Rows count for repetitive groups in tablix.

Hi All,
To make the story cut short, i will going to explain my scenario:
i have a tablis contro and i garoup it by a field say "Field1" which contains A and B values,
in my case we divide groups in two parts if it has rows more then 200.
so, my report output and my required is below :
Current Output -------------------------- Required layout
here 200, 20, 30 are number of rows per group.
now my requirement is if a group is repetitive
i need the all rows count for that value like in above case :
Header text of Group A should be like : A(220) i.e 200 +20
please help me on this...
it is very urgent for me
shashank

hi Simon,
thanks for reply, sorry, i skipped to mentioned that i have to provide multilevel grouping also, like
Group By: Field 1 -> Field 2 -> field3
so, to achieve my requirement by Sql as solution has no problem if i do not have multilevel grouping, but i have to provide that and in that case the query will be like,
“select distinct [column1],[Column2],[Column3],count(*) as rn from [table] group by [column1],[Column2],[Column3]”
which is problematic in my case.
so for doing this i need a solution apart from sql but by using SSRS Report end.
Thanks again.

Count() for each group, but only groups having 1+ element like... AND all elements like...

There are tables(and columns) like:
'Clients'(clientID)
'Houses' (houseID)
'Visits' (clientID, houseID, visit_date)
'Contracts'(contractID, houseID, clientID, rentDate_from, rentDate_end)
I have problem with writing MS SQL query of this kind:
how many visits to houses did each client, before renting one of them?
Its easy to count total number of Visits for each client, listing all visits + group by clientID and selecting count(*) for each group.
Lets say this is select_1, and select_2 is listing all Contracts for all clients.
Select_1 is not answer, because count must be performed only on groups, which:
-have at least 1 row "like" row in select_2 (it means that at least one of visited houses was rented, because it can happen that client visited few houses, but rented other, not visited house). my idea for this is comparing select_1 and select_2 with:
"where s1.clientID=s2.clientID and s1.houseID=s2.houseID"
-each group must have all rows(visits) with date of same day or earlier than contract date
maybe: "datediff(day, s1.visit_date, s2.rentDate_from) >= 0"

In future, please provide proper DML, DDL and example data, like I have for you below.
DECLARE @clients TABLE (clientID INT, name VARCHAR(20))
INSERT INTO @clients (clientID, name)
VALUES (1, 'Jonathan'),(2, 'Christopher'),(3, 'James'),(4, 'Jean-Luc'),(5, 'William')
DECLARE @houses TABLE (houseID INT, address VARCHAR(20))
INSERT INTO @houses (houseID, address)
VALUES (1, 'NX01'),(2, 'NCC 1701'),(3, 'NCC 1071A'),(4, 'NCC 1701D'),(5, 'NCC 1701E')
DECLARE @visits TABLE (clientID INT, houseID INT, visitDateTime DATETIME)
INSERT INTO @visits (clientID, houseID, visitDateTime)
VALUES (1,1,'2001-01-01 12:13:14'),
(2,2,'2001-01-02 12:13:14'),

INSERT INTO @contracts (houseID, clientID, rentStartDate, rentEndDate)

How to get row count(*) for each table that matches a pattern

I have the following query that returns all tables that match a pattern (tablename_ and then 4 digits). I also want to return the row counts for these tables.
Currently a single column is returned: tablename. I want to add the column RowCount.
DECLARE @SQLCommand nvarchar(4000)
DECLARE @TableName varchar(128)
SET @TableName = 'ods_TTstat_master' --<<<<<< change this to a table name
SET @SQLCommand = 'SELECT [name] as zhistTables FROM dbo.sysobjects WHERE name like ''%' + @TableName + '%'' and objectproperty(id,N''IsUserTable'')=1 ORDER BY name DESC'
EXEC sp_executesql @SQLCommand

The like operator requires a string operand.

Example:
DECLARE @Like varchar(50) = '%frame%';
SELECT * FROM Production.Product WHERE Name like @Like;
-- (79 row(s) affected)

with acount as

select count(*) as countb from dual -- put your table name here
ccount as

Problem w/: Error while getting estimated row count for view

JDev 10.1.3 - Steps
1. created a ADF VO w/ one bind variable vNAME.
2. Created a basic jspx page, use the data control pal. to drop in VO w/ executeparam option. Use the data control pal to drop in VO w/ ADF Read-Only Table w/ select and sort option. Selected all VO columns in table.
3. Following Error msg occurs when running jspx page -
oracle.jbo.DMLException: Error while getting estimated row count for view object CategoryView, statement SELECT count(1) FROM (SELECT
CATEGORY.CATID CATID,
CATEGORY.NAME NAME,
CATEGORY.PICTURE PICTURE,
CATEGORY.ACTIVE ACTIVE
FROM
CATEGORY
WHERE
(CATEGORY.NAME LIKE UPPER(:vName)||'%')) .
Tested SQL Statement in SQL Worksheet works ok (with a Value replacing ':vName').
Can anyone advise - seems to be a straight forward process that is returning this error msg. I have tried variations of the SQL stmt with no luck. The jspx page errors when the ADF Read-Only Table is added.

I seem 2 have the same error, in a slightly different situation.
I have a view which subclasses a Entity with a history column 'CreatedOn'. When performing a quick search/filter on this column I get the same error. The ADF app is build on a DB2 database, so no named parameters here. Instead invalid SQL is created when executing the estimated row count. The WHERE clause contains 'CreatedOn = null', should be 'CreatedOn is null'. Furthermore the input of my quick search is not filled in this clause.
Any help would be appreciated

CR - giving total transaction count for few groups and 0 for few groups.

