I've created a Tableau workbook that is based off of a SQL query connecting to an Oracle Database. Let's pretend that the query has 2 fields, ID and Stock number. On the Data Source tab one row shows ID = 2040 and the Stock number = 47 but on Sheet 1, ID = 2040 shows a Stock number = 2040. The remote type of the Stock number field on the Data Source tab is "Fixed precision number" and on Sheet 1 it is "Double-precision floating-point number."
For a reason I do not understand the Stock number is equal to the ID for all rows of the data when looking at the data on Sheet 1 (or any other Sheet for that matter). This is incorrect when I look at the Data Source tab or if I use Oracle SQL Developer to run the query. Why and how is this happening in Tableau?
What I've already tried
Using the Stock number field as a Dimension and a Measure
Using "View Data" on Sheet 1 - It shows that the row where ID = 2040 also has a Stock number = 2040
instead of the correct value of 47
My advice is to start a new workbook and take your query right back to basics. Only have a simple select statement and return a few rows.
Then build up from there. You want to get as simple as you can, with no column aliases if you can avoid it.
From there add more complexity to your query, one step at a time so you can pinpoint the exact moment when your query stops working.
I have seen Tableau get confused by data types before, so make sure you check all of the data types that Tableau suggests when you first build your data source. And update them as necessary.
If you can remove or even blur out any sensitive content and show us a picture that would help immenesly. Obviously a picture tells a thousand words.

I have a table in SQL Server that contains document-related data. Data entry in this table is handled from ASP.NET code:
I have to show this table data in PowerBI desktop. With normal Select query I could bind the data in table of Power BI desktop. But along with this table data I have to show one more column IsProcessedBefore which I have to compute for each row.
This column values could be '1' or '0':
1 indicates that this particular Document Number has been processed earlier
0 indicates that this particular Document Number has not been processed earlier.
Output should be shown in Power BI desktop report as shown below.
I am not getting how could I compute this indicator for already existing data.
Whenever a new entry is done in the SQL Server table. It must be reflected same in the PowerBI report along with the computed indicator value.
Please help me with this scenario.
One way that I found is to create another page in same Power BI report, showing the number of times the documents processed using group by query on documentnumber and documentId (Output Shown below). But this is just workaround. Using this approach we will be having two pages. One could check documentnumber from actual table data in below output and refer its count. If its count is greater than 1 that means it is processed earlier.
.
But this workaround does not match up with the exact requirement.
I am working on Excel file to load the data into sql table using SSIS VS2013.
How do I extract the column names into a temptable?
In the image attached,there is the "2017 Marketing Sales - Actual" column in the first row, I want to extract the YYYY from the column name and pass that value to a variable and update the table field with YYYY info.
Can you anyone help me how to do this?
In your Excel Connection Manager, uncheck the "First row has column names" check box. This should allow you to access that first row. You'll need to setup a Data Flow Task using this Excel Connection Manager, followed by a derived column to extract the left 4 characters from that 1st row. Unless you somehow limit the rest of the Excel data source, you'll probably also get a lot of extraneous rows importing into your destination. Might need to do some clean up to get it down to just that year.
I created a pivot table in SQL that has report names along the left side, and hours (00:00, 00:01, etc.) along the top. The values in the table are the number of times each report has been used during that hour over the past three months. I've imported the table into SSRS, and I'm trying to create a heat map of sorts. I want to color the cells darker or lighter across the row based on the number in each cell compared to the value of cells across the row (cell that has the highest value will be the darkest colored).
I've tried following this guide to color the cells, but here the entire row is one field, while I have separate fields for each column. Is there a way to achieve this?
EDIT: Added picture of table design, and preview where coloring is done incorrectly
I understand your problem better now...The function uses the min and max values of a column to determine the range from lightest to darkest, then it probably looks at what fraction of the range your actual value is. In your case where you have each column's data coming from a different cell it'll be a pain unless your columns are fixed and even then it's more trouble than it needs to be.
I would suggest the following.
DON'T PIVOT your data in SQL, we can do that really easily in SSRS, your dataset will be simpler too something like
ReportName Hour UsageCount
ReportA 0 8
ReportA 1 4
ReportC 22 18
and so on...
