Select by rand()
I have connected my database from java, I am using mysql. I am able to retrieve images from database , but when I try and do it by random it gives me syntax error.
Here is the part of the java code
String cmd ="SELECT * FROM image _ORDER BY rand() LIMIT 6000_ " +
"JOIN tag_value tv ON tv.image_id = image.id " +
"WHERE (tv.tag_id = 1 AND "+ red_colorVal + " BETWEEN tv.STARTVAL and tv.ENDVAL) OR " +
"(tv.tag_id = 2 AND " + orange_colorVal + " BETWEEN tv.STARTVAL and tv.ENDVAL) OR "+
"(tv.tag_id = 3 AND " + yellow_colorVal + " BETWEEN tv.STARTVAL and tv.ENDVAL) OR " +
"(tv.tag_id = 4 AND " + green_colorval + "BETWEEN tv.STARTVAL and tv.ENDVAL) OR" +
"(tv.tag_id = 5 AND " + baby_blue_colorval + "BETWEEN tv.STARTVAL and tv.ENDVAL) OR" +
"(tv.tag_id = 6 AND " + dark_blue_colorval + "BETWEEN tv.STARTVAL and tv.ENDVAL) OR" +
"(tv.tag_id = 7 AND " + pink_colorval + "BETWEEN tv.STARTVAL and tv.ENDVAL) OR" +
"(tv.tag_id = 8 AND " + dark_red_colorval + "BETWEEN tv.STARTVAL and tv.ENDVAL)";
If I remove underlined part its working fine but when I add it its giving me an error.
Here is the error
1064You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'JOIN tag_value tv ON tv.image_id = image.id WHERE (tv.tag_id = 1 AND 0.0 BETWEEN' at line 1
What I am trying to do is that I have 8 sliders on front end part and between slider start val and endval specific images appear ,instead of that I want it to be selected randomly.
Thank you,
no,
see the output in mysql
mysql> select * from image order by rand() limit 8;
-----------------------+
| id | name | X | Y |

| 7 | NB1.jpg | 797 | 583 |
-----------------------+
8 rows in set (0.00 sec)
it gives me the random tables, but in java as I have mentioned in that code it gives me syntax error, I am using the exact syntax as that of this query one.
Thanks,

Weekly Aggregation based on everyday date
Hi All,
i have a table with 3 columns. Id , MeasureDate,Measure. Here Id +MeasureDate as primary key. In this table i want add a column Avg. if i am running today 2/12/2014,2/5/2014,01/29/2014 and so on avarage value will be replaced in the
Avg column .
Give some ideas.
ThiruSeems you need Running Averages. This sample code will help you understand.
CREATE TABLE #RunAVGTestData(ID INT PRIMARY KEY, VALUE INT)
INSERT #RunAVGTestData
SELECT 1,RAND()*10 UNION
SELECT 2,RAND()*10 UNION
SELECT 3,RAND()*10 UNION
SELECT 4,RAND()*10 UNION
SELECT 5,RAND()*10 UNION
SELECT 6,RAND()*10
SELECT a.id, a.value, (SELECT AVG(b.value)
FROM #RunAVGTestData b
WHERE b.id <= a.id)
FROM #RunAVGTestData a
ORDER BY a.id;

Is there a way to make a smart playlist to display albums with NO cover art
I want to see which of my songs do not yet have album art, in an easy manner ... Thanks!!
You can download and run this VBScript (or copy and paste from below). It will create a playlist called "No Artwork" containing all the tracks with no artwork.
The forum TOS requires me to say: "I may receive some form of compensation, financial or otherwise, from my recommendation or link" because I have a paypal donation link on my webpage, but the program is free (donation totally optional)

Imprumut = loan
I have 6 tables:
I have one combobox(from where I select utilizatori(users)) and 2 CheckedListBox(Between first box and second box I have 2 buttons:imprumuta(loan) and restituie(return))
This c# code works just for first user: Utilizator, but something's not good. When I add new utilizator(user) and select it, the loan will be add in my SQL DataBase, but... the book who I selected doesn't move to the right in CheckedListBox and the reason
is that I can't make an return

