如何从SQL storedprocedure调用shell应用程序？

Question

Im trying to call a notepad or calculator from a stored procedure. can anyone help?

Answer 1

For what database will this be?

For MySql you can write a UDF (User Defined Function - See http://dev.mysql.com/doc/refman/5.0/en/adding-udf.html ) to to this or use the ready made one from the UDF repository guys. See http://www.mysqludf.org/lib_mysqludf_sys/index.php . See the sys_exec function and also the section labelled 'A Note of Caution' ;-)

For Microsoft SQL see the command here: http://msdn.microsoft.com/en-us/library/aa260689%28SQL.80%29.aspx

Answer 2

maybe xp_cmdshell be useful for you.

Executes a given command string as an operating-system command shell and returns any output as rows of text. Grants nonadministrative users permissions to execute xp_cmdshell.

Answer 3

There are ways to do it in Oracle's PL/SQL as well. Google: Oracle "External Procedures" or start here:

Oracle External Procedures

You end up calling to SHELL32.DLL and telling it to open Notepad.
