Question about Alter table syntax
Hi all,
I have an issue I need help with. I have created a script for an automated partition create on a monthly basis. It creates a monthly partition containing all dates within the respective month. The script is essentially this:
ALTER TABLE SCHEMA.TABLE
ADD PARTITION &&1
VALUES LESS THAN (to_number(to_char(to_date('&&2', 'DD-MON-YY'), 'YYYYMMDD')))
TABLESPACE LARGE_DATA94 COMPRESS;
I continually get this error message "ORA-14019: partition bound element must be one of: string, datetime or interval literal, number, or MAXVALUE"
The variable &&2 is passing in character data for the first of the month (E.G. '01-SEP-12'). &&1 passes character data for the month in MONYY ('AUG12') I can run this query:
select
(to_number(to_char(to_date('&&2', 'DD-MON-YY'), 'YYYYMMDD')))
from dual;
With the output of 20120901. I cannot understand why I am able to run this partition create statement by hardcoding 20120901 but passing it in as a variable I receive the error. Note that I am not having problems with the &&1 variable. If anyone has any ideas please let me know. Thanks!

Thanks!I don't understand why you are taking a string, converting it to a date, then converting the date BACK TO a string ... then trying to convert that string to a number.
What is the data type of the partitioning key? It appears that it is a NUMBER, but actually represents a DATE. If so, that is a fundamentally flawed design.

Hello Gurus,
I have a question about "update table" entries. I read somewhere that an entry in update table is done at the time of the OLTP transaction. Is this correct? If so, does this happen on a V1 update or V2 update? Please clarify. Similarly, an entry in the "extraction queue" (incase you are using "queued delta" will happen on V1 update. I just want to get a clarification on both these methods. Any help in this matter is highly appreciated.
Thanks,
SreekanthHi
update tables are temporary table that are refreshed by v3 job.update table is like buffer, it gets filled after updation of application table and statistical table through v1 v2 update . we can bypass this process by delta methods.

Question about WebLogic query syntax
Hello,
I am using WebLogic Server 6.0, which came as part of the WebGain
Studio SE 4.5 development kit. My question regards the Web Logic query
syntax, which I have not yet mastered.
I am trying to create a finder method that takes a single argument
of type "char" and finds all matching fields of the column "keyword" in
which the argument is the first letter of keyword. That is, if I were
only looking for fields beginning with the letter "M", I'd use:
(like keyword 'M%')
However, I'm looking for all fields beginning with the first letter
defined by the first argument. Sadly, this syntax:
(like keyword '$0%')
doesn't seem to be working. Any suggestions on the correct syntax?
If this is not the right forum for this question, could someone
suggest an appropriate newsgroup?

Question about multiple table JOIN syntax
Good morning,
I'm trying to join three tables and getting an error. Here is the query:
with
p (messageid, parentmessageid, subject) as
select 2001, null, 'xyz' from dual union all
select 2002, 2001, 'ngh' from dual union all
select 2003, 2001, 'nghj' from dual union all
select 2004, 2001, 'pppp' from dual union all
select 2005, null, 'hhhhh' from dual union all
select 2006, 2005, 'hhhhj' from dual
m (thread, messageid) as
select 1004, 2001 from dual union all
select 1005, 2006 from dual
select p2.messageid, p2.parentmessageid, p2.subject
from (p p2 left outer join m m2
on (p2.parentmessageid = m2.messageid))
join m m3
on m3.messageid = p2.messageid
; which gives an "ORA-00918: column ambiguously defined.
I can't figure out why it gives that error. I fail to see the ambiguity.
Thank you for helping,
John.
P.S: In case someone wants to get a good laugh, here is a "solution" that does not have any ambiguity:
with
parentchild (messageid, parentmessageid, subject) as
select 2001, null, 'xyz' from dual union all
select 2002, 2001, 'ngh' from dual union all
select 2003, 2001, 'nghj' from dual union all
select 2004, 2001, 'pppp' from dual union all
select 2005, null, 'hhhhh' from dual union all
select 2006, 2005, 'hhhhj' from dual
messagethread (thread, messageid) as
select 1004, 2001 from dual union all
select 1005, 2006 from dual
j1 as
select p.messageid, p.parentmessageid, p.subject, m.thread
from parentchild p
left outer join messagethread m
on p.parentmessageid = m.messageid
j2 as
select j1.messageid, j1.parentmessageid, j1.subject, j1.thread, m.thread t2
from j1 left join messagethread m
on j1.messageid = m.messageid
select j2.messageid, j2.parentmessageid, j2.subject, nvl(j2.thread, t2)

John.I tried NO_QUERY_TRANSFORMATION and MATERIALIZE but the error still was there. So it might not be a problem of rewriting the query.
However I checked the explain plan for a similiar query which is working.

