C# sql proper declaration

Is it better to do this in a form:
form beginning:
 SqlCommand cmd;

then throughout the code
cmd = new sqlcommand("select * from table", Connection);

or should it be like this
Form Beginning
SqlCommand cmd = new sqlcommand();

then throughout the code
cmd.connection = connection;
cmd.commandtext = "select * from table";

Since they're functionally equivalent, I always prefer the shorter one -- doing it in one line, rather than two.  EIther is correct, though.

it depends. if you create a command object that is used several times/often, define it in the global class, and use it all over the project.
