Query to get the number of records
Hi allI would get the number of records in all tables in a schema. I don't want to run select count (*) of < table name >, because there are nearly 400 paintings. So I need a generic quqeyr that will give the recordcount for all tables.
Experts good help yourslef to tide me over.
Do you need a specific account? Or an approximate count is sufficient? Do you use the RBO and CBO?
If you use the CBO and want an approximate count, column NUM_ROWS USER_TABLES should give you what you want.
If you need a specific account, you will have full scan all tables. You can automate this process via SQL dynamic, i.e.
DECLARE
l_cnt INTEGER;
BEGIN
FOR x IN (SELECT table_name FROM user_tables)
LOOP
EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' || x.table_name INTO l_cnt;
dbms_output.put_line( 'Table ' || x.table_name || ' has ' || l_cnt || ' rows.' );
END LOOP;
END;
Lawrence was also a [solution based on XML Query | http://laurentschneider.com/wordpress/2007/04/how-do-i-store-the-counts-of-all-tables.html] to count all the rows in each table in a schema.

How get the number of records in a DataGrid?
I was hoping that it would be easy, but it didn't turn out as well. I need two things:
1 - the total number of records returned in an ArrayCollection collection
2 - the total number of rows in a DataGrid
Explanation: I have an application that gets data using CF and returns that data to a DataGrid control. I need to get the total number of records returned. I then filter or query the data and complete a second DataGrid with a subset of records. Then, I need to get the number of records in the second DataGrid.
Can anyone provide a good example of how do these two things?
Thank you

Dg.dataProvider.length is the number of records in the ArrayCollection collection
Dg.rowCount is the number of visible lines.

good way to get the number of records in a block
Work with form 11g.
I want to know the amount of files that are currently in a block, being that the : system.cursor_record you could get if you issue a built-in last_record .
It's the kind of thing that should be easy to get with a get_block_property, but I looked for the property and I have not found.
There are various fo get_block_property properties that relate the number of records, but none seems to fit what I need. The best is QUERY_HITS. It works great when you run just a query (showing all records), but if you add or delete records, it retains its old value, so it doesn't help.
The trick of last_record is very dirty (and implies the navigation, which is worse)... Can you think of something better?
I tried with a glimpse at the point and it works, but I don't know if it's reliable, and it is still too expensive for something that should be in a property
My advice would also be the preview to the point

SQL query to get the number of days monthwise
Hello
I'm new to sql, can someone please tell me query to find the number of days between the two dates months wise.
say
FIRSTDATE last date
21/03/2011-25/06/2011
March April May June
9 22 23 18Hello
Welcome to the forum!
Here's one way:
WITH all_dates AS ( SELECT start_date + LEVEL - 1 AS a_date FROM ( SELECT TO_DATE ('21/03/2011', 'DD/MM/YYYY') AS start_date , TO_DATE ('25/06/2011', 'DD/MM/YYYY') AS end_date FROM dual ) CONNECT BY LEVEL <= end_date + 1 - start_date ) SELECT TO_CHAR ( TRUNC (a_date, 'MONTH') , 'fmMonth YYYY' ) AS month , COUNT (*) AS num_days FROM all_dates WHERE a_date - TRUNC (a_date, 'IW') < 5 GROUP BY TRUNC (a_date, 'MONTH') ORDER BY TRUNC (a_date, 'MONTH') ;
What is a 'working day '? I guess you mean every day except Saturday or Sunday, but the query aboveare sometimes figures less than you have asked:
MONTH NUM_DAYS --------------- ---------- March 2011 9 April 2011 21 May 2011 22 June 2011 18
Are a few days working on Saturday or Sunday? How do you get the 22 working days in April 2011 and 23 in may?
SQL is good at obtaining results with a variable number of rows, but you have to say exactly the desired number of columns when you write the query.
If you really need the output of the way you said, with any number of columns, then watch in swing or a grouping of the chain . See the FAQ forum

Hello
I need where there are quick dashboard that selects the date, second interval column consists of >, <, = and the third column is seen number (in days)
for example, the user enters: 12 18, 2015, <, 9. here I report who should get the data (records) 9 days earlier from the date specified (from 12/10/2015 to 18/12/2015).
Similarly for > =.
How to get there. I'm unable to write the script and I use the column date in my report. Ask that you please advice how to solve this problem.
Please find below the screen for reference.
Kind regards
Chandra Khalil.
Hello
Not exactly why you're doing the report this way. If the user must select, basically, a period of dates, would not easier to have a column of data with a between the operator and the user would select 2 dates (upper and lower intervals)?
In any case, it is possible to achieve what you want to do as a result of your approach. You could use when's CASE and have a more complex filter, but I think that it is better to have a few nested filters where you use the range operator to determine what date filter that you use (see image below)
Some notes about my filter. First of all, I am making the assumption that the operator is "=", then the number of days specified must be ignored and you just return the data for the selected date. You will notice also that in my filters, I got a cast so far, but if you are using a column that is already a timestamp so it won't be necessary.
This should achieve what you want.
See you soon,.

Select * from object

If you want just the County
select count(*) from all_objects where owner='PREMIER' AND OBJECT_TYPE='FUNCTION' AND OBJECT_NAME LIKE'%FDR_%'
If you want the number on each line in addition to the line-level data
select a.*, count(*) over () cnt from all_objects a where owner='PREMIER' AND OBJECT_TYPE='FUNCTION' AND OBJECT_NAME LIKE'%FDR_%'
