# SQL Fiddle API (UnOfficial)
|
||||
|
||||
## Purpose
|
||||
|
||||
This Go library is aimed to provide an API to operate http://sqlfiddle.com/
|
||||
|
||||
## Usage
|
||||
|
||||
```Go
|
||||
fiddle := NewFiddle("")
|
||||
res, err := fiddle.CreateSchema(Mysql5_6, `create table person(id int not null auto_increment,
|
||||
name varchar(8),
|
||||
birthday datetime,
|
||||
constraint pk__person primary key(id));`)
|
||||
|
||||
ret, err := fiddle.RunSQL(Mysql5_6, res.Code, "select * from person;")
|
||||
```
