T-SQL (SS2K8) :: Add A New Column To Dataset At Runtime That Tallies Whenever Condition Arises
Nov 3, 2014
I am trying to find a way to provide three metrics for a table that only provides 2 of them. I need to derive a third column which tallies based on conditions that can be found in the dataset.
The table I'm querying shows
(1) total referrals
(2) total moves
but it is missing a column that tallies whenever the referral moved into the same property_id that it was referred to.
create table dimFacts
(date_value datetime
, month_name varchar(9)
, year_number varchar(4)
, month_number tinyint
[Code] ....
How can I use sql to create one additional column for the above data set, ie. let's call it 'property_conversion' such that on the fifth row there will be a '1' showing that on 2012-12-30 lead_id 10038655 moved into the property it was referred to back on 2012-10-15 ?

Table A - data example
Idno Entity Flag
1 1 y
2 1 n
3 1 y
4 1 y
Table B - data example
Idno Entity
1 1
2 1
3 1
Table C - data example
Idno Entity
4 1
I want to update the value flag in table A.Update flag from n to y if idno A in table B and and idno A not in table C, so from table A above, first record and 3rd record remain unchange but 2nd record, flag will be changed from n to y. 4th record where idno A not in table b and in Table C so flag will change from y to n. is it possible, or do i need to use the "fetch" method to compare record by record.

I am currently in the process of writing an INSERT/UPDATE trigger in SQL 2012, the scenario is, I have a table called Quote, what I want to happen is when a record gets added to the table with a field called Approved, populated with a value or a record gets Updated and the Approved field gets populated I want the trigger to execute a stored procedure, passing through a value from a field called Account within the Quote table as a variable. I know I can achieve the action using one trigger "AFTER INSERT, UPDATE" but I am struggling on forming the rest of the trigger.

I have around 3 tables having around 20 to 30gb of data. My table A related to table B by a FK and same way table B related to table C by FK. I would like to delete all rows satisfying certain condition from table A and all corresponding related records from table B and C. I have created a query to delete the grandchild first, followed by child table and finally parent. I have used inner join in my delete query. As you all know, inner join delete operations, are going to be extremely resource Intensive especially on bigger tables.
What is the best approach to delete all these rows? There are many constraints, triggers on these tables. Also, there might be some FK relations to other tables as well.

I want to change Set clause of Update Statement dynamically based on some condition.
Basically i have 2 Update statments having same FROM clause and same JOIN clause.
Only diff is SET clause and 1 Where condition.
So i am trying to combine 2 Update statements into 1 and trying to avoid visit to same table twice.
Update t
Set CASE **WHEN Isnull(td.IsPosted, 0) = 0
THEN t.AODYD = td.ODYD**
*ELSE t.DAODYD = td.ODYD*
END
From #ReportData As t
Join @CIR AS tmp On t.RowId = tmp.Max_RowId
[Code] ....
But CASE statement is not working...

Imagine the following scenario: two tables (say, "requests" and "details") are joined in a 1:n relationship on MSSQL 2008. Both tables contain an ID (autoincrement field) and a timestamp field for proper concurrency management. Data access in the frontend is provided by a typed dataset in VS 2010. There are SPs on the server which select, update, insert or delete data in each of the two tables (so, 8 SPs alltogether: uspRequestsSelect, uspDetailsInsert etc.). These SPs are used for data access in the dataset. The GUI is a Windows form with 2 datagridviews, one for request datatable and one for the child-relation-based datatable FK_request_details. So, each request shows its details. The form works well so far.
Now, trouble strikes. A business rule says: "the first details row of a request (=row with lowest ID) always has a 0 in column "additional fee". For additional detail rows, this field has to be set to constant value 45". In short: the first detail row of each request is free, second and later details are charged 45 €.
So, I created a SP "uspRequestFeeManager", which recalculates all (!) detail rows of a request. This SP is called in uspDetailsInsert, uspDetailsUpdate and uspDetailsDelete, as each of this cases causes the additional fee to be recalculated for all rows (as rowcount can change). In Management Studio, this works as well!
But: as the uspRequestFeeManager changes data even for rows the user did NOT touch, there's a concurrency exception in my frontend in the following case:
In a request with 2 detail rows (first row has fee = 0, second = 45), the user deletes the row with fee = 0. Committing via TableAdapterManager calls uspDetailsDelete, which calls uspRequestFeeManager, which sets the remaining single details row to a fee value of 0 (which is correct!). This causes TableAdapterManager.UpdateAll to fail ("concurrency exception; delete command has handled 0 of 1 expected records"), as uspRequestFeeManager has "edited" a row which the user didn't touch, and thus updated its timestamp as well. So, the list is out of sync.
The uspRequestFeeManager looked like a good idea... but it seems not to be.
Approach would be: instead of calling the uspRequestFeeManager from within the SP, call it programmatically after TableAfterManager.UpdateAll, and after that, 're-fill' the details datatable with the updated data. But that would transfer business logic from server to client. I don't like that...

im working on a report which shows the data based on the users input. I have used a matrix because I have no control on how many fields the users want, so practically we have a dynamic column here. My problem is that they require me to able the user to hide the columns he/she wishes to during runtime. We have a previous report that enables the user to hide it during runtime but it has static column. Any idea on how I could do it?... Thank you so much...

