Simple Function Help - Counting the amount of a certain value in a table.
I have a table of data, what function will I use to work out how many, for example 'dfjhg' there are, or how many 'B 4' there are.
Hi iMac '08,
Welcome to Numbers discussions.
The answer is =COUNTIF(cell range,"enter what you're counting for")
That should get you in the correct direction.
Also allow me to suggest you looking in Numbers Help for Statistical Functions.
These Discussions are enduser helping enduser, not Apple employees answering questions. Questions will be answered when a enduser such as yourself finds time, desires to, knows the answer along with the time to respond.
Again welcome to Numbers discussions, have fun here.
Sincerely,
RicD

How do you count the multiple columns of a field in a table

Whenever you have a problem, 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 (e.g., 11.2.0.2.0).
See the forum FAQ: https://forums.oracle.com/message/9362002
"Field" isn't a standard database term. Some people say "field" when they mean "column", but I don't think that's what you mean ("How do you count the multiple columns of a column .."). Do you want to know how many times a column is used (as opposed to NULL), or the number of different values in a column? You really need to show what you want. -
Counting the amount of like elements in an array
Hi,
I am very new to labview and would be grateful if anyone could help with the following.
I have an array of data and each element contains one of the integer values 0,1,2 or 3.
I want to be able to count the number of times each of these occur. ie 3 occurs 10 times etc.
This is probably a really simple problem but I cannot figure it out and would appreciate any help.
Thanks,
MariaHere's a more detailed version containing function labels so you cna recognize them better. It should be easy to built.
This is basicallly a general integer histogram function and can easily be adapted for larger (and smaller) selections (e.g. if the possible numbers are 0..999 you would initialize an array with 1000 elements of zero and everything else would stay the same.
If the possibilities are e.g. -5..5, you would use an array size of 11 and add 5 to each element.
All clear?
(Nick's solution would need to be rewritten whenever the number of tests changes and would be unmanagable for dealing with 1000 elements )

User defined function to check the NULL and 0.00 value in a Amount field
Hi Experts,
I have one scenario in which i have amount field in Data type.
I have to create one UDF which will do the following thing.
1. If the amount field is Null it should throw an exception in mapping.
2.If the amount field is 0.00 it should throw an exception in mapping.
3. For all other cases it should pass the amount value to the target.
Can anyone provide me the code For this UDF.
Thanks in advance.Hi,
You can add this logic to the UDF. Here var1 is the input string.
java.math.BigDecimal b=new java.math.BigDecimal(var1);
if(b.compareTo(new java.math.BigDecimal("0.00"))<=0)
//write your logic for values less equal to zero
One small request, if you think your question has been answered, properly and correctly, could you please kindly if possible close down this thread. It helps people who look for solutions to similar problem.

How to count the amount of registries of a grid?
Hi, I have a grid generated through a HTTPService, Example:
<mx:HTTPService id="userRequest" url="
http://localhost/flex/php/prueba2.php"
useProxy="false" method="POST">
<mx:request xmlns="">
<userid>{userid.text}</userid>
<username>{username.text}</username>
<emailaddress>{emailaddress.text}</emailaddress>
<id_operacion>{txtOperacion.text}</id_operacion>
</mx:request>
</mx:HTTPService>
<mx:DataGrid id="dgUserRequest" x="22" y="10"
dataProvider="{userRequest.lastResult.users.user}">
<mx:columns>
<mx:DataGridColumn headerText="User ID"
dataField="userid"/>
<mx:DataGridColumn headerText="User Name"
dataField="username"/>
<mx:DataGridColumn headerText="Email Address"
dataField="emailaddress"/>
</mx:columns>
</mx:DataGrid>
how I can obtain the amount of registries that has my grid?
jfuentesAlso, be aware the the default for HTTPService is
resultFormat="object". this causes your XML to be converted into a
nested object structure.
I advise you keep your data as XML. It is much easier to work
with (search, etc) than the nexted objects. specify
resultFormat="e4x".

