Searchin pattern in datbase table.(Number of rows in table :More than70Lac)

Actually i have a db table having 2 columns(columnA,time).db table has 70lac rows.I have to retireve all those values which are present min. 2 times in the interval of 10 minutes. eg. columnA,time values are
{a,June-01-2011 10:13:12},{b,June-01-2011 10:14:12},{b,June-01-2011 10:15:12},{c,June-01-2011 10:16:12},{b,June-01-2011 10:17:12},{d,June-01-2011 10:18:12},{d,June-01-2011 10:25:12},{e,June-01-2011 10:26:12},{e,June-01-2011 11:38:12},{f,June-01-2011 10:39:12},{f,June-01-2011 10:43:12},{a,June-01-2011 10:44:12},{f,June-01-2011 10:51:12},{b,June-01-2011 10:51:12},{b,June-01-2011 10:53:12},{c,June-01-2011 10:54:12},{g,June-01-2011 10:55:12},{b,June-01-2011 10:56:12},{b,June-01-2011 10:57:12},{b,June-01-2011 10:58:12}
Then I have to retrieve following rows in output : {b,June-01-2011 10:14:12},{b,June-01-2011 10:15:12},{b,June-01-2011 10:17:12},{d,June-01-2011 10:18:12},{d,June-01-2011 10:25:12},{f,June-01-2011 10:39:12},{f,June-01-2011 10:43:12},{b,June-01-2011 10:51:12},{b,June-01-2011 10:53:12},{b,June-01-2011 10:56:12},{b,June-01-2011 10:57:12},{b,June-01-2011 10:58:12}
Is it related to data Mining? i have 70 lac rows in database table.I have to search such type of many patterns in my application.I have spent hours looking for tutorials on Google. However I cannot seem to find anything that holds the hand? try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic. Can java data mining solve the problem?

Hi,
Sorry but this does not look like a data mining problem at all.
Thanks, Mark

first of all thanks for reply, i will take care of your suggestion.
Number of rows in table : More than 3*10pow7(30 Milion rows)(But it can be more than 120 milion)
Actually i have to display all those rows which setisfy following criteria:( Specific value of column A should appear min 2 times in the interval of 10 minutes.)
for eg.
eg 1. {b,June-01-2011 10:14:12},{b,June-01-2011 10:15:12},{b,June-01-2011 10:17:12}{This set is appearing 3 times in the any interval of 10 minutes.}
EG2 {a,June-01-2011 10:13:12} is present only one time,so i dont want this rows in output.
EG# {e,June-01-2011 10:26:12},{e,June-01-2011 11:38:12} is present 2 times in db,but not in the interval of 10 minutes,so i dont want this rows as output.(t1=10:26:12,t2=11:38:12 difference is more than 10 minutes.)
In my eg. i specified only 2 columns but in actual scenario there will be 8-10 columns in table.This is only one pattern which i specified,but there are many more pattern which i have to search in db.As specified above in eg. was only one pattern,After fulfiling this pattern It has to pass many other pattern.and i want result should be retrieved very fast.
Please dont go into answer of above eg.Actually i want, what should be approach of such type of problems?

Limiting ADF table number of rows is not working

Dear All,
I know this question might seems to be a little bit trivial but I have been going in circles for a long time now and can't figure out where I'm going wrong, I'm using Jdeveloper 11g TP4 and developing an ADF RC application, I have a table that I need to limit the number of rows displayed in this table to X number of records and incase the result is more than X navigation buttons should be displayed, I changed the rows attribute in the af:table tag to say 2 but the table is still being displayed with all the rows, could someone please explain where is the missing piece?

Merging two separate Tables into One - different number of rows

Hi. I have a problem. Oracle 10.2.0.4.0
7 years ago when i was learning how to query my teacher told me that is possible to creata some kind of report where results could be combined in 1 view(report) witch in different variable could have different number of rows.
I just remember that there is needed to use group by function and some join?
Please help
In link there is a sample sample view
I need to combine Table A using D variable with Table B to become Wynik(result)
Tables create
CREATE TABLE "TABELA_A" ( A NUMBER,B NUMBER,C NUMBER,D NUMBER ) ;
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (123, 1, 70, 999)
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (123, 2, 80, 999)
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (234, 1, 100, 111)
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (456, 1, 10, 222)
CREATE TABLE "TABELA_B" ( D NUMBER,E VARCHAR2(255),F NUMBER ) ;
INSERT INTO "TABELA_B" (D, E, F) VALUES (999, 'A', 1);
INSERT INTO "TABELA_B" (D, E, F) VALUES (999, 'B', 1);
INSERT INTO "TABELA_B" (D, E, F) VALUES (999, 'B', 3);
INSERT INTO "TABELA_B" (D, E, F) VALUES (999, 'C', 1);
INSERT INTO "TABELA_B" (D, E, F) VALUES (111, 'A', 1);
INSERT INTO "TABELA_B" (D, E, F) VALUES (111, 'C', 2);
And to become result - in picture

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
- dynamic sampling used for this statement
Statistics
0 recursive calls
0 db block gets

225 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
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

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.

How to restrict number of row/lines in a table in RTF

Hi,
Im working on PO report. It has header information in the header part of RTF. But coming to the lines , I put that under a different group in the table in the body part of the RTF. I did a FOR loop for printing PO Lines because it does have multiple line information. But now i have to restrict the number of rows in that table per page irrespective of number of PO Lines. After printing 20 rows in the table, it should go to the next page. Im going through the other threads for the solution.
Thanks,
venkat

There are so many thread regarding this ,
pls go thru them patiently...
logic is something like....
use if condition and position() and say page-break..
use for-each@section instead of for-each..so that the headed info is maintained with regards to PO lines
happy searching...
if you cant get still, last option send me mail with details

How to add the Row count(number of rows in table) in the table header?

Hi,
I'm having a table. This table is viewed when i click on a search button.
<b>On the table header it should dynamically display the number of rows in the table, i.e., the row count.</b>
How to do this? could any one explain me with the detailed procedure to achieve this.
Thanks & Regards,
Suresh

If you want to show a localized text in the table header, you should use the <b>Message Pool</b> to create a (parameterized) message "tableHeaderText" like "There are table entries".
Next, create a context attribute "tableHeaderText" of type "string" and bind the "text" property of the table header Caption UI element to this attribute.
Whenever the table data has changed (e.g. at the end of the supply function for the table's data source node), update the header text:
int numRows = wdContext.node<TableDataSourceNode>().size();
String text = wdComponentAPI.getTextAccessor().getText
IMessage<ComponentName>.TABLE_HEADER_TEXT,
new Object[] { String.valueOf(numRows) }
wdContext.currentContextElement().setTableHeaderText(text);
Maybe you want to provide a separate message for the case that there are no entries.
Alternatively, you can make the attribute calculated and return the header text in the attribute getter.

and the javascript variable having the current row number is row_number
on submitting it goes to second.jsp page. There i need that row_number value.
Can anyone help me to solve this?

How to control the number of rows selected from a sybase database table?

Hi, JDBC guru,
I'm working on project using Sybase 11.9.x database.We need to process a record in a table,first select it from the table,then do some computing,finally write it to a dbf file, if the above steps succeed,remove the original row in the table.Quite evidently, all these operation should be put into one transaction. But how can I select just a number of rows from the sybase database table?
Any hints?
Thank you in advance.

How to set max. number of rows in a table?

Hi,
I'm working on a SCADA interface. In this application there are different tables with vertical scroll bar.
I prefer to make visible only the initialized rows (I've initialized 40 blank rows of a table with a string array). Since the window not contain all 40 rows but only 20 rows, I set the rows number of "table properties window" to 20; so I added a vertical scroll bar.
Now, when a user scroll the scroll-bar, he can view not only the 40 rows initializated, but an undefined number of rows.
There's a way to visualize only a limited number of rows?
Thanks in advance!

New table without statistics returns invalid number of rows

Hi,
I've been searching for a while now for an explanation for the following "problem"
We have an Oracle 11.1.0.7 database on AIX5.3
In this database we have two tables, called KRT_PRODUCTS_INFO and KRT_STRUCTURES_INFO ( the table name don't really matter ).
The scenario is as following:
If we recreate these tables like:
CREATE TABLE KRT_PRODUCT_INFO_BUP AS SELECT * FROM KRT_PRODUCT_INFO;
DROP TABLE KRT_PRODUCT_INFO CASCADE CONSTRAINTS;
CREATE TABLE KRT_PRODUCT_INFO (...) TABLESPACE PIM_DATA NOLOGGING NOCOMPRESS NOCACHE NOPARALLEL MONITORING;
CREATE INDEX KRT_PRODUCT_INFO_X1 ON KRT_PRODUCT_INFO (PRODUCT_NUMBER) NOLOGGING TABLESPACE PIM_DATA NOPARALLEL;
CREATE INDEX KRT_PRODUCT_INFO_X2 ON KRT_PRODUCT_INFO (PIM_ARTICLEREVISIONID) NOLOGGING TABLESPACE PIM_DATA NOPARALLEL;
INSERT INTO KRT_PRODUCT_INFO (SELECT * FROM KRT_PRODUCT_INFO_BUP);
COMMIT;
CREATE TABLE KRT_STRUCTURE_INFO_BUP AS SELECT * FROM KRT_STRUCTURE_INFO;
DROP TABLE KRT_STRUCTURE_INFO CASCADE CONSTRAINTS;
CREATE TABLE KRT_STRUCTURE_INFO (...) TABLESPACE PIM_DATA NOLOGGING NOCOMPRESS NOCACHE NOPARALLEL MONITORING;
CREATE INDEX KRT_STRUCTURES_X1 ON KRT_STRUCTURE_INFO (STRUCTURE_GRP_REV_ID) NOLOGGING TABLESPACE PIM_DATA NOPARALLEL;
CREATE INDEX KRT_STRUCTURES_X2 ON KRT_STRUCTURE_INFO (STRUCTURE_GRP_IDENTIFIER) NOLOGGING TABLESPACE PIM_DATA NOPARALLEL;
CREATE INDEX KRT_STRUCTURES_X3 ON KRT_STRUCTURE_INFO (STRUCTURE_GRP_ID) NOLOGGING TABLESPACE PIM_DATA NOPARALLEL;
INSERT INTO KRT_STRUCTURE_INFO (SELECT * FROM KRT_STRUCTURE_INFO_BUP);
COMMIT;
and we run a complex query with these two tables, this query only return a couple of rows ( exactly 24 !!! )
If we however generate statistics on these tables after creation, the correct number of rows is returned, being 1.167.991 rows
The statistics are gathered using:
BEGIN
SYS.DBMS_STATS.GATHER_TABLE_STATS (
OwnName => 'PIM_KRG'
,TabName => 'KRT_PRODUCT_INFO'
,Estimate_Percent => NULL
,Method_Opt => 'FOR ALL COLUMNS SIZE REPEAT '
,Degree => NULL
,Cascade => TRUE
,No_Invalidate => FALSE);
END;
BEGIN
SYS.DBMS_STATS.GATHER_TABLE_STATS (
OwnName => 'PIM_KRG'
,TabName => 'KRT_STRUCTURE_INFO'
,Estimate_Percent => NULL
,Method_Opt => 'FOR ALL COLUMNS SIZE REPEAT '
,Degree => NULL
,Cascade => TRUE
,No_Invalidate => FALSE);
END;
/I can imagine that the 'plan' for the query used is wrong because of missing statistics.
But I can't imagine that it would actually return an incorrect number of rows.
I tested this behaviour in Toad and sqlplus ( first thought it was Toad ), and both behave the same.
Another fact is, that the "problem" is NOT reproducable on our TEST environment, that runs on Oracle 11.1.0.7 on Windows2008
Just to be sure this is the "complex" query used. It is not developed by me, and I think it looks somewhat strange but that shouldn't matter:
SELECT sr."Identifier" STRUCTURE_IDENTIFIER
, ar_i."Identifier" ITEM_NUMBER
, SUM (REPLACE (NVL (s.HIDE_LE10, 0) + NVL (p.HIDE_LE10, 0), 2, 1))
hide_le10
, SUM (REPLACE (NVL (s.HIDE_LE30, 0) + NVL (p.HIDE_LE30, 0), 2, 1))
hide_le30
, SUM (REPLACE (NVL (s.HIDE_LE40, 0) + NVL (p.HIDE_LE40, 0), 2, 1))

