I have following data from my database:
+------+-----------+-------------+---------------+
| ID | SomeValue | SomeDate | SomeOtherDate |
+------+-----------+-------------+---------------+
| 123 | 12345 | 01.01.2017 | 01.01.2018 |
| 123 | 54321 | 01.01.2017 | 01.01.2019 |
| 123 | 25314 | 01.01.2017 | 01.01.2020 |
+------+-----------+-------------+---------------+
I want the following format in Crystal Reports:
+------+---------------+---------------+---------------+
| ID | SomeValue2018 | SomeValue2019 | SomeValue2020 |
+------+---------------+---------------+---------------+
| 123 | 12345 | 54321 | 25314 |
+------+---------------+---------------+---------------+
How can I do this, if it's even possible? I've tried multiple examples but cant seem to make it work. I was successfully able to make the headings.
It is difficult to make Crystal Reports evaluate things horizontally. The entire system is designed to evaluate vertically. (Things on the top of a report are evaluated before things below them.)
However you might be able to get a CrossTab to do this. First you'd want to make a new Forumla field for your columns. It would be structured something like:
"SomeValue" + Year({#SomeOtherDate})
When you design the crosstab, you'll want to set ID as the Row, your new formula from above as the Column, and the Summarized Field will be SomeValue. You'll also want to suppress the Grand Totals in the Customize Style.

I have a table which has multiple payload values in separate rows. I want to combine those rows into a single row to have all the data together. Table looks something like this.
+------------+--------------+------+----+----+----+----+
| Date | Time | User | D1 | D2 | D3 | D4 |
+------------+--------------+------+----+----+----+----+
| 2020-04-15 | 05:39:45 UTC | A | 2 | | | |
| 2020-04-15 | 05:39:45 UTC | A | | 5 | | |
| 2020-04-15 | 05:39:45 UTC | A | | | 8 | |
| 2020-04-15 | 05:39:45 UTC | A | | | | 7 |
+------------+--------------+------+----+----+----+----+
And I want to convert it to something like this.
+------------+--------------+------+----+----+----+----+
| Date | Time | User | D1 | D2 | D3 | D4 |
+------------+--------------+------+----+----+----+----+
| 2020-04-15 | 05:39:45 UTC | A | 2 | 5 | 8 | 7 |

I tried "set" and "aggregate" but they didn't work as I wanted them to and I am not sure how to go forward.
Any help would be appreciated.
Thanks.
tl;dr:
use fill() function to fill all empty values within each d1-d4 columns in the wanted group (AKA - the columns date+time+user) then dedup\aggregate to your heart's content.
long version
So the quickest way to do this is by using a window-function called "fill()".
What this function does for each given field in a column, it tells it:
"Look down. look up. find the closest non-empty value, and copy it!"
you can ofcourse limit it's sight (look only 3 rows above, for example) but for this example, don't need the limitation. so your fill function will look like this:
FILL($col, -1, -1)
So the "$col" will reference all the chosen columns. the "-1" says "unlimited sight".
finally, the "~" says "from column D1 to column D4".
So, function will look like this:
.
Which in turn will make your columns look like this:
.
Now you can use the "dedup" transformation to remove any duplications, and only 1 copy of each "group" will remain.
Alternatively, if you still want to use "group by", you can do that aswell.
Hope this helps =]
p.s
There are more ways to do this - which entails using the "pivot" transformation, and array unnesting. But in the process you'll lose your columns' names, and will need to rename them.
I suspect this question is already well-answered but perhaps due to limited SQL vocabulary I have not managed to find what I need. I have a database with many code:description mappings in a single 'parameter' table. I would like to define a query or procedure to return the descriptions for all (or an arbitrary list of) coded values in a given 'content' table with their descriptions from the parameter table. I don't want to alter the original data, I just want to display friendly results.
Is there a standard way to do this?
Can it be accomplished with SELECT or are other statements required?
Here is a sample query for a single coded field:
SELECT TOP (5)
newid() as id,
B.BRIDGE_STATUS,
P.SHORTDESC
FROM
BRIDGE B
LEFT JOIN PARAMTRS P ON P.TABLE_NAME = 'BRIDGE'
AND P.FIELD_NAME = 'BRIDGE_STATUS'
AND P.PARMVALUE = B.BRIDGE_STATUS
ORDER BY
id
I want to produce 'decoded' results like:
| id | BRIDGE_STATUS |
|--------------------------------------|------------ |
| BABCEC1E-5FE2-46FA-9763-000131F2F688 | Active |
| 758F5201-4742-43C6-8550-000571875265 | Active |
| 5E51634C-4DD9-4B0A-BBF5-00087DF71C8B | Active |
| 0A4EA521-DE70-4D04-93B8-000CD12B7F55 | Inactive |
| 815C6C66-8995-4893-9A1B-000F00F839A4 | Proposed |
Rather than original, coded data like:
| id | BRIDGE_STATUS |
|--------------------------------------|---------------|
| F50214D7-F726-4996-9C0C-00021BD681A4 | 3 |
| 4F173E40-54DC-495E-9B84-000B446F09C3 | 3 |
| F9C216CD-0453-434B-AFA0-000C39EFA0FB | 3 |
| 5D09554E-201D-4208-A786-000C537759A1 | 1 |
| F0BDB9A4-E796-4786-8781-000FC60E200C | 4 |
but for an arbitrary number of columns.
