Question

I have 2 Oracle questions

1. How do I translate this SQL Server statement to work on Oracle?

    Create table MyCount(Line int identity(1,1)) 

2. What is the equivalent of SQL Servers Image type for storing pictures in an Orace database?

Answer 1

You don’t need to use triggers for this if you manage the inserts:

CREATE SEQUENCE seq;  CREATE TABLE mycount (    line NUMBER(10,0) ); 

Then, to insert a value:

INSERT INTO mycount(line) VALUES (seq.nextval); 

For images, you can use BLOBs to store any binary data or BFILE to manage more or less as a BLOB but the data is stored on file system, for instance a jpg file.
