Getting Started with IIAS400Go
Okay, you're sold on the idea. How do you actually start using IIAS400Go? Don't worry, it's not as scary as it sounds! Here’s a simple guide to get you up and running. First, you'll need to have Go installed on your system. If you don't already have it, head over to the official Go website and download the latest version. Follow the installation instructions for your operating system.
Next, you'll need to install the IIAS400Go library. Open your terminal and run the following command:
go get github.com/YouGetGithub/iias400go
This command uses the go get tool to download and install the IIAS400Go library and its dependencies. Once the installation is complete, you can start using the library in your Go programs. To connect to your AS400, you'll need to provide the necessary connection details, such as the hostname or IP address of the AS400, the port number, and the username and password.
Here's a simple example of how to connect to the AS400 and execute a SQL query:
package main
import (
"fmt"
"github.com/YouGetGithub/iias400go"
)
func main() {
conn, err := iias400go.Connect("your_as400_host", "your_username", "your_password")
if err != nil {
fmt.Println("Error connecting to AS400:", err)
return
}
defer conn.Close()
rows, err := conn.Query("SELECT * FROM your_table")
if err != nil {
fmt.Println("Error executing query:", err)
return
}
defer rows.Close()
for rows.Next() {
var column1 string
var column2 int
err := rows.Scan(&column1, &column2)
if err != nil {
fmt.Println("Error scanning row:", err)
return
}
fmt.Println("Column1:", column1, "Column2:", column2)
}
}
In this example, replace "your_as400_host", "your_username", "your_password", and "your_table" with your actual AS400 connection details and the name of the table you want to query. This code connects to the AS400, executes a SQL query to select all columns from the specified table, and then iterates over the rows, printing the values of each column.
Remember to handle errors properly in your code. The iias400go.Connect and conn.Query functions can return errors if something goes wrong, such as an invalid hostname or incorrect credentials. Make sure to check for these errors and handle them appropriately.
This is just a basic example, but it should give you a good starting point for using IIAS400Go in your own projects. The library provides many other functions and features that you can explore, such as executing CL commands, calling RPG programs, and accessing data in various formats. Happy coding!
