Hi I´m working in a projcet in SSRS and can't get this right. Maybe you can help me? So I have a report that looks like this with three different tablix where the middle one calculate the ratio of the other two. My problem is that i can't figure out how to calculate the Diff-column for the ratio rows.
I solved the ratio rows it like this:
=(Sum(iif(Fields!OutputType.Value = "123",
Fields!Production.Value, CDec(0))))/(Sum(iif(Fields!OutputType.Value = "456", Fields!Production.Value, CDec(0))))
The Diff column for the groups 123 and 456 I solved like this:
=(Sum(iif(Fields!MonthNo.Value = 2018, Fields!Production.Value, CDec(0))))-(Sum(iif(Fields!MonthNo.Value = Budget, Fields!Production.Value, CDec(0))))
I thought that a combination of the two expressions would solve my problem but I can't really get it right. I've tried something like this, but I just get zeros.
=(Sum(iif(Fields!MonthNo.Value = "2018",
(Sum(iif(Fields!OutputType.Value = "123", Fields!Production.Value, CDec(0))))/(Sum(iif(Fields!OutputType.Value = "456", Fields!Production.Value, CDec(0)))), CDec(0))))
-
(Sum(iif(Fields!MonthNo.Value = "Budget",
(Sum(iif(Fields!OutputType.Value = "123", Fields!Production.Value, CDec(0))))/(Sum(iif(Fields!OutputType.Value = "456", Fields!Production.Value, CDec(0)))), CDec(0))))

I'm trying to convince PostgreSQL 13 to pull out parts of a JSON field into another field, including a subset of properties within an array based on a discriminator (type) property. For example, given a data field containing:
{
"id": 1,
"type": "a",
"items": [
{ "size": "small", "color": "green" },
{ "size": "large", "color": "white" }
]
}
I'm trying to generate new_data like this:
{
"items": [
{ "size": "small" },
{ "size": "large"}
]
}
items can contain any number of entries. I've tried variations of SQL something like:
UPDATE my_table
SET new_data = (
CASE data->>'type'
WHEN 'a' THEN
json_build_object(
'items', json_agg(json_array_elements(data->'items') - 'color')
)
ELSE
null
END
);
but I can't seem to get it working. In this case, I get:
ERROR: set-returning functions are not allowed in UPDATE
LINE 6: 'items', json_agg(json_array_elements(data->'items')...
I can get a set of items using json_array_elements(data->'items') and thought I could roll this up into a JSON array using json_agg and remove unwanted keys using the - operator. But now I'm not sure if what I'm trying to do is possible. I'm guessing it's a case of PEBCAK. I've got about a dozen different types each with slightly different rules for how new_data should look, which is why I'm trying to fit the value for new_data into a type-based CASE statement.
Any tips, hints, or suggestions would be greatly appreciated.
One way is to handle the set json_array_elements() returns in a subquery.
UPDATE my_table
SET new_data = CASE
WHEN data->>'type' = 'a' THEN
(SELECT json_build_object('items',
json_agg(jae.item::jsonb - 'color'))
FROM json_array_elements(data->'items') jae(item))
END;

Also note that - isn't defined for json only for jsonb. So unless your columns are actually jsonb you need a cast. And you don't need an explicit ... ELSE NULL ... in a CASE expression, NULL is already the default value if no other value is specified in an ELSE branch.
I have a column of data called Date and I am using that to perform a switch. Basically the figure needs to be 120 on a weekday and 0 on a weekend so I have used.
=SWITCH
(Weekday(Fields!Date.Value) = "1", "0",
Weekday(Fields!Date.Value) = "2", "120",
Weekday(Fields!Date.Value) = "3", "120",
Weekday(Fields!Date.Value) = "4", "120",
Weekday(Fields!Date.Value) = "5", "120",
Weekday(Fields!Date.Value) = "6", "120",
Weekday(Fields!Date.Value) = "7", "0"
)
Which works great. However I also want a Total at the bottom of the sheet. I (somewhat naively) tried adding
=SUM( ... )
to the expression but that resulted in an #Error in the textbox. I also tried
=SUM(ReportItems!Textbox85.value)
and that didn't even run throwing the error
The Value expression for the textrun
'Textbox84.Paragraphs[0].TextRuns[0]' uses an aggregate function on a
report item. Aggregate functions can be used only on report items
contained in page headers and footers.
So my question is how do I sum up this switch function or do I need to rethink this? I guess functionally all I really need is count of the total weekdays so far "this" month (that stays accurate no matter what month is picked using the date parameters). I can then * that number by 120.
So I came at it from a different angle and tried a SQL based solution. I added a column with the code
,CASE
WHEN
DATEPART(dw,convert(date,format(dateadd(hh,1,[Start Time]),'dd/MM/yyyy'),103)) in (1,7)
THEN 0
ELSE 1
End as [weekday]
Then used
=Fields!weekday.Value*120
in my textbox and
=Sum(Fields!weekday.Value, "DataSet1")*120
in my total. Got the desired results.
I have a table that will return a number and i need to convert it into a text label
20 = Entered, 30 = Returned, 200 = Cancelled, 220 = Complete, 300 = Deleted
I want these to show in my report as simply 'Complete' etc.
Im able to use the replace function to get one value to show correctly in the report:
=Replace(Fields!status.Value,"220","Complete")
But i cant work out how to do this for each possible number that will show in this column
Best way would likely be modifying the query with a CASE statement as mentioned, if you are able to do that. But if not, a cleaner alternative to the nested Replaces would be to simply use a Switch statement:
=Switch(
Fields!Status.Value = "20", "Entered",
Fields!Status.Value = "30", "Returned",
Fields!Status.Value = "200", "Cancelled",
Fields!Status.Value = "220", "Complete",
Fields!Status.Value = "300", "Deleted"
)
This is not the most efficient way to do this, but it's a quick fix:
=Replace(Replace(Replace(Replace(Replace(Fields!status.Value,"220","Complete"), "200","Cancelled"),"300","Deleted"),"20","Entered"),"30","Returned")
A better way would be to modify your DataSet query to replace the numbers with a CASE statement. See this documentation:

I'm fairly new to couchbase and have tried to find the answer to a particular query I'm trying to create with not much success so far.
I've debated between using a view or N1QL for this particular case and settled with N1QL but haven't managed to get it to work so maybe a view is better after all.
Basically I have the document key (Group_1) for the following document:
Group_1
{
"cbType": "group",
"ID": 1,
"Name": "Group Atlas 3",
"StoreList": [
2,
4,
6
]
}
I also have 'store' documents, their keys are listed in this document's storelist. (Store_2, Store_4, Store_6 and they have a storeID value that is 2, 4 and 6) I basically want to obtain all 3 documents listed.
What I do have that works is I obtain this document with its id by doing:
var result = CouchbaseManager.Bucket.Get<dynamic>(couchbaseKey);
mygroup = JsonConvert.DeserializeObject<Group> (result.ToString());
I can then loop through it's storelist and obtain all it's stores in the same manner, but i don't need anything else from the group, all i want are the stores and would have prefered to do this in a single operation.
Does anyone know how to do a N1QL directly unto a specified document value?
Something like (and this is total imaginary non working code I'm just trying to clearly illustrate what I'm trying to get at):
SELECT * FROM mycouchbase WHERE documentkey IN
Group_1.StoreList
Thanks
UPDATE:
So Nic's solution does not work;
This is the closest I get to what I need atm:
SELECT b from DataBoard c USE KEYS ["Group_X"] UNNEST c.StoreList b;
"results":[{"b":2},{"b":4},{"b":6}]
Which returns the list of IDs of the Stores I want for any given group (Group_X) - I haven't found a way to get the full Stores instead of just the ID in the same statement yet.
Once I have, I'll post the full solution as well as all the speed bumps I've encountered in the process.
I apologize if I have a misunderstanding of your question, but I'm going to give it my best shot. If I misunderstood, please let me know and we'll work from there.
Let's use the following scenario:
group_1
{
"cbType": "group",
"ID": 1,
"Name": "Group Atlas 3",
"StoreList": [
2,
4,
6
]
}
store_2
{
"cbType": "store",
"ID": 2,
"name": "some store name"
}
store_4
{
"cbType": "store",
"ID": 4,
"name": "another store name"
}
store_6
{
"cbType": "store",
"ID": 6,
"name": "last store name"
}
Now lets say you wan't to query the stores from a particular group (group_1), but include no other information about the group. You essentially want to use N1QL's UNNEST and JOIN operators.
This might leave you with a query like so:
SELECT
stores.name
FROM `bucket-name-here` AS groups
UNNEST groups.StoreList AS groupstore
JOIN `bucket-name-here` AS stores ON KEYS ("store_" || groupstore.ID)
WHERE
META(groups).id = 'group_1';
A few assumptions are made in this. Both your documents exist in the same bucket and you only want to select from group_1. Of course you could use a LIKE and switch the group id to a percent wildcard.
Let me know if something doesn't make sense.
Best,
Try this query:
select Name
from buketname a join bucketname b ON KEYS a.StoreList
where Name="Group Atlas 3"
Based on your update, you can do the following:
SELECT b, s
FROM DataBoard c USE KEYS ["Group_X"]
UNNEST c.StoreList b
JOIN store_bucket s ON KEYS "Store_" || TO_STRING(b);
I have a similar requirement and I got what I needed with a query like this:
SELECT store
FROM `bucket-name-here` group
JOIN `bucket-name-here` store ON KEYS group.StoreList
WHERE group.cbType = 'group'
AND group.ID = 1
Writing a Reporting Service (2005) report
My DataSet returns something like this:
DESCRIPTION COUNT
Total Properties 12345
Demolished 1243
Non-Demolished 11102
:
:
I have this displayed as a table and this is fine.
Now I also want to display the data like this:
[ 12345 ] Total Properties
/ \
/ \
Non-Demolished [ 11102 ] [ 1243 ] Demolished
I can add the text-boxes and lines but what expression do I need to fill in the values?
Need somethig that returns the count based on a match to the description in the row.
Here is the way to do it.
First(Fields!FieldName.Value,"DataSetName")
Maybe you could do something like this:
=Iif(Fields!Description.Value = "Demolished", Fields!Count.Value, "Value not found")
