How to get the number of columns in a result set???

hi everyone..
i am trying to establish a servlet applet communication....
my applet send the sql query to the servlet as serialised string and then the servlet executes the query...
Since i need to pass the result back to the applet, i thaught of passing the whole reult set to the applet..but that seems to be not possible..
so i thaught of storing my result set data in a vector and then pass the vector,but the first problem that i came across is that how to get the number of colums in a result set....
so is there a way to get the number of columns in a result set...???
and also i would like to know if it possible to send my whole result set to the applet bye serialization or by any method...???
thanx in advance

You shouldn't do. It expenses resources (you should always close the ResultSet and the Statement as fast as possible). Simply gently process it into a Collection or Map of DTO's. Those are serializable.

How to get the number of records of a streaming result set

Hi guys.
So if it wasn't a streaming result set, I would have done this:
{noformat}myResultSet<code class="jive-code jive-java">.last();
{color:navy}*int*{color} numResults = </code>myResultSet<code class="jive-code jive-java">.getRow();
</code>myResultSet<code class="jive-code jive-java">.beforeFirst();
</code>{noformat}
but being a streaming result set, beforeFirst() throws an exception...
So how do you get the number of records in that result set? I wanna avoid an extra count(*) query, so I would appreciate other solutions than that.

If you get an exception, then you surely have a stack trace. That should tell you what happens, or at least where.com.mysql.jdbc.MysqlIO.checkForOutstandingStreamingData(MysqlIO.java:2066)
Why do you need to know the number of elements beforehand, anyway?I need to know the number of elements because the incoming data goes into a table. Now of course, I could use ArrayList<String[]> or something, but wouldn't that require more memory resources than Object[][] ?
No one can tell you that, at least not without more information (say, the stack trace for example).Here's the exception message:
java.sql.SQLException: Streaming result set com.mysql.jdbc.RowDataDynamic@10c0ef2 is still active. Only one streaming result set may be open and in use per-connection. Ensure that you have called .close() on any active result sets before attempting more queries.

How to get the number of files currently open?

hi,
does any one know how to get the number of files currently open in windows OS?
e.g. lets say .txt files...
any comment will be really appreciated.
thanks

Assuming that you don't want to actually do this from within Java code (which would obviously require native code), here's a utility that will give you a list of which file handles are opened by which processes (on Windows):

How to get the number of elements in DB

Could you tell me how to get the number of elements in DB??
My code to get the number is below, but I think it is not efficient
DB->cursor(DB, NULL, &cursorp, 0);
while ((ret = cursorp->c_get(cursorp, &key, &data, DB_NEXT)) == 0)
count++;
--------------------------------------------------------------------------------------------------------------

Hi,
The most efficient way to get a count from the database is using the DB->stat API (http://docs.oracle.com/cd/E17076_02/html/api_reference/C/dbstat.html)
The code will be something like:
        DB *dbp;
        DB_BTREE_STAT *statp;
        int ret;
        /* Print out the number of records in the database. */
        if ((ret = dbp->stat(dbp, NULL, &statp, 0)) != 0) {
                dbp->err(dbp, ret, "DB->stat");
                goto err1;
        printf("%s: database contains %lu records\n",
            progname, (u_long)statp->bt_ndata);
        free(statp);The code comes from the example included in the distribution at examples/c/ex_btrec.c
If the database isn't a btree, you should update to the appropriate statistics structure and field.
It's worth noting that retrieving the count is never a "cheap" operation. The count is not stored in the database - since doing so introduced a single point of contention that creates a bottle neck.

How to get the number of messages consumed by a MDB ??

Hi all,
How to get the number of messages consumed by a MDB displayed in OEM in a Java Application ???
DMS ??? what use DMS ???
tanks

