MS SQL Server :: Data Manipulation With One-to-many-to-one Relationship

Exported Flat File Data Will Not Import To Same Table Without Extensive Data-type Manipulation

Jul 13, 2007

I'm moving data between identical tables and have to use a flat file as an intermediary. I thought: "No problem, SSIS can do a quick export to a file, then move the file to another server, then use SSIS to import the data to the new server."

Seems simple, right?

I'm hitting all sorts of surprising data conversion errors. I used the export wizard to create the export package. This works fine. However using the same flat file definition, the import package fails -- even when I have no destination. That is I have just one data flow task that contains only one control: the Flat File source. When I run the package the flat file definition fails with data type conversion and truncation errors. One of the obvious errors is for boolean types. The SQL field is a bit, SSIS defined the column as DT_BOOL, the output of the data are literal text values "TRUE" and "FALSE". So SSIS converts a sql datatype of bit to "TRUE" and "FALSE" on export, but can't make the reverse conversion on import?

Does anyone else find this surprising? I would expect that what SSIS exports, it can import given all the same table and flat file definitions. Is SSIS the wrong tool to do such simple bulk copies? I'd like to avoid using BCP because this process will need to run automatically within SQL Agent so we can leverage all the error tracking and system monitoring.

Data Manipulation

Dec 26, 2007

Hello,

I have to perform some data manipulation based on ID1, ID2 with respect to Effective dates (below represented as effdt)
Source Code:

create table #source (id1 int, id2 int, effdt datetime)
insert into #source values (111, 123, '1/1/2007')
insert into #source values (111, 123, '3/1/2007')
insert into #source values (111, 123, '4/1/2007')
insert into #source values (111, 124, '5/1/2007')
insert into #source values (111, 125, '6/1/2007')
insert into #source values (111, 123, '7/1/2007')

Source Code Data:

ID1 ID2 Effdt
111 123 1/1/2007
111 123 3/1/2007
111 123 4/1/2007
111 124 5/1/2007
111 125 6/1/2007
111 123 7/1/2007

Target Data should look like:

ID1 ID2 Effdt Expdt
111 123 1/1/2007 4/30/2007
111 124 5/1/2007 5/31/2007
111 125 6/1/2007 6/30/2007
111 123 7/1/2007 7/31/2007

The logic is like the min(effdt) as effdt, min(effdt) - 1 as expdt of the next id2 from the source. Nut the problem comes when the same ID2 comes later after a different id2, so just a group by on id1, id2 does not suffice.
If it is the last record then the expdt is that month's end date.
Can someone throw me some light on what kind of logic I should be using to accomplish this.

Thanks in advance.
Greg

Gurus - How To Do Date Manipulation With Datetime Data

Mar 13, 2001

Hello,

I'm trying to use SQL for data warehousing using dates for manipulating data. As SQL doesnt have date, just timedate, and if I want to compare 2 dates to obtain someones age ( ie date - date of birth = age ) I have to use a TIMEDIFF or equivelent. This is REALLY annoying. Is there anyway to use just dates without having to code extra?

Does SQL ignore the time part of a datetime column - ie can I just do a date manipulation without concerning myself with the time ( assuming the time is NOT default at 00:00:00 for every entry ) or am I stuck with treating the field as a complete datetime? It may seem a dumbass question, but as I have to do a lot of date manipulations, it is essential to know.

Many thanks,

Warwick.

T-SQL (SS2K8) :: String Manipulation - Data Between Quotes

Apr 9, 2015

I have data in a trace file, and I need to extract some info such as phone number.The problem is the phone number could be varying lengths, and various positions in the row.

For example:

@City='New York', @Phone='2035551212' (10 characters, no dashes)
or
@City='San Francisco', @Phone='918-555-1212' (12 characters, with dashes)
or
@City+'Berlin', @Phone='55-123456-7890' (14 characters, with dashes)

I can use CHARINDEX to search & find @Phone=' so I know where the phone number starts, but stuck on a programatic way to find the data between the quotes since it can vary.

