SQL Server 2012 :: Update Quantities Over Multiple Records?

Mar 25, 2015

I have two tables that can be created with sample data using the DDL at the bottom of this post. What I'm looking to do is update the QtyReceived column in tblPurchaseOrderLineDetail from the Qty column in tblReceivedItems. However, the tricky part that I can't figure out is splitting these quantities out over multiple lines. I should only be allowed to receive up to the QtyOrdered column in tblPurchaseOrderLineDetail.

For a specific example from the sample data we'll look at PurchaseOrderDetailID 28526. From the tblReceivedItems, there are three records with quantities of 48, 48, and 20. From the tblPurchaseOrderLineDetail there are three records of QtyOrdered of 55, 45, and 20. What I would like to happen is fulfill the records in the tblPurchaseOrderLineDetail sequentially (essentially in order of ExpectedDate). So, the QtyReceived would be 55, 45, and 16 for the corresponding records. If there is already a quantity in the QtyReceived column, but it's less than the QtyOrdered column, the quantity needs to be added to the column (not overwritten).

DDL To CREATE Sample Tables and Data:

CREATE TABLE [dbo].[tblReceivedItems](
[ID] [int] IDENTITY(1,1) NOT NULL,
[PurchaseOrderDetailID] [int] NULL,
[Qty] [int] NULL)
SET IDENTITY_INSERT [dbo].[tblReceivedItems] ON
INSERT [dbo].[tblReceivedItems] ([ID], [PurchaseOrderDetailID], [Qty]) VALUES (1, 28191, 48)

SQL Server 2012 :: How To Quickly Update / Insert 3M Records In Large Table

Mar 28, 2015

Our system runs a SQL Server 2012 DB, it has a table (table_a) which has over 10M records. Our system have to receive data file from previous system daily which contains approximate 3M updated or new records for table_a. My job is to update table_a with the new data.

The initial solution is:

1 Create a table (table_b) which structur is as the same as table_a

2 Use BCP to import updated records into table_b

3 Remove outdated data in table_a:
delete from table_a inner join table_b on table_a.key_fileds = table_b.key_fields

4 Append updated or new data into table_a:
insert into table_a select * from table_b

As the test result, this solution is very inefficient. Step 3 costs several hours, e.g. How can I improve it?

SQL Server 2012 :: How To Perform Update Query That Involves Multiple Tables

Aug 31, 2015

I am trying to run an update statement against a vendor's database that houses HR information. If I run a regular select statement against the database with the following query, it returns without error:

SELECT "QUDDAT_DATA"."QUDDAT-INT", "NAME"."INTERNET-ADDRESS", "QUDDAT_DATA"."QUDFLD-FIELD-ID", "QUDDAT_DATA"."QUDTBL-TABLE-ID"

I am assuming I am receiving this error because it doesn't know where to find QUDDAT-INT? How can I fix that?

The "QUDDAT-INT" column houses the employee number. So in the case of the SELECT query above, I am testing against a specific employee number.

SQL Server 2012 :: Update Table Based On Existing Values In Multiple Rows?

Oct 1, 2015

The objective is to identify orders where an order fee has been applied incorrectly. I have multiple orders per customer, my table contains an orderID and a customerID. Currently if the customer places additional orders before the previous orders have been closed/cancelled, then additional fees are being applied.

Let's say I'm comparing order #1 to order #2. I need to identify these rows where the following is true:-

The CustID is the same.

Order #2 has a more recent order date.

Order #2 has a FeeDate Before the CancelledDate of Order #1 (or Order #1 has no cancellation date).

So in the table the orderID:2835692 of CustID: 24643 has a valid order fee. But all the subsequently placed orders have fees which were applied before the first order was cancelled and so I want to update the FeeInvalid column with a 'Y'. The first fee will always be valid.

I think I understand why the code I am trying doesn't achieve the result I want but I can't figure out how to write it correctly. Below is one example of code I've tried and also code to create the table and insert some test data.

update t1
SET FeeInvalid = 'Y'
FROM MockData t1 Join MockData t2 on t1.CustID = t2.CustID
WHERE t1.CustID = t2.CustID
AND t2.OrderDate > t1.OrderDate
AND t2.FeeDate > t1.CancelledDate
CREATE TABLE [dbo].[MockData](
[OrderID] [float] NULL,

Update Multiple Records From A Single ASP.NET Webpage

Mar 3, 2004

Got a beginner question here...
Let's say I have a database table that houses server information with four columns: make, model, serial #, ip address. And assume there are ten rows with that information filled out. How could I display all the rows of information on a single webpage (ASP.NET), with all the fields being editable; and a single save button that would send any changes to the database (in reality I guess it would be sending all rows and fields to the database, and just overwrite the previous data).

