have some one a sample script or query for exaple;

But from the subject line I could read as you like to know the record count of all tables in a schema.
DECLARE
ct NUMBER;
BEGIN
FOR i IN (SELECT TABLE_NAME FROM USER_TABLES
LOOP
      EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM '|| i.table_name INTO ct;
      DBMS_OUTPUT.PUT_LINE('Table_name:'||i.table_name||' Count :' ||ct);

Count rows from multiple tables using SQL only

Hi, I know this has probably been answered before, but I couldn't find the answer anywhere. Please help.
I'd like count(*) [rows] for all tables in database using SQL only - no PL/SQL
The result should be something like:
Table RowCount
DBA_TABLES 1000
DBA_USERS 50
etc.
Thanks!

Count rows from several tables

hello,
im trying to count row from multiple tables
for example i need the select statement to produce the following
table_name count
table1 5
table2 6
table3 3
i came up with the following script but it counts the number of tables i have
select object_name, (select count(*) from user_tables where table_name = object_name) from all_objects
where object_type = 'TABLE'

What is the problem with native dynamic sql when counting rows in all table

what is the problem with native dynamic sql when counting rows in all table?Giving an error "table or view does not exist". Thanks.
DECLARE
v_sql_string varchar2(1000);
v_no_of_rows number;
BEGIN
for i in ( select table_name from all_tables )

--execute immediate v_sql_string into v_no_of_rows;
end loop;
END;

Usually your problem can be described with 'Who cares'. I mean, for what reason do you do this? I doubt that there's a business need to get 100 % accurate answers for this. Normally such things are used to get a picture about the growth of data.
Personally I would prefer to have up-to-date statistics for all tables and just query the number of rows from there. Sufficient for me in < 99 % of all cases.

Counting Rows in a Table

I'm new at this mysql stuff and can't seem to figure out how to write the code for querying the database for the number of rows in a table. I can get a connection to the database and have done some basic commands like SELECT * FROM TABLE using rs.next().
Can somebody help me out with the java bit for this..?
select (count*) from myTable;
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT COUNT(*) FROM myTable);
Thanks,
amy

Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT COUNT(*) FROM myTable");
while( rs.next() )
// Should run 1 time only
System.out.println( "count of rows: " + rs.getInt( 1 ) );
rs.close();Try out, if I haven't overseen something.
The trick is: your query brings you a resultset containing 1 row with 1 column: the int value.

Count rows in a table being retrieved from dba_segments

Hello guys,
I was wondering how can I count the rows in a table that is being retrieved from dba_segments.
-- I am getting the table name from dba_segment
-- Is it possible to count the number of rows in that table at the same time?
-- If not, is there an alternative step without analyzing the table or schema, then getting the result from num_rows in all_tables?
I want the count code to add to the select statement..
SELECT owner, segment_name , segment_type, partition_name, bytes
FROM   dba_segments
WHERE owner = UPPER( v_schema )
ORDER BY segment_name;I try to add this to the select statement. count(segment_name), but that did not work.
Any direction(s)?

Counting rows for db tables with 500 million+ entries

Hi
SE16 transaction timesout in foreground when showing number of entries for db tables with 500million+ entries. In background this takes too long.
I am writing a custom report to get number of records of a table and using OPEN CURSOR concept to determine number of records.
Is there any other efficient way to read number of records from such huge tables.
        OPEN CURSOR l_cursor FOR
        SELECT COUNT(*)
           FROM (u_str_param-p_tabn) WHERE (l_tab_cond). " u_str_param-p_tabn is the table name in input and l_tab_cond is a
          DO.                                                                              " dynamic where condition
            FETCH NEXT CURSOR l_cursor INTO l_new_count.
           PACKAGE SIZE p_pack.
            IF sy-subrc NE 0.
              EXIT.
            ELSE.
              l_tot_cnt = l_tot_cnt + l_new_count. " l_tot_cnt will contain number of records at end of loops
              CLEAR l_new_count.
            ENDIF.
          ENDDO.
          CLOSE CURSOR l_cursor.

