How to run pure sql in sqlx

The sqlx extends the database/sql library and have Exec|Query method to run the pure sql without argument, but when i tried to run sqlx.Exec it said the sqlx have no Exec method. How to let sqlx run the pure sql method without any argument?

>Solution :

The github.com/jmoiron/sqlx is a package. Packages do not have methods, they may have functions.

Types may have methods. The sqlx.DB type is what you’re looking for. It embeds the *sql.DB type which have a DB.Exec() method, which is promoted and is available on a value of type *sqlx.DB too.

So first you need an *sqlx.DB value, by connecting to the database, something like this:

db, err := sqlx.Connect("postgres", "user=foo dbname=bar sslmode=disable")
if err != nil {
    log.Fatalln(err)
}

Here db is of type *sqlx.DB. Then you may use the Exec() method:

result, err := db.Exec("SELECT * FROM mytable")
