east$-1.$rds$.$amazonaws.com",

return new Promise$(($resolve$,$ reject$)=>\{$

pool.query$("$DELETE FROM Items WHERE itemID$=?",[$itemID$],($error$,$ rows$)=>\{$

if $($error$)\{$ return reject$($error$)$; $\}$

if $(($rows$)$ && $($rows$.$affectedRows $==1))\{$

return resolve$($true$)$;

response $=\{$ statusCode: $400,$ error: $"$No such item" $\}$
