How to validate for a unique constraint?

Hi all,
Below is my stored procedure that updates the well name from the VIEW_TABLE1 into the WELL_HEADER_TABLE after comparing the apinumbers present in both the tables .
I need to put a condition in which the apinumber should be checked and validated to be a unique value in my first comparision .Only the well names corresponding to the unique values of api_number should be updated .
so can any one suggest me what chages do i need to implement in my code to perform this vaidation.pls help me in resolving this issue....
Thanks and Regards

Hi Sam /Dan ,
But in my requirement i need to compare the first 10 digits of the api number so i have made use of substring .No problem Dan seems to be prettybit angry on the way my code looks :-) .....
Well this unique key is no more a problem .Its resolved as no duplicate values will be present in the apinumber.Now the only challenge infront of me is that i need to validate api number .In case the apiNumber of the view table is greater or less than 10 the well names needs to be updated and rows needs to be inserted into the well header table.
I have done this part but something is going wrong and its not working .i mean even api number less than 10 are getting inserted and updated .so can u suggest me what changes i need to make
[\n]
on (SUBSTR(WORKFLOW.VIEW_TABLE1.API_NUMBER,0,10) = SUBSTR(WORKFLOW.Well_Header_Table.API_NUMBER,0,10) AND count(WORKFLOW.VIEW_TABLE1.API_NUMBER >= 10) )
[n]
Just check whether this condition will work...

How to validate for non-english character on a single line text field

In a "Single Line Text" field we would like to allow the users to enter alpha numeric values only. We should show error when the user enter non-English values like
carácter
Vijayaragavan, MCTS

Hi,
According to your post, my understanding is that you wanted to validate for non-english character on a single line text field.
I recommend to use jQuery to attach regular expression validation. Please refer to:
Using #jQuery to attach regular expression validation to a #SharePoint list form field
In addition, for custom validations you can create your own Types. Refer to
this[^] for creating custom field type

Help needed for PK_REV_COL unique constraint violation

We’re receiving a SNPW.PK_REV_COL unique constraint violation when trying to reverse a pipe delimited source file. There are no duplicate column names within the source file but the same column names are used across several different input files. Does anyone have a solution to this problem?

Hi,
This is a problem with the Reversed tables from ODI.
Go to work repository and truncate any "snp_rev...." tables.
That should solves it.

How to validate for proper date format

Hi Experts,
I am using following Fm to calculate date difference.....
call function 'FIMA_DAYS_AND_MONTHS_AND_YEARS'
      exporting
        i_date_from = wa_draw-zdm_vld_to_dat
        i_date_to   = sy-datum
      importing
        e_days      = v_days.
    if sy-subrc = 0 .
      if v_days > 0.
But value of field zdm_vld_to_dat (data type DATS , YYYYMMDD)   in database tables itself is wrong   ...like ct/-0/29-o
I want to avoid passing these wrong data entry, in the FM...as also i give info message for this in spool.
So can anybody tel me How can I detect or know this fields zdm_vld_to_dat conatins wrong date other than YYYYMMDD...e.g.
ct/-0/29-o   means any charecter or hyphen
Thank you.

Hi Nilesh Hiwale,
1. First thing is there is no need for any function module for difference between two dates
    See this.
Data:
days type i
date1 type wa_draw-zdm_vld_to_dat
date2 type sy-datum.
days = date2 - date1.
Write / days.
                      > (OR)
2. write this condition in PAI module of your screen.
At selection-screen.
if date1 cn '1234567890'. or date2 cn '123456789'.
write e000(Sabapdocu) with 'Enter YYYYMMDD Formate'.
endif.
Reward if it is useful,
Mahi.

How to validate for 2 decimal places

How can I put a check while inserting into a number(5,2) field that user has entered only 2 decimal places. Right now if the user inserts records like 23.5456 it gets inserted as 23.56 . I want these type of records to error out. Is there an easy way to do this kind of a validation while inserting.?
Thank You,
SK

Sorry, I don't see how you're going to accomplish this. The value has already been implicitly rounded before check constraints or triggers fire. I guess if they were inserting true literals you could check the SQL statement itself and it's possible to get at bind variable values but that's going to be a real nightmare to implement properly. I think you're going to have to have the column as a number with no scale and check constrain it if this is really required. You could probably do this with a view and instead of triggers but that's going to be ugly.

How to validate for a table name and field name parameters ?

Dear techies,
Kindly help me in validating two parameters.
1) table name (Date element = CDTABNAME ).
2) field name (Data Element = FIELDNAME ).
I need to know the master table which can be used to validate both the fields..........

You can validate it from table DD03L.

How to validate for-each path

I have following for-each path:
<?for-each:G_ACCT/LIST_G_INVOICENUM/G_INVOICENUM?>
However, sometimes there is no data for child group LIST_G_INVOICENUM. I want to check if no child group, then change the path to
<?for-each:G_ACCT?>
Is there a way to check the path exist or not?
Thanks.

