Still learning the oracle, today we got one instance that, one of the trigger was compiled with dirty code, so at run time it threw an exception.(on Production Server)
so I just want to know that Is there any way to know that constraints as well as trigger are properly compiled?, just to avoid more instances like this.
Thanks
you mean by dirty code as errors right ? To know trigger or procedures which they are compiled with warning, check user_errors table:
select * from user_errors where name= '<procedure or trigger name>'
as for constraints (Primary key , foreign key , default values) they dont get created if they contains error.

I am using sequences to create IDs, so while executing insert stored procedure it will create unique value for ID. But after some time it is losing the definition for the sequence.
Not sure why this is happening again and again and how to solve the problem?
I am using Oracle SQL Developer and in the edit table property there is 'Identity Column' setting. See below:
Next step is setting up trigger and sequence:
It was working fine for some time until this property defaulted. Now it is not there anymore:
Still have this trigger and sequence object in the schema and able to setup again but it will break later.
How to avoid this problem in future?
I think it is just a bug/limitation in your client software, Oracle SQL Developer. The "Identity Column" tab is a handy way to create the corresponding sequence and trigger but it doesn't seem to recognise existing elements. I've just verified my own system and that's exactly what happens.
It makes sense, because adding a new sequence and trigger is a pretty straightforward task (all you need is a template) but displaying current sequence is hard given that a trigger can implement any conceivable logic. Surely it could be done but the cost-benefit ratio probably left things this way.
In short, your app is not broken so nothing needs to be fixed on your side.
This is what I received from IT support regarding the issue:
A few possibilities that might cause this:
1 - Another user with limited privileges might be editing the table using SQL Developer. In this case, if this user's privilege is not enough to obtain the sequence and/or trigger information from the database, the tool might leave the fields blank and disable it when table changes are saved.
2 - The objects are being changed or removed outside of SQL Developer, causing it to lose the information. In my tests I noticed that dropping the trigger and recreating it with the same name caused the identity property information to be lost on SQL Developer.
Even being the trigger enabled, and working for inserts it could not retrieve the information.
Then, if I run an alter trigger to enable it (even tough dba_trigger is reporting it as already enabled), SQL Developer will list the information again:
ALTER TRIGGER "AWS"."TABLE1_TRG" ENABLE;
So it looks like there are some issues with the SQL Developer, that is causing this behavior.
Next time it happen, please check if the trigger still exist on the database and is enabled with the query below:
select owner, trigger_name, TRIGGER_TYPE, TRIGGERING_EVENT, TABLE_OWNER, TABLE_NAME, STATUS
from dba_triggers
where trigger_name = 'ENTER_YOUR_TRG_NAME'; --Just change the trigger name in WHERE
I'm using a Win XP box with BDE Administrator and Access 2007 installed. I'm able to open and perform select queries on existing Paradox tables without problem but have some very strange behavior when attempting INSERT/UPDATE. I can even create a new Paradox table and it has the same behavior. Here is sample code:
' create new table
conObj.Execute "CREATE TABLE test (id INT, comment VARCHAR(30))"
' first insert works fine
conObj.Execute "INSERT INTO test VALUES (1, 'something')"
' second insert fails for unknown reason
conObj.Execute "INSERT INTO test VALUES (2, 'something else')"
I've tried using Jet 4.0, MS Access Paradox driver, and native Paradox driver connection strings but all yield the same result. On the second insert statement it throws an error:
Operation must be an updateable query
I've read numerous posts in forums and pages on help sites that tell me this error is caused by a file permissions issue. The account running this script is part of the Administrator group and I've changed file permissions to allow the Everyone group Full Control of the db file but this changes nothing.
This page put out by Micrsoft Support did not fix the problem: http://support.microsoft.com/kb/175168
Additionally, I can create a new table but any time I try to create a PRIMARY KEY or UNIQUE field I get an error message that says:
"Index_[random characters] is not a valid name."
try
"CREATE TABLE test (id INT, comment VARCHAR(30), primary key(id))"
I don't know much about Paradox databases but this has indeed been a learning experience. Even though I have a table file called table.db that's not enough to store more than a single row of data. I also need several other files to insert or update a paradox database:
table.DB
table.PX
table.VAL
table.XG0
table.XG1
table.YG0
table.YG1
I was nosing around in another program that generates paradox databases and found when I copied a blank database from it along with these other files it generated I was able to insert and update without problems. I have no idea what these files are for or why they need to be present to insert or update but having them present fixed my issue.
