ONE ROW COUNT

Hi
wat is the1 ROW COUNT key figure in reporting

Do you want to use the count in a query or just for informational purpose? If you want to use it in the query then check out this How-To paper:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/7e58e690-0201-0010-fd85-a2f29a41c7af
If you want the count for informational purpose then you can just do a listcube and check the "Output Number of Hits" this will get you the count according to your selection criteria in list cube.
If you want the total count for the cube you can look at the database level via transaction se16 and look at the E and F table for the particular Infocube.

Hi rhiesnand,
right now you add 2 new rows to your array.
The solution is to concatenate both row parts to one bigger 1D array before adding that array as new row to your 2D array!

Counting consecutive numbers into one row

Hello everyone,
I have recently discovered that we can use Max ( Decode ()) function of Oracle to pivot the results of a table. I have executed this just fine. However, pivoting a table is just one part of the solution that I need. The pivoting function results to something like this:
01,02,03,05,06,07,08,09,10,11,12,13,14,16,17,20,21,23,25What I actually need is something like this:
1-17, 20-21,23,25I really don't know how to start solving this but so far I have the below query:
SELECT DISTINCT
     MAX(DECODE(wldw.wafernumber,'01', '01'))
      || MAX(DECODE(wldw.wafernumber,'02', ',02'))
      || MAX(DECODE(wldw.wafernumber,'03', ',03'))
      || MAX(DECODE(wldw.wafernumber,'04', ',04'))
      || MAX(DECODE(wldw.wafernumber,'05', ',05'))
      || MAX(DECODE(wldw.wafernumber,'06', ',06'))
      || MAX(DECODE(wldw.wafernumber,'07', ',07'))

First, you need some way of grouping consecutive rows together (1-17 in one group, 20-21 in anoter, 23 as a group all by itself, and so on).
Then you need GROUP BY to get infmation about each goup, such as the smallest and largest number in the group.
Finally, you need to combine all that information into one big string. This is actually an example of String Aggregation , rather than pivoting. The two are closely related. Pivot means you're taking 1 column on multiple rows, and putting them into multiple columns on one row. String Aggregation is taking 1 column on multple row, and concatenating all their contents into one big string column.
Here's one way to do it:
WITH     got_group_id     AS
     SELECT     wafernumber
     ,     ROW_NUMBER () OVER (ORDER BY wafernumber)
                  - wafernumber          AS group_id
     FROM     wldw
,     got_group_info     AS
     SELECT       TO_CHAR (MIN (wafernumber))
            || CASE
                     WHEN COUNT (*) > 1
                THEN '-' || TO_CHAR (MAX (wafernumber))
                 END             AS group_label
     ,       ROW_NUMBER () OVER (ORDER BY MIN (wafernumber))
                         AS group_num
     FROM      got_group_id
     GROUP BY group_id
SELECT SUBSTR ( SYS_CONNECT_BY_PATH (group_label, ',')
            , 2
            )     AS txt
FROM    got_group_info
WHERE     CONNECT_BY_ISLEAF     = 1
START WITH     group_num      = 1
CONNECT BY     group_num     = PRIOR group_num + 1
     AND     prior sys_guid () is not null
;I find the first part of this query to be the trickiest. I used the Fixd Difference technique to assign a common group_id to consecutive rows. See {message:id=9953384} and/or {message:id=9957164} foran explantaion of the Fixed Difference technique.
Next, in sub-query got_group_info, I used aggregate functions to produce a group_label, such as '1-17', and to assign consecutive numbers to each group. This is also a little tricy, because it involves nesting an aggregate function (MIN in this case) inside an analytc function (ROW_NUMBER).
Finally, I used SYS_CONNECT_BY_PATH to do the string aggregation.
Output:
TXT
1-17,20-21,23,25Whenever you have a question, please post CREATE TABLE and INSERT statements for some sample data. For example:
CREATE TABLE     wldw
(       wafernumber     NUMBER (3)     PRIMARY KEY
INSERT INTO wldw (wafernumber) VALUES ( 1);
INSERT INTO wldw (wafernumber) VALUES ( 2);
INSERT INTO wldw (wafernumber) VALUES ( 3);
INSERT INTO wldw (wafernumber) VALUES ( 4);
INSERT INTO wldw (wafernumber) VALUES ( 5);
INSERT INTO wldw (wafernumber) VALUES ( 6);
INSERT INTO wldw (wafernumber) VALUES ( 7);
INSERT INTO wldw (wafernumber) VALUES ( 8);
INSERT INTO wldw (wafernumber) VALUES ( 9);
INSERT INTO wldw (wafernumber) VALUES (10);
INSERT INTO wldw (wafernumber) VALUES (11);
INSERT INTO wldw (wafernumber) VALUES (12);
INSERT INTO wldw (wafernumber) VALUES (13);
INSERT INTO wldw (wafernumber) VALUES (14);
INSERT INTO wldw (wafernumber) VALUES (15);
INSERT INTO wldw (wafernumber) VALUES (16);
INSERT INTO wldw (wafernumber) VALUES (17);
INSERT INTO wldw (wafernumber) VALUES (20);
INSERT INTO wldw (wafernumber) VALUES (21);
INSERT INTO wldw (wafernumber) VALUES (23);
INSERT INTO wldw (wafernumber) VALUES (25);I realize that your table (and your query) are a lot more complicated, but it looks like you can show the part you don't already understand using just this one table with this one column.
Also, whenever you have a question, say which version oif Oracle you'e using (e.g., 11.2.0.2.0).
The query above should work in Oracle 10.1 and up. I got the wong results in the main query in Oracle 10.2, however. (Oracle 10.2 has a lot of bugs related to CONNECT BY.) It worked fine in version 11.1.
If you're using Oracle 11.2, you'll want to use LISTAGG, not SYS_CONNECT_BY_PATH, to do the string aggregation.
For more about string aggregation in various versions of Oracle, see this Oracle Base page.

