I want to iterate this query using a loop as many as 5 times max.
We have a view with many left joins. The original creators of this view might have been lazy or sloppy, I don't know. I have rewritten the query to proper inner joins where required and also nested left joins.
So rather then the following exemplary fragment
select <many items>
from A
left join B on B.id_A = A.id
left join C on C.id_B = B.idthis now looks like
select <many items>
from A
left join (B
join C on C.id_B = B.id
) on B.id_A = A.id
Compilation time of the original view was 18s, of the new rewritten view 4s. The performance of execution is also better (not counting the compile of course). The results of the query are identical. There are about 30 left joins in the original view.
I can imagine that the optimizer has difficulty with all these left joins. But 14s is quite a big difference. I haven't looked into detail in the execution plans yet. I noticed that in both cases the Reason for Early Termination of Statement Optimization was Time Out.
MS SQL 2008.I want to execute a delete query on certain tables in my database to delete some rows in the tables.The tables selected has a certain name pattern (the name ends with "Temp").
So I can do this to get a list of the table names
SELECT name
FROM sys.Tables where
name like '%Temp'
Now I want to check each table to see if it has a column with the name "DateStamp" and then execute a delete query as follows:
delete form TableName where
DateStamp is < '2010-01-01'
In other words I need to iterate through the tables names, How to do this?
Hi,
Another classic example of something silly I must be doing
I have a "Foreach Loop Container" which uses a "Foreach ADO Enumerator".
The object source is a recordset variable.
Inside the "Foreach Loop Container", a lot of things are happening - some Execute SQL Tasks, Send Mail Tasks, Script Tasks and also a couple of Sequence Containers.
Now, I am getting 2 records in the recordset, but, the "Foreach Loop Container" executes just once.
Any Ideas?
Thanks in advance.
Regards,
B@ns

He wants to be able to work with the data on a workstation. Then, if he takes his laptop out of the office he wants to be able to simply plug that thumb drive into the laptop and fire up SQL on the laptop and use that same database. Procedurally this would work in that the database can be created so that the location is the same from both machine viewpoints, however will the two different SQL instances allow moving the database back and forth like this?

Function 2 = Clock Out Type 1
Function 3 = Clock In Type 2
Function 4 = Clock Out Type 2
Basically what I need to do is take the time from rows with Function 1 and match it with Function 2 so I can get a total time of the clock in. Function 3 rows need to match up with Function 4 rows so I can get another set of total times. There may be more clock in rows then clock out rows or more clock out rows then clock in rows, and there may be multiple clock ins & outs per day per employee. I'm basically trying to get totals for each Clock In/Out type.

View 6 Replies View RelatedProblem Summary: Merge Statement takes several times longer to execute than equivalent Update, Insert and Delete as separate statements. Why?
I have a relatively large table (about 35,000,000 records, approximately 13 GB uncompressed and 4 GB with page compression - including indexes). A MERGE statement pretty consistently takes two or three minutes to perform an update, insert and delete. At one extreme, updating 82 (yes 82) records took 1 minute, 45 seconds. At the other extreme, updating 100,000 records took about five minutes.When I changed the MERGE to the equivalent separate UPDATE, INSERT & DELETE statements (embedded in an explicit transaction) the entire update took only 17 seconds. The query plans for the separate UPDATE, INSERT & DELETE statements look very similar to the query plan for the combined MERGE. However, all the row count estimates for the MERGE statement are way off.
Obviously, I am going to use the separate UPDATE, INSERT & DELETE statements. The actual query plans for the four statements ( combined MERGE and the separate UPDATE, INSERT & DELETE ) are attached. SQL Code to create the source and target tables and the actual queries themselves are below. I've also included the statistics created by my test run. Nothing else was running on the server when I ran the test.

Can I safely use top n select/delete in a while loop? For example:
declare @FieldVal int
while (select count(*) from @MyTempTable) > 0
begin
select top 1 @FieldVal = FieldVal from @MyTempTable
-- process @FieldVal then delete the row
delete top 1 from @MyTempTable
end
I like the simplicity of the above approach as long as it's reliable and there aren't any gotchas that I may not be aware of.

The month will be set from a declared variable and the others will just be hard coded.