SSMA (Access - SQL 2012) newbie question about new tables
I have successfully run SSMA and moved the back end tables of an Access project to SQL Express 2012.
Some questions:
- if I add a new table to the SQL backend, how do I get it to appear in the Access project?
- if I want to move the whole thing to another computer, how do I go about it?
- do I always have to have the SSMA app installed?
- I can't see an ODBC datasource on the machine
Thanks for some help
CarolChiThanks, I was not clear in my questions:
1. Given that from now on the tables should all be in SQL, I think it would be better to create new tables in SQL them there rather than create them in Access and have to keep moving them to SQL with SSMA. So if I create a new table in SQL how can I
see it in Access? Or can I easily create a linked table in Access?
The table created by SSMA have this property:
If I create a new table in SQL and link it I get a more classic ODBC connection:
2. I am happy with SQL backup/restore, attach/detach. But how does Access know where the SQL Database has gone?
3. I thought the migration was a one time task, but from what you say it is an ongoing "linking" app. So I would be better to export my tables and re-link them to get something that can be moved to another network or computer?
4. The SSMA looks very much like an ODBC connection.
This is a new project so I will have to make lots of new tables and also move the whole thing around to different computers, on different networks.

Question about multiple tables and formulas in numbers
I was wondering about having a formula that effects one table based on data in the other table. I have a spreedsheet that i created for work. In column A is a list of addresses. In column B-ZZ is a list of "billing codes" the get applied to the service work done for that address.Its kind of difficult to look at this large spreadsheet on my iphone and edit it on the go. Is there a way to, Have another column, possibly on sheet 2 or something, where i type in these "billing codes" and they would fill an x or some other character in cell that corrisponds with that billing code on that address line? So to be as plain as possible, I want to enter data in one cell (another sheet if possible) and have it "mark" another cell in response to the specific data on that "entry cell." Im thinking this way because instead of scrolling back and fourth on the sheet on my iphone, to "mark" the boxes, i could just navigate to sheet 2 enter the data, or "billing codes" and they would "X" the cell that would match up with the code column and address row. each address row would have a seperate "entry field" in sheet 2, to make the formula easier. thanks for any help
Tom,
That's a lot of columns for jsut a table of marks that reflect an input. Sure, you could have each cell in that giant table check to see if some corresponding cell contains certain text, but that document is going to be slower than you might be able to tolerate.

Question about selection table analysis
Dear All,
My last post was closed by the moderator so I would like to ask a different question. Please apologize if my question is trivial.
1. There is a selection table seltab with one fields of type I, with the following contents:
I GT 3 0
I NE 8 0
The literature eg. ABAP Objects says that the control statement like IF or CASE can be used with logical expression IN.
Now I am checking if the variable test fulfills the conditions defined by the selection table.
DO 10 TIMES.
IF test IN seltab.
write test.
ENDIF
test = test + 1.
ENDDO.
As a result I get a full list of values.
1 2 3 4 5 6 7 8 9 10
2. Now, if the table contains
I GT 3 0
I get
4 5 6 7 8 10 as expected
3. If the table seltab contains
I NE 3 0
the result also seems to be ok
1 2 4 5 6 7 8 9 10
The final question is. Is it true that the logical expression IN cannot be used with IF for more complex data comparisions?
Thanks,
GrzegorzWell, the contents
I GT 3 0
I NE 8 0
I read as:
the variable fulfills the condition if is greater than 3 and not equal 8
test > 3 and
test <> 8
which should give the result from the example above a list
4 5 6 7 9 10
What is wrong with my analysis?
Regards,
Grzegorz -
hi gurus,
i need to find a relation between profit center and G/L account to do same reporting on charges by profit centers.
in table GLPCA i have the fields i need, but i have a question: are all the charges traced in this table (GLPCA) ? in other words are all the vendors invoices present in this table.
Thank you.Only for those entries in which profit center is assigned.
Eg :Say expenses or revenue for which profit center is assigned directly. only the expenses line item(i.e Dr) or revenue line item (i.e CR) alone will be there in GLPCA.
But in BSEG you can find both the entries(Dr & Cr) for the same doc, which you cant find in GLPCA.
Hope you understood.

