My company use SQL server 2005 standard. considering deal with huge data, how if we want to split data (date range yearly or monthly) in order to ease transaction. that's simply for us to use query, but how if we want to split data that can be easily execute by operator (non-admin privilege). Is there any another way?

hai all,
This is my first question to this forum.
here is my situtation:
I am into report testing I need to test a report for which i have write a query,iam using qery analyser for runing query
Database : sql server
tabel name :job_allocations
column naME :technicain code
Based on techincain code in joballocation tablei need to get technician cost from other table for the particular technician.
Based on the technician code user chooses column will be updated
if single data will be TC01
if more than one then data will be TC01:TC02:TC03
user can choose any number of techincian for a job
MY problem is :How to split tha when there is multiple technician and calculate cost for the job
Ineed it in single excecution query
Table structure
job_allocation table
jobcardn_fk Technician_code
jc01 TC01
jc02 Tco1:Tco2:Tc03......
I need it in
jobcardno_fk TEchnician_code
jco1 Tc01

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.
I have a query that returns a table similar to:
State Status Count
CA Complete 10
CA Incomplete 200
NC Complete 20
NC Incomplete 205
SC Incomplete 50
What sort of query will allow me to reformat the table into:
State Complete Incomplete
CA 10 200
NC 20 205
SC NULL 50

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

hi all
i using SSIS to update data on tables based on another tables as follow

--distination table almost 3 million
my package execute from 2 days and still working till now updated 122,000 and insert 4 million

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.
Hi
This is probably a very basic question for most people in this group.
How do i split the data in a column in to 2 columns? This can be done in access with an update query but in MS SQL server I am not sure.
Here is an example of what i want to acheive
FName
John?Doe
FName LName
John Doe
thanks for the help

Hi,
I have a scenario, where I have a string column from database with value as "FTW*Christopher,Lawson|FTW*Bradley,James". In my report, I need to split this column at each " | " symbol and place each substring one below the other in one row of a report as shown below .
"FTW*Christopher,Lawson
FTW*Bradley,James"
Please let me know how can I acheive this?
I'm using sql 2008 and triying to build a dynamic sql script to split the records 50/50.I know using newid() with order by clause selects randomly but how should I build the select statement to split the data 50/50 so i don't need to run the script manually everytime ?

Basically, I have a Conditional Split. What I need to do is for each row coming out of my split, I need to SELECT some data from another database based on one of the fields and then place the data from the DB into a file for later processing.
Seems pretty simple, considering the power of SSIS. Using tools such as OLE DB Command didn't help - the data that comes out of the OLE DB Command is the input data, not the data returned by the command.
How can I do this?

