Select count(*) returns double?

I have executed a 'select count(*) from ...' statement through ODBC against Oracle9i and I am very supprised that the returned ODBC type is a 'double' and not an 'int' (or a 'numeric').
Is this really correct?

Did you ever get a response or figure this out?
My problem is fairly simliar, but specific to an 11.1.0.7 and onward release of the Oracle Client.
Current C++ Application using ODBC API calling Oracle Client 10g (all versions), 11gR1 (v11.1.0.6) returns a LONG (4-byte integer) for "SELECT COUNT(*) from tablename"
Change Oracle client to 11gR1 (v11.1.0.7) or higher (11.2.x.y etc) and that same statement returns a DOUBLE (8-byte floating value equivalent to oracle NUMBER data type).
Since the backend DB is the same version, there must be a client side setting (I presume) that has changed the default behaviour of this Aggregate SQL function to return a double rather than a long. I'm hoping to find such a setting that I can either set programmatically through an ODBC API call, or in the Oracle Client configuration itself.
I even tried using SQL CAST to make it an INT SELECT CAST(COUNT(*) AS INT) FROM tablename but that still returns a DOUBLE (8-byte floating NUMBER).
Note: given that I use ODBC, I've written alot of generic C++ code supporting the return value as LONG, as that is how it's been for 10 years via ODBC. I'd like to maintain that if possible without having to write ORACLE specific code within my applications.

"select count(*)" and "select single *" returns different result

Good day!
product version SAP ECC 6.0
oracle10
data transfers from external oracle db into customer tables using direct oracle db link
sometimes I get case with different results from 2 statements
*mytable has 10 rows
*1st statement
data: cnt type I value 0.
select count( * ) into cnt from mytable WHERE myfield_0 = 123 and myfield_1 = '123'.
*cnt returns 10 - correct
*2nd statement
select single * from mytable WHERE myfield_0 = 123 and myfield_1 = '123'.
*sy-dbcnt returns 0
*sy-subrc returns 4 - incorrect, 10 rows are "invisible"
but
1. se16 shows correct row number
2. I update just one row from "invisible" rows using se16 and 2nd statement returns correct result after that
can not understand why
thank you in advance.

Thank you, Vishal
but,
general problem is that
1. both statements have the same WHERE conditions
2. 1st return resultset with data (sy-dbcnt=10), 2nd return empty dataset, but must return 1 in sy-dbcnt
Yes, different meaning, you are right, but must 2nd must return 1, because of "select single *" construction, not 0.
Dataset to process is the same, WHERE conditions are equal...
I think the problem is that how ABAP interperets select count(*) and "select single *".
Maybe "select count (*)" scans only PK from index page(s)? and "select single *" scans data pages? and something is wrong with that?
I'm new in SAP and didn't find any SAP tool to trace dump of data and indexes pages with Native SQL.
se16 shows all records.
And why after simple manual update of just one record using se16 "select single *" returns 1?
I've just marked one row to update, didn't change any data, then pressed "save".

DIfferent # of rows return using select * & select count(*)

In debugging some code (OWB generated PL/SQL) I came across the situation where by a query with count(*) returns a value of 600 rows. The same where clause using select * reports only 300 rows selected. There are 600 rows to select.
Any ideas why the difference ???
The code:
SELECT *
FROM "STG_SYSTEM_CUSTOMER_V" "STG_SYSTEM_CUSTOMER_V",
DW_REPRESENTATIVE INGRP8
where "STG_SYSTEM_CUSTOMER_V"."PILLAR_STATE_CD" IN 'VIC'
AND "STG_SYSTEM_CUSTOMER_V"."BUS_PILLAR_CD" = 'IGA'
AND ( "STG_SYSTEM_CUSTOMER_V"."MN_COMP_CD" = "INGRP8"."MN_COMP_CD" (+) )
AND ( "STG_SYSTEM_CUSTOMER_V"."COUNTRY_CD" = "INGRP8"."COUNTRY_CD" (+) )
AND ( "STG_SYSTEM_CUSTOMER_V"."COMP_CD" = "INGRP8"."COMP_CD" (+) )
AND ( "STG_SYSTEM_CUSTOMER_V"."BUS_PILLAR_CD" = "INGRP8"."BUS_PILLAR_CD" (+) )

