[string]$sGCIMask = $sDirName + "\" + $sFileNameMask
[string]$sEventLogMessage = "### Cleanup Script Started... ###`r`n"

# Functions and Procedures...
function fGetFileModTime([string]$sFileName) {
  $vFileInfo = get-childitem $sFileName
  return $vFileInfo.lastwritetime 
}

# Start Main script...
if (Test-Path $sDirName) {
get-childitem $sGCIMask | 
    % { 
        # Get File Last Write Time...
        [datetime]$dFileModTime = fGetFileModTime($_.fullname)
        if ($dFileModTime -lt (Get-date).AddDays(-90)) {
        remove-item $_.fullname
        $sEventLogMessage = $sEventLogMessage + "File " + $_.fullname + " (" + $dFileModTime.DateTime + ") removed...`r`n"

MySQL Table Cleanup Procedure

2012-09-05 / MySQL Server / Tim van Kooten Niekerk

With the following procedure, it is possible to move data from a primary table to a secondary table for archival purposes. This specific example moves data on the basis of a date column in the primary table. The number of days (related to the current date/time) to remain in the primary table is passed to the procedure. Start procedure with ‘CALL pCleanUPTable (35)’.

DELIMITER //

CREATE PROCEDURE pCleanUpTable(IN iDays INT)

  BEGIN
    START TRANSACTION;
    SELECT (now() - interval iDays day) INTO @dtDeleteFrom;
    SAVEPOINT PreCleanUP;
    -- Copy old records to new archive/secundary  table...
    INSERT INTO sectab (primtab_id, value1, value2, value3, datum)
    SELECT id, value1, value2, value3, datum from primtab where datum < @dtDeleteFrom;
    SELECT ROW_COUNT() INTO @iRowsCopy;

    -- Remove records from primary table...
    DELETE FROM primtab WHERE datum < @dtDeleteFrom;
    SELECT ROW_COUNT() INTO @iRowsDelete;

    -- Check if rows copied -eq rows deleted...
    IF (@iRowsCopy = @iRowsDelete) THEN
      COMMIT;
      SELECT 'Success - Committed!' AS Result, @iRowsCopy AS RowsCopy, @iRowsDelete AS RowsDelete;
    ELSE
      ROLLBACK TO PreCleanUp;
      SELECT 'Failure - ROLLBACK!' AS Result, @iRowsCopy AS RowsCopy, @iRowsDelete AS RowsDelete;
    END IF;
  END //

VBS Cleanup Sessionfiles

2009-10-14 / VisualBasic Scripting / Tim van Kooten Niekerk

Article is written in the Dutch language…

Het onderstaande script heb ik geschreven om bestanden in een bepaalde directory verwijderen als ze ouder zijn dan een opgegeven aantal dagen. Het script is ontworpen ‘silent’ te draaien m.b.v. bijvoorbeeld de windows taskscheduler-service. Het resultaat van de actie en eventuele foutmeldingen worden in de windows eventlog geregistreerd.
