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
FLEET                          EMP                            14
FLEET                          DEPT                           4
MICHAEL                        EMP                            14
MICHAEL                        DEPT                           5

How to count number of rows in table

can I get number of row in table except Count(*) in pl/sql
is there any other way

Also posted and answered here
how to count number of rows in table
count(*) will be the fastest way. It is only slow if the table has a vast number of rows, in which case why do you need to know the tables has 73552436467721 rows and not 73552436467737 rows. It doesn't seem to be much use. Either that or you are counting them a lot, which again seems rather pointless.

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.

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;

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.

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 find number of rows after query

I have a simple query page. On this page I enter query criteria and hit the go button I get the query result. (say it finds one record)
On processFormRequest of the controler of this page after I execute (executing explicitly because I am using some bind variable too) the query I print getFetchedRowCount() and getRowCount() and I get 10 (as the total records according bind variable criteria are 10). Where I am expecting 1 as the result.
and I want to get the value of that row as well.
Can anyone please guide me how I can achieve this?
Thanks

Yes I am using queryBean for search region. I can see both, criteria that I am passing through search region and bind variable in the query.
If I pass the customer name it gives me that customer as a result.
but the counts i get doesn't seem to consider that search criteria from query region.
Interestingly when I execute the query again with the same customer name ...I get the correct count. i.e 1
Followoing is the query from "about this page-->business component reference details."
SELECT * FROM

How to find number of rows inserted by dynamic query

EXECUTE IMMEDIATE l_sql
USING p_start_date, p_end_date
RETURN sql%rowcount into l_count;
Here l_sql is is selecting record from table_1 based on p_start_date, p_end_date and inserting record in table_2.
There is some further process to be done on table_2 which I want to do only if atleast 1 record is inersted in table_2 by the select query on table_1 for this I am using RETURN sql%rowcount into l_count;
I am geting error pls-00103 for this.
Is there any way to achieve this functionality.
Thanks

Is there any way to achieve this functionality.Depends on your exact form of l_sql. Here are two ways to get the rowcount out of execute immediate:
SQL> create table emp_test as select * from emp where 1=2
Table created.
SQL> begin
   execute immediate 'insert into emp_test select * from emp';
   dbms_output.put_line ('Count: ' || sql%rowcount);
end;
Count: 14
SQL> rollback
Rollback complete.
SQL> declare
   l_count integer;
begin
   execute immediate 'begin insert into emp_test select * from emp; :1 := sql%rowcount; end;' using out l_count;
   dbms_output.put_line ('Count: ' || l_count);
end;

How to find number of lines in an internal table

Dear all,
how to find number of records present in an internal table.