Hi there, I'm a little bit stumped on this one.
I have a column in a table that records when the date and time of an event took place.
Table Name: Chronicle
Column Name: Created (of type DateTime)
I would like to select the Chronicle records that are between two dates.
(e.g. 1 May 2001 and 20 May 2001)
And I would like to select those records that are between two times.
(e.g. 6:00am and 1:00pm)
Does anyone know how to do this or have any pointers for me?
I can see it would be easier if I had the date in one column and the time in the other.
Can it be done without doing that?
cheers,

We recently upgraded from SQL 6.5 to SQL 7. I have a few .sql files that were each running around 5 - 8 minutes under 6.5. These same files now each take over 30 minutes to run. Has anybody had problems with their queries taking longer to run under 7.0? These files are quite large and are comprised of 3 - 4 batches with several queries in each batch. If anybody has any thoughts on the cause please let me know.
Thanks in advance.
Hi,
I'm in an unfortunate situation. We are posting information using a stored procedure to an outside SQL server connected to through a System DSN on our server (win 2003 server) using php's ODBC functions (we never had any luck connecting directly to the SQL server using php's mssql functions).
Everything is working fine, we can connect, send querys, etc ... but between 1am and 10am we recieve errors when trying to execute queries (though we can connect fine).
Whoops ... forgot to get the error returned before it turned 10am ... I can post it tomorrow
I think the database is being locked, but unfortunately I know very little about MS SQL server
The people who's database we are connecting to are not being helpful ... I was hoping I could get some suggestions on what would be the cause.
Anything you can suggest would be a huge help! Thanks!

We are having a problem with Query Analyzer not connecting to SQL Server anymore. Sometimes it will, sometimes it won't. Sometimes when it does, then you click on the databases drop-down, it may take a long time to return. Likewise, it may take a long time to open the object browser, or it may open without the database info but with just the "Common Objects" info.
All of this used to work just fine.

Simple version first:
The basic question is:
what would cause? this query takes minutes or times out:
select xx,xx,xx,xx
from view_xxx
where field in
(
select distinct xxx from table inner join table.....
)
the inner query
select distinct xxx from table inner join table..... takes less than a second
then if I take the results of that query and do this:
select xx,xx,xx,xx
from view_xxx
where field in
(
52193,23523,25233... and so on
)
this later query takes 2 seconds... What is the difference? For more details see the detailed version.

now a more details version:

What would cause this query to take forever, or even timeout:

SELECT ORD.CONTROL_ID
FROM Orders ORD
INNER JOIN Providers PR ON PR.SUBJECT_ID = ORD.SUBJECT_ID and PR.SV_OFFICE_ID = ORD.SV_OFFICE_ID and PR.Source_ID = ORD.Source_ID
INNER JOIN VisitTypes VT ON ORD.VISIT_TYPE_ID = VT.VISIT_TYPE_ID and ORD.Source_ID = VT.Source_ID
INNER JOIN HealthPlans HP ON HP.MARKET_ID = ORD.MARKET_ID and HP.Source_ID = ORD.Source_ID
INNER JOIN HPGroups HPG ON HP.MARKET_ID = HPG.MARKET_ID AND HP.SOURCE_ID = HPG.SOURCE_ID WHERE (ORD.Status is not null AND ORD.Status <>'E')
AND HPG.GR_ID in
(
SELECT GR_ID from UserHPGroups Where User_ID= 7
)
AND ORD.RELEASED_DATE between '01/01/2001' and '02/11/2008'
and ORD.RECEIVED_DATE between '07/01/2007' and
'12/31/2007' and ORD.MARKET_ID= 2699431

as mentioned above the inner query takes less than 1 second. So if I take the results from that query and do a select like this:

Problem : city name the same
I have a person table with 1 billion rows on it, partitioned equally at 10 million rows per partition. The primary key constraint is a composite of an identity column and ssn( char(11) ) with the partitioning column built on the SSN.
This is built on my home grown workstation:
Microsoft 2008 Server 64 bit, Microsoft SQL server 2008 64 bit, Intel 2.66 quad core, 8 gb ram, Os/ raid 1, data on 6 drives hardware/software raid 50, transaction logs on 4 drive raid 10, all drives sata II/ 3gb burst.
I have updated statistics on the table and I have 2 queries that give clustered index seek , one never comes back before I get impatient, the other comes back instantly, and the showplan looks the same for both queries.
SELECT *
FROM Person
WHERE PersonKey > -1 and SSN = '219-09-3987'
AND
SELECT TOP 100 PERCENT *
FROM Person
WHERE PersonKey > -1 and SSN = '219-09-3987'
Incidentally the query with the top 100 percent is the one that returns instantly.
I am puzzled
1) Why the estimated plan looks the same
2) Why a top 100 Percent query is faster than one without it