One row expected but not counted with resultSet.next()

Hi all, I am using the following method to check an entry in my database. The problem is that the while(rs.next()) loop is not entered and therefore not counting the rows within the resultSet. This only occurs when one row is retrieved from the db. The query executed definitely works.
 private boolean enteredInDaily(String date, String chan)
 int rowCnt = 0;
 String query = "SELECT id FROM daily WHERE " +
 "name = '" + name+ "' AND " +
 "start_date <= '" + date + "' AND " +
 "finish_date >= '" + date + "'";
 try {
 Class.forName("org.gjt.mm.mysql.Driver");
 Connection dbCon = DriverManager.getConnection("jdbc:mysql://localhost/dbname?user=&password=");
 Statement stmt = dbCon.createStatement();
 ResultSet rs = stmt.executeQuery(query);
 while(rs.next()) {
 //this loop not entered
 System.out.println(rs.getInt("id"));
 rowCnt++;
 catch(ClassNotFoundException ex) {
 System.out.println(ex); }
 catch(SQLException ex) {
 System.out.println(ex); }
 System.out.println("rowCnt = " + query);
 if (rowCnt == 0)
 return false;
 else
 return true;
 }Can anyone shed any light on this problem??? Thanks.

How very silly of me!! I was connecting to the real database and not my test db. Sorry to waste a post.

If you are OK with displaying comma separated list or column data you could:

3           select ename,
4                   row_number() over(order by 1) rn,
5                   count(*) over() cnt
6             from emp
7          )
8    where rn = cnt
9    start with rn = 1
10    connect by rn = prior rn + 1
11 /
ENAME_LIST
SMITH,ALLEN,WARD,JONES,MARTIN,BLAKE,MILLER,SCOTT,KING,TURNER,ADAMS,JAMES,FORD,CLARK
SQL> To display as separate columns you would need to either know number of rows:
SQL> select min(case rn when 1 then ename else null end) ename1,
2          min(case rn when 2 then ename else null end) ename2,
3          min(case rn when 3 then ename else null end) ename3,
4          min(case rn when 4 then ename else null end) ename4,
5          min(case rn when 5 then ename else null end) ename5,
6          min(case rn when 6 then ename else null end) ename6,
7          min(case rn when 7 then ename else null end) ename7,

How to add the Row count(number of rows in table) in the table header?

