SQLParameter with bulk insert.

[Pradeep]

I am having a function which accepts Database parameter array, and it
inserts to the database inside a loop.

Note:

inside the loop i am changing the values of the parameter array .

it works fine if the loop executes for only one time, but if the loop
executes more than one time i am getting the error : "field xyz is already
contained by another SqlParameterCollection"

Function abc(Parameter_Array)

begin loop

alter Parameter_Array' values

Create command object

Add parameters to the command object //i am getting
error at this point,if this is executed for the second time .

Execute

command.parameters.close();

set connection,command etc.. to null

end

Could you post actual code rather than pseudo code, what you think you are
doing might differ subtly from what you are actually doing with the code.

"bulk insert" seems to me that the command is identical, just the
parameter values change.
I think it's more efficient (and probably solves your problem) to
rewrite like this:

create command object
create parameters with dummy values, add to command
set & open connection
begin loop
change param values
execute
end loop
close connection