Moving Data To And From SQL Server 2005, With Manipulation In C#

Oct 9, 2006

Hi

I am wishing to
* take a table of data into a C# CLR procedure and store it in an array
* take a second table of data into this procedure row by row, and return a row (into a third table) for each row (and this returned row is based on the data in the array and the data in this row).

I am new to CLR programming, and pulling my hair out at the moment. I��m sure that what I��m trying to do is simple, but I am not making any progress with the on-line help and error messages L. I have now described what I am trying to do in more detail, firstly in English, and then in a T-SQL implementation that works (for this simple example). I��m looking for the C# CLR code to be returned �� containing preferably two parts:
* the C# code and
* the CLR code to ��make it live��
Since I am not sure where my coding is going wrong. (I think it should be possible to read in the one table, and then loop through thte second table, calculating and returning the necessary output as you do the calculations...

Problem in English
Consider a situation where there are three tables: DATATABLE, PARAMETERTABLE and RESULTSTABLE.

For each row in PARAMETERTABLE, I will calculate a row for RESULTSTABLE based on calculations involving all the entries form DATATABLE.

I am wishing to do this in a C# CLR for performance reasons, and because the functions I will be using will be significantly more complex, and recursively built up.

Consider the following table structures
DATATABLE �� [i int, datavalue real]
[1,12.5]
[2.10]
[3.14]
[4,17.5]
(where numberofrows is 4)
PARAMETERTABLE [parametera real, paramaterb real]
[10,2]
[11.7,1.1]
RESULTSTABLE [resultvalue real]
[20.5]
[18.26]

The values of the results table are calculated as the
sum (for i = 1 to numberofrows)
of
(Parameter1+i*parameterb-datavalue)^2
Which leads to the values shown.

T-SQL Implementation

-- Set up database and tables to use in example

USE master
GO

CREATE DATABASE QuestionDatabase
GO

sp_configure 'clr enabled', 1
GO

USE QuestionDatabase
GO

RECONFIGURE
GO

CREATE TABLE DataTable (i INT NOT NULL, DataValue REAL NOT NULL)
GO

CREATE TABLE ParameterTable (ParameterNumber INT NOT NULL, ParameterA REAL NOT NULL, ParameterB REAL NOT NULL)
GO

CREATE TABLE ResultsTable (ParameterNumber INT NOT NULL, ResultsValue REAL NOT NULL)
GO

--Initialise the Tables

INSERT INTO DataTable (i, DataValue) VALUES (1,12.5)
INSERT INTO DataTable (i, DataValue) VALUES (2,10)
INSERT INTO DataTable (i, DataValue) VALUES (3,14)
INSERT INTO DataTable (i, DataValue) VALUES (4,17.5)

INSERT INTO ParameterTable (ParameterNumber, ParameterA, ParameterB) VALUES (1, 10, 2)
INSERT INTO ParameterTable (ParameterNumber, ParameterA, ParameterB) VALUES (2, 11.7, 1.1)

-- The TSQL to be rewritten in C#, to produce the Output as hoped

INSERT INTO ResultsTable (ParameterNumber, ResultsValue)
SELECT ParameterNumber, SUM((parametera+i*parameterb-datavalue)*(parametera+i*parameterb-datavalue)) AS b
FROM DataTable
CROSS JOIN
ParameterTable
GROUP BY ParameterNumber

-- Output as hoped

SELECT * FROM DataTable
SELECT * FROM ParameterTable
SELECT * FROM ResultsTable

-- which produced

1 12.5
2 10
3 14
4 17.5

1 10 2
2 11.7 1.1

1 20.5
2 18.26

-- but I hope to do the same with something like:

CREATE ASSEMBLY *** FROM 'C:***.dll'

CREATE PROCEDURE GenerateResultsInCLR(@i int, @r1 real, @r2 real)
RETURNS TABLE (i int, r real)
EXTERNAL NAME ***.***.***

EXEC GenerateResultsInCLR

This is a simple example, that can be easily written in T-SQL. I am looking to develop things that are recursive in nature, which makes them unsuited to T-SQL, unless one is using cursors, but this becomes very slow when the parameter table has 1m records, and the data table 100k records. This is why the datatable must be read in once, and manipulated many times, and the manipulation will need to be in the form of a loop.

