How To Reorder/compact A Column's Values After A Delete?
Feb 27, 2008
The business operation is this:
The data is stored and accessed by Invoice Number and Line Number. If there are 4 lines, 1,2,3,4 and number 2 is deleted the users want lines 3 and 4 reordered to be 2 and 3.
The existing code does things the following way, but I have my suspicions about how bulletproof it is:
Existing Data:
123,1
123,2
123,3
123,4
Begin Transaction
Delete where InvoiceNumber = 123 and LineNumber = 2.
Update set LineNumber=2 where InvoiceNumber=123 and LineNumber=3
Update set LineNumber=3 where InvoiceNumber=123 and LineNumber=4
Commit Transaction

I have a four tables called plandescription, plandetail and analysisdetail. The table plandescription has the columns DetailQuestionID which is the primary and identity column and a QuestionDescription column.
The table plandetail consists of the column PlanDetailID which the primary and identity column, DetailQuestionID which is the foreign key attribute of plandescription table and a planID column.
The third table analysisdetail consists of a analysisID which the primary and identity column, PlanDetailID which is the foreign key attribute of plandetail table and a scenario.
Below is the schema of the three tables
I have a two web form that will insert, update and delete data into these three tables in a two transaction. One web form will perform CRUD operations in plandescription and plandetail table. When the user inserts QuestionDescription and planid in this web form, I will insert the QuestionDescription Value in the plandescription table and will generate a DetailQuestionID value and this value is fed to the plandetail table with the planid. Here I will generate a PlanDetailID.
Once this transaction is done, I will show the second web form in which the user enters the scenario and this will be mapped with the plandescription using the PlanDetailID.
This schema cannot be changes as this is the client requirement. When I insert values I don’t have any problem. However when I update existing data, I need to delete existing PlanDetailID in the plandetail table and recreate PlanDetailID data for that DetailQuestionID and planID. This is because, the user will be adding or deleting a planID associated with the QuestionDescription.
Once I recreate PlanDetailID for that DetailQuestionID and planID, I need to update the old PlanDetailID with the new PlanDetailID in the third table analysisdetail for the associated analysisID.
I created a #Temp table called #DetailTable to insert the values analysisID, planid and old PlanDetailID and new PlanDetailID so that I can have them in update statement once I delete the data from plandetail table for that PlanDetailID.
Then I deleted the plandetailid from the plandetail table and recreate PlanDetailID for that DetailQuestionID. During my recreation I fetched the new PlanDetailID’s created into another temp table called #InsertedRows
After this I am running a while loop to update the temp table #DetailTable with the newly created PlanDetailID for the appropriate planID’s. The problem is here. When I have the same number of planID’s for example 2 planID’s 1,2 I will have only two old PlanDetailID and new PlanDetailID for that planID and analysisID.But When I add a new PlanID or remove a existing planID I am getting null value for that newly added or deleted planID. This is affecting my update statement of analysisdetail table as PlanDetailID cannot be null.
I tried to remove the Null value from the #DetailTable by running the update statement of analysis detail in a while loop however its not working.
DECLARE @categoryid INT = 8 DECLARE @DetailQuestionID INT = 1380 /*------- I need the query to run for the below three data. Here i'm updating my planids that already exists in my database*/ DECLARE @planids VARCHAR(MAX) = '2,4,5'
We have SharePoint list which has, say, two columns. Column A and Column B.
Column A can have three values - red, blue & green.
Column B can have four values - pen, marker, pencil & highlighter.
A typical view of list can be:
Column A - Column B red - pen red - pencil red - highlighter blue - marker blue - pencil green - pen green - highlighter red - pen blue - pencil blue - highlighter blue - pencil
We are looking to create a report from SharePoint List using SSRS which has following view:
red blue green pen 2 0 1 marker 0 1 0 pencil 1 3 0 highlighter 1 1 1
We tried Sum but not able to display in single row.
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.

