Yes, for MS SQL7 modify the EasySQL vi to execute the SQL command 'SELECT
@@IDENTITY' the query results will contain the identity of the inserted row.

Checking for duplicate primary keys on row inserts

Checking for duplicate primary keys on row inserts
I have a situation where I will be making bulk table inserts knowing that the primary key value will in some cases already exist. In this is the case I simply want to ignore the duplicate inserts.
Should I be performing a sub-query on the table and using a statement like:
where not exist in
Or is there a cleaner way of discarding or checking for duplicates on insert.
My concerns were mainly one of performance, as my routine will be inserting a few thousand rows in its operation.

The MERGE commnad is a good option when a large percentage of the data will exist in the target because it is much more efficient to attempt to update then insert when the update affects zero rows than capture an error and convert it to an update.
However, since in this case it would appear that only a few rows will alreadys exist and we want to ignore the duplicates when they exist then
begin
insert
exception
when dup_value_in_index then null;
end
would be the way to code this one. The bulk insert version has in 9.2 the ability to store the errors so that they can all be handled at once which means the rest of the array insert can work.

Primary key violation when inserting records with insert_identity and ident_current+x

My problem is this: I have data in a couple of temporary tables including
relations (one table referencing records from another table by using
temporary keys).
Next, I would like to insert the data from the temp tables to my productive tables which have the same structure but their own identity keys. Hence, I need to translate the 'temporary' keys to regular identity keys in my productive tables.
This is even more difficult because the system is highly concurrent, i.e. multiple sessions may try to insert
data that way simultaneously.
So far we were running the following solution, using a combination of
identity_insert and ident_current:
create table doc(id int identity primary key, number varchar(100))
create table pos (id int identity primary key, docid int references doc(id), qty int)
create table #doc(idx int, number varchar(100))
create table #pos (docidx int, qty int)
insert #doc select 1, 'D1'
insert #doc select 2, 'D2'
insert #pos select 1, 10
insert #pos select 1, 12
insert #pos select 2, 32
insert #pos select 2, 9
declare @docids table(ID int)
set identity_insert doc on
insert doc (id,number)
output inserted.ID into @docids
select ident_current('doc')+idx,number from #doc
set identity_insert doc off
-- Since scope_identity() is not reliable, we get the inserted identity values this way:
declare @docID int = (select min(ID) from @docids)
insert pos (docid,qty) select @docID+docidx-1, qty from #pos
Since the request to ident_current() is located directly in the insert statement, we always have an implicit transaction which should be thread safe to a certain extend.
We never had a problem with this solution for years until recently when we were running in occasional primary key violations. After some reasearch it turned out, that there were concurrent sessions trying to insert records in this way.
Does anybody have an explanation for the primary key violations or an alternative solution for the problem?
Thank you
David

>> My problem is this: I have data in a couple of temporary tables including relations (one table referencing records [sic] from another table by using temporary keys [sic]). <<
NO, your problem is that you have no idea how RDBMS and SQL work.
1. Rows are not anything like records; this is a basic concept.
2. Temp tables are how old magnetic tape file mimic scratch tapes. SQL programmers use CTEs, views, derived tables, etc.
3. Keys are a subset of attributes of an entity, fundamental characteristics of them! A key cannot be temporary by definition.
>> Next, I would like to insert the data from the temp tables to my production tables which have the same structure but their own IDENTITY keys. Hence, I need to translate the 'temporary' keys to regular IDENTITY keys in my productive tables. <<
NO, you just get worse. IDENTITY is a 1970's Sybase/UNIX dialect, based on the sequential file structure used on 16-bit mini computers back then. It counts the physical insertion attempts (not even successes!) and has nothing to with a logical data model. This
is a mag tape drive model of 1960's EDP, and not RDBMS.
>> This is even more difficult because the system is highly concurrent, i.e. multiple sessions may try to insert data that way simultaneously. <<
Gee, that is how magnetic tapes work, with queues. This is one of many reasons competent SQL programers do not use IDENTITY.
>> So far we were running the following solution, using a combination of IDENTITY_INSERT and IDENT_CURRENT: <<
This is a kludge, not a solution.
There is no such thing as a generic “id” in RDBMS; it has to be “<something in particular>_id” to be valid. You have no idea what the ISO-11179 rules are. Even worse, your generic “id” changes names from table to table! By magic, it starts as a “Doc”,
then becomes a “Pos” in the next table! Does it wind up as a “doc-id”? Can it become a automobile? A squid? Lady Gaga?
This is the first principle of any data model; it is based on the Law of Identity; remember that from Freshman Logic 101? A data element has one and only one name in a model.
And finally, you do not know the correct syntax for INSERT INTO, so you use the 1970's Sybase/UNIX dialect! The ANSI/ISO Standard uses a table consrtuctor:
INSERT INTO Doc VALUES (1, 'D1'), (2, 'D2');

You have been mimicking a mag tape file system and have not written correct SQL. It has caught up with you in a way you can see. Throw out this garbage and do it right.

