Lose data types after model saving

Hi all.
I try to import model from erwin 7.3 in data modeler Version 3.0.0.665
after import i have this log:
Oracle SQL Developer Data Modeler 3.0.0.665
Oracle SQL Developer Data Modeler Import Log
Date and Time: 2011-09-20 16:31:22 MSD
Design Name: DPO
Import Finished
Errors: 0
Warnings: 0
i receive similar model as erwin-model. but afeter saving and reopening almost all datatype set as UNKNOWN. what`s wrong?
i try change type for one column from UNKNOWN to NUMBER and again save/reopen. this change was saving.
how i can save source datatypes after import model?

Hello,
I have no definitive idea as to why you are losing the dataypes, though I suspect it has to do with setting the Design Rules under the Tools option.
The suggestion I want to make is that you generate the DDL from Erwin and and import this and save, all data types should save, they have for me. Also Have found the DDL import to be the most reliable along with importing from Oracle Designer and Oracle database data dictionaries.
If you have logical objects you want to transfer over then I would advise export Erwin to Oracle Designer and import to SQL Data Modeler.
If you go through the threads on this forum you are no alone in finding issues with Erwin import.
Hope that helps.

Local Dictionary Simple Data Types - RFC Model

Hi,
can somebody help out with this error message:
com.sap.tc.webdynpro.services.exceptions.WDTypeNotFoundException: type com.global.wdschulung3.types.String could not be loaded: com.sap.dictionary.runtime.DdException:

is it something to do with the JCO Connection?
I have checked in the WebDynpro Content Admin - and I don't get a green or red Status Symbol - in fact it's just grey - and buttons for "create JCO Connection" ars disabled
thanx for help,
matthias

Hi Bhavik,
thanks for the links - now i configured the sld supplier in visual admin tool and it looks good. Connection test is successful.
Now I was also able to create the JCO Connection in webdynpro content administrator for wd_model_dest and wd_metadata_dest - looks good, and I get a green icon.
Unfortunately testing the jco-connection still fails... I get this error message:

Somebody experienced this before?
thanx once more,

URGENT HELP NEEDED!!! No data connectivity after a while, weird errors

I am using T-Mobile's regular prepaid web plan and Wi-Fi just fine, no need for BIS, Rich Email, or BBM (SMS and MMS is just fine). All I ever use are apps that SPECIFICALLY state that they work over standard TCP/IP and Wi-Fi. The problem is, after some time, the apps that one worked over regular data connections and MMS don't connect anymore. Even though the apps said that no BIS is needed, they can't access data. Even RIM's own Facebook app, which claims to work over Wi-Fi (and does) loses data connectivity after a day or so without a full reboot. The only thing that works is the BlackBerry Browser, which still connects to the internet. Along with the apps failing to work, MMS messages also can't be sent.
Rebooting the phone by a battery pull or alt-shift-delete allows the apps and MMS to work, which after a day (sometimes even shorter) stops working again.
Here's what I've done so far:
- Checked and made sure that all permissions for data access
- Checked that my APN settings are correct: epc.tmobile.com
- Checked my Wi-Fi router for connectivity
- Called T-Mobile tech support for help, wiped my phone upon their instruction
- Reinstalled my apps and contacts, T-Mobile sent me new service books
Still the SAME THING with apps and MMS not working after a while. I've narrowed it down to entries in the event log that show up as this, which shows up seconds before my apps and MMS stop working:
a net.rim.hrtRT - PUpI - 9/23 17:06:58
a net.rim.hrtRT - EPdp 0x3 - 9/23 17:06:58
a net.rim.tunnel - Clos-blackberry.net - 9/23 17:06:58
a net.rim.hrtRT - CClG 0x2 - 9/23 17:06:58
W net.rim.hrtRT - XMax - 9/23 17:06:58
W net.rim.hrtRT - XBad - 9/23 17:06:58
E net.rim.mdp - TEma - 9/23 17:06:58
W net.rim.mdp - TDtm - 9/23 17:06:58
i net.rim.mdp - TTex - 9/23 17:06:58
Can any experts or developers tell me what these Warnings and Errors mean? I am pretty sure that whatever "net.rim.mdp" and "net.rim.hrtRT" is doing isn't good.

anyone care to help???
Also, on the 18th I wiped my phone again, and three days later (longest time with no mdp error) the same error occurred in the event log, no internet connectivity afterwards on Wi-Fi or Mobile Network...

