asp.net - SQL OUTPUT Parameter Not Assigning -


i have following sql statement written in sql server 2008 isn't returning value output parameter though there data in table. added static values , ran query alone , produced record not sure if has stored procedure or vb.net code.

alter procedure  [dbo].[getgeninfo_delete01_01_22] @idx int, @fpath varchar(100) output   begin     select @fpath = filepath geninfo_e1_01_22 id = @idx       delete      geninfo_e1_01_22     id = @idx  end

my vb code

using con new sqlconnection(connstr)     using cmd new sqlcommand()         cmd.commandtype = commandtype.storedprocedure         cmd.commandtext = "getgeninfo_delete01_01_22"         cmd.parameters.add("idx", id)         cmd.parameters.add("@fpath", sqldbtype.varchar, 100)         cmd.parameters("@fpath").direction = parameterdirection.output         cmd.connection = con         con.open()         gridview1.datasource = cmd.executereader()         gridview1.databind()         con.close()     end using end using

an output parameter not show in result set. can't read executereader().

you can read like:

dim result string = cmd.parameters("@fpath").value
