Counting Column in Table

good day all,
JSC provides wonderful sorting features out of the box for tables and these allow my users to look at a dataset from many different angles without making a new query.
however my users are very interested in placings so if they sort by a particular column and focus on a row, they want to know what position is that row according to the current sort.
in reality i simply want a column that has counting numbers 1 to x that remain that way regardless of what column the data is sorted by.
i know this may be a bit confusing, but please let me know if you have any ideas as to how i can accomplish this. also if this is not clear please let me know and i will clarify anything that you don't understand.
thank you.
take care
kroikie

haha,you can give a varible in session bean

How to get row count(*) for each table that matches a pattern

I have the following query that returns all tables that match a pattern (tablename_ and then 4 digits). I also want to return the row counts for these tables.
Currently a single column is returned: tablename. I want to add the column RowCount.
DECLARE @SQLCommand nvarchar(4000)
DECLARE @TableName varchar(128)
SET @TableName = 'ods_TTstat_master' --<<<<<< change this to a table name
SET @SQLCommand = 'SELECT [name] as zhistTables FROM dbo.sysobjects WHERE name like ''%' + @TableName + '%'' and objectproperty(id,N''IsUserTable'')=1 ORDER BY name DESC'
EXEC sp_executesql @SQLCommand

The like operator requires a string operand.
http://msdn.microsoft.com/en-us/library/ms179859.aspx
Example:
DECLARE @Like varchar(50) = '%frame%';
SELECT * FROM Production.Product WHERE Name like @Like;
-- (79 row(s) affected)

GETTING ROW COUNTS OF ALL TABLES AT A TIME

Is there any column in any Data dictionary table which gives the row counts for particular table..
My scenario is...i need to get row counts of some 100 tables in our database...
instead of doing select count(*) for each table....is there any way i can do it?
similary How to get column counts for each table..in database .For example
Employee table has 3 columns...empid,empname,deptno....i want count(empid),
count(empname),count(deptno) ...is there any easy way for finding all column counts of each table in data base? is it possible?

Why does "select count(mgr) from emp" return null and not 13?Good question ;)
Seems that xml generation in principle can't handle »counting nulls«:
SQL> select xmltype(cursor(select null c from dual)) x from dual

Finding column and table name

Hi,
I need to find out that '101c_0000000018' value is which column and table of database.
Is there a way to find it? I am looking for table and column which is storing this data.
Thanks
Sandy

It's possible but performance is going to be horrible.
Assuming the data is stored in a CHAR or VARCHAR2 column, something like
DECLARE
l_value VARCHAR2(100) := '101c_0000000018' ;
l_cnt   PLS_INTEGER;
l_sql    VARCHAR2(1000);
BEGIN
FOR x IN (
      SELECT table_name, column_name
        FROM dba_tab_cols
       WHERE owner = <<name of schema>>
         AND data_type IN ('CHAR', 'VARCHAR2' )
LOOP
    l_sql := 'SELECT COUNT(*) FROM ' || x.owner || '.' || x.table_name || ' WHERE ' || x.column_name || ' = :1';
    EXECUTE IMMEDIATE l_sql
      INTO l_cnt
     USING l_value;
    IF( l_cnt > 0 )
    THEN
      dbms_output.put_line( 'Found the value ' || l_value || ' in owner = ' || x.owner || ' table name = ' || x.table_name || ' column name = ' || x.column_name );
    END IF;
END LOOP;

Collumn Count from Database Table

Hello,
I wan't to get a Collumn Count from a Table in my Database, but I don't know how to do that.
I use a ResultSet, and if i press ctrl + spacebar in NetBeans I get a list of all kind of things I can get out of the result set but I can't find CollumnCount anywhere.
I thought I could use a try catch statement like this:
try
for(i=1; i<999; i++)
myResultSet().getString(i);
catch( Exception e )
AantalKolommen = i--;
But everytime I get an Exception over Invalid Crursor State and "i" keeps standing on 1.
Does anybody know a way to find out how to get a collumns count????

Dynamic row counter column in Adobe Forms

Hi Guys,
My table in Adobe Forms is dynamically created with Conditional Breaks. I want to display 1st column as Sr.No. displaying row counter for tables on each page.
Anyone have idea how to achieve the same.
Sr.No
Name
Address
1 (generated in adobe forms dynamically)
xyz
awsaxa sadsad
2 (generated in adobe forms dynamically)
abc
asds sad ads
so on......

Hi Guys,
Not able to find any counter variable for table. So what I did is inserted the counter logically before calling Adobe forms driver program.

