I'm new into AS400 and I got a job where I'm using AS400 and Powerlink (XA) to access and manage big ERP data. And I found a way to access the data through Excel VBA and SQL using the System I Nagivator tables.
My problem is that I can't find the correct Schemas>Tables in Navigator to feed the excel VBA that matches the data that I want in AS400.
Question: let's say I want to find the price for an item, and I want to find the price table in Navigator. Is there a way in AS400 to get the price table name that matches the same table in Navigator ?
This is my first question please let me know if more information is needed.
Please help, thank you!
First a little terminology, AS/400 is an old term, the current name for the Platform and OS that used to be called AS/400 is now IBM i on Power Systems. IBM i is the OS. (that is until IBM changes the name again)
If You Know the Table Name but not the IBM i Object Name
On IBM i, the database is built into the OS and many of the OS objects are in fact database objects. Here is how some of the SQL concepts map to IBM i terms.
SQL IBM i
-------------- ------------------
Schema Library
Table Physical file
Index Logical file
View Logical file
Row Record
Column Field
Unfortunately in IBM i, object names are limited to 10 characters. SQL names on the other hand can be up to 128 characters. You won't find a Physical file named CustomerMaster. DB2 maps that long name to a system name. You can find the system name by querying the catalog like this:
select system_schema_name, system_table_name
from qsys2.systables
where table_name = 'Navigator name'
The column TABLE_NAME will hold the long SQL name of the table, SYSTEM_TABLE_NAME will hold the IBM i object name. Note that long schema names can be mapped to system names as well. The column SCHEMA_NAME holds the long SQL name of the schema while SYSTEM_SCHEMA_NAME holds the IBM i library name. It is uncommon for schema names to be longer than 10 characters, so the two schema name columns are typically the same.
If You Know the Program Name, and Have Access to the Source
This may be obvious to you, but I am putting it here just for completeness. You can look in the source for the files being used, and back track from the screen field to the file.
If You Only Have A Green Screen
You can retrieve the open files for the current job if you have the appropriate authority. If this doesn't work for you, you will have to get help from your system administrator, or someone who does have authority. This will only get you candidate files though, and likely they are logical files. To do this, you are going to have to have authority to view your job, and you will have to know how the system request key is mapped to your keyboard (that is implementation specific, and may be customized, so you will have to check with someone inside your company or your emulator to determine that).
With that behind us, start the green screen program that shows the price field you are looking for. Then press the system request key. If you are configured to allow this, you will get an input line on the bottom of your screen, and the cursor will be positioned to it.
Press Enter.
You should now be in the System Request menu.
Select option 3 and press enter again. You should be in the Display Job screen for your current job.
If this all worked correctly for you, then option 12 will show you the files that your job currently has a lock on. That is, the files that are open for your job. The price field should be in one of them.

Apologies if something similar to the question I'm asking has already been addressed. I'm not even sure how to best frame my question but I haven't been able to find any posts that are obviously germane. I'm hoping someone has some experience with this and might be willing to offer some suggestions. My company has already contracted to have the bulk of our database converted to HTML for ETL purposes and we simply can't afford to double the already barely-manageable costs of this project by adding this additional requirement to the scope.
We have a SQL database from an EMR software vendor that our company has now left. Due to recent economic factors, we just just can't afford to stay with them any longer. When we left this ex-vendor begrudgingly provided us with a backup copy of our SQL database along with copies of all the scanned images our users have uploaded via their application GUI over the years. I was told they stored the uploads as BLOB data but it turns out not. They weren't actually storing the files in the database at all. Instead, they moved the image to a storage location and wrote the ID, DocType, Filename, DirPath and other document information to the Document table of the DB. It makes sense but leaves us in a bind. Mainly because the filename appears to have been randomly generated at upload. So we now have 50,000 image files with unintelligible filenames stored in a date-based folder structure with no way to correlate any of them with the patients to whom they belong. A couple of examples are as follows:
/root/2020/05102019/69353829-e46b-47e7-ab56-a1762424f0dd.pdf
/root/2014/09282017/385ba21d-e108-4cbb-9287-91110c16edb0.jpg
I compiled a list of attribs so I can make any of them available to the transform. I pulled:
SELECT * FROM document d
JOIN patients p ON d.PatientId = p.pid
JOIN users u ON d.PatientId = u.uid
WHERE u.UserType = '3' AND d.fileformat is NOT NULL AND d.dirpath LIKE 'm%'
ORDER BY u.ulname;
This gave me all patient and document attribs resulting in a list with 197 columns. The challenge is the new EMR vendor can only import these files if all the files for each patient are in a dedicated folder at the patient level so I need the files in a new folder structure. I am trying to do it without abandoning things like PatientID, Scan Date, Description (the customName column), Scanned By, and a possibly a couple other points.
