Efficiently Counting Rows in SQL with Power Automate: Tips and Tricks

Introduction:

In the realm of Counting Rows in SQL with Power Automate, getting precise results can be a hurdle for many. This article unveils the techniques and strategies to navigate these challenges effectively in SQL Server.

The Challenge with SQL Server Functions

SQL Server offers functions like Count and CountRow, which, while handy, often lead to delegation warnings. This brings up the question: How can we count records in extensive SQL Server tables without these warnings? The answer lies ahead.

Power Automate and SQL: 

Unraveling the Count Conundrum

While counting records might seem elementary, the actual challenge arises due to non-delegable count operations, especially when restricted to the first 2,000 records in a table. But with the right strategies, these limitations can be bypassed.

Example Case Study

Imagine a table storing issues. This table holds 2,500 rows with key columns being – Description, CreateDateTime, and CloseDateTime. Our task? Count the records closed in the past week.

Typically, an app creator might employ the formula:


        CountRows(Filter('[dbo].[Issue]',
                         CloseDateTime > DateAdd(Today(), -7, Days)
                  )
        )
    

This sadly won’t yield accurate results due to non-delegable limitations of the CountRows function. The real challenge is crafting filtered counts based on multiple criteria.

Decoding the Delegation Warning Workaround:

SQL experts often utilize views to sidestep these delegation warnings. By setting up a view that harnesses the SQL Count function, it becomes feasible to generate a single-row result. An alternative is designing a view that outputs the numeric value ‘1’ for every record, facilitating accurate count when summed.


        CREATE VIEW IssueView
        AS
        SELECT
             IssueID,    
             TenantID,
             PropertyID,
             [Description],
             IsEmergency,
             CreateDateTime,
             CloseDateTime, 
             1 AS [One]
        FROM dbo.Issue
    

In Power Apps, modify your formula like:


        Sum(Filter('[dbo].[IssueView]', 
                   CloseDateTime > DateAdd(Today(), -7, Days)), 
            One
        )
    

This approach yields accuracy since the Sum function is delegable, unlike CountRows or CountA.

Power Automate Row Counting:

Testing the Technique

To validate this approach, tests can be run in Management Studio. Using our 2,500-row table as an example, when property ID 35 is matched, it aligns with 54 records. When the Sum function is applied in the application, the count is precise.

Summing Up The Techniques

Navigating the non-delegable limitations of count functions can seem daunting. However, by innovating with custom views and the numeric value ‘1’, we can employ the Sum function – a testament to the adaptability of SQL methods.