For the column "No of First Call Resolution" I have to count no of interactions based on the Interaction Result, the formula is
COUNT(Interaction_ID) WHERE INTERACTION_RESULT = 'FCR'
For which, I wrote the below formula
If {14CICustomerInteractions_query.Interaction Result} = "FCR" then Count ({14CICustomerInteractions_query.Interaction_ID})
I have 33,232 interactions on the particular day I selected. When I try to group up and do the calculations it is giving total transaction count for few groups and 0 for few groups.
Need Solution

Hi,
What field is the report grouped on?
If you wish to find the no of interactions based on some condition and display it for every group, then here's what you need to do:
1) Create this formula and place this on the details section:
whileprintingrecords;
numbervar c;
If {14CICustomerInteractions_query.Interaction Result} = "FCR" then
c := c + 1;
2) Create another formula and place this one on the Group Footer:
whileprintingrecords;
numbervar c;
3) Create this formula to reset the variable and place this on the Group Header:
whileprintingrecords;
numbervar c := 0;
Let me know how this goes!

Trying to get row counts for all tables at a time

Hi,
i am trying to get row counts in database at a time with below query but i am getting error:
its giving me ora-19202 error..please advise me
select
      table_name,
      to_number(
        extractvalue(
          xmltype(dbms_xmlgen.getxml('select count(*) c from '||table_name))
          ,'/ROWSET/ROW/C')
          count
    from all_tables;

ALL_TABLES returns tables/views current user has access to. These tables/views are owned not just by current user. However your code
dbms_xmlgen.getxml('select count(*) c from '||table_name)does not specify who the owner is. You need to change it to:
dbms_xmlgen.getxml('select count(*) c from '||owner || '.' || table_name)However, it still will not work. Why? As I said, ALL_TABLES returns tables/views current user has access to. Any type of access, not just SELECT. So if current user is, for example, granted nothing but UPDATE on some table the above select will fail. You would have to filter ALL_TABLES through ALL_SYS_PRIVS, ALL_ROLE_PRIVS, ALL_TAB_PRIVS and PUBLIC to get list of tables current user can select from. For example, code below does it for tables/views owned by current user and tables/views current user is explicitly granted SELECT:
select
      t.owner,
      t.table_name,
      to_number(
        extractvalue(
          xmltype(dbms_xmlgen.getxml('select count(*) c from '||t.owner || '.' || t.table_name))
          ,'/ROWSET/ROW/C')
          count
    from all_tables t,user_tab_privs p
    where t.owner = p.owner
      and t.table_name = p.table_name
      and privilege = 'SELECT'

Different row count for select versus insert in XML query

Hi,
I encounter a situation where a SELECT * returns a different rows count than an INSERT INTO... (SELECT *) by xmltable join. This makes no sense at all!!!
In breif, I tried to convert xml data into traditional relational tables. I wrote an xml query to select data from xmltable... I checked row count. When I used "create table as select" that was the same query above, I got correct row count. However when I used "insert into select" that was the same query above, I got the wrong info in the table I just inserted.
Does any one have any idea what caused this issue? Thanks for your help.

Getting the max count for each group

Hi, I am a newbie and working on a project for school. I have been working this problem for a couple of days and made a bit of progress.
I have two tables, student and enroll for a college database. I need to show the students who have the most enrollments in each major. So far, I have:
WITH COUNT_Q AS
SELECT B.SSN, B.MAJOR, COUNT (A.CLASS_NO) AS COUNTCLASS
FROM ENROLL A, STUDENT B
WHERE A.SSN = B.SSN
GROUP BY B.SSN, B.MAJOR
SELECT MAX(COUNTCLASS), MAJOR
FROM COUNT_Q
GROUP BY MAJOR
I am getting the correct results but need to show the SSN and Major of the studens. When I add in the SSN and Major, like below, I get back too many records.
WITH COUNT_Q AS
SELECT B.NAME, B.SSN, B.MAJOR, COUNT(A.SSN) AS COUNTCLASS
FROM ENROLL A, STUDENT B
WHERE A.SSN = B.SSN
GROUP BY B.NAME, B.SSN, B.MAJOR
SELECT *
FROM COUNT_Q
WHERE (COUNTCLASS) IN (SELECT MAX(COUNTCLASS)
FROM COUNT_Q
GROUP BY MAJOR
Can someone help point me in the right direction?

SELECT B.NAME,
        B.SSN,
        B.MAJOR
FROM (
         SELECT B.NAME,
                 B.SSN,
                 B.MAJOR,
                 COUNT(A.CLASS_NO) SSN_MAJOR_COUNTCLASS
                 DENSE_RANK() OVER(PARTITION BY MAJOR ORDER BY COUNT(A.CLASS_NO) DESC) RNK
           FROM ENROLL A,
                 STUDENT B
           WHERE A.SSN = B.SSN
           GROUP BY B.NAME,
                    B.SSN,

How can we split limit row counts for DB2?

We want to mass data from DB2. but, we guess 200,000,000 count.
so we try to split by 5,000 count and almost 5 MB.
How can we use sql query for DB2? How can we make JDBC Sender?
but, We don't use update query. because Customer did not allow ours requirement.
How can we do?

Well, there are ways, how to achieve success, but in all of them must customer do some changes in their database.
a, create "interface table", run select into (load relevant data to it) and then run JDBC adapter select on this table using update statement to mark the processed lines
b, there is for sure a table, which is "main" - every record is replicated and every one is repliacted only once.. Add new column to this table and use it as a "marker" for already processed records..
...for example...
There may be of course more possibilites...
If you don't want to process all records at once, there must be some flag to distinguish already processed records from not processed ones..

table2 - 230 etc...
here is my query that works but display of the output is the way i wanted. can someone help me getting the output as above described.