Max columns per tables

H,
What is max number columns per table in database express edition ? I have requirement of creating a table with 100 columns but it seems database only accepts table with 94 columns.any way out ?

Hi Hardy,
Here's a quote from Oracle's SQL documentation:
"The absolute maximum number of columns in a table is 1000. However, when you
create an object table or a relational table with columns of object, nested table, varray,
or REF type, Oracle Database maps the columns of the user-defined types to relational
columns, in effect creating hidden columns that count toward the 1000-column limit."
Where are you seeing the "94 maximum"?

Counting columns based on set criteria?

Hello gurus,
I've been trying for the past hour to count the number of columns that have a certain condition met, that is two check boxes are ticked.
For example:
I want to count the number of columns where both Apples & Oranges is TRUE.
I've tried combinations of SUMIF, COUNTIF, IF, & COLUMNS and really don't have a clue. Searching the web for Excel examples doesn't help and I can't find anything like this on this forum.
Any help would be much appreciated.
Regards,
Dr Paul Martin

The closest I've been is this:
=COUNT(AND(Table :: Apples,Table :: Oranges))
The AND function only generates one result (TRUE/FALSE) which I convert to a number (1/0) with the COUNT function.
The problem is that I can't count a range of columns that meet this criteria.... it will only give me one result not the total number of positive results.
What I need is something like this:
=COLUMNS(AND(Table :: Apples,Table :: Oranges))
Except that generates an error "COLUMNS requires a range but found a boolean instead". I guess I can't mix them up?
Regards,
Dr Paul Martin

Counting rows on table with TEXTIMAGE_ON

For many-columned fixed length files I created and loaded this table:
CREATE TABLE [dbo].[Fixed_Length_Text_Files](
[Line] [text] NULL,
[Text_File_Id] [bigint] NULL,
[ID] [int] IDENTITY(1,1) NOT NULL,
CONSTRAINT [Fixed_Length_Text_Files_ID] PRIMARY KEY CLUSTERED
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
Any way to get a row count on this table for a specific text_file_id?
Because of the text column, the result is always 0.
Thanks,

Select count(*) just gets 0, filtered or not.
Someone suggested Select count(1).
I'm going to try that.

Getting counts from detail tables

I have multiple record bock that displaye a list of cell ids and their attributes; each record also displays record counts of its 3 detail tables.
Originally, the POST-QUERY trigger select the counts (3 detail tables) as part of the data block for each record (or cell id). There are over 16K records, so each record query issues 3 selects. The whole query toke over a minute. I was asked to improve the retrieval time.
At first I thought perhaps I could put the 3 counts in 3 separate data blocks and issue one query each in a "select cell_id, count(*). . . group by cell_id" but scrolling would not synchronize with the other blocks. So I dropped that idea.
Next, I added a program unit from which the WHEN-NEW-FORM-INSTANCE trigger calls after execute_query. It issues "select cell_id, count(*). . . group by cell_id" (one for each detail table) and fills the count columns in the original data block. However I need to set the block property Query All Records to YES so that the cell ids and attributes are filled first. That means that before the form comes up it has to retrieve all records. That saves me about 10-15 seconds od retrieval time and I lose the ability to quickly bring up the form.
Then I looked at using dfferent Query Data Source Types. I don't think I could do one query with counts of detail tables. Besides, some items (attrinutes) of the cell are upate-able.
Any ideas and suggestions will be appreciated.

Yes. I suggested adding columns to the master tables and introduce stored triggers.
Since the change is not trivial, according to management, they put in on hold.I'm not sure if you misunderstood my suggestion or were responding to a different post. The query I wrote was for counting the detail records on the fly rather than populating new columns. If you include the counting in your main query then you will probably not have a much slower query than if you don't show any counts at all. Scrolling through the block will be no slower than if you had no counts, because no extra processing needs to be done. (You'll still have to fetch the detail blocks for each row, so moving to the last record will still be slow - that's a bad indicator of the performance of a query.)
For example, fetching the objects for each user takes 5 seconds. When I include the number of tables, indexes and constraints for each user within the query the time only goes up to just under 9.

Reg:How to delete the column in table control also from database table.

Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.

Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab.

How to Enable and Disable column in Table Control.

Hi all,
I want to make certain column of Table control as Enable or Disable on Button action.
Enable means ready for input and Disable means not ready for input.
Please send me sample code.
Thanks in advance.

