sql - Create function in MonetDB -

i'm trying add simple function in monetdb @ database level, sum(n) , returns result

create function sys.foo(number int) returns int begin declare tsum int; set tsum = 0; while number > 0 set tsum = tsum + number; set number = number -1; end while; return tsum; end; 

while attempting execute above code i'm seeing error follows

[error code: 0, sql state: 42000] syntax error, unexpected $end, expecting while: end of input stream in "create function sys.foo(number int)

i add same function in mysql, , works!!

>select sys.foo(10)  sys.foo(10) ----------- 55