DESCRIBE TABLE
Syntax
DESCRIBE TABLE itab [KIND knd] [LINES lin] [OCCURS n].
Extras:
1. ... KIND knd
2. ... LINES lin
3. ... OCCURS n
Effect
This statement determines some properties of the internal table itab and assigns them to the specified variables. The various additions enable you to determine the table type, the number of currently filled rows and the initial memory requirement.
In addition, the system fields sy-tfill and sy-tleng are filled with the current number of table rows and the length of a table row in bytes.
Notes
For detailed information about an internal table, you should use the methods of RTTS of the DESCRIBE TABLE statement.
Without the specification of an addition, the statement DESCRIBE TABLE only sets the system fields sy-tfill and sy-tleng.
Addition 1
... KIND knd
Effect
The table type of the internal table itab is determined and a corresponding one-digit identification is assigned to the data object knd. A character-type data type is expected for the data object. The identifications are "T" for standard tables, "S" for sorted tables and "H" for hashed tables. These values are also defined as constants sydes_kind-standard, sydes_kind-sorted, and sydes_kind-hashed in the type group SYDES.
Addition 2
... LINES lin
Effect
The current number of table rows of the internal table itab is determined and is assigned to the data object lin.The data type i is expected for the data object.
Note
As of release 6.10, the current number of rows of an internal table can also be determined using the in-built function lines.
Addition 3
... OCCURS n
Effect
The initial memory requirement defined during the creation of the internal table with the addition INITIAL SIZE or the obsolete addition OCCURS is determined and assigned to the data object n. The data type i is expected for the data object.
Example
Descending sorting of a generically typed internal table in a subprogram. Since sorted tables cannot be sorted in a descending order, the table type is checked to avoid an exception that cannot be handled.
TYPE-POOLS sydes.
FORM sort_descending CHANGING itab TYPE ANY TABLE.
DATA tabkind(1) TYPE c.
DESCRIBE TABLE itab KIND tabkind.
IF tabkind = sydes_kind-standard OR
     tabkind = sydes_kind-hashed.
    SORT itab DESCENDING.
ELSEIF tabkind = sydes_kind-sorted.
    MESSAGE '...' TYPE 'E'.
ELSE.
    MESSAGE '...' TYPE 'E'.
ENDIF.
ENDFORM.
DESCRIBE FIELD INTO
Note
This statement is for internal use only.
It cannot be used in application programs.
Syntax
DESCRIBE FIELD dobj INTO td.
Effect
All characteristics of the field f, its components , sub-components etc. are displayed in the field td (type description). td has to be of the type SYDES_DESC, defined in Type Group SYDES. Because of this, the type group SYDES must be integrated into the ABAP-program with a TYPE-POOLS statement .
The structure SYDES_DESC has two table-type components TYPES and NAMES:
In TYPES, the tree structure of the type belonging to f is displayed. The components of a node are stored in the table TYPES in a continuous manner. Beginning and end of the line area that represents the components are stored in TYPES-FROM and TYPES-TO. The reference to the superior node can be found in TYPES-BACK. If no superior resp. subordinate node exists, then this is marked by the value 0 (For the relevance of further components, refer to the following sections).
The names of components, types etc. are not stored directly in TYPES. Instead, the components TYPES-IDX_... hold an index in the name table NAMES. The value 0 indicates that there is no reference to the name table.
NAMES contains the possibly fragmented names in the component NAMES-NAME. If a name continues in the following line, this is indicated by an asterisk ('*') in the component NAMES-CONTINUE.
The type description table (TYPES) not only stores information about the tree structure but also further information about the type of f resp. its components. This includes especially all information that can be determined using the usual additions to DESCRIBE FIELD. In detail, TYPES contains the following columns:
IDX_NAME
Component Name
IDX_USER_TYPE
Name of a user-defined type, i.e., a type that was defined through its TYPES-statement. Derived types (... TYPE A-B) and structures from the ABAP-Dictionary are not considered to be user-defined types.
CONTEXT
For user-defined types only: The context, in which the type is defined. Possible values are defined in the constant SYDES_CONTEXT of the type group SYDES. Please only use these constants to carry out a comparison. In detail, we distinguish between the following type contexts:
SYDES_CONTEXT-PROGRAM: Program-global type
SYDES_CONTEXT-FORM   : FORM-local type
SYDES_CONTEXT-FUNCTION: FUNCTION-local type
SYDES_CONTEXT-METHOD : METHOD-local type
IDX_CONTEXT_NAME
For user-defined types only:
With a local context: The name of the FORM or FUNCTION, whose type was defined. The name of the associated program is then the first entry in the name table.
With a global context: The name of the program in which the type was defined.
IDX_EDIT_MASK
Conversion routine from the ABAP-Dictionary, is in accordance with the addition EDIT MASK at simple DESCRIBE.
IDX_HELP_ID
Help-Id when referencing to fields from the ABAP-Dictionary
LENGTH
Internal length, corresponds to the addition LENGTH at simple DESCRIBE
OUTPUT_LENGTH
Output length, corresponds to the addition OUTPUT-LENGTH at simple DESCRIBE
DECIMALS
Number of decimal digits, corresponds to the addition DECIMALS at simple DESCRIBE
TYPE
ABAP-Type, corresponds to the addition TYPE at simple DESCRIBE
TABLE_KIND
A table type is stored here for the components which represent an internal table. The same values are returned as with the variant DESCRIBE TABLE itab KIND k. Components which do not represent a table get the return value set to SYDES_KIND-UNDEFINED (see type group SYDES).
Example
Example definition of the complex data type EMPLOYEE_STRUC:
PROGRAM DESCTEST.
TYPES: BEGIN OF name_struc,
         first TYPE c LENGTH 20,
         last   TYPE c LENGTH 20,
       END OF name_struc,
       BEGIN OF absence_time_struc,
         day        TYPE d,
         from       TYPE t,
         to         TYPE t,
       END OF absence_time_struc,
       phone_number TYPE n LENGTH 20,
       BEGIN OF employee_struc,
         id         LIKE sbook-customid,
         name       TYPE name_struc,
         BEGIN OF address,
           street TYPE c LENGTH 30,
           zipcode TYPE n LENGTH 4,
           place   TYPE c LENGTH 30,
         END OF address,
         salary_per_month TYPE p LENGTH 10 DECIMALS 3,
         absent           TYPE STANDARD TABLE OF absence_time_struc
                               WITH NON-UNIQUE DEFAULT KEY,
         phone            TYPE STANDARD TABLE OF phone_number
                               WITH NON-UNIQUE DEFAULT KEY,
       END OF employee_struc.
You can determine the structure of the type EMPLOYEE_STRUC by collecting the type group SYDES as follows:
TYPE-POOLS: sydes.
DATA: employee TYPE employee_struc,
      td       TYPE sydes_desc.
DESCRIBE FIELD employee INTO td.
The following table shows a few selected columns of the type description table TD-TYPES. For a better overview, the names of the columns IDX_NAME, IDX_UERR_TYPE and IDX_EDIT_MASK have been shortened:
    |FROM| TO |BACK|NAME|UTYP|EMSK|TYPE
|--||||||--
1 | 2 | 7 | 0 | 0 | 2 | 0 | v
2 | 0 | 0 | 1 | 6 | 0 | 4 | N
3 | 8 | 9 | 1 | 7 | 5 | 0 | u
4 | 10 | 12 | 1 | 8 | 0 | 0 | u
5 | 0 | 0 | 1 | 9 | 0 | 0 | P
6 | 13 | 13 | 1 | 11 | 0 | 0 | h
7 | 17 | 17 | 1 | 12 | 0 | 0 | h
8 | 0 | 0 | 3 | 13 | 0 | 0 | C

