TableView Control(finding total no of Rows & Columns)
Dear ALL SDN Members,
Please tell me the method by which we can obtain total no. of rows and columns in TableView control.
Hi,
You can use Describe internal table to find the Number of Rows in the table control.or tablecontrol-lines will give the number of rows.
for getting the number of columns you have to call the FM <b>REUSE_ALV_FIELDCATALOG_MERGE</b>
data: v_lines type i.
call function 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
I_PROGRAM_NAME = sy-repid
I_INTERNAL_TABNAME = 'ITAB'
I_INCLNAME = sy-repid
changing
ct_fieldcat = IT_FIELDCAT
EXCEPTIONS
INCONSISTENT_INTERFACE = 1
PROGRAM_ERROR = 2
OTHERS = 3
if sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
endif.
describe table it_fieldcat lines v_lines.
now v_lines will have the number of columns.

Find Total Number of Rows in Database
I am trying to find total number of rows in Database? Thanks in advance
I'd come back to a question of "why". What possible reason could you have to want to know the number of rows in every table in the database?
This seems like it is a request from someone non-technical where they're not sure exactly what they need to ask to get the information they want. I'm forseeing something along the lines of
User: How many rows are in the database
DBA: Ummm.... <<goes off and spends a lot of resources to count>>> ... 1 billion.
User: Wow, that's a lot... How big are those rows...
DBA: Hmmm... <<goes off and spends more time trying to find an average row size>>... 100 bytes
User: <<Plugs numbers into Excel>>... OK, our database is 93 GB, so we need to order 100 GB of disk for our new environment.
DBA: <<Months later, after 100 GB of disk has been budgeted, purchased, and delivered>> User, you didn't order enough disk for our disaster recovery environment.
User: You said our database was only 93 GB!!
DBA: 93 GB of data. Plus 100 GB of indexes, TEMP, UNDO, space for archived logs, ...
When "odd" requests come down, it's generally the case that the person asking the question doesn't know what question they really want to ask because they don't have the domain knowledge to know how to ask the question. Walking over and asking them what they're hoping to accomplish/ what they're using the data for generally leads to a case where
- The user gets exactly the information they need, not the information they think they want
- The DBA does a lot less work, since the right question is almost always easier to answer
- The user thinks of the DBA as a really helpful sort of guy and remembers how helpful you were in the past when you have to push back on other things later
- No one ends up playing the blame game when the user gets just what they asked for and not what they want.

Formatting the total row column for a OATableBean
Hi,
I have an OATableBean with total row column.
I need to format one column and it's total value as 28,861.972528.
I used both codes below:
1-
Formatter formatter = new OADecimalValidater("###,###,##0.00000;-###,###,##0.00000", "###,###,##0.00000;-###,###,##0.00000");
OAMessageStyledTextBean unitBean = (OAMessageStyledTextBean)webBean.findChildRecursive("UnitLandedCost");
if(unitBean != null)
unitBean.setAttributeValue(ON_SUBMIT_VALIDATER_ATTR, formatter);
2-
DictionaryData unitBeanFormat = (oracle.cabo.ui.data.DictionaryData)tableColumnFormats.getItem(pageContext.findChildIndex(tableBean, "UnitLandedCost"));
f(unitBeanFormat != null)
unitBeanFormat.put(ON_SUBMIT_VALIDATER_ATTR, formatter);
Both codes worked for the values, but the total value was not formatted in both cases. I tried to use the code below to get the column Footer, but the tableFooterBean is null:
OATableFooterBean tableFooterBean = (OATableFooterBean)tableBean.getColumnFooter();
Is there anything else that should be done to format the total value?
Thanks and Regards,
AndreaAs Tapash mentioned getTotalValues method will work. Another option can be to calculate the total value based on the rows of VO but that won't be required unless you are looking for Grand Total functionality.

In the old version of Numbers (09) as well as in the same Pages version I could choose to allow to mark single lines inbetween rows/columns in order to choose to create different types of lines to mark separations in different sections or just single cells within a table, how do I do that in the recent upgrade?!!! I´m going mad over here!!!!!
Hi A-S,
Do you mean Cell Borders in the Format Panel?
To create this?
Or if you want borders under only A5 and C5 (but not B5) command click on those cells to select them before applying the borders in Format Panel

I'm attaching a file that may help. Just remember this is my FIRST attempt at using NI/FeildPoint so things that would be obvious to the normal users more than likely would slide right by me. So I'll try and explain what the text contains as to make my problem more clear. I'm using a FP-1000, FP-AI-100, and a FP-TB-10. i'm creating a application where I'm using the 8 channels from the FP-AI-100 to monitor a control system ,that we manufacture. The control system is in an environmental chamber. I use the FP-TB-10 to monitor the temperature while in the chamber. The control system is ran for 4 hours under varing enviromental conditions while I monitor vital system voltages with the FP-AI-100. Now the application that i'm building starts with the obvious FP CREATE.VI and so forth I have no problem communicating with the FP's, but the information that I'm monitioring needs to be placed into a file with Headers describing the information below it. Now I use a "WHILE LOOP.VI" to monitor the FP-AI-100 & FP-TB-10 for the 4 hour period. but before that I create and open a file where I use a "CONCATENATE STRINGS.VI" to enter the headers I need. I do this by CONSTANTS, CONTROLS, TABs, AND CARRIAGE RETURN being entered into the "CONCATENATE STRINGS.VI" in the order I want them to appear. I use ROW 1 to enter (OPERATOR:with a CONSTANT) an a (CONTROL so the operator may enter his name and be recorded into the file) using a TAB to seperate Columns and a CARRIAGE RETURNto drop down to ROW 2 for the next headers. I use header names and TABs to seperate the columns. This part works great. I end up with ROW 1 having the operator information then ROW 2 having the headers for all the channels I'm using to monitor the control system with in their own column. The trouble happens when I write to this file during the "WHILE LOOP". The information recorded for DATE:, TIME:, and Channel 0 of the FP-AI-100 end up right under their corresponding header on ROW 3, but the rest of the data ends up on ROW 4 in column 3 and goes down many rows with some of the data not being stored at all. It varies on how many rows are used starting at ROW 4 but hey always stay in column 3. I use the "FP READ.VI" outputing to a "ARRAY TO SPREADSHEET STRING.VI" outputing to a "CONCATENATE STRINGS.VI" for each channel within the "WHILE LOOP" then into the "WRITE.VI". I use the "CONCATENATE STRINGS.VI" to place my data OR atleast I thought you could do that some how I'm not quit doing something write either there is a sampling/timing issue or writing to file issue where things are being confused in the "WHILE LOOP" if someone know a better route to perform what I'm tring here I would be interested. Its not like I'm not giving it the old colledge try here but without proper training and the vagness of the manuals it's difficult to understand what every connection actually does.I'm tring though for everyone who happens to fill pity for me
Thanks for your help

Allmost right. The 8 channels come out as 1D-array, ch0...ch7.

I don't use this Spreadsheet VI, because files coming out there allways
start this time consuming EXCEL wizzard. Because of this, I programmed my
own CSV-conversion vi. Maybe you could just use a common texteditor, like
wordpad and put the csv-examples from my last reply down to a text file
and rename it to *.csv. Texteditors terminate lines with "\r\n" by
default, so this is a very quick way for testing.
> FP_Analog_Logging example to record all eight channels it uses a Array
I didn't find the vi you metione above, but there is another good one:
Look at examples\FieldPoint\DataLogging\FP Logger.vi.
In a little case structure, at "false", there is a function called "Format
into string".
Pop up on the format string and adjust >>'\' Codes Display<<.
Then you change the format string into: %.;%-f%s
A Tab string is connected to the lower input of this function. Replace
this one with a comma.
That should do.

Yes, just as explained above. If you put a indicator at the output to
display the values, you can expand the display to show all 8 channels, but
you can't name induvidual cells. In a array, all cells have identical
named labels. If you want to name the individually, you have to attach the
array to cluster function and put the indicator after this one. Enable
labe display and name the output values individually.

Explained above.

Well, modifying strings are done with string functions.
Above, as I explained how the sample FP Logger.vi can be modified to do
the job for numbers. The pre- and suffixing with ", you only need for
strings, which EXCEL should interpret a string and as nothing else as a
string, even if there's a number inside. You usually need this only for
headers. So its easyest, if you just write your string into a string
constant or control and concatenate it to the previous csv-file contents.
Oh, I just see by looking at the above mentioned example... Inside the
case structure, but in the "true" case, there are error messages
concatenated to the logfile. At this point it is importent, to use " for
integrating the message into the CSV file, because a error message usually
looks like this: >> ERROR 2345 in vi yxz <<
Here you have text and number strings mixed in one line. EXCEL does not
know, if it should interpret the number inside the error line as separate
number, separating the line into three colums i.e. string before number,
number and string after number. So tell EXCEL by putting a " before and
after the line each.
For this, expand the Format To String function by one input, move down all
connections, to be able to insert a string constant with a " to the first
argument connector. Change the contents of the string constant at the
bottom argument from tab to ", (quotation mark AND comma)

The example I mentioned above help here to.
Look at the Write File function. This function receves data from a
function named concatenate strings. Expand this function to have one more
spare input at the bottom. Create a string constant. Switch the constant
display to "\" mode. Enter "col0","col1","col2"\r\n into the constant.
Connect the constant to the spare input.
Doing this, every dataline in the csv file is followed by
"col0","col1","col2"\r\n .
I wish you a nice weekend,

Having problem with two Tableview controls.
Hi all,
I have two tableview controls in my page. TV1 has list of employees. TV2 is populated with details based on the employee selected in TV1.
The actual problem is, in TV1 when i goto next page using navigator and select an employee in 15th row, and select a detail row from TV2, TV1 gets refreshed and goes back to row 1.
How can i avoid this?
Thanks & Regards,
LalithHi,
you can bind the attribute of the tableView selectedRow = "//model/selected_row"
to an attribute in your model class
that way you can always find your selection if working stateful

Query regarding onNavigate method in a tableview control
hi all,
i am using a tableview control in jspdynpage to display the sales order details using the standard BAPI that is BAPI_SALESORDER_GETLIST.
following is the flow:-
i enter the customer number and the sales organization in the first i-view.
it interacts with the backend and brings the data into a tableview control in the second i-view.
the problem i am facing is:-
when i click on the navigation button of the tableview control instead of showing the next row of records, it takes me back to the previous i-view.
please help as i am unable to find the error myself.
i can post the code if you want.....

Can I create a generic Point to Row Column function?
I have a VI with multiple MultiColumn Listboxes in it. One way I've seen to make the entries writeable is as follows:
This works fine. The only issue is that to get the 'Point to Row Column' (PtRC) method requires (as I understand it) right-clicking on the MCL and selecting that method.
I have multiple MCLs, and I wanted to create an event structure that was generic and could process any of them the same way. But the problem with that is that I don't know a way to get access to the PtRC method for each one. The only way I know to do it would be to use VI Scripting to create the reference on the fly (not sure if that would even work), but even if that works for me, I don't think it will work with the free LV RunTime Engine (my experience is that you can't use the RTE to execute any VIs that utilize VI Scripting).
So my question is, is there a way to get a reference to the PtRC method - generically - without using VI Scripting, and/or is there a different way to do what I'm trying to do here (i.e. make the MCL writeable by the user and have it retain the values the user writes to it during VI execution).
thanks
Solved!
Go to Solution.Not generic enough for you (not sure why it wouldn't be) here we can have code that finds the Multicolumn Listboxes and registers for all of them.
Edit: As I feared the snippet isn't exactly what I made. The "This VI" control on the left should be the "This VI" constant.

To find longest match in a column
In my project i want a query to find out longest match in column (code) with variable (calledstation).
Table: Ratelist
code country rate
1150 US 1.25
1025 US 1.20
1 US 1.0
Range of calledstation: 10 - 12 digits
eg:
calledstation = 11504578957
To find the longest match code should be compared with calledstation.
For the eg above the resultset should be the 1st row which contains code = 1150
because 1150 is longest match of 11504578957.
Result:
code country rate
1150 US 1.25
And if Ratelist table does not have row corresponding to 1150 then the resultset should contain row correspondence to code (1).
code country rate
1 US 1.0Something like this?
SQL> define calledstation='11504578957'
SQL> with RATELIST as(
2 select '998' code,'5.0' rate,'UZBEKISTAN' country from dual union all
3 select '61','2.5','AUS' from dual union all
4 select '44','1.5','UK' from dual union all
5 select '1150','3.0','US' from dual union all
6 select '1123','2.0','US' from dual union all
7 select '1','6.0','US' from dual)
8 select MAX(code) KEEP(dense_rank LAST ORDER BY length(code)) code
9 from ratelist

Format the total value in the column of the graph table
Hello all,
I have a graph table and I need to format the total value in the column of the table.
I am trying to find my table bean with the code below but it's not working in the processRequest. Is there anything else that should be done?
// Get the graph
OAGraphTableBean graphBean = (OAGraphTableBean)webBean.findChildRecursive("MyGraph");
// Get the table
OATableBean tblBean = (OATableBean)graphBean.findChildRecursive("MyTable");
The tblBean is null in the processRequest. In the processFormRequest the tblBean is not null.
Thanks and Regards,
AndreaHi,
The code OAGraphTableBean graphBean = (OAGraphTableBean)webBean.findChildRecursive("MyTable"); does not work because in this case I am getting the table but casting to a graph.
The MyTable bean is a child of MyGraph.
When creating a graph bean we have the option to create a table as a child (select your graphTable region in the Structure pane, and choose New > tabularFormat - to create the table).
The table bean child I can get just in the processFormRequest, but the graph I can get in both processRequest and processFormRequest.
I need to get the table bean in the processRequest to format the total value column.
Do you know if is there anything else that should be done to format the total column?
Thanks and Regards,

How to find total recs in a local table for a particular condition
Hi,
How to find total recs in a local table for a particular condition?
Thanks,
CDWell, you may want to try this as well, and compare to the LOOP way. Not sure what kind of overhead you may get doing this way. Here ITAB is our main internal table, and ITAB_TMP is a copy of it. Again I think there may be some overhead in doing the copy. Next, delete out all records which are the reverse of your condition. Then whatever is left is the rows that you want to count. Then simply do a LINES operator on the internal table, passing the number of lines to LV_COUNT.
data: itab type table of ttab.
data: itab_tmp type table of ttab.
itab_tmp[] = itab[].
delete table itab_tmp where fld1 <> 'A'.
lv_count = lines( itab_tmp ).

Trying to find the number of rows in a ResultSet
I am trying to find the number of rows in a ResultSet, using the following code:
rs = st.executeQuery(query);
rs.last(); // to move the cursor to the last row
System.out.println(rs.getRow());
However, I am getting this error:
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unsupported method: ResultSet.last
Whats going wrong??praveen_potru wrote:
You might have not used scrollable result set..
Try like this:
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);rs = stmt.executeQuery(sqlString);
// Point to the last row in resultset.
rs.last();
// Get the row position which is also the number of rows in the ResultSet.
int rowcount = rs.getRow();
System.out.println("Total rows for the query: "+rowcount);
cheersAnd I hope the OP would read it because the thread is a year old. -
