If you want to store documents or images in your database, you can write an application that reads the contents of the file into a variable, and supplies that variable as a value for an INSERT statement. See How to use prepared statements, and SET statement.
You can also use the xp_read_file system function to insert file contents into a table. This function is useful if you want to insert file contents from Interactive SQL, or some other environment that does not provide a full programming language.
DBA authority is required to use this function.
