Database actions - PAD

  POWER AUTOMATE DESKTOP - DATABASE Pre-Requisites Power Automate Desktop Access to database  Under the database action, we have only three sub actions, namely: Open SQL connection Execute SQL statement  Close SQL connection Open SQL Connection The first step is to connect to the database. So, we will use the Open SQL connection action and provide a connection string to establish the connection (the connection string in the video is a sample). When the connection is successful, the connection details is stored in a variable during execution. Execute SQL statement This action can be used to execute SQL queries. Here, I am using select query and the result is stored in a variable of type datatable. Close SQL connection It is a best practice to always close the database connection once the required queries are executed. YAY! BONUS!😮 How to execute a stored procedure using database action?

Power Automate Array Variable

 ARRAY VARIABLES



A variable is a storage space where we can store any type of value. Here, we are gonna explore how to store & access Array variables.

To understand how array variables work, let's use this example of an array:
["FRIENDS", "Money Heist", "Squid Game", "The Big Bang Theory", "Brooklyn 99"]


 PRE-REQUISITE


Let's get started!

STEP 1: Create an Instant Cloud Flow with a Manual Trigger.
STEP 2: Click on "+New Step". Search and select "Variable".
STEP 3: To create a variable, select "Initialize Variable".

Name: ShowsArray
Type: Array
Value: ["FRIENDS", "Money Heist", "Squid Game", "The Big Bang Theory", "Brooklyn 99"]
Initialize Array Variable In Power Automate



STEP 4: Click on "+New Step". Search and select "Append to array variable".
Append to array variable


STEP 5: Select the Array variable and also add a value to be appended.
Name: ShowsArray
Value:  Lucifer
Append to array variable


STEP 6: To check if appending a value worked, let's use compose and test the flow.
In new step, search and select "Compose". In Inputs, select "ShowsArray" from the dynamic content.
Compose and select Dynamic Content



STEP 7: It's time to iterate through each item in the array.
In a New Step, Search "Control" and Select "Apply to each".
Apply to each



STEP 8: In "Select an output from previous step", select "ShowsArray", the array variable.
Each item in Array



STEP 9: We use "Compose" action, to see us iterating through the Array Variable.

Iterating through an Array


STEP 10: To access a particular value among the Array, lets use Compose and the Expression Tab.

Since the Index of array starts from 0, the Index 2, gives us the 3rd value in the Array.

Formula sort a look like this: variables('variablename')[n]

Array Index


It's time to save and test the flow and see how it works!

We can expand each action to see the results of variable.

That concludes Array variable!
