## Contributing to pq
`pq` has a backlog of pull requests, but contributions are still very
much welcome. You can help with patch review, submitting bug reports,
or adding new functionality. There is no formal style guide, but
please conform to the style of existing code and general Go formatting
conventions when submitting patches.
### Patch review
Help review existing open pull requests by commenting on the code or
proposed functionality.
### Bug reports
We appreciate any bug reports, but especially ones with self-contained
(doesn't depend on code outside of pq), minimal (can't be simplified
further) test cases. It's especially helpful if you can submit a pull
request with just the failing test case (you'll probably want to
pattern it after the tests in
[conn_test.go](https://github.com/lib/pq/blob/master/conn_test.go).
### New functionality
There are a number of pending patches for new functionality, so
additional feature patches will take a while to merge. Still, patches
are generally reviewed based on usefulness and complexity in addition
to time-in-queue, so if you have a knockout idea, take a shot. Feel
free to open an issue discussion your proposed patch beforehand.

`go test` is used for testing. A running PostgreSQL server is
required, with the ability to log in. The default database to connect
to test with is "pqgotest," but it can be overridden using environment
variables.
Example:
PGHOST=/run/postgresql go test github.com/lib/pq
Optionally, a benchmark suite can be run as part of the tests:
PGHOST=/run/postgresql go test -bench .
## Features
* SSL
* Handles bad connections for `database/sql`
* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
* Scan binary blobs correctly (i.e. `bytea`)
* Package for `hstore` support
* COPY FROM support
* pq.ParseURL for converting urls to connection strings for sql.Open.
* Many libpq compatible environment variables
* Unix socket support
* Notifications: `LISTEN`/`NOTIFY`
* pgpass support
## Future / Things you can help with
* Better COPY FROM / COPY TO (see discussion in #181)

