Hi thanks for answer, but didn't help. Got this error instead :

Error: cannot implicitly convert expression "UPDATE guirequest 
SET done_request = SYSDATE() WHERE request_id=" ~ 
cast(const(char)[])hash[cast(uint)i] ~ ";" of type char[] to 
string


Notice you use auto x .... Am I better of using something like

auto sql_respons ="UPDATE guirequest SET done_request = SYSDATE() 
WHERE request_id=" ~ hash[i] ~ ";";
