This is probably a simple question, but I am relatively new using SQL Queries.
I tried this which gives me half of what I need... SET STATISTICS IO ON
I also need my query to return the run time that it took to run my query.
Can someone help me please?
Thanks!

Hello,
I am creating a sales report that needs to display Sales statistics for a selected month grouped by Material. Also, it needs to display the same stats for the selected month of the previous year. Finally, it needs to display Year To Date Statistics for the current year and previous year up to and including the selected month.
Currently, I am using 3 queries to do this. The first one gets the statistics the current month grouped by material. The others sprocs get their corresponding information by me passing in the material number and the month and doing the appropriate sum. So, essentially, for a single line of the report, 3 queries are being done. The problem arises in that sometimes there may be as many as 300 materils displayed in a given month, which amounts to alot of db activity and a long delay loading the report.
Is there anyway to get this information in one swoop using some fancy aggregation?
Thanks,
Jake

Hi,
I have a table which has a few fields, one being "datetime_traded". I need to write a query which returns the row which has the closest time (down to second) given a date/time. I'm using MS SQL.
Here's what I have so far:
Code:
select * from TICK_D
where datetime_traded = (select min( abs(datediff(second,datetime_traded , Convert(datetime,'2005-05-30:09:31:09')) ) ) from TICK_D)
But I get an error - "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.".
Does anyone know how i could do this? Thanks a lot for any help!

SQL Server 2000 on Win2k
I'm fairly new to SQL Server and I'm just wondering if it's possible to Update Statistice for all indexes somehow? I'm looking at the Update Statistics command and it doesn't seem to be possible.
The situation we have is a reporting DB that basically has all it's tables truncated and remade every night by some DTS jobs that import from another datasource and change the data and build some denormalzed tables etc.
Some of the large Insert operations go from taking 8 mins to taking several hours sometimes and updating the stats seems to fix the problem for a while. So I'd like to make sure the optimizer has all the latest stats for all tables.
Any other advice would be appreciated.
Cheers.

View 2 Replies View RelatedIs an index based on a smallint (16 bit) really faster than an index based on an int (32 bit)
If so, how much...
Four tables
Table A: ID smallint (PK)
Text varchar(50)
Table B:ForeginID smallint (indexed - non unique)
Text varchar(50)
rowID int (PK)
Table C: ID int (PK)
Text varchar(50)
Table D:ForeginID int (indexed - non unique)
Text varchar(50)
rowID int (PK)
Table A and C contain identical data
Table B and D contain identical data
(Tables A and B were filled and then copied to Tables C and D)
Tables A/C are loaded with 64,000 records (-32,000 to 32,000)
Tables B/D are loaded with 6,400,000 records ForeginID loaded randomly with values between -32,000 and 32,000
The purpose of this test is to find out if identical queries joined on a smallint are actually faster than int based.
I ran 3 queries on each set:
- Full select
- Select on ID/Foregin ID
- Select on Table2 RowID joined to table 1
Here are the queries:
#1. Full select (smallint) - grouped to limit result set
-----------------------------------------------------------
SELECT intAID, COUNT(intBID)
FROM TESTintA
INNER JOIN TESTintB ON intAID = intBID
GROUP BY intAID
ORDER BY COUNT(intBID) desc
#2. Select on ID/Foregin ID (smallint)
------------------------------------------
SELECT intAID, intBID, strATXT, strBTXT
FROM TESTintA
INNER JOIN TESTintB ON intAID = intBID
WHERE intAID = 29120
#3. Select on Table2 RowID joined to table 1 (smallint)
------------------------------------------
SELECT intAID, intBID, strATXT, strBTXT
FROM TESTintA
INNER JOIN TESTintB ON intAID = intBID
WHERE intPK = 1050
#4. Full select (int) - grouped to limit result set
------------------------------------------
SELECT lngCID, COUNT(lngDID)
FROM TESTlngC
INNER JOIN TEXTlngD ON lngCID = lngDID
GROUP BY lngCID
ORDER BY COUNT(lngDID) desc
#5. Select on ID/Foregin ID (int)
------------------------------------------
SELECT lngCID, lngDID, strTXTC, strTXTD
FROM TESTlngC
INNER JOIN TEXTlngD ON lngCID = lngDID
WHERE lngCID = 29120
#6. Select on Table2 RowID joined to table 1 (int)
------------------------------------------
SELECT lngCID, lngDID, strTXTC, strTXTD
FROM TESTlngC
INNER JOIN TEXTlngD
ON lngCID = lngDID
WHERE intPK = 1050
Here are the results: (run multiple times to verify)
#1. Full select (smallint) - grouped to limit result set
-----------------------------------------------------------
(8 seconds) - before computing statistics on table
(13 seconds) - after computing statistics on table
#2. Select on ID/Foregin ID (smallint)
------------------------------------------
(0 seconds)
#3. Select on Table2 RowID joined to table 1 (smallint)
------------------------------------------
(0 seconds)
#4. Full select (int) - grouped to limit result set
------------------------------------------
(8 seconds) - before computing statistics on table
(7 seconds) - after computing statistics on table
#5. Select on ID/Foregin ID (int)
------------------------------------------
(0 seconds)
#6. Select on Table2 RowID joined to table 1 (int)
------------------------------------------
(0 seconds)
Conclusion: Not only is there a negligible difference in select performance, generating stats on the smallint actually makes it slower.
(perhaps there is some kind of conversion going on here behind the scenes?)

Recently we moved few of our databases from SQL 2000 to SQL 2005 (SP 2) using backup and restore. After the restore I did Reindex and update stats on the databases. Since then we have observed performance issues on SQL 2005 databases but this performance problem vanishes the moment we run (sp_updatestats). Is this a problem with SQL 2005 that we have to run sp_updatestats 2 times a days or 3 times a day. In SQL 2000 we ran it only Once a week and still we never had any performance issues. Is there any config change we need to do to fix this problem in SQL 2005?
Thanks !

VALUES (@COUNT, '12345678901234567890')
SET @COUNT = @COUNT + 1
END
I then look at Tables then statistics the statistics are empty so i fire update statistics and see 1000 rows in here.
I run again the insert script
DECLARE @COUNT INT
SET @COUNT = 1001
WHILE @COUNT <= 2000
begin
insert into CUSTOMER (CUSTOMER_ID, CUSTOMER_NAME)
VALUES (@COUNT, '12345678901234567890')
SET @COUNT = @COUNT + 1
END
Look again at statistics it does not have 2000 rows in here.
If i do select * from CUSTOMER where CUSTOMER_ID = '2000' then go checks statictics it works.
I was under the impression that when you do insert or delete, update then the statistics are fired.
The sys.sysindexes rowmodctr shows the 1000 rows.
I checked the conditions that sql fires if the no of rows int able > 6 and < 500 then updates when 500 mods made.
Also if row > 500 auto update done when 500 = 20% are added
So both are met.

I have installed the reports for the performance dashboard and really like it!
However, I'd like to be able to clear the stats in order to run specific procedures etc and see the most inefficient parts in the specific procedure. The documentation says like this about it:
The lifetime of the DMV data depends on the lifetime of the plan in cache. You can determine how long the plan has been cached, and thus the time frame over which these resources have been consumed, by looking at the Plan Cached column
What Plan Cashed column? Can someone explain to me how to clear the stats?
