SQL Optimistic (all In One Table Split Into Two Table)
Dec 18, 2007
I having a bit of confuse here. Can you please help me?
I have about 5000 records all ready in oen table. Everything that I query is related to that table one way or the other. Now i having 2000 - 3000 more records to store in the database. In term of relation database then I can store the new data in a different table so I can can query it. Most of my queries are searching.
So the question is is this better to store the data in another table or should store everything in the old table? Thanks a lot in advance for your help. I really do appreciate that.

Hello,I am using SQL 2005 and Cognos' Data Manager. It is an ETL tool fordata warehousing.I have a problem with time it takes to load new changes, and I amseeking advice on a better way to manage the data.I have a table that tracks student attendance and it contains about 13million records. On a daily basis, there are 5,000 - 20,000 inserts and10,000 - 50,000 updates.The daily data comes for two different text files from my operationsystem; current and historical (CLSFIL and CLSHIS).The data is loaded into a staging area from the operational system,where data cleansing and other fields are added to the table.The final step is delivering the table to my target database, which isused for reporting.Heres the situation: I find it takes 45 minutes to do a relationalupdate, where only the records that changed in the last day will beloaded. However, if I choose the native API load instead of aRelational Load, it can load all 13M records in 7 minutes. The table isheavly indexedAt some point, the API load will take more time than the relationalload, (the changes and new records will remain a constant, but the filewill continue to grow).I'm seeking another solution is more efficient. I'm considering twotables for history and current and creating a view for reporting via aunion.This a good idea? How can I make the view effeicent to use the whereclause? Looking to bounce around ideas.Other Ideas?Thanks in AdvanceRob(I maintain the key relationships in the tool, not the tables. I knowI have lots to learn and improvments)CREATE TABLE "dbo"."F_BI_Class_Attendance_Detail"("CLASS_ATTENDANCE_ID" VARCHAR(50) NULL,"CLASSES_OFFERED_ID" VARCHAR(26) NULL,"CLASS_CAMPUS_ID" VARCHAR(10) NULL,"STUDENT_ID" CHAR(20) NULL,"FULL_CLASS_ID" CHAR(15) NOT NULL,"SESSION_ID" CHAR(10) NULL,"SECTION_ID" VARCHAR(5) NULL,"MEET_DT" DATETIME NULL,"MEETING" SMALLINT NULL,"PRESENT" CHAR(2) NOT NULL,"SESSION_SKEY" BIGINT NULL,"STUDENT_SKEY" BIGINT NULL,"CLASS_CAMPUS_SKEY" BIGINT NULL,"CLASSES_OFFERED_SKEY" BIGINT NULL,"LOAD_DT" DATETIME NULL,"COMPUTED_DT" DATETIME NULL);

So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.

Hi Guys
I have an application that runs on several sites that has a table with 36 columns mostly ints och small varchars.
I currently have only one table that stores the data and five indexes and since the table on one location (and others soon) has about 18 million rows I have been trying to come up with a better solution (but only if needed, I dont think I have to tell you that I am a programmer and not an dba).
The db file size with all the indexes is more then 10gb, in it self is not an problem but is it a bad solution to have it that way?
The questions are:
Are there any big benefits if i split it into several smaller tables or even smaler databases and make the SPs that gets the data aware that say 2006 years data is in table a and so on?
Its quite important that there are fast SELECTS and that need is far more important then to decrease the size of the database file and so on.
How many rows is okay to have in one table (with 25 columns) before its too big?
Thanks in advance.
Best regards
Johan, Sweden.

What's the best way to convert a large set of records from a simple schema where all fields are in one table to a schema where fields are split across two tables? The two table setup is necessary for reasons not worth getting into here.
Doing this via cursor is pretty straightforward, but is there a comparable set-based solution?
Here are sample create table commands. Obviously, the example below is simplified for discussion purposes.
-- One record from here will produce a record in TargetParentRecords and a record in TargetChildRecords for a total of two records.
CREATE TABLE OriginalSingleTableRecords (
ID INT IDENTITY (1, 1) NOT NULL,
ColumnA VARCHAR(100) NOT NULL,
ColumnB VARCHAR(100) NOT NULL,
CONSTRAINT PK_OriginalSingleTableRecords PRIMARY KEY CLUSTERED (ID)
)
CREATE TABLE TargetParentRecords (
ParentID INT IDENTITY (1, 1) NOT NULL,
ColumnA VARCHAR(100) NOT NULL,
CONSTRAINT PK_TargetParentRecords PRIMARY KEY CLUSTERED (ParentID)
)
-- Each row in this table must link to a TargetParentRecords row
CREATE TABLE TargetChildRecords (
ID INT IDENTITY (1, 1) NOT NULL,
ParentID INT NOT NULL, -- References TargetParentRecords.ParentID
ColumnB VARCHAR(100) NOT NULL,
CONSTRAINT PK_TargetChildRecords PRIMARY KEY CLUSTERED (ID)
)

