I am using Oracle 11g for my web application. I want to add a column and a comment to an existing table. I can do that easily with the below commands
ALTER TABLE
Query to add column with comment are :
alter table table_name add( "NISFLAG" NUMBER(1,0) ) comment on column "ELIXIR"."PRD_INFO_1"."NISPRODGSTAPPL" is 'comment here' commit;
