# SQL Gen Go

This package takes a directory and builds go types to be used with generated sql query builder.

## Example:

Assume this directory structure

```

./sql 

    /authors

        create.sql

        fetch.sql

        list.sql

```

This tool will build an output like this (annotated in comments):

```go

// Code generated by go generate; DO NOT EDIT.

package sql

// Based on the directory and file authors/create.sql

// parameters from the sql file e.g. :bio and :name are available as part of the struct.

// in the future these params will be able to be annotated with primitives or sql.* types.

type AuthorsCreate struct {

	Bio  interface{}

	Name interface{}

}

// authors/fetch.sql

type AuthorsFetch struct {

	AuthorId interface{}

}

// authors/list.sql (no parameters)

type AuthorsList struct {

}

func (p AuthorsCreate) Build() (string, []interface{}) {

	return "INSERT INTO authors (\n  name, bio\n) VALUES (\n  $1, $2\n)\nRETURNING *;", []interface{}{

		p.Name,

		p.Bio,

	}

}

func (p AuthorsFetch) Build() (string, []interface{}) {

	return "SELECT * FROM authors\nWHERE id = $1 LIMIT 1;", []interface{}{

		p.AuthorId,

	}

}

func (p AuthorsList) Build() (string, []interface{}) {

	return "SELECT * FROM authors\nORDER BY name;", []interface{}{}

}

```

And usage:

```go

package main

import "github.com/dynajoe/sql-gen-go/sql"

func main() {

    query, params := (sql.AuthorsCreate{

        Name: "Joe",

        Bio: "I like databases",

    }).Build()

    // Use query and params with your sql driver of choice

}

```