I have a - for me unknown - issue and I don't know what's the logic/cause behind it. When I try to insert a record in a table I get a DB2 error saying:
[SQL0803] Duplicate key value specified: A unique index or unique constraint *N in *N
exists over one or more columns of table TABLEXXX in SCHEMAYYY. The operation cannot
be performed because one or more values would have produced a duplicate key in
the unique index or constraint.
Which is a quite clear message to me. But actually there would be no duplicate key if I inserted my new record seeing what records are already in there. When I do a SELECT COUNT(*) from SCHEMAYYY.TABLEXXX and then try to insert the record it works flawlessly.
How can it be that when performing the SELECT COUNT(*) I can suddenly insert the records? Is there some sort of index associated with it which might give issues because it is out of sync? I didn't design the data model, so I don't have deep knowledge of the system yet.
The original DB2 SQL is:

I'd like to see the statements...but since this question is a year old...I won't old my breath.
I'm thinking the problem may be the
GENERATED BY DEFAULT
And instead of passing NULL for the identity column, you're accidentally passing zero or some other duplicate value the first time around.
Either always pass NULL, pass a non-duplicate value or switch to GENERATED ALWAYS
Look at preceding messages in the joblog for specifics as to what caused this. I don't understand how the INSERT can suddenly work after the COUNT(*). Please let us know what you find.
Since it shows *N (ie n/a) as the name of the index or constraing, this suggests to me that is is not a standard DB2 object, and therefore may be a "logical file" [LF] defined with DDS rather than SQL, with a key structure different than what you were doing your COUNT(*) on.
Your shop may have better tools do view keys on dependent files, but the method below will work anywhere.
If your table might not be the actual "physical file", check this using Display File Description, DSPFD TZVDB.PRODUCTCOSTS, in a 5250 ("green screen") session.
Use the Display Database Relations command, DSPDBR TZVDB.PRODUCTCOSTS, to find what files are defined over your table. You can then DSPFD on each of these files to see the definition of the index key. Also check there that each of these indexes is maintained *IMMED, rather than *REBUILD or *DELAY. (A wild longshot guess as to a remotely possible cause of your strange anomaly.)
You will find the DB2 for i message finder here in the IBM i 7.1 Information Center or other releases
Is it a paging issue? we seem to get -0803 on inserts occasionally when a row is being held for update and it locks a page that probably contains the index that is needed for the insert? This is only a guess but it appears to me that is what is happening.
I know it is an old topic, but this is what Google shown me on the first place.
I had the same issue yesterday, causing me a lot of headache. I did the same as above, checked the table definitions, keys, existing items...
Then I found out the problem was with my INSERT statement. It was trying to insert to identical records at once, but as the constraint prevented the commit, I could not find anything in the database.
Advice: review your INSERT statement carefully! :)
I apologize for posting a question that seems to have been asked numerous times on the internet, but I can't quite fix it for some reason.
I was trying to populate some tables using Oracle's magical sqldr utility, but it throws an ORA-01775 error for some reason.
Everywhere I go on Google, people say something along the lines of: "Amateur, get your synonyms sorted out" (that was paraphrased) and that's nice and all, but I did not make any synonyms.
Here, the following does not work on my system:
SQLPLUS user/password
SQL>CREATE TABLE test (name varchar(10), id number);
SQL>exit
Then, I have a .ctl file with the following contents:
load data
characterset utf16
infile *
append
into table test
(name,
id
)
begindata
"GURRR" 4567
Then I run this command:
sqlldr user#localhost/password control=/tmp/controlfiles/test.ctl
The result:
SQL*Loader-702: Internal error - ulndotvcol: OCIStmtExecute()
ORA-01775: looping chain of synonyms
Part of test.log:
Table TEST, loaded from every logical record.