Crystal reports converting varchar 254 to memo data type

Hi All,
We are still using Seagate Crystal Reports 7.5 for some of our reporting. I have a problem that hopefully someone can help with. One of our connections is to ODBC- AR System ODBC Data Source.
In that data source there are fields defined as varchar 254 (confirmed by DBA),
But Seagate is calling them memo fields- which is causing problems since you canu2019t use memos in selection criteria or formulas.
This happened after the field names were renamed. I noticed when the newly named fields were not showing as an option to map the old name fields to- because by default it looks for same data type, after unchecking same data type option the fields showed for mapping but wrong data type makes them useless. I canu2019t even convert them to string with formula field.
Any input would be greatly appreciated.
Thanks-

Hi,
Yup, this was a problem with versions prior to 10. If a field was longer than 254 characters, Crystal handled them like Memos and you cannot use them in formulas.
The only suggestion I can offer would be to upgrade. Crystal can now use memos in formulas and no longer has a 254 character limit on strings. So your charcter fields will remain as charater and not changed to Memos.
Good luck,
Brian

Problem in creating data type

hi..
i've problem in creating data type in xi after importing idoc from the R/3 sender
plz tell me the basic steps for creating data type in the receiver i.e xi.....
thanks in advance

Hi,
You don't need to create a data type after importing the IDOC.
Idoc itself acts as message type and message interface.
check this for creating a data type..

Scripting Crash- "Create from Data Type" on Typedef Enum

I just encountered a crash that I can duplicate in both LabVIEW 2013 and 2012 (student).
Attached is a project that contains the code I used on 2012. Run the target VI.
(I can get the project I had in 2013, if needed, sometime next week)
Basic steps:
Create a type def enum
Place it on a VI
Use scripting to get ahold of the Control Terminal and get the data type
"Create from Data Type"

Haha, I saved your code and ran it while I still had another project open... didn't really think that one through. Thank you, Auto-save.
So it looks like the crash happens at the Create node. I can get rid of the crash by removing the Type Def link from the enum.
I'm not at all an expert in scripting and have only used it a few times. Could a workaround be to get a reference to all of the Controls on the FP and copy the Control with the same Label "Enum" (instead of loading the terminal and creaing a new terminal)? Maybe creating a typedef by data type is what's causing the crash, but copying an already existing control will work.

Core data: Versioned model migration with change in existing attribute data types.

Hi ,
I want to upgrade my ios app with app store version with enhancement of new functionality related to core data features in the app.
-In new upgarde version, I want to change data types of attribute which is already present in core data model of existing app store version.
e.g.In Version 1.0 ,Attribute "date" datatype is "NSDate", New change required to change datatype "NSDate" to "NSString" with new version model.
I followed Lightwaight migration, but as per documentation , Lightwaigh migration not support for change data type of any existing attribute/entity of core data model.
Please suggest optimized solution for migration of database along with change in data type of exsiting attribute of the entity in core data.
If required in further info ,please ask.
Thanks in advances.
Regards,
Laxmikant

More Info: The two entries are actually pointing to the same object. If I save the context and restart, I only have one entry (I can also see this by looking at the XML store).
It seems that the NSTableView is getting messed up somehow after the FetchRequest. Still stumped.

Why has my ipad lost connectivity to the AT&T cellular data network after upgrading to iOS 8.1.2? My iPad is model #MD367LL/A, 32 GB WIFI + Cellular, about 2-1/2 years old.

Why has my ipad lost connectivity to the AT&T cellular data network after upgrading to iOS 8.1.2? My iPad is model #MD367LL/A, 32 GB WIFI + Cellular, about 2-1/2 years old. It;s been working perfectly up until now. I have no problem on my home WIFI, or through personal hotspot working through my iPhone 5.
I have worked with AT&T, replaced the SIM card with a new one, and done a backup/restore to factory settings, all with the same result that when I turn Cellular
Data on, with or without Enable LTE, it goes into "searching" mode, or reports "no service". My iPhone 5 works perfectly on iOS 8.1.2, on Cellular. I've browsed the blogs and have tried Apple's suggested fix, all to no result.
Oddly enough, every once in a while I do get connected to the network for a short ime (minutes), but it always returns to "searching".
I've filed a report with Apple, along with a request that they contact me, but no results yet.
Help? (and thank you).

Hello razmee209. Thank you for your response. I spent the better part of yesterday working with Apple Support. They tried their best, to include backing up photos to my HP laptop, backing up the iPad to iCloud, then resetting the iPad in total. Same problem. I restored from the cloud to recover my apps, same problem.
AT&T installed a new sim card - same problem. I spent time with AT&T Support yesterday, too. In both cases, (Apple and AT&T) the support techs who worked with me were extremely polite, courteous and helpful to the best of their abilities, but I think the problem lies deeper, and nobody at Apple is admitting they have a problem with iOS 8, that I'm aware of.
I didn't have this issue before I upgraded to iOS 8.1.2.
Everything else with the iPad works fine: WIFI, Personal Hotspot, email, all my apps, etc.
In browsing the web for this issue I see that many other folks have the same problem. I filed a report with Apple this morning, requesting that they contact me, but no word yet. I was going to go to iPhone 6, and had been considering the iPad Air 2, but I see reports of this problem with those units as well.
At this point I don't think I'll be spending any more money with Apple, at least not till this issue is resolved.
Thanks again for your response and suggestions.

