Which MIME types are related to file extension ".sql"?
The .sql file extension is associated with 4 MIME types:
text/x-sql, text/x-plsql, text/x-tsql, application/sql.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .sql Files
SQL files are plain text files that hold Structured Query Language commands used for managing databases.
They come in various MIME types such as text/x-sql, text/x-plsql, text/x-tsql, and application/sql.
Each MIME type reflects a different SQL dialect:
- text/x-sql – standard SQL commands
- text/x-plsql – Oracle’s PL/SQL commands
- text/x-tsql – Microsoft’s Transact-SQL code
- application/sql – general SQL script files
They are executed by database engines like MySQL, PostgreSQL, Oracle, or Microsoft SQL Server.
You can view and edit them with text editors such as Notepad, Notepad++, VS Code, or specialized database tools like MySQL Workbench and SQL Server Management Studio.
According to FilExt.com, these files play a key role in developing and maintaining database structures and operations.
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 and view an SQL file?
Because .sql files are plain text, you can open them with any basic text editor like Notepad (Windows) or TextEdit (macOS). For easier reading and syntax highlighting, developers prefer code editors like Visual Studio Code, Sublime Text, or Notepad++.
How do I run or execute an SQL file?
You cannot "run" an SQL file like a program; it must be executed by a database management system. You generally import the file using tools like MySQL Workbench, phpMyAdmin, or SQL Server Management Studio (SSMS) to apply the commands to your database.
Can I convert an SQL file to Excel or CSV?
Not directly, because an SQL file contains code instructions (like CREATE TABLE or INSERT), not a spreadsheet. To get the data into Excel, you usually execute the SQL script in a database first, and then export the resulting table data to CSV or XLSX format.
What is the correct MIME type for SQL files?
There is no single standard, but application/sql is commonly used for generic scripts. Depending on the specific database dialect, you might encounter text/x-sql for standard SQL, text/x-tsql for Microsoft Transact-SQL, or text/x-plsql for Oracle databases.
Are SQL files dangerous to open?
Opening an SQL file in a text editor is safe because it is just text. However, executing an unknown SQL file against your database can be dangerous, as it may contain malicious commands designed to delete data (DROP) or steal information.
Why does my SQL file look like random symbols?
If the file appears unreadable, it might be a binary database dump or a compressed file (e.g., .sql.gz or .sql.zip) that was renamed. Verify the file source; standard SQL files should always be human-readable text.
How do I create an SQL file?
You can create one using any text editor. Simply write your database queries (e.g., SELECT * FROM table;) and save the file with the .sql extension. Ensure you select "All Files" in the save dialog so the editor doesn't append .txt to the end.
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.