Hi,
I have Data split into 3 text files with 3 fields repeated in each to link then (key). I want to import this data into one table.
I used DTS to create 3 tables with the data. Now i want to combine the 3 tables into only one (that i already created). How can i do this? Note: the field names in the source tables are different from the destination table.
Thanks

Hello,We maintain a 175 million record database table for our customer.This is an extract of some data collected for them by a third partyvendor, who sends us regular updates to that data (monthly).The original data for the table came in the form of a single, largetext file, which we imported.This table contains name and address information on potentialcustomers.It is a maintenance nightmare for us, as prior to this the largesttable we maintained was about 10 million records, with lesscomplicated updates required.Here is the problem:* In order to do the searching we need to do on the table it has 8 ofits 20 columns indexed.* It takes hours and hours to do anything to the table.* I'd like to cut down as much as possible the time required to updatethe file.We receive monthly one file containing 10 million records that arenew, and can just be appended to the table (no problem, simple importinto SQL Server).We also receive monthly one file containing 10 million records thatare updates of information in the table. This is the tricky one. Theonly way to uniquely pair up a record in the update file with a recordin the full database table is by a combination of individual_id, zip,and zip_plus4.There can be multiple records in the database for any givenindividual, because that individual could have a history that includesmultiple addresses.How would you recommend handling this update? So far I have mostlytried a number of execution plans involving deleting out the recordsin the table that match those in the text file, so I can then importthe text file, but the best of those plans takes well over 6 hours torun.My latest thought: Would it help in any way to partition the tableinto a number of smaller tables, with a view used to reference them?We have no performance issues querying the table, but I need somethoughts on how to better maintain it.One more thing, we do have 2 copies of the table on the server at alltimes so that one can be actively used in production while we runupdates on the other one, so I can certainly try out some suggestionsover the next week.Regards,Warren WrightDallas

Hello
I'm working on a package which loops through each xml file in a folder.
The name of each xml file is put in variable.
The format of the filename is something like "part1_part2_part3.xml"
I need to store the 3 parts in three different columns of table A
The content of the xml file needs to be manipulated ("." needs to be replaced with ",", ....)and put in serveral columns in tableB
It's not clear to me yet how to start this but my main concern is read the three parts of the filename. I don't find any task in SSIS which could help me with that.
Could someone give me some pointers?
Many thanks!

I imported all rows of my txt file using SSIS 2005 into a table. I am now trying to figure out how to split out the header, payment rows, and maintenance rows. First, some information.
An example of table results is here:
http://www.webfound.net/split.txt
The table has just one field of type varcha(100) because the incoming file is a fixed length file at 100 bytes per row
The header rows are the rows with HD in them...then followed by detail rows for that header (see here http://www.webfound.net/rows.jpg).
I need to
1) Split out the header into a header table
2) Split out the maintenance rows (related to the header) into a maint table
3) Split out the payment rows (related to the header) into a payment table
I'll need to maintain a PK/FK relationship between each Header and it's corresponding maint and payment rows in the other 2 tables.
To determine if it's a payment vs. maintenance row, I need to compare chars 30 - 31. If it contains 'MT' then you know it's a maintenance row, else it's a payment row.
How in the hell do I do this???