4.0 EA1 - Data Modeler does not show columns data types correctly

Data Modeler shows all columns data types as 'unknown'.

Hi,
you need to check "system data types" directory and it contents. Its default location in SQL Developer is sqldeveloper\sqldeveloper\extensions\oracle.datamodeler\types
Check "Preferences>Data Modeler>Default system data types directory" setting. If it's empty then copy defaultdomains.xml from previous installation to directory above.
If it's not empty then you need to copy types.xml and defaultRDBMSSites.xml from default location to directory set as "Default system data types directory".

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:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> I need to select from a dynamic column name and save the result in a variable, but seem to be having trouble with the values being fed to sp_executesql <<
This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?

Data Modeler Logical Data Type confusion!

I don't get it.
When defining a logical model, I want to assign data types to the attributes in my model.
I understand a logical datatype like money, and that a logical datatype might be implemented differently in different databases. The concept makes perfect sense to me.
I pick a datatype from the Logical Types.
It ignores the logical datatype that I picked and puts in another datatype instead. I'm guessing that it's a physical mapping. I would understand the logical-to-relational mapper doing that , but I don't understand it happening at this point in the model life cycle.
Let's say I pick Money. It puts Double into the logical datatype, not money.
If I pick Date or DateTime, it puts Date into the logical datatype, so what is the point of giving me two types to pick from?
Seems kind of wonky.

David,
We will publish soon a document on how the data types work.
If you go to tools, Types administration you will see that a logical type is mapped to a native type and a native type is mapped to a logical type.
The logical type MONEY is mapped to DOUBLE for Oracle.
Types and domain files can be customised.
One could argue that the logical name MONEY should show up and not the native name. Showing the native name has the benifit that you see what the logical type is mapped to. Both approaches could have their supporters, no?
Kind regards,

Physical Model Data Type Issue

Hi,
I have created ware house tables using E-business suite tables for general ledger model and exported into physical model. I could see all my keys/IDs which were numbers have been converted into decimal.
Ex: journal_id in my oracle table is number (ex:1234). But when I exported into OBIEE and used view data option. All the IDs(data type number) data is showing as decimal format (1234.00).
Ex: If I want to see data for check number in answers, then it is showing as 112456.00 instead of 112456.
Please anyone had this kind of issue. how to resolve?
Is there any default setting which is causing this problem.how to find?
OBIEE version : 10.1.3.2
Appreciate your help.

Hi Sandeep,
When I opened the rpd in offline mode, it is saying the repository can only be opened as Read-Only. I clicked Yes for this and entered admin user name and password. But in Physical model, when I right clicked any table, I couldnt see find any place to modify. I tried with properties also. I am not able change data type as it read-only. How to do it in offline?
FYI,
I opened rpd when OC4J was stopped. Aslo I opened when OC4J is running. But both times I am not able to change datat type.
Thanks!!

Data change after call xml transformation for RAW data type

Hi,
Can someone explain what is workarround or any help for below problem
when call transformation is called for usr02 records, after xml string is generated is showing different data for RAW data type for example content of fields BCODE,PASSCODE etc get convert into different data
for example: content of BCODE fields before xml transformation say -7F8087472FB996E5
after xml transformation it display as f4CHRy+5luU=
why is this so happening? is this known behaviour after xml transformation or it is bug in xml transformation?
thanks in advance.
Regards,
John.

Hi,
I think this is because RAW data is BASE64 encoded when using CALL TRANSFORMATION.
Old post, but did you ever find a way to change that?
Thanks

Data types model

I want to ask you about data types model in SQLDDM. Can anybody of you to explain me what about are all links between structured types, which I can to use, or when i get more information about it ? Thanks.

Hi,
you can find explanation here Data Modeler Concepts and Usage
Well, cardinality as it's shown there is not supported.
If you hover the mouse over buttons you'll get hints what they are used for.
Here is a more real picture:
1) red line is inheritance
2) blue line with diamond at one end and arrow at other end represent a reference (order_typ has a reference to a customer) or collection of references ( car is made by parts)
3) blue line with filled diamond represent a containment of a structured type (customer_typ has a cust_address_typ embedded into it) or a collection of embedded types (a person can have several addresses)
In relational model you can set 'View details" to "Expand complex types":
and you'll get details about used complex types:
