OK, first question here so go easy!
Let's start with some quick background - I have been working with Crystal almost daily for the past 15 years to so, so I like to think I am not too much of a dummy.
Today, I have stumbled across a problem I have never seen.
My source data is from SQL Server 2012 Standard.
I have created a view, nothing too complicated. It grabs PartNo and Description from an Inventory Main table. Then a few other columns from other related tables so I can see the data neatly in a single view, so stuff like carton qty (how many units go into 1 carton), height, length, depth.
Now, bear in mind I have done these kinds of views so many times in the past I couldn't even count.
Now, in Crystal Reports 2013, I connect to SQL via OLE using sa credentials, find my view. Pop over to the "Links" tab in the Database Expert, and my columns created from the related tables are not listed! Only PartNo and Description are visible.
I have scratching my head over this for the past few hours & the only thing I can put it down to is some kind of weird Microsoft update.
My SQL view results:
SQL view
What I see in Crystal
Database Expert, Links
the other way to test this is instead of a view or table just add a
command and select * from yourview
the only downside i think would be using sql expression from a command connection.
another option is to
To define the data type in the view... same with dates. does not like
to be converted otherwise will treat it as a string

I have two Databases, one which looks at Financial Year 2018- 2019 and another which will be looking at Financial year 2019-2020.
Now these are Sage Databases so they have a lot of Tables within each of them, the setup of each Database is exactly the same.
Now I had a report which looked at the current financial year no problem, but I didn't realise that they had it set up as the previous financial year would be stored in a separate Database.
I've said "View" within my title, but that's not really what I need as I need whole tables.
So my question is this, is there a construct within SQL that will allow me to create a new datasource of some kind which contains the 12 tables I actually need to populate my report and the data inside these tables be a union of the 12 tables from 18-19 and the 12 tables of 19-20.
I hope that make a least a little sense.
(I would just try and make use of a view, but there's multiple datasets within the report which make use of the joins in slightly different ways)
I have found something I'm a little concerned about. Was trying to get a measure working and had it as a calc column previously so was comparing the 2 different outputs and checking for line by line differences. I picked a good one and investigated. calc column value was zero, measure value was £42. The calc column is correct. So i drilled into my measure to see what i could find. Alarmingly, I found that for a certain field called DocumentStatus the pivot showed it as "LIVE". But if I go to the table in visual studio and find that order the status is "COMPLETED". I have checked and rechecked. There is only 1 order on this table with the right DocumentNo. The pivot seems to think this order is LIVE but the source data definitely shows it as completed. What??? How can this happen?
So strictly speaking the measure is actually calculating correctly because it is seeing the order as live therefore picking the £42 value is correct for that formula. The calc column is correct because it is seeing the order as completed so picking zero as the final value is correct.
It is the fact that the record is being seen as both live and completed that is throwing me. I'm concerned to say the least. This feels like a bug. I have checked and have no other filters in play. I have checked other ways too - like filtering on all orders with a £42 value in a particular field - none of the have a LIVE status. Its almost like that field is misaligned in the background.
Has anyone ever seen this?
TIA
SSAS Tabular; SQL Server 2016, Visual Studio 2017
Edit 5 Jul:
Thanks for your comments. Unfortunately I cannot provide sample data due to strict confidentiality. I have provided 2 screen shots below, both showing the same record - (1) is the view from the excel pivot table that is connected to the ssas tabular data model (2) is the view of the table in Visual Studio (note how the value of the Accrued Income measure in this view is not the same as the AccruedIncome total in the excel pivot table)
I am wondering if this is to do with the way that I have deployed recent edits to the data model. Every time I make a change I am running the deploy & build commands so that I can refresh the excel reports to see if they are working as intended. What I don't know is when I do this am I deploying the metadata only or the metadata and the actual data (several hundred thousand rows on a dozen or so tables)? Is the issue here that the pivot is looking at an older set of data than the dataset visual studio is looking at? When I deploy & build do I then need to process the SSAS tabular object to update the data?
Also note how the DocumentStatus is different in the 2 views.

