This process will import text files that arrive in a directory into a table.
It will process every file in the directory with the correct filemask and move the file to an archive directory on completion.
It can be used in conjunction with an ftpget SP to import files from a ftp server (see ftp).


/*
Create the directories c:\Transfer\Archive\
Create these text files in c:\transfer\
bcp1.txt
aaammm0120030101
bbbnnn0220030102
cccooo0320030103

bcp2.txt
abcxyz5320030104
defhhh1020030105
cdezzz1120030106
fsajku9920030107

Create the table
create table BCPData
	(
	fld1 varchar(20) ,
	fld2 varchar(20) ,	
	fld3 int ,
	fld4 datetime
	)
Now run the import
exec ImportFiles 'c:\Transfer\' , 'c:\Transfer\Archive\' , 'bcp*.txt', 'MergeBCPData'

You can now move the files back from  the archive directory to the transfer directory and import again.
If this SP call is scheduled then it will import and archive any files that arrive in the transfer directory with the corect file mask.

Enhancements
	The import should be logged to a table in ImportFiles
	The filename should have the datetime appended to it when archived if you wish to be able to import files with the same name
	The MergeData SP should log the number of records imported
