使用Golang对Redshift数据库进行CRUD操作

https://golang.org/pkg/database/sql/#pkg-examples

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

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 connect error : (%v)"), err
    }

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