I am selecting a table that has multiple of the same records (same REQUEST_ID) with different VERSION_NO. So I want to sort it descending so I can take the highest number (latest record).
This is what I have...
IF it_temp2[] IS NOT INITIAL.
SELECT request_id
version_no
status
item_list_id
mod_timestamp
FROM ptreq_header INTO TABLE it_abs3
FOR ALL ENTRIES IN it_temp2
WHERE item_list_id EQ it_temp2-itemid.
ENDIF.
So version_no is one of the SELECT field but I want to sort that field (descending) and only take the first row.
I was doing some research and read that SORT * BY * won't work with FOR ALL ENTRIES. But that's just my understanding from reading up.
Please let me know how I can make this work. Thanks
You can simply sort the itab after the select and delete all adjecent duplicates afterwards, if wanted:
SORT it_abs3 BY request_id [ASCENDING] version_no DESCENDING.
DELETE ADJACENT DUPLICATES FROM it_abs3 COMPARE request_id.
Depending on the amount of expected garbage (to be deleted lines) in the itab an SQL approach is better. See Used_By_Already's answer.
If you are using the term "latest" to indicate "the most recent entry", then the field mod_timestamp appears to be relevant and you could use it this way to choose only the most recent records for each request_id.
SELECT
request_id
, version_no
, status
, item_list_id
, mod_timestamp
FROM ptreq_header h
INNER JOIN (
SELECT
request_id
, MAX(mod_timestamp) AS latest
FROM ptreq_header
GROUP BY
request_id
) l
ON h.request_id = l.request_id
AND h.mod_timestamp = l.latest
If you want the largest version_no, then instead of MAX(mod_timestamp) use MAX(version_no)
Just declare the it_abs3 as a sorted table with key that would consist of the columns you want to sort by.
You can also sort the table after the query.
SORT it_abs3 BY ...

I have table[Table 1] having three columns
OrganizationName, FieldName, Acres having data as follows
organizationname fieldname Acres
ABC |F1 |0.96
ABC |F1 |0.96
ABC |F1 |0.64
I want to calculate the sum of Distinct values of Acres
(eg: 0.96+0.64) in DAX.
One of the problems with doing what you want is that many measures rely on filters and not actual table expressions. So, getting a distinct list of values and then filtering the table by those values, just gives you the whole table back.
The iterator functions are handy and operate on table expressions, so try SUMX
TotalDistinctAcreage = SUMX(DISTINCT(Table1[Acres]),[Acres])
This will generate a table that is one column containing only the distinct values for Acres, and then add them up. Note that this is only looking at the Acres column, so if different fields and organizations had the same acreage -- then that acreage would still only be counted once in this sum.
If instead you want to add up the acreage simply on distinct rows, then just make a small change:
TotalAcreageOnDistinctRows = SUMX(DISTINCT(Table1),[Acres])
Hope it helps.
Ok, you added these requirements:
Thank You. :) However, I want to add Distinct values of Acres for a
Particular Fieldname. Is this possible? – Pooja 3 hours ago
The easiest way really is just to go ahead and slice or filter the original measure that I gave you. But if you have to apply the filter context in DAX, you can do it like this:
Measure =
SUMX(
FILTER(
SUMMARIZE( Table1, [FieldName], [Value] )
, [FieldName] = "<put the name of your specific field here"
)
, [Value]
)
These are the field (crane_no) values to be sorted
QC11QC10QC9
I tried the following query:
select * from table order by crane_no DESC
but query results does not give in an order because the field is mixed with staring and number (Example:QC12).
I get following results for above query:
QC9QC11QC10
I want the results to be in order (QC9, QC10, QC11). Thanks
If the data isn't huge, I'd use a regex order by clause:
select
cran_no
from your_table
order by
regexp_substr(cran_no, '^\D*') nulls first,
to_number(regexp_substr(cran_no, '\d+'))
This looks for the numbers in the string, so rows like 'QCC20', 'DCDS90' are ordered properly; it also takes care of nulls.
One approach is to extract the numeric portion of the crane_no columns using SUBSTR(), cast to an integer, and order descending by this value.
