ThanksHi,
I suggest you to use the function below:
CREATE OR REPLACE FUNCTION isanyrow(v_table_name varchar2, v_clause_where varchar2)
return varchar2
is
l_sql          varchar2(1000):=' ';
v_test          pls_integer;
l_clause_where     varchar2(1000);
v_msg varchar2(5);
BEGIN
l_clause_where:=v_clause_where;
if length(l_clause_where)=0 or l_clause_where is null then
     l_clause_where:='1=1';
end if;
l_sql:='select count(*) from '|| v_table_name || ' where ' || v_clause_where;
execute immediate l_sql into v_test;
dbms_output.put_line( 'Rows: ' ||v_test|| ' sql: '||l_sql);
if (v_test is null) or (v_test=0) then
v_msg :='FALSE';
elsif v_test > 0 then
v_msg :='TRUE';
end if;
return v_msg;
END;
where you can pass your coursor sql query as parameter(s).

Ion

How to get information about cursor? I had only a reference on it.

Hello
How to get information about cursor, that I receive in my procedure as a reference. For example I need to know, a number of columns. I know nothing about this cursor, except the link on it.
Best Regards, Kostya Proskudin!

However, I would seriously reconsider what you are trying to achieve.
It looks like you are trying to write some ultimately generic cursor processor. i.e. pass any cursor and process it in some generic way.
Good design should include knowledge of what is expected to be passed and that knowledge can be put into the code.
Generic code is inherently difficult to maintain and debug and will never 100% deal with all possible situations e.g. even if you know the table being queried in the cursor you can't rely on the data dictionary to give you all the returned columns if some of the returned columns of the cursor are computed columns.
Be careful you aren't writing something that's going to cause problems later.

How to get count of rows for a table?

Hi,
How to get count of rows for a table and secondly, how can i have access to a particular cell in a table?
Regards,
Devashish

Hi Devashish,
WdContext.node<Your_node_name>().size() will give you the no: of rows.
This should be the node that is bound to the table's datasource property.
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value); will select the row at that particular index.
You can access an attribute of a particular row as
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value).get<attribute_name>();
Hope this helps,
Best Regards,
Nibu.

How to get COUNT of Invoice No and Sales Order No from Multiprovider

Hello Guys,
I have a scenario like below. I have 2 info cubes (1) Billing Item Info cube (2) Sales Order Item Infocube which stores Item level data in infocube. I created Multiprovider for these Sales Order Item Cube and Billing Item Info cube.
Now in My Multiprovider, Invoice No and Sales Order No gets repeated no of times because one Invoice and One order will have no of Materials. I have a requirement to count Total No of Billing Document and Total No of Sales Document for a Day in the BEx Report. I was thinking to use COUNT function but if Sales Document or Billing Document gets repeated then it will count those records which i don't want. correct me if i am wrong.
How to get Total no of Billing Document and Total no of Sales Document from a Multiprovider where i have Item level data is stored ?

Hi,
Count can be achieved as per the following document. Create for Billing Doc and Sales Doc separately.

How to get count of a resultSet?

Hi, everyone,
Could anybody please tell me how to get the count of how many records in a resultSet? I went through the Java API for ResultSet, there is no such method in it.
Thanks.

Hi,
I personnally simply use an INT variable which I increment during the loop, something like this :
int nbRows = 0;
while (rs.next()) {
// do your rs.getXXX stuff here
nbRows++;
System.out.println("Total Nr of rows : "+nbRows);
nbRows++. But there might be another better method for this ?
You could also use an SQL Request like select count(*) or something, but this would be too much expensive for the performance (an additional statement, Result Set, SQL Query etc...).
Hope this helps

How to get count for missing month

I created a view as follows:
CREATE OR REPLACE FORCE VIEW "Vinfection1" ("MONTH", "COUNT") AS
select "MONTH","COUNT" from (
select to_char(s.pdate,'Mon-yyyy') as month, count(*) as count
from surproc s, diagnosis_surproc d
where s.surprocid = d.surprocid and d.diagnosisid in ('506', '507', '508', '509', '510')
group by to_char(pdate,'Mon-yyyy'))
order by to_date(month,'Mon-yyyy')
Some months are missing in the view. I want to put that month and 0 in the view. How to do it?
Thanks,
Jennifer

