  • Support for inline VB.Net code to create LogParser SQL queries. Write the code between <% and %> marks, it will be executed and result string will be replaced in the query. We believe this feature will be very useful for the users of Log Parser Lizard. For instance, before parsing logs you can move-copy-rename files, download from FTP, shutdown IIS, etc. You can also use .Net data types like DateTime for arithmetic operations and/or System.Envirenment settings in query parameters. This is a sample query with inline VB.Net code: <%
    'Do something here, for instance System.IO.File.Copy("c:\DailyLogs\*.log", "c:\AllLogs")
    Return ""
    date >= '<% RETURN DateTime.Today.AddDays(-7).ToString("yyyy-MM-dd")%>' -- last week

    The resulting query from this sample would be:
    SELEC TOP 100 * FROM #IISW3C# WHERE time >= #2011-10-01# -- last week
  • New "Save Query As" command to easily copy existing queries
  • New option to display exact Logparser SQL query to help debugging queries who are using in-line VB.Net, constants and snippets
