Squirrel - fluent SQL generator for Go

or if you prefer using master (which may be arbitrarily ahead of or behind v1):

NOTE: as of Go 1.6, go get correctly clones the Github default branch (which is v1 in this repo).

import "github.com/Guazi-inc/squirrel"

_Note: This project has moved from github.com/lann/squirrel to github.com/Masterminds/squirrel. Lann remains the architect of the project, but we're helping him curate.

Squirrel is not an ORM. For an application of Squirrel, check out structable, a table-struct mapper

Squirrel helps you build SQL queries from composable parts:

import sq "github.com/Masterminds/squirrel"

users := sq.Select("*").From("users").Join("emails USING (email_id)")

active := users.Where(sq.Eq{"deleted_at": nil})

sql, args, err := active.ToSql()

sql == "SELECT * FROM users JOIN emails USING (email_id) WHERE deleted_at IS NULL"

sql, args, err := sq.
    Insert("users").Columns("name", "age").
    Values("moe", 13).Values("larry", sq.Expr("? + 5", 12)).
    ToSql()

sql == "INSERT INTO users (name,age) VALUES (?,?),(?,? + 5)"

Squirrel can also execute queries directly:

stooges := users.Where(sq.Eq{"username": []string{"moe", "larry", "curly", "shemp"}})
three_stooges := stooges.Limit(3)
rows, err := three_stooges.RunWith(db).Query()

// Behaves like:
rows, err := db.Query("SELECT * FROM users WHERE username IN (?,?,?,?) LIMIT 3",
                      "moe", "larry", "curly", "shemp")

Squirrel makes conditional query building a breeze:

if len(q) > 0 {
    users = users.Where("name LIKE ?", fmt.Sprint("%", q, "%"))
}

You can escape question mask by inserting two question marks:

```sql
SELECT * FROM nodes WHERE meta->'format' ??| array[?,?]

will generate with the Dollar Placeholder:

SELECT * FROM nodes WHERE meta->'format' ?| array[$1,$2]