AND ( "STG_SYSTEM_CUSTOMER_V"."SUPP_DIVISION_CD" = "INGRP8"."DIVISION_CD" (+) )
AND ( "STG_SYSTEM_CUSTOMER_V"."ALM_REP_NUM" = "INGRP8"."REP_NUM" (+) )

You're sure that the only difference between the two statelents is that "*" is replaced with "count(*)"? Assuming there are no transactions going on simultaneously, that would be a bug. Have you installed the latest patchset to your database?

Select Count(*) from... returns zero, select * from... returns 4000 recs?

Hi,
I have an odd situation where "select count(*) from my_view where some_clause" returns 0, but the exact same query fetching the data (ie "select * from my_view where some_clause") works fine and fetches, correctly, 4000+ records.
I have tried dropping and recreating the view, and collecting DB stats again, but the problem persists.
I had a look at the explain plans and they are very different, but both the SQL statements work fine on a copy of the database taken with impdp.
Does anyone have any suggestions on what might be going on here ?
Any help would be appreciated, I've run out of ideas !

Maybe it's the bug that a function based index is present and gets incorrectly used in the select count(*) statement?
If that's not the case, then please show us more details, like the statement and both execution plans.

Select count(Key_Field) from table_name never returns

I am doing some scalability tests and am building a db w/table that will contain 400Million records. I am trying to see how far along I am in the process, and am experiencing this problem.
The select count(ID) never returns.
Does anyone have any suggestions for me as to how i might make it perform better? I am not too familiar with such large scale implementations, so any advice would be appreciated, and you can feel free to tell me the most basic info... (I do read docs, etc, but there might be a place I have not yet searched..)
The hardware is not an issue, at least for my testing, as it is as follows, and I see the IO on the arrays is busy, but not too busy, and that is to be expected, and we are neither CPU or RAM bound.
SUN E4800
12 CPUs
48GB RAM
2 T3 Arrays (fiber cards on different IO boards)
4 internal drives (2 on each IO board), not mirrored or RAIDed

This is always a troublesome type of query.
Are you trying to count the number of all rows in a table? You can try to ANALYZE the table, then from user_tables select the NUM_ROWS

"select count(*) from dba_jobs_running" takes 5 minutes to return

Hi,
I login as sys or system from sql*plus to run query "select count(*) from dba_jobs_running". This query takes about 5 minutes to run.
Querying other DBA_* views returns instantly, only this dba_jobs_running view is troubling.
I have 11 records in dba_jobs, and 18 records in v$lock as usual.
No error or warning in logfile, no trace file.
What's possibly wrong with the server?
Thanks,
Harry

Hi,
The following are the exact statements I used to create the trace file:
alter session set timed_statistics=true;
alter session set max_dump_file_size=unlimited;
alter session set events '10046 trace name context forever, level 12';
select count(*) from dba_jobs_running;
exit;
The content of the trace file is attached at the end.
If it is CPU bound, I have no activity on the db host. I am solely using it to analyze this problem.

'select count(*) from x' returns 5460 rows and 'Select * from x' returns 0 rows

As you can see in the next lines something is wrong in my Oracle (8.0.6 on Win NT 4.0 sp 6a) :

1 row selected.
V_TERRA_TE is a complex join of 5 Tables :

I think that some not reported error happens in the select * with some temporary space or similar but only the message '0 rows selected' is displayed (instead the real error)
Could somebody help me ?
Thanks in advance

Forcing the Join/sort to be made on Disk (not on memory) the problem not happens. This demostrate that ORACLE has a VERY IMPORTANT BUG : It returns 0 rows wich is false.
To force it to work on disk i use this parameters :
alter session set sort_area_size=0
alter session set hash_join_enabled=false
Note : probably is not the best combination or use of parameters, but using it the query works as espected.

