Transact SQL :: Insert Records From Multiple Tables
Aug 30, 2015
This is a bit lengthy, but lets say we have three tables
a) tblSaleStatementCustomer
b) tblCreditors
c) tblReceiptDue
which shows records like below
Table 1 - tblSaleStatementCustomer
ID CustomerName VoucherType Outbound Inbound CustomerType
----------------------------------------------------------------------------------------------
1 ABC Sales 10000 0 Dealer
2 MNC Sales 9000 0 Dealer
3 MNC Sales 4000 0 Dealer
Table 2 - tblCreditors
ID Name OpeningBalance
----------------------------------------------------------------------------------------------
1 ABC 20000
2 MNC 15000
3 XBM 18000
4 XYZ 12000

Lets say we are executing this query below to retrieve each customer and the amount associated to a table
"INSERT INTO tblReceiptDue (Dealer, Amount) SELECT CustomerName, SUM(CASE WHEN VoucherType = 'Sales' then Outbound ELSE - Inbound END) AS AMOUNT from
tblSaleStatementCustomer WHERE CustomerType = 'Dealer' GROUP BY CustomerName"
Which display the data like below
DEALER AMOUNT
------------------------------------------------
ABC 2000
XYZ 1000
However I have one more table TABLE2 which contains two columns
DEALER OPENING
-------------------------------------------------------
ABC 5000
XYZ 7000
I want to modify my query in such a way that AMOUNT column should also add
OPENING from TABLE2 So that I must get the result like below
DEALER AMOUNT
------------------------------------------------
ABC 7000
XYZ 8000

I need to update two tables. I have created a view and am using the code in the attached file to insert into the two tables.
The page loads without errors, but I get this message that the view is not updatable because the modification affects multiple base tables.
I thought this was the purpose of views?
Does anyone have any suggestions? I am using Dreamweaver MX and SQL Server.
Thanks!

Hi,
Currently, I'm using the following steps to migrate millions of records from Foxpro tables to SQL Server tables:
1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables in a dummy database. All the SQL tables have the same columns as the Foxpro tables.
2. Manipulate the data in the SQL tables of the dummy database and save the manipulated data into the SQL tables of the real database where the tables may have different structure from the corresponding Foxpro tables.
I only know the following ways to import Foxpro data into SQL Server:
#1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables
#2. Transfer Foxpro records to .dat files and then Bulk Insert to SQL Server tables
#3. DTS Foxpro records directly to SQL Server tables
I'm thinking whether the following choices will be better than the current way:
1st choice: Change step 1 to use #2 instead of #1
2nd choice: Change step 1 to use #3 instead of #1
3rd choice: Use #3 plus manipulating in DTS to replace step 1 and step 2
Thank you for any suggestion.

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?

I need to compare records between two tables. There is no ID in the tables to do a simple join between them. So, what I'm looking for is: get the first record from table1 and read all record from table2 and give me back the most similar record. The String Distance is a predefined function.
Select a.table1
,b.table2
from table1 a, table2 b
where StringDistance (''a.table1,'b.table2') >90

I need to be able to bulk insert a bunch of tables from their corresponding flat file. I have created an XML file (see below) which has the file name/table name pair at each node. I then created a ForEachLoop task and used the Node enumeration type and the following OuterXpathString: ReferenceFiles/File. At this point I get lost. How do I pass the 2 inside node values (file name and table name) to variables which I can then use as expressions for the bulk insert task inside the Foreach?
Here is XML file:
Code Snippet
<ReferenceFiles>
<File>
<FileName>Ref_Categories.txt</FileName>
<TableName>Ref_Categories</TableName>
</File>
<File>
<FileName>Ref_Configs.txt</FileName>
<TableName>Ref_Configs</TableName>
</File>
</ReferenceFiles>

The query repeats the Header row value for all children associated with the header.I need the output of the query in XML format such that..For every Header element in the XML, all its children should come under that header element//I am using -
SELECT
Cols
FROM
Table Names
FOR XML PATH ('Header'), root('root') , ELEMENTS XSINIL
This still repeats the header for each detail (in the XML) , but I need all children for a header under it.I basically want my output in this format -
<Header >
<detail 1>
</detail 1>
<Detail 2>
</Detail 2>
<detail 3>

