Command the execute sql query and does not clean up data in Table

Question

Hi Team
I have an SP, which writes source and target data to Temp Tables and runs except query to get mismatch details
I am using Exec command to execute source query that writes data to Temp Table, once I execute query using Exec, data is written and immediately #temp table is cleaned, now I cannot use #temp table for comparition.
Is there any way to execute sql query in SP without using EXEC and will hold the data in temp table.

You need to create temp table before EXEC statement and rewrite your dynamic query also as below
declare @source_Sql nvarchar(1000)
,@target_Sql nvarchar(1000)
create table #TempTable1 (name nvarchar(10))
create table #TempTable2 (name nvarchar(10))
set @source_Sql = 'INSERT INTO #TempTable1 SELECT [Name] from Employee'
set @target_Sql = 'INSERT INTO #TempTable2 SELECT [Name] from Employee2'
EXEC (@source_Sql)   
EXEC (@target_Sql)             
select * from #TempTable1 
 Except 
select * from #TempTable2
