Get Record count and text of PreparedStatement

Hi,
Is it possible to get a count of the records returned in a ResultSet?
Also, is it possible to get the text of a query(PreparedStatement). I am using a PreparedStatement, and want to know what the actual query looks like, with the parameters. i.e. Are the parameters being set correctly or not.
Thanks,
Dewang

Is it possible to get a count of the records returned
in a ResultSet?You will have to count them - I don't know of any other way.
I am using a
PreparedStatement, and want to know what the actual
query looks like, with the parameters. i.e. Are the
parameters being set correctly or not.You will have to use debugging statements (possibly on both sides - in the Java and in your stored procedures if you are using them). You have to assume that your JDBC driver is managing the conversions properly, as long as you match the data types right. It's really pretty straight-forward, just a little tedious.

How can I get record count with a query?

In Client/Server pplication,the client send a query to server.
How can server get record count by oracle call interface?
Is it need execute "select count(*) from ...."?

Yes.
Either that or increment a counter for each record fetched and
loop round until you hit the last record.
The first method would be more efficient on large datasets.

Maximum record counts and property counts

Hello,
I am looking for the document/link that mentions maximum record counts and maximum property counts for each record.
let say there are 1.5million records and each record has 2000 properties. Not sure if it can be handled nicely.
Mdex version is 6.2.1 at this point. but can upgrade if higher version can handle more.
Thanks,

Jeremy is pretty much correct. There are no limitations except by performance.
Start with the Performance Tuning Guide - here is a link to the 6.4.1 document:
http://docs.oracle.com/cd/E41223_01/Mdex.641/pdf/PerfTuningGuide.pdf
For your questions, start with Chapter 5 and read how properties/dimensions affect performance and this will help drive how you architect your queries and pipeline configuration/index setup to be most efficient.

How can i get records of all text messages

How do you get records of all your texts? Everyone tells me to go to text usage for my number but it does not show up. Any ideas? I need them like now

Hey there Amanda_x,
I've heard your cry for help and I am here to assist. Are you looking just for the numbers that you've texted and received texts from? Or are you looking for the actual text message conversation?
If you are just looking for the numbers that you've texted and received texts from you can retreive that information through My Verizon. Once you are signed in as the account owner you would click on "view my usage" under Manage My Account. From there you can click on Breakdown of Recent Activity and from there you can view the messaging log for your line.
If you are looking for previous text messages that may have been deleted. That cannot be retreived through My Verizon.
Verizon Wireless is only able to provide an average of the last 3-5 days of content, but never more than ten days from the date and time the message is delivered. Only messages that are received may be available. We also must receive a message with your consent and have it notarized and submitted by an attorney or law enforcement official. You can have those documents faxed to (847) 706-7276.
Let me know if you have any additional questions.

Get records count of all tables

Hi ,
I am trying to get the record count of all tables using dynamic query. I don't know how to put the value in placeholder. I tried the below code.
SET SERVEROUTPUT ON SIZE 1000000
DECLARE
     CURSOR table_list
     IS
     select OBJECT_NAME from user_objects
     where object_type in ('TABLE')
     and object_name not like '%AUDIT_DDL%'
     AND object_name not like 'MD_%'
     AND object_name not like 'EXT_%'
     AND object_name not like 'STG_%'
     AND object_name not like 'SYS_%'
     AND object_name not like 'TMP_%'
     AND object_name not like 'TEMP_%'
     order by 1;
     v_count     NUMBER :=0;
     query_str VARCHAR2(1000);
BEGIN
     FOR table_name IN table_list
     LOOP
          query_str :='SELECT COUNT(1) FROM ' || table_name.OBJECT_NAME;
dbms_output.put_line(query_str);
          dbms_output.put_line('Table Name:' || table_name.OBJECT_NAME );
          v_count:= execute immediate query_str;
          dbms_output.put_line('Table Name:' || table_name.OBJECT_NAME || ', Count ' || v_count );
     END LOOP;
END;
I know I am doing wrong in the bold lines. But not sure how to fix it. Please help. Thanks in advance.

