I hope you know how to connect with oracle 11g in ASP.Net MVC so I am not covering this in my answer. If not then google for it. I will concentrate my answer on how to use sequece in oracle 11g for auto increment column. first create a sequence using below sample query: CREATE SEQUENCE my_sequence MINVALUE 1000 START WITH 1001 INCREMENT BY 1 NOCACHE NOCYCLE; there are 2 ways now to access the value from sequence when you want to insert it in the column: 1) using it in insert query 2) using it in trigger for 1) you can use the sequence same way as other table in your query: select my_sequence.nextval from dual; or if you want to use in insert query directly then like this: insert into mytable(auto_id column1 column2) values (sequence_staff.nextvalcol1Value col2Value) for 2) you can create a trigger and oracle will directly insert new value each time a new record is created in your table: in below code auto_id is the column in which you want to insert value from sequence. create trigger trg_mytable before insert on mytable for each row begin select my_sequence.nextval into :new.auto_id from dual; end ;