Hi, Jennifer,
You need to outer-join to some table or result set (such as all_months, below) that has one roe per month.
Here's one way:
CREATE OR REPLACE FORCE VIEW Vinfection1 (month, month_s, cnt) AS
WITH    all_months     AS
     SELECT ADD_MONTHS (first_month, LEVEL - 1)     AS month
     FROM     (
              SELECT TRUNC (MIN (pdate), 'MONTH')     AS first_month
              ,         TRUNC (MAX (pdate), 'MONTH')     AS last_month
              FROM    surproc
     CONNECT BY     LEVEL <= 1 + MONTHS_NETWEEN (last_month, first_month)
SELECT a.month
,     TO_CHAR (a.month, 'Mon-yyyy')     AS month_s
,     COUNT (*)                 AS cnt
FROM              all_months      a
LEFT OUTER JOIN      (     surproc               s
               JOIN   diagnosis_surproc      d ON   s.surprocid     = d.surprocid
                                      AND d.diagnosisid     IN ('506', '507', '508', '509', '510')
           )     ON a.month     = TRUNC (s.pdate)
GROUP BY a.month
/Avoid table- and column names that are non-standatrd (such as names that need double-quotes), or are built-in function names (such as COUNT).
Don't use ORDER BY in a view. Almost anything you do with the view will cause the ordering to be lost anyway.
Even if you do have an ORDER BY clause in the view, you'll often want to ORDER BY month. Rather than call TO_DATE whenever you need to sort, I suggest having two month columns; month (whcih is a DATE) for sorting, filtering and joining, and month_s (whcih is a VARCHAR2) for displaying.
Use ANSI join syntax, especiallly for outer joins.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

How to get the current cursor position in word report?

I am generating a word report. But I would like to keep the table in one page. However, I did not find the way to do it in labview. Somebody would give me some suggestions? I appreciate a lot.
One way I think I can do is to find the current cursor position. Since I know the table size so I can figure out if the left space in the current page is enough to hold the table. But I do not know how to locate the curent cursor position in word document in labview programmatically. I appreciate any suggestions on this question.
Thanks.

Hi,
when you insert data in a word document you have to refer to bookmarks rather than cursor position.
If you are using the Report Generation Toolkit for Office it is explained in the manual chapter 3-1.
See also the example: Generate Report From Template (Word).vi included in the toolkit.
If you aren't using the toolkit, you still have to refer to bookmark as reference points to insert and/or fetch data.
The principle is:
- First create a document in which you insert bookmarks where you wish and save it as a template
- In LV open your template document and insert in it your data referring to bookmarks as insertion points
- At the end save your report with another name, so you still have the template
I hope I have been clear enough, if not just as
k!
Good luck,
Alberto

How to get count of group of current login user if AD Group is added in SharePoint Group?

My Client has 2 SharePoint Application. For the AD Users they have created AD Group and added users in that AD Group as per requirement. Later AD Group is added in SharePoint Group. When I'm trying to fetch Current User Group count, I can able to get the
count of Groups using below statement.
int groupCount = SPContext.Current.Web.CurrentUser.Groups.Count;
Above Statement, returns always 0 value if I tried with User who are added in AD Group and if I add AD User and then it will return the exact count.
Please suggest solution to get Count of Group of Current User. My Application contains more than 60 SharePoint group.