OK, so I have:
- 500 GB DW
- 5 GB in smaller DBs
- 220 GB TempDB
- 350 GB in Log files.
My machine is Fujitsu Primergy 64 cores (with HT) and 192 GB RAM.
I have several IO locations:
- 540 GB in-server HDD 15k RAID10
- 1 TB HDD 15k RAID10 on SAN (separete controller)
- 2 TB HDD 15k RAID10 on SAN (same controlller as below)
- 800GB SSD RAID10 on SAN (same controller as above)
Data warehouse has 2 fact tables that are absolutely crucial and quite large.
Now i want to organize DB into several Filegroups and put them on different drives. Filegroups I'm thinking of:
- FILEGROUP1: for 1st crucial Fact Table
- FILEGROUP2: for 2nd crucial Fact Table
- FILEGROUP3: for tempDB
- FILEGROUP4: for dimensions data
- FILEGROUP5: for the rest of facts data
- FILEGROUP6: for dimensions indexes
- FILEGROUP7: for the rest of facts indexes
- FILEGROUP8: for 1 log file of one smaller DB (its in full-recovery and its quite large)
- FILEGROUP9: for the rest of log files
- FILEGROUP10: others
How should I organize them across available drives? I was thinking about sth like:
800 GB SSD: FILEGROUPS 1-3
2 TB RAID10: FILEGROUPS 5+7+8
1 TB RAID10: FILEGROUPS 4+6+10
540 GB in-server: FILEGROUP 9
I know that having multiple filegroups on the same drive is pointless regarding performance, but in future i could actually add some more drives, so i want to separate them now.
Also - how much files per filegroups should i create? Considering 1 or 2. Except TempDB where I am going for 4.
I have a field in a table that contains addresses e.g
15 Green Street
5F Brown Steet
127 Blue Street
1512 Red Road
I want to output the numbers into one column and the address to another column as i need to produce a report that only shows streets and roads but no numbers.
So basically no matter how many characters before the first space which can be numbers or letters i want these output into two columns.
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'm encountering a very peculiar situation when I'm trying to compare source and target data using conditional split. Following is the Data Flow and how I'm trying to achieve this.
Source Data : Col_A (PK)Â Â Â Â Â Col_2
                      1                   100
                      8                   500
Target Data : Col_A (PK)Â Â Â Â Â Col_2
                      1                   100
                      3                   700
                      8                   500
Look-up Target on Col_A to check for existing records. Now we have four columns in Look-up match output: Col_A, Col_B, Lkp_Col_A (Target Col), Lkp_Col_B (Target Col).
Conditional Split: Compare Col_B with Lkp_Col_B
Update target if there is any change in the existing value of Col_B.When I'm running the package for every record in source, the conditional split fails and even when there is no change in Col_B, some of the records (Not all and quite randomly) get updated with the same value. If I run the package for few records, it works absolutely fine.
I€™ve created with the help of some great people an SSIS 2005 package which does the follow so far:
1) Takes an incoming txt file. Example txt file: http://www.webfound.net/split.txt
The txt file going from top to bottom is sort of grouped like this
Header Row (designated by €˜HD€™)
Corresponding Detail Rows for the Header Row
€¦..
Next Header Row
Corresponding Detail Rows
€¦and so on
http://www.webfound.net/rows.jpg
2) Header Rows are split into one table, Maintenance Detail Rows into another, and Payment Detail Rows into a third table. A uniqueID has been created for each header and it€™s related detail rows to form a PK/FK relationship as there was non prior to the import, only the relation was in order of header / related rows below it when we first started. The reason I split this out is so I can massage it later with stored proc filters, whatever€¦
Now I€™m trying to somehow bring back the data in those table together like it was initially using a query so that I can cut out each of the Header / Detail Row sections into their own txt file. So, if you look at the original txt file, each new header and it€™s related detail rows (example of a cut piece would be http://www.webfound.net/rows.jpg) need to be cut out and put into their own separate txt file.
This is where I€™m stuck. How to create a query to combine it all back into an OLE DB Souce component, then somehow read that souce and split out the sections into their own individual txt files.
The filenames of the txt files will vary and be based on one of the column values already in the header table.
Here is a print screen of my package so far:
http://www.webfound.net/tasks.jpg
http://www.webfound.net/Import_MaintenanceFile_Task_components.jpg
http://www.webfound.net/DataFlow_Task_components.jpg
Let me know if you need more info. Examples of the actual data in the tables are here:
http://www.webfound.net/mnt_headerRows.txt
http://www.webfound.net/mnt_MaintenanceRows.txt
http://www.webfound.net/mnt_PaymentRows.txt
Here's a print screen of the table schema:
http://www.webfound.net/schema.jpg
I am importing the values for field Atype from a .csv file as DT_STR, 13 and I need to fit them into a bit type CType field.
When I write the conditional split ((ISNULL(Atype)?"a":Atype)!=(ISNULL(CType)?"9":CType)) it says that the DT_WSTR and DT_I4 types are incompatible and that I need to explicitly cast with a cast operator. I haven't been able to make it work, how to explicitly cast?
I have a delimited text file with 650+ columns. The sum of the column lengths of a single row, if fully populated, exceeds 30K bytes. The "killer" fields lengthwise are the "Description" fields. If they were removed from the input file, the remainig columns would occupy about 5000 bytes, which is within SQL max row length.Â
Can SSIS be used to created these two tables? (one without  description fields, the other with those field but arranged vertically in the table rows).
The fundamental issue is I can not import a single file row into a sql table because that row length could exceed the max byte count for a row.
Hi JayH (or anyone). Another week...a new set of problems. I obviously need to learn .net syntax, but because of project deadlines in converting from DTS to SSIS it is hard for me to stop and do that. So, if someone could help me some easy syntax, I would really appreciate it.
In DTS, there was a VBScript that copied a set of flat files from one directory to an archive directory after modifying the file name. In SSIS, the directory and archive directory will be specified in the config file. So, I need a .net script that retrieves a file, renames it and copies it to a different directory.

View 1 Replies View RelatedSo 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.
Quick question.
I've got a CHAR (70) field called NAME that has a first and last name separated by a space. I want to split it into two fields FIRST and LAST -- with all the characters to the left of the space a first name and all the characters to the right of the space as last name. I couldn't find a string function that would let me do this simply (it may be right in front of me and I missed it).
Thanks in advance.

I have a database with a "large" table containing date based information Basically they're reservations. I've thought about creating a new table and adding any records from past years to this table. For the most part only current reservation need to be searchable, but in some circumstances it would be useful to be able to search through the archive too. so, my questions!!!
Is 8,000 or so rows of data "large" and unwieldly in SQL terms?
Would splitting this data into 2 tables - one small table for current and future reservations and one larger archive table then using a UNION SELECT query to make archive information seachable be a significant improvment on server resources/load or am I making the whole thing more complicated than it need be as 8,000 rows of data is nothing to worry about.............
What did they say about a little bit of knowledge being a dangerous thing?
Thanks in advance of any guidance to a neophyte!!?

