Get the count of rows in a table control

Hi Experts,
How do I get the count of the rows in a table control during run time.
I am developing a BDC in which I have to check all entries in a table control.
My requirement is to get the total number of rows in a table control dynamically.
Thanks
Kumar

Hi,
Use a variable when u r passing the records from the internal table to the screen fields
and display the same.
I think this idea may help u.
And pls explain me ur requirement clearly.

Getting the count of rows present in the oracle table

Hi all,
i want to get the total number of rows present in the sql table to the appmodule.
After applying the some view criteria to the view object. if it try with getallrowsinrange it was giving count of rows present in the viewobject but i want total number of rows present in the sql table.
How can i get that
I am using jdev 11.1.1.5
Thanks in advance

I threw something together, quick and dirty, feel free to optimize.
Assuming that you want the table count, I put the code into a EntityDefImpl subclass since this is what represents a table in the middle-tier.
public class EmpDefImpl
      extends EntityDefImpl {
   * This is the default constructor (do not remove).
public EmpDefImpl( ) {}
//~ Methods ****************************************************************************
public long getTableRowCount( DBTransaction transaction ) {
    String query = getQuery( );
    String countQuery = String.format( "SELECT COUNT(*) FROM (%s)", query );
    long count = 0;
    ViewObject vo = transaction.createViewObjectFromQueryStmt( countQuery );
    try {
      vo.executeQuery( );
      Row row = vo.first( );
      Number number = (Number)row.getAttribute( 0 );
      count = number.longValue( );
    } finally {
      vo.remove( );
    return count;
}Depending on your type map, you might not get a oracle.jbo.domain.Number, but something else, so the cast might need correction.
Usage example:
public class EmpEditViewImpl extends ViewObjectImpl {
public EmpEditViewImpl() {
protected void executeQueryForCollection( Object object, Object[] object2, int i ) {
    super.executeQueryForCollection( object, object2, i );
    EmpDefImpl def = ( EmpDefImpl )getEntityDef( 0 );
    long tableRowCount = def.getTableRowCount( getDBTransaction() ) );
    // Do something with it
}As you can see, the code is pretty generic. You might also be able to put this into an ADF extension base class.

How to get the Number of lines displayed in table control in bdc

Hi,
when we write a bdc for a standard transaction, if we encounter a table control, we fill the values for each record like field(01), and the second record field(02) .......and so on..
if only 3 records are displayed in the screen and if we have 5 records to be filled in the table control, how to write the logic for that?
how to track of how many lines are getting displayed in the table control .. again it depends on the screen resolution i think..
useful answers will be rewarded

Hi,
Here is the solution code for this :-
data for controlling paging on screen 0102
DATA: W_MAXLINES(2) TYPE N,
W_NEXT_LINE(3) TYPE N,
W_PAGE(1), "y = page forward, n otherwise
W_SCRLEN(2) TYPE I,
W_SCRLINE(2) TYPE I.
DATA: BEGIN OF W_HDR.
INCLUDE STRUCTURE D020S.
DATA: END OF W_HDR.
DATA: BEGIN OF W_FLD OCCURS 100.
INCLUDE STRUCTURE D021S.
DATA: END OF W_FLD.
DATA: BEGIN OF W_LOG OCCURS 20.
INCLUDE STRUCTURE D022S.
DATA: END OF W_LOG.
DATA: BEGIN OF W_MC OCCURS 20.
INCLUDE STRUCTURE D023S.
DATA: END OF W_MC.
DATA: BEGIN OF W_DYNPRONAME,
PROGRAM(8) VALUE 'SAPMM60X',
DYNPRO(4) VALUE '0102',
END OF W_DYNPRONAME.
FORM GET_MAX_LINES.
set w_maxlines to the number of var-loop occurrences on the screen so
that we know when to page forward on screen 0102
also initialise w_next_line to zero for GET_NEXT_LINE
this subroutine caters for all cases - including screens without loops
CLEAR: W_MAXLINES,
W_NEXT_LINE.
IMPORT DYNPRO W_HDR
W_FLD
W_LOG
W_MC
ID W_DYNPRONAME.
LOOP AT W_FLD WHERE LTYP EQ 'L'.
MOVE W_FLD-LINE TO W_SCRLINE. "first var-loop line
MOVE W_FLD-LBLK TO W_SCRLEN. "depth of loop block
EXIT.
ENDLOOP.
IF SY-SUBRC EQ 0
AND W_SCRLEN NE 0.
sy-srows = total no of lines on screen
w_scrline = actual first line of loop so that
w_scrline - 1 = number of heading lines (before loop)
4 = no of lines at top of screen - command line, pushbuttons, 2 ulines
3 = no of lines after loop - uline & Page count
w_scrlen = no of lines in loop block
w_maxlines = sy-srows - ( wscrline - 1 ) - 4 - 3
and then 1 less but not sure why!
W_MAXLINES = SY-SROWS - W_SCRLINE - 1 - 4 - 3.
W_MAXLINES = W_MAXLINES - 1.
W_MAXLINES = W_MAXLINES DIV W_SCRLEN.
ELSE.
MOVE 99 TO W_MAXLINES. "this required if no screen loop
ENDIF.
ENDFORM.
FORM GET_NEXT_LINE.
set w_page if page forward is required
W_NEXT_LINE = W_NEXT_LINE + 1.
IF W_NEXT_LINE GT W_MAXLINES.
W_NEXT_LINE = 1.
W_PAGE = 'Y'.
ELSE.
W_PAGE = 'N'.
ENDIF.
ENDFORM.
Hope it helps.