How to run a select count(*) with multiple rows returned

Hi,
I have to run a select count(*) for different reports.
1) Select count(*) from table
where state = 'CA'
2) Select count(*) from table
where state = 'NY'
3) Select count(*) from table
where state = 'NV'
Instead of running this query again for 50 times, is there a way for me to just put it in one query and get multiple row returns? Thank you.

Select count(*) on sql statement returning zero when a matching row exists.

Our account has an ANSI C application that checks for the existence a row on an Oracle table(s) by using the following SQL:
int iCount = 0;
EXEC SQL
SELECT count(rownum) INTO :iCount
FROM sys.all_tab_columns
WHERE table_name IN
(SELECT table_name FROM
sys.all_synonyms
WHERE upper(synonym_name) = upper(:szDestTable))
AND upper(column_name) = upper(:szColumnName)
AND owner = 'DBAUSER';
The bind variables szDestTable and szColumnName are populated with values parsed from columns on another database table. This application is executed through out the day. Occasionally, the application will report a zero in the iCount when there should be a match. I have verified the szDestTable and szColumnName are populated with the correct values which would find a match and they are correct. To make matters even stranger, the application will parse the same input values and find a match (as it should). At some point during the day, and it can be at any time, the application will NOT find a match on the same file, same values. Every subsequent execution of this application will not find a match on the same values. Once the database is brought down and started up in the evening for its normal backups, the application will find a match again on the same values. This problem does not occur every day. I could be a week or a week and a half between incidents.
I printed the contents of the sqlca.sqqlerrm.sqlerrmc field to a log file. The sqlca.sqlerrm.sqlerrmc field reported an ORA-1405 bind variable was null when the iCount was reporting a zero. When I compiled this application, I set the Proc*C flag to UNSAFE_NULLS=yes since there are other bind variable in the application that can be NULL and that is ok.
The above SQL is compiled into the C application using the Proc*C compiler. It is compiled using the Oracle 11.2.0.2 libraries. The application is executed against an Oracle 11.2.0.2 database. The database and application are executed on an HP/Unix 11.31 platform.
This problem did not start occurring until our account went from Oracle 10.2 to Oracle 11.2. Recently, I have changed the SQL to perform a “SELECT COUNT(rownum)” instead of the “SELECT COUNT(*)”. I compiled the application and executed the new application with the SELECT COUNT(rownum) against the same database where the same application with the SELECT COUNT(*) was failing to find a row that actually existed. The application with the SELECT COUNT(rownum) found the matching row as it should have. The new application has been executing in production for about 10 days now without any problems against ten various Oracle 11.2 databases.
Why would SELECT COUNT(*) and SELECT COUNT(rownum) be any different?

Using / returning double

Hey peeps
after some guidance
ok, so my lecturer for programming is quite well known in the java world, although thats probs going to get shot down now :D he wrote bluej and the text book objects first. This week he set me an assignment and i have done all the base tasks and all the challenge tasks, but we get marked for comment considteny and layout of brackets etc to.
so one of the challenge tasks was to return an avergae playing time using double, is the correct way, the 100% correct way of doing this
    public double averageTrackLength()
        return (double) totalPlayingTime / tracksPlayed;
    }or does it need editing
thanks very much

ok, i think i worded it wrong, what i mean is, have i used the double function correctly, as in, to return a double value to you only need
public double averageTrackLength()
        return (double) totalPlayingTime / tracksPlayed;
    }becuase some people online from what i have read suggest this is how to do ti
public double divide(){
   return (double)x / (double)y;
}which is "correct"? :D
also, finally, sorry to get on all of your tits, i have a concern with my commenting, have i just over killed commenting :D