Hi Guys,
I have this table formatting problem; I have a table report (with rows expanding) say sales report for items. In this report each item has 2 rows. I want to split the send row as shown below. So the results of the report should have the format below.
rownumber
ITEMNUNBER
COST
Sales
On Hand
1
A
CY4567
CY6780
CY567
2
A
LY4678
LM678
LY7999
LM789
LY500
LM10
3
B
4
B
5
C
6
C
IN this example for each item we show current year, last year and Last month Cost,sales and on hand.
This is not a cross tab and number of items onthe report varies. In this example its 3 items but next time when you run it could be 100 items.
Any help appreciated

I've been searching the forums and Google for some help splitting up rows in a table without any luck. I'm not quite sure what to even look for
I have a table is MSSQL 2000 that looks as follows:
Code:
id custnum b1_email b2_email b1_sub b2_sub
------------------------------------------------------------------------
1 123456 b1@host1.com b2@host1.com 0 0
2 654321 b1@host2.com b2@host2.com 1 0
3 321654 b1@host3.com b2@host3.com 0 1
Now... I am hoping create a view that splits these rows up so that only a single email address is on each row. I'd like to split it up as follows:
Code:
custnum email sub
----------------------------------
123456 b1@host1.com 0
123456 b2@host1.com 0
654321 b1@host2.com 1
654321 b2@host2.com 0
321654 b1@host3.com 0
321654 b2@host3.com 1
Any help would be great! I imagine some sort of join command can be constructed using a single table?

I have a string which is delimited by commas:
Green,Red,Blue,Orange,Black,White
I need to create a SQL statement to read the string, split it at the "," character, and insert it into individual rows. I also need to insert an ID (the same for all split values).
For instance:
INSERT INTO tbl_Temp (unique_id, ID, color) VALUES (1, 999, Green)
INSERT INTO tbl_Temp (unique_id, ID, color) VALUES (2, 999, Red)
INSERT INTO tbl_Temp (unique_id, ID, color) VALUES (3, 999, Blue)
etc...
I would like to be able to do this all in one statement so I don't have to break it out into individual SQL statements.

Let me see if I can explain my situation clearly.I have a table with the columns:answer_id, question_id, member_id, answer- answer_id is the primary key for the table.- question_id relates to another table with questions for a user. Thetable holds the question and the possible choices in a varchar fieldseparated by a delimiter.- member_id is self-explanatory- answer is a varchar field of all the choices the user selected,separated by a delimiter.Here is my problem.I am trying to search all members that have answered, say, question_id= 2 where they selected 'brown' as one of their choices.i can do this if they selected ONLY that item, but not multiple items.The problem is this portionanswer in(select valu from dbo.iter_intlist.....I need this to be something like....function_to_return_all_separated_answers(answer) in(select valu from dbo.iter_intlistThe current way, it is only returning members that have an answer'Brown', not 'Brown, Blue' in their answer field.

Thanks for reading.
This is pretty long, hopefully it isn't rambling.
I'm building a system that imports data from several source, Excel files, text files, Access databases, etc. using DTS. The entire process revolved around MS SQL Server, by the way.
I figured I would create denormalized tables that mirror the Excel and flat files, for example, in structure, import data to those, clean up and remove duplicates there, then break those out into my normalized table structure later.
Now I've finished the importing part (though this is going to happen once a week) and I'm onto breaking up the denormalized tables.
I'm hesitating because I'm not sure I've made the best decisions in terms of process, etc.
I've decided to use cursors to loop over the denormalized tables and use batch insert statements to push data out to the appropriate tables.
Any comments? Suggestions? All is welcome.
I'm specifically interested in hearing back on the way I've set up the intermediate, denormalized tables and how I'm breaking them up using cursors (step 2 of the process below). Still, all comments are welcome. As are suggestions for further reading.
Thanks again...
simplified example
(my denormalized tables are 20 - 30 colums wide)
denormalized table:
===================
name, address, city, state, cellphone, homephone
normalized tables:
==================
tblPerson [PK_person, name, age, height, weight]
tblAddress [PK_address, FK_person, street, city, state, zip, addressType]
tblContact [PK_contact, FK_person, data, contactType]
I'm breaking up the denormalized tables like this (*UNTESTED*):
=================================================
DECLARE @vars.... (one for each column in my normalized table structure, matching size and type)
DECLARE myCursor CURSOR
FAST_FORWARD FOR
SELECT name, address, city, state, cellphone, homephone
FROM _DNT_myWideTable
INTO
WHILE @@Fetch_Status = 0
BEGIN
-- grab the next row from the wide table
FETCH NEXT FROM myCursor
INTO @name, @address, @city, @state, @cellphone, @homephone
-- create the person first and get the ID with @@IDENTITY
INSERT INTO tblPerson (name) VALUES (@name)
SET @personID = @@IDENTITY
-- use that ID to coordinate inserts across other tables
INSERT INTO tblAddress (FK_person, address, city, state, addressType)
VALUES(@person, @address, @city, @state, 'HOME')
INSERT INTO tblContact (FK_person, data, contactType)
VALUES(@person, @cellphone, 'CELLPHONE')
INSERT INTO tblContact (FK_person, data, contactType)
VALUES(@person, @homephone, 'HOMEPHONE')
END

I have a transaction table that has a composite key made up of transaction id and product id. where multiple products were purchased under same transaction, transaction ids got repeated.
I would like to split the table randomly into 70%, 30% ratio to create training and testing set respectively in such a way that it does not split a same transaction under which multiple products were purchased (rows with same transaction id should not get split).
is it possible? if possible what is the idea?
It would be of great help.
Thanks.