ok.
Well using DMS is one way to get at these sorts of stats in a programmatic manner.
There's a Java API you can use, or you could call out to the Spy servlet to query the DMS stats in either text or XML form.
I don't have an MDB published so I can't show you specifiically, but here's the sort of query you can use to extract the data.
http://localhost:8888/dms0/Spy?format=raw&table=oc4j_ejb_stateless_bean&recurse=children
Which produces a table of the TEXT form:
<DMSDUMP version='9.0.4' timestamp='1163456821185 (Tue Nov 14 08:57:01 CST 2006)' id='8888' name='OC4J'>
<statistics>
/oc4j [type=n/a]
/oc4j/default [type=oc4j_ear]
/oc4j/default/EJBs [type=oc4j_ejb]
/oc4j/default/EJBs/jmsrouter_ejb [type=oc4j_ejb_pkg]
/oc4j/default/EJBs/jmsrouter_ejb/AdminMgrBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 1 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 1 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
/oc4j/default/EJBs/jmsrouter_ejb/EnqueuerBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 0 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 0 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
/oc4j/default/EJBs/jmsrouter_ejb/TimerHandlerBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 0 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 0 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
</statistics>
</DMSDUMP>
Or produces an XML document of the form:
http://localhost:8888/dms0/Spy?format=xml&table=oc4j_ejb_stateless_bean&recurse=children
You can use the Spy console to find the table that contains the details for MDB and then take it from there.
This is not what you specifically want to do, but it does provide a good overview of how DMS is used.

How to get the number of bytes at TCP port

Hi all,
How to get the number of bytes to read at the TCp port...as someone had suggested in some forum we do read the number of bytes first and then pass this...
but we get a problem when we have FF data in this...because then it sends 2 FF data...and cause of this we skip the last data...is there any solution for the same?

Hi
In LabVIEW you don't have the same property as in serail port.
You havn't "Byte at TCPIP port".
if you developp a protocol, one soltion, is to send the size to read.

[Win VC++ 6.0 ]How to get the number of files count in a folder using VC++ 6.0?

Hi all,
Can any one tell how to get the number of files(.EPS) count inside a folder when the folder path is specified in VC++ 6.0?
Thanks in Advance.
Regards
myriaz

I'm a little confused by the question, but it sounds like you're asking how to count the number of files with a particular extension in a given directory? That's not really an AI SDK question, but it's a fairly easy one to find if you google it. If you're trying to use Illustrator to do it, AI doesn't have a general purpose file API. It has a few functions to do some things that Illustrator needs, but I don't think enumerating directories is one of them.

How to get the selected rows & columns in the table?

hi everybody,
In my application the table is kept inside the event structure.I select the cells in the table (using mouse) on running time.How to get the selected number of rows & columns in that table?

Hello,
You can fill selected values of the table by writing to it or the corresponding property using a property node - the table is just a 2D array of strings. I think for your "disable" question you are referring to the shortcut menu (when you right click). If you are using LabVIEW 8.x, you can edit or disable that shortcut menu - just right click on your table at edit time and choose Advanced >> Run-Time Shortcut Menu.

How to get the number of rows in a repeating frame ?

Hi all,
When I launch a report from forms then sometimes there are data in the report and sometimes there are no data. And the problem is that when there are no data then the frame containing the repeating frame is still displaying and a blank page displays on the report.
So I want to get the number of rows from the repeating frame so that I can code a format trigger on the frame to display or not the enclosing frame depending on the existence of data from the repeating frame.
Thank you very much indeed.

Dear Friend,
You can achieve this. Define a summary column (say cnt). Select summary type as "COUNT". select any one of columns that are getting displayed in your repeating frame as summary column and provide "reset at" group name (or set this to report if you are defining this field at report level) . This "cnt" variable will contain how many records that will be fetched for your repeating frame (i.e. Group of Repeating frame). You can use this "CNT" variable in your format trigger.
In this case there is no need to write before report trigger or anything.

Manish Trivedi

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 the row added to tabular form by the AddRow()

using 4.0. User clicks an Add button which calls a javascript function that gets a couple page item values, inserts a row (addRow(), and updates columns in that newly inserted row with the values from the page items. This works fine if I hard code the row number (so it saves the page item values into the row I specify) but I don't know how to get the row number of the newly inserted row?
i.e html_GetElement('f12_0003').value = DocName; will set the element F12 at row 3 correctly, but I need to have the 0003 replaced with a variable that has its value set after addRow() but can't figure out how.

    #1 = gv_curpage. "show current page number
CALL METHOD OF gv_selection 'TypeText'
    EXPORTING
    #1 = ' of '.
CLEAR gv_endpage.
CALL METHOD OF gv_selection 'Information' = gv_endpage
    EXPORTING
    #1 = 4. "get total page number
CALL METHOD OF gv_selection 'TypeText'
    EXPORTING
    #1 = gv_endpage. " show total page number
