Dynamic Query Row Count

Dear HTML Gurus,
I have a SQL Query Region that returns/executes a dynamic SQL Query. Based on the number of rows a particular query returns I want to hide or show a different HTML region. I have searched all over for this kind of functionality and have come up with absolutely nothing. I would think that this would be integrated into HTMLDB because Pagination shows the total number of rows returned. Any help or direction would be wonderful.
Thanks,
James

This is how I would do it:
1. create an (hidden) item,
2. create a computation for that item and run it after submit. This computation could be a function returning the rowcount value into your (hidden) item - rowcount of my dynamic sql.
If my dynamic query is to big to be entered into the computation "container", which accepts only a limited number of characters, then I would slightly change my approach:
3. I would create a function in my schema and and call this function from the computation level - either through a simple sql query (select function(in parameter) from dual) or, again through a function returning a number.
I tested this and it worked.

Dynamic query, row to column

Hi.
Is any way to select one row as column for any table exists?
I mean some script which have table name and condition as input parameters, and prints column_name || column value;
I have tried to do it, but have some problems.
e.g. have table
create table my_table (column1 number, column2 number, column3 number);
insert into my_table values (1,2,3);It should be something like:
declare
lv_table_name varchar2(40):='MY_TABLE'; /*these are input paremeters*/
lv_condition varchar2(300):='column1=1;/*these are input paremeters*/
begin
/*body*/
end;and output should be like (may use dbms_output)
column1    1
column2    2
column3    3    Script should work for any table.
Does anybody solves task similar to this?

Maximum Row Count - dynamically change

Hi,
How can I change dynamically (eg. from some item) value "Maximum Row Count" in "Report Attributes -> Layout and Pagination"?
Is this possible?
best regards,
Jarek

Thank you for your answer, but I want to do something else.
I want to show all rows from my query in report with pagination.
The number of rows increases.
According to documentation, field "Number of Rows" sets the number of rows which I can see on one page and field "Maximum Row Count" sets the maximum number of rows which I can see on all pages (number of rows to query).
I thougth, that when I set (before page is shown) a variable from eg. query "SELECT count(*) FROM table", I will be able to put this variable name in "Maximum Row Count" field, to see all rows from my query. However this field is the numeric field and I can't put any variable name there :(
The only way to always show all records from my query is to set "Maximum Row Count" field to very high number? Is this natural way in apex? Is this only way?
best regards,
Jarek

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 )
loop
v_sql_string := ' select count(1) from ' || i.table_name;
dbms_output.put_line( v_sql_string );
--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.
Just my $ .02...

Dynamically set maximum row count in Interactive Report

Hi,
Has anyone worked out a way of dynamically setting (e.g. via select list) the maximum row count value for an Interactive Report, taking into account issues with order by when the report is filtered. I'm aware of solutions like this: http://www.talkapex.com/2010/10/apex-reports-no-limit-downloads.html but as far as I can tell this doesn't work when the report is filtered and the IR is rewritten in the background. Data sets then become unreliable because they are reordered.
Thanks,
Mike

Hi Mike,
You can do that with javascript
gReport.search('SEARCH',100)the 100 you can replace for any number you like.I have a report with filter,sorting and groups and it is gives no problem there.
any number means any number but not higher than the number you set at Maximum Rows Per Page.
You probably can mix the solution from Martin and the above code.

Column count of dynamic query

how can ı find column count of dynamic query
is there a simple way
thanks

You can use DBMS_SQL to facilitate this:
CREATE OR REPLACE FUNCTION count_sql( p_sql IN CLOB )
RETURN INTEGER
AS
        lv_cursor_id    INTEGER;
        lv_columns      DBMS_SQL.DESC_TAB;
        lv_column_count INTEGER;
BEGIN
        -- Open Cursor
        lv_cursor_id := DBMS_SQL.OPEN_CURSOR;
        -- Parse Cursor
        DBMS_SQL.PARSE
        ( c             => lv_cursor_id
        , statement     => p_sql
        , language_flag => DBMS_SQL.NATIVE
        -- Describe Columns
        DBMS_SQL.DESCRIBE_COLUMNS
        ( c       => lv_cursor_id
        , col_cnt => lv_column_count
        , desc_t => lv_columns
        -- Close Cursor
        DBMS_SQL.CLOSE_CURSOR(lv_cursor_id);
        RETURN lv_column_count;
END count_sql;

Dynamically Add Report Parameters & Get Row Count

In out Portal reports, we are inserting records into our own logging tables at the beginning of the report and updating the record at the end of the report. Currently, the sequential key has been added as a parameter so that we can access it through-out the report execution. Therefore, it displays on the parameter screen. We don't want the users to see this item. Is it possible to add it to the parameter list without having it display on the screen? Can this be done using a procedure in wwv_standard_util? Any other suggestions?
Also, we need to get the total row count of the query. Where can we get this value?
null

Different row count for select versus insert in XML query

Hi,
I encounter a situation where a SELECT * returns a different rows count than an INSERT INTO... (SELECT *) by xmltable join. This makes no sense at all!!!
In breif, I tried to convert xml data into traditional relational tables. I wrote an xml query to select data from xmltable... I checked row count. When I used "create table as select" that was the same query above, I got correct row count. However when I used "insert into select" that was the same query above, I got the wrong info in the table I just inserted.
Does any one have any idea what caused this issue? Thanks for your help.

Method for finding row count after executing query

Is there a method for finding the row count from the resultset after executing a query on a database ?

The best way: read the data from the result set. If you read it into e.g. a LinkedList, size() will tell you how many rows you got. Or you could increment a counter.
There are other ways, such as variants of ResultSet that do the read loop for you. But since you'll be doing the fetch loop anyway, those just add unnecessary work and moving parts.

Need to set the Vissible row count Dynamically

Hi,
   I have requirement where i am supposed to set the Vissible row count for a table dynmaically, depending upon the number of rows in a table.

Or use a calculated attribute.
Create an attribute in the context called calcVisibleRowCount of type integer and make it read only and calculated. Then bind that attribute to the visibleRowCount attribute of your table.
The method for the attribute looks something like this:
(this displays 10 rows per page if more than 10 records in the node, otherwise it displays the same number of rows in the table as in the context)
public int getCalcVisibleRowCount(IPrivateStartsida.ILayoutElement element)
    //@@begin getCalcVisibleRowCount(IPrivateStartsida.ILayoutElement)
          if (wdContext.nodeXXXX().size() > 10) {
               return 10;
          } else {
               return wdContext.nodeXXXX().size();
    //@@end
Note that this attribute is not created in the node that you want to count number of elements in.

How to set visible row count dynamically

i need to place input field so that user enters value for visible row count in ALV WEBDYNPRO

Hi Prabhu,
As Suggested use set_visible_row_count. First count your table entries. based on count display records.
count = LINES( lt_n_contract ).
IF count > 5.
lt_table_settings->set_visible_row_count( value = 10 ).
ELSE.
lt_table_settings->set_visible_row_count( value = 3 ).
ENDIF.
Cheers,
Kris.