I nearly made a comment about how the plan doesn't show Bloom filter pruning either - and then I realised why not. The plan you've shown us comes from Explain Plan with literal values present; the trace file shows bind variables with names that are generated when cursor_sharing is set to force or similar - so the run-time plan and the plan from explain plan are almost guaranteed to be different.
Oracle support will need you to supply the plan you get from trying to run the query and then making a call to dbms_xplan.display_cursor() - dbms_xplan in 10g | Oracle Scratchpad If you do this I think you'll find that the pstart/pstop columns contain entries like :BF0000, and you may even find operations link PX JOIN FILTER CREATE / PX JOIN FILTER USE
A couple of generic notes:
if a query does sufficient work to merit parallel execution, then it's usually better to supply the best possible information to the optimizer, which means using literals rather than bind variables - you could try executing the query with the hint /*+ cursor_sharing_exact */ to stop Oracle from turning your literals into binds; it might be the presence of bind variables that's making the optimizer choose a path that has to include bloom filter pruning in your case.
Where you have the to_date() call you've used a four-digit year - which is a very good thing and helps the optimizer - but it's also a good idea to include an explicit format string as well: with a four-digit year this probably won't make any difference, but it avoids any risk of ambiguity for the optimizer.
I made a comment about the P->S stage and bottlenecks - I spent a couple more minutes looking at the plan, and I see the optimizer has used concatentation: in effect it has run three query blocks one after the other and fed the results to the query co-ordinator - in this case the P->S would make no difference to the end-user response time there's always a final P->S to the coordinator, you just happen to have three of them.

Selecting random values from an array based on a condition
Hi All,
I have a small glitch here. hope you guys can help me out.
I have an evenly spaced integer array as X[ ] = {1,2,3, ....150}. and I need to create a new array which selects 5 random values from X [ ] , but with a condition that these random values should have a difference of atleast 25 between them.
for example res [ ] = {2,60,37,110,130}
res [ ] = {10,40,109,132,75}
I have been thinking of looping thru the X [ ], and selecting randomly but things look tricky once I sit down to write an algorithm to do it.
Can anyone think of an approach to do this, any help will be greatly appreciated ...For your interest, here is my attempt.
import java.util.Random;
public class TestDemo {
public static void main(String[] args) throws Exception {
for (int n = 0; n < 10; n++) {
System.out.println(toString(getValues(5, 25, 150)));
private final static Random RAND = new Random();
public static int[] getValues(int num, int spread, int max) {
if (num * spread >= max) {
throw new IllegalArgumentException("Cannot produce " + num + " spread " + spread + " less than or equals to " + max);
int[] nums = new int[num];
int max2 = max - (num - 1) * spread - 1;
// generate random offsets totally less than max2
for (int j = 0; j < num; j++) {
int next = RAND.nextInt(max2);
// favour smaller numbers.
if (max2 > spread/2)
next = RAND.nextInt(next+1);
nums[j] = next;
max2 -= next;
// shuffle the offsets.
for (int j = num; j > 1; j--) {
swap(nums, j - 1, RAND.nextInt(j));
// add the spread of 25 each.
for (int j = 1; j < num; j++) {
nums[j] += nums[j-1] + spread;
return nums;
private static void swap(int[] arr, int i, int j) {
int tmp = arr;
arr[i] = arr[j];
arr[j] = tmp;
public static String toString(int[] nums) {
StringBuffer sb = new StringBuffer(nums.length * 4);
sb.append("[ ");
for (int j = 0; j < nums.length; j++) {
if (j > 0) {
sb.append(", ");
sb.append(nums[j]);
sb.append(" ]");
return sb.toString(); -
RAND() function in OBIEE not working.
Hi Experts,
I am not sure if any of you faced this issue on RAND() funtion in OBIEE. Please refer the below sample query.
select count(ROW_ID) from TABLE1 ------------ +1000+
Select count(ROW_ID) from TABLE1 where RAND() < 0.25 ------- +250+
select Count(ROW_ID) from (Select ROW_ID from TABLE1 except (Select ROW_ID from TABLE1 where RAND() < 0.25)) ------- +750+
Select count(ROW_ID) from (Select count(ROW_ID) from TABLE1 except (Select count(ROW_ID) from TABLE1 where RAND() < 0.25)) where RAND() <0.5 ------- +500+ instead of 750/2 = 375.
The last statement should return the count around 375, but it always return count around 500.
This RAND() funtion is coming only in the logical query, i dont see its being added into the physical SQL Query generated which makes it more difficult to understand how its getting executed.
Any help on this is much appriciated.
Thanks
KrishnaHi Experts,
Any help on this??? -
Hello All,
first of all, I hope that my English will be understandable.
Description:
I must create a report for sales orders by planned deliver date. Most of info what I need are in VBAP, but there is no delivery date there, only in VBAK. I download VBAK by VDATU, result is a list with 500-3k pcs of orders. Next step shouId be I take these order numbers and "insert" them into VBAP-VBELN, but I'm not able to find out how can I do it in VBA (multiple selection, therefore I download that by ERDAT (large interval, because the orders can arrive to system more weeks before delivery date). Result is a code what is downloading VBAP ~ten minutes... It is not acceptable. I would like to choose a simplier example (where problem is the same): MARA.
I have only 2-300 article number per list but I have to download 80k articles because I can filter only prefix and H% is not so exact filter...
One-dimensional array is the only one solution what I tried for that but RFC call is false in that case.
Sub MARA() '(user As String, password As String)
Const TABLA As String = "MARA"
Const UZI1 As String = "there is no connection to R/3"
Const UZI2 As String = "something wrong"
Const CLIENT As String = "300"
Const LANGUAGE As String = "your logon language"
Const SYSTEM As String = "your system"
Const user As String = "your username"
Const password As String = "your pw"