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

Count of rows from different tables.

Hi Friends,
I have 4 tables with a common column name "ID". I would like to get the count of rows from all the four tables which has the same ID.
Ex
select count(a.id) from table1 a,table2 b,table3 c,table4 d where a.id=b.id=c.id=d.id=5;
please suggest me some solution

may be thsi?
select count(a.id) from table1 a,table2 b,table3 c,table4 d
where a.id=b.id and a.id=c.id and a.id=d.id and a.id=5;

Need Query to that generate count of rows of all tables

Hi
i need a query which gives the result of no.of rows in talbe and coresponding table name.
And then i need to compare the same with other DB schema
Thanks in advance

Hi User,
We can also get the count of rows for all the tables associated with a User, we can create a custom function which
uses the table name to return results.
CREATE OR REPLACE FUNCTION TAB_ROWS_CNT (TAB_NAME IN VARCHAR2)
   RETURN NUMBER
AS
   TAB_CNT   NUMBER :=0;
BEGIN
   EXECUTE IMMEDIATE 'select count(*) from ' || TAB_NAME
      INTO TAB_CNT;
   RETURN TAB_CNT;
END;And query,
SELECT TABLE_NAME, TAB_ROWS_CNT (TABLE_NAME) ROW_CNT
FROM USER_TABLES;Which gets us the count of Individual Tables for a user.
This is an just that we can do in this way also. But, use which is optimal.
Thanks,
Shankar

Getting the no. of rows returned from the resultset

Could somebody tell how can I get the count of rows from the resultset object.
Thanks a lot in advance

hmmm 20,710 topics and 69,000 odd posts and no one has EVER asked this question before.. it's a miracle....

Get the Count for each row

I'm trying to get the count for each row to total count for each month
Something like this
Hardware | Jan
Monitors | 5
Processors | 137
Printers | 57
etc........
How can I write a query for this. I can get the Hardware column but don't know how to get the next column.

If you can provide more data like sample input DML statements it would have been wonderful..
Assuming is , you need a pivot. Here is an article on basic Pivot..
http://sqlsaga.com/sql-server/how-to-use-pivot-to-transform-rows-into-columns-in-sql-server/
something like this may be..
DECLARE @Input TABLE
Hardware VARCHAR(20),
[Date] VARCHAR(20)
INSERT INTO @Input VALUES('Monitor', '01/01/2014'), ('CPU', '01/01/2014'), ('Monitor', '01/03/2014')
, ('ABC', '01/01/2014'),('Monitor', '02/01/2014')
;WITH CTE AS
SELECT Hardware, LEFT(DATENAME(M, [Date]),3) AS [MonthName] FROM @Input
SELECT *
FROM
SELECT Hardware, [MonthName], COUNT(Hardware) AS Count FROM CTE GROUP BY Hardware, [MonthName]) a
PIVOT (MAX([Count]) FOR [MonthName] IN ([Jan], [Feb])) pvt
Please mark as answer, if this has helped you solve the issue.

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.

How to get the number of rows in a DB-Cursor

When i open a database cursor i do not know how much rows are stored in the cursor. To solve this problem i have to send a 'select count(1) ...' to get the number of rows before i set up the cursor. I think that this is not very clever and could possibly cause performance problems. But i need the num of rows to show the percentage of processed rows. Is there any other way to get the num of rows? May be by checking the cursor directly?
Please help!
Thanx a lot

In order to find out how may rows are going to be processed, oracle has to visit every row. So with a cursor, there is no property that will accurately reflect the number of rows until you get to the last one. That said, you could use
select count(*) over() as row_count, <rest of your columns> FROM <your table>
which will give you the total row count agaist each row in the result set. There are performance penalties involved but they will be less than issuing the query twice, once to get the count and once to get the rows.
Have a look on asktom for some very usefull info about all this.

By which method,i can get the no of rows in the record set?

Does anyone help me that by which method,i can get the no of rows in the record set?
now i use next() to check whether the next record is available or not?

under Practice Exercise #1 heading :
there is a statement.
"Now, the COUNT function does not need to retrieve all of the fields from the table (ie: employee_number, employee_name, and salary), but rather whenever the condition is met, it will retrieve the numeric value of 1. Thus, increasing the performance of the SQL statement."And have you ever tried it? Or do you simply blindly believe everything you read? And what sort of "authority" is "tech on the net"?
P.S. A quick test on Oracle (and you must do each query at least twice throwing away the first result, as Oracle always caches things which will have an effect, and averaging the remaining attempts).
count(*) -- 1 min 17 secs for 35,311,978 rows
count(1) -- 1 min 19 secs for 35,311,978 rows
Edit: And the table has 46 columns.

How to get the last inserted record from a table ?

:-) Hiee E'body
I work on Oracle 8i and need to get the last
record inserted in a table.
I have tried using rownum and rowid pseudo-columns
but that doesn't work.
Can you please help me out ?
:-) Have a nice time

I'm not sure about 8i features.
I assume here that you don't have 'Date-Time' stamp columns on the table which is the easiest way to determine the last inserted row in the table.
If not try the following :-
select address, piece, SQL_TEXT
from V$SQLTEXT
where upper(sql_text) like '%INSERT INTO TABLE_NAME%'
Substiute the TABLE_NAME with the name of the actual table.
Have fun.
