IBM DB2 is a family of relational database server products developed by IBM that have been extended to support object-relational features and non-relational structures like JSON and XML. There are three main products in the DB2 family: DB2 for Linux, UNIX and Windows (informally known as DB2 LUW), DB2 for z/OS (mainframe), and DB2 for i (formerly OS/400), plus a version for IBM's Virtual Storage Extended (VSE) operating system.

SAP R3 BOM Explosion Query

I have the need to get a BOM with all components , currently using Tc. CK86 , but this doesn't give enough information, so I want to do this by SQL, I come from oracle background and dont know how could I get this done in DB2 R/3, I do not have access to query builder or quickview , but i do have read access via SQL, I'm currently trying to figure out a way of getting this info using tables :

MAST Material to BOM Link
STKO BOM Header
STPO BOM item

Does any of you have a solution for this?

In Oracle I did something like the following:

SELECT DISTINCT LEVEL
	,sys_connect_by_path(msil.segment1, ' @ ') AS "BOM TREE"
	,msi.segment1
	,lpad(' ', LEVEL, '') || msil.segment1 Cod_Component
	,msil.item_type
	,msil.description Desc_Component
	,BIC.component_quantity
	,msiL.primary_unit_of_measure
FROM mtl_system_items msi
	,bom_bill_of_materials bom
	,BOM_INVENTORY_COMPONENTS BIC
	,MTL_SYSTEM_ITEMS MSIL
WHERE msi.organization_id = 332
	AND BOM.ASSEMBLY_ITEM_ID = MSI.INVENTORY_ITEM_ID
	AND BOM.ORGANIZATION_ID = MSI.ORGANIZATION_id
	AND bom.bill_sequence_id = bic.bill_sequence_id
	AND nvl(bic.disable_date, sysdate) >= SYSDATE
	AND BIC.component_ITEM_ID = MSIL.INVENTORY_ITEM_ID
	AND Bom.ORGANIZATION_ID = MSIL.ORGANIZATION_ID
	AND msil.inventory_item_status_code = 'Active'
	AND msi.inventory_item_status_code = 'Active' connect BY prior bic.component_item_id = bom.assembly_item_id
	START
                  WITH msi.segment1 = trim(:parte)
        ORDER BY 2

Hi All,

I could be going about this completely wrong; however, I'm working with a field that is originally a number; however, I need to use the Like command in a where clause to isolate certain results. To further compound this, I need to use the left command to have the where clause only look at the first 5 characters.

Here is what I have so far:

CAST(MBRLOG.MLCHDT AS VARCHAR(7)) LIKE(LEFT(Date_Table.EligMstrConvert, 5))

I don't always use sql with db2 so I might be slightly off on my logic, but any help or suggestions here would be greatly appreciated.

I need to combine address fields(addr_1, addr_2, City, St_cd, zip) into new Mail_Address field where most of the time the addr_2 contains null using DB2

In sql server I can do
rtrim(ltrim(a.addr_1)) + ' ' + rtrim(ltrim(isnull(a.addr_2,''))) + ', ' + rtrim(ltrim(a.City)) + ', ' + rtrim(ltrim(a. St_cd)) + ', ' + rtrim(ltrim(a.zip))
but unable to use in DB2.

I've tried a.addr_1 || '' '' || a.addr_2 || '', '' || a.City || '', '' || a.St_cd || '', '' || a.zip which only return a value in the new field if all fields are not null

I've also tried
Coalesce(a.addr_1,'') || '' '' || Coalesce(a.addr_2,'') . This only returned what was in a.addr_1 even if a.addr_2 wasn't null and I couldn't add the city, st_cd or zip to the coalesce

I had this question after viewing Number of Weeks in a particular month.

This works great for Saturday but I my week starts on Monday (day 1). How do I change this so that I can pick a different day, example, Monday (first day) or Sunday (last day) of the week.
Thank you!

We have prod environment and development environment for DB2 .

1> we are thinking of proposing have a nick schema in dev pointing to prod .
in this case we will need to make sure only specific user id will have access to these nick schema .
is it possible to do that ?

2> if we fire select on nick schemas< with ur > ; Is it sure that we will not lock not lock the database tables .

3> Is there any way of controlling database load on the prod databases when queries are fired by nick schema ?

Greetings!

