Get 2 business days

Transact-SQL
1

Hello,

I'm limited with access to SQL Server. I cannot create/execute functions/stored procedures/permanent tables. I'm working with temp tables only.

My query returns thousands of records and it is stored table name #Pop1. One of the column is a date column name EntryDate. I need to calculate 2 business days date (no holidays/weekends) from EntryDate for all records. I already created a temp table which list all days of year and I would be able to tell if a certain date is a business day or not. My query of getting 2 business days is below.

SELECT MAX(DataDate)
FROM (SELECT TOP(2)*
FROM ##tempCalendar
WHERE DataDate > '09-04-2020' AND IsBusinessDay = 1) a;

I'm struggling with how do I join the query from above to table #Pop1 that has all my population that I need, replacing the date '09-04-2020' from the query above to the column name EntryDate in table #Pop1?

Please help.

Thank you.

SELECT ...,

     FROM (SELECT TOP (2) C.DataDate 
           FROM ##tempCalendar C
           WHERE DataDate > P.date_column AND IsBusinessDay = 1
           ORDER BY C.DataDate
          ) AS derived1 
     ) AS finalColumnName
FROM #Pop1 P
