Hallo to all,

Can someone help me?

@Barney1998 Please re-read your question and consider if anyone can understand what you're asking for based on what you wrote and without any of the context that might exists in your brain.

Please post the code you want to make dynamic, and indicate which parts of it should be dynamic.

from example ,
proc sql;
create table colour_dataset as
select t.*
from colours t
where t.colours='yellow';
quit;

I know how to use marco variable in where statement ,the question is if exist any way to use marco variable on tables onomastics i.e
%let colour = yellow;
%let colours= yellow;


proc sql;
create table &colour_dataset as
select t.*
from colours t
where t.colours='&colours';
quit;

I want give name to the table above from marco variable,videlicet i don't must to give the name yellow_dataset manual but i use one variable colour and every time i changed its name the table name changed too, for example from yellow to red.
Thanks in advance!

Two key things.

1) You are following the name of the macro variable you are trying to reference with a character that could be part of the name.  You can use a period to let the macro processor know where the name ends.

2) The macro processor ignores quoted strings that are bounded on the outside by single quotes.  Use double quotes for your strings that you want the macro processor to evaluate.

create table &colour._dataset as
  select t.*
  from colours t
  where t.colours="&colours"
;
