//
// Name       : SQL_MFS
//
// Description: MFS for passing records to the SQL data tables
//
// Notes:       To install this MFS, use the SET_MFS(Table, "SQL_MFS*LSL2", 1) command to add it to
//              the end of the MFS chain. NOTE: for the best results. Make sure you are in
//              development engine with the database manager open. Then run the SET_MFS
//              command followed by running the menu option Database:Save in the DB Manager. 
//
// Parameters:																					
//    Code	    [in] -- An integer value indicating the operation to be performed (1 = read a
//                      record, 4 = delete a record, 11 = open a file, etc.)
//    BFS		[in] -- The list of MFSs and the BFS name for the current file or volume. This
//                      is a subvalue mark-delimited array, with the current MFS name as the
//                      first value in the array, and the BFS name as the last value.
//    Handle	[in] -- The file handle of the file or media map being accessed.
//    Name	    [in] -- The name (key) of the record or file being accessed.
//    FMC		[in] -- Various functions.
//    Record	[in] -- The entire record (for record-oriented functions) or a newly-created
//                      handle (for "get handle" functions).
//    Status	[in] -- A return code indicating the success or failure of an operation.
//
// History (Date, Initials, Notes)																
//    01/04/00   pcs   Original programmer
//    01/20/00   pcs   CLEARFILE requires the Arev table name to be removed before processing
//    05/20/05   axf   Process will now also track the accessing of records.
//    11/26/07   dmb   Code clean-up. No functional changes were made.
//    03/08/21	 dmb   Refactor method to store the OpenInsight table name so this MFS will
//					   chain forward correctly with other MFS routines.
