Re: SQL Select statement

Hi Chris,

1) Any other method if I don't want to use OR ?
2) The version I am using is Oracle 7. It will be upgraded to Oracle 9i
soon.
3) Where to get the pdf version of the book?

Thanks.

Best Regards,

Hi,

1, Use "or" >>>
      select * from emp where ( ename like 'SMI%' OR ename is null )

2, this works fine in Oracle 8.1.7
       select d.*,(select sum(sal) from emp e where e.deptno = d.deptno)
from dept d;
what version are you using ?
3, There are many good books on the market but the one i couldn't do
without is
      Oracle 8i complete reference by Kevin loney and George Koch
      get the one with the pdf version of the book on cd because it saves a
heck of a lot of searching time.

Regards
Chris Farmer

Hi,

I am new to Oracle database. There are a few things that I need help.

1) As we know, the LIKE operator in SQL statement will not return the field
which is NULL.
    So, what can we do in order for the field which is NULL to be return?

2) In SQL Server, it is possible to select a column using another SQL
statement.
     Eg. select abc, (select sum(def) from B), ......
     I tested using Oracle SQLPlus, and keep getting the error message
missing expression.
     How to accomplish this in Oracle?

3) What is the best reference to look for to get started with Oracle
database?
     Eg, how do we know what features are available in Oracle and how to
use it (syntax).

Thank you in advance for the help.

Best Regards,
