Recover not necessarily needed when take an offline-datafile online ?

Sun, 07 Sep 2008 09:27:40 GMT

Recover not necessarily needed when take an offline-datafile online ?

During my test Datafile was taken offline and online 3 times , the first two need recover before it was taken online but the last not needed. It seems the result are not consistent among 3 times.

How oracle decide whether a datafile needs recovery before taken online?

SQL> alter database datafile 17 offline;

Database altered.

SQL> alter database datafile 17 online;

alter database datafile 17 online

ERROR at line 1:

ORA-01113: file 17 needs media recovery

ORA-01110: data file 17: '/chhora/tstest1_1.dbf'

Cross/Inner join vs Left / Right outer Join

Sat, 06 Sep 2008 17:39:24 GMT

Cross/Inner join vs Left / Right outer Join

hi guys,

i am reading a very very old book on sql named

SQL fundamentals by J.Patrick

It says that.. this is how a inner join is derived

1) cross join of the tables ( cartesian product )

2) evaluate the join condition

e.g (a.id = b.id)

3) keep only the rows that evaluate to true

4) then you have your inner join table.

It also mention that 

> Join condition always evaluates to unknown f any of the join condition columns contain a null.

And the Unknown evaluations are drop.

E.G a.id = b.id

Table a

ID

-------

1

2

Table b

ID

-------

1

null

then only 

ID, ID1

-------------

1,1

is shown.

-------------------------------------------------

Now it shown an example of an left outer join

select * from table a, table b

where a.id = b.id (+);

result

ID, ID1

-------

1,1

2,NULL

Now if i follow the rules of how it is

1st) cross join / cartesia product is form 1st.

ID,ID1

-------

1,1

1,NULL

2,1

2,NULL

2nd) evaluate the condition a.id = b.id (+)...

Get sqltype of a statement

Hi all.

Do you know if there's a function that returns the "sqltype" of a statement ? 

For example, something like  DBMS_SQL.parse(cur, text,...) 

I need to parse some statements before I execute them.

Thank you.

SQL*Loader issue: merge two data fields into one table column

SQL*Loader issue: merge two data fields into one table column

Hello,

I have data to load, and TWO of the fields of the data have to be grouped into a SINGLE column of the table...
Data to load is like:

20080818,ASP,NR,73.25,USD

20080819,XYZ,ABC,12345.6,EUR



DDL of table:

CREATE TABLE mytable( dte DATE, txt VARCHAR2(10), nb NUMBER, cur VARCHAR2(4) );



expected result:

SELECT * FROM mytable;

DTE       TXT       MNT      CUR

--------- --------- -------- ---

18-AUG-08 ASP(NR)      73.25 USD

19-AUG-09 XYZ(ABC)   12345.6 EUR

i.e.: "txt" must be "field2 ( field3 )"



Trial that does not work:

LOAD DATA

INFILE *

INTO TABLE mytable

FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'

( "DTE"  DATE "YYYYMMDD"

, "TXT"  CHAR ":"\TXT\" || '(' || :\"X\" || ')'"

, "X"    FILLER

, "NB"   CHAR

, "CUR"  CHAR

)

BEGINDATA

20080818,ASP,NR,73.25,USD

20080819,XYZ,ABC,12345.6,EUR



(reason is that a "filler" field cannot be used as a bind variable)



Trial that works but the input file has to be modified (insertion of double quotes

between the two components...

Inserting into table if it doest not exists (any ways to do it in SQL )

Thu, 04 Sep 2008 17:54:04 GMT

Inserting into table if it doest not exists (any ways to do it in SQL )

hi guys,

i have a table of users with their respective subscription

Create table test

(users varchar2(10), service(varchar2(10));

Alter table test add primary key(users,service);

------------------------------------------------

A user can have many services.

Now i need to do a check among the users in the table if  they are missing a particular service.

If they are missing that service, do a insert into the table.

This is how i do it in plsql

Declare

cursor testing is select distinct user_id from test;

Begin

for testing_Rec in test loop

 begin

   select service into

   v_service 

   from test

   where user_id = testting_Rec.user_id

   and service = 'ServiceA';

 EXCEPTION

 When no_Data_found then

   insert into test values (testing_Rec.user_id, 'SERVICEA');

 end;

end loop;

end;

Is there anyway to do it in SQL alone ?

Regards,

Noob

We are doing some investigation.

I know that normally an Oracle 10 client on a pc is compatible with an Oracle Server 9i on Windowss or Unix.

We have this running , but can we forsee problems ?

Thus are there exceptions we should watch out for? For instance when using the realy thin 10.x client or otherwise.

Any experiences or ideas welcome.
