Hi
We are using VFP9 and using this SQP command to open a table.
 
sIncoming_TXTFile = ALLTRIM(GETFILE("TXT",'Select Incoming Portal Text File to import into FoxPro)','TXT File'))
sIncoming_DBFFile = LEFT(sIncoming_TXTFile,LEN(sIncoming_TXTFile)-LEN('.txt')) + '.dbf'

Wondering how I can just close this table?
Thanks

FoxPro can assign an alias name dependent on the current app environment state...
The best way is to open the file prior your SQL command and assign your own (and known) alias:

USE (sIncoming_DBFFile) ALIAS SomeKnownAlias IN 0
SELECT * FROM SomeKnownAlias INTO ...
USE IN SomeKnownAlias

Of course you may find the file in a loop through all open aliases:
lnCnt = AUSED(laAliases)
FOR lnI = 1 TO lnCnt
  IF UPPER(DBF(laAliases[lnI, 1])) == UPPER(sIncoming_DBFFile)
    USE IN (laAliases[lnI, 1])
  ENDIF
NEXT

Remember the fact some SQL SELECTs can also use the same DBF file for the result cursor.

Also your command
sIncoming_DBFFile = LEFT(sIncoming_TXTFile,LEN(sIncoming_TXTFile)-LEN('.txt')) + '.dbf'
can be reduced to:
sIncoming_DBFFile = ForceExt(sIncoming_TXTFile, 'DBF')
