Excel - SQL Query - ## Temp Table
I am trying to create a global temp table using the results from one query, which can then be selected as a table and manipulated further several times without having to reprocess the data over and over.
This works perfectly in SQL management studio, but when I try to add the table through an Excel query, the table can be referenced at that time, but it is not created in Temporary Tables in the tempdb database.
I have broken it down into a simple example.
If I run this in SQL management studio, the result of 1 is returned as expected, and the table ##testtable1 is created in Temporary Tables
set nocount on; select 1 as 'Val1', 2 as 'Val2' into ##testtable1 select Val1 from ##testtable1
I can then run another select on this table, even in a different session, as you'd expect. E.g.
Select Val2 from ##testtable1
If I don't drop ##testtable1, running the below in a query in Excel returns the result of 2 as you'd expect.
Select Val2 from ##testtable1
However, if I run the same Select... into ##testtable1 query directly in Excel, that correctly returns the result of 1, but the temptable is not created.
If I then try to run
Select Val2 from ##testtable1
As a separate query, it errors saying "Invalid object name '##testtable1'
The table is not listed within Temporary Tables in SQL management studio.
It is as if it is performing a drop on the table after the query has finished executing, even though I am not calling a drop.
How can I resolve this?
Read up on global temp tables(GTT). They persist as long as there is a session referencing it. In SSMS, if you close the session that created the GTT prior to using it in another session, the GTT would be discarded. This is what is happening in Excel. Excel creates a connection, executes and disconnects. Since there are no sessions using the GTT when Excel disconnects, the GTT is discarded.
I would highly recommend you create a normal table rather than use a GTT. Because of their temporary nature and dependence on an active session, you may get inconsistent results when using a GTT. If you create a normal table instead, you can be certain it will still exist when you try to use it later.
The code to create/clean the table is pretty simple.
IF OBJECT_ID('db.schema.tablename') IS NOT NULL TRUNCATE TABLE [tablename] ELSE CREATE [tablename]... GO
You can change the truncate to a delete to clean up a specific set of data and place it at the start of each one of your queries.

is it possible you could use a view? assuming that you are connecting to 5 DBs on the same server can you union the data together in a view:
CREATE VIEW [dbo].[testView] AS SELECT * FROM database1.dbo.myTable UNION SELECT * FROM database2.dbo.myTable
Then in excel:
Data> New Query > From Database > FromSQL Server Database
enter DB server
Select the view from the appropriate DB - done :)
OR call the view however you are doing it (e.g. vba etc.)
equally you could use a stored procedure and call that from VBA .. basically anything that moves more of the complexity to the server side to make your life easier :D

Temp tables can be used to store large amounts of data that would otherwise require numerous queries to repeatedly filter that data.
You can absolutely do this. Notice how I'm building a temp table from SQL called 'TmpSql' ...this could be any query you want. Then I set it to recordset 1. Then I create another recordset 2, that goes and gets the temp table data.
Imagine if you were looping on the first cn.Execute where TmpSql is changing.. This allows you to build a Temporary table coming from many sources or changing variables. This is a powerful solution.
cn.open "Provider= ..." sql = "Select t.* Into #TTable From (" & TmpSql & ") t " Set rs1 = cn.Execute(sql) GetTmp = "Select * From #TTable" rs2.Open GetTmp, cn, adOpenDynamic, adLockBatchOptimistic If Not rs2.EOF Then Call Sheets("Data").Range("A2").CopyFromRecordset(rs2) rs2.Close rs1.Close cn.Close