Hi,
I'm having a table. This table is viewed when i click on a search button.
On the table header it should dynamically display the number of rows in the table, i.e., the row count.
How to do this? could any one explain me with the detailed procedure to achieve this.
Thanks & Regards,
Suresh

If you want to show a localized text in the table header, you should use the Message Pool to create a (parameterized) message "tableHeaderText" like "There are table entries".
Next, create a context attribute "tableHeaderText" of type "string" and bind the "text" property of the table header Caption UI element to this attribute.
Whenever the table data has changed (e.g. at the end of the supply function for the table's data source node), update the header text:
int numRows = wdContext.node<TableDataSourceNode>().size();
String text = wdComponentAPI.getTextAccessor().getText
IMessage<ComponentName>.TABLE_HEADER_TEXT,
new Object[] { String.valueOf(numRows) }
wdContext.currentContextElement().setTableHeaderText(text);
Maybe you want to provide a separate message for the case that there are no entries.
Alternatively, you can make the attribute calculated and return the header text in the attribute getter.

Can any one give me clue ,how to find out which sub query returns more than one row in the following query .This is why smaller, simpler queries are easier to work with than huge ones - when something like this goes wrong smaller queries are much eaiser to debug.

Ganesh is right - you will have to dissect the big query bit by bit until you find the offending subquery. If there is another way I would like to find out about it too.
The easiest way to do this is probably to use block comments to isolate parts of the query bit by bit until you find the offending part. If you carefully examine the subqueries you might be able to figure out which one is returning multiple rows without commenting everything
Good luck!

Java.sql.SQLException: while calculating row count: Unexpected exception :

I am working with JDBC that is connected to MS Access 2003 file.
I wrote and tested in MS Access following query and all it is working well. If I write this query and execute it is working well.
pstm = DBConnect.prepareStatement(
"SELECT Parameter.Name, Parameter.id FROM " +
"(ParameterGroupMember INNER JOIN ApplicationReadsParameter ON " +
"ParameterGroupMember.Member_Parameter_id = ApplicationReadsParameter.Parameter_id)" +
"INNER JOIN Parameter ON ApplicationReadsParameter.Parameter_id = Parameter.id " +
"WHERE (ParameterGroupMember.Group_Parameter_id=40) " +
"UNION ALL SELECT Parameter.Name, Parameter.id FROM " +
"Parameter INNER JOIN ApplicationReadsParameter ON " +
"ApplicationReadsParameter.Parameter_id=Parameter.id WHERE (Parameter.id=40); ");
rs = pstm.executeQuery();
When I use code, that sets parameters in the statement it is firing following exception

Further I found that the problem is with the setting of the second parameter in the statement. Is there different way how to set the second parameter if union is used?
Thanks and regards,

Use code tags when you post code.

"(ParameterGroupMember INNER JOIN ApplicationReadsParameter ON " +I STRONGLY suggest that rather than putting spaces at the end of each part put it at the beginning. It makes it much easier to get it right.
I also suggest formatting the code. There are various ways.
        // Wrong
        String sql = "select x, y z "
                         + "from table1 t1, idtable idt"
                         + "where t1.tim=idt.tim "
                         + "and t1.book = idt.book";
        // Right (spaces) - one way to format
        String sql = "select"
                         + "         x, y z"
                         + " from table1 t1, idtable idt"
                         + " where"
                         + "          t1.tim=idt.tim"
                         + "          and t1.book = idt.book";Your code is in fact missing a space. No idea if that is a problem or not.
Remove the semicolon from the end.
PRINT the sql before you use it, copy/paste and use that string in MS Access (replace the ?) to see if it work.
Further I found that the problem is with the setting of the second parameter in the statement. Is there different way how to set the second parameter if union is used?The MS Access ODBC driver isn't really great for actually reporting errors correctly. So usually any error means something is wrong and it is up to you to figure out the exact problem.