Hi,
Welcome to the forum!
What you posted is basically right, assuming you really want to do dynamic SQL t all.
The only problem with
961618 wrote:
          query_str :='SELECT COUNT(1) FROM ' || table_name.OBJECT_NAME; would be if the object name included special characters (such as single-quotes) or lower-case letters. To avoid any possible problems, I would put the object name inside double-quotes:
...     query_str := 'SELECT COUNT (*) FROM "' || table_name.OBJECT_NAME
                                           || '"';
          v_count:= execute immediate query_str;
The correct syntax is
execute immediate query_str INTO v_count;V_count will be the number of rows in a single table. Keep another variable (say total_v_count) that keeps the total count so far.
Do you really need dynamic SQL?
SELECT     SUM (num_rows)     AS total_rows
FROM     user_tables
WHERE     table_name     NOT_LIKE '%AUDIT_DDL%
AND     ...
;gets the same information, accurate as of the last time statistics were gathered, and some of the numbers may be approximate. Depending on how you use the results, that may be good enough for you. If you actually have 10,000,123 rows, and the query says you have 10,000,000, does it really matter?

How to get back counts and ratings

I just went to restart iTunes to find it's not there. I had to reinstall FF earlier and it removed iTunes as well.
How can i get my play counts and ratings back as I have nearly 4 years of plays and ratings.
I still have the XML file andother in a seperate folder.

+iTunes Library (which is labelled as database file).+
This is the ITL file. Windows must not be set to display file extensions,is why you aren't seeing it.
+There is also a lot of iT temp files.+
This is a big clue that something is interfering with itunes savings its ITL file. Which you can look into later.
For now, to get your database back,
1. Display file extensions in Windows
2. Close itunes
3. Rename your current ITL file to something like "iTunes Library Is blank.ITL"
On XP, the default path is C:\My Documents\My Music\iTunes
4. copy that saved ITL file to the C:\My Documents\My Music\iTunes
(assuming you are using the default path as I posted before)
5. Open itunes. Everything should be there, up to the date you made the backup to that other folder

File to Jdbc: how to get record count from DB table

Hello,
i have a scenario file to JDBC....ihave to insert input file data to DB table.
now my requirement is ..if i insert a file with 50 records to db table on first time, and then next time if i insert the file with 100 records to db table....the count should start from 51 in db table.
if i insert another file 3rd time, with 25 records, the count shold start from 151...so how can i achieve this functionality....
i think following options:
1. in mapping write lookup to call JDBC sender channel and fetch count and map same to target filed of DB. if this is ok...please provide UDF code..2. db triggers (not suitable for my req.)
So kindly let meknow possible solutions and required UDF codes..please
Thanks in advance...SARAN

>>>..if i insert a file with 50 records to db table on first time, and then next time if i insert the file with 100 records to db table....the count should start from 51 in db table.

i think following options:
Suggestions:
1)Create an id column in db table. Talk to DB guy to create oracle sequencer for that column. So, every time you insert record that field will be updated with oracle sequencer. You dont need to handle this.
Refer this link
http://www.techonthenet.com/oracle/sequences.php
2) If you want to handle via pi, following suggestions..
If you use PI 7.1 or above, use jdbc lookup in the mapping and do the query something like this
Refer this link
/people/jin.shin/blog/2008/02/15/sap-pi-71-mapping-enhancements-series-graphical-support-for-jdbc-and-rfc-lookups
Do select query as below
select count(*) from tablename;
the above query will return number of rows exist in the table. So use that value and map it in the target field.
If you use pi 7.0 or below then use the previous reply and do the UDF implementation for jdbc lookup during mapping. Because jdbc lookup does not support in those versions.
Hope that helps.

Recording 'partners' and 'texts' in VA01 Tcode

Hi,
while recording VA01 tcode i'm not able to record partners and also texts.
can any one tell me how to record the partners and texts in VA01.
Thanks & Regards,
Prasad.

Prasad,
In regards to Text, you can save text using FM 'SAVE_TEXT' provided you know the ID and OBJECT. For Sales Order Header text usually the OBJECT is 'VBBK' and the NUMBER is '<SO Number>'. For Sales Order Item text usually the OBJECT is 'VBBP' and the NUMBER is '<SO Number><Item Number>'. You will have to find out the ID of the Text from its attributes.
Thanks

I created an Execute SQL Task in ssis package to get the counts and store it in the variable and I use the variable in the control flow

How to get record created and modified user name from SharePoint Database?

