Hi,
I have one dataset called Cust_demo whci saved all the customer demographic information such as Cust_name, cust_Address and zip code..etc.. Now initially we have defined address variable as a character with length 8, now since the length of address field started increasing we have to make some more space for address variable suppose 10, so can i change this length of address variable?
Also this dataset is quite big almost18-20 gb so i can't take risk to recreate it with new length so any Efficient way without creating new dataset appreciated.
Regards,
Tushar Jagtap.

proc sql;
alter table have
modify colname char(xxx) format=$xxx.;
quit;