Howdie y'all, Im adding rows to my database like this: GroupID = IdentityGroupUser = UserIdGroupColumn = 1 GroupPosition = Count (*) where UserId = UserId AND Column = 1 Int this way my table looks like this on a certain moment: 1 ; 1 ; 1 ; 02 ; 1 ; 1 ; 13 ; 1 ; 1 ; 24 ; 1 ; 1 ; 3
But then i would, for example, like to delete the 3rd row and i like to renumber the last column so form this:1 ; 1 ; 1 ; 02 ; 1 ; 1 ; 14 ; 1 ; 1 ; 3 <- this is my problem to this:1 ; 1 ; 1 ; 02 ; 1 ; 1 ; 14 ; 1 ; 1 ; 2 <- here it is solved
Whats the simplest sql stored procedure to perform this reordering task??? Thanks, Wes

So far I'm able to populate an ajax control toolkit reorder list with an SQL table, but I can't get it to reorder through the database.The SQL table is something like this-int ListID, varchar Title, int SortingOrder (SortingOrder always goes 1-n, there are no duplicates and no gaps) When the user changes the position of an entry, I need the reorder list to update the SortingOrder of all the pages between the starting and ending place of the reordered entry. I already have that function written, ReorderListEntries (int OldSortingOrder, int NewSortingOrder), but how and where do I call it?Basically, when the user reorders the list, I need it to-1. get the old and new positions of the reordered entry.2. pass this information back to the server3. call ReorderListEntries (old,new)4. partial page refresh the listHelp with this one will be greatly appreciated.
How or is there a way to reorder the packages in BIDS? Right now they are ordered by when they are created with the newest ones on the bottom. I'd like to organize these in more of a logical order but am unsure of how to do so.
Is there a way to reseed the Identity column in SQL Server Compact Edition? The following command does not appear to work DBCC CHECKIDENT (Table_Name, RESEED, 0) and I cannot seem to TRUNCATE the table either. Not sure if table truncation is even supported.
we are using a custom persistence framework on an SQL Server Compact Edition (3.5) database. It might occur, that a class gets persisted into a table having only a single IDENTITY column. Even worse, there may be additional columns in the database the persistence layer is not aware of. I'm now looking for a way to insert rows into that kind of table without specifying any column values. In SQL-Server 2005 (also Express edition), there is a form
INSERT INTO table DEFAULT VALUES;
which does the job. Unfortunately, this construct doesn't seem to be supported by the Compact Edition.
I know that it is possible to encrypt data fields in SQL Server 2005, but I can't find anything about data encryption in the Compact Edition. Is this possible?
I have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?
Bitmask fields! I am capturing row changes manually via a high frequency ETL task. It works effectively however i am capturing the movement of multiple fields. A simple example, for Order lines, i have a price, a discount and a date. I am capturing a 001, 010, 100 respectively for each change.
I would like my users to be able to select from a dimension which has the 3 members in it and they can select one, multiples, or all values (i.e. only want to see rows that have had the date and price changed).
Obviously if i only had 3 columns i would use bit's and be done with it, i have many different values (currently around 24 and growing).
Use the Northwind database Products table as an example.Purchasing dept gets a report showing when inventory items on hand qty arebelow the reorder level.easy enough:Select ProductID, ProductName, SupplierID, UnitsInStock, ReorderLevelfrom Productswhere (UnitsInStock < ReorderLevel)Results:ProductID ProductName SupplierID UnitsInStock ReorderLevel2 Chang 1 17253 Aniseed Syrup 1 1325It would be nice to know what other products are purchased from this samevendor in case other items are close to their reorder level.All products for Supplier ID 1Select ProductID, ProductName, SupplierID, UnitsInStock, ReorderLevelfrom Productswhere SupplierID = 1Results:ProductID ProductName SupplierID UnitsInStock ReorderLevel1 Chai 1 39102 Chang 1 17253 Aniseed Syrup 1 1325This shows there is 1 more product (Chai) that also comes from Supplier 1.Is there a way to show all items from a vendor when some of the items arebelow the reorder level without needing a separate query for each vendor?Thanks
Hi all,I am trying to perform a delete that I could achieve in Access butneed to do this in sql2000.I have two tables Warranty and Registrations. I would like to deleteall items in the warranty table where there is a match inregistrations on a common field.I access the query would be:DELETE warranty.*FROM warranty INNER JOIN registrations ON warranty.BBMQCE =registrations.vins;But cannot replicate this in SQL server?Any help would be much appreciated.ThanksSam
in Table A Column is PriKey No Name 1 1 Apple 2 2 Orange 3 3 Juicy in Table B column is Prikey ColumnA Price 1 1 10 2 3 2 3 2 5
TableA.Prikey have Depency with TableB.ColumnA
when I am trying to Delete data from Table A , I got error message becaue the depency how to delete data when there have depency?