Hi -- I am fairly new to SSIS development, although I am starting to appreciate it more an more, especially since I have started getting into extending the object model. Here's my question:
I have a data flow that pulls data from any number of different delimited files with different numbers of columns. I have had no problem dealing with setting up run-time file locations and file names by using the expressions of a flat file data source, and i have been able to pretty easily deal with varying file delimiters by standardizing the files before they get into the data flow. however, I have not been able to come up with a solution that will allow my data source to discover its column info at run time, and then pass that information on to the data flow task. all i really care about is being able to properly parse the individual rows into individual column data by the flat file data source because the data flow itself is able to discover the actual data that the columns hold at run-time.
i would very much appreciate any feedback from anyone on possible solutions for this.
thanks!

I have a table called names (firstname, lastname, number) then i have a DECLARED variable called @displaynum...If @displaynum id true my select query should select the number column. if the variable is false , only the first two columns are selected.
e.g @displaynum = true
@displaynum = false
Firstname | Lastname | number Firstname | Lastnam
blah | blah | 12345
blah | blah
i am not sure if this is possible as a case still selects the column but just changes the values.

I've found that there is no such thing as a Case Statement in the Derived Column task in the data flow objects. I've written a ternary statement instead. I can't seem to get it to work exactly how I want it to. For example
AccountCategory == "E" ? 1 : 2
Works fine but the following doesn't
AccountCategory == "E" ? CreditAmount : DebitAmount
The CreditAmount and DebitAmount Fields are spelled correctly, the field type of AccountCategory is String and the Field type of CreditAmount and DebitAmount is numeric, but that seems to be the same situation that I have in the first example that works. Am I missing something? I'd appreciate any advice anyone has to offer. Thanks,
Bill

We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change
DECLARE@size varchar(5)--The new size of the column
DECLARE @TSQL varchar(255)--Contains the code to be executed
DECLARE @Object varchar(50)--Holds the name of the table
DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10)
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1
Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.

Hello all. I hope someone can offer me some help. I'm trying to construct a SQL statement that will be run on a Dataset that I have. The trick is that there are many conditions that can apply. I'll describe my situation:
I have about 1700 records in a datatable titled "AISC_Shapes_Table" with 49 columns. What I would like to do is allow the user of my VB application to 'create' a custom query (i.e. advanced search). For now, I'll just discuss two columns; The Section Label titled "AISC_MANUAL_LABEL" and the Weight column "W". The data appears in the following manner:
(AISC_Shapes_Table)
AISC_MANUAL_LABEL W
W44x300 300
W42x200 200
(and so on)
WT22x150 150
WT21x100 100
(and so on)
MT12.5x12.4 12.4
MT12x10 10
(etc.)
I have a listbox which users can select MULTIPLE "Manual Labels" or shapes. They then select a property (W for weight, in this case) and a limitation (greater than a value, less than a value, or between two values). From all this, I create a custom Query string or filter to apply to my BindingSource.Filter method. However I have to use the % wildcard to deal with exceptions. If the user only wants W shapes, I use "...LIKE 'W%'" and "...NOT LIKE 'WT%" to be sure to select ONLY W shapes and no WT's. The problems arises, however, when the user wants multiple shapes in general. If I want to select all the "AISC_MANUAL_LABEL" values with W <= 40, I can't do it. An example of a statement I tried to use to select WT% Labels and MT% labels with weight (W)<=100 is:
Code SnippetSELECT AISC_MANUAL_LABEL, W
FROM AISC_Shape_Table
WHERE (W <= 100) AND ((AISC_MANUAL_LABEL LIKE 'MT%') AND (AISC_MANUAL_LABEL LIKE 'WT%'))
It returns a NULL value to me, which i know is NOT because no such values exist. So, I further investigated and tried to use a subquery seeing if IN, ANY, or ALL would work, but to no avail. Can anyone offer up any suggestions? I know that if I can get an example of ONE of them to work, then I'll easily be able to apply it to all of my cases. Otherwise, am I just going about this the hard way or is it even possible? Please, ANY suggestions will help. Thank you in advance.
Regards,
Steve G.

I have a script that loops through a series of tables to send data to a table from each of the tables. My issue is that not all tables have the columns I need in them. What I would like is to replace the column with another column when it does not exist. Something like below
Select Misisng_Column(A.Name, replace with B.Name) as Name
FROM SomeTable A
Cross Join (Select Name FROM AnotherTable) B
AnotherTable has one record in it. To avoid a Cartesian issue. Like I said just an example
In my real script the table aliased as A is from a list of tables in a sys.tables query that loops through to the end.