It is like one parent have lot of kids. Now they want to show parent name for each kid.
<?for-each:G_ACCT?>
 display acct related infor here
 <?for-each:./LIST_G_INVOICENUM/G_INVOICENUM?>
 display invoice related info here
You can display all parent and grand parents here
 <?end for-each?>
<?end for-each?>
End user wants the parent elements being repeated. If I do the second for-each inside the first for-each, parent element will not be repeated.
will be repeated if you include the element with correct path
+<?for-each:G_ACCT/LIST_G_INVOICENUM/G_INVOICENUM?>+
However, sometimes there is no data for child group LIST_G_INVOICENUM. I want to check if no child group, then change the path to
+<?for-each:G_ACCT?>+
Is there a way to check the path exist or not?
<?if:/G_ACCT/LIST_G_INVOICENUM/G_INVOICENUM?> -- will return true if the element exists else falsewhy do you want to change the path ? i guess to display at least parent info

Unique Constraint

Hello,
OWM_VERSION: 11.1.0.7.0
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
I have a situation where somewhere along the line the primary key for a few records were thrown off. This is causing workspace manager to try and insert the T-520575 workspace records into LIVE when they are merged back together however this causes a unique constraint violation. Here is what the data looks like:
PK       UNQ1    UNQ2    WORKSPACE
2095989 495685 152568 T-520575
491685 495685 152568 LIVE
2095990 495687 152569 T-520575
491687 495687 152569 LIVE
2096052 495689 152570 T-520575
491689 495689 152570 LIVEI tried deleting the records out of the T-520575 workspace and refreshing the table using the following, but it still raises the unique constraint.
   delete from table
    where PK in( 2095989, 2095990, 2096052);
   dbms_wm.refreshtable(
      workspace    => 'T-520575',
      table_id     => 'TABLE',
      where_clause => 'PK in ( 491685, 491687, 491689)',
      auto_commit => FALSE
   );   I can see that the records I deleted have a WM_OPTYPE of 'D' but do not have a retiretime. How do I retire these records so that I can refresh them from LIVE? or is there a better solution to correct this issue?
Edit
I should also add that LIVE is the parent of this workspace T-520575
Thanks,
Tyson
Edited by: Tyson Jouglet on Apr 27, 2012 8:34 AM

Hi Tyson,
Are you sure there are no other rows that have a conflicting value for the unique constraint? What you have described should work. Since the rows have been deleted, they are no longer considered when evaluating the constraints when executing RefreshTable. You should be able to both merge and refresh the workspace after deleting the rows. Also, the row(s) with the 'D' wm_optype would not have a retiretime value, unless the row was reinserted. Only the 'I' or 'U' row(s) would have a retiretime value in this case.
If there are not any other rows, then I would need a more complete description. Are there any continuously refreshed workspaces that have T-520575 as a parent workspace? Those workspaces would also have to be checked.
Regards,
Ben

Cannot recreate unique constraint in 11gR2

In 10.1.0.2, I was able to first drop a unique constraint then recreate it as follows:
alter table OTPC_BLD_CHANGESET drop constraint UNQ_OTPC_BLD_CHANGESET_0;
ALTER TABLE OTPC_BLD_CHANGESET ADD CONSTRAINT UNQ_OTPC_BLD_CHANGESET_0 UNIQUE (NAME, OWNER, COMMIT_DATE);
However, when I tried to the same thing in 11.2.0.1, it complained:
ERROR at line 1:
ORA-00955: name is already used by an existing object
Could anyone tell me how I can recreate a unique constraint by dropping it and creating it? Thanks.

The problem is that YOU insist on using an object name that already exists.Not exactly. If you look at original post it says:

You can't get ORA-00955 while adding a constraint since it is not an object (table is while constraint isn't). If, for some reason, drop constraint failed then add constraint would result in:

Unique Constraint causes AppSetRollbackOnlyException

I have declared a unique constraint using the following annotation.
@Column(name="classname",columnDefinition="varchar(1024)",nullable=false,unique=true)
When trying to insert duplicate entities with the same name, essentially violating the constrain the following exception appears. It is not directly obvious what is causing this exception and it only is thrown during the commiting of the transaction, rather during the persist() which makes it difficult to intercept and handle.

Hi Tyson,
Are you sure there are no other rows that have a conflicting value for the unique constraint? What you have described should work. Since the rows have been deleted, they are no longer considered when evaluating the constraints when executing RefreshTable. You should be able to both merge and refresh the workspace after deleting the rows. Also, the row(s) with the 'D' wm_optype would not have a retiretime value, unless the row was reinserted. Only the 'I' or 'U' row(s) would have a retiretime value in this case.
If there are not any other rows, then I would need a more complete description. Are there any continuously refreshed workspaces that have T-520575 as a parent workspace? Those workspaces would also have to be checked.
Regards,
Ben

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:

>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?

MERGE statement; Google it. And do not use temp tables.