Could a page such as that be created using FrontPage 2003 or Dreamweaver MX 2004?

This would be strictly for updating information. I would have a separate form for adding a new entry.

Thanks for your help.

Update Records Matching Multiple Criteria

I have an 'update' query that looks like this:

update wce_contact
set blank = 'missing'
where website in ('www.name1.co.uk','www.name2.co.uk','www.name3.co.uk')

I know this query will set 'blank' to missing when it matches the above websites. However if i wanted to set blank to 'missing' where mail1date is not null and mail2date is not null (keep going to mail18date not null) how exactly would i go about this?

I guess it would be a case of adding another bracket somewhere but im unsure?

Transact SQL :: How To Update Multiple Records In A Table

Jul 23, 2015

I need to update more than one record at once. I have ~ 100 records that I have to update and don't want to execute query 100 times.

My query looks like this:

Update Table1
Set Table1.field1 = ( select Table2.field1 from Table2 where Table2.field2 IN ('a', 'b', 'c')
where Table1.field2 IN ( 'a', 'b', 'c')

It obviously failed because subquery returned more than one value and error message stated that I can't use '=' operator in this case.

My question: how could I update the same column from many records in one execution?

Update Multiple Varbinary Records With Single Sql Statement

Jan 16, 2007

I am renovating an existing application and am converting the existing passwords into hashed values using SHA1. I know how to compute the hashed values as a byte array for each record. What I don't know how to do easily is update all of the records i a single call to the database. Normally, I would just do the following:UPDATE HashedPassword = someValue WHERE UserID = 101;
UPDATE HashedPassword = someOtherValue WHERE UserID = 102;
...

What I don't know is what someValue and someOtherValue should be. How do I convert my byte array into string representation that SQL will accept? I usually execute multiple statements using Dim oCmd as New SqlCommand(sSQL, MyConn) and then call oCmd.ExecuteNonQuery().
Alternatively, I found the following code that uses the byte array directly but only shows a single statement. How could I use it to execute multiple statements as shown above?'FROM http://aspnet.4guysfromrolla.com/articles/103002-1.2.aspx

'2. Create a command object for the query
Dim strSQL as String = _
"INSERT INTO UserAccount(Username,Password) " & _
"VALUES(@Username, @Password)"
Dim objCmd as New SqlCommand(strSQL, objConn)

'3. Create parameters

SQL Server 2012 :: Concatenate Multiple Rows In Multiple Columns

Best Way To Gather Large Quantities Of Data

Mar 30, 2008

Hi all,

I have a table which basically stores multiple users' responses to a questionnaire. I want to calculate certain statistics on this data (for example: how many users selected a specific answer to a question). If there are many questions and possible answers, then this can get really inefficient. I was wondering what would be the best way to go about doing this.

Currently, I was thinking of using what I believe are called crosstabs:


Code:

SELECT (SELECT COUNT(*) FROM tableName WHERE Q1answer='value1'), (SELECT COUNT(*) FROM tableName WHERE Q1answer='value2'), (SELECT COUNT(*) FROM tableName WHERE Q2answer='value1'), etc...



Is this the best way to go about this or is this really inefficient?

Transact SQL :: Sum Quantities For Given Transaction Type

Nov 4, 2015

My data is in 4 columns and multiple rows, like this

PartNo  Quantity TransactionType         TransactionDate
aaa       25         Incoming                    2015-03-01
aaa       25         Incoming                    2015-03-01
aaa       50         Transfer                     2015-03-02
bbb       30         Incoming                   2015-03-03
bbb       30         Transfer                     2015-03-03
ccc        50         Incoming                   2015-05-15
ccc        75         Incoming                   2015-05-20
ccc        50         Transfer                    2015-05-18
ccc        75         Transfer                    2015-05-21

What I need to achieve is sum the quantities for a given transaction type, group it by Part Number and add an additional column where the Transaction Date for Transfer Type rows would become the Transfer Date. Each part would have one row. The resulting data would look like this.

