T-SQL To Split Data From One Table Into Two Tables?
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)
)

Big Table(?) Or Split Between Tables?
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.

How To Split Out Table Rows Into 3 Tables
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???

Need To Find An Easy Way To Split A Column In Table Without Using Cursor Or Temp Tables
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, probetatester@yahoo.com

Deadlock Problem? 3 Way Conditional Split Of Data From One Table To Another Never Completes
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.

Design -- Should This Be Split Up Into A Few Tables?
I'm grappling with this design problem right now: I have a table of users. Every user has an e-mail address and (hashed) password. Some of those users work for a company, and some of them do not. Of those who do not work for a company, some are salespeople who sell to one or more companies. Some users are simply administrators who don't work for a specific company. So here's what my users table looks like right now: "UserID, Email, Password, CompanyID (Nullable), IsAdmin" And here's my companies table: "CompanyID, CompanyName, SalespersonID" Of course, I could separate it out and make a Users table, an Employees table, and a Salespeople table. The way the relationship works out, though, I could use the same ID number for all three tables, and that indicates to me that perhaps they all belong in the same table. It seems silly, after all to have a Salespeople table whose only field is "UserID." Two factors of the first design concern me: First is the fact that a salesperson could also have a company. I guess I could write a check constraint to prevent this, but doesn't having the companyID in the Users table violate a normalization rule? Maybe? The second is the fact that the Companies table relies upon Users, which in turn relies upon Companies. In OOP, this usually isn't a good thing, but I'm not sure whether it's cause for concern in a relational database. Anyway, I really don't know what I should be doing with this design. Any suggestions? Thanks in advance, -Starwiz

Split Row's Columns Across Multiple Tables
Hello, Hoping someone here can help. Perhaps I'm missing something obvious, but I'm surprised not to see a data flow task in SSIS for splitting *columns* to different destinations. I see the Conditional Split task can be used to route a *row* one way or another, but what about columns of a single row? As a simple and somewhat contrived example, let's say I have a row with twelve fields and I'm importing the row into a normalized data structure. There are three target tables with a 1-to-1 relationship (that is, logically they are one table, but physically they are three tables, with one of them considered the "primary" table), and the twelve input fields can be mapped to four columns in each of the three tables. How do I "split" the columns? The best way I can see is to Multicast the row to three different OLE-DB Destinations, each of which inserts to one of the three target tables, only grabbing the four fields needed from the input row. Or should I feed the row through three successive OLE-DB Command tasks, each one inserting into the appropriate table? This would offer the advantage, theoretically, of allowing me to grab the identity-based surrogate primary key from the first of the three inserts in order to enable the two subsequent inserts. Thoughts? Thanks in advance, Dan

How To Assign Unique PKs And FKs On Split Of Txt Rows Into DB Tables
SSIS 2005 Ok, I have a task in SSIS that does the following and works: 1) Brings in a txt file 2) Using a conditional component, checks for a value in the row. 3) Based on the value, splits the row into one of 3 tables (Header, Maintenance, or Payment) Here is a print screen of what I have so far which splits Header rows into it's own table, Maintenance rows into its own table, and Payment Rows into its own table: http://www.webfound.net/qst_how_to_add_header_PK_and_FKs.JPG Here is a print screen of the conditional split: http://www.webfound.net/conditional_split.jpg Please take a look at the txt file here before it's processed: http://www.webfound.net/split.txt http://www.webfound.net/rows.jpg Notice that the pattern is a header row, followed by it's corresponding detail rows. The detail rows are either Maintenance or Payment rows. I need to somehow during the Script component or some other way, to assign a unique HeaderID (PK) to each of the header rows and add that ID to it's corresponding Maintenance and Payment detail rows in their corresponding tables as a PK. The problem is 1) I don't know how to do this in the flow of the components as I have it now 2) How do I tell it to create a new Header ID and Header FKs for the detail rows based off of each new Header row? In the end (much later on in my entire package), the goal is to be able to run a stored proc to join and select the Header and Details rows back into a final table so I can then do more processing such as split each header and detail rows into their own txt files, etc....I don't need to go into details why but just know that this is the goal, therefore I need to relate each header row with their corresponding detail rows that are split off into a MaintenanceRow and PaymentRowTable

Smarter Table Build - Might Split The Table
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.

Merge Data From Two Tables Into One Table - No Updates/only Insert
Hi all,, I posted the questions in sql forum and got good sql statement to work with it.. However, I want to see if there is a way to do it in SSIS.. May be this is really basic questions but I am having hard time to do it in sql server 2005 SSIS.. I have a flat file that I want to merge with table in SQL server 2005. 1> I have successfully created a data flow task to import data from flat file to Table X (new table I created for this package). Now here is my question. I have a Table A already in the database with the same column structure as of TableX (Both the tables have 20 columns/same Name/Same design). I want to merge Table A and Table X and stored the data in TableA. However, I just don't want to merge blindly, I need to insert a new row in Table A only if the same row does not exist in Table A (there is no primary key, i am looking certain fields to see if the rows are same).. Here is an example: Table A -------------- 1 test test1 test2 test3 test4 test5 2 test test6 test7 test8 test9 test10 Table X ------------ 1 test test1 test2 test99 test4 test5 2 test test98 test97 test 96 test95 test94 -------------------------------------------------------- Now, I want to only insert row 2 of Table X since there is match on 4 of the fields in row1.. The new Table A should look like NEW Table A' ----------------- test test1 test2 test3 test4 test5 test test6 test7 test8 test9 test10 test test98 test97 test 96 test95 test94 ------------------------------------ I think, I could do this using Execute SQL task and write all the code in sql, but that will be cumbersome and time consuming.. Is there a simpler way to achieve this? Thanks in advance.