Hello,
I believe your code doesn't count those AD group users until they login at least once. If this is the case then try to use "SPUtility.GetPrincipalsInGroup" as suggested in below post:

How to get count of all records of all entities in CRM Online

Hi,
I want to get count of all records entitywise in dynamics CRM 2013 online. I know we can count the records in CRM on-premise using a SQL query in report. Earlier I wrote a SSRS report to count the records in a CRM entity wise as displayed in
the screenshot below..
Can someone suggest me a good approach to implement the same in CRM Online.
Thanks
Pratibha Singh

Hello,
In a CRM Online environment, you need to create reports based on Fetch XML. Take a look at this link to create a Fetch XML query with aggregates: https://msdn.microsoft.com/en-us/library/gg309565.aspx?f=255&MSPPError=-2147217396#count .
Here is an example to create a report in an online environment: http://edwardsdna.com/2012/12/03/crmonline-report/
Hope it helps,
Kind regards

How to get count as 0 for records not in table

Hi All,
I have requirement where I need count of records in the table based on ids. Example query below
SELECT empid ,
nvl(COUNT(id), 0) empcount
FROM employee
WHERE empid IN(1, 2, 4, 5)
GROUP BY empid
In the table only record for "empid=2" is present so I get count 1 for it. But with it I should get count as 0 for non existing records. Expecting below output
empid | empcount
1 | 0
2 | 1
4 | 0
5 | 0
Appreciate your help and Thanks in advance.
Regards.
Ashish

e.g.
SQL> select column_value deptno, count (deptno)
from emp, table (sys.odcinumberlist (10, 20, 100))
where deptno(+) = column_value
group by column_value
    DEPTNO COUNT(DEPTNO)
        10             3
        20             5
       100             0

How to get counter value from Historian

Hi Experts,
We have got a scenario to keep the number (counter) to see how many time a value of tag have been changed.
For Example:
If the values change from 1 to 0 and 0 to 1 for 25 times in a minute. We would like to get this number (25) from Historian (Wonderware).
Currently we are not using any Pco to fetch the value from Hisotrian since we are able to fetch the tag values from Historian database through SQLConnection.
I would like to know if we introduce Pco, will that help us to get this counter value.
We are working on MII 15.0 version.
Any help of this very much appreciated.
Thanks
Shaji

Hi Shaji,
PCo OPC DA does not support PCoQuery TagAggregateMode as it only has access to Current Values of OPC Tags, because OPC DA only provides Current Value access.
I know it is possible to execute SQL queries against the Wonderware Historian to retrieve counts aggregates, but don't have the details handy. Recommend that you deploy the InSQLPCo Data Server in MII and try using the PCoQuery TagAggregateMode method to retrieve the Counts aggregate first.

HOW TO GET COUNT IN OF COMPOSITE PRIMARY KEYS USING ECLIPSELINK

Hi all,
We are currently migrating our application form oracle 10g to 11 g and hence migrating from toplink to eclipselink.
we are unable to fire the count query and getting the following exception ...
Error Code: 909
Call: SELECT COUNT() FROM T_USER_MESSAGE t0, T_USER t2, T_MESSAGE_RECIPIENT t1 WHERE ((((t2.PERSISTENT_ID = ?) AND (t2.SITE_CODE = ?)) AND (t1.DELETED_BY_RECIPIENT = ?)) AND (((t2.PERSISTENT_ID = t1.RECIPIENT_ID) AND (t2.SITE_CODE = t1.RECIPIENT_SITE)) AND ((t0.PERSISTENT_ID = t1.MESSAGE_ID) AND (t0.SITE_CODE = t1.MESSAGE_SITE))))
bind => [13398610, 1, F]
please advise .
we suspect that this could be because of the composite primary key in one of the tables .
any pointers to specify how count(*) could be used in this scenario would be of great help ..
Thanks in advance

What is the query being used, include the JPQL/expression code.
What is the error message (I assume this is a database error?).
What version are you using, can you try the latest EclipseLink 2.1 release.

How to get count(*) in ABAP Query...

Hi All,
Can someone of you tell me, how to do the following in the ABAP Query. I want to get the count of records retreived during the query execution and display it in the output.
example::: Select count(*) from VBRK.
Thanks a lot.
Thanks!
Puneet.

From help doc:
Note
The SELECT COUNT( * ) FROM ... statement returns a result table containing a single line with the result 0 if there are no records in the database table that meet the selection criteria. In an exception to the above rule, SY-SUBRC is set to 4 in this case, and SY-DBCNT to zero.
You can just run SELECT COUNT (*) FROM TABLE
Number of rows is returned in SY-DBCNT
