Help with sys_guid and Primary Keys

I am trying to use sys_guid to create unique PK_ID in my tables (see below). This works fine in oracle, but when I try to insert into a remote DB I get a precision error. Is there a way to control the length/format of sys_guid? Is there something easier to use for automaticall creating PK Id's
CREATE TABLE TEST
( PK_ID NUMBER default to_number(sys_guid(),'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX')

This works fine in oracle, but when I try to insert into a remote DB I get a precision error.What sort of "remote DB"? Oracle or non-Oracle?
Another thing occur. SYS_GUID includes some element generated by the host or the thread process - does a straightforward SYS_GUID call (i.e. without the TO_NUMBER bit) work in your set-up?
Cheers, APC

Best practices with sequences and primary keys

We have a table of system logs that has a column called created_date. We also have a UI that displays these logs ordered by created_date. Sometimes, two rows have the exact same created_date down to the millisecond and are displayed in the UI in the wrong order. The suggestion was to order by primary key instead since the application uses an oracle sequence to insert records so the order of the primary key will be chronological. I felt this may be a bad idea as a best practice since the primary key should not be used to guarantee chronological order although in this particular application's case, since it is not a multi-threaded environment, it will work so we are proceeding with it.
The value for the created_date is NOT set at the database level (as sysdate) but rather by the application when it creates the object which is persisted by Hibernate. In a multi-threaded environment, thread A could create the object and then get blocked by thread B which is able to create the object and persist it with key N after which control returns to thread A it persists it with key N+1. In this scenario thread A has an earlier timestamp but a larger key so will be ordered before thread B which is in error.
I like to think of primary keys as solely something to be used for referential purposes at the database level rather than inferring application level meaning (like the larger the key the more recent the record etc.). What do you guys think? Am I being too rigorous in my views here? Or perhaps I am even mistaken in how I interpret this?

I think the chronological order of records should be using a timestamp (i.e. "order by created_date desc" etc.)
>
Not that old MYTH again! That has been busted so many times it's hard to believe anyone still wants to try to do that.
Times are in chronological order: t1 is earlier (SYSDATE-wise) than t2 which is earlier than t3, etc.
1. at time t1 session 1 does an insert of ONE record and provides SYSDATE in the INSERT statement (or using a trigger).
2. at time t3 session 2 does an insert of ONE record and provides SYSDATE
(which now has a value LATER than the value used by session 1) in the INSERT statement.
3. at time t5 session 2 COMMITs.
4. at time t7 session 1 COMMITs.
Tell us: which row was added FIRST?
If you extract data at time t4 you won't see ANY of those rows above since none were committed.
If you extract data at time t6 you will only see session 2 rows that were committed at time t5.
For example if you extract data at 2:01pm for the period 1pm thru 1:59pm and session 1 does an INSERT at 1:55pm but does not COMMIT until 2:05pm your extract will NOT include that data.
Even worse - your next extract wll pull data for 2pm thru 2:59pm and that extract will NOT include that data either since the SYSDATE value in the rows are 1:55pm.
The crux of the problem is that the SYSDATE value stored in the row is determined BEFORE the row is committed but the only values that can be queried are the ones that exist AFTER the row is committed.
About the best you, the user (i.e. not ORACLE the superuser), can do is to
1. create the table with ROWDEPENDENCIES
2. force delayed-block cleanout prior to selecting data
3. use ORA_ROWSCN to determine the order that rows were inserted or modified
As luck would have it there is a thread discussing just that in the Database - General forum here:
ORA_ROWSCN keeps increasing without any DML

Problem with foreign and primary keys migration from SQL Server to Oracle

Hi folks, i'm using SQL Developer to migrate from a SQL Server database to Oracle and i'm stuck with a couple issues:
The worst of them so far is the fact that i can't migrate any of the PKs and FKs. After successfully capturing the SQL Server DB model and converting it to Oracle, when the tool generates the scripts, all ALTER TABLE queries that add the PKs and FKs have their target columns duplicated.
for example: when i'm trying to migrate a simple table that contains an Id (PK) and Name columns, the tool generates the following scripts:
PROMPT Creating Table TestTable...
CREATE TABLE TestTable (
Id NUMBER(10,0) NOT NULL,
Name VARCHAR2 NOT NULL
PROMPT Creating Primary Key Constraint PK_TestTable on table TestTable ...
ALTER TABLE TestTable
ADD CONSTRAINT PK_TestTable PRIMARY KEY
Id,
Id
ENABLE
As for the FKs, the tool duplicates the columns as well:
ALTER TABLE SomeTable
ADD CONSTRAINT FK_SomeTable_SomeTable2 FOREIGN KEY
SomeTable2Id,
SomeTable2Id
REFERENCES SomeTable2
Id,
Id
ENABLE
Does anyone have a clue on how to solve these issues? I'd be greatly thankful for any answers!