/*
Package pq is a pure Go Postgres driver for the database/sql package.
In most cases clients will use the database/sql package instead of
using this package directly. For example:
import (
"database/sql"
_ "github.com/lib/pq"
)
func main() {
db, err := sql.Open("postgres", "user=pqgotest dbname=pqgotest sslmode=verify-full")
if err != nil {
log.Fatal(err)
}
age := 21
rows, err := db.Query("SELECT name FROM users WHERE age = $1", age)
…
}
You can also connect to a database using a URL. For example:
db, err := sql.Open("postgres", "postgres://pqgotest:password@localhost/pqgotest?sslmode=verify-full")
Connection String Parameters
Similarly to libpq, when establishing a connection using pq you are expected to
supply a connection string containing zero or more parameters.
A subset of the connection parameters supported by libpq are also supported by pq.
Additionally, pq also lets you specify run-time parameters (such as search_path or work_mem)
directly in the connection string. This is different from libpq, which does not allow
run-time parameters in the connection string, instead requiring you to supply
them in the options parameter.
For compatibility with libpq, the following special connection parameters are
supported:
* dbname - The name of the database to connect to
* user - The user to sign in as
* password - The user's password
* host - The host to connect to. Values that start with / are for unix domain sockets. (default is localhost)
* port - The port to bind to. (default is 5432)
* sslmode - Whether or not to use SSL (default is require, this is not the default for libpq)
* fallback_application_name - An application_name to fall back to if one isn't provided.
* connect_timeout - Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely.
* sslcert - Cert file location. The file must contain PEM encoded data.
* sslkey - Key file location. The file must contain PEM encoded data.
* sslrootcert - The location of the root certificate file. The file must contain PEM encoded data.
Valid values for sslmode are:
* disable - No SSL
* require - Always SSL (skip verification)
* verify-ca - Always SSL (verify that the certificate presented by the server was signed by a trusted CA)
* verify-full - Always SSL (verify that the certification presented by the server was signed by a trusted CA and the server host name matches the one in the certificate)
See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
for more information about connection string parameters.
Use single quotes for values that contain whitespace:
"user=pqgotest password='with spaces'"
A backslash will escape the next character in values:
"user=space\ man password='it\'s valid'
Note that the connection parameter client_encoding (which sets the
text encoding for the connection) may be set but must be "UTF8",
matching with the same rules as Postgres. It is an error to provide
any other value.
In addition to the parameters listed above, any run-time parameter that can be
set at backend start time can be set in the connection string. For more
information, see
http://www.postgresql.org/docs/current/static/runtime-config.html.
Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html
supported by libpq are also supported by pq. If any of the environment
variables not supported by pq are set, pq will panic during connection
establishment. Environment variables have a lower precedence than explicitly
provided connection parameters.
The pgpass mechanism as described in http://www.postgresql.org/docs/current/static/libpq-pgpass.html
is supported, but on Windows PGPASSFILE must be specified explicitly.
Queries
database/sql does not dictate any specific format for parameter
markers in query strings, and pq uses the Postgres-native ordinal markers,
as shown above. The same marker can be reused for the same parameter:
rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
pq does not support the LastInsertId() method of the Result type in database/sql.
To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres
RETURNING clause with a standard Query or QueryRow call:
var userid int
err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age)
VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid)
For more details on RETURNING, see the Postgres documentation:
http://www.postgresql.org/docs/current/static/sql-insert.html
http://www.postgresql.org/docs/current/static/sql-update.html
http://www.postgresql.org/docs/current/static/sql-delete.html
For additional instructions on querying see the documentation for the database/sql package.
Errors
pq may return errors of type *pq.Error which can be interrogated for error details:
if err, ok := err.(*pq.Error); ok {
fmt.Println("pq error:", err.Code.Name())
}
See the pq.Error type for details.
Bulk imports
You can perform bulk imports by preparing a statement returned by pq.CopyIn (or
pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement
handle can then be repeatedly "executed" to copy data into the target table.
After all data has been processed you should call Exec() once with no arguments
to flush all buffered data. Any call to Exec() might return an error which
should be handled appropriately, but because of the internal buffering an error
returned by Exec() might not be related to the data passed in the call that
failed.
CopyIn uses COPY FROM internally. It is not possible to COPY outside of an
explicit transaction in pq.
Usage example:
txn, err := db.Begin()
if err != nil {
log.Fatal(err)
}
stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age"))
if err != nil {
log.Fatal(err)
}
for _, user := range users {
_, err = stmt.Exec(user.Name, int64(user.Age))
if err != nil {
log.Fatal(err)
}
}
_, err = stmt.Exec()
if err != nil {
log.Fatal(err)
}
err = stmt.Close()
if err != nil {
log.Fatal(err)
}
err = txn.Commit()
if err != nil {
log.Fatal(err)
}
Notifications
PostgreSQL supports a simple publish/subscribe model over database
connections. See http://www.postgresql.org/docs/current/static/sql-notify.html
for more information about the general mechanism.
To start listening for notifications, you first have to open a new connection
to the database by calling NewListener. This connection can not be used for
anything other than LISTEN / NOTIFY. Calling Listen will open a "notification
channel"; once a notification channel is open, a notification generated on that
channel will effect a send on the Listener.Notify channel. A notification
channel will remain open until Unlisten is called, though connection loss might
result in some notifications being lost. To solve this problem, Listener sends
a nil pointer over the Notify channel any time the connection is re-established
following a connection loss. The application can get information about the
state of the underlying connection by setting an event callback in the call to
NewListener.
A single Listener can safely be used from concurrent goroutines, which means
that there is often no need to create more than one Listener in your
application. However, a Listener is always connected to a single database, so
you will need to create a new Listener instance for every database you want to
receive notifications in.
The channel name in both Listen and Unlisten is case sensitive, and can contain
any characters legal in an identifier (see
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
for more information). Note that the channel name will be truncated to 63
bytes by the PostgreSQL server.
You can find a complete, working example of Listener usage at
http://godoc.org/github.com/lib/pq/listen_example.

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.