Hello,
For sure it is a huge number of entries!!!
Is any key-fields?
Use a variable to keep a counter of the key-fields , for example row_table and also a low and high variable .
Try to use a do-loop and in this loop use:
do .
low_row = row_table.
low_high = row_table + 200.000.:increse the select every 200.000 entries
Do "select statement into table" based on the key-fields
For example : if the key-field is the docnr,
Do a "select into table itab where docnr >low_row
                                        and docnr < low_high"
Count the lines of itab and keep them in a variable.
free the itab.
enddo
Good luck.

Count of rows of a table in header

Hi Experts,
I am stuck in a tricky scenario.
I need to get the count of rows of a table in a webi report in the header of the report.
And the count should change dynamically according to the filtering done on the table.
For eg.
If I have 10 countries in a table, so table has 10 rows.
Now the count on header should show 10.
Now if we filter the column to 5 countries, the count on the header should change to 5.
Any Idea's.
Regards,
Gaurav

Nops
It doesn't work.
Let me reframe my issue again:
I dragged country object on my report.
UK
US
JAPAN
CANADA
Now lets say in the report title, I write the formula as =Count(country)
It will give me 4.
Now I clicked on the column country and applied filter i.e. country = US ; UK
Now the block shows
UK
US
In the header the cell still shows 4, which I want to see as 2.
Any ideas....?
Thanks
Gaurav

How to get count of rows for a table?

Hi,
How to get count of rows for a table and secondly, how can i have access to a particular cell in a table?
Regards,
Devashish

Hi Devashish,
WdContext.node<Your_node_name>().size() will give you the no: of rows.
This should be the node that is bound to the table's datasource property.
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value); will select the row at that particular index.
You can access an attribute of a particular row as
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value).get<attribute_name>();
Hope this helps,
Best Regards,
Nibu.

Row Count mismatch in a table

Hi,
I am having a table and if i do count(*) , the total rows are coming 36882, but if i take export backup or select * from table, it is showing 7225. Any help to trace out the problem is highly appreciated. I am using oracle 9.2.0.4 in aix 5.3
Regards
Sridhar

Is the "table" being selected from and rows counted, an actual table? Confirm using ALL_OBJECTS. What is the table type? Hash?
s. I have counted in the actual table only. From all_objects, the object type is TABLE.
Is FGAC (Fine Grain Access Control) used? Have you tried the select count or export from the SYS schema (exempt from FGAC)? Have you looked at the execution plans?
No FGAC is used in that table. Export taken from sys also. Then also the same problem.Execution plan has been verified.
If full table scan is performed, then less number of rows are returned. If the index hint is used and give count(*) or select * from table_name, all rows are returned.
What happens when a CTAS is done against this table - what is the rowcount of the new table?
if we give select * from alone then 7000+ rows alone created in new table.
If index hint is used for ctas, then all the rows nearly 38000 rows are created in the new table.
There are numerous sanity checks to do, before "accusing" a table of showing incorrect and buggy row count totals
- All levels of trouble shooting has been already done and no use. This is the second time, i am facing this problem.
Hence raised the issue and requested help from others.

Counting all the rows in a table

I've just come across what I think is a big oversight in the Power Query UI: it doesn't seem to be possible to find the total number of rows in a table using just the functionality available in the UI. I can do this very easily if I write my own expression
using Table.RowCount(), but I would have expected to be able to do this through the UI. At the moment, when I go to the Group By dialog (which is where I'd expect to be able to do this) and delete all the columns in the Group By section the OK button gets
greyed out.
Am I missing something here?

Hi Miguel,
No, what I was talking about was to be able to use the Group By dialog and have no column to group by - that's to say, I'd just want to be able to count the number of rows in a table (or return the sum of all values in a column, or the min/max etc) and return
a single value. I know I could do this by inserting an artificial column that only contains one distinct value, and using that in the Group By, or by writing my own expression that uses Table.RowCount(), but it seems like a very basic operation that should
be easier to do in the UI.
