Alternative for select count('x') or count(*)

Hi Gurus,
I need to use select count(*) multiple times in a SP before and after deletion of rows from multiple tables. As this is an expensive method, do we have some alternative for Count(*), like selecting something from a system table or view instead?

Hi
You can know the number of rows affected by the DELETE statement in PL/SQL (if you are using PL/SQL) using sql%rowcount. So you don't really need to count the rows again after the delete took place...
If you are deleting the same rows as selected by the second count condition (older than a particular date), in fact you only need to count rows once for each table.

Check this query. It should give you desired results....Are you sure about that? Does TOP 1 mean "whatever happens to be the first row fetched"?

Alternative for selecting ISF file in FM12 Webhelp publishing

Hi
I am currently evaluating TCS5/ FM12 as an upgrade from TCS4/ FM11.
In TCS 4, I could create an ISF file that contains my FM-RH style mapping and use that file in FM to publish the WebHelp. Now in FM12, I don't see the option to assign the ISF file. Instead, I need to start all over, first pull up the CSS file that contains the custom styles I added in RH, and then create a STS file which stores my style mapping.
Is there any other way out? I have about 70+ styles, mapping and testing them again would be a crazy task!
Thanks in advance.
Sreekanth

Sreekanth,
Perhaps you can create a custom HTML template [AFAIK, that's essentially what the RH master page is - I don't know if you can export this from RH, as I don' use it much] and use the option to import an HTML template:
Addendum: see Adobe FrameMaker 12 * Using HTML page templates

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(*) for each row of a table

Hello All,
Following query gives a statistics for each user (how many items he owns, home many tickets authored, how many objects he is subscribed to etc...)
select auser.userid,
(select count(*) from item where owner like '%' || auser.id || '%') ITEM_OWNER_CNT,
(select count(*) from tkt where originator = auser.id) TKT_ORIGINATE_CNT,
(select count(*) from tkt where assigned_to = auser.id) TKT_QA_CNT,
(select count(*) from tkt where create_user = auser.id) TKT_AUTHOR_CNT,
(select count(*) from subscriptions where subscriber_id = auser.id) SUBSCRIPTION_CNT
from
user auser
I was not happy with the performance of this query, so I tried the same using group by. The performance was even worse.
Is there any other option for me to try? Please advice.
Thanks,
Sathish

Hi, Sathish,
As SBH said, a lot depends on your data. Please post some sample data (CREATE TABLE adn INSERT statemetns) for all tables, and the results you want from that data. Describe and give examples of any relationships that are not one-to-one..
You probably want to do joings, like SBH suggested, rather than scalar sub-queries.
The connection between the auser and item tables
(select count(*) from item where owner like '%' || auser.id || '%') ITEM_OWNER_CNT,is very suspicious. Perhaps the item table is poorly designed, and the query would be faster if that table were changed. Is changing the design of the item table an option?
You should be able to get all the information from the tkt table in one pass. It looks like you need to unpivot the data, so instead of one row per ticket (with 3 different people connected to it), there are 3 rows per ticket, each with only 1 person referenced. This is not necessarily a bad table design. Unpivoting, even more than most other things, depends on your database version, so you'll have to tell what version of Oracle you're using.

Count (*) for select stmt take more time than execute a that sql stmt

HI
count (*) for select stmt take more time than execute a that sql stmt
executing particular select stmt take 2.47 mins but select stmt is using the /*+parallel*/ (sql optimer) in that sql command for faster execute .
but if i tried to find out total number of rows in that query it takes more time ..
almost 2.30 hrs still running to find count(col)
please help me to get count of row faster.
thanks in advance...

thanks in advance...That may be because your client is displaying only the first few records when you are running the "SELECT *". But when you run "COUNT(*)", the whole records has to be counted.
As already mentined please read teh FAQ to post tuning questions.

Better and faster alternative for count(*)

I want to check whether empno=1234 exists in emp table
Currently I am using in proc
      select count(*) into cnt from emp
                     where empno=1234
    if cnt>1 then exists otherwise no exists.
    Is there any better way to do the same.?

Create dynamic report or query for piece count

Hi abaper's
This is a very straight forward requirement. so please give me code
First you have to get the corresponding plant from table T320 for the given warehouse numbers in the selection screen.
1. Get the sum of order qty of sales orders from the sales order tables for the given warehouse(Plant), distribution channel and the give date range.
2. Get the confirmed transfer orders qty from the TO master table where TO confirmation date is in the given date range and WH number.
3. Get the total PGIed qty from the delivery master table where PGI'ed date in the given date range, shipping point is in the corresponding plant of the WH and for the given distribution channel.
As you are going to use the major tables please try to write the select commands effectively to avoid further performance issues.

How to improve the performance fo this code.....this very urgent.