These two tables are in the PIM_KRG schema while the other tables in the query are distributed across two other schemas "KRAMP_HPM_MAIN" and "KRAMP_HPM_MASTER" ?
Do you happen to have the same table names occurring in multiple schemas - the query is then referencing the data in the wrong schema ?
Hemant K ChitaleHi,
This is not the case. The KRAMP_HPM schema's are application dedicated schema's
And this also then does not explain why the results are correct after generating statistics.
Anyway thanks for the tip.

How to find number of rows in tables

Hi,
Can you please help me how to know the number of rows in all the tables databsae.
Thanks In Advance,

Just found out that the behaviour changed in 11.2.0.2:
SQL> select * from v$version where rownum = 1
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - Production
1 row selected.
SQL> select owner, table_name, column_value cnt
from (select owner, table_name, 'count(ora:view("' || owner || '","' || table_name || '"))' xq
          from all_tables
         where table_name in ('EMP', 'DEPT')),
       xmltable (xq) order by owner, table_name desc
OWNER                          TABLE_NAME                     CNT

XMLIndex: finding indexed XPaths and the number of rows in the path table

Hi,
I am storing non-schema-based binary XMLs in an XMLType column in 11g (11.1.0.6.0) and would like to index the XMLs either partially or fully using XMLIndex. I'm expecting to have a large number (tens of millions) of XML documents and have some concerns about the size of the XMLIndex path table.
In short, I am worried that the path table might grow unmanageable large. In order to avoid this and to plan for table partitioning, I would like to create a report of all indexed XPaths in an XMLIndex and to find out how many times each path is actualized in the path table. I would do this for a representative XML sample.
I have been creating XMLIndexes with different exclude/include paths, gathering stats with DBMS_STATS (estimate_percent = 100) and selecting the number of rows in the path table through USER_TABLES.
If anyone knows a more straightforward way of doing this all advice is very much appreciated.
Best Regards,
Rasko Leinonen

Thanks Marco,
I managed to get out all indexed paths using the following SQL. It took a while to understand how the join the XDB.X$PT39CW6BJR8W4VVE0G0LLGA0OCR5 and XDB.X$QN39CW6BJR8W4VVE0G0LLGA0OCR5 tables together but got there in the end. This helps to clarify which XPaths are being currently indexed by the XMLIndex.
begin
for v_row in (select PATH from XDB.X$PT39CW6BJR8W4VVE0G0LLGA0OCR5)
loop
declare
v_i BINARY_INTEGER := 1;
v_id raw(8);
v_len BINARY_INTEGER := 2;
v_skip BINARY_INTEGER := 1;
begin
while v_i < utl_raw.length(v_row.path) and
v_i + v_len <= utl_raw.length(v_row.path)
loop
v_i := v_i + v_skip;
v_id := utl_raw.substr(v_row.path, v_i, v_len);
--dbms_output.put_line(v_id);
for v_row2 in (select LOCALNAME, flags from XDB.X$QN39CW6BJR8W4VVE0G0LLGA0OCR5
where ID = v_id )
loop
if rawtohex(v_row2.flags) = '01'
then
dbms_output.put('@');
end if;
dbms_output.put(v_row2.localname);
if v_i + v_len < utl_raw.length(v_row.path)
then
dbms_output.put('/');
end if;
end loop;
v_i := v_i + v_len;
end loop;
dbms_output.put_line('');
end;
end loop;
end;
Example output:
