How to know the number of rows of a ResultSet

Hello.
I'm trying to detect the number of rows of a query result before making all the results.next().
Until know, my way was:
ResultSet results = sql.executeQuery();
while( results.next() )
int i = 0;
... do stuff ...
i++;
out.println("The number of rows is: " + i);
But I would like to know the value of 'i' just after 'executeQuery'.
Does anybody have any experienc?
Regards.

How about like this???
>
ResultSet results = sql.executeQuery();results.last();
i = results.getRow();
results.first();
while( results.next() )
int i = 0;
... do stuff ...
i++;
out.println("The number of rows is: " + i);
But I would like to know the value of 'i' just after
'executeQuery'.
Does anybody have any experienc?

How to know the number of rows in a cursor?

Hi all,
How can i know how many rows a cursor has ?
Glen

dbms_sql... you can use when you want to know how many lines of code the cursor has.
If you want to know how many rows it will fetch, you have to fetch all rows - the number of rows actually fetched are assigned to the variable <cursor_name>%ROWCOUNT.
When you don´t want to fetch all rows, all you can do is count(*)...

How to get the number of rows in a ResultSet

Hello,
I'm an intern and I'm trying to get the number of rows from result set in oracle using rs.last() and rs.beforeFirst() methods
but I got an error. Could Below is my sample code:
import java.sql.*;
public class SarueckConnect {
public static void main(String[] args) {
Connection con = null;
Statement stmt = null;
ResultSet re = null;
String[] ParamArray;
ParamArray = new String[24];
//Properties logon;
try {
Class.forName("oracle.jdbc.driver.OracleDriver"); //Loading the Oracle Driver.
con = DriverManager.getConnection
("jdbc:oracle:thin:@258.8.159.215:1521:test_DB","data","data"); //making the connection DB.
stmt = con.createStatement ();// Sending a query string to the database
//stmt.executeUpdate("UPDATE test_table set steuk = 6 WHERE steuk = 5");
ResultSet rs = stmt.executeQuery("SELECT mandt,kokrs,werks,arbpl,aufnr,vornr,ile01,"+
"lsa01,ism01,ile02,lsa02,ism02,ile03,lsa03,ism03,ile04,lsa04,ism04,steuk,matnr,budat,"+
"kostl,pernr,rueckid FROM test_table where steuk =6");
//Print the result out.
rs.last(); //This is the line which gives an error.
int rows = rs.getRow();
rs.beforeFirst();// I presume this is wrong to.
ParamArray = new String[24*rows];
int counter=0;
while (rs.next()) {
for (int i = 1; i <= 24; i++){
ParamArray[i-1+(counter*24)] = rs.getString(i);
System.out.print(rs.getString(i) + '\t');
System.out.println();
counter++;
} catch(Exception e) {
e.printStackTrace();
} finally {
try
if(stmt != null) stmt.close();
if(con != null) con.close();
} catch (Exception exception) {
exception.printStackTrace();
TryBapi sap = new TryBapi(ParamArray);
}When I run the code I do have the following ERROR Message:
java.sql.SQLException: Invalid operation for forward only resultset : last
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)

at oracle.jdbc.driver.BaseResultSet.last(BaseResultSet.java:91)
at SarueckConnect.main(SarueckConnect.java:28)Please could any body Help me out here to figure out how to correct this?
Any Help would be highly apprecited.

make your result set scrollable...Not such a good idea. With Oracle, the JDBC driver will read and cache all the ResultSet in memory (with other DBMSs/drivers the behavior will probably be different, but you will still have some unnecessary overhead).
You can do the caching yourself if you think it's worth it. If the piece of code you posted is why you need this for, then use a List or Vector and you won't need to know the size upfront.

How to limit the number of rows in a smart form , sap script.

Can anyone tell me how to limit the number of rows in the output of a sap script/smart form. I have tried "protect/endprotect" in sap script but have no idea of how to do in smart form. In sap script the only way it has happened is by reducing the size of the main window.

Hi,
In Smartform also, why dont you try reducing the size of the window if you want to limit the rows in it. Also if you are printing Line Items in a LOOP, you can write
LOOP AT T_ITAB FROM 1 TO N in the LOOP Node if you know how many records exactly you want to display in 1 Page processing.

