|
||||
//
|
||||
// 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.
