## Introduction

## Python script changes

This sample also includes a customized version of the Python script used to connect to the database server. The script is fully compatible with the B&R script. See Automation Studio help (e046127f-e239-4f17-bd17-3ae889dac782) and the [WIKI](https://github.com/br-automation-community/mappDatabase-Demo/wiki) for more details how to use the script.

#### The script changes include:

- Added more and detailed error messages

- Print all SQL queries and server response details

- Trim data type string when reading from database

- Change MsSQL database provider to 'ODBC Driver 17 for SQL Server' to support Linux systems

- Removed dependency from MySql driver for data conversion. It is no longer required to install MySQL driver when using MsSQL.



## Requirements (current used versions)

* Automation Studio 4.9

* mapp 5.14

* Automation Runtime B4.83

Recommended task class is #8 with a 10ms cycle time. For the nettime and axis tasks use #1