How to increase the number of rows in Status Oveview iView in MSS?

Hi
We have implemented MSS and have a question regarding Status overview iview.
The standard status overview iview of the team workset has 5 rows and we have to scroll using the arrow buttons to select/view a request.
Now can anyone explain me how to increase the number of rows in this iview? Is this somthing that has to be accoplished through web dynpro customization?
I checked the options in iView property and do not see any option to increase the number of rows.
please help
Thanks
-Michael

Hi Micheal,
Well, I am not really sure, if you could accomplish this using customizing, but I am sure that you can accomplish this using the JDI. Well, you can extract the application's source code using JDI and then change the required display rows property and republish it.
Am not really sure if this is suggestable method for this requirement,but it can be achieved using this JDI stuff.

How to increase the number of rows to be displayed in BEx Web Analyzer

hi,
I am viewing reports using BEx Web analyzer option. It is displaying only 24 rows of data at a time. How to increase the number of rows? do i need to any kind of settings?
pls reply.

Hi,
I think the standard template in 2004s is named 0ANALYSIS_PATTERN. You can find it in Web Application Designer, open, and search for the technical name. If you want to change the number of rows or columns, you can find this setting near the bottom of the XHTML view of the template:
<bi:BLOCK_COLUMNS_SIZE value="4" />
<bi:BLOCK_ROWS_SIZE value="17" />
Then just save, and ignore the error messages.

How to count the number of rows in a resultser object?

hi there
how to count the number of rows in a resultser object which may contains millions of rows? besides using a while loop? thanks

You don't, you execute a query whose result is the record count of those records that match the search and then you execute the actual query to create your record set. Typically you do
select count(id) from YourTable where [filter]
from the resulting ResultSet do
int res.getInt(1);
which gives you the count and then
select id from YourTable where [filter]
to produce the actual result set.
in the second query the id part can be substituted with the actual fields you want.

How do you return the number of Rows in a ResultSet??

How do you return the number of Rows in a ResultSet? It's easy enough to do in the SQL query using COUNT(*) but surely JDBC provides a method to return the number of rows.
The ResultSetMetaData interface provides a method for counting the number of columns but nothing for the rows.
Thanks

No good way before JDBC2.0. u can use JDBC2.0 CachedRowSet.size() to retrieve the number of rows got by a ResultSet.

[ASK] How to know the number of usage of each Atomic Service ??

I correct my question:
*How to know the number of usage of each Atomic Service by the Domain & Enterprise Services?*
I want to see the number of usage of each atomic service(AS) by other services (DS & ES)
ex:
es_A -----> ds_B   (1x)    ----->    as_B    (2x) --> so as_B is accessed by es_A twice (2x)
es_A -----> ds_C   (2x)    ----->    as_C    (2x) --> so as_C is accessed by es_A 4times (4x)
es_A -----> ds_B   (2x)    ----->    as_D    (3x) --> so as_D is accessed by es_A 6times (6x)
es_B -----> ds_B   (1x)   ----->    as_E    (1x) --> so as_E is accessed by es_B once (1x)
es_B -----> ds_C   (3x)    ----->    as_F    (2x) --> so as_F is accessed by es_B 6times (6x)
es_B -----> ds_B   (4x)    ----->    as_G    (1x) --> so as_G is accessed by es_B 4times (4x)
etc..
Is there any tool in OSB, WLS, BPEL Console or Java Developer to support it?
Thank you...

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??

Try like this:

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);

Need to know how to limit the number of rows returned on Oracle

MS SQL Server has a command called 'set row count'.
We are trying to find similar one on Oracle.
What we are trying to do is that instead of using rownum in the query statement, we would like to find way to limit the number of rows returned. I understand that we can use JDBC resultSet object, but that's not what we want.
I know Oracle has one called arraysize, but this would not limit the number of rows returned either.
Pease help.
Thanks

I understand that we can use JDBC resultSet object, but that's not what we want.I'm not sure which feature of ResultSet you use and which not.
But if this question has anything to do with JDBC (that's the forum where you put it), I'd recommend to use Statement.setMaxRows(). This will limit the count of rows which your statement will fetch into it's ResultSet.