I'll probably end up making the file name something like a concat of customName+docID for identification purposes. Then I'll just need to get the files in something like a /Patient/Docs.extension folder structure.
I went ahead and flattened all the files into a single folder figuring that would make it easier to manipulate. I batched them out like so:
md "D:\OneDrive\Documents\Assets\eClinicalworks\PID\FTP\mobiledoc\Documents\All\"
cd /d "D:\OneDrive\Documents\Assets\eClinicalworks\PID\FTP\mobiledoc\Documents\"
for /r %d in (*) do copy "%d" "D:\OneDrive\Documents\Assets\eClinicalworks\PID\FTP\mobiledoc\Documents\All\"
Now I have them all together.
Screenshot
I still have to figure out how to get them into the new folder structure by patient though.
Just to have it mentioned, I was originally considering using SQL so I could recreate the files and assign the desired attribs as file attribs in one step.
To answer the question asked about the HTML conversion, we have tons of Progress Notes, Doctors Notes, Prescriptions, etc in the database. The only way to get them to the new EMR is to export them to HTML and group them at the patient level so the new vendor can import them.
Honestly, after having to wrestle with all this garbage, I would prefer to avoid this situation in the future by refusing to upload them to the new EMR at all. Instead, just put all these documents on OUR file server and give the new EMR a hyper-link to insert into each patient's patient record that would open all the patient files. The new EMR is browser-based so it could be feasible but I doubt I'll be able to get them to write files to our file server moving forward so doing so would likely just end up making the end-user experience more disjointed.
I don't think your contractors did anything wrong tbh. Taking uploaded files with all their problem characters/duplicated names (got more than one patient called JohnSmith.jpg?) etc and renaming them to a GUID so they can coexist alongside other images without overwriting them is a) sensible and b) what I would do.
I also wouldn't store images inside a database as then the only thing you can do with them is get them out again; something you have to do every time you want to do anything with them. Being able to map an images folder to a url on your web server and then send html using just the file name means that the web server can sever the image without having to pull it out of the db; the db doesn't have to involve itself in pointless IO.
The way to correlate these images with the patients to whom they belong is done by the database. Somewhere else in the db structure will be eg a Patient record with a DocumentId column that links to this document record or a PatientDocuments table that has PatientId/DocumentId pairs.
If there is not, then storing the document bytes in the db won't have helped relate them to the patient, because this relation is not about where the bytes of an image are, it's about what other data was stored to make for a usable system. As it stands your thoughts on the matter, of uploading tens of thousands of images into a db just so you can... er.. get them all out again, would seem to indicate you haven't yet fully grasped the reasons behind why your contractors did what they did.
Because you're under the impression that you can do this, you seem to know how the db relates a document to a patient (if it doesn't then your proposed process will fail) and as such you can arrange for a suitable renaming process without needing to move the image data anywhere. In essence, you're failing to see that a file system storing file data against unique paths is no different to a database table storing file data against unique ids. Your database tables for documents clearly thus links to your file system/file system can be viewed as an extension to the documents table. You need the other tables in the db to make sense of the files, but you need the other tables in a db to make sense of any table in a db. These are key concepts of modelling related data
I don't recommend you undertake the process you propose, but I'm sure that won't dissuade. Consider then (because you didn't really post any details we can work with) this assumed scenario:
Patients
Name,DocumentId
John Smith,1
Jane Doe,2
Documents
Id,FilePath
1,'/root/2020/05102019/69353829-e46b-47e7-ab56-a1762424f0dd.pdf'
2,'/root/2014/09282017/385ba21d-e108-4cbb-9287-91110c16edb0.jpg'
SELECT CONCAT('REN ', d.filePath, ' "', p.Name, RIGHT(d.filePath, 4), '"')
FROM
Patients p
INNER JOIN Documents d ON p.DocumentId = d.DocumentId
The results of the query will essentially be a batch file full of rename commands that renames all the files into a single folder, organized by patient name.