16 | 0 | 0 | 13 | 22 | 0 | 0 | T
17 | 0 | 0 | 7 | 0 | 0 | 0 | N
Please note that the entries in rows 6 and 7 represent internal tables (ABAP-Type h). There is always an entry for the corresponding row type (rows 13 and 17) to an internal table.
The indices in the rows 5 to 7 refer to entries in the name table TD-NAMES. If you look, e.g., at row 3, you find the corresponding component name in TD-NAMES from row 7 (NAME) onward and the corresponding user type from row 5 (NAME_STRUC) onward.
In the name table TD-NAMES you find the following entries. Note that the names SALARY_PER_MONTH and ABSENCE_TIME_STRUC are stored in two parts:
    |CONTINUE|NAME                   |CONTINUE|NAME
|--|     -||--
1 |        |DESCTEST            12 |        |PHONE
2 |        |EMPLOYEE_STRUC      13 |        |FIRST

lastupdtimestamp is a column in my table.And how will this make sense in the scenario I've described, where UserA does an update before UserB, but commits the update after UserB's commited update? And add UserC and UserD and a 1000 more users to this scenario where concurrent updates happen.
What actual time does this lastupdtimestamp contain and represent? And why? How is that lastupdtimestamp used in business logic and processing? Or is it just a silly-bugger-let's-add-somekind-of-time column to that table that essentially meaningless?
Not saying that one should never add such a timestamp based column. Simply that one needs to understand WHAT it contains and it needs to be SENSIBLY used within the data model.
However, in my experience such columns are often slapped on afterwards, never featured in the actual data model designed, and is then used without a second though that the database and its data is a multi-user and multi-process system. And things happen at the same time. And things overlap (serialisation is the exception - not the rule).

Hi,
Maybe work:
For each row, ORA_ROWSCN returns the conservative upper bound system change number (SCN) of the most recent change to the row. This pseudocolumn is useful for determining approximately when a row was last updated. It is not absolutely precise, because Oracle tracks SCNs by transaction committed for the block in which the row resides
e.g.:
SGMS@ORACLE10> create table test(cod number);
Table created.
SGMS@ORACLE10> insert into test values (1);
1 row created.
SGMS@ORACLE10> insert into test values (2);
1 row created.
SGMS@ORACLE10> commit;
Commit complete.
SGMS@ORACLE10> insert into test values (3);
1 row created.
SGMS@ORACLE10> commit;
Commit complete.
SGMS@ORACLE10> select SCN_TO_TIMESTAMP(ora_rowscn),ora_rowscn,cod from test;

Searchin pattern in datbase table.(Number of rows in table :More than 3 cro

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 for a particular value of columnA. 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 3 crore 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 oracle java data mining solve the problem?

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?
Is this problem related to oracle data mining and how?
Can data mining algorthms(Minimum Description Length ,Naive Bayes,Apriori,Decision Tree,Non-Negative Matrix Factorization ,Support Vector Machine...etc..) solve my problem?
Different-2 type of queries will be fired against this table?
if i am still not clear then let me know.