How to limit the number of rows in the Custom Control box

Hi All,
In my Module pool screen I have a Custom Control box for providing some free text as input. Now, there is no limit in the number of rows allowed for this box.
But, the requirement is, it should have the maximum number of rows = 99. and each row should have maximum length = 60 characters.
User should not be allowed to enter more than 60 characters per row and more than 99 rows.
Could you please let me know how to do this..? Are there any methods available which controls the maximum number of rows and maximum length per row..?
Please help me in resolving the issue. Thanks in advance.
Thanks & Regards,
Paddu.

By "Custom Control Box", do you mean a Custom Container or a Table Control?
Anyway, I suggest you to use a table control (not a custom container as your requirement seems to be very precise on that point, maybe ask your client twice to make sure). Look at the examples of table controls in ABAPDOCU transaction.

How to determine the number of rows of data in a datatable?

I have a datatable that I fill from an SQL query. I do not know exactly how many rows of data it will return (due to my selection criteria) but will be somewhere between 100 and 300 rows. I send this data into a report but need to determine the length of the report (panel height data member) programatically based on how much data the query has returned. So, I need a way to count how many rows are filled in the data table.
I tried doing a nested "if" statement checking the value of each cell but when I tested the expression at 59 "if" statements (will need 300+) I got a parser error in lookout when I tried to accept the connection. I also tried a type of loop by assigning cursor.2 either to its own value (circular) or to its own value plus one depending on the value of the cell at cursor.2. It was close but overshot by one row or more (much more sometimes).
Any clever ideas? Perhaps I have just been looking at this problem too long. Thanks, in advance, for your help.

Since the datatable gets the data from the SQL query, you can also use the SQL statement to count the number of rows in the query result.
For example, in datatable you do "select localtime, trace1 from intdata where xxx". You can get the count by "select count(trace1) from intdata where xxx". Use the same condition in order to get the same number of rows.
Maybe another SQLExec object is needed to do the count.
Whenever the datatable executes the SQL, the SQLExec executes and return the count.

How to get the number of rows in a DB-Cursor

When i open a database cursor i do not know how much rows are stored in the cursor. To solve this problem i have to send a 'select count(1) ...' to get the number of rows before i set up the cursor. I think that this is not very clever and could possibly cause performance problems. But i need the num of rows to show the percentage of processed rows. Is there any other way to get the num of rows? May be by checking the cursor directly?
Please help!
Thanx a lot

In order to find out how may rows are going to be processed, oracle has to visit every row. So with a cursor, there is no property that will accurately reflect the number of rows until you get to the last one. That said, you could use
select count(*) over() as row_count, <rest of your columns> FROM <your table>
which will give you the total row count agaist each row in the result set. There are performance penalties involved but they will be less than issuing the query twice, once to get the count and once to get the rows.
Have a look on asktom for some very usefull info about all this.

How to get the number of rows written to the header of the spool file.

Hi
I need to create a header line for the spool file .
the header line should include fixed length values .
The header should include the number of records found in the table with a maximum begin date (begin_date is the column of the table)
To get the header in the spool file , i wrote a select query has :-
--SPOOL 'C:\Documents and Settings\abc\Desktop\output.TXT'
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000') ||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) ||
rpad(' ',76,' ')
from dad.school
group by sysdate;
SPOOL OFF
which gets me all the rows in the table , but i only want the rows with the latest school_begin_date .
how can i achieve that ...
I know that a subquery should be written in the from clause to get the number of rows found with a maximum school_begin_date.
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000') ||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) ||
rpad(' ',76,' ')
from dad.school where
select rownum from dad.school
where school_begin_date = max(school_begin_date) ;
the error i get is
ORA-00934: group function is not allowed here
I NEED HELP ..IN GETTING THE ROWNUM JUST FOR THE LATEST BEGIN_DATE ?
PLS HELP ME IN WRITING THE QUERY .
THANKS IN ADVANCE .

Try this:
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000')||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) || rpad(' ',76,' ')
from dad.school
where school_begin_date = (select max(school_begin_date)
from dad.school);