Hi Fernando,
I was unable to replicate this issue. My primary / foreign keys where defined using unique columns.
PROMPT Creating Primary Key Constraint PK_Suppliers on table Suppliers ...
ALTER TABLE Suppliers
ADD CONSTRAINT PK_Suppliers PRIMARY KEY
SupplierID
ENABLE
I tried a few things like
capturing twice and renaming both models the same
renaming the converted models
but with no luck.
I think this issue is occuring either at the capture or convert phase.
1) Are you performing the capture online or offline?
2) Can you provide a the entire DDL for one of these tables and its indexes to see if I can replicate?
3) Did the capture or convert fail or have to be redone at any stage ?
I all else fails I would attempt a capture and convert again using a brand new repository (create a new schema in Oracle and associate the migration repository with it).

Dynamic SQL Joining between tables and Primary keys being configured within master tables

Team , Thanks for your help in advance !
I'm looking out to code a dynamic SQL which should refer Master tables for table names and Primary keys and then Join for insertion into target tables .
EG:
INSERT INTO HUB.dbo.lp_order
SELECT *
FROM del.dbo.lp_order t1
where not exists ( select *
from hub.dbo.lp_order tw
where t1.order_id = t2.order_id )
SET @rows = @@ROWCOUNT
PRINT 'Table: lp_order; Inserted Records: '+ Cast(@rows AS VARCHAR)
-- Please note Databse names are going to remain the same but table names and join conditions on keys
-- should vary for each table(s) being configured in master tables
Sample of Master configuration tables with table info and PK Info :
Table Info
Table_info_ID   Table_Name
1       lp_order
7       lp__transition_record
Table_PK_Info
Table_PK_Info_ID   Table_info_ID   PK_Column_Name
2               1   order_id
8               7   transition_record_id
There can be more than one join condition for each table
Thanks you !
Rajkumar Yelugu

Hi Rajkumar,
It is glad to hear that you figured the question out by yourself.
There's a flaw with your while loop in your sample code, just in case you hadn't noticed that, please see below.
--In this case, it goes to infinite loop
DECLARE @T TABLE(ID INT)
INSERT INTO @T VALUES(1),(3),(2)
DECLARE @ID INT
SELECT @ID = MIN(ID) FROM @T
WHILE @ID IS NOT NULL
PRINT @ID
SELECT @ID =ID FROM @T WHERE ID > @ID
So a cursor would be the appropriate option in your case, please reference below.
DECLARE @Table_Info TABLE
Table_info_ID INT,
Table_Name VARCHAR(99)
INSERT INTO @Table_Info VALUES(1,'lp_order'),(7,'lp__transition_record');
DECLARE @Table_PK_Info TABLE
Table_PK_Info_ID INT,
Table_info_ID INT,
PK_Column_Name VARCHAR(99)
INSERT INTO @Table_PK_Info VALUES(2,1,'order_id'),(8,7,'transition_record_id'),(3,1,'order_id2')
DECLARE @SQL NVarchar(MAX),
@ID INT,
@Table_Name VARCHAR(20),
@whereCondition VARCHAR(99)
DECLARE cur_Tabel_Info CURSOR
FOR SELECT Table_info_ID,Table_Name FROM @Table_Info
OPEN cur_Tabel_Info
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @whereCondition =ISNULL(@whereCondition+' AND ','') +'t1.'+PK_Column_Name+'='+'t2.'+PK_Column_Name FROM @Table_PK_Info WHERE Table_info_ID=@ID
SET @SQL = 'INSERT INTO hub.dbo.'+@Table_Name+'
SELECT * FROM del.dbo.'+@Table_Name+' AS T1
WHERE NOT EXISTS (
SELECT *
FROM hub.dbo.'+@Table_Name+' AS T2
WHERE '+@whereCondition+')'
SELECT @SQL
--EXEC(@SQL)
SET @whereCondition = NULL
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
END
Supposing you had noticed and fixed the flaw, your answer sharing is always welcome.
If you have any question, feel free to let me know.

BC4J Custom API: Batch Validation with Sequence-based primary key

Hi people,
I am trying to create a BC4J Custom API using the Batch Validation feature of iSetup Framework. However, my entity object has a sequence-based primary key, and this key is carried to the View Object. This way, i have three attributes marked as key attributes in the VO: InvoiceTypeId (the sequence), OrganizationId and InvoiceTypeCode (The alternate, developer key). the primary key is marked AZ_EXPORTABLE=FALSE, because it must be rebuilt in the target using the alternate key.
I was able to successfully extract a single row to XML using this API (i am testing locally). When i try to import this XML file containing a single row, i get the following exception. Is this feature supported in Batch Validation mode?
Regards
Thiago Souza

Hi Thiago,
I would suggest to test your API first with row by row validation mode where you would be resolving the foreign and primary keys as specified in the framework. This would help you to understand the framework better and once it starts working for you and then you can try with batch validation mode.
Thanks
Mugunthan.

Table and Primary Key Case Sensitive in Automated Row Fetch

Why are the table and primary key fields case sensitive in the Automated Row Fetch process? I'm debugging an error in this process and I'm not sure what the case should be.

Russ - It's a defect of sorts. Use upper case in the process definition. I don't think these processes will work with tables or columns whose names are not known to the database as upper-case values, i.e., defined using double-quoted non-upper case.

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C
SAVING THE LIST DATA TO DB
DATA: L_WA(800).
LOOP AT T_TAB into L_WA.
ZDBTAB-DATALEN = STRLEN( L_WA ).
MOVE: L_WA to ZDBTAB-RAWDATA.
ZDBTAB-LINENUM = SY-TABIX.
INSERT ZDBTAB.
READING THE DATA FROM DB
DATA: BEGIN OF T_DATA,
             SEQNR type ZDBTAB-LINENUM,
             DATA type ZDBTAB-RAWDATA,
           END OF T_TAB.
Select the data.
SELECT linenum rawdata from ZDBTAB into table T_DATA
     WHERE repid = w_repname
     AND rundate = w_rundate
     ORDER BY linenum.
Populate calling Internal Table.
LOOP AT T-DATA.
APPEND T_DATA to T_TAB.
ENDLOOP.

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Help with count and sum query

Hi I am using oracle 10g. Trying to aggregate duplicate count records. I have so far:
SELECT 'ST' LEDGER,
CASE
WHEN c.Category = 'E' THEN 'Headcount Exempt'
ELSE 'Headcount Non-Exempt'
END
ACCOUNTS,
CASE WHEN a.COMPANY = 'ZEE' THEN 'OH' ELSE 'NA' END MARKET,
'MARCH_12' AS PERIOD,
COUNT (a.empl_id) head_count
FROM essbase.employee_pubinfo a
LEFT OUTER JOIN MMS_DIST_COPY b
ON a.cost_ctr = TRIM (b.bu)
INNER JOIN MMS_GL_PAY_GROUPS c
ON a.pay_group = c.group_code
WHERE a.employee_status IN ('A', 'L', 'P', 'S')
AND FISCAL_YEAR = '2012'
AND FISCAL_MONTH = 'MARCH'
GROUP BY a.company,
b.district,
a.cost_ctr,
c.category,
a.fiscal_month,
a.fiscal_year;
which gives me same rows with different head_counts. I am trying to combine the same rows as a total (one record). Do I use a subquery?

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
user610131 wrote:

I am trying to combine the same rows as a total (one record). Do I use a subquery?Maybe. It's more likely that you need a different GROUP BY clause, since the GROUP BY clause determines how many rows of output there will be. I'll be able to say more after you post the sample data, results, and explanation.
You may want both a sub-query and a different GROUP BY clause. For example:
WITH    got_group_by_columns     AS
     SELECT a.empl_id
     ,     CASE
                    WHEN c.category = 'E'
              THEN 'Headcount Exempt'
                    ELSE 'Headcount Non-Exempt'
            END          AS accounts
     ,      CASE
                    WHEN a.company = 'ZEE'
                    THEN 'OH'
                    ELSE 'NA'
            END          AS market
     FROM              essbase.employee_pubinfo a
     LEFT OUTER JOIN mms_dist_copy             b ON   a.cost_ctr     = TRIM (b.bu)
     INNER JOIN       mms_gl_pay_groups        c ON   a.pay_group      = c.group_code
     WHERE     a.employee_status     IN ('A', 'L', 'P', 'S')
     AND        fiscal_year           = '2012'
     AND        fiscal_month          = 'MARCH'
SELECT    'ST'               AS ledger
,       accounts
,       market
,       'MARCH_12'          AS period
,       COUNT (empl_id)      AS head_count
FROM       got_group_by_columns
GROUP BY accounts
,            market
;But that's just a wild guess.
You said you wanted "Help with count and sum". I see the COUNT, but what do you want with SUM? No doubt this will be clearer after you post the sample data and results.

