Can someone help me please?

You can use a column with data type number and not the database.
Setcalculation mode :summary summary function:count summarized block:your_block_name summarized item:name_column
Hope this helps...

How to count the number of data records?
Hey guys, how to count the number of records, I had on a data object variable?
Im having a result of sql query in a variable like this:
oDB.resolveNode("#command").query.select.value = "SELECT * FROM Customers WHERE CliNombre LIKE ' % ' + input1 +" %' ";
oDB.open ();
oDB.first ();
So I need to count the number of records retrieved by this SQL query at the moment. Help please
Then move the cursor back to the first record after you have your account.
There is a keyword count in SQL that will allow you to get the account of your request. You can run that first - get your account, and then run the actual query to get the Recordset. This would require a separate data connection. Some examples of code.
var xfa.event.newText = inName;
If (inName == "") {}
App.Alert ("you must enter a name--try again!")
}
var nIndex = 0;
While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection2")
{
nIndex ++;
}oDB = xfa.sourceSet.nodes.item (nIndex) .racing var (1); pertaining to the specified data connection node
App.Alert (ODB.saveXML ("Pretty"));var nIndex = 0;
While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection3")
{
nIndex ++;
}
var oDBCount = xfa.sourceSet.nodes.item (nIndex) .racing (1); pertaining to the specified data connection node
Configure sql call DB to get the number of records that match the criteriaoDBCount.nodes.item (1).query.setAttribute ("text", "commandType");
oDBCount.nodes.item (1).query.select.nodes.item (0) .value = "Select count (*) from table1 where AcctNumber = '" + inName + "'";
oDBCount.open)
oDBCount.close)Configure sql call DB to get the specified employee number
oDB.nodes.item (1).query.setAttribute ("text", "commandType");
oDB.nodes.item (1).query.select.nodes.item (0) .value = "Select * from table1 where AcctNumber = '" + inName + "'";
App.Alert (ODB. Nodes.Item (1) .saveXML ("Pretty"));now connect to the DB and get a recording
oDB.open)
oDB.close ();Note the SQL command use the keyword count (take a look at the oDBCount section). This will return a number of return to the cllaer. When I set up the data connection, a node count (*) that appeared there. I dragged to the form and it has created a field called count that the onus at this node. When the query is executed, the number of resulting records returns to this field. You can have hidden it so that your users can not see it and also to change the binding votes to zero, so it is not included in the data file that is submitted when the form is complete.

How to count the number of conditionally highlight cells in a column or row
I'm working on a table to identify problems with my credit rating. So, I have a column that indicates the due date on the invoice and G that contains the date to which I made the payment.
I'm trying to follow how many times I'm late with payments. I want to improve.
So if the G column is later than column D, both with the Date formatting. So, now I've highlighted cells and I want to summarize for the year, how many times I was late payments.
I thought a column G to count the number of days before or after that back I was with payments. But if the sum, it only gives me no useful information. I guess I could count the number of cells with values less than 0.
I prefer to be able to put in the summary column for G something that said 0-12 years ago has highlighted cells in the column.
Thank you
You can not count based on sharing or formatting. You can, however, be based on the same conditions.
There are functions:
COUNTIF() counties based on a condition is true
and
COUNTIFS() based on several conditions being true
= NB. If
Here is a way. IT will take an additional column that calculates the "delay" in the days of a payment
the first two lines are the lines of header
H3 = IF (COUNTA (D3, G3) > 1, MAX ((G3−D3) DUR2DAYS, 0), "")
It's shorthand dethrone select cell H3, and type (or copy and paste it here) the formula:
= IF (COUNTA (D3, G3) > 1, MAX ((G3−D3) DUR2DAYS, 0), "")
Now select cell H3, copy
Select the H3 cells at the end of column H, dough
H1 = "payments late =" & COUNTIF(H,">0")

Count the number of zero terms between non zero terms
Hello. I have a table of data of zero and nonzero (example: {1 2 56 2 3 0 0 0 0 0 2 3 5 2 3 5 2 0 0 0 0 32 43}) I need to count the number of zeros of each string of zeros and mark that number against the first zero no term following the string of zeros (NOTE (: string is used here as a description of a series of zeros, not a string variable). So the plot which coordinates since my example would be (5.2) and (4.32).
I'm clear on the way to the path, but I am unable to store only each final count of consecutive zeros without having unnecessary data in my plot.
Thanks in advance to all those who have advice!

Do something like that?
EDIT: Minor Correction because of the additional function of decrement.

