Querying from the result of another query.

Question

The following query gives me a list of FaxIDs whose file path column does not start with C:\ and that haven't already been identified according to the identified table.
SELECT [FaxID] FROM [FaxQueue]
WHERE [FilePath] NOT LIKE 'C:\%'
AND [FaxID] NOT IN (SELECT [FaxID] FROM [Identified]);
I have some more code that send's an email to alert whoever that the following records don't have a correct filepath.
Now the list of FaxIDs need to be re-used to insert into the identified table. The identified table has just one column which keeps track of which FaxIDs that have been identified as not having a falid file path.
INSERT INTO [identified] VALUES (???)
I don't know what to stick in for the ?s... do I simply copy and paste my first query into the question marks?
How can I "save" the list of FaxIDs from the first query into some kind of data structure so I can send them in an e-mail (sp_send_dbmail)?
-Nothing to see. Move along.

Answer 1

We have 3 possible ways,
1. As subquery.
SELECT * FROM (
SELECT [FaxID]
FROM [FaxQueue]
WHERE [FilePath]
NOT LIKE 'C:\%'
AND [FaxID]
NOT IN (SELECT
[FaxID] FROM
[Identified])
) X
2. Using CTE(common table expression)
;WITH CTE AS (
SELECT [FaxID]
FROM [FaxQueue]
WHERE [FilePath]
NOT LIKE 'C:\%'
AND [FaxID]
NOT IN (SELECT
[FaxID] FROM
[Identified])
SELECT * FROM CTE
3. USING TEMP TABLE.
SELECT [FaxID] INTO #TEMPTABLE
FROM [FaxQueue]
WHERE [FilePath]
NOT LIKE 'C:\%'
AND [FaxID]
NOT IN (SELECT
[FaxID] FROM
[Identified]);
SELECT * FROM #TEMPTABLE