And now all your multiple patients with the same names will overwrite each other and everything will end up in a mess
It also makes my point for me about "don't store files in the db" - look how easy it is to manipulate files when they're in a file system, using existing commands that understand filesystems and files and do things like rename files, or extract exif data, rotate, resize and print... if all those images were in your db the only thing you could do with them, is get them out again; sqlserver cannot rotate, resize, print etc BLOB data but there are thousands of tools out there that understand files and can convert them - those tools cannot understand your db so putting files into a db saddles you with the problem that they become useless until dug out again
Your contractors may not have been so daft as you think; pause a moment before you set about hacking apart all they did, and question whether your driver for doing so is actually correct. If Jane from reception needs to see a picture of John Smith with drivers license XY1234 to ID him, don't provide her with a shared drive full of everyone's pictures, and let her double click, drag and accidentally delete her way around the file system. Provide her with an app that looks in the db, gets the unintelligible but helpfully unique filename off disk and opens it for her to view. And make the file system read only to everyone other than the app, so that users can't break things
I have a database running now that has had all data in the "leads column" / "phone number row" removed. I have created an updated csv file that has most of the phone numbers present in addition to the client name, email and address.
How can I import the phone numbers in the phone numbers row based on matching the client name, email or address data, without affected any other columns or rows other than the phone numbers row?
This sounds like the perfect fit for an SSIS package! (this is assuming you are referring to SQL Server...since you didnt list an RDBMS it is just a guess)
Some SSIS package basics materials:

SSIS is basically an ETL package development tool used with SQL Server that has countless options for moving data around. You would only need on data flow task inside of SSIS to accomplish what you are searching for. I highly recommend reading up on some of the content above and giving it a shot!
I'm a bit of a newbie with the workings of phpmyadmin. I have a database and now there are 2 parts within it - the original tables jos_ and the same again but with a different prefix, say let's ****_ that will be the finished database.
This has come about because I am upgrading my Joomla 1.5 site to 2.5. I used a migration tool for the bulk of the new database but one particular piece of information did not transfer because the new database has a different structure.
I want to copy the entire contents of jos_content, attribs, keyref= across to ****_content, metadata, "xreference"."VALUE" if that makes sense. This will save manually typing in the information contained within 1000s of articles.
jos_content, attribs currently contains
show_title=
link_titles=
show_intro=
show_section=
link_section=
show_category=
link_category=
show_vote=
show_author=
show_create_date=
show_modify_date=
show_pdf_icon=
show_print_icon=
show_email_icon=
language=
keyref=41.126815,0.732623
readmore=
****_content, metadata currently contains
{"robots":"all","author":""}
but I want it to end up like this
{"robots":"","author":"","rights":"","xreference":"41.126815,0.732623","marker":""}
Could anyone tell me the SQL string that I would need to run to achieve this please?
If it makes any difference I have manually changed about 300 of these articles already and thought there must be a better way.
Edit: Being nervous of trying this I would like to try and find the exact syntax (if that's the right word) for the SQL Query to run.
The value I want to extract from the source table is just, and only, the numbers next to keyref= and I want them to turn up in the destination table prefixed by "xreference". - so it shows "xreference"."VALUE" with VALUE being the required numbers. There is also an entry - ,"marker":"" that is in the destination table so I guess the Query needs to produce that as well?
Sorry for labouring this but if I get it wrong, maybe by guessing what to put, I don't really have the knowledge to put it all right again....
Thanks.

I am reviewing a coworkers sqlgen job and I am unable to figure out what this means in the table generation settings.
Specify number of rows by: "Same as mapped data"
My coworker has this selected on each table, I just need to know what is meant by this I have looked through documentation and been unable to find a definition for this.
I am on version 2 at the moment. Probably not the best question but I need an answer and he is gone for a long period of time and our data is not working correctly with this tool.
The "Same as mapped data" option is only available when you're using an existing table or view as a data source - it just means that the generator will insert all the rows from the source table or view. The other options are:
Numeric value - a set number of rows
Proportion of table - a proportion of the source table/view
Generation time - as much data as the tool can generate in a set time
There's a little more about using an existing table/view as a data source here on the website, but it doesn't have much else useful in it.
Hi does any one know how to check if a given DB object (Table/View/SP/Function) is used inside Oracle.
For example to check if the table "A" is used in any SP/Function or View definitions. I am trying to cleanup unused objects in the database.
I tried the query select * from all_source WHERE TEXT like '%A%' (A is the table name). Do you thing it is safe to assume it is not being used if it does not return any results?
From this ASKTOM question:
You'll have to enable auditing and then come back in 3 months to see.
We don't track this information by default -- also, even with auditing, it may be very
possible to have an object that is INDIRECTLY accessed (eg: via a foreign key for
example) that won't show up.
You can try USER_DEPENDENCIES but that won't tell you about objects referenced by code in
client apps or via dynamic sql
There's code in the thread for checking ALL_SOURCE, but it's highlighted that this isn't a silver bullet.
