In this case your statement will use null for all DISTINCTTRIM (CM_CUST_NAME) And if you have more then one you would have a duplicate PK... So you would need to give the PK a unique not null value. 0 Kudos Reply donal28 Enthusiast Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Get Direct Link Print Email to
SQL JOINS , we sometime may face DUPLICATE PRIMARY KEY ERROR. This error may especially come while tables containing history are included in JOIN conditions. So while using SQL Joins, we must take care
Duplicate Unique Prime Key Error Informatica
of this problem. Let us look into this problem in more detail: Duplicate Unique duplicate unique prime key error world of warcraft Primary Key Error in Teradata Suppose we have a table which is maintaining history of all the CUSTOMERS. And we do a unique primary index in teradata join with this table with some other table on the basis of CUST_ID (key column in this case) . Since the table is maintaining history of CUSTOMERS, so it will be having multiple entries for http://community.teradata.com/t5/Database/Error-from-Insert-Select-statement/td-p/57936 same CUST_ID. So if the join condition is on CUST_ID, it will result in one to many mapping and the result set will also have multiple entries for same CUST_ID. Now if the target is having CUST_ID as primary key, it will throw UNIQUE PRIMARY KEY violation error. So how to avoid such situation ? The easiest way of overcoming this issue is to fetch the latest entry of CUST_ID http://usefulfreetips.com/Teradata-SQL-Tutorial/remove-duplicate-unique-primary-key-error/ from the history table. So in that case, it will be fetching only one instance of each CUST_ID even if multiple entries exists. Now we will see how we can implement this using the SQL in Teradata. If the table is maintaining history in the table then it must be having a date column which will be useful in maintaining history. So you can put a condition on the date column to fetch only the latest row when multiple exists for same key. Let us see how you can implement this check in Teradata: SELECT CUST_ID , CUST_NAME,CUST_CITY FROM CUSTOMERS QUALIFY ROW_NUMBER() OVER (PARTITION BY CUST_ID ORDER BY DAT_UPD DESC)=1; This query will fetch only one instance of each row. So you can add this clause at the end of any SQL query involving tables with multiple entries for same key. This way you can avoid UNIQUE PRIMARY KEY violation error.

Over the past month, however, ELMAH has been intermittently key error in reporting the following exception from our .NET 4.0 ASP.NET app: Teradata.Client.Provider.TdException: [Teradata Database] [2801] Duplicate unique prime key error in DATABASENAME.TABLENAME. I was able to replicate it by opening SQL Assistant and inserting a bunch of records into the table with raw SQL. As expected, most of the time it would insert successfully, but other times it would throw the above exception. It appears that this error is occuring because Teradata is trying to generate a value for this column that it has previously generated. Does anyone have any idea how to get to the bottom of what's happening? At the very least, I'd like some way to debug the issue a bit deeper. unique identity teradata share|improve this question asked Jul 30 '12 at 19:06 oscilatingcretin 2,8261468131 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote I would suggest changing the definition of your identity column to GENERATED ALWAYS to prevent the application or ETL process from supplying a value that could have been used. In fact, it is recommended by Teradata that if you are using your IDENTITY column as part of a UPI that it should be defined as GENERATED ALWAYS ... NO CYCLE EDIT: If your business

Windows Errors
A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
Blue Screen of Death
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
Damaged DLLs
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Freezing Computer
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Virus Damage
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