Hi,
My SharePoint Portal is in Window Authentication. Some users have added requests to Lists. I want to find user name of the Created By and Modified By.
Only ID is available in the corresponding columns in Content Database table. In which table the users details would store in Content Database.
Thanks & Regards
Poomani Sankaran

hi, you can find the user details inside UserInfo Table in content database. But i would suggest not to directly query the content databse not even for select as it will affect the indexes.
why not follow the link
http://www.sharepoint4arabs.com/AymanElHattab/Lists/Posts/Post.aspx?ID=99
also if you just need the basic created by and modified by info than use SharePoint Object Model To get these values using ECMA script use below link

How to get record count value in variable

Hi,
i wanted to capture record count value in the variable?
Please let me know how to do this?
Thanks,
jag

To determine count of records, use: count(field_name) -- replace field_name with your appropriate field.
You don't have to save the record count value in a variable. You can directly use the condition <?if: count(field_name) > 0?> display table <?end if?>
If you want to store it in a variable: use <?variable:record_cnt;count(field_name)?>
Take a look at this post that uses a record count: https://blogs.oracle.com/xmlpublisher/entry/no_data_found

Getting Record Count From Date Range - IDE: PLSQL Developer

I would like to count the number of member records that fall within a specified date range based on the members effective and expiration dates and their 'elg_code'. I have posted the SQL for some sample data. What I would like to see returned is three columns of counts where the members eff_date exp_date fall within the date range specified by the SQL and have an Elg_code of ' ' (one blank space).
So, what I would like is all members with elg_code ' ' where there eff_dt and exp_dt range falls within APR 2012, MAY 2012 & JUN 2012. So, based on the sample data I posted, Mark, where his elg_code record is ' ', his eff_dt is 1/1/2011 and his exp_dt is within APR 2012 (4/30/2012). Mark's range falls within APR 2012, but not MAY or JUNE of 2012. Marty would tally for both APR and MAY since his eff_dt is before MAY 2012 and his exp is within MAY 2012. etc..
Based on the data below, the results should look like:
APR MAY JUN
4 3 2
APR should have FRANK, MARK, MARTY, MARY,
MAY should have FRANK, MARTY, MARY
JUN should have FRANK and MARY
NOAM and JEAN should not show up as their records with elg_code ' ' do not have eff_dt and exp_dt records that fall within APR-JUN 2012.
So what I tried without success as it appears I have some kind of Cartesian issue (?), is:
select count(m1.mbr_name) APR,
count(m2.mbr_name) MAY,
count(m3.mbr_name) JUN
from mbr2 m1,
mbr2 m2,
mbr2 m3
where m1.eff_dt < '01-may-2012'
and m1.exp_dt > '01-apr-2012'
and m1.elg_code = ' '
and m2.eff_dt < '01-jun-2012'
and m2.exp_dt > '01-may-2012'
and m2.elg_code = ' '
and m3.eff_dt < '01-jul-2012'
and m3.exp_dt > '01-jun-2012'
and m3.elg_code = ' '
Below is the DML
Thanks for any assistance!
create table mbr2 (mbr_name varchar(10), grpid varchar(1), eff_dt date, exp_dt date, elg_code varchar(1))

Hi,
Here's one way:
WITH all_months AS
 SELECT LEVEL AS month_num
 , ADD_MONTHS (first_month, LEVEL - 1) AS month_begin
 , ADD_MONTHS (first_month, LEVEL) AS next_month_begin
 FROM (
 SELECT TO_DATE ('04-01-2012', 'MM-DD-YYYY') AS first_month
 , TO_DATE ('06-01-2012', 'MM-DD-YYYY') AS last_month
 FROM dual
 CONNECT BY level <= 1 + MONTHS_BETWEEN (last_month, first_month)
SELECT COUNT (CASE WHEN month_num = 1 THEN 1 END) AS month_1
, COUNT (CASE WHEN month_num = 2 THEN 1 END) AS month_2
, COUNT (CASE WHEN month_num = 3 THEN 1 END) AS month_3
FROM all_months a
JOIN mbr2 m ON a.month_begin <= m.exp_dt
 AND a.next_month_begin > m.eff_dt
WHERE m.elg_code = ' '
;This assumes you know how many months will be in the output. If you want to derive that from the data, or to give the columns meaningful aliases (such as APR-2011 instead of MONTH_1), then you'll need dynamic SQL (to get separate columns for each month) or string aggregation (if you don't mind one big VARCHAR2 column, formatted to look like several columns). See {message:id=3527823}
If you don't mind modifying the query a little every time you run it, you can hard-code the number of columns and the month names. In the main query, put exactly as many lines as you need, with the alias you want at the end. That is, instead of
, COUNT (CASE WHEN month_num = 2 THEN 1 END) AS month_2say
, COUNT (CASE WHEN month_num = 2 THEN 1 END) AS may_2012I'm not sure exactly what the problem was with the query you posted. It looks like this site cut off parts of the query.
One thing that is definitely a mistake is that you're comparing DATE columns to VARCHAR2 literals. Never compare a DATE to a VARCHAR2; compare DATEs to DATEs (or compare VARCHAR2s to VARCHAR2s). So instead of
and m1.exp_dt > '01-apr-2012'you should say
and m1.exp_dt > TO_DATE ('01-apr-2012', 'dd-mon-yyyy')Thanks for posting the CREATE TABLE and INSERT statements; that's very helpful.