Count the number of a certain document type in a document-set
The Content types allowed in my Document-Set are document type A and document type B. How can I count the number of document type A in the document-set with workflows? I need to know if there is at least one document of type A inside the
document-set. With “Item child count” condition in workflows I can only count the total number of the documents and not the number of specific document type.Hi pax123,
According to your description, my understanding is that you want to count the number od the documents based on Content Types.
As a workaround, you can create two columns to store the count of documents for your two content types. Then create a loop action to loop all documents, if content type is equal to your content type A, do a calculate to plus 1 to the numberA, then update
the column numberA. Do a same if condition in the loop for your content type B.

How to Count the number of TAB chars value '0A' in a line?
I have a requirement to count the number of TABs in a text file that I am processing (they must equal 75) to ensure that all the fields have been submitted on the file I am reading?
How do I identify the TABs in a line?
I have this so far:
CONCATENATE gv_unix_file gv_lstfiles-name INTO gv_unix_file.
OPEN DATASET gv_unix_file for INPUT IN TEXT MODE ENCODING NON-UNICODE.
IF sy-subrc <> 0 .
message e000(zz) with 'Cannot access in_uk files'.
ENDIF.
CONCATENATE gv_unix_file_arc gv_lstfiles-name INTO gv_unix_file_arc.
OPEN DATASET gv_unix_file_arc FOR OUTPUT IN TEXT MODE ENCODING NON-UNICODE.
IF sy-subrc <> 0 .
message e000(zz) with 'Cannot access in_uk files'.
ENDIF.
DO.
READ DATASET gv_unix_file into lv_str.
IF sy-subrc <> 0.
exit. "exit do loop, file is done.
else.
TRANSFER lv_str to gv_unix_file_arc.
ENDIF.
ENDDO.Here is a sample code:
DATA: lv_string TYPE string,
lv_tab TYPE c VALUE cl_abap_char_utilities=>horizontal_tab,
lv_i TYPE i.
DATA: result_tab TYPE match_result_tab.
DO 3 TIMES.
CONCATENATE 'A' lv_string INTO lv_string SEPARATED BY lv_tab.
ENDDO.
" this is how you need to find how many tabs are in your transfer work area...
FIND ALL OCCURRENCES OF lv_tab IN lv_string RESULTS result_tab.
DESCRIBE TABLE result_tab LINES lv_i.
WRITE:'No. of tabs found:', lv_i. -

How do you count the amount of times a button is clicked?
Heres my code:
public void buttonClicked(JButton buttonzilla){
if(buttonzilla == startButton){
while(i < 7){
story.append("\n" + "\n" + abc);
i++;
However, when i click the button once, it displays all elements in the array, however, im trying to get it so that each time i click the button another element is displayed, one at a time. How would i go about doing this?Can you explain the code because it dosent make sense
to me, im a beginner.In the code you posted, there is no declaration for the variable i, so I've assumed it is declared as a class variable, and has scope within the class.
You say you want to add only the data from the element of abc[], relative to the number of times the button has been clicked i.e. 1st click adds abc[0], 2nd click adds abc[1] etc.
if(i < abc.length) - to ensure no ArrayIndexOutOfBoundsException (really should also check i is not negative)
story.append("\n" + "\n" + abc[i++]);
instead of
story.append("\n" + "\n" + abc);
i++; -

Conditionally executing a function based on the existance of an item value
I want to populate a field based on a function. Easy enough with a function I have created to do this.
GET_A_VALUE(:P14_ID);
This works nicely when I put that in the default value and then go and edit an existing record.
The problem is when we try and create a new value. :P14_ID does not exist
I get something like this
ORA-01403: no data found
Error ERR-9132 Error in PLSQL expression for item default code, item=P14_ID
OK
Which makes sense as P14_ID doee not exist yet.
I've tried to do something like this with no luck in the default field
begin
if :P14_ID is NOT NULL
then GET_A_VALUE(:P14_ID);
end if;
end;
Which gets me this
ORA-06550: line 3, column 6: PLS-00221: 'GET_A_VALUE' is not a procedure or is undefined ORA-06550: line 3, column 6: PL/SQL: Statement ignored
Error ERR-9131 Error in PLSQL function body for item default code, item=P14_ID
OK
Am I approaching this in the correct way? Any suggestions?I would have thought his function would look more like this:
FUNCTION get_Value(p_val IN NUMBER)
IS
l_ret VARCHAR2(1);
BEGIN
SELECT dummy INTO l_ret FROM dual WHERE 1=1;
RETURN l_ret;
ENDWhen in fact it should look something like this:
FUNCTION get_Value(p_val IN NUMBER)
IS
l_ret VARCHAR2(1);
CURSOR i IS SELECT dummy FROM dual WHERE 1=1;
BEGIN
OPEN i;
FETCH i INTO l_ret;
CLOSE i;
RETURN l_ret;

