(SQL Server) FTP Sync Upload Tree w/ Must-Match Filename Constraints

Demonstrates how synchronize a directory tree in the upload direction, but only upload files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

    -- This example requires the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    DECLARE @ftp int
    -- Use "Chilkat_9_5_0.Ftp2" for versions of Chilkat < 10.0.0

    -- Possible synchronization modes are:
    -- mode=0: Upload all files
    -- mode=1: Upload all files that do not exist on the FTP server.
    -- mode=2: Upload newer or non-existant files.
    -- mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.
    -- mode=4: transfer missing files or files with size differences.
    -- mode=5: same as mode 4, but also newer files. 

    -- This example will upload all files, but only those files having filenames
    -- that match *.gif and *.eml

    -- Imagine our local directory tree has these files and directories:

    -- 	accentedLatin1.txt
    -- 	accentedUtf8.txt
    -- 	alice.key
    -- 	anter_cert.pem
    -- 	chiliPepper.gif
    -- 	helloWorld.pdf
    -- 	abc/chiliPepper.gif
    -- 	abc/ghk/
    -- 	data/chiliPepper.gif
    -- 	data/xyz/dkimHtmlBody.txt
    -- 	data/xyz/dkimVerifyTest.eml
    -- 	data/xyz/emailForCreateDsn.eml
    -- 	text/frenchUtf8.txt
    -- 	text/helloWorld.txt
    -- 	text/PolishEmailBody.txt
    -- 	text/something/

    EXEC sp_OASetProperty @ftp, 'SyncMustMatch', '*.eml; *.gif'
    DECLARE @mode int
    SELECT @mode = 0
    EXEC sp_OAMethod @ftp, 'SyncRemoteTree', @success OUT, 'c:/temp/subDir1', @mode
    IF @success <> 1
      BEGIN

        RETURN
      END

    EXEC sp_OAMethod @ftp, 'Disconnect', @success OUT

    -- Show the files uploaded.
    EXEC sp_OAGetProperty @ftp, 'SyncedFiles', @sTmp0 OUT
    PRINT @sTmp0