Hi Vipin,
    You have to loop through the table columns to set the properties in the PBO of your screen.
Here is the sample solution.
delcare a workarea for the columns in the table control in your top include.
Table Control .
CONTROLS: TAB1 TYPE TABLEVIEW USING SCREEN '0100'.
DATA: WA_COLS LIKE LINE OF TAB1-COLS.
in your screen
PROCESS BEFORE OUTPUT.
MODULE INTIALISE_100.
*&      Module 0100_INTIALISE OUTPUT
MODULE INTIALISE_100 OUTPUT.
    LOOP AT TAB1-COLS INTO WA_COLS.
      WA_COLS-SCREEN-INPUT = 1.
      MODIFY TAB1-COLS FROM WA_COLS TRANSPORTING SCREEN-INPUT.
    ENDLOOP.
ENDMODULE.                 " 0100_INTIALISE OUTPUT
modify the screen-input property as required for the table control columns.
Please provide points if helpfull.....

Tabular Form: Conditional column based on another column in table/form?

Hi!
I have 4 columns in table A:
number (the question number)
question (the question to be asked)
type (TEXT, LOV are the 2 valid values)
answer (the answer with text or a selection from the lov table below)
I have 2 columns in table B:
number (the question number)
values (a single value for the lov's)
In table B there can be mutiple rows for each number. Table A and table B
join on the number.
I want to build a tablular form on table A where for each row either a text
box or a select list is displayed depending on the contents of the type column.
So row 1 would display a text box when the type value is text; row 2 would
display a select list when the type value is lov.
Is this even possible? How do I refer to the type column in the conditional for the
answer column? I am guessing that I will need to have 2 answer columns one
that displays when the type column is TEXT and one that displays when the
type column contains LOV. This is OK. Setting up the conditional is display is the issue at this point.
Hopefully I have explained this well enough! :)
Thanks!
Dave Venus

Hi Dave,
Sorry for not responding sooner - I finish work at 3pm GMT.
I'll take your first question first (3:28PM posting according to my display - not sure if you are on GMT time?):
As far as I understand it, using the select_list_from_query() function generates the options that are required in the select list as HTML tags. Each instance of this function should create a SELECT tag and the results of the query should generate one or more OPTION tags within it.
Second question (4:20PM posting):
The HTMLDB_ITEM functions are listed in the documentation - here's a link to the online version:
http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14303/api.htm#sthref2524
Most of the examples that I have seen have been on this forum - simply search for HTMLDB_ITEM or one of its functions.
I tend to leave the generation of tabular forms to the wizard as much as possible. The only exceptions are when I need to have access to more than the Primary Key for a row but don't want to show the field on screen. There are examples on the forum about concatenating the HTMLDB_ITEM functions into a single value - this hides ID fields from the user but makes them available to PL/SQL code.
Third question (5:29PM posting)
I did try using DECODE in my questionnaire but not for the feature that you needed. Originally, I wanted to use this to display one of a number of different fields (ie, my date, number or string field as appropriate to the question) but this didn't help as I couldn't get back to the right field during the update. If you have decode working for the select lists, then that's great!
The first column should be hidden or sitting behind a checkbox as this should be the Primary Key for the row and should not be editable by the user nor would it normally be displayed.
As long as your select statement creates the correct output (albeit that you may need to work on the layout!), you should have an updatable form. However, you will need to have the MRU processes in place and the appropriate buttons that trigger these. When I did my questionnaire, I created the form using a wizard to get all of the processes and buttons and then changed the select statement. If you haven't got the processes and/or buttons, we can go through adding these onto your page.
Last question (9:08PM posting)
As explained above, column 1 should normally be hidden. The INPUT tag you detail above is what I would expect to see. The value="6" attribute indicates that 6 is the Primary Key for that row - every row will have the same tag but different values for the "value" attribute. So, if it is hidden and these are the tags you see doing a View Source on the page, then everything is correct.
OK. So now we have the data on screen and (hopefully?) we have the correct processes and buttons on the page.
The next step would be validation and update of the data.
Validation of the data can be handled by a normal page process - I can let you have example code if you want to validate the data (this will also explain how to loop through the rows - there are also methods that you can use to do this in javascript if you want). Updates should be handled by the processes and buttons on the page - again, if you haven't got these we can go through adding them in (although, if you haven't yet formatted your page, you may find it quicker to copy your select statement and create the page again using the same select statement).
ORA-20001 errors are user defined errors. Do you mean the "data has changed" errors? If so, you will probably need to include the MD5 checksum functionality (it's shown in the document linked above).
Finally, we'll keep this thread going so that you have all of your workings and my responses in one place, if that's ok with you?
Regards
Andy