As I make my transition from working on "DB2 for I" to "DB2 for z/OS", I'm finding subtle differences that are tripping me up.

For example, I copied the following simple stored procedure from a website:

CREATE PROCEDURE MYSCHEMA.UPDATE_SALARY_1 (
  IN EMPLOYEE_NUMBER CHAR(10),
  IN RATE NUMERIC(6,2))
LANGUAGE SQL
MODIFIES SQL DATA
  UPDATE MYSCHEMA.EMP
     SET SALARY = SALARY * RATE
   WHERE EMPNO = EMPLOYEE_NUMBER

Open in new window

But, when creating the procedure, it throws the following error:

WLM ENVIRONMENT NAME MUST BE SPECIFIED

I googled that error, and it was recommended that I add "DISABLE DEBUG MODE":

CREATE PROCEDURE MYSCHEMA.UPDATE_SALARY_1 (
  IN EMPLOYEE_NUMBER CHAR(10),
  IN RATE NUMERIC(6,2))
LANGUAGE SQL
MODIFIES SQL DATA
DISABLE DEBUG MODE
  UPDATE MYSCHEMA.EMP
     SET SALARY = SALARY * RATE
   WHERE EMPNO = EMPLOYEE_NUMBER

Open in new window

But, it now throws these errors:

REBIND AUTHORIZATION ERROR USING MYSCHEMA AUTHORITY PACKAGE =
LOCDBT1.MYSCHEMA.UPDATE_SALARY_1.(V1) PRIVILEGE = BIND.

What am I doing wrong?

Thanks for your help!

I had this question after viewing iSeries DB2 SQL - Request user input.

I also have similar requirement and code also follows:-

Sub ChangeQueryVariables()
DIM ssql AS String, NUM AS Interger
Dim qd as dao.QueryDef,db as dao.Database

Set db=CurrentDb()
Set qd=db.QuerDefs("BM")

ssql=select ABAN8,ABALPH from ascrpdta.F0101 where ABAN8=&NUM"
qd.SQL=ssql
Do cmd.OpenQuery "BM"x
End sub

And error is

Hi,

Can we have CDC data mirroring between 2 different version servers.
Example a table is in V5R3 and we create the same table in V7R2 and we would like to have the data replicated from V5R3 to V7R2.

Is this possible. Do you see any issues.

Thanks
Chaitu

newbie on DB2 for z/OS

Greetings, experts!

After almost 25 years of working primarily on DB2 for the midrange (AS/400, IBM i), I now have a new job where I need to quickly come up to speed on DB2 for the mainframe (z/OS). Fortunately, the system catalogs in the SYSIBM schema look to be almost the same, so I’ve been able to glean some information about the database-layout from there. But, I keep thinking, “There HAS TO be a better way!”

For example, on DB2 for i, there’s a fat-client GUI application (called “System i Navigator”) where I can easily view and modify table-structure (including column-definition and indexes) and even run SQL queries. I’ve asked around at the new job, but nobody seems to know of a similar application for DB2 on z/OS.

Can anyone point me in the right direction?

Thanks!

Hello,

We have an index corruption Issue at (HADR environment ) founded into db2diag of primary caused crash , this corruption occurred on primary. I've decided to

1-takeover on standby as no page corruption there and deactivated primary to avoid this corruption moved to standby
2-backup (new primary ) and drop db on old primary
3-restore on old primary (standby) , then working successfully

but doesn't know what the root cause of this page corruption I faced this issue twice during 40 days. My suspect is maybe index not building at true bases, even db2support hadn't got particularity more details they said maybe application code

Is there any way to ensure an index is working fine or not?
As my understanding, there are many flavors of index-related corruption problems, for instance:

Unique index contains duplicates with different RID(s) or same RID(s)
Multiple index entries pointing to the same RID
Index key is out of place (wrong index key order)
Row exists, but index keys do not exist in any or some of the indexes
Index entry pointing to an empty data slot or unused data slot or RID is invalid
Incorrect previous or next index page pointers, incorrect high key or other corruptions on index pages

And if this happens again, is there any different method unless backup and restore?

I found This maybe can be a solution could you please give me your thoughts can i do this as a solution ???