Selecting from partition is taking too much time
The SEARCH_MEMBE_PROVIDER_ROLLUP is partitioned with range-list partition
ROLLUP_ID --range (about 30 partitions ) and other column with list subpartitioned (about 48)
*indexes on columns
b-tree global index on ROLLUP_ID
bitmap local index on ROLLUP_ID, MEMBERONE_ID_1010
bitmap local index on MEMBERONE_ID_1010*
I could not figured it out as some partition's data is coming fast and some partition's data is not coming at all(taking 18 minutes)
any help would be greatly appreciated and please let me know if need more information

SQL> spool offthanks againHi
1) there are two major differences between the plans: serial vs parallel and NESTED LOOPS SEMI vs HASH JOIN SEMI
2) NESTED LOOPS look like a bad choice here, and it also looks like the optimizer badly underestimates it's real cost. Which is a bit odd, because it knows that the outer rowsource has 2701K, i.e. the inner operation would have to be executed 2701K times. Looks like an optimizer glitch, which brings us to the point that Dan has already raised here: you shouldn't be running on an old unsupported version
3) regarding serial vs parallel: it could be due to difference in session settings (ALTER SESSION ENABLE/DISABLE PARALLEL QUERY)
4) the two plans have different values of the filter against rollup_id (7 vs 11), so one possible reason for different behavior is the histogram on SEARCH_MEMBE_PROVIDER_ROLLUP.rollup_id. If you can reproduce the issue on a test database, re-gather stats on this table without histograms (method_opt=>'for all columns size 1', no_invalidate=>false) and see if the problem goes away

Can a script randomly select an action within a specific set for use on multiple images?
Hi there.
I have a folder of 200+ similar images (taken in a photobooth).
I have made 8 seperate actions within the same set that apply slightly different textures to a image. Actions are titled 1, 2, 3 ...etc.
I am wanting a way to get all the images to have one of the actions (randomly selected) applied to them.
I'm pretty confident that this could be achieved with scripting, but have no idea how to write one.
If the images were sequecnially applied to action 1 then 2 then 3 and so on (repeating when back to 8) this would also be suitable.
I am fairly new to scripting so please keep answers simple where possible,
Many thanks.
Wil StevensSomething like this?
// make variable to hold the name of the action set
var actionSet = "myActionSet";
// make variable to hold an array of action names you want to use from that set
var actionArray = ["Action 1","Action 2","Action 3","Action 4","Action 5","Action 6","Action 7","Action 8"];
// either hard code the folder path
// var sourceFolder = new Folder('~/desktop/booth');
// or prompt for folder
var sourceFolder = Folder.selectDialog("Select the booth pix folder");
// if prompting user make sure they didn't cancel the dialog without selecting a folder
if(sourceFolder != null ) {
// make variable for processed folder
var processedFolder = new Folder(sourceFolder+'/processed');
// make sure it exists
if(!processedFolder.exists) processedFolder.create();
// get the files from the folder using a mask to only get certain file extensions
var files = sourceFolder.getFiles(/\.jpg$/i);// here we are only getting jpeg files with .jpg or .JPG extension
// now loop through the files and apply random action
for(var f=0;f<files.length;f++){
// open a file in the files array
var currentDoc = app.open(files[f]);
// generate a random number between 0 and 7 ( array index is zero based )
var rand = Math.floor((8)*Math.random());
// apply a random action to the opened document
app.doAction(actionArray[rand], actionSet );
// make variable for the new file path
var saveFile = new File(processedFolder+'/'+files[f].name);
// save the file
SaveAsJPEG( saveFile, 8, true );
// close the doc
currentDoc.close(SaveOptions.DONOTSAVECHANGES);
// done with this file so loop to next
}// end of loop
// done with all the files in the files array
alert('Done');
}// end of if valid folder

How to use Rand() (ANSI Function)as such in Oracle
I need to use Rand() function as such in ANSI format in oracle how to use it.
I don't want to use the available DBMS_RANDOM.RANDOM(), i want to use ANSI Function as such in Oracle
Please help meI don't want to use the available DBMS_RANDOM.RANDOM()Whats wrong with dbms_andom?
In any case you can simply write a function wrapper to have same functionality as rand():
SQL> create or replace function rand (max_val int default 32767)
return int
as
begin
return dbms_random.value (0, max_val);
end rand;
Function created.
SQL> select rand(50) from dual