Performance issue when using select count on large tables

Hello Experts,
I have a requirement where i need to get count of data from a database table.Later on i need to display the count in ALV format.
As per my requirement, I have to use this select count inside a nested loops.
Below is the count snippet:
LOOP at systems assigning <fs_sc_systems>.
LOOP at date assigning <fs_sc_date>.
SELECT COUNT( DISTINCT crmd_orderadm_i~header )
 FROM crmd_orderadm_i
 INNER JOIN bbp_pdigp
 ON crmd_orderadm_iclient EQ bbp_pdigpclient "MANDT is referred as client
 AND crmd_orderadm_iguid EQ bbp_pdigpguid
 INTO w_sc_count
WHERE crmd_orderadm_i~created_at BETWEEN <fs_sc_date>-start_timestamp
 AND <fs_sc_date>-end_timestamp
 AND bbp_pdigp~zz_scsys EQ <fs_sc_systems>-sys_name.
endloop.
endloop.
In the above code snippet,
<fs_sc_systems>-sys_name is having the system name,
<fs_sc_date>-start_timestamp is having the start date of month
and <fs_sc_date>-end_timestamp is the end date of month.
Also the data in tables crmd_orderadm_i and bbp_pdigp is very large and it increases every day.
Now,the above select query is taking a lot of time to give the count due to which i am facing performance issues.
Can any one pls help me out to optimize this code.
Thanks,
Suman

Hi Choudhary Suman ,
Try this:
SELECT crmd_orderadm_i~header
INTO it_header " interna table
FROM crmd_orderadm_i
INNER JOIN bbp_pdigp
 ON crmd_orderadm_iclient EQ bbp_pdigpclient
 AND crmd_orderadm_iguid EQ bbp_pdigpguid
 FOR ALL ENTRIES IN date
WHERE crmd_orderadm_i~created_at BETWEEN date-start_timestamp
 AND date-end_timestamp
 AND bbp_pdigp~zz_scsys EQ date-sys_name.
 SORT it_header BY header.
 DELETE ADJACENT DUPLICATES FROM it_header
 COMPARING header.
 describe table it_header lines v_lines.
Hope this information is help to you.
Regards,
José

Select count from large fact tables with bitmap indexes on them

Hi..
I have several large fact tables with bitmap indexes on them, and when I do a select count from these tables, I get a different result than when I do a select count, column one from the table, group by column one. I don't have any null values in these columns. Is there a patch or a one-off that can rectify this.
Thx

You may have corruption in the index if the queries ...
Select /*+ full(t) */ count(*) from my_table t
... and ...
Select /*+ index_combine(t my_index) */ count(*) from my_table t;
... give different results.
Look at metalink for patches, and in the meantime drop-and-recreate the indexes or make them unusable then rebuild them.

That 418 seconds - not the hours you reported earlier. Is it possible that your connection to the database broke ?
On a typical system, by the way, you can usually turn one direct read for tablescan into 1MB, so your scan seems to have covered about 59 GB, which seems to be in the right sort of ballpark for 130M rows.
we have another query and when we test the query execution using v$sql, is_bind_sensitive =N, how to make is_bind_sensitive=Y all the time.. There is a hint /*+ bind_aware */ - I'd have to check whether or not it's documented at present. It might help.
I would be interested in hearing why you think the hint should be bind sensitive when the optimizer doesn't.

SELECT COUNT( ) gives warning in ECC6.0.

Hi,
The following query is giving syntax error in ECC6.0, where as it worked absolutely fine in 3.1i server.
SELECT COUNT( OBOX_CNTNO ) FROM ZT2OB
 INTO W_COUNT
 WHERE SUPPL_CD = W_SUPPL_CD
 AND INVC_NO = W_INVC_NO
 AND INVC_LN_NO = T_SCR_ITEMS-INVC_LN_NO.
Error: "COUNT( OBOX_CNTNO )" is only valid in the extended form "COUNT( DIS

The query seems obsolete in ECC6.0. Can anybody help me to give valid query for this in ECC6.0?

Hi,
Count functionality is to be used along with Distinct functionality.

Sub-Select Count query breaking TOAD

When I try to export it, or scroll down to view > 500 rows, TOAD crashes.
I know this isn't a TOAD forum, but I think that this is probably an issue with my no doubt rubbish SQL.
If I take out this sub-select, then the problem doesn't happen:

          FROM po.po_headers_all pha2
             , po.po_lines_all pla
         WHERE pha2.po_header_id = pla.po_header_id
           AND pla.contract_id = pha.po_header_id) po_countHowever, I can't work out a better way of getting the data I need.
The sub-select counts POs which have been raised where the contractID on the PO line is the same as the PO Header ID from the main query.
Any advice please, on what I could do to sort this out would be much appreciated.
Thanks!

Hi,
It looks like you can replace both scalar sub-queries with a join, like this:
WITH     header_lines_summary     AS
     SELECT    pla.contract_id
          ,       COUNT (DISTINCT pha2.po_header_id)     AS po_count
          ,       MAX (pha2.creation_date)          AS latest_cpa_po
          FROM        po.po_headers_all pha2
             ,        po.po_lines_all   pla
         WHERE        pha2.po_header_id = pla.po_header_id
      GROUP BY       pla.contract_id
)                                        -- Everything up to this line is new
SELECT pha.segment1
     , pha.type_lookup_code
     , hls.po_count                              -- Changed
     , hls.latest_cpa_po                         -- Changed
FROM po.po_headers_all     pha
     , po.po_vendors           pv
     , po.po_vendor_sites_all      pvsa
     , header_lines_summary     hls                    -- New
WHERE pha.vendor_id          = pv.vendor_id
   AND pha.vendor_site_id     = pvsa.vendor_site_id
   AND pha.po_header_id          = hls.contract_id (+)          -- New
--   AND pv.VENDOR_NAME      LIKE 'H%'
   AND pha.vendor_id           = 98
   AND pha.type_lookup_code      = 'CONTRACT'
   AND pha.org_id           IN (7041, 7042);Aside from the sub-query (which is entirely new), the query above is just what you posted, with 2 lines changed and 2 lines added, as marked.
This should be more efficient, but I don't know for certain that it will solve the Toad problem.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
It never hurts to say what version of Oracle you're using.

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

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.

Cool
That now makes sense

Alternative for select count('x') or count(*)
