How to get number of rows in tableview

Hello,
Could anybody help me on how to get the number of rows in a tableview? Sort of using DESCRIBE TABLE in classic ABAP.
Thanks,
Ricky

There is an attribute of the class CL_HTMLB_TABLEVIEW named
ROWCOUNT.
Inside an event u need to get this info use this code:
Replace 'Monitor' for the ID of your tableview
DATA: tv TYPE REF TO CL_HTMLB_TABLEVIEW,
      r_count type i,
      tv ?= CL_HTMLB_MANAGER=>GET_DATA(
      request = runtime->server->request
      name = 'tableView'
      id = 'Monitor' ).
      IF tv IS NOT INITIAL.
        DATA: tv_data TYPE REF TO CL_HTMLB_EVENT_TABLEVIEW.
        tv_data = tv->data.
        r_count = tv_data->rowcount.
      ENDIF.

How to get number of rows return in SELECT query

i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.

make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
         String sql = "select * from testing";
         PreparedStatement ps =
          con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
         ResultSet rs = ps.executeQuery();
         rs.last();
         System.out.println("Row count = " + rs.getRow());
         rs.beforeFirst();~Tim
NOTE: Ugly, but does the trick.

How to get number of rows

Hi!
Can someone tell me how to obtain the number of rows returned by a query?
I tried to use getFetchSize() but it seems to always return 0 for my query.
THANKS in advance!
ResultSet testRS = Stmt.executeQuery(testStmt);
int size = testRS.getFetchSize();
System.out.println("size = " + size);
Wo Lay

To get the number of rows returned, you have to loop
through the result set, or do a "select count" (which
is more efficient since it doesn't have to pass the
rows across the network) ...Looping around the entire result set is not very performance efficient. Then agin if you use count (*) you actually execute an extra query.
The best thing you can do is:// assume res is your result set.
res.last();
int rows = res.getRow();This way you only have to execute one query and you don't really need to loop around the entire result set. Of course you will have to have a scrollable result set, if this is supported by your DB.
Hope that helped.

I have no idea which component you're talking about. If want to discuss here about a non-Sun JSF component, then please mention about the name, version and build in detail. You can also consider posting this question at the website/forum/mailinglist of the component manfacturer rather than here. At least I can tell you that the Sun JSF h:dataTable has the 'rows' attribute for that. I can also suggest you to just take a look in the TLD documentation of the component in question. There should be all possible attributes listed with a detailed explanation about the behaviour.

How to count number of rows in table

can I get number of row in table except Count(*) in pl/sql
is there any other way

Also posted and answered here
how to count number of rows in table
count(*) will be the fastest way. It is only slow if the table has a vast number of rows, in which case why do you need to know the tables has 73552436467721 rows and not 73552436467737 rows. It doesn't seem to be much use. Either that or you are counting them a lot, which again seems rather pointless.

Jomar,
you can use Summary Columns in the Data Modell. Create them on group higher that your wished group (so on the pane for an first group of a query), use as Source the primary column and as reset at the group, where the summary column is located.
If you hide some instances via format triggers, that you could use a counter inside the format triggers to count the rows.

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 find number of rows in a table

i have one table ,it contains millions of record,how can i know number of rows in that table without using count(*),
i tried in user_table ,for the column NUM_ROWS,but it is not showing number of rows,pls send me a solution for this.
regards,
singh

Ok, that only was to show simply that max option
might not an option to reduce execution time.Yes, but I/O variances have a tendency to really skew the observed elapsed execution time - making execution time alone a poor choice to determine what SQL will perform better than another.
Both MAX(ROWNUM) and COUNT(*) results in the same amount of I/O - as both uses the exact same execution plan, I/O wise. In this example, a FTS.
SQL> create table testtab nologging as select * from all_objects where rownum < 10001;
Table created.
-- warmed up the buffer cache with a couple of SELECTs against TESTAB in order
-- to discard PIOs from the results
SQL> set autotrace on
SQL> select count(*) from testtab;
COUNT(*)
10000
Execution Plan
Plan hash value: 2656308840
| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 35 (9)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | TABLE ACCESS FULL| TESTTAB | 9262 | 35 (9)| 00:00:01 |
Note
- dynamic sampling used for this statement
Statistics
0 recursive calls
0 db block gets
131 consistent gets
0 physical reads
0 redo size
223 bytes sent via SQL*Net to client
238 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
1 rows processed
SQL> select max(rownum) from testtab;
MAX(ROWNUM)
10000
Execution Plan
Plan hash value: 2387991791
| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 35 (9)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | COUNT | | | | |
| 3 | TABLE ACCESS FULL| TESTTAB | 9262 | 35 (9)| 00:00:01 |
Note

So seeing that we have the exact same baseline for both queries, and that PIO does not influence the results, we time a 1000 executions of both.
SQL> declare
2 cnt number;
3 begin
4 for i in 1..1000
5 loop
6 select count(*) into cnt from testtab;
7 end loop;

This shows that what makes the MAX() more expensive is just that - determining the MAX(). For each row, Oracle has to call its internal MAX() function with two values - the current max result and the new value. This function then returns the new max value. This overhead per row adds up to a significant overhead in execution time - making the MAX() approach 5x slower than the COUNT() approach.