How to randomly select data from excel using labview.
A very good day to all. I am actually working on a system that will be selecting integer number from randomly generated set of number. If that wouldnt be possible, I would like the system to be able to select number from the set of numbers which have already been randomly generated from excel. kindly help me with the solution. To make myself clear, supposing I have set of numbers from 1 to 10, I want a labview setup that will be picking these numbers one after the other either with replacement or without from excel or self generated. I know this is possible in matlab but would prefer labview if possible. Thanks
Solved!
Go to Solution.Most, if not all, of the languages I've run across have a rand() function that returns a random number between 0 and 1. Getting some other range is up to the programmer. Usual method is to multiply by the range you need and add an offset to adjust the mean. For instance if you need a random number between 200 and 300 the formula might look like " rand()*100+200 ". If you need an integer, you can use the round function (which will leave it as a float with no decimal pportion) or the conversion (to int). All of this is doable and straightforward in LabVIEW. Have a look: http://digital.ni.com/public.nsf/allkb/FCCDCD678EEF3A9186256D7B008054F5

SELECT of OCILobLocator in Non Blocking mode
Hi all.
I have problem:
I try select BLOB field into OCILobLocator* buffer in Non Blocking mode, and receive 'ORA-03106: fatal two-task communication protocol error' sometimes.
Details:
Application contains two threads : 1. select blob field, 2. update it.
I tried separate update and select to different apps (and run its in one time) - problem reproduced.
problem reproduced for OCIStmtFetch and OCIStmtFetch2.
If disable non blocking mode - problem disappear.
if error appear - record level error code contains 1405. Need wait few minutes for error message appearing (~1 minute in my case).
Using of OCI_DEFAULT in OCIDefineByPos instead OCI_DYNAMIC_FETCH don't solve problem.
I use oracle server and client library with version 10.2.0.4
Output sample:
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #877: 1405
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #54: 1405
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #877: 1405
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #54: 1405
Can anybody help me ?

Edited by: user13011391 on 20.04.2010 6:15Hi all.
I have problem:
I try select BLOB field into OCILobLocator* buffer in Non Blocking mode, and receive 'ORA-03106: fatal two-task communication protocol error' sometimes.
Details:
Application contains two threads : 1. select blob field, 2. update it.
I tried separate update and select to different apps (and run its in one time) - problem reproduced.
problem reproduced for OCIStmtFetch and OCIStmtFetch2.
If disable non blocking mode - problem disappear.
if error appear - record level error code contains 1405. Need wait few minutes for error message appearing (~1 minute in my case).
Using of OCI_DEFAULT in OCIDefineByPos instead OCI_DYNAMIC_FETCH don't solve problem.
I use oracle server and client library with version 10.2.0.4
Output sample:
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #877: 1405
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #54: 1405
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #877: 1405
execute_select(): can't make OCIStmtFetch2: status = -1, message = 'ORA-03106: fatal two-task communication protocol error
', error code = 3106, row errors: #54: 1405
Can anybody help me ?
m.b. exists workaround ?

Select query on table rcv_lots_interface is always returning null
Hi ,
I need a help on the below issue.
The issue is after creating PO in Oracle 11i I receive it in MSCA application.
When we receive it at that point data gets inserted in the table " rcv_transactions_interface " and we have written a trigger on it.
From the trigger on table " rcv_transactions_interface " we are calling a package and in the package we have select query on "rcv_lots_interface."
But the select query is always returning null even though we are passing the correct "interface_transaction_id " and also after the "Receiving Transaction Processor" is executed i can see data in the table " RCV_LOT_TRANSACTIONS " for the same transaction.
Below is the sample code i am using.
CREATE OR REPLACE TRIGGER inv.RCV_TRAN_TRIGGER

v_expiration_date :=NULL;

END;
Need your help to understand why the below query is always returning null and what is the solution for it ?
SELECT rli.lot_num , rli.expiration_date
FROM apps.rcv_lots_interface rli
WHERE rli.interface_transaction_id = p_interface_transaction_id ;

There are a lot of bugs listed in Metalink with respect to wrong results and function-based indexes.
Here are a few:
Bug 4028186 Wrong results if function based index exists
Bug 4717546 Wrong results / poor plan when function based index exists
Bug 5092688 Wrong results if function based index exists
Based on reviewing them the workarounds range from dropping the index to setting "_disable_function_based_index" to TRUE.Facinating. It seems to me that if you use the undocumented intitialization parameter you might just as well drop the FBIs too.
Another hazard of FBIs is the Law of Unintended Consequences. 2 years ago we tried to use one to speed up a query in a PL/SQL package. Worked OK for that purpose, but an unrelated loader on the affected table ran and rand but never finished until the FBI was dropped.
