(SQL Server) Zip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to zip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.

CREATE PROCEDURE ChilkatSample

    DECLARE @hr int
    -- Important: Do not use nvarchar(max).  See the warning about using nvarchar(max).
    DECLARE @sTmp0 nvarchar(4000)
    -- This example requires the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    DECLARE @success int

    DECLARE @zip int
    -- Use "Chilkat_9_5_0.Zip" for versions of Chilkat < 10.0.0
    EXEC @hr = sp_OACreate 'Chilkat.Zip', @zip OUT
    IF @hr <> 0

    -- Initialize the zip object with the path of the .zip to be created.
    EXEC sp_OAMethod @zip, 'NewZip', @success OUT, @zipPath

    -- The MinDate and MaxDate properties use the timestamp date/time string format.
    -- Here are some examples:
    -- YYYY-MM-DD (e.g., 2024-07-31)
    -- YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)

    EXEC sp_OASetProperty @zip, 'MaxDate', '2020-12-31T23:59:59Z'

    -- You don't need to specify both MinDate and MaxDate.
    -- You can specify only one or the other if needed.

    -- The MinDate/MaxDate properties apply to all of the Chilkat methods for appending files.

    -- Recursively append to the zip object the paths of the files and directories in a directory tree.
    -- At this point we are not creating the .zip, nor are we reading the contents of the files.
    -- We are simply appending references to the files and directories in the local filesystem
    -- that will get processed when WriteZip is called.
