Extracting Value from Specific Column in SharePoint Custom List Based on Internal Name as Variable

[Anonymous]

Hello,

I have a Variable Array that contains the column names ("Tracker Columns").  Its format is:

[
{
"Column Name": "AIO Approval (S)",
"Internal Name": "AIO_x0020_Approval_x0020_Status"
},
{
"Column Name": "Approval Queue (S)",
"Internal Name": "Approval_x0020_Queue_x0020_Statu"
},
{
"Column Name": "BOM Ready (S)",
"Internal Name": "BOM_x0020_Ready_x0020_Status"
}, .....

This Variable Array contains a subset of names found in the SharePoint Custom List - "Tracker."

My goal is to use "Apply to each" to traverse the "Tracker columns," ideally setting a string variable - "New Status Value" - when for the desired columns only.  I have tried using - triggerBody()?variables('Current Internal Name')?['Value'] - whereby the italisized portion of the statement would be variable.  However, when I try to save I get "Expression is invalid."  Note: Current Internal Name has the format - ["AIO_x0020_Approval_x0020_Status"].  (I am unsure how to use concat to create a single quote versus the ones showing.  Thus, I could use a clue.)

Is there a way to feed a variable into a statement as per the example above?  If so, how?

All ideas, insight, and help is very much appreciated.

Cheers.

Hi @Anonymous,

Please take the value from Specific column as below, use the item() to get current item of array, and then use "?" to get element and put the column name in the [''].

Thank you for your insight.

Following your advice I am able to construct a clean statement:

However, using the statement in a subsequent action to derive the value of the target list simply returns the same text:

The hopes were to obtain the value from the triggering list, column AIO_x0020_Approval_x0020_Status.

What might I be missing?

Cheers.

I've spent the better part of another day trying to achieve the goal of 'body' and 'triggerBody' construction based on internal names fed from another Variable Array.  No success!  (The goal is to use only the names within the Tracker Columns array, not all names available within 'body' or 'triggerBody.')  Here's a broader view:

Note that the Condition is always true currently because comparison values evaluate to nulls.  Here are the two statements:

triggerBody()?[concat('''',variables('Tracker Columns')[variables('Loop Count')]?['Internal Name'],'''')]

body('Get_items_-_Tracker_Last_Status')?[concat('''',variables('Last Status Columns')[variables('Loop Count')]?['Internal Name'],'''')]

Any additional clues or am I just not going to be able to use third-element variables to achieve my mission?

As alway, all insight is welcomed and appreciated.

Cheers.

Update:

Using this statement:

concat('body(','''','Get_items_-_Tracker_Last_Status','''',')?[','''',string(variables('Last Status Columns')[variables('Loop Count')]?['Internal Name']),'''',']?[','''','Value','''',']')

I am able to form the desired output:

body('Get_items_-_Tracker_Last_Status')?['AIO_x0020_Approval_x0020__x0028_']?['Value']  (example)

But, obviously I simply get a string and not an executed statement.

Any idea how to turn this into an executed statement?
