The following code example shows how to bind parameters to create parameterized statements.

Single-Use Statements

The Query and Exec functions both accept additional parameters for binding query parameters to values.

rows, _ := db.Query("SELECT Name, Email FROM Users WHERE UserLogin = ?", "mojombo")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                Email string
        )

        rows.Scan(&Name, &Email)
        fmt.Printf("Name = %s, Email = %s\n", Name, Email)
}

Reusable Statements

The Prepare function creates prepared Stmt objects, which can be re-used across multiple Query and Exec calls.

stmt, _ := db.Prepare("SELECT Name, Email FROM Users WHERE UserLogin = ?")
defer stmt.Close()

rows, _ := stmt.Query("mojombo 1")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                Email string
        )

        rows1.Scan(&Name, &Email)
        fmt.Printf("Name = %s, Email = %s\n", Name, Email)
}

rows, _ = stmt.Query("mojombo 2")
defer rows.Close()
for rows.Next() {
        var (
                Name string
                Email string
        )

        rows2.Scan(&Name, &Email)
        fmt.Printf("Name = %s, Email = %s\n", Name, Email)
}
