Using Python MELTED to turn an Excel row to column

Quickly and effortlessly take a row of data and turn it into columns (star schema). This is an alternative to MS SQL UNPIVOT but unlike MS SQL you don’t need to know the column names.

Invoke SSRS Subscription from Database

Take the first block of code and search by your report name. Take the SQLAgent Job Name and apply it to the msdb.dbo.sp_start_job to fire off your SSRS Subscription.

USE ReportServer
GO

/Execute SSRS Subscription Manually/
/Connect to Database ReportServer/
SELECT
sub.LastStatus
,s.ScheduleID AS SQLAgent_Job_Name
,SUB.Description AS Sub_Desc
,SUB.DeliveryExtension AS Sub_Del_Extension
,C.Name AS ReportName
,C.Path AS ReportPath
FROM ReportServer.dbo.ReportSchedule RS
INNER JOIN Schedule S ON (RS.ScheduleID = S.ScheduleID)
INNER JOIN Subscriptions SUB ON (RS.SubscriptionID = SUB.SubscriptionID)
INNER JOIN [Catalog] C ON (RS.ReportID = C.ItemID AND SUB.Report_OID = C.ItemID)
WHERE C.Name LIKE ‘%AFTEROWL%’ — Enter Report Name to find Job_Name

/Connect to Database MSDB on the Reporting Server/
/Enter SQLAgent_Job_Name to execute the subscription based on Job ID/
EXEC msdb.dbo.sp_start_job @job_name = ‘7229B588-626C-43B9-8B18-028582673464’

Record every keystrokes

In this tutorial I’ll show you how to capture every key the user presses on the keyboard.

Pyautogui

Using pyautogui to automate your daily work or play a video game for you.

Copy the code below into a text file and run it in your Python IDE. You may need to install the three libraries first

pip install webbrowser

pip install time

pip install pyautogui

import webbrowser
import time
import pyautogui

webbrowser.open(‘www.youtube.com’)
print(‘waiting for 6 seconds for youtube to open’)
time.sleep(6)

print(‘clicked search bar’)
step1 = pyautogui.locateOnScreen(“search bar.png”)
pyautogui.click(step1)

print(‘typing’)
pyautogui.typewrite(‘afterowl python’)
time.sleep(3)

print(‘clicking on search button’)
step2 = pyautogui.locateCenterOnScreen(“search button.png”)
pyautogui.click(step2)
time.sleep(3)

print(‘clicking on Python Graph image’)
step3 = pyautogui.locateCenterOnScreen(“python graph.png”)
pyautogui.click(step3)

SQL Order of Operations! You’re not the Doctor.

The SELECT statement you’re running isn’t what it’s cracked up to be. See how SQL really sees your query. This is the SQL Order of Operation.

Batch Delete

Before you go deleting millions of records DON’T! You need to watch this video to understand why you should not delete records in one full swoop but rather in blocks.

Batch Insert

Inserting millions of rows will take a tow on the transaction log. When you’re inserting this much data, your log file will quickly grow and will have potentials to crash your database. To help relieve the pressure of the log file, you’ll want to insert in batches (this is something that is done in SSIS).

Alter Schema

Why should you use many schemas?

Create and Write to a File

If you need a quick way to log all of the current running processes to a text file you’ll want to check out this video. In this video, I’ll show you how to get all of the currently running processes in Task Manager/Activity Monitor and save that information to a text file. Python is small in size and allows the same code to run in both Windows and Mac which is great because you don’t need to recode for the specific OS.

Union vs Union All

So what’s the big difference between Union and Union All? Let’s take a look.
