexp matcher operation.
#include <pcre.h>
#include <string.h>
#include <stdio.h>
#include <sqlite3ext.h>
SQLITE_EXTENSION_INIT1
static void regexp_func(sqlite3_context *context, int argc, sqlite3_value **argv) {
if (argc >= 2) {
const char *target = (const char *)sqlite3_value_text(argv[1]);
const char *pattern = (const char *)sqlite3_value_text(argv[0]);
const char* errstr = NULL;
int erroff = 0;
int vec[500];
int n, rc;
pcre* re = pcre_compile(pattern, 0, &errstr, &erroff, NULL);
rc = pcre_exec(re, NULL, target, strlen(target), 0, 0, vec, 500);
if (rc <= 0) {
sqlite3_result_error(context, errstr, 0);
return;
}
sqlite3_result_int(context, 1);
}
}
#ifdef _WIN32
__declspec(dllexport)
#endif
int sqlite3_extension_init(sqlite3 *db, char **errmsg,
const sqlite3_api_routines *api) {
SQLITE_EXTENSION_INIT2(api);
return sqlite3_create_function(db, "regexp", 2, SQLITE_UTF8,
(void*)db, regexp_func, NULL, NULL);
}
It needs to be built as a so/dll shared library. And you need to register
the extension module like below.
sql.Register("sqlite3_with_extensions",
&sqlite3.SQLiteDriver{
Extensions: []string{
"sqlite3_mod_regexp",
},
})
Then, you can use this extension.
rows, err := db.Query("select text from mytable where name regexp '^golang'")
Connection Hook
You can hook and inject your code when the connection is established. database/sql
doesn't provide a way to get native go-sqlite3 interfaces. So if you want,
you need to set ConnectHook and get the SQLiteConn.
sql.Register("sqlite3_with_hook_example",
&sqlite3.SQLiteDriver{
ConnectHook: func(conn *sqlite3.SQLiteConn) error {
sqlite3conn = append(sqlite3conn, conn)
return nil
},
})
Go SQlite3 Extensions
If you want to register Go functions as SQLite extension functions,
call RegisterFunction from ConnectHook.
regex = func(re, s string) (bool, error) {
return regexp.MatchString(re, s)
}
sql.Register("sqlite3_with_go_func",
&sqlite3.SQLiteDriver{
ConnectHook: func(conn *sqlite3.SQLiteConn) error {
return conn.RegisterFunc("regexp", regex, true)
},
})
See the documentation of RegisterFunc for more details.

Working:
Very basic encoding / decoding needed for LDAP protocol
Tests Implemented:
A few
TODO:
Fix all encoding / decoding to conform to ASN1 BER spec
Implement Tests / Benchmarks