PartNo   Quantity   IncomingDate   TransferDate
aaa        50           2015-03-01      2015-03-02
bbb        30           2015-03-03      2015-03-03
ccc         125         2015-05-15      2015-05-21

SQL Server 2008 :: Multiple Records On One Row

Aug 20, 2015

I have a table of customer sales (dbo].[CustomerSales] which has a complete record od sales of our products for the past 5 years. I would like to create a report that extracts all the sales per customer on one row ie [CustomerID] 00011 has had 25 sales in the past 5 years and I would like to have their sales from left to right (starting with their earliest sale date at the beginning [SaleDate] field on the one row. I would also like to include the store location field [Location] along with the date the sale took place. So in other words the extract would look something like:

[CustomerID], [SaleDate], [Location], [SaleDate], [Location], [SaleDate], [Location], [SaleDate], [Location], [SaleDate], [Location], etc etc

Obviously some customers will have had less sales than others in which case I’m assuming these fields would just contain NULL values.

SQL Server 2008 :: Loop Through Date Time Records To Find A Match From Multiple Other Date Time Records?

Aug 5, 2015

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.

E.g.

Query 1

Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'

Table

Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'

Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.

I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

SQL Server 2012 :: 2 Records At A Time?

Nov 15, 2013

I am developing a form for a mortgage company. There can be any number of borrowers on a given loan, and the business has asked that this form return only 2 borrowers at a time for a loan. For example, if there are 3 borrowers for a loan, they want the first copy of the form to print the first 2 borrowers and then another copy of the form to print the 3rd. No matter how many copies are printed, they want the borrower information to be labeled as 'Borrower1' xyz and 'Borrower2' xyz. Also, there will be a LOT more fields returned on the real form, so the sample information below is very simplified test data.

Sample Data:
CREATE TABLE #t (LoanID VARCHAR(5), BorrowerName VARCHAR(20), BorrowerOrder INT);
GO
INSERT INTO #t VALUES
('::E', 'John Smith', 0)
, ('::E', 'Jane Smith', 1)
, ('::E', 'Rob Jackson', 2)
, ('AF_CF', 'Sloan Burton', 1)

[code]...

I don't want that 2nd record to return. This result is what makes me think of gaps and islands, but I don't know if the 2nd record is really an island since it's (1) not stored this way...it's returning this way because of the query and (2) it's not sequential data..I tried restricting this by putting this into a CTE and then returning only the odd numbered records like I have below. This runs pretty quickly when dealing with one loan. But...I am concerned that the CTE will be slow when we run batches of loans.

Attempt with CTE:
--With CTE
;WITH cte AS
(SELECT
Borrower1 = BorrowerName
, Borrower2 = LEAD(BorrowerName) OVER(ORDER BY BorrowerOrder)
, RowNumber = ROW_NUMBER() OVER(ORDER BY BorrowerOrder)

[code]...

Is there a better, cleaner way to do this? Or is the CTE the best way to go?

Deleting Records From Multiple Tables In SQL Server

Jul 13, 2007

I'm new to relational database concepts and designs, but what i've learned so far has been helpful. I now know how to select certain records from multiple tables using joins, etc. Now I need info on how to do complete deletes. I've tried reading articles on cascading deletes, but the people writing them are so verbose that they are confusing to understand for a beginner. I hope someone could help me with this problem.



I have sql server 2005. I use visual studio 2005. In the database I've created the following tables(with their column names):



Table 1: Classes --Columns: ClassID, ClassName

Table 2: Roster--Columns: ClassID, StudentID, Student Name

Table 3: Assignments--Columns: ClassID, AssignmentID, AssignmentName

Table 4: Scores--StudentID, AssignmentID, Score



What I can't seem to figure out is how can I delete a class (ClassID) from Classes and as a result of this one deletion, delete all students in the Roster table associated with that class, delete all assignments associated with that class, delete all scores associated with all assignments associated with that class in one DELETE sql statement.



What I tried to do in sql server management studio is set the ClassID in Classes as a primary key, then set foreign keys to the other three tables. However, also set AssignmentID in Table 4 as a foreign key to Table 3.



The stored procedure I created was



DELETE FROM Classes WHERE ClassID=@classid



I thought, since I established ClassID as a primary key in Classes, that by deleting it, it would also delete all other rows in the foreign tables that have the same value in their ClassID columns. But I get errors when I run the query. The error said:



The DELETE statement conflicted with the REFERENCE constraint "FK_Roster_Classes1". The conflict occurred in database "database", table "dbo.Roster", column 'ClassID'.
The statement has been terminated.



What are reference constraints? What are they talking about? Plus is the query correct? If not, how would I go about solving my problem. Would I have to do joins while deleting?

I thought I was doing a cascade delete. The articles I read kept insisting that cascade deletes are deletes where if you delete a record from a parent table, then the rows in the child table will also be deleted, but I get the error.



Did I approach this right? If not, please show me how, and please, please explain it like I'm a four year old.



Further, is there something else I need to do besides assigning primary keys and foreign keys?