Primary Key Conflicts While Inserting Rows

Hi,
I am inserting some rows into a table which has primary key constraints on columns 1,2,3. I have set the key columns in my program to 1,2,3. When I try to insert a row it throws a syncresolver exception stating that there is a key conflict. But i don't understand why it is doing this because there is no conflict. I can remove the primary key constraints off the sql table (but still leave them on in the program) and it will insert everything correctly.
Any ideas?
Thanks

I inserted the exact same data manually into the DB and it works fine.
By the way, the program inserts the first row, but not the second. Based on my trials with the original program I am working on the syncproviderexception handler seems to have a conflict on insert row on Switch column. This is why I believe java is not interpreting the PKs as a group but rather as individually.

Urgent - ESB: DB Adapter with composite primary keys no returning any data

I have a DB Adapter in the ESB that inserts/updates/selects data to/from a table with 2 columns as primary keys, but table has several columns.
1. Initially, the db table had constraints for the composite primary key, The DB adapter had valid data coming in, but no result data.
2. Then I removed the db constraints on the composite primary key, and selected the 2 columns in the DB adapter wizard. Still, valid data is going in, since I am outputing to a file prior to call this node, but no result data is appearing. The result XML is empty.
Do I need to do something in Toplink for this?
The table spec is below. the ACCT_FIELD and ACCT_CODE columns make up the composite primary key.
CREATE TABLE AFF_DATA_SYNC

ACCT_CODE VARCHAR2(16) NOT NULL,

Primary key generation by insert trigger.

I have a table and wish to automatically create a unique sequence number for use as the primary key.
In PL/SQL I do something like this:
create sequence personnel_seq;
create or replace trigger personnel_insert
before insert on personnel
for each row
declare seqNo NUMBER;
begin
select personnel_seq.NextVal into seqNo from dual;
:new.vc_personnel_reference := seqNo;
end personnel_insert;
column personnel.vc_personnel_reference is the primary key of table personnel, and not null.
What's the recommended way to do something similar in BC4J?
At present I'm using the trigger but BC4J doesn't know it exists, and insists on a value for vc_personnel_reference being provided. It also insists on adding the primary key to the ViewObject's attributes.
I can provide a dummy value in ViewObjectRowImpl.insertRow() but this seems cumbersome.
Is there a better way?
In fact can I do this kind of thing entirely in BC4J without the trigger?
Tony.

But be carefull with DBSequences.
There's a "problem" because the DBSequencs is a Domain and a "domained" field is not equal to any other field.
In that case if have an Entity with Id = 1 (where d comes out from a DbSequence) and You look for Id = n where n is a Number containing 1, You will not find Your record !!!
As 9.0.2.; I don't know in 9.0.3.

SQL Server - primary key constraint modify

Hi,
I have a table with many records. I wanted to modify the primary key constraint. The only way to alter the primary key constraint is to drop and create again. Please let me if it is right.
Can we create primary key constraint with NoCheck. Since we have lots of records in our table, creating primary key constraint takes more time because it is checking the existing data. Please provide your comments.
Thanks.

http://technet.microsoft.com/en-us/library/ms181043(v=sql.105).aspx
Note
To modify a PRIMARY KEY constraint, you must first delete the existing PRIMARY KEY constraint and then re-create it with the new definition.

http://msdn.microsoft.com/en-IN/library/ms188066.aspx
When FOREIGN KEY or CHECK constraints are added, all existing data is verified for constraint violations unless the WITH
NOCHECK option is specified. If any violations occur, ALTER TABLE fails and an error is returned. When a new PRIMARY KEY or UNIQUE constraint is added to an existing column, the data in the column or columns must be unique. If duplicate values are found, ALTER
TABLE fails. The WITH NOCHECK option has no effect when PRIMARY KEY or UNIQUE constraints are added.