SQL UDF split()
The objective of this article is to help the SQL developers with an UDF that can be used within a stored procedures or Function to split a string (based on given delimiter) and extract the required portion of the string.
Scripting languages like VB script and Java script have in-built split() functions but there is no such function available in SQL server. In my experience this function is really handy when you’re working on an ASP application with SQL server as backend, whereby you’ll need to pass the ASP page submitted values to the SQL stored procedure.
To give a simple example, in a typical Monthly reporting ASP page – the users would select a range of months and extract the information pertaining to this date range. Classic implementation of this model is to have an ASP page to accept the input parameters and pass the values to the SQL stored procedure (SP). The SP would return a result set which is then formatted in the ASP page as results.
If the date range is continuous ie. JAN07 to MAR07 then the SP can typically accept a ‘From’ and ‘To’ range variables. But I’ve encountered situations whereby the users select 3 months from the current year and 2 months from previous year (non-continuous date ranges). In such scenario the SP cannot have a date range as input parameters.
Typically an ASP programmer would do is by having a single date input parameter in the SP and call the SP within a loop in the ASP page. This is an inefficient way of programming as contacting the database server within an ASP loop could cause performance overhead especially if the table being queried is an online transaction processing table.
Here is how I handled the above situation.
1.Declared one string input parameter of type varchar(8000) (if you’re using SQL 2005 then it is advisable to use Varchar(Max))
2.Pass the ASP submitted values as string, in this case the months selected by user would be supplied to the SP as a string
3.Within the Stored Procedure I’ll call the split() function to extract each month from the string and query the corresponding data
The basic structure of the stored procedure is as pasted below:-
CREATE PROCEDURE FETCH_SALES_DETAIL (
@MONTH VARCHAR(MAX)
)
AS
BEGIN
DECLARE @MONTH_CNT INT,@MTH DATETIME
SET @MONTH_CNT=1
WHILE DBO.SPLIT(@MONTH,',',@MONTH_CNT) <> ''
BEGIN
SET @MTH = CAST(DBO.SPLIT(@MONTH,',',@MONTH_CNT) AS DATETIME)
--<<Application specific T-SQLs>>-- (BEGIN)
SELECT [SALES_MONTH],[SALES_QTY],[PRODUCT_ID],[TRANSACTION_DATE]
FROM SALES (NLOCK)
WHERE [SALES_MONTH]= @MTH
--<<Application specific T-SQLs>>--(END)
SET @MONTH_CNT=@MONTH_CNT+1
END
END
Dbo.SPLIT() function takes 3 parameters
1)The main string with the values to be split
2)The delimiter
3)The Nth occurrence of the string to be returned
The functionality of the UDF is as explained STEP by STEP:
1.Function Declaration
CREATE FUNCTION [dbo].[SPLIT]
(
@nstring VARCHAR(MAX),
@deliminator nvarchar(10),
@index int
)
RETURNS VARCHAR(MAX)
Function is declared with 3 input parameters:-
@nstring of type VARCHAR(MAX) will hold the main string to be split
@deliminator of type NVARCHAR(10) will hold the delimiter
@index of type INT will hold the index of the string to be returned
2.Variable Declaration
DECLARE @position int
DECLARE @ustr VARCHAR(MAX)
DECLARE @pcnt int
Three variables are needed within the function. @position is an integer variable that will be used to traverse along the main string. @ustr will store the string to be returned and the @pcnt integer variable to check the index of the delimiter.
3.Variable initialization
SET @position = 1
SET @pcnt = 1
SELECT @ustr = ''
Initialize the variables
4.Main functionality
WHILE @position <= DATALENGTH(@nstring) and @pcnt <= @index
BEGIN
IF SUBSTRING(@nstring, @position, 1) <> @deliminator BEGIN
IF @pcnt = @index BEGIN
SET @ustr = @ustr + CAST(SUBSTRING(@nstring, @position, 1) AS nvarchar)
END
SET @position = @position + 1
END
ELSE BEGIN
SET @position = @position + 1
SET @pcnt = @pcnt + 1
END
END
4.1The main while loop is used to traverse through the main string until the word index is less than or equal to the index passed as input parameter.
4.2Within the while loop each character within the string is verified against the delimiter and if it does not match then local word count variable is checked against the input index parameter
4.3If the values are same ie., the input variable index and the word being processed in the while loop are the same then the word is stored in the @ustr variable. If the values does not match then the @position variable is incremented.
4.4If the character matches with the delimiter then the word count variable @pcnt is incremented along with the @position variable
5.Return the value
RETURN @ustr

I have 5 dynamic rows each row consisting of 5 checkboxes & 5 dropdowns.I am concatenating the values of each controls in a row using a wildcard charater "~" and each row i am concatenating using "|".The complete string is then assigned to one hidden field and passed as sql parameter to the backend.
Please help in writing the split function to get the values of each checkboxes and dropdowns from the string in order to save them in separate columns.
Thanks