Insert option in effect for this table: APPEND
Column Name Position Len Term Encl Datatype
------------------------------ ---------- ----- ---- ---- ---------------------
NAME FIRST 2 CHARACTER
ID NEXT 2 CHARACTER
SQL*Loader-702: Internal error - ulndotvcol: OCIStmtExecute()
ORA-01775: looping chain of synonyms
And, if I try to do a manual insert:
SQL> insert into test values ('aa', 56);
1 row created.
There is no problem.
So, yeah, I am stuck!
If it helps, I am using Oracle 11g XE on CentOS.
Thanks for the help guys, I appreciate it.
EDIT:
I kind of, sort of figured out part of the problem. The problem was that somewhere along the line, maybe during a failed load or something, Oracle had given itself corrupt views and synonyms.
The affected views were: GV_$LOADISTAT, GV_$LOADPSTAT, V_$LOADISTAT and V_$LOADPSTAT. I am not quite sure why the views got corrupt, but recompiling them resulted in compiled with errorserrors. The synonyms used in the queries themselves were corrupt, namely the gv$loadistat, gv$loadpstat, v$loadistat and v$loadpstat synonyms.
I wasn't sure about why this was happening and I didn't quite understand anything. So, I decided to drop the synonyms and recreate them. Unfortunately, I couldn't recreate them, as the view they pointed to (there is a bit of weird recursion going on here...) was corrupt. These views were the aforementioned GV_$LOADISTAT and other views. In other words, the synonyms pointed to the views that used those synonyms. Talk about a looping chain.
So...I recreated the public synonyms but instead of specifying the view as GV_$LOADISTAT, I specified them as sys.GV_$LOADISTAT. e.g.
DROP PUBLIC synonym GV$LOADISTAT;
CREATE PUBLIC synonym GV$LOADISTAT for sys.GV_$LOADISTAT;
Then, I recreated the user views to point to those public synonyms.
CREATE OR REPLACE FORCE VIEW "USER"."GV_$LOADISTAT" ("INST_ID", "OWNER", "TABNAME", "INDEXNAME", "SUBNAME", "MESSAGE_NUM", "MESSAGE")
AS
SELECT "INST_ID",
"OWNER",
"TABNAME",
"INDEXNAME",
"SUBNAME",
"MESSAGE_NUM",
"MESSAGE"
FROM gv$loadistat;
That seemed to fix the views/synonyms. Yeah, it is a bit of a hack, but it somehow worked. Unfortunately, this was not enough to run SQL Loader. I got a table or view does not exist error.
I tried granting more permissions to my regular user, but it didn't work. So, I gave up and ran SQL Loader as sysdba. It worked! It is not a good thing to do, but it is a development only system made for testing purposes, so, I didn't care.
I could not repeat your looping synonym chain error, but it appears the control file needed a bit of work, at least for my environment.
I was able to get your example to work by modifying it thusly:
load data
infile *
append
into table test
fields terminated by "," optionally enclosed by '"'
(name,
id
)
begindata
"GURRR",4567
I'm trying to add an attribute to an already existing Object Type in an Oracle 10.2.0.4 DB.
The schema is valid, and everything is working before running the following statement:
ALTER TYPE sometype ADD ATTRIBUTE (somefield varchar(14))
CASCADE INCLUDING TABLE DATA
/
SHOW ERRORS
The alter fails with an ORA-22324 and an ORA-21700.
Afterwards most of the schema objects which depend on sometype are invalid.
Compiling them all, restores the schema to a working state.
Anyone seen that kind of error?
ORA-22324 is "Altered type has compilation errors", and ORA-21700 is "Object does not exist or is marked for delete". Sounds like the body of your type may be referencing something which has been deleted.
I hope this helps.
I know this is old, but my answer may help people who find this later.
Make sure to disconnect and reconnect if your getting this, Its possible that will solve your issue.
However, Understanding the oracle Dev guide before altering types is important(especially when you have tables using the type):
Here is the object dev guide for oracle 9i:
http://docs.oracle.com/cd/B10501_01/appdev.920/a96594.pdf
Also points to recompiling the body
http://database-geek.com/2005/05/26/oracle-objects-types-and-collections-part-3/
EXEC DBMS_UTILITY.compile_schema(schema => 'SOME_SCHEMA'); --may also provide a useful results for you if you have alot of stuff that became invalid with your change.
