SQL injection from within a table - is it possible?

Is it possible to store an SQL injection string into a MSSQL database table, so when the database performs an action like through a stored proc, the SQL injection attack takes place? Not through the normal means of SQL injection via a web base means, but if you have the means of storing the data into the table directly. Example: An application has a users name in a table. Is it possible to assign the users name as the SQL injection string, something like name from table; exec master.xp_cmdshell "ping me"; -- so when the database is running a stored procedure with a select clause like select name from table it really is becomes select name from table; exec master.xp_cmdshell "ping me" ;-- from table Of course using the SQL query analyzer on the database table, all this works ok. But when I insert the SQL injection string into the table, as the name, and then query the table nothing happens. Is it possible or have I missed the point here? Thanks Peter.