SELECT *
FROM yourTable
ORDER BY CAST(SUBSTR(crane_no, 3) AS INT) DESC
Note that I assume in my answer that every entry in crane_no is prefixed with the fixed width QC. If not, then we would have to do more work to identify the numerical component.
select ...
order by to_number( substr( crane_no,3 )) desc
I have a scenario to be implemented in informatica where I need to remove duplicate records from a table based on PK. But I need to keep the 1st occurrence of the PK values and remove the others(in case of duplicate PK).
For example, If my source has 1,1,1,2,3,3,4,5,4. I want to see my target data as 1,2,3,4,5. I have to read data from the same table and need to load into the same table., no new table can be introduced. please help me with your inputs.
Thanks in Advance!
I suppose you want the first occurrence because there are other (data) columns in addition to the key you entered. Therefore you want
1,b
1,c
1,a
2,d
3,c
3,d
4,e
5,f
4,b
Turned into
1,b
2,d
3,c
4,e
5,f
??
In that case try this mapping layout:
SRC -> SQ -> SRT -> AGG -> TGT
SEQ /
Where the sorter is set to sort on the KEY,sequence_port (desc)
And the aggregator is set to group by the KEY, and the sequence_port should not go out of the sorter
Hope you can follow me :)
There are multiple ways to do this, the simplest would be too do it in the SQL override.
Assuming the example quoted above, the SQL would be like this. General idea is to set a row number for a primary key ( so if you have 3 rows with same pk they will have 1,2,3 as row numbers before being reset for the next pk)
SQL:
select * from (
Select primary_key,column2 row_number() over (partition by primary_key order by primary_key) as distinct_key) where distinct_key=1
Before:
1,b
1,c
1,a
2,d
3,c
3,d
Intermediate query:
1,c,1
1,a,2
2,d,1
3,c,1
3,d,2
output:
1,c
2,d
3,d
I am able to achieve this by following the below steps.
1. Passing Sorted data(keys are EMP_ID, MOBILE, DEPTID) to an expression.
2. Creating the following variable ports in the expression and getting the counts.
V_CURR_EMP_ID = EMP_ID
V_CURR_MOBILE = MOBILE
V_CURR_DEPTID = DEPTID
V_COUNT =
IIF(V_CURR_EMP_ID=V_PREV_EMP_ID AND V_CURR_MOBILE=V_PREV_MOBILE AND V_CURR_DEPTID=V_PREV_DEPTID ,V_COUNT+1,1)
V_PREV_EMP_ID = EMP_ID
V_PREV_MOBILE = MOBILE
V_PREV_DEPTID = DEPTID
O_COUNT =V_COUNT
3. In the next transformation which is filter, I am taking only the records which have count more than 1 and deleting them using update strategy(DD_DELETE).
Here is the mapping flow.
SQ->SRTR->EXP->FIL->UPD->TGT
Also, when I tried to delete them using aggregator , it is deleting only the first occurrence of duplicates but not all.
Thanks again for your inputs!
For a SSRS report, I'm trying to return a list of sorted data from a dimension to use with a parameter.
My dimension is [Radio].[Radio NO].[Radio NO] where the last Radio NO is a string.
I can find examples of returning one column while sorting on another but I can't figure out how to sort and return just one column.
Thanks whytheq! Based on your answer, here's what I came up with that works:
SELECT {} ON COLUMNS,
ORDER(
[Radio].[Radio NO].[Radio NO].MEMBERS
,[Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
,BASC
) On ROWS
FROM [OurCube]
Without seeing the exact structure of your cube / query an avenue you could explore, if you'd like to order alphabetical, is the following
ORDER(
[Radio].[Radio NO].[Radio NO].MEMBERS
,[Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
,BDESC
)
If you want to order by a measure in your cube, then something like the following:
ORDER(
[Radio].[Radio NO].[Radio NO].MEMBERS
,[Measures].[Profit]
,BDESC
)
This is a possible if you really need to change the column name before hitting SSRS but it has the disadvantage of changing it to a measure:
WITH
MEMBER [Measures].[thisIsTheNewName] AS
[Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
SELECT
{[Measures].[thisIsTheNewName]} ON COLUMNS,
ORDER(
[Radio].[Radio NO].[Radio NO].MEMBERS
,[Radio].[Radio NO].CURRENTMEMBER.MEMBER_CAPTION
,BASC
) On ROWS
FROM [OurCube];
Over in the SQL side, my data is looking like this:
Select f.id, f.TimeKey,t.CalendarYearMonth
from FactSubmission f
inner join DimTime t on t.TimeKey = f.TimeKey
order by f.Id asc
Sorting from MDX we have descending
SELECT
NON EMPTY ORDER(
[DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
[DimTime.CalendarYearMonth].CurrentMember.Properties("MEMBER_KEY"),
DESC
) ON COLUMNS
FROM [PSE_FactSubmission]
And Ascending
The January dates aren't at the top of either sort, which suggests I'm sorting by the FactSubmission.ID key instead of DimTime.CalendarYearMonth
Is this how things are supposed to work? I'd like to pull back Jan,Feb,March.