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
[[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
volume controls issues are windows, not firefox.

CMP with auto-increment primary key.Please help

Hi all,
I new with EJB technology so please bear with me.
Env: 2k Server, SQL 2k Server
Sun One(Forte EE) to develop and deploy CMP
I got the servlet to load the data from CMP's business mehods
is fine. Calling the findPrimaryKey is OK too. Even when I try to insert the row into DB is OK. At this time I make key PK is int AND NOT
AUTO INCREMENT everything is OK. In the ejbCreate method
I called setPK, setName ...It's fine.
The problem comes when I try to make the PK(still int) to be auto-increment field.In ejbCreate not call setPK because of in SunOne IDE, under the J2EE RI tab of EJB Module property, the Auto generate SQL I set to false so that I can
modify the SQL statement under SQL Deployment.createRow not taking the PK. I thought that will do it but it doesnot like it at all (I got Exception with transaction rollback)I just want to insert a single row with ID and name that's all.
Then I changed the SQL statment take PK and changed the Auto Generate SQL to True and in ejbCreate the PK as one of the args and called setPK this time with null object. It doesn't like neither.(Exception Cannot set the primary key with null. That is reasonable.)
I thought using EJB fast and clean technique would help developer to develop application with easiness.
So I realy stuck with this, I wonder ejb 2.0 support for auto increment at all because I would like to take advantage of the auto increment feature of the DB without writing the PrimaryKeySequence generator at all.
Am I missing something with this? May be just config thing to tell
that my PK is auto-increment field so that when the ejbCreate called it knows not taking the PK or even not asking to call setPK in ejbCreate.
Any help would appreciated.

Problem with type conversion and primary key during row fetch

[Note, this error occurs in Oracle XE, APEX 2.1.0.00.39]
I have been having a problem with Automatic Row Fetch:
ORA-01460: unimplemented or unreasonable conversion requested
So in an effort to resolve this, I created a PL/SQL process with the query below and was able to isolate the same error. The problem seems to come from one of the primary keys being a "number" type (APP_ID). The error occurs on the line:
where u.app_id=:P5_APP_ID
I have tried the following variations on this line in an effort to resolve this, but all generate the same error:
1) where to_char(u.app_id) = :P5_APP_ID
2) where u.app_id = to_number(:P5_APP_ID)
3) where to_char(u.app_id) = to_char(:P5_APP_ID)
I've also tried the laternate syntax "&__." and "#__#", but these don't function in the Source field and show up as syntax errors.
Any suggestions are welcome.
begin

select app_name, apptype, appcreator, appurl
from application_users u, application_info i

I found a prior post referencing a similar issue and it was solved by using the "v(__)" syntax. This did resolve my issue, however, I have a quick follow-on which I'm hoping someone can answer quickly...
Since the "v(__)" syntax won't work for the Automatic Row Fetch (at least to the best of my knowledge), I have to do a manual process. However, the manual query as shown above doesn't actually populate any of the form values through the bind variables. They all remain at their cached values from prior data entry on the form.
Is using the bind variables for assignment incorrect, or is there something that must be done to get the updates to show up in the form (ordering of processes, etc.).
My manual process is running in the Load: Before Header state so I would have expected it to update all of the fields.
Thanks in advance,
Barney

Problems with database modelling and primary keys

Hi,
I use JDeveloper exclusively for data modelling and generating the sql to build my db.
Its good but i have found a bug that can be rather annoying:
If i change the primary key of a table, the change does not seem to register within the model. So when i try and create a foreign key relationship to another table, the type is of the old type (say i went from varchar2 to number).
The only way around this is to delete the table and create it again. This also causes problems because the db generation wizard will then refuse to open properly (because it does not know that a table has been deleted).
Is this a known issue?
Cheers
Rakesh

Is this forum meant for reporting bugs or not? This issue i have stated is repeatable and in the current version.
