Identify the tables with data or not
HelloI want to find the tables with data and containing not data without checking each table. Is there a possible way?
Like this?
select
table_name,
to_number(
extractvalue(
xmltype(
dbms_xmlgen.getxml('select count(*) c from '||table_name))
,'/ROWSET/ROW/C')) count
from user_tables;
Or may be
select
table_name,
CASE WHEN
to_number(
extractvalue(
xmltype(
dbms_xmlgen.getxml('select count(*) c from '||table_name))
,'/ROWSET/ROW/C'))>0 THEN 'Table Has Data'
ELSE 'Table is Empty'
END
from user_tables;

According to devices/operating systems that you want to support, you could give bbUI.js a change. It works really well in most of the cases, and I think there are a lot of things you don't need to worry more because bbUI.js is just for you.
Look more at the scrollPanel example that does exactly what it takes, a part only of the entire screen of scrolling you can configure a height in the HTML source code directly.

Hello
I have a loop 'for' which can take different number of iterations according to the number of measures that the user wants to do.
Inside this loop, I'm auto-indexation four different 1 d arrays. This means that the size of the tables will be different in the different phases of the execution of the program (the size will equal the number of measures).
My question is: the auto-indexation of the tables with different sizes will affect the performance of the program? I think it slows down my Vi...
Thank you very much.
My first thought is that the compiler to the LabVIEW actually removes the Matlab node because the outputs are not used. Once you son upward, LabVIEW must then call Matlab and wait for it to run. I know from experience, the call of Matlab to run the script is SLOW. I also recommend to do the math in native LabVIEW.

I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help
I don't understand. You use vo and eo for you to use business components.
Again, this kind of code call in trouble.
You must post the changes to make them visible to the eo find vo. You must then run the query for the changes in the business layer strips then you must update the iterator he table is based on.
In your code I see that happen, hooch maybe because it is more often than not formatted and undocumented.
My advice is to do a small test case that you can manage with easy sql. Once you get it to run transfer you the results to the actual application.

Fill the table with random values
Another thing I've come across is this:
the table name is LOR, who has 3 fields NUMBER, DATA, TEXT with number, date and varchar2 data type.
On a page, I have a text field where if I write 3, then it would add 3 lines to the table with predefined values ("number, something like 2222, for 12 January 09, and for text, something like" Lorem ipsum dolor sit amet, 195kgs adipisicing elit"). So basically, with the number that I give, it populates the table with lines... How can I do this? Thanks for helping meINSERT INTO LOR SELECT 222 , sysdate , 'you string' FROM dual CONNECT BY level <= :Pxx_

Name of the table list ALL_TABLES but not in TABS
Hello
I was trying to programatically check if a table is exist or not and insert the records if exist (via Java). I see a weired behaviour where when I check the metadata through my connection, I see this table_name in it (don't think there is an error in the logic), but when I try to insert a record after that, he lifts - java.sql.SQLException: ORA-00942: table or view does not exist.
When I manually check the DB, I see this table to table ALL_TABLES but not in TABS (not sure what is the same difference between those two, and that is the right place to check), desc < table_name > is also a failure...
I'm really confused if the table is exist or not...
Any help is really appreciated.
Thank you