DimTime.CalendarYearMonthNum is a column with data in the form 201501,201502,201503 etc. Here's an attempt at using this column to to sort the CalendarYearMonth data.
Debugging Query to Select Keys
NonEmpty Query
Try ordering using a different property:
SELECT
NON EMPTY ORDER(
[DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
[DimTime.CalendarYearMonth].CurrentMember.Properties("MEMBER_Value"),
DESC
) ON COLUMNS
FROM [PSE_FactSubmission];
or maybe this:
SELECT
NON EMPTY ORDER(
[DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
[DimTime.CalendarYearMonth].CurrentMember.MEMBERValue,
DESC
) ON COLUMNS
FROM [PSE_FactSubmission];
In the above you should be good using DESC - sometimes you need to break the underlying hierarchical ordering by adding a B i.e. BDESC
From here I cannot see MEMBER_VALUE: http://mondrian.pentaho.com/documentation/mdx.php
...but there is a function .VALUE so maybe try the following:
SELECT
NON EMPTY ORDER(
[DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
[DimTime.CalendarYearMonth].CurrentMember.Value,
DESC
) ON COLUMNS
FROM [PSE_FactSubmission];
Strange that the key doesn't work. What values do you get if you run something like this?
WITH MEMBER [KEYcheck] AS
[DimTime.CalendarYearMonth].CurrentMember.Properties("MEMBER_KEY")
//[DimTime.CalendarYearMonth].CurrentMember.MEMBER_KEY
//[DimTime.CalendarYearMonth].[CalendarYearMonth].CurrentMember.MEMBER_KEY
//[DimTime].CurrentMember.MEMBER_KEY
SELECT
[KEYcheck] ON 0,
[DimTime.CalendarYearMonth].[CalendarYearMonth].Members ON 1
FROM [PSE_FactSubmission];
You are doing an alphabetical sort. February->January->March.
For doing a sort based on the month number, there needs to be a field which maps January-1, February-2, March-3.
If you have such a column in cube, use that to to sort. If not create a calculated member like below -
WITH MEMBER Measures.CalendarMonth AS
CASE [DimTime.CalendarYearMonth].CurrentMember
WHEN [DimTime.CalendarYearMonth].&[January] THEN 1
WHEN [DimTime.CalendarYearMonth].&[February] THEN 2
WHEN [DimTime.CalendarYearMonth].&[March] THEN 3
END
SELECT
NON EMPTY ORDER(
[DimTime.CalendarYearMonth].[CalendarYearMonth].Members,
Measures.CalendarMonth,
DESC
) ON COLUMNS
FROM [PSE_FactSubmission]
EDIT for Andrew
with member Measures.[MonthNum] as
NonEmpty
(
[DimTime.CalendarYearMonthNum].[CalendarMonthNum].members,
([DimTime.CalendarYearMonth].[CalendarYearMonth].currentmember, Measures.foo)
).item(0).membervalue
select
non empty
order
(
[DimTime.CalendarYearMonth].[CalendarYearMonth].members,
Measures.[MonthNum],
desc
) on rows
from [PSE_FactSubmission]
EDIT - with EXISTS
with member Measures.[MonthNum] as
EXISTS
(
[DimTime.CalendarYearMonthNum].[CalendarMonthNum].members,
[DimTime.CalendarYearMonth].[CalendarYearMonth].currentmember,
"SomeMeasureGroup"
).item(0).membervalue
