-[![Build Status](https://drone.io/github.com/jmoiron/sqlx/status.png)](https://drone.io/github.com/jmoiron/sqlx/latest) [![Godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/jmoiron/sqlx) [![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/jmoiron/sqlx/master/LICENSE)
-
-sqlx is a library which provides a set of extensions on go's standard
-`database/sql` library.  The sqlx versions of `sql.DB`, `sql.TX`, `sql.Stmt`,
-et al. all leave the underlying interfaces untouched, so that their interfaces
-are a superset on the standard ones.  This makes it relatively painless to
-integrate existing codebases using database/sql with sqlx.
-
-Major additional concepts are:
-
-* Marshal rows into structs (with embedded struct support), maps, and slices
-* Named parameter support including prepared statements
-* `Get` and `Select` to go quickly from query to struct/slice
-
-In addition to the [godoc API documentation](http://godoc.org/github.com/jmoiron/sqlx),
-there is also some [standard documentation](http://jmoiron.github.io/sqlx/) that
-explains how to use `database/sql` along with sqlx.
-
-## Recent Changes
-
-* sqlx/types.JsonText has been renamed to JSONText to follow Go naming conventions.
-
-This breaks backwards compatibility, but it's in a way that is trivially fixable
-(`s/JsonText/JSONText/g`).  The `types` package is both experimental and not in
-active development currently.
-
-More importantly, [golang bug #13905](https://github.com/golang/go/issues/13905)
-makes `types.JSONText` and `types.GzippedText` _potentially unsafe_, **especially**
-when used with common auto-scan sqlx idioms like `Select` and `Get`.
-
-### Backwards Compatibility
-
-There is no Go1-like promise of absolute stability, but I take the issue seriously
-and will maintain the library in a compatible state unless vital bugs prevent me 
-from doing so.  Since [#59](https://github.com/jmoiron/sqlx/issues/59) and 
-[#60](https://github.com/jmoiron/sqlx/issues/60) necessitated breaking behavior, 
-a wider API cleanup was done at the time of fixing.  It's possible this will happen
-in future;  if it does, a git tag will be provided for users requiring the old
-behavior to continue to use it until such a time as they can migrate.
-
-## install
-
-    go get github.com/jmoiron/sqlx
-
-## issues
-
-Row headers can be ambiguous (`SELECT 1 AS a, 2 AS a`), and the result of
-`Columns()` does not fully qualify column names in queries like:
-
-```sql
-SELECT a.id, a.name, b.id, b.name FROM foos AS a JOIN foos AS b ON a.parent = b.id;
-```
-
-making a struct or map destination ambiguous.  Use `AS` in your queries
-to give columns distinct names, `rows.Scan` to scan them manually, or 
-`SliceScan` to get a slice of results.
-
-## usage

-[sqlx_test.go](https://github.com/jmoiron/sqlx/blob/master/sqlx_test.go) for more
-usage.

-# reflectx
-
-The sqlx package has special reflect needs.  In particular, it needs to:
-
-* be able to map a name to a field
-* understand embedded structs
-* understand mapping names to fields by a particular tag
-* user specified name -> field mapping functions
-
-These behaviors mimic the behaviors by the standard library marshallers and also the
-behavior of standard Go accessors.
-
-The first two are amply taken care of by `Reflect.Value.FieldByName`, and the third is
-addressed by `Reflect.Value.FieldByNameFunc`, but these don't quite understand struct
-tags in the ways that are vital to most marshalers, and they are slow.
-
-This reflectx package extends reflect to achieve these goals.

-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.