Create a new report and add a matrix with reportName as the row group and hour as the column group. The data values will be UsageCount.
That's it for the report design, then just set the cells back ground based on your function but this time you can pass in Max(Fields!UsageCount.Value) etc as per the sample.
I've rushed this a bit so it if not clear, let me know and I'll post a clearer solution.
I have a list named Employee Dates, this list contains the columns:
Employee | CPR Completed | CPR Required | ETC
These columns keep going on for all of the training courses required for our employees with alternating columns for completed and required dates. I am using a workflow to calculate all of the required dates of training from the completed dates.
What I desire to do is make another list that will look at ALL of the columns for the required dates and find the soonest ones and populate that list with the soonest dates and from which column it was pulled from.
Any help as to how to approach this? I have been trying to use queries in Access and also some of the custom view settings in SharePoint Designer but no luck so far.
You could try an Excel table (they also have these functions in access if I recall, but I avoid access like a plague). To connect Excel to share point follow the steps in this article:
support.office.com
Ok, now that we are connected you should see all of the columns and values in excel. Next up we need to find the min date (easy) and then get the associated column name (a little harder).
Min Date: The formula should be something along the lines of =min(B1,B3,B5), jut type in =Min( and then CTRL-click on the columns you want to consider for the row. When your done close with ). After wards double click on the square in the bottom right corner and it will do the same logic for all of the rows.
Column Name: A little more difficult, use the min value from the prior column as the lookup value for VlookUp to get the column name. After wards double click on the square in the bottom right corner and it will do the same logic for all of the rows. I'd explain VlookUp, but I'd run out of characters and attention span long before I got to the relevant parts, and excel functions does a fine job of getting you the basics.
Anyway hope that helps,
I am trying to create a couple of reports from data on another Excel worksheet based on the value in a drop down list. I am using the MATCH and INDEX functions and have created Named Ranges of the columns of data. I am able to get the first value I want in the report but none of the others, even though when I debug by evaluating the formula it points to the right cell but still displays #REF! instead of the actual value from the referenced cell.
I'll do my best to make this clear:
In "POST_Data" worksheet I have 4 columns titled Course Name, Course Length, Attendee and Date Attended. Currently I have 33 rows of data (plus the header row) but I need the reports to be dynamic since new data will be added from time to time.
I have created Dynamic Named Ranges of the data using the OFFSET function (e.g. for the Course Name data I have a NameRange called CourseNamesData = OFFSET(POST_Data!$A$2,0,0,COUNTA(POST_Data!$A:$A),1)
In the "DashBoard_and_Data Entry" worksheet I have a two report areas: one to report the Course Name and Date Attended for a specified Attendee (specified by a drop down list in cell C7) and the other report to provide the Attendee Name and Date Attended for a specified Course Name (specified by a drop down list in I7).
In row 8 I report the column that the data belongs to in the POST_Data worksheet
What IS working: When I choose an Attendee from the drop down list in C7, I correctly report the first of the Course Names for this attendee from the data in the POST_Data worksheet. I used the following formula to do so: =INDEX(CourseNamesData,MATCH(C7,AttendeeNamesData,0),B$8)
What is NOT working: The corresponding "Date Attended" data when I use a similar formula as the one that is working. I have: =INDEX(DateAttendedData,MATCH(C7,AttendeeNamesData,0),C$8) but this gives me the #REF! error.
Again, when I try to follow the data that this formula points to, it looks like it is pointing to the correct cell but not showing the result.
Another issue is how to get all the data corresponding to the choice in the drop down and not just the first row. So for example, if I choose Richards, K. from the attendee list and he has attended 4 training courses, I need all 4 to show up, not just the first one.
I appreciate any help or insights on this. If you know of a better way to display the workbook contents, please let me know.
Thanks!
Can you provide a screenshot so that I can better understand the issue?
With regard to your post_data worksheet, you might find it easier to turn the data into a table. You can then point your named range to the column within the table without needing to use the offset function, and your range will update automatically as you add to the table.
I have a entire playlist on my youtube channel devoted to using ranges and tables if you are interested. https://www.youtube.com/playlist?list=PL1nLTDk2QLL9415OPSjIICJs1EeV-HeK3