I got two columns list like this
+----+-------+
| Nr | Name |
+----+-------+
| 1 | Alice |
| 2 | Bob |
| 3 | Joe |
| 4 | Ann |
| 5 | Jane |
+----+-------+
And would like to generate a random name from this list.
For now I am only able to randomly select a number and then manually pick out the corresponding name - using this function =RANDBETWEEN(A2;A10) How can I pick out the name instead?
Assuming that the data of your table are in cells E7:F11 the following code can do what you need:
=VLOOKUP(RANDBETWEEN(1;5);E7:F11;2)
Further, in case you need to create a random permutation of the names you may also use the Calc extension Permutate at https://sourceforge.net/projects/permutate/.
Hope that helps.
Assuming your data is with Nr in A1 I suggest:
=INDEX(B$2:B$6;RANDBETWEEN(1;5))
then there is no need for the Nr column in making the selection.
I have a list of survey results that looks similar to the following:
| Email | Question 1 | Question 2 |
| ----------------- | ---------- | ---------- |
| test#example.com | Always | Sometimes |
| test2#example.com | Always | Always |
| test3#example.com | Sometimes | Never |
Question 1 and Question 2 (and a few others) have the same discrete set of values (from a dropdown list on the survey).
I want to show the data in the following format in Tableau (a table is fine, but a heatmap or highlight table would be best):
| | Always | Sometimes | Never |
| ---------- | ------ | --------- | ----- |
| Question 1 | 2 | 1 | 0 |
| Question 2 | 1 | 1 | 1 |
How can I achieve this? I've tried various combinations of rows and columns and I just can't seem to get close to this layout. Do I need to use a calculated value?
As far as I know - it is not natively possible with Tableau, because what you have is kind of a pivot table.
What you can do is unpivot the whole table as explained here https://stackoverflow.com/a/20543651/5130012, then you can load the data into Tableau and create the table you want.
I did some dummy data and tried it.
That's my "unpivoted" table:
Row,Column,Value
test,q1,always
test,q2,sometimes
test1,q1,sometimes
test1,q2,never
test10,q1,always
test10,q2,always
test11,q1,sometimes
test11,q2,never
And that's how it looks in Tableau:
I'm creating a crosstab report showing the survey history for gopher tortoises (if you must know what that is) monitoring stations. Not all stations are monitored for a given survey and sometimes when we monitor we don't find any and thus record a 0 which is a valid result.
In the crosstab when the station isn't used I would like it to say "N/A" or some other equivalent, but when it's a zero I want it to stay as zero.
I've found so much on how to change a null to a zero, but nothing when you want to keep the zero and somehow note the null.
Below is what the crosstab should look like. You'll see that the 0 in Station4 on 1/1/2004 is "real" (meaning we didn't find any) but all of the N/A's are when we didn't use the station.
Survey Dates
| | 1/1/2000 | 1/1/2002 | 1/1/2004 | 1/1/2006 |
|----------|----------|----------|----------|----------|
| Station1 | 9 | 5 | N/A | N/A |
| Station2 | 5 | 7 | 2 | 6 |
| Station3 | N/A | N/A | 6 | 9 |
| Station4 | 10 | 9 | 0 | 11 |
This is what the Oracle table look like for the 1/1/2000 survey as an example
| SurveyID | StationID | Number |
|----------|-----------|--------|
| 1 | 1 | 9 |
| 1 | 2 | 5 |
| 1 | 4 | 6 |
So, basically how to I keep the zero's and put some text in the nulls in a CR crosstab?
Thanks!
Because CR doesn't differentiate between nulls and actual zeros in the crosstab, you can try replacing actual zero values with a placeholder so you can tell the difference. Note that this solution will only work if you are trying to display the values and not do any aggregate calculations.
First, create a formula that will replace the zeros with a placeholder value. In this case, I'm using -1 since that number should never appear in the database.
//{#Survey Num}
local numbervar totalSurvey;
totalSurvey:={Table.ActiveBurrows} + {Table.InactiveBurrows};
if totalSurvey=0 then -1 else totalSurvey
Use this formula to create your crosstab. Now you need to set a display string so that everything appears correctly. Right-click one of your crosstab cells → hit "Format Field" → select the "Common" tab → then create a "Display String" formula. That formula should be something like:
if currentfieldvalue=-1 then "0" else if currentfieldvalue=0 then "N/A" else totext(currentfieldvalue,0,'')
Now you're basically just printing the real values over top of the placeholders.