Need help with SQL Query (query for certain IDs in a table and then IDs not in result set)
OK. This is hard to explain but that may be my problem in constructing the query.
I have a table that has a list of jobs. The jobs information in this table, among other things, is a short description of the job itself (think "title" in phrase form), date, and ID.
So I can query the table to get all the jobs for a particular grouping of IDs (the only ones I am interested in) that ran successfully for a given time period. But what I want are all the jobs that did not succeed (or therefore are not present in the table) for this group of jobs and for a certain date range. But these are not the only job id's in the table.
To get the successful ones I do the following:
SELECT id,short_desc FROM my_table where
id IN('1230', '1231', '1232', '1239', '1244', '1245',
'1246', '1247', '1248', '1272', '1280', '1281', '1282',
'1283', '1284', '1285', '1286', '1249', '1250', '1251',
'1252', '1253', '1255', '1233', '1234', '1235', '1236',
'1237', '1238', '1256', '1257','1258', '1254', '1290','1310')
AND the_date > = SYSDATE - 23/24
AND to_char(the_date, 'DD-MON-YYYY') = TO_CHAR(CURRENT_DATE, 'DD-MON-YYYY')
I have tried to use another AND clause with NOT IN and the group or NOT EXISTS but that doesn't work as there are other jobs captured in this table with id's of course. I am only concerned with these id's:
IN('1230', '1231', '1232', '1239', '1244', '1245',
'1246', '1247', '1248', '1272', '1280', '1281', '1282',
'1283', '1284', '1285', '1286', '1249', '1250', '1251',
'1252', '1253', '1255', '1233', '1234', '1235', '1236',
'1237', '1238', '1256', '1257','1258', '1254', '1290','1310')
Someone said to use a temp table. I don't think I have permission and I haven't tried as I want to do this in one query if possible.
After thinking about this I am at a loss. I tried to do this in the front end but it just became too messy.You do not need a physical temp table. You need an in-line view:

Using RowID to get the first instance of a value in a table
I have a table of the structure
SECURITY(
COMPANY_ID NUMBER,
SECURITY_ID NUMBER,
CUSIP
One company can have many CUSIPs asociated with it and I want to find the best way to find any valid CUSIP for the company_id using PL/SQL.
Here is my approach, I would like any other suggestions or comments.
SELECT
rowid INTO v_row_id
FROM
SECURITY
where COMPANY_ID=v_company_id
and rownum<2
SELECT
CUSIP INTO v_cusip
FROM
SECURITY
where rowid=v_row_idHello
If you don't specify an order you will let oracle decide what the "first" row is. It may be the first row that was inserted, it could be the last, or it could be any other row for that company. If the execution plan for the query changes (or a number of other things) the first row returned could change. This may of course not matter to you at all but it's worth pointing out I think:
create table dt_test_SECURITY(
COMPANY_ID NUMBER,
SECURITY_ID NUMBER,
CUSIP varchar2(20)
--generate some test data
SQL> insert into dt_test_security select mod(rownum,200)+1,mod(rownum,10)+1,to_char(rownum) from dba_objects where rownum <2001;

1000If you use MAX(cusip), you will get the highest cusip against the company which is much more specific. Is that what you want? How are you intend to determin which is the first row, or doesn't it matter?

What function can be used to count the number of cells who have a specific string (i.e. "Blue")?
I am attempting to gather information as to the makeup of the cars in a parking lot. I have already gathered data as the make, model, and color of the care on each car. How would I go about counting the amount of cells which 'red' or 'honda'?
Do you know that iWork Formulas and Functions User Guide is not delivered to help users to help you ?
So, download it and search for the keystring COUNT
I bet that you will find quickly the functions COUNTIF and COUNTIFS.