Question about temporary tables and imports.
Hello everybody.
Interesting one this. We have an application that uses global temporary tables. We refresh live to test using import of the application schema. I noticed when doing this yesterday that the temporary tables were being recreated in test as perminant rather than temporary.
Is there a reason for this? Has anyone come across this before? Is there a way around it (apart from manual checking)?
Many thanks

Question about ALTER TABLESPACE add/drop datafile
Good afternoon,
As an exercise, I created a tablespace STORETABS and added a datafile to it using the command:
SQL> alter tablespace storetabs add datafile 'e:/storetabs3.dbf' size 50M;This step succeeded. A new file was created in the root of e: as expected.
Following that command, I issued:
SQL> alter tablespace storetabs drop datafile 'e:/storetabs3.dbf';
Tablespace altered.The command succeeded. However, the file *'e:/storetabs3.dbf'* was not removed. After re-reading the documentation found at http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_3002.htm, I get the impression that removing the O/S file itself is something that always needs to be done manually.
The question: Am I correct that there is no option to cause the "alter tablespace <tablespace> drop datafile <datafilename>" to delete the O/S file ? In other words, must the O/S file always be manually deleted as a separate step ?
Thank you for your help,
John.I believe in windows directory paths used backslash and not forward slash.
You can argue why oracle does not give error, either while creating or while dropping ;)

Harry.hi Harry
I'm not sure what your question is, but the af:table component in the SRList.jspx page of the SRDemoSample application uses "paging".

I want to create a table and am using sql8 as back end.
My front end is Access. I want to create a button in the access form that will update certain values in a table in the database. I dont want to add the database in the access form.
I am thinking of creating a linked table getting values from the main table and create a linked table from it. Then i was thinking of updating the linked table by adding it up to the access form and using a button for the update query.
Would it work.
What wud be the syntax to create a linked table from the main one and wud the updates show on the main table if i update the linked table.
Is there an alternative to it.
I do not want to use any triggers though.

update tables are temporary table that are refreshed by v3 job.update table is like buffer, it gets filled after updation of application table and statistical table through v1 v2 update . we can bypass this process by delta methods.

Simple beginner question about default tables (LOGMNR, etc.)
Hi all, I just installed SQL Developer and the Express server. I have worked with other SQL databases and with remote Oracle databases. But never been a DBA for an Oracle DB. I tried searching on LOGMNR and AQ$_, but couldn't find anything, hence this question.
If there is some online documentation that covers these particular tables and my question, then a pointer to that would be appreciated.
Anyway, I created a connection per the instructions and it seemed to work. But when I look at tables listview, I see a whole slew of tables. I assume these are all housekeeping/meta data tables (eg. information_schema in MySQL). Is this correct?
Also, short of manually creating a filter for each of the file types ("%$%"help", "LOGMNR%", "SQLPLUS%", etc.), is there an easy way to ignore these tables and just see the tables I want to create for testing purposes?
And I am curios why these all show up by default. Could it be that I am expecting something because of experience with other databases and am actually doing things the "wrong" way? Or is this just because I am using the Express Server? Or is there another (very good) reason for these tables to exist?
Thanks,
justmeThe complete oracle documentation is at http://tahiti.oracle.com. There is a lot of it, but Log Miner and Advanced Queuing have their own manuals. You should also consider starting with the Concepts Manual followed by one of the "2-day" tutorials such as "2-Day DBA"
What user are you connecting as? It sounds as if you are connecting as SYS or SYSTEM if you can see the dictionary tables.
You should create a separate user to connect as.