Should I Split This 175 Million Record Table?
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

Read The Filename, Split It And Put It In A Table
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! Worf

How To Split Cells In A Table Format
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 Sonny

Data Flow Split
I'm trying to figure out how in a Data Flow Transform I can split some data. I have data coming through that has a PK (col1) and datetime col (col2). This data may contain multiple rows for the PK, col1. I want to be able to take the min datetime for each row for col1 and send down one path and all other rows down another path eg. There are 20 rows in the Data Flow coming through. Col1 has value 1 for first 10 rows, value 2 for remaining 10 rows and there are different values for Col2 for all rows. Take the Min value in Col2, where col1=1 and also the min value in Col2, where col1=2 and send down one path. Send all other rows down another path. I thought of using the Conditional Split Transform but my Expression knowledge isin't experienced enough (I'm looking into this) and I'm not sure if it can be done. I also though of using the Multi-Cast Transform and then using the Aggregate function, on each data set. While I can do this easily for the first data flow. SELECT col1, MIN(col2) FROM tbl1 GROUP BY col1 which is easily done in the Aggregate transform, the other side of the data flow I can't see how can be done using the Aggregate Transform SELECT col1 FROM tbl1 WHERE col2 NOT IN (SELECT MIN(col2) FROM tbl1 GROUP BY col1). Are either methods feasilble or is there another way. I want to avoid putting this data into temp tables in a SQL database and manipulating the data from there. The data has been extracted from a flat file source. Any help and ideas welcome.

Join Two Tables And Only Return The Latest Data For The Child Table
I have two table, tblCharge and tblSentence, for each charge, there are one or more sentences, if I join the two tables together using ChargeID such as: select * from tblCharge c join tblSentence s on c.ChargeID=s.ChargeID , all the sentences for each charge are returned. There is a field called DateCreated in tblSentence, I only want the latest sentence for each charge returned, how can I do this? I tried to create a function to get the latest sentence for a chargeID like the following: select * from tblCharge c join tblSentence s on s.SentenceID=LatestSentenceID(c.ChargeID) but it runs very slow, any idea to improve it? thanks,

Comparing A Column List Split To A Table.
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. Make any sense? So,what I need to do is separate the list of answers and say :select member_id from profile_answers whereANY ANSWER in function_to_split(answer) MATCHES ANY OF THESE (selectvalu from dbo.iter_intlist...It seems I might have to join or something, I am just a little lostright now.Here is my proc.ALTER procedure search_detailed_get_ids@question_id as integer,@answers as varchar(8000),@member_ids ntextasdeclare @v as varchar(8000)--get the delimited string of all possible answersset @v = (select bind_data from profiles_questions where question_id =@question_id)--prepare it for the function only accepting 1 charset @v = replace(@v, '||', '|')--gimme all members that matchselect member_id from profiles_answers where question_id = @question_idand answer in(select valu from dbo.iter_intlist_to_table(@v, '|') where listpos in(select valu from dbo.iter_intlist_to_table(@answers, ',')))and member_id in (select valu from dbo.iter_intlist_to_table(@member_ids, ','))returngo

SQL View To Split Rows In Single Table...
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?

How To Split Data From The MS SQL 2000 Database?
Hi All, We are working on a project, (C#.Net 2003, MS SQL 2000) where database is growing as 2 to 3 GB per day (Scanned Documents are storing in Database). There is only one table in the database. Currently database size is grown upto 200 GB. For safety reason we are planning to split the database accoring to one key field in the table say Book_no. Please guide/suggest me how to split the database now on the SQL query like "SELECT * FROM master_records WHERE book_no=1" And later how to merge/combine all these splitted database into one. I thought of using "Data Export" and later "Import with Append" but don't know whethere it will effective or not? Any method or tool available to Split the database table and later combine them to make again a single one? Please help me, its urgent. Thanks in advance.

Loading Data From Same Table (oracle) In To Diff SQL Tables With In Same Package(same Query)
Hi, I have Table A . we already have 80 columns . we have to add 65 more columns. we are populating this table from oracle .and we need to populate those 65 columns again from the same table. Is it a better idea to add those new 65 columns to the same table or new table. If we go for the same table then loading time will be double, If I go for new table and If i am able to run both the packages which loads table data from same oracle server to difffrent sql tables then we should be good. But if we run in to temp space issues on oracle server . Then i have to load the two tables separately which consumes the same time as earlier one. I was thinking if there is a way in SSIS where I can pull data from same oracle table in to two diff sql tables at same time?

Split Wide, Denormalized Table Into Normalized Structure
Thanks for reading. 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. Thanks again... simplified example (my source files and denormalized tables are 20 - 30 colums wide) Excel or flat file (_FF_): =================== name, address, city, state, cellphone, homephone Denormalized table (_DNT_): =================== name, address, city, state, cellphone, homephone normalized tables (_NT_): ================== tblPerson [PK_person, name, age, height, weight] tblAddress [PK_address, FK_person, street, city, state, zip, addressType] tblContact [PK_contact, FK_person, data, contactType] Process: ========= (1) _FF_myExcelFile.xls --> DTS --> _DNT_myWideTable (2) _DNT_myWideTable --> storedProcs --> _NT_tblPerson, _NT_tblAddress, etc... Step 2 details: ================ 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 INSERT INTO tblPerson (name) VALUES (@name) SET @personID = @@IDENTITY END

How To Split A Transaction Table To Create Training And Testing Set For AR
Hi all, 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. Fakhrul