I just know when table have trigger , we can disable trigger before delete Data, and enable trigger when data deleted does there have a way to disable depency and then enable ?
Basically it's converting certain row values to new column. Every PloicyNum will have 1001 to 1006 Fixed InsCode values as a group.
Rule-1: InsCode value 1001 should always mapped to 1005 InsCode value 1002 should always mapped to 1006 InsCode value 1003 should always mapped to 1004
Rule-2: For a policyNum, If any Inscode value is missed from the group values 1001 to 1006, still need to mapped with corresponding values as shown in Rule-1
In the above sample data..
for PolicyNum - 1ABC20 , group values 1003,1006 are missing for PolicyNum - 1ABC25 , group values 1002,1003,1004,1005,1006 are missing
Create Table sampleDate (PolicyNum varchar(10) not null, InsCode Varchar(4) not null) Insert into Sample Date(PolicyNum, InsCode) Values ('1ABC12','1001')
Insert into Sample Date(PolicyNum, InsCode) Values ('1ABC12','1002') Insert into Sample Date(PolicyNum, InsCode) Values ('1ABC12','1003')
Hello all, I was wondering if anyone knew of a way to dynamically delete all of the values for a group of columns. What I mean by this is that lets say a table (TableA) has five fields (Field1, Field2, Field3, Field4, and Field5) with 100 rows of data. I want to delete all of the data in Field1, Field2, and Field4. I do not want to delete any of the data in Field3 and Field5. I would then end up with a table with 5 fields and 100 row, but only 2 fields (Field3 and Field5) have data.
The catch is that I can't hardcode the field names of the fields I want to clear out (Field1, Field2, and Field4) into the SQL. This is because if any new fields are eventually added to the table I want them to be cleared out as well without modifying the SQL.
I can hardcode the field names of the fields that I want to keep values for (Field3 and Field5) in the SQL.
If anyone has any idea how to do this, I would greatly appreciate it.

I'm working on a social network where I store my friend GUIDs in a table with the following structure:user1_guid user2_guidI am trying to write a query to return a single list of all a users' friends in a single column. Depending on who initiates the friendship, a users' guid value can be in either of the two columns. Here is the crazy sql I have come up with to give what I want, but I'm sure there's a better way... Any ideas?SELECT DISTINCT UserIdFROM espace_ProfilePropertyWHERE (UserId IN (SELECT CAST(REPLACE(CAST(user1_guid AS VarChar(36)) + CAST(user2_guid AS VarChar(36)), @userGuid, '') AS uniqueidentifier) AS UserId FROM espace_UserConnection WHERE (user1_guid = @userGuid) OR (user2_guid = @userGuid))) AND (UserId IN (SELECT UserId FROM espace_ProfileProperty))
This is a report I'm trying to build in SQL Reporting Services. I can do it in a hacky way adding two data sets and showing two tables, but I'm sure there is a better way.
TheTable Order# Customer Status
STATUS has valid values of PROCESSED and INPROGRESS
The query I'm trying to build is Count of Processed and INProgress orders for a given Customer.
I can get them one at a time with something like this in two different datasets and showing two tables, but how do I achieve the same in one query?
Select Customer, Count (*) As Status1 FROM TheTable Where (Status = N'Shipped') Group By Customer
