This update adds execution statistics of a scalar-valued, user-defined function to the Showplan XML file in SQL Server 2017.
> is it possible to open a recordset and loop through the records in a scalar valued function? Yes, but using SQL Server, in most cases, this is a very bad idea! You can use CURSOR for the task. check the following docs: https://learn.microsoft.com/sql/t-sql/la...