Thanks very much for your help.

Go well

Greg

Master Data Services :: User Friendly Way To Manage Data With Many-to-many Relationship

Sep 28, 2015

I've been quite excited about SQL Server MDS that should allow non-IT staff to easily maintain data. However maintaining data that have many-to-many relationships seems to be quite a pain. I believe the best way is:

Open up your MDS web interfaceGo to entities > product (for example)Add a new member and fill the details Click "product parts" in the bottom right "Related Entities" partAdd a new memberTry and find the product you just created from the dropdownlistSelect the first part and click OKAgain try and find the product you have created from the dropdownlistSelect the second part and click OKRepeat...Close the tab on your browser and finish your product entity.How I wish it worked:

Open up your MDS web interfaceGo to entities > product (for example)Add a new member and fill the detailsCheck a checkbox for each part visible under "product parts" in the bottom right "Related Entities" partFinish your product entity.

How Can I Create A One-to-one Relationship In A SQL Server Management Studio Express Relationship Diagram?

Mar 25, 2006

How can I create a one-to-one relationship in a SQL Server Management Studio Express Relationship diagram?

For example:
I have 2 tables, tbl1 and tbl2.

tbl1 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}

tbl2 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl1_id {uniqueidentifier} as FK linked to tbl1.id

If I drag and drop the tbl1.id column to tbl2 I end up with a one-to-many relationship. How do I create a one-to-one relationship instead?

Power Pivot :: Use Relationship Not Overriding Conflicting Active Relationship?

Oct 14, 2015

I have four tables with relationships as shown. They have a circular relationship and so one of the relationships is forced to be inactive.

   Operation (Commodity, OperationKey)   ==========>
Commodity (Commodity)
                      /
/
                       |
|
   Advice (OperationKey)       ====== (inactive)=======>
Operation Commmodity (Commodity, OperationKey)

I have the following measure:

Advice No. Commodity:=CALCULATE (
COUNTROWS ( 'Advice' ),
USERELATIONSHIP(Advice[OperationKey],'Operation Commodity'[OperationKey]),
operation
)

However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.

If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.

How To Add Data Into A PK To FK Relationship?

Jan 7, 2008

HiI have 2 tables one is called QuickLinks and another called QuickLinkItemsQuickLinksQuickLinkID<PK> UserID QuickLinkName-------------------------- ----------- ------------------------1 111-111-111-111 QuickLink12 111-111-111-111 QuickLink23 222-222-222-222 QuickLink1 QuickLinkItemsQuickLinkID <FK> CharacterName CharacterImagePath---------------------- ------------------------------- ---------------------------------------- 1 a path11 b path22 d path32 e path43 a path14 b path 2 So thats how I see the data will look like in both of these tables the problem however I don't know how to write this into Ado.net code. Like I have made a PK to FK relationship on QuickLinkID(through the relationship builder thing). I am just not sure how to I do this. For the sake of an example say you have 5 text boxes 2 text boxes for inserting the character names and 2 text boxes for inserting the CharacterImagePath. Then one for the Name of the QuickLink. So how would this be done? Like if it was one table it would be just some Insert commands. Like if this was all one table I would first get the userID from the asp membership table then grab all the values from the textBoxes and insert them where they go to and the QuickLinkID would get filled automatically. The thing that throws me off is the QuickLinkID since it needs to be the same ID as in the QuickLink table. So do I have to first insert some values into the QuickLink table then do a select on it and grab the ID then finally continue with the inserts Into the QuickLinkItems table? Or do I have to join these tables together?Thanks

