How to get the number of bytes stored in a field?

Hi Guys,
How can i get the number of bytes stored in a field.
I tried using DESCRIBE FIELD, But here i am getting the length from the definition.
i.e 8 bytes for string and for character value is from definition.
Prompt replies will be Awarded with full points:-)
Thanks,
vinod.

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.

How to get the number of bytes at ethernt port using tcp/ip?

I have data with variable sizes.I am getting the data from another sytem using software C.
How can I get the exact number of bytes coming at the port before using the read command so that the no. of bytes at port has to be given as the input to the tcp read vi?

So may responses saying your question is wrong..... typical of this site, and no decent answer after 5 years !
The answer I have used is to use a call library function:
short int ioctlsocket(unsigned long socket, unsigned long fionread, unsigned long *len);
where fionread is a windows defined constant = 4004667F
The socket can be obtained from using the TCP Get RAW NET OBJECT.vi which comes with Labview (even as far back as version 7).
Good luck.
A protocol requiring such a hack is IMHO very poorly designed. You should always have some way on the wire to determine the data stream size. If the data is fixed size that would be inherent to the protocol, if it's variable sized there should be a fixed size header or a known message termination indication that can be used to determine how to read the rest of the message.
As a side node, I do consider the existence of VISA Bytes at Serial Port a big error, and that is most likely where this question originally came from. Use of "bytes at port" to decode a protocol will ALWAYS lead to protocol errors sooner or later, and code that is unneccessarily complicated to force the routine to deal with the asynchonous reading of the "bytes at port" into the protocol decoding.
If a protocol can't be decoded with fixed size reads, fixed size reads with following variable size reads determined from information in the header, or a specific message termination indication, then it is very badly flawed.

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 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 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 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/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.value: 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 can I get the number of distinct records that each field of a DB table has?

Hi everyone,
I would like to know how to get he number of distinct records that each field of a DB table has. When tracing a SQL statement either in ST12 or ST05, in the plan execution, if the sentence made useage of an index, then I can click in the index name and see this kind of information (no. of distinct values for each field of that index).
Can I do something like this but with the whole fields of a table?
What I have found until now is in Tx ST10; I search for whatever kind of table statistics and then use the function of "Analyze table" (which takes me to Tx DB05). In here, I can enter a table and up to 5 fields in order to get the information that I want.
Is there any other way to do this?

David Reza

Hi David,
You can export the same to excel and sort as per requirement.

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

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 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 string's byte length?

I have some string,I want to get the string's byte length,how
can do it?

I want to get the byte length is 14, how can i get it?
Thanks.

Oh, sorry, whatever the term is (I'm crap with jargon). The
value returned
by asc() for those chars was only two bytes (ie: four hex
digits). I
didn't realise there was more to it than that, and that
2-byte value maps
to some other THREE byte value. I need to do some reading...
> that's what both cf & java counted as the length.
CHARACTER length, sure. No-one's disputing that. On the other
hand,
no-one's asking about it, either.

[groan]
Yes, that's a reasonable strawman there. I was only putting
it in a file
so I could save it and check the number of bytes occupied by
the data.
Clearly... CLEARLY... the OP is not asking for a character
length of that
string. They've said as much.
I copy and pasted the string from their post, and used it as
a
demonstration of how "nine" is not the right answer for the
BYTE LENGTH of
that string. Whether or not the original string was UTF-8,
UTF-16 or
special-marmoset-encoding, it almost certainly was NOT in a
fictitious kind
encoding in which each of those particular characters only
occupied one
byte each, which would mean that "nine" is the correct answer
to the
question.
When I copied those characters from either the web browser
for from my
text-based news agent, notepad identified them (and rendered
them
correctly) as UTF-8, so I'm fairly confident they ARE UTF-8.
Of course
this could be down to some intermediary encoding (pasting
them in to the
original posting, for example, via some encoding-transforming
mechanism),
but Occam's Razor suggests the original question was from a
UTF-8 POV.
But maybe we should quit speculating and ask the OP. Unless
they've
buggered off in despair of how drawn out all this is getting.
For which I
would not blame them.

How to get the number of days in a month?

hi all
is there any way to get the number of days in a given month with a given year? for instance, if year is 2004 and the month is July or February, how can i get the number of days? thanks.

Gee, I don't know ... Maybe this:
Calendar cal = Calendar.newInstance();
cal.set(Calendar.YEAR, 2004);
cal.set(Calendar.MONTH, Calendar.FEBUARY);
System.out.println("max days in month: " + cal.getActualMaximum(Calendar.DAY_OF_MONTH));
Do you not bother reading what people have already posted? Read the API docs on the Calendar class.
