SQL Server 2014 :: Huge Number Of Rows In Table Spool

Jul 6, 2015

I have a CTE query against a table with 32K rows that runs fine in 2008R2. I am running it in 2014 Std Ed. against the same data and it runs very slowly. Looking at the execution plan I think I see what's contributing to the slowness.

Note that the "actual number of rows" is some 351M...how is this possible?

the query:

declare @amts table (claim int,allowed decimal(12,2),copay decimal(12,2),deductible decimal(12,2),coins decimal(12,2));
;with unpaid (claimID) as (select claimID from claim where amt+copay + disct+mm + ded=0)
insert @amts
select lineID, sum(rc), sum(copay), sum(deduct),
case when sum(mm)>0 and (sum(mm)<sum(mmamt)) then sum(mm) else 0 end
from claimln
where status is null
and lineID not in (select claimID from unpaid)
group by lineID

it's like there's some massively recursive process going on?

Table Spool Lazy Spool

Jul 20, 2005

What causes the query optimizer to choose a table spoollazy spoolaction in the execution plan? The explanation of "optimize rewinds"makes little sense because my query never comes back to that table.I'm going to have to change the query but it would be helpful if Iknew what I should be trying to avoid.David

The Best Way To Delete A Huge Number Of Records In Table

May 30, 2008

Hi Everyone,



We have a large test database with million of records for more than company site Code. Sometime we want to refresh the data of that database for one or more site Codes.

In order to do that I have to delete all records of the site code we want to refresh on the test database first then copy a new set of data from production database over. Since we refresh data based on the site code therefore I have to use the Delete command instead of Truncate.

Since this is a huge database with thousand of tables and million of records per table I have a performance issues with delete command. So what would be the best to delete a large number of records without writing any information to database log file?



FYI: The Recovery model of this database is Simple


Regards,



Jdang

Database Table Design For Huge Number Of Columns

Jan 24, 2008

Hi

I have a table (Sql server 2000) which has 14 cost columns for each record, and now due to a new requirement, I have 2 taxes which needs to be applied on two more fields called Share1 and share 2
e.g
Sales tax = 10%
Use Tax = 10%
Share1 = 60%
Share2 = 40%

So Sales tax Amt (A) = Cost1 * Share1 * Sales Tax
So Use tax Amt (B) = cost1 * share2 * Use tax

same calculation for all the costs and then total cost with Sales tax = Cost 1 + A , Cost 2 + A and so on..
and total cost with Use tax = Cost1 +B, Cost 2 +B etc.

So there are around 14 new fields required to save Sales Tax amt for each cost, another 14 new fields to store Cost with Sales Tax, Cost with Use tax. So that increases the table size.
Some of these fields might be used for making reports.

I was wondering which is a better approach out of the below 3:
1) To calculate these fields dynamically while displaying them on the User interface and not save in DB (while making reports, again calculate these fields dynamically and show), or
2) Add new formula field columns in database table to save each field, which would make the table size bigger, but reporting becomes easier.
3) Add only those columns in database on which reports needs to be made, calculate rest of the fields dynamically on screen.

Your help is greatly appreciated.
Thanks

                                1-  How do I find out if this table is not being referenced by a FOREIGN KEY?

SQL Server 2014 :: Incrementing Number In Table And Then Resetting Column

Jul 15, 2015

I have four columns in my table, the first one is the identity column

SQL Server 2014 :: Counting Corresponding Rows In Table

Mar 21, 2015

Select statement joining file1 to file2. File 1 may have 0, 1, or many corresponding rows in file2. I need to count the corresponding rows in table2. Table2 also has a Boolean column and I need to count the number of rows where it is true. So I need to count the total number of matching rows and the count of those that are set to true. This is an example of what I have so far. I had to add each column being selected into a Group by to make it work, but I do not know why. Is there some other way this should be set up.

SELECT c.CarId, c.CarName, c.CarColor, COUNT(t.TrailerId) as trailerCount, (add count of boolian, say t.TrailerFull is true)
FROM Car c
LEFT JOIN Trailer t on t.CarId = c.CarId
GROUP BY c.CarId, c.CarName, c.CarColor

SQL Server 2012 :: Insert Rows Based On Number Of Distinct Values In Another Table

May 20, 2014

I have a table with PO#,Days_to_travel, and Days_warehouse fields. I take the distinct Days_in_warehouse values in the table and insert them into a temp table. I want a script that will insert all of the values in the Days_in_warehouse field from the temp table into the Days_in_warehouse_batch row in table 1 by PO# duplicating the PO records until all of the POs have a record per distinct value.

Example:

Temp table: (Contains only one field with all distinct values in table 1)

Days_in_warehouse
20
30
40

Table 1 :

PO# Days_to_travel Days_in_warehouse Days_in_warehouse_batch
1 10 20
2 5 30
3 7 40

Updated Table 1:

PO# Days_to_travel Days_in_warehouse Days_in_warehouse_batch
1 10 20 20
1 10 20 30
1 10 20 40
2 5 30 20
2 5 30 30
2 5 30 40
3 7 40 20
3 7 40 30
3 7 40 40

How can I update Table 1 to see desired results?

Huge Deletes In A Huge Table

Apr 3, 2000

SQL 7 SP1 NT4 SP5

I have a TRANSACTION table with 150 million rows.

I have a USER table.

Each user has about 600 records in the TRANSACTION table.

The TRANSACTION cluster index is on USERID + RECID . The second index is on USERID + Fieldx + Fieldy.

The TRANSACTION table gets about 1.4 million inserts in a normal day and about 40,000 updates.

I want to go through the USER table and delete all users who have not visited me in a while.

I want to do this without substantially hindering performance in a production environment. I can perform this over a week period or two if needed.

The best way I thought of doing this was to grab x amount of users in a cursor and loop through deleting their corresponding TRANSACTION records.

Does anyone have any ideas on a better way. What is going to happen to my indices during this time ?

Thanks !!!

PULL Huge Table From SQL Server Problem

Jul 12, 2007



Hey Guys

I have meet the same problem, too.

I create a table with 1,380,000 rows data,

the db real size about 114 MB.

The primary key size is nchar(6).

When I use RDA pull, I found that the primary

key in the PDA disappear. So, It took a long time

to get query response.

But when I delete some rows to 680,000 rows of data.

After I pull, The primary key can pull from the SQL Server.

PS: I didn't change any code. Just delete some rows.

Is that SQL-Mobile's bug??



PS: 1.Database and Temp Database limitation both are 384MB

2.If I use query analyzer to add primary key it works! so strange!!

3.Pull process return "S_OK".

4.After Pull process finished, the db connection still alive. It seems not like

time out problem.

5.Local Connection String:"Data Source='%s\%s';SSCEatabase Password='%s';SSCE:Encrypt Database='true';SSCE:Max Database Size=384;SSCE:Temp File Max size=384;SSCE:Temp File Directory=%s"

How To Spool Into A Script File In SQL Server?

Sep 18, 2005

Hi friends,
Suppose that I want to generate an script that has a
"DROP TABLE <table_name>;" for each table in one of our databases.In Oracle I can do this using "spool" command in "SQL Plus" which is a commandline utility somewhat like isql or osql(I don't know these two perfectly! ).For example:

Code:

spool c:DropAllTables.sql
select "DROP TABLE "||table_name||";" from user_tables;
spool off



And this will generate that script with many drop within that.Would you please clarify me, if there is such a thing in SQL Server 2000?
-Thanks a lot
