CRUD operations on Redshift databases using Golang

Question

Could you please give me some explanations and some code examples on how it would be done (ex: creating tables and inserting data) ? Which library would you advise me to use ?

Thanks !

Answer 1

• Please note the side-effect import of github.com/lib/pq
• After this queries can be run by db.Query() or db.Exec()
• https://golang.org/pkg/database/sql/#example_DB_Query
• https://golang.org/pkg/database/sql/#pkg-examples

import (
    "database/sql"
    "fmt"
    _ "github.com/lib/pq"
)

func MakeRedshfitConnection(username, password, host, port, dbName string) (*sql.DB, error) {

    url := fmt.Sprintf("sslmode=require user=%v password=%v host=%v port=%v dbname=%v",
        username,
        password,
        host,
        port,
        dbName)

    var err error
    var db *sql.DB
    if db, err = sql.Open("postgres", url); err != nil {
        return nil, fmt.Errorf("redshift conn error : (%v)", err)
    }

    if err = db.Ping(); err != nil {
        return nil, fmt.Errorf("redshift ping error : (%v)", err)
    }
    return db, nil
}
