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.
I'm trying to read the filename from a file that I'm downloading by FTP (FTP Component) into a string variable so I can later use it for another part of the process, how can I do this?
Right now I have a web page that when you click on the only button on the page it opens a text file, reads a line from the text file, splits the comma separated line and stores it in to an array 'strData' and then moves on to the next line and repeats this process.What I want to do before it goes to the next line is insert that strData in to a SQL DB.This is my InsertCommand for my SqlDataSource1:InsertCommand="INSERT INTO [Numbers] ([WTN], [DSL_Qualified], [DSL_Qualified_Date], [Equip_1MM], [Line_Trouble], [Sync_Rate], [Res_Bus], [Host_Remote]) VALUES (@WTN, @DSL_Qualified, @DSL_Qualified_Date, @Equip_1MM, @Line_Trouble, @Sync_Rate, @Res_Bus, @Host_Remote)"Plus the <InsertParameters>:<InsertParameters> <asp:Parameter Name="WTN" Type="Int32" /> <asp:Parameter Name="DSL_Qualified" Type="String" /> <asp:Parameter Name="DSL_Qualified_Date" Type="DateTime" /> <asp:Parameter Name="Equip_1MM" Type="String" /> <asp:Parameter Name="Line_Trouble" Type="String" /> <asp:Parameter Name="Sync_Rate" Type="String" /> <asp:Parameter Name="Res_Bus" Type="String" /> <asp:Parameter Name="Host_Remote" Type="String" /> </InsertParameters>So I'm not sure exactly what to do after this:while (file.Peek() > -1) { string strCSVData = file.ReadLine(); string [] strData = strCSVData.Split(','); // somehow get strData in to the SqlDataSource1.Insert method?? }Any help would be appreciated.Thanks.
Scenario Configuration : VB.net 2005 Code, WebService for Executing SSIS on Server, SSIS deployed on the Database Server
Problem Description : We are developing windows applicaiton in which we call webservice which was deployed on the same server where SSIS packages are deployed. Now from Code we are passing FilePath name in variable and execute the Package. But the SSis result says that The file name "\computernamefol1fol2fol3fol4abc.txt" specified in the connection was not valid.
More Information:
1. Full Permission are given on this network folder. 2. Package executes successfully from SSIS development solution (BIS solution) 3. Deployed packed executes successfully from the Database Server. 4. From Development pc packege executes successfully. 5. Other packages deployed on the same server executed suucessfully with same configuration and scenario.
Only this package is not executing.
-- the only differece with this package with other is -
using ".txt" extension in Flat file connection and using VB Script task
Can any one suggest the appropirate solution for this problem...
I am loading files with same format from two different locations in to one database. First, my SSIS connects to location 1.
Lets Say Location1 : C:LoadFilesImport Location2 : D:LoadFilesImport
Location one has three different set files starting with
First Set: AP_1, AP_2,AP_3, Second Set: VD_1, VD_2, VD_3, Third Set: BK_1,BK_2,BK_3,
This SSIS set to run every 3 hours, if it finds files of any set load them. While loading it has to insert into a derivedcolumn called CustID. If the file name Starts with AP_ , custiD values should be as 101
AP_1 goes to Table1 AP_2 goes to Table2 AP_3 goes to Table3
If the file name Starts with VD_ , custiD values should be as 201 If the file name Starts with BK_ , custiD values should be as 301
after processing all these files in first location, the SSIS looks for files in second location and does the same?
--How to achieve CustID depending upon file name ?
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);
Any easy way for a batch file or automated process to read from one db and table and what ever entry is missing out of another database + table it writes those missing entries to.
This is a simple table in one db that is filled with usernames, I want to see if there are missing usernames in another db and table and write those entries.
db1.usr_table.usr_name = jdoenew If jdoenew is missing in the 2nd db I will need to write entries like: db1.usr_table.usr_name = jdoenew db1.usr_table.password = tmppassword db1.usr_table.active = 1
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?
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.
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,
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.
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
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.
number_row fld_index vtext ---------------------------------------- 1 101 a 2 101 b 3 101 c 4 102 d 5 102 e 6 102 f 7 103 g 8 103 h 9 103 i ...... ...... .... now i need to do this
SELECT fld_index FROM table_index GROUP BY fld_index
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.
I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A: (name phone house cost of house,zipcodecountystatecountry) -a view will later split this large varchar string based column b: is the source filename of the data load (varchar 256) ....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?
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).
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
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:
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:
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.
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
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')
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.
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
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.
