Still MySQL founder Monty Widenius wants to have Russia and China reject the deal to save the future of MySQL… This will delay the deals further. Good for IBM, bad for Oracle !

I posted last year about 1!=1

Today I realized this could be solved with the scale

SQL> drop table lsc_t
Table dropped.
SQL> create table lsc_t(x number, y number(*,6))
Table created.
SQL> insert into lsc_t values (1/3*3,1/3*3)
1 row created.
SQL> commit
Commit complete.
SQL> select * from lsc_t where x=1
no rows selected.
SQL> select * from lsc_t where y=1

         X          Y
---------- ----------
1.00000000          1

So if you have amounts in US$ or GB£ or CHF, do not use NUMBER, use NUMBER(*,6) or NUMBER(*,2) or whatever is relevant to your business!

Ok, the last hint from my dba regarding Oracle Support :

If flash really drives you nuts, go for html : supporthtml.oracle.com

Still Oracle is suffering with European Union Commission who is still blocking the Sun deal.

google news about the deal

Sometimes the issues I submit are a bit exotic but there it was a join with one view using one function and dual returning wrong results. Reproducible at will on any db 10.2.0.4 and below.

After 2 weeks the helpful engineer told me it is fixed with patch 6471020 and in 11g. I asked if he tried it but he said no. As the patch is not available on my platform I asked if could try it but then he came back with an amazing workaround he became from an ARE (advanced resolution engineer) :

Remove the function from the view.

Unreal

let’s check one, briefly :

*** ASSERT at file pdw4.c, line 2080; Type 0xffffffff7d79fb40 has no MAP method.
Source Location = _anon__3d2474b28__AB[1, 7]

== Dump of OPT Context Object ffffffff7c519ec8. ==

...

It is a kind of dump file, apparently. I could not find details on metalink. I generate the one above in 10.2.0.4 sparc with the following code

create or replace type t1 as object (x number)
/
create or replace type t2 as table of t1
/
exec if t1(1)member of t2()then null;end if

Dates will change, keep an eye on the schedule, and do not base your business on expected dates ! Please be patient

import java.sql.*;
public class HelloWorld {
  public  static void main(String[] args) throws SQLException {
    DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
    ResultSet res = DriverManager.
      getConnection("jdbc:oracle:thin:@srv1:1521:DB01", "scott", "tiger").
      prepareCall("select 'Hello World' txt from dual").
      executeQuery();
    res.next();
    System.out.println(res.getString("TXT"));
  }
}

let’s compile
javac -classpath $ORACLE_HOME/jdbc/lib/classes12.jar HelloWorld.java

and run

$ java -classpath $ORACLE_HOME/jdbc/lib/classes12.jar:. HelloWorld
Hello World

that’s all folks!

But no more patchset. This the first time I see a release with only 1 pachset.

Well, if you use Linux, you can go to 11gR2. Otherwise you may better stick to 10.2.0.4 for a few more months

Ref: 742060.1
11.1.0.7 is the last patch set for Release 11.1