SSRS Report Returning Double Quote string from a Single Quote String

Hi, I'm getting weird thing in resultset from SSRS report when executed. When I pass parameter to a report, which passes String that has single quote value to a split function , it returns rows with double quote.
For example following string:
'N gage, Wash 'n Curl,Murray's, Don't-B-Bald
Returns:
''N gage, Wash ''n Curl,Murray''s, Don''t-B-Bald
through SSRS report.
Here is the split function Im using in a report.
CREATE Function [dbo].[fnSplit] (
@List varchar(8000),
@Delimiter char(1)
Returns @Temp1 Table (
ItemId int Identity(1, 1) NOT NULL PRIMARY KEY ,
Item varchar(8000) NULL
As
Begin
Declare @item varchar(4000),
@iPos int
Set @Delimiter = ISNULL(@Delimiter, ';' )
Set @List = RTrim(LTrim(@List))
-- check for final delimiter
If Right( @List, 1 ) <> @Delimiter -- append final delimiter
Select @List = @List + @Delimiter -- get position of first element
Select @iPos = Charindex( @Delimiter, @List, 1 )
While @iPos > 0
Begin
-- get item
Select @item = LTrim( RTrim( Substring( @List, 1, @iPos -1 ) ) )
If @@ERROR <> 0 Break -- remove item form list
Select @List = Substring( @List, @iPos + 1, Len(@List) - @iPos + 1 )
If @@ERROR <> 0 Break -- insert item
Insert @Temp1 Values( @item ) If @@ERROR <> 0 Break
-- get position pf next item
Select @iPos = Charindex( @Delimiter, @List, 1 )
If @@ERROR <> 0 Break
End
Return
End
FYI: I'm getting @List value from a table and passing it as a string to split function.
Any help would be appreciated!

Another user from TSQL forum posted this code which is returning the same resultset but when I execute both codes in SQL server it works and return single quote as expected.

Select * shows 1 record - select count(*) shows 2232 records

Using SQL 2008 R2 and SS Import Wizard
Imported Excel file into SQL Table. No errors reported during import.
Command: Select * From XLImport
returns 1 record
Command: Select Count(*) From XLImport
returns 2232
What could be causing this ??
Many thanks
MisterT99

I see what happened.
A previous command issued 'Set ROWCOUNT 1'
When I entered 'Set ROWCOUNT 0' That fixed the problem.
Thanks everyone for your comments.
MisterT99
Cool
That now makes sense

Select count into versus create table as in functions/procedures

I am working on a dynamic PL/SQL script that will count the number of records in a remote database
based on certain criteria and then if the number is "acceptable" will create a table in the connecting
database with those records.
My where clauses are supposed to be the same but I am presented with the problem, when I run the
first code ... select in to rowcount I get 122000 records, when I later do the create table as
with the same whereclause code, I get 77 records. So now I am attempting to validate that the two
where clauses are the same ... you'd think it would be obvious, but it's not.
My first operation does a select count(*) into rowcount with the where clause behind it.
The second operations creates a "sql command literal' that gets executed and returns the less value.
I build it like testscript := 'create table '||tablename ||'as select * from '||remotetablename||'@'||linkname;
testwhere := ' xxxxxxx'
then I do an execute immediate teststring ||' ' testwhere; which works but gives me 77 rows in the table.
Since I believe my where clause might be different, how can I run the first operation ... select count into rowcount
as a normal SQL statement in the script...
When I attempt to just run it I get -- PLS-00428: an into clause expected in this select statement......
I will provide the source code in my next posting. Working to get it moved to this system.. Once you see it you'll understand
why I don't think, it's the same, but I need a way to run them exactly as they are written to understand the different results.
so How can I make the select count (*) into rowcount from .... work just like a normal select

Here is first part of the procedure --- I get returned value of 122000 records ....
SELECT COUNT (*)
               INTO ROWCOUNT
               FROM A_K_A_D_TBL@FCA08_INGRES
               WHERE (( "a_" = '1' OR "a_" = '6' ) AND
                         ( "d_t" <> '3' OR "k_c_s" = 'Y' ) AND
                         "d_d" < DATECUTOFFDATE AND
                    "k_c_d" < DATECUTOFFDATE )OR
(( "a_" = 4 OR "a_" = 7 ) AND
                         ( "d_t" <> '3' OR
"k_c_s" = 'Y' OR
"r_t" = '0' OR
                    "r_t" = '2' OR
               "r_t" = '3' ) AND
                    "d_d" < DATECUTOFFDATE AND
                    "k_c_d" < DATECUTOFFDATE AND
                    "r_d" < DATECUTOFFDATE AND
                    "s_d" < DATECUTOFFDATE);
then I attempt to duplicate it for string literals.... when this runs ... I get only 77 records. So that makes me think that my strings are not
done properly.
So I want to try to run the first sql itself ... but then I get the errors about needing select into ..... etc..
               TESTWHERE := q'[WHERE (( "a_" = '1' OR "a_" = '6' ) AND ( "d_t" <> '3' OR "k_c_s" = 'Y' )]'||