?Trigger to return primary key value after insert"

Ok, so I'm a newbie to oracle. I was hoping someone could tell
me how I can get the value of a field after insertion. I
created a sequence and a trigger to autoincrement the primary
key. I figured out that select @@Identity does not work. So
I'm trying to figure out how to return the primary key value of
just inserted record.
Any help or suggestions would be really appreciated.
thanks matt

when a record is inserted into the collector table - I want to fire a trigger and insert the value of "collector.a_test", "collector.b_test" into "master.test" and "detail.test" respectively.
I want to create an after/insert trigger on the collector table to accomplish this. I tried to implement the example listed in previous message (see below) *** BUT **** I get a PLS-00103 error - "Encountered the symbol "A_ID" when expecting one of the following: :=. ( @ %;

Primary Key Multiple Column with Date - parameter issue

All,
I am having an issue that I cannot find the answer to. I have looked high and low to no avail. Please help.
The issue at hand is that I have a table that has a multiple column primary key and one of the columns happens to be a date and the other is a string. I have a basic search and I want an update picture in the results table that the users can click on and go to a different page to update that record. The issue is when I fire an action based on the update picture I also want to set parameters based on the record that I selected. So I set the string parameter and that works fine. The issue is with the date. When i set the date parameter it works but it chops off the timestamp. Later when I try to get this parameter 'pageContext.getParameter("dateParameter");' it will bring in a date like 15-Dec-2008 but I need the entire date and timestamp (i.e. 15-Dec-2008 10:20:33) to correctly identify the record.
Please help!
Thanks,
Colby J

Hi
since every parameter go in url as a string format so u will never get the date parameter with complete timestamp,the solution would de
1.) Set a fire action on update picture,give its event name as "update",
2.) clicking on update picture will fire this event .
3.) in processFormrequest method of controller
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if ("update".equals(pageContext.getParameter("event")))
// this will give the select row where update is clicked
String rowReference = pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
VORowImpl row = (EmployeeSummaryVORowImpl)am.findRowByRef(rowReference);
Timestamp sdateVal=(String)row.getAttribute("Date value");
// this will transfer the values to next page
pageContext.putTransactionTransientValue("transferdvalue",sdateVal);
// and in the next page u can get the value like this
timestamp getDateVal=pageContext.getTransactionTransientValue("transferdvalue"l);
hope this will resolve your issue,Please let me know if u face any issue
thanx

SQL API. Database corrupted when inserting data?

Hi, I have a working sqlite application I was going to migrate to BerkeleyDB to try and solve some locking issues. However I am having some trouble creating the database.
I downloaded the windows pre-built binaries and created my schema with dbsql.exe. The DDL worked fine and running db_verify reported no errors. However after I inserted about twenty rows of data using a SQL script of INSERT commands db_verify reported about ten "out-of-order key" messages. There are no INSERT triggers in the DDL. I tried running the INSERTs as single commands, and the out-of-order key messages appeared after about ten rows of data. A bit of googling only revealed that these errors often occur when using tools linked to different BerkelyDB versions. I have never had any version of BerkeleyDB installed before.
I then downloaded the BerkeleyDB source and built the binaries myself. I again created the schema - no problems, inserted about twenty rows - errors the same as before. When running db_recover the error messages are as below:
C:\Program Files (x86)\Oracle\Berkeley DB 11gR2 5.1.25\bin\SFTPVT.BDB-journal>..\db_recover.exe
db_recover.exe: Ignoring log file: log.0000000001: magic number 1563f1a3, not 40988
db_recover.exe: Invalid log file: log.0000000001: Invalid argument
db_recover.exe: PANIC: Invalid argument
db_recover.exe: process-private: unable to find environment
db_recover.exe: DB_ENV->open: DB_RUNRECOVERY: Fatal error, run database recovery
I thought the issues might be because I use encrypted database but the same things happen whether I use PRAGMA key="****************" in my scripts or not. I haven't played with DB_CONFIG - should I be creating a DB_CONFIG yet?
I'm using Win 7 pro (x64), i5 processor with 8GB RAM, disks are a RAID10 array formatted as NTFS. Same errors occur if I try to create the database on a FAT32 USB key so it's probably not a filesystem problem. I used Visual Studio 10 and MSVCRT version 10 when building binaries myself. I notice the downloaded binaries were built against MVCRT version 8, so the problem doesn't look tied to the version of the VC runtime as it occurs on multiple versions.
Can anybody help please? I would like to try BerkeleyDB but can't get past the first hurdle.

Hello,
If you can provide a small stand-alone program to reproduce the problem along with the steps to reproduce it, I will give it a try.

Primary key values

hi
i have created table like.
create table sample(sid varchar2(10) primary key, sno number);
inserted data like this
sid sno
AB10 10
BA11 11
AB12 11
now i want to insert values into sid at frontend side..
here my job here i want io insert values into sid(PK) from backend
suppose ifs sid is number type
i can insert values like select stmt..
like
select decode(max(sid), null,1,max(sid)+1) into variable from table_name;
but here sid is varchar2 type
so how to compare the value into database before value was inserted.???

