Bcp Single CPU Vs Multiple CPU
Oct 20, 2001
I'm doing a BCP of a large table 37 million rows. On a single CPU server, SQL 7, sp 3, with 512 meg of RAM, this job runs in about 3 hours. On a 8 way server with 4 Gig of RAM, SQL 7 Enterprise, this job runs 12 hours and is only a third done. The single CPU machine is running one RAID 5 set while the 8 way server is running 4 RAID 5 sets with the database spread out over two of them.
Is there something obvious that a single CPU box would run this much faster?

Hi,
I have multiple columns in a Single Table and i want to search values in different columns. My table structure is
col1 (identity PK)
col2 (varchar(max))
col3 (varchar(max))
I have created a single FULLTEXT on col2 & col3.
suppose i want to search col2='engine' and col3='toyota' i write query as
SELECT
TBL.col2,TBL.col3
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col2,'engine') TBL1
ON
TBL.col1=TBL1.[key]
INNER JOIN
CONTAINSTABLE(TBL,col3,'toyota') TBL2
ON
TBL.col1=TBL2.[key]
Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.
I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information.
for e.g.;
i was thinking to concatinate both fields like
col4= ABengineBA + ABBToyotaBBA
and in search i use
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result = 1 row
But it don't work in following scenario
col4= ABengineBA + ABBCorola ToyotaBBA
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result=0 Row
Any idea how i can write second query to get result?

How to insert single row/multiple rows into multiple tables by using single insert statement.

Mar 21, 2008
Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob

Hi everyone,
Im having a hard time deciding what approach should I take. The scenario is this: I have developed various systems (inventory, HR, accounting, etc.). All this systems are (and should be) tightly integrated with one another. At present, for all these systems, i've used a single DB prefixing the tables with the systems name (eg. Inventory.Items).
My question is: did I did the right (and practical) thing? Or should I create a DB for each system to organize them? The problem with multiple DBs is some system uses the other system's table(s). Example, if i created a separate DB for accounting, and a separated DB for inventory, and another for HR, how am I going to relate inventory and HR's accounts to the accounting DB's table? I want a single instance for each table; I don't want to create another account table for inventory or HR so I can enforce integrity. And if different DBs, is there a performance impact on this?
Or is there another way? My concern is performance and manageability. Please help. Thanks!

I am looking for a simple way to do multiple values in one single parameter in my simple Stored Procedures. Let's say for example I have a column called RoomNumber and the value data type is INT. Here is my Stored Procedures:
CREATE PROC ROOMVACANCY
@RoomNumber int,
SELECT vacancy, roomnumber
FROM hoteldb
WHERE Vacancy IN (@RoomNumber)
END
The value for roomnumber has 100 records. I want to be able to select for more than selection when I execute this stored procedures. How do I do that in the simple way?

Can an Update statement support multiple SET/WHERE clauses? The following example won't work, but this is what I'd like to be able to do:
Code Snippet
UPDATE [CPSAgacar].tmp_CTA2
SET [Admit Date] = NULL
WHERE [CPSAgacar].tmp_CTA2.CalcAdmitDate IS NOT NULL
SET CalcDischDate = Discharge
WHERE [CPSAgacar].tmp_CTA2.CalcAdmitDate IS NOT NULL AND CPSAgacar].tmp_CTA2.CalcDischDate IS NULL
Thanks.

I have 2 systems that will send data to each other. Each system will originate a particular set of messages, there will be no overlap. This scenario has transaction data going to a reporting system and management operations going back to the transactional system. It is semi-related data.
I have two patterns in mind, a combined stream of all messages or 2 streams of segregated messages.
A. A single service on each instance would originate a set of messages, process the responses, and receive the other instance's messages. The responses and original message from the other system would mix on the same Q. The activation procs would have to handle all message types. The same infrastructure (message types, contracts, Qs, activation stored procs) would be created on both systems. Although, distinct service names and ports would be used on each instance.
B. Two services and two Qs. 1 service would originate a set of messages, process the responses. The other service would process messages from the other system. The responses and original message from the other system would be on the separate Qs. There would be 2 infrastructures created. There could be separate activation stored procs.
There is just one message type and message validation is only WELL_FORMED_XML.
Which is pattern is better for management and performance? Should I create 1 service or 2 on each instance? Either way should work about as well as the other? 2 services are twice as complex to set up. Separation is not necessary, but I like the idea. 1 service will send many more messages (>10x) than the other. Any thoughts?

Hi All,
We've a table as in the following format:
PK_Column1
PK_Column2
Issue_Date1
Issue_Amount1
Issue_Category1
Issue_Reject1
Issue_Date2
Issue_Amount2
Issue_Category2
Issue_Reject2
We need to divide it into two new tables as follows:
UniqueID
PK_Column1
PK_Column2
And
UniqueID
PK_Column1
PK_Column2
Sequence_ID
Issue_Date
Issue_Amount
Issue_Category
Issue_Reject
Unique1
1
Issue_Date1
Issue_Amount1
Issue_Category1
Issue_Reject1
Unique2
2
Issue_Date2
Issue_Amount2
Issue_Category2
Unique3
1
xx
xx
Unique4
2
xx
xx
Unique5
3
xx
4
xx
There will be one UniqueID for each row.
We'll get the uniqueID and PK1 and PK2 in a file.
Imp: We need to generate the Sequence_Id depending on number of Issue_dates or Issue_amounts or Issue_Categories or Issue_Rejects as in the above table.
Can we do this without using cursors?
This is going to be one time process.
Any ideas are appreciated.
Thanks,
Siva.