Oracle database link to MySQL select only one row

Hello,
I have created a connection from the Oracle batabase 11.2 to a MySQL database via database link. The following statement shows, that 35 rows are in the mySQL table:
SQL> select count(*) from "main_pages"@MOREWEB;
COUNT(*)
 35
But a normal select statement only return 1 row.
SQL> select "subject" from "main_pages"@MOREWEB;
subject

I am using the mysql-connector-odbc-3.51.30-winx64 driver. A newer version cann't be installed because on Windows Server 2008 R2 I get an error with an missing dll-file. The DataDirect-ODBC-driver is not possible, because we like to use the free MySQL-database an DataDirect only support the enterprise edition.
I also have tried to limit the HS_OPEN_CURSORS or dont limit the HS_FDS_FETCH_ROWS, but there is no difference in the result. I always get only one row.

Bianca,
If you log directly into MySQL and issue the same query (select "subject" from "main_pages";) what data is returned?
I looks to me that you count is the number of rows in the entire table "main_pages"
while you select is for the data in the "subject" column only.
This seems to indicate that you have just one row in that subject column.
Regards,
Matt
WHAATT?
What do you mean by "just one row in that subject column"?
That makes no sense at all. A row is a row. A column is a part of a row. All rows have all columns, though not all columns of all rows will necessarily have an assigned value. Lacking a WHERE clause to filter rows, any SELECT should return all rows.

Select Single * and Select upto one row

Hi all,
Can anybody tell me what is difference between Select single * and select upto one row?
And which one is better?
Thanks in advance.......

According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.
select single is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.
The best way to find out is through sql trace or runtime analysis.
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
Mainly: to read data from
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.
Mainly: to check if entries exist.
Select Single is the best one compared to UPto one rows.
Select Single will get the first record from the table which satisfies the given condition.So it will interact once with the database.
UTO 1 rows will get the list of the records for the given match and iwll show the first record from the list.So it will take time to get the record.
SELECT SINGLE VBELN from VBAK
where MATNR = '1M20'.
---Thjis will get the first matched record and will display the record
SELECT VBELN from VBAK
where MATNR = '1M20' upto 1 rows.
---Thjis will get the list of matched records and will display the first record
The Major difference between Select Single and Select UPTO 1 rows is The Usage Of Buffer for each.
Select Single will search for all the satisfied data and bring all that data into Buffer and later it will give to that data to the program.
Select UPTO 1 Rows will end the search after getting the 1st satisfied record and gives that record to the program.
Thus Select Single will take much processing time when compare with Select UPTO 1 rows.

The condition would fire even if there were no rows returning.
I pasted the condition code into SQL Developer connected to the DEV (10.2.0.4.0) environment and it returned no rows.
To solve the problem, I removed the MAX.
You can test this using this code if you have access to the two versions... select MAX(1)
      , sysdate
      , 'Gus'
from dual
where 1 = 2
group by sysdate, 2Now I know the MAX isn't required in the condition as I'm just trying to find out if any rows exist, but it was there as I copied the code in... I was just wondering why this happened between 10.2.0.2.0 and 10.2.0.4.0?
Gus..

Hi Gus,
try to execute
select count(*) from dual where exists (select MAX(1)
      , sysdate
      , 'Gus'
from dual
where 1 = 2
group by sysdate, 2)in SQL Developer. The above statement is generated by APEX for an "Exists (SQL query retruns at least one row)". Can't test it, because I don't have a 10.2.0.4.0 at hand.
Does SQL Developer now show the same behavior?

Cursor ORDER BY Clause Changing Row Count In BULK COLLECT ... FOR LOOP?