I'm used to scripting in Python or Matlab, and my first couple hours with SQL have been infuriating. I would like to make a list of columns appear on the screen in any way, shape, or form; but when I use commands like
select *
from "2Second Log.dbo.TagTable.Columns"
I keep getting the error:
Invalid column name '[the first column in my table]'.
even though I never explicitly asked for [the first column in my table], it found it for me. How can you correctly identify the first column name, and then still claim it's invalid!? Babies will be strangled.
This db was generated by Allen Bradley's FactoryTalk software. What I would really like to do is produce an actual list of "TagName" strings...but I get the same error when I try that. If there were a way to actually double click the table and open it up and look at it (like in Matlab), that would be ideal.
Echoing juergen's suggestion in the comment above. It looks like you're running the query on the master database, not the 2Second Log database that actually has your table. (You can tell this by looking at the database in the dropdown in the top left of your screenshot). Two things you can do:
Change the dropdown in the top left to 2Second Log. This will target your query to a different database
Put your database name in brackets as suggested by juergen i.e. select * from [2Second Log].dbo.TagTable
As an side, if you're looking for a good SQL tutorial, I highly recommend the Mode SQL tutorial. It's a fantastic interactive platform to get your SQL feet wet.
always use brackets when names/field have spaces or dashes.
select * from [2Second Log].dbo.TagTable
Here's the general schema for my tables(incomplete)
Employees(**EMPiD**, FirstName, Lastname, cell, name)
Trainers(**TrainerName**, Specialty)
EmployeeTrainingCompleted(**EMPID,TypeTraining,** TrainerName, Score, Comments)
Training(**TypeTraining,PositionTitle**) //this one is fishy, and likely subject to change, but irrelevent to this question
Position(**PositionTitle**,Description,StartingPay)
I am working on an Access 2010 form that will allow the user to select from a combobox the "name" field of a particular employee(which is a calculated field from fname,lname) and view all of the completed training, trainer name, comments, score, etc for that EMPID.
I have completed forms that do this for a single instance of training, but I would like for there to be one form that will dynamically display an indeterminate amount of rows for each employee(because employees have completed a different amount of training courses).
I am new to Microsoft Access and I was wondering if there is an easy way to accomplish this.
Thanks for your input.
While MySQL and Oracle are useful for the database side of things, they will be of no use for the RAD side. Access is really a RAD tool that generally, but by no means always, uses a Jet/ACE database for a back-end ( https://stackoverflow.com/tags/ms-access/info ).
To get a general idea of what you can do with Access, look at the Northwind Sample database, which you will find in New --> Sample Templates --> Northwind in your Access 2010 or if you intend to work with a web deployment, http://blogs.office.com/b/microsoft-access/archive/2010/07/19/northwind-2010-web-database-is-now-available.aspx.
Calling these "databases" is misleading, in that they include a great deal more than you will find in a database. In this case, have a look at the Order Details form under Customers & Orders.
I am not sure about the 2010 version of Northwind, but the earlier versions used to come with a warning that you should disregard any code and just use them for ideas on what you can do with MS Access. For code, consider these books MS Access 2003 - Good book on learning advanced VBA.
I have a database that I just converted the back end to SQL Server using SSMA. I left the front end in MS Access. I only converted the tables and not the queries. It already had some data in it and that moved over just fine.
All was going well until just recently. On opening the database and loading the main form Event Interest it started having problems with the first record of the subform, called Names. The first field in the first record has data sometimes and not others. This is a text field. When data is in the field it puts in random numbers. I believe they may be related to SQL somehow. When there is no data/missing you can select the field and hit the backspace button and the data will appear minus the one character you just errased. I have no idea what is going on.
Any help you can supply I would greatly appreciate it. Thank you in advance.
I am new to SQL Server and I have used older versions of MS Access for a few years.
I am not certain what the problem might be, but these are some considerations that come to mind:
try deleting and recreating your linked tables. Perhaps an update to the table structure (or view, if you're linked to a view) has invalidated some of the metadata stored in the table link in your front end.
does your table have a primary key? If not, you really need one. There really is no such thing as a properly-designed data table in a relational database that is PK-less.
does your table have a timestamp? If not, add one, as this helps Access keep track of whether or not the data has changed on the server.
However, let me add that none of these issues manifest themselves exactly with the symptoms you've described, so they may not help.
