    Can't be done directly from t-sql. You need to invoke the command line using xp_cmdshell. There are plenty of zip tools around which provide a CLI and give you their syntax.

    If you're using a job you could do this using powershell as an alternative to the standard command line.

    A final alternative, you could write your own CLR function for SQL Server.

    Do what I'd do, and type "xp_cmdshell" into your favourite search engine. If you're not familiar with the command line syntax of whatever zip utility you're using, you'll need to look that up as well. Post back if you get stuck on anything in particular.

    There are lots of examples right here on the site. Just do a search for xp_cmdshell and zip.

    Here's one example here. And another. And one more[/url]. There are still others to be found.

    I just published an article (https://www.sqlservercentral.com/articles/unzipping-word-documents-in-tsql) that explains how to natively unzip in T-SQL