I have a table with a string value, where all values are seperated by a space/blank. I now want to use SQL to split all the values and insert them into a different table, which then later will result in deleting the old table, as soon as I got all values out from it.
Old Table:
Code:
ID, StringValue
New Table:
Code:
ID, Value1, Value2
Do note: Value1 is INT, Value2 is of nvarchar, hence Value2 can contain spaces... I just need to split on the FIRST space, then convert index[0] to int, and store index[1] as it is.
I can split on all spaces and just Select them all and add them like so: SELECT t.val1 + ' ' + t.val2... If I cant find the first space that is... I mean, first 2-10 characters in the string can be integer, but does not have to be.Shall probably do it in code instead of SQL?Now I want to run a query that selects the StringValue from OldTable, splits the string by ' ' (a blank) and then inserts them into New Table.
Code:
SELECT CASE CHARINDEX(' ', OldTable.stringvalue, 1)
WHEN 0 THEN OldTable.stringvalue
ELSE SUBSTRING(OldTable.stringvalue, 1, CHARINDEX(' ', OldTable.stringvalue, 1) - 1)
END
AS FirstWord
FROM OldTable
Found an example using strange things like CHARINDEX..But issue still remains, because the first word is of integer, or it does not have to be...If it isn't, there is not "first value", and the whole string shall be passed into "value2".How to detect if the very first character is of integer type?
Code:
@declare firstDigit int
IF ISNUMERIC(SUBSTRING(@postal,2,1) AS int) = 1
set @firstDigit = CAST(SUBSTRING(@postal,2,1) AS int)
ELSE
set @firstDigit = -1
[code]....

I have a stored procedure that is passed two values. Both are strings representations of GUID values, the first is a single value, the second is a comma delimited string of values.In the stored procedure I call a split function to separate the comma delimited values into a table and this is used in my WHERE clause to filter my select results.This is an example:
Code:
SELECT
item.uiGUID as ItemGUID,
stores.strStoreName as Store,
location.strLocationName as Location
FROM tblItems as item
INNER JOIN tblStoreLocations as location
ON item.uiLocationGUID = location.uiGUID
INNER JOIN tblStores as stores
ON location.uiStoreGUID = stores.uiGUID
WHERE CAST(item.uiGUID as varchar(36)) IN (SELECT Value FROM dbo.Split(',',@ItemGUIDList))
When I run this query in the management studio, passing a list of 5 values in the second parameter, my results include one item for each of the 5 values. However, when I pass the parameters from my ASP project, (I've verified the values I think are being passed are indeed being passed), I only get one item.I believe the error is in my split function. Both split functions return the same results in the SQL management studio, but only one returns the correct results in the the ASP project.
When I use this version of the function it returns the correct table values to the calling application, but it chokes when the item list does not have a trailing comma. I figure that to be a bug in the SQL function.
Code:
CREATE FUNCTION [dbo].[Split]
( @Delimiter varchar(5),
@List varchar(8000)
)
RETURNS @TableOfValues table
( RowID smallint IDENTITY(1,1),
[Value] varchar(50)
[code]....

I have a source table which I'm splitting 3 ways based on a column value, but the target is the same OLE DB destination table. One conditional path is to a Multi-Cast two way split to same OLE DB gestination table. The default split is to a flat file for logging unknown record types. For a test I have data for only the 3 column values I want, but I'm having trouble with the process completing. If I pre-filter the data going into the source table by one or two values I can get the process to complete even if one split is to the multicast. If I include all three data types in the source table, I get different results depending on the order in which the conditions are specified - sometimes only two split paths are executed; other times all three are executed, but in some cases only one path of the multicast split is executed. In any case, when the three source data types are used in the test, the process never competes - the pathes are in a yellow condition and never complete.
Am I creating some kind of deadlock situation by having the source data directed to the same target table via 4 splits? Any help you can provide is appreciated. Thanks.