REORG the corrupted indexes or mark the index as bad by …

I have access database that runs 3 business rules and updates a final table in access. The logic is in the module rule mod. I need to loop through 1 million row tables in access and perform procedure logic against the record set. I am thinking before the database gets to big I should process this information on Teradata platform. Somehow convert this access module in a stored procedure if that is possible. Or there might be another way through subqueries to get the final outcome.

Sample Database
Customer Product Orderdate
11111 VIP 01/01/2017
11111 PLANE 01/16/2017
11111 HOTEL 02/05/2017
22222 VIP 01/01/2017
22222 PLANE 02/28/2017
33333 VIP 01/01/2017
33333 VIP 01/06/2017
33333 HOTEL 01/17/2017
44444 VIP 01/01/2017
55555 VIP 01/01/2017
55555 VIP 02/15/2017
66666 VIP 01/01/2015
66666 VIP 01/28/2017
66666 PLANE 01/29/2017
66666 OTHER 02/01/2017

Business Rule 1 - The first product that has to be ordered is the VIP PRODUCT by customer.
If the VIP PRODUCT is not ordered all rules fail.
Business Rule 2 - If VIP PRODUCT was ordered where there any orders placed within 30 days of the first order for each customer.

Final Output - should look like this:
CustomerID CustomerName OrderRuleTest ProductRuleTest OrderDateTest OrderDateFlag
11111 Customer A PASS …

HI,
Using a standard SQL query editor ( like TOAD) , how can I count the total number of tables in a DB2 Database, and also return the count of rows in each table.

The Database is connected via ODBC connection called an DB2ODBC, the Database name is DB2DB.

Thanks

Hi,

How can i disconnect sessions ( idle or active ) from a DB2 database after some period of time.

I would like to know how to do it for idle and for active connections.

The problem is that for some reason the application is not disconnecting the sessions from the database and i would like to be able to disconnect sessions after some period of time. I will like to find out a way to do it for idle and for active sessions. Like two different ways for each type of sessions state.

What i am doing now to solve this problem is rebooting the computer to release all those sessions connections.

Regards,

Joe Echavarria

I have followed instruction for creating /etc/init/db2fmcd. It's still won't restart.

I have tried the following link

http://www-01.ibm.com/support/docview.wss?uid=swg21209001

I still get the following

Gcf module 'fault monitor' is INSTALLED PROPERLY but NOT ALIVE
Gcf module '/opt/ibm/db2/V10.5/lib32/libdb2gcf.so' is INSTALLED PROPERLY but NOT ALIVE

If I run /opt/ibm/db2/V10.5/bin/db2fmcd by itself it just hangs.

Hi,
We are on DB2 9.7 Linux OS.
We have a Stored Procedure SP_CLIENT_PROGRAM which calls a lot of other Stored Procedures and has a number of tables involved in Select and Inserts.

We have a user group "MDUSER" to which we granted execute on the Stored procedure "SP_CLIENT_PROGRAM".
But that didn't do any good to the users under that group, as they apparently needed access on those individual SPs and tables inside SP_CLIENT_PROGRAM.

Is there a way to grant execute on the SP without granting the objects under it and the user be able to execute it successfully?

I need to pull out only the alpha characters from an ID file not numeric values, but this returns the numeric values as well

Please assist have found the following for DB2
SELECT CIN, NATIONAL_ID,FNAME,MNAME,LNAME1,LNAME2
FROM Prodmgr.T_Consumer
WHERE CIN NOT IN (SELECT CIN FROM Prodmgr.T_REPORT_CONSUMER)
and NATIONAL_ID not like '%?%?'
and ( National_ID not in '%A%'or National_ID LIKE '%B%'or National_ID LIKE '%C%'
or National_ID LIKE '%D%'or National_ID LIKE '%E%'or National_ID LIKE '%F%'

Is there a difference bwteen selecting rows in the WHERE clause on in the JOIN clause.

For example,

SELECT t2.*
FROM orderHdr t1
JOIN orderDtl t2 on t2.orderno = t1.orderno
WHERE t1.orderno = 100
AND t2.status = ' '

as opposed to

SELECT t2.*
FROM orderHdr t1
JOIN orderDtl t2 on t2.orderno = t1.orderno AND t2.status = ' '
WHERE t1.orderno = 100

I would think the second method would be faster as I'm thining that join is only to rows where the status is blank.

Thanks for your thoughts,

Rob
