MSSQL COALESCE function with multiple non null values

Asked 2021-Apr-08 at 18:50

I am trying to get data (T_Stamp, Destination, Weight, Line) from two tables using variable time intervals and a destination selection. This is going into an Ignition SCADA. My SQL code below works for most cases except when there are entries into both tables with the same timestamp. In those cases it shows only the data from table A. This is giving me results with the incorrect destination. I understand that the COALESCE function is returning the first Non-null value, but I don't know how else to write this logic.

I suspect what you want is something like the following, which uses a UNION instead of a JOIN.

You code must be called from a view, so there is the "request context".

You should also have a look at the official documentation:

QUESTION

Script returning error: "Get-Content : An object at the specified path ... does not exist, or has been filtered by the -Include or -Exclude parameter

Asked 2021-Feb-16 at 17:46

EDIT I think I now know what the issue is - The copy numbers are not REALLY part of the filename. Therefore, when the array pulls it and then is used to get the match info, the file as it is in the array does not exist, only the file name with no copy number.

I tried writing a rename script but the same issue exists... only the few files I manually renamed (so they don't contain copy numbers) were renamed (successfully) by the script. All others are shown not to exist.

How can I get around this? I really do not want to manually work with 23000+ files. I am drawing a blank..

HELP PLEASE

I am trying to narrow down a folder full of emails (copies) with the same name "SCADA Alert.eml", "SCADA Alert[1].eml"...[23110], based on contents. And delete the emails from the folder that meet specific content criteria.

When I run it I keep getting the error in the subject line above. It only sees the first file and the rest it says do not exist...

The script reads through the folder, creates an array of names (does this correctly). Then creates an variable, $email, and assigns the content of that file. for each $filename in the array. (this is where is breaks)

Then is should match the specific string I am looking for to the content of the $email var and return true or false. If true I want it to remove the email, $filename, from the folder.

Thus narrowing down the email I have to review. Any help here would be greatly appreciated.

This is what I have so far... (Folder is in the root of C:)

QUESTION

Is there a way to automatically insert rows that are updated on a linked server?

Asked 2021-Jan-28 at 04:48

The local server (SCADA System) uses SQL Server, and the linked server (ERP System) uses Oracle.

The current situation is as follows:

The ERP system has a table on its server to which all batch orders are consistently updated. I have access to that table, but I cannot manipulate / configure anything from the ERP side. Any configuration / querying must be done on the local server.

I tried querying rows directly from the ERP table, but for some reason that causes a ~30s delay. I then created a local table and inserted all rows from the ERP table, to see if there still would be a delay if I'm querying from the new local table. No delays there. So I figured if I could keep the local table updated as with the ERP table, I just need to use the local table.

So my question is, without the ability to configure / manipulate the ERP side, is there a way to insert all new rows that are updated on the ERP table to our local table?

...

ANSWER

Answered 2021-Jan-28 at 04:04

Typically DBAs for ERP systems don't like to change the main ERP model schema because it creates more objects to deal with during application upgrades - vanilla application upgrades are usually preferred.

What they do sometimes tolerate is to create triggers on the ERP table into another table (your design) inside another Oracle schema which you can manipulate at will.

From this table, you can decide to pull the data into MSSQL through your linked server setting flags as you go or deleting old data so your data fetch is minimized for each call. Typically calling a stored procedure in the new Oracle Schema to perform table updates or deletions seems to work better because linked servers are very slow when pulling data over to the MSSQL side to work on them.

Another alternative (which is much faster than using a linkedServer) is to use a Windows service or a scheduled script(ex VBS) on a windows server to talk to both Oracle and MSSQL to achieve the same objective. This could be done on the original table directly or in the new one. You would have figure out your polling intervals depending on your near-to-realtime requirements.

Downloading file with a space in filename using ftplib

I'm downloading two files from a C-More industrial HMI FTP server. I don't know what OS the HMI is running but I suspect that its FTP server has some quirks.

It's because when the object db.schema.sqlt_table_1 doesn't exist the statement fails. It doesn't matter if the statement won't run, the batch must still be valid.

The statement @VAR = (SELECT 1.0 FROM db.schema.sqlt_table_1); isn't even valid though. You would be better off with this:

There are a number of errors in your control.

You must override the destructor, you must implement handlers for WM_SETFOCUS and WM_KILLFOCUS, you should not invalidate from mouse click event, you should override Click() instead of using OnClick, the Paint procedure should use Width-1 and Height-1, no need to override CreateParams because it is already done in base class.

I believe your goal as follows.

You want to retrieve the values of node-id, trading-date, trading-period and generation from the XML data in your question using Google Apps Script.
You want to put the retrieved values to the Spreadsheet.

Modification points:

In your XML data,
- scada-response is the child of soapenv:Body.
- node is the children of scada-response.
- trading-date is the child of node.
- trading-period is the child of trading-date.
- generation is the child of time-stamp.
In your script, var entries = []; is the 1 dimensional array by entries.push(id, new Date(td), tp, mw); in the loop.
- In this case, I think that it is required to put the values of id, new Date(td), tp, mw to entries as one dimensional array.

When above points are reflected to your script, it becomes as follows.
