About .sqlplan Files
SQLPLAN files are XML-based execution plan files used by Microsoft SQL Server. They store detailed data on how a query is processed.
They use the MIME type application/xml and present step-by-step instructions that the SQL engine follows for query execution.
- Main use case: Analyze and troubleshoot query performance.
- Technical details: They contain execution details like joins, indexes used, and cost estimates.
- Software support: Open them with Microsoft SQL Server Management Studio (SSMS) or any XML editor.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
How do I open a .sqlplan file?
The standard way to open a .sqlplan file is using Microsoft SQL Server Management Studio (SSMS). This software interprets the underlying XML data and displays it as a graphical execution plan flowchart, making it easier to analyze query performance.
Can I view a .sqlplan file without installing SQL Server?
Yes, you can use standalone tools like SentryOne Plan Explorer to view the graphical plan without a full SQL Server installation. Additionally, since the file format is XML-based, you can open it in any text editor (like Notepad or VS Code) to view the raw code.
What is the MIME type for .sqlplan files?
Because these files consist of structured XML data, they typically utilize the MIME type application/xml. You can learn more about how XML types function on mime-type.com.
How do I create a .sqlplan file in SSMS?
In SQL Server Management Studio, enable Include Actual Execution Plan (Ctrl+M) before running your query. Once the query finishes, right-click anywhere in the Execution Plan tab and select Save Execution Plan As... to save the file with the .sqlplan extension.
Why does my .sqlplan file look like text code when opened?
If you open the file in a generic text editor or web browser, you will see the raw XML tags and attributes rather than a diagram. To see the intended visual flowchart, you must open the file in a compatible viewer like SSMS or Azure Data Studio.
Do .sqlplan files contain sensitive information?
Yes, they can contain sensitive details such as database schema names, table structures, index names, and sometimes the actual parameter values used in the query. You should sanitize or review these files before sharing them on public forums.
Can I convert a .sqlplan file to PDF or an image?
There is no direct 'Save as Image' feature in the raw file format, but you can export the view from SSMS. To create a PDF, simply use the Print function within SSMS while viewing the plan and select 'Microsoft Print to PDF' as your printer.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