How Can I Populate Data In A One-to-one Relationship

Jul 20, 2006

Here is what I have and (somewhat understand). I’m using Visual Web
Developer 2005 Express Edition and have setup my application to use form authentication
(which automatically creates the ASPNETDB.MDF file with several default tables
and views). I’m using the CreateUserWizard
which is fine…but I need to collect additional information like (firstname,
lastname, address…and on..). What I’ve
done. I’ve created a tabled named
UserProfile and set UserId as the primary key (uniqueidentifier).
I then setup a 1-to-1 relationship
between aspnet_Users and UserProfile (which I think is correct). On my UpdateContactInfo.aspx page (where
users go to update their personal information) I use a hidden label control
(UserValue) to receive the UserId during the page_load event as below:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load UserValue.Text = Membership.GetUser().ProviderUserKey().ToString() End Sub Now with the UserID available I need to populate the
UserProfile table with the UserId, firstname, lastname, address of the
currently logged in user. How can I do this and am I on the
right track..?

Inserting Data Into Two Tables With Parent-child Relationship

Nov 13, 2006

I am trying to insert data into two tables with a SSIS package. One table has a foreign key relationship to the other table's primary key. When I try to run the package, the package will just seems to hang up in bids. I have found two ways around the issue but I don't like either approach. Is there a way to set which table gets insert first?

If I uncheck the check constraints option on the child table, the package will run very quickly but this option alters the child table and basically disables the constraint. I don't like this option because it is altering the database.

The second approach is to set the commit level on both tables to say 10,000 and make sure that the multicast component has the first output path moved to the parent table. I don't like this option because I am not sure if the records are backed out if the package should abend after records have been committed.

Integration Services :: Loading Data To Destination With Foreign Key Relationship

Apr 22, 2015

I have to load data into destination table, it has foreign key relation to two different tables called person table and organization table . sample data to be loaded is like

person_id organization_id

2                    NULL
Null                1
null               null

person table and organization table doesn't have null values in them, when I try to load this data none of them are laoded, I know either person_id or organization id having null value is failing foreign key constraint. But I want to transfer all the rows except the ones having both nulls. how this can be achieved ?

Dataset Manipulation

Mar 1, 2007

Have an XML file that i load in to a Dataset. works fine, it builds its own scheme perfectly.
I loop through that data to load a check list which also works wonderfully.
two questions based on that.
1) can i add a column after the fact? I want to basically update the the info in the dataset to store if the record was checked in the check list. if not, i can manipulate one of the already defined columns, but i would rather not.
2) what is the best way to update data with in the dataset? Never really done anything but pull data from one. how do i locate the correct row to update ("select name from tbl where name = " + checklist.items[index].tostring(); update row)

sorry for the fairly basic question. i appreciate the help.

String Manipulation ?

Nov 30, 2004

I was given a script that was supposed to take a name field that was separated by commas and normalize it into last, first and middle name. My data looks like below in one fieldname called longname

crab,mike,Allen
Lota Weilly,Eric,M

My script to do this looks like

update ailoca
set last_name = substring (longname, 1, patindex( '%,%' , longname) -1 ),
first_name = substring (longname, patindex( '%,%' , longname) + 1, patindex( '% %', longname)-patindex( '%,%' , longname)),
middle_name = substring (longname, patindex( '% %', longname) + 1, len(longname)-patindex( '%,%' , longname))

My problem is that some people actually have 2 last names, not hyphenated, but 2. Whenever I have 2 names I get the following error

Server: Msg 536, Level 16, State 3, Line 1
Invalid length parameter passed to the substring function.
The statement has been terminated.

It seems to be related to the first name, I can comment out that update and it works

Thanks
Thanks

Text Manipulation

Apr 30, 2008

Hi, is there a way i can replace multiple white spaces & tabs into one , on a TEXT column ?

I am using replace function and trying to store the result into a varchar variable and the TEXT being truncated after 255 charecters.

for example, I tried this :

declare @str varchar(4000)
select @str = replace(cast(textcolumn as varchar(4000)), ' ', NULL)

I understand t-SQL dml statement(s)
will automatically truncate after 255 chars in a long string. But, seeking for other options here pls.

thanks for ur help..