Getting Sum, Count and Distinct Count of a file

Hi all this is a UNIX question.
I have a large flat file with millions of records.
col1|col2|col3
1|a|b
2|c|d
3|e|f
3|g|h
footer****
I am supposed to calculate the sum of col1 =9, count of col1 =4, and distinct count of col1 =c3
I would like it if you avoid external commands like AWK. Also, can we do the same by creating a function?
Please bear in mind that the file is huge
Thanks in advance

This sounds like homework for a shell class, but here goes. Save into a file, maybe "doit". Run it like this:
$ ./doit < data
<snip>
#!/bin/sh
got0=0
got1=0
got2=0
got3=0
got4=0
got5=0
got6=0
got7=0
got8=0
got9=0
sum=0
cnt=0
IFS='|'
while read c1 c2 c3 junk; do
# Sum and count
echo "c1=${c1}"
case "${c1}" in
[0-9] )
 sum=$(expr ${sum} + ${c1})
 cnt=$(expr ${cnt} + 1)
esac
# Distinct
case "${c1}" in
0 ) got0=1;;

Problem in Getting Child Count And Child Reference of a Group [CS3/WIN]

Hi All, I have Created a group For Some pageItems using kGroupCmdBoss InterfacePtr<ICommand>groupItemsCmd(CmdUtils::CreateCommand(kGroupCmdBoss)); InterfacePtr<IGroupCmdData> groupCmdData ( groupItemsCmd, UseDefaultIID()); UIDList*list=new UIDList(grpList);//grplist contains UID of all items to be grouped groupCmdData->Set(list); ErrorCode status = CmdUtils::ProcessCommand(groupItemsCmd); Till here every thing is working fine. But when i want to traverse through all group item using IHierarchy every time its giving child count as one. InterfacePtr<IHierarchy> child( groupRef, UseDefaultIID() ); int32 grpchildCount = child->GetChildCount(); //always 1 I am not getting why its always return child count as 1. But the same code is working fine when i am creating group using click on Group In UI. Can any one tell me How Top Iterate through group in above case.??? I think when i am executing Group command some document hierarchy is changing becoz of that i am getting issue?? any idea??

Hi Dirk, Thanks For your Reply. ya you are correct I'd call that variable groupHier rather than "child". ---You've omitted the interesting part, how and when you obtain that groupRef. When i am creating group as mentioned above after executing group command i am using. ErrorCode status = CmdUtils::ProcessCommand(groupItemsCmd); b UIDRef grpRef((groupItemsCmd->GetItemList())->GetRef(0)); I am using this reference to set script label("Group") for that group.till here its working fine group is created and script label is set. Then i am iterating through all page items using UIDList itemsOnPage(database); const bool16 bIncludePage = kFalse; const bool16 bIncludePasteboard = kFalse; spread->GetItemsOnPage(pageIndex, &itemsOnPage, bIncludePage, bIncludePasteboard); int noOfItems=itemsOnPage.Length(); for(int32 pageItemIndex=0;pageItemIndex<noOfItems;pageItemIndex++) { UIDRef pageItemRef=itemsOnPage.GetRef(pageItemIndex); //here i am reading script label if (Utils<IPageItemTypeUtils>()->IsGroup(pageItemRef) == kTrue) { InterfacePtr<IScript>script(pageItemRef, UseDefaultIID()); PMString grpScriptLabel=script->GetTag(); if((grpScriptLabel.Compare(kFalse,"Group"))==0) //comparing with group label to check that this is group { // so it is group InterfacePtr<IHierarchy> grpHier( pageItemRef, UseDefaultIID() ); b ASSERT(::GetClass(grpHier)==kGroupItemBoss); //No Asserts here int32 grpchildCount = grpHier->GetChildCount(); // here i am getting always one } } } I check for Ur suggested Assert But i am not getting any assert. And One more interesting thing i found that the group i have created programatically is behaving fine as group in Indesign UI.But when I want To Ungroup In UI by right on Group item And Click UNGRoup option in menu nothing seems to happen. I am really puzzled.
