How to pass a temp table as a parameter into a separate stored procedure

Question

I have a stored procedure that takes an input parameter @CategoryKeys varchar, and parses its contents into a temp table, #CategoryKeys.

Answer 1

Stored proc that uses temp table

CREATE OR ALTER Procedure Engine.TestProcTempTable
AS
BEGIN
  --DROP TABLE IF EXISTS #TestProcTempTable ;
  SELECT * from #TestProcTempTable;
END

Create put data in to temp table which will be used by SP

DROP TABLE IF EXISTS #TestProcTempTable ;
select * into #TestProcTempTable from ;
execute Engine.TestProcTempTable