I'm trying to insert records into "holding" table and write back identity column value (Entry_Key) to the original table. So my setup is I have two tables; tblEWPBulk and tbleFormsUploadEWP. Users will enter records into tblEWPBulk and use BatchID to group records, once batch entry has been completed (usually less than 30 records) user will click on UploadAll button and insert records (not all fields) into tbleFormsUploadEWP. One record in tblEWPBulk can be sent multiple times to the holding table but tblEWPBulk will need to have latest Entry_Key captured. Records are sent from holding table to DB2 z/VSE using SQL stored procedure and based on certain logic records are marked uploaded or certain error capture... that part works fine.
So for example I want to send
BatchID, AccountNumber, Period, ReceiveDate, AccountType, ReturnType, NetProfitOrLoss, TaxCredit FROM tblEWPBulk to the holding table and write back Entry_Key (identity column) back to the record in tblEWPBulk (field called UploadEntryKey). As I said one record could be sent to the holding table multiple times until uploaded or deleted and UploadEntryKey always needs to be updated so that when results are processed response from the DB2 can be inserted into table and presented to the user.
No foreign key relationship exists since records in the holding table get sent to the archive table and table is truncated and entry_key starting value reset back to 2000... just some DB2 restrictions.

DECLARE @Today date
declare @TBLSalesCounts as table( StatusDesc varchar(100), Value money)

I end up with the following result :
How would I alter my while loop to only insert the sum total of each day, instead of creating duplicates for each day.
E.g.
2015-04-22
1150.00
2015-04-21
785.00
2015-04-20
750.00

I have a problem where I have 2 compare 2 records from the same table. This part looks easy but the problem is for a User there can be multiple records and I have 2 compare each record with its previous instance based on the timestamp. Not only I have to compare I have to perform some analysis. Below is the Table script and sample output.
Givens: All SQL Server 2008 or 2012 tools at your disposal.
Production database contains the following tables (simplified for example: constraints ignored, etc.) associated with a racing video game’s server.
-- A player of our game
-- Table greater than 10 million rows
CREATE
TABLE [dbo].[User]
(
[UserId]
[bigint] NOT
NULL
,[country]
[int] NULL
-- User’s home country
,[name]
[nvarchar](15)
NULL -- User’s displayable name (‘John’, ‘Bill’)
,[subscriptionTier]
[int] NULL
)
-- 0 == free, 1 == paid, for instance
Assume that rows get written into the event tables at a rate of 1,000 a minute,are never updated once written and currently are only read on a replica/reporting server.
Question Background: Write up a single query that would return the following: List of users and whose “TotalMoneyEarned” value ever grew (between logon events) at a rate of more than 1,000 per minute (we’d consider these suspicious and flag them for later investigation).
For instance, if the sample data were:
-- example of [Events.UserLogon] data -- not the query output we want
EventId UserId TotalMoneyEarned LogonDate
----------- -------------------- ---------------- -----------------------
1 1 1000 2010-10-16 00:19:56.460
2 1 1500 2010-10-16 00:20:56.460
3 1 3000 2010-10-16 00:21:56.460
4 1 10000 2010-10-16 00:29:56.460
Event 1 is okay because there’s nothing to compare it against
Event 2 is okay because the TotalMoneyEarned only grew 500 in a minute
Event 3 should be flagged, as the value grew 1500 in a minute
Event 4 is okay, as it grew 7,000 in 8 minutes (< 1000 per minute)
Query Output (your query should return data in a format like this):
User Flagged Logon Time Rate Since Last Logon (money/minute)
John 2010-10-16 00:21:56 1500
Dave 2010-10-16 00:30:50 3200
Bill 2010-10-16 00:35:23 1000
It is likely that you will need to create sample data for both the User and [Events.Logon] tables. We are looking for a single query that returns data like what is represented in Query Output.

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?