SELECT COUNT(*) bug

I have a table named comments, with a column labeled book_id. In this column I have non-unique integer values (we'll say 2 rows contain the number 9)
import flash.events.*;
import flash.data.*
import fl.controls.ComboBox;
import flash.filesystem.File
//Open database-------------------------------------------------------------
var conn:SQLConnection = new SQLConnection();
conn.addEventListener(SQLEvent.OPEN, openHandler);
var dbFile:File = File.desktopDirectory.resolvePath("tarot.db");
conn.openAsync(dbFile);
//authorsCB.addEventListener(Event.CHANGE, loadBooks);
function openHandler(event:SQLEvent):void
var selectStmt:SQLStatement = new SQLStatement();
selectStmt.sqlConnection = conn;
// define the SQL text
selectStmt.text = "SELECT COUNT(*) FROM comments2 WHERE book_id = 9";
// register listeners for the result and failure (status) events
selectStmt.addEventListener(SQLEvent.RESULT, readResultHandler);
// execute the statement
selectStmt.execute();
// collect author data: author name and author ID. Populate authorCB with author name. authorID is used to match publications for the booksCB in the loadBooks() function
function readResultHandler(event:SQLEvent):void
var result:SQLResult = event.target.getResult();
var numResults:int = result.data.length;
for (var i:int = 0; i < numResults; i++)
var row:Object = result.data[i];
var bookID:uint = row.book_id;
var book:String = row.book;
var authorID:uint = row.author_id;
//combo box named authorsCB
authorsCB.addItem({label:bookID}); //assign table data to list box
addChild(authorsCB);
This code returns '0' even though my table contains two matching rows.
If I change my select statement to "SELECT * FROM comments WHERE book_id = 9", that works.
I'm trying to implement a query that will tell me if a particular value appears in this column. If that value appears in the table, then I want to run another query to extract the associated data.
Ultimately I'm loading combo box 1 with author names, and combo box 2 with book titles. I then want to run a 3rd query against my comments table. My comments table contains notes about the various books, but I don't have notes about every title, so I need to test if there are comments in the table before I try to extract those comments in order to avoid throwing an error.

Okay, I got it.
It's very difficult to find documentation on precisely HOW Adobe AIR implements some of the more obscure functions in SQLite. Even though SELECT COUNT(*) works in the Firefox SQLite Manager, it doesn't work the same way in AIR.
Through reviewing the COUNT(*) function in "Learning SQL" by O'Reilly, there was an example utilized in which you point to the column you want counted BEFORE the COUNT(*) function.
So, it becomes:
SELECT columnName, COUNT(*) someColumnName (optional) FROM someTable etc, etc.
After the FROM clause you could use a WHERE, or a GROUP BY.
Keep in mind that a GROUP clause runs after a WHERE clause.

Select Count(*) and actual row are differ: 136 rows vs 65k x 7 rows

Dear All,
Good morning. Need your advices. We had a view which is running and producing output to excel files. But recently after one of ours database migration, it were producing differ result: Select Count(*) and actual row are differ: 136 rows vs 65k x 7 rows. Error happen when we export out the row to csv file is produced 65000 rows x 7 worksheep. But when perform select count(*) from RTNEWWIP, result return: 136 rows.
Is there any way to trace below sql to find where go wrong?

query might be referring to different environment/schema as you are using database link to access some tables.
getting result/count from view means executing query which forms that view. try to run that query separately and see the output.
it may help you to debug

Select count(*) returns double?