Hello
I use Analogtodigital.Vi to convert the pulse of the sequences in digital.signals.I am able to get the representation of digital waveforms of impulses.
But how to count the number of 1 is present in the converted digital waveform. I want to count the number of 1 is present in the digital waveform converted.
Thanks in advance.
Have you tried the block scheme of similar to the Digital.vi of opening?
It creates an array 2D uncompressed 1 and 0, which is the binary 16 bits A/D conversion of each element in the array Y of the input waveform. You can use the DWDT digital Array.vi Boolean to convert a 2D Boolean table. Then convert Boolean values to 1.0 and summarize the array of integers. The sum must be the number of 1 bits in the digital waveforms.
Lynn
Note: The VI attached is saved in version 8.6. When I have it saved for the previous Version a warning was generated about the possible differences in the versions. Let me know if it doesn't work, and you are using which version of LV.

How to count the number of updates in a loop Forall
Hi friends
I want to know is - it possible to count the number of updates occurred in FORALL. I share the codes below. His only return the iteration number. If I spend 5 through the values of the PARAMETERS and 2 updates the values in the table then return 5 instead of 2. My requirement is to count the number of updates have taken place and return this value to OUTPUT parameter. If possible, please share codes. Thank you very much...
CREATE OR REPLACE PROCEDURE UPDATE_PROCESS_RATE ( V_HOSPITAL_ID IN HOSPITAL_SERVICE_MASTER.HOSPITAL_ID%TYPE, V_USER IN VARCHAR2, V_DATE IN DATE, V_PROCESS_ID IN VARR_ARRAY, V_PROCESS_RATE IN NUM_ARRAY, V_NUM OUT NUMBER ) IS V_ERROR_CODE NUMBER(15); V_ERROR_MSG VARCHAR2(200); V_ARRAY_ID NUMBER(10,2); V_TOTAL NUMBER:=0; BEGIN SAVEPOINT Sp1; BEGIN FORALL i IN V_PROCESS_RATE.FIRST..V_PROCESS_RATE.LAST UPDATE HOSPITAL_SUBSERVICE_PROCESS M SET M.PROCESS_CHARGE=V_PROCESS_RATE(i) WHERE M.HOSPITAL_ID=V_HOSPITAL_ID AND M.HOSPITAL_PROCESS_ID =V_PROCESS_ID(i); FOR i IN V_PROCESS_RATE.FIRST..V_PROCESS_RATE.LAST LOOP V_TOTAL:=V_TOTAL + SQL%BULK_ROWCOUNT(i); End loop; COMMIT; V_NUM:=V_TOTAL;
IndiMinds wrote:
But my requirement is: it must count the update only when it detects a different value from array. When it detects a different value in the table must be updated and count it and if the update of the table value is similar the TI should not count it.
For example, if the V_PROCESS_RATE table have these 3 values (10,20,30) and we need to update these 3 values with (10,40,50), so no update, it should return is 2 not 3.
Thank you
And then don't update these lines, change your update statement
UPDATE HOSPITAL_SUBSERVICE_PROCESS M SET M.PROCESS_CHARGE=V_PROCESS_RATE(i) WHERE M.HOSPITAL_ID=V_HOSPITAL_ID AND M.HOSPITAL_PROCESS_ID =V_PROCESS_ID(i) AND DECODE(M.PROCESS_CHARGE,V_PROCESS_RATE(i),0,1) = 1;

How to count the number of updates in a loop?
Hello world
Warm greetings
I'm using Oracle 11 g. I want to count the number of updates inside a loop. If updating not only one value in the table, then it should return 0 otherwise, it should count the number of updates and return it. I used SQL % ROWCOUNT, but returning an incorrect value.
I share the sample codes.
procedure proc1 (vid IN Number, vprocessId IN varr_varray, vCharge IN vnum_varray,vcnt OUT) IS vFlag Number(3):=0; Begin vflag:=vprocessId.FIRST; If vflag is not null then For vprocessId.FIRST..vprocessId.LAST Loop Update table set colCharge=vCharge(i) where colId=vid and colProcessId= vprocessId(i); End Loop End;

SQL to count the number of days of January with a range of dates
I have data like this, how to calculate the number of days with January in this date range.
BEGINNING END DAYS OF JAN 12/12/2013 20/01/2014 20 21/01/2014 02/02/2014 11 Hello
So, you want to count the number of days between
(a) either start_dt, or January 1, 2014 (prevailing later) and
(b) or end_dt or January 31, 2014 (whichever comes first).
However, if start_dt and end_dt are prior to January 2014 (or both are later) which will result in a number negative if you take the difference or 0, if it is higher.
This looks like a job for the GREATER and LESS than functions.
SELECT start_dt - START is not a column name good
, end_dt - is neither END
BIGGER (1 + LESS (end_dt, DATE ' 2014-01-31'))
-Most GREAT (start_dt, DATE '' 2014-01-01)
* v
) AS jan_days
FROM table_x