Why you dont use a number as a data type of your PK

Populating primary key from My SQL

I have a table called MEMBERS in MY SQL with BEFORE INSERT trigger on it to create the primary key. Trigger works when I use the MYSQL prompt to insert. By Using BC in 10.1.3 , I want to populate the primary key (memberid) when insert any record in to this table. In the model, 'primary key','& TRansient' are the only properties selected for the entity.
When I insert using BC the record in not being created. How do I make it work.
Following is the trigger on the table.
CREATE OR REPLACE TRIGGER ASSIGN_MEM_ID
BEFORE INSERT ON MEMBERS FOR EACH ROW
BEGIN
IF :NEW.MEMBERID IS NULL OR :NEW.MEMBERID < 0 THEN
SELECT memid
INTO :NEW.MEMBERID
FROM MemberSequence;
UPDATE MemberSequence
SET memid= memid+1;
END IF;
END;
Any help is appreciated.
Thanks

Try using the DBSequence data type for the column.

Violation of PRIMARY KEY constraint 'PK_EMPLOYEE'. Cannot insert duplicate key in object 'EMPLOYEE'.
I didnt set identity for primary key. If i try to set identity to true then it is allowing data to submit only if i uncheck my primary key column in cached row set. And if i uncheck that primary key element then i can not retrieve the data by edit button. So how to solve this problem.
Please any help would be appreciated.
Thank You in Advance.

Hi,
I am providing support to one of our clients, where we have jobs scheduled to load the data from the tables in the source database to the destination database via SSIS packages. The first time load is a full load where we truncate all the tables in the destination
and load them from the source tables. But from the next day, we perform the incremental load from source to destination, i.e., only modified records fetched using changed tracking concept will be loaded to the destination. After full load, if we run the incremental
load, the job is failing with the error on one of the packages "Violation of PRIMARY KEY constraint. Cannot insert duplicate key in object '<tablename>'. The duplicate key value is <1234>, even though there are no duplicate records. When we
try debugging and running the failing package, it runs successfully. We are not able to figure out why the package fails and when we run the next day it runs successfully. Request you to help me in this regard.
Thank you,

I suspect you are trying to insert modified records instead of updating.

Using a custom PL/SQL to populate the primary key in a tabular form

I want to use a Custom PL/SQL Function to populate the primary key when I insert a new record into a tabular form. I want to get the value from a hidden page Item. The code I am using for the primary key source is:
BEGIN
INSERT INTO TEAM_MEMBERS(TEAM_ID)
VALUES(:P75_TEAM_ID);
END;
When I try to insert a new record I get the following error:
Error ERR-1904 Unable to compute item default: type = Function Body computation_type= BEGIN INSERT INTO TEAM_MEMBERS(TEAM_ID) VALUES(:P75_TEAM_ID); END; .
ORA-06550: line 5, column 2: PLS-00103: Encountered the symbol ";" when expecting one of the following: begin case declare end exception exit for goto if loop mod null pragma raise return select update while with << close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe The symbol "exit" was substit
Any ideas what I am doing wrong?
Thanks!

Brian - Sometimes whitespace at the end of the block causes this. Be sure to trim everything after the last semicolon including tabs and newlines.

Triggers to insert primary key

I have two tables in database namely CM_BOM and CM_BOM_ITEM. The table columns are as follows :
In CM_BOM table
CR_ID
CR_BOM_CODE
CR_BOM_NAME
CR_FG_CODE
CR_ID is primary key
Trigger to insert primary key data is as follows :
CREATE OR REPLACE TRIGGER COSTMAN."CM_BOM_T1"
BEFORE INSERT ON "CM_BOM"
FOR EACH ROW
DECLARE
L_ID NUMBER;
BEGIN
IF :NEW.CR_ID IS NULL THEN
:NEW.CR_ID := CM_RECIPE_SEQ.NEXTVAL; --L_ID;
END IF;
END;
In CM_BOM_ITEM table
CR_ID
CR_ITEM_ID
CR_FG_CODE
CR_RM_CODE
CR_RM_QTY
CM_ITEM_ID is primary key. Trigger to insert primary key data is as follows :
CREATE OR REPLACE TRIGGER COSTMAN."CM_BOM_ITEM_T1"
BEFORE INSERT ON "CM_BOM_ITEM"
FOR EACH ROW
DECLARE
L_ID NUMBER;
BEGIN
IF :NEW.CRI_ITEM_ID IS NULL THEN
:NEW.CRI_ITEM_ID := CM_RECIPE_SEQ.NEXTVAL;
END IF;
END;
Now, i want to the CR_ID in table CM_BOM_ITEM to get automatically inserted while adding any rows in the table.
How could i do this ? Please suggest ?

In your code where you perform the insert into the parent table, you can use the RETURNING clause to receive the primary key value that the trigger on the parent table has assigned to the parent-row that was just inserted.
insert into parent_table(....) values(....)
returning CR_ID into some_local_variable;Then use this value when you insert the foreign key row subsequently.
