Looking for a quicker way to check files

I couldn't find the post I was thinking of (It'll probably turn up later - now that I've created a new one ;-)

Anyway, here's the basic idea:

1. Set the basic file paths (folder to check and path to output file)

2. Use DIR to generate the list of file names

3. If the file is successfully was generated, import it into a #temp table. Then do some sort of JOIN with your main table to identify the "new" files.  For example, I used an OUTER JOIN to identify files that exist on disk but NOT in the existing db table: "YourMainTable"

	SELECT TOP 100 tmp.*
	FROM   ##TempImport tmp LEFT JOIN YourMainTable main
				ON main.FileName = tmp.FileName
	WHERE  main.FileName IS NULL;

Select all Open in new window

Full code:

<!--- folder to check for files --->
<cfset folderToCheck = "c:\somefolder\">
<!--- output file containing the file names --->
<cfset saveToFile = ExpandPath("./"& CreateUUID() &".txt")>

<!--- generate list of files --->
<cfexecute name = "C:\windows\System32\cmd.exe" 
    arguments = '/C dir /a-d /b "#folderToCheck#" '
    outputFile="#saveToFile#" 
    timeout = "60"
    errorVariable="errorMessage"></cfexecute>

<!--- import into db and compare --->
<cfif FileExists(saveToFile) AND NOT Len(errorMessage)>
	<cfquery name="qImport" datasource="MSSQL">
		<!--- temp storage --->
		CREATE TABLE ##TempImport
		(
			FileName VARCHAR(500)
		);
	
		<!--- import file names --->
		BULK INSERT ##TempImport 
		FROM '#saveToFile#';
		
		<!--- query to find file names that do NOT exist in the existing db table --->
		SELECT TOP 100 tmp.*
		FROM   ##TempImport tmp LEFT JOIN YourMainTable main
					ON main.FileName = tmp.FileName
		WHERE  main.FileName IS NULL;
		
		<!--- cleanup --->
		DROP ##TempImport 
	</cfquery>		
	
	<cfdump var="#qImport#">

	<!--- cleanup temp file --->
	<cfset FileDelete(saveToFile)>
<cfelse>
	ERROR: Temp file not created
	<cfoutput>#errorMessage#</cfoutput>
</cfif>