Oracle 10g Enterprise Edition Release 10.2.0.4.0 running on Windows Server 2003
Oracle Client 10.2.0.2.0 running on Windows 2000
I have some PL/SQL code that's intended to update a column in a table based on a lookup from another table. I started out by testing it with the UPDATE statement commented out, just visually inspecting the DBMS_OUTPUT results to see if it was sane. During this testing I added/changed the cursor ORDER BY clause to make it easier to read the output, and saw some strange results. I've run the code 3 times with:
1. no ORDER BY clause
2. ORDER BY with two columns (neither indexed)
3. ORDER BY with one column (not indexed)
and get three different "rows updated" counts - in fact, when using the ORDER BY clauses it appears that the code is processing more rows than without either ORDER BY clause. I'm wondering why adding / changing an ORDER BY <non-indexed column> clause in a cursor would affect the row count?
The code structure is:
TYPE my_Table_t IS TABLE OF table1%ROWTYPE ;
my_Table my_Table_t ;
CURSOR my_Cursor IS SELECT * FROM table1 ; -- initial case - no ORDER BY clause
-- ORDER BY table1.column1, table1.column2 ; -- neither column indexed
-- ORDER BY table1.column2 ; -- column not indexed
my_Loop_Count NUMBER := 0 ;
OPEN my_Cursor ;
LOOP
FETCH my_Cursor BULK COLLECT INTO my_Table LIMIT 100 ;
EXIT WHEN my_Table.COUNT = 0 ;
FOR i IN 1..my_Table.COUNT LOOP
my_New_Value := <call a pkg.funct to retrieve expected value from another table> ;
EXIT WHEN my_New_Value IS NULL ;
EXIT WHEN my_New_Value = <an undesirable value> ;
IF my_New_Value <> my_Table(i).column3 THEN
DBMS_OUTPUT.PUT_LINE( 'Changing ' || my_Table(i).column3 || ' to ' || my_New_Value ) ;
UPDATE table1 SET column3 = my_New_Value WHERE column_pk = my_Table(i).column_pk ;
my_Loop_Count := my_Loop_Count + 1 ;
END IF ;
END LOOP ;
COMMIT ;
END LOOP ;
CLOSE my_Cursor ;
DBMS_OUTPUT.PUT_LINE( 'Processed ' || my_Loop_Count || ' Rows ' ) ;

Hello (and welcome),
Your handling the inner cursor exit control is suspect, which will result in (seemingly) erratic record counts.
Instead of:
LOOP
FETCH my_Cursor BULK COLLECT INTO my_Table LIMIT 100 ;
EXIT WHEN my_Table.COUNT = 0 ;
FOR i IN 1..my_Table.COUNT LOOP
my_New_Value := <call a pkg.funct to retrieve expected value from another table> ;
EXIT WHEN my_New_Value IS NULL ;
EXIT WHEN my_New_Value = <an undesirable value> ;
IF my_New_Value my_Table(i).column3 THEN
DBMS_OUTPUT.PUT_LINE( 'Changing ' || my_Table(i).column3 || ' to ' || my_New_Value ) ;
UPDATE table1 SET column3 = my_New_Value WHERE column_pk = my_Table(i).column_pk ;
my_Loop_Count := my_Loop_Count + 1 ;
END IF ;
END LOOP ;
COMMIT ;
END LOOP ;Try this:
LOOP
FETCH my_Cursor BULK COLLECT INTO my_Table LIMIT 100 ;
FOR i IN 1..my_Table.COUNT LOOP
my_New_Value := <call a pkg.funct to retrieve expected value from another table> ;
EXIT WHEN my_New_Value IS NULL ;
EXIT WHEN my_New_Value = <an undesirable value> ;
IF my_New_Value my_Table(i).column3 THEN
DBMS_OUTPUT.PUT_LINE( 'Changing ' || my_Table(i).column3 || ' to ' || my_New_Value ) ;
UPDATE table1 SET column3 = my_New_Value WHERE column_pk = my_Table(i).column_pk ;
my_Loop_Count := my_Loop_Count + 1 ;
END IF ;
EXIT WHEN my_Cursor%NOTFOUND;
END LOOP ;
END LOOP ;
COMMIT ;Which also takes the COMMIT outside of the LOOP -- try to never have a COMMIT inside of any LOOP.
Additionally, not too sure about these:
my_New_Value := <call a pkg.funct to retrieve expected value from another table> ;
EXIT WHEN my_New_Value IS NULL ;
EXIT WHEN my_New_Value = <an undesirable value> ;Any one of those EXITs will bypass your my_Loop_Count increment.

Had the cursor not found in the wrong place, now corrected.

One column one row w/ separator to be hierarchical columns

Dear Gurus,
I want to present the "+one column/one row data+"

JDeveloper F:Id better using an sql rather than pl/sql.
regards,

I think you'd struggle to do this in SQL alone, unless you use some fancy MODEL clause or Michaels can come up with some nifty XML solution. I would probably go with some PL/SQL as a pipelined function...