I have a table that has the following structure:
EntryID int,
Categories varchar(200)
values look like:
541,'A,B,C'
345,'B,C'
234,'A,C'
657,'D,E'
435,'D'
what I want to do is extract the Categories column to a normalized separate table:
541,'A'
541,'B'
541,'C'
345,'B' ....
I found the split using the tally table useful to split one-by-one, but how can it be applied when you are referring to a table?

Hi ,
I have two tables within a SQL database. The 1st table has an identified column and column which lists one of more email identifers for a second table,
e.g.
ID Email
-- ----------
1 AS1 AS11
2 AS2 AS3 AS4 AS5
3 AS6 AS7
The second table has a column which has an email identifier and another column which lists one email address for that particular identifier, e.g.
ID EmailAddress
--- ------------------
AS1 abcstu@emc.com
AS2 abcstu2@emc.com
AS3 abcstu3@emc.com
AS4 abcstu4@em.com
AS5 abcstu5@emc.com
AS6 abcstu6@emc.com
AS7 abcstu7@emc.com
AS11 abcstu8@emc.com
I need to create a stored procedure or function that:
1. Selects an Email from the first table, based on a valid ID,
2. Splits the Email field of the first table (using the space separator) so that there is an array of Emails and then,
3. Selects the relevant EmailAddress value from the second table, based on a valid Email stored in the array
Is there any way that this can be done directly within SQL Server using a stored procedure/function without having to use cursors?
Many Thanks,

We are using the Transfer SQL Server Objects Task to transfer a large table. The trans log is filling up for this table. Is there a method to split the Data Transfer Task into smaller batches? (Smaller tables are transferring without issue.)
Thanks.

Import.csv file looks like,
TABLE_NAME DESC CODE
tab1 table1 A
tab1 table1 B
tab1 table1 C
tab2 table2 D
tab2 table2 E
tab2 table2 G...
First column values are table names which are already exists in target database. Next two columns[Desc],[Code]Â data gets populate from CSV file to table.
In this scenario, how to load tab1 data into the same table in destination and so on.
Which way will be more standard to accomplish this task? If its a script task using C#, looking for clear script to identify a value changes in the first column.

Hi,I'm trying to implement Optimistic Concurrency in asp 2 but so far it has caused me nothing but problems.First, when doing an UPDATE I tried to use the primary key & a timestamp field which I had in SQL Express.. VS 2005 generated the stored procedures fine however when it came to the actual updating I think there was a problem with the conversion of the timestamp field when it was being stored in a text box (in a FormView control). So.. as a result that failed. And also I checked sooo many places online and haven't been able to find any examples of code where a timestamp was used with success in asp2.Next, I got ride of the timestamp type (in SQL Express database) and used a datetime and then.. I just implemented Optimistic Concurrency by passing in ALL the values (ie all the original values) like is proposed http://www.asp.net/learn/dataaccess/tutorial21vb.aspx?tabid=63 . This... works however I really do not want to have to pass in ALL these values (ie original and new).Ideally I would like to be able to use the primary key & the datetime field to handle the Optimistic Concurrency checks where only the original values of both those fields are passed back into the stored procedure. Now.. I tried this as well, but I kept getting an error that suggests that (for some reason) the FormView or DataSource is passing ALL the values (original & new) into the dataset as opposed to only the original primary key & datetime fields & the new set of values.Can ANYONE offer any help? I really would like not to have to pass in all these values.Thanks in advance!

I have a number of SqlDataSource objects in my application, which don't have Optimistic Concurrency option enabled. The SDS objects use custom Sql statements so I can no longer select the Advance button to enable Concurrent Concurrency.
How can I enable this option? Is there a designt ime property, and even a run time property that can be set?
The only method we have so far is to create a new SDS, with Optimistic Concurrency switched on, then copy and paste my custom Sql into it and rebind my components..
Any help on this matter is appreciated.
Regards,
Steven

hello allI am working with the visual studio web express using MSDE as sql server.Every thing is working fine with database except when working with optimistic concurrency.So if I have a GridView or FormView binded to a SqlDataSource that is configured to perform the concurrency, these controls can't perform the update to the database.From debugging, I found that the SqlDataSource Old Value Paramters always null after postback.Is this a bug in the WebExpress, or do I need to use the SqlExpress Edittion?Thanks in advance, and keep the good effort.Hesham