I would like to spread this across a few (or several) files, with the data distributed evenly (or close to it).
In other words, I would like to have, say 10 files in [PRIMARY] each with 10GB.
Any thoughts on how to make this happen?

Hi. I want to return multiple rows into a single row in different columns. For example my query returns something like thisThe query looks like thisSelect ID, TYPE, VALUE From myTable Where filtercondition = 1ID TYPE VALUE1 type1 121 type2 152 type1 16 2 type2 19Each ID will have the same number of types and each type for each ID might have a different value. So if there are only two types then each ID will have two types. Now I want to write the query in such a way that it returnsID TYPE1 TYPE2 VALUE1 VALUE21 type1 type2 12 152 type1 type2 16 19Type1, Type2, Value1, and Value2 are all dynamic.

I'm having trouble doing backups of several databases (on a single server) to one device (a disk file).
I created a script with each DUMP statement and when I run it from the query window, it works
just fine. But when I create a stored procedure out of the same script, I get errors because the
second DUMP statement is trying to access the device that is already being written to by the
first DUMP statement.
If I split them apart into different stored procedures, then they seem to overwrite each other and
I end up with only the last database backed up.
I'm trying to put this into a task and that is why I need to put it into stored procedures.
Is there a synchronous/asynchronous setting or parameter that I should be using? For now, I'm
just dumping each to separate devices, but this is a little sumbersome, since I have four
databases to backup for each day of the week. Which gives me a total of 28 separate
devices.
I'm sure there is a better way of doing this. Does anyone have any suggestions. Thank you in
advance.

was hoping someone couild provide some insight into a problem I'm trying to solve.
I have a table called SEARCHCRITERIA. It consists of a USERID column and a CRITERIA column. Users will be able to search for other users based on a set of criteria. There are 5 total criteria a user can choose. They can choose as few as none or all five. I'd like to store the criteria chosen as a single number in the SEARCHCRITERIA table. Then use a function to parse out the criteria. For example:
CRITERIAID CRITERIA CRITERIAVALUE
1 AGE 2
2 SEX 4
3 GRADE 8
4 LOCALE 16
5 REGION 32
A user performs a search based on AGE, SEX, and LOCALE. I would then store the value 22 (the sum of 2, 4, and 16) in the SEARCH table. I would then need a function to pull out the three individual values.
Has anyone done anything like this before?
If so, any help would be appreciated!
Thanks in advance!

I have a table that contains many columns in a single row and I'd like to split the table so that it has fewer column values and more rows.
My table structure is:
create table #scoresheet
(Decisions varchar(10), DNumericalValue int, DVI varchar(10), DComments nvarchar(255),
Competence varchar(10), CNumericalValue int, CVI varchar(10), CComments nvarchar(255),
Equipment varchar(10), ENumericalValue int, EVI varchar(10), EComments nvarchar(255));
I would like to have three rows with four columns.
What I've done so far is create a stored procedure that uses a table variable:
create procedure sp_splitsinglerow as
declare @Scoresheet_rows_table_var table (
ReviewArea varchar(25),
NumericalValue int,
VI varchar(10),
Comments nvarchar(255));
insert into @Scoresheet_rows_table_var
(ReviewArea, NumericalValue, VI, Comments)
select Decisions, DNumericalValue, DVI, DComments
from #scoresheet
The trouble with this approach is that I have to explicitly name the columns that I insert into the table variable. What I'd really like to be able to is have a loop construct and select the first 4 columns the first time, the second 4 the next time and the last 4 the third time.
Any ideas on how to achieve that?
BTW, I have resolved this issue by suggesting to the Developers that they change the structure of the original table, but I'd still like to know if there is another solution. :)

I am setting up a 40 subscriber node transactional replication environment (pull), and was looking to have 2 or more distributors service one publisher, each having a group of subscribers, is there any benefit to this ?, as opposed to having one distributor service all subscribers, is it possible (distributor at instance level ?)
From what I've seen, I could not find anything that shows multiple distributors to one publisher.
Publisher and Distributor are on separate physical hosts.

I am working with some old code that we are trying to clean up and perform some performance enhancements. The performance is now, so Very much better. From over 3 minutes to under 2 seconds.
But I am still trying to get the multiple rows into a single row. I would like to place this into a CTE to get the multiples into a single row. I just cannot get my head around how is the best, most efficient way to write the query.
This is a small example of what the rows look like in the resultset, and what I want to single to be.
DECLARE @BillingCorrect TABLE
(
ContractNumber char(10)
, pc1 int
, pb int
, om int
, vp int

I am not sure how to write the query to have all the data in a single row.
