Loop Through Table Until Max Amount?
Sep 10, 2012
I have a table with AmountSold and AmountLeftWith. I have to buy from the customers until the amount bought =250,000.
The max that user can buy is 250,000 so customers 1-3 get left with 0 (AmountLeftWith ) and customer 4 with 577 (AmountLeftWith ) after the update as user couldn't buy the entire amount as it would have exceeded 250,000. Preferably the query should stop afterwards and not proceed to check the other customers.
--===== If the test table already exists, drop it
IF OBJECT_ID('TempDB..#tmpCustomerAmount','U') IS NOT NULL
DROP TABLE #tmpCustomerAmount
CREATE TABLE #tmpCustomerAmount (
[id] [int] IDENTITY(1,1) NOT NULL,
[Code] ......

I'm creating a temporary table in a Sql 2005 stored procedure that contains the transaction amount entered in a period <= the period the user enters.
I can return that amount in my result set. But I also need to separate out by account the amounts just in the period = the period the user enters. There can be many entries or no entries in any period. I populate the temporary table this way:
SELECT
t.gl7accountsid,
a.accountnumber,
a.description,
a.category,
t.POSTDATE,
t.poststatus,
t.TRANSACTIONTYPE,
t.AMOUNT,
case
when t.transactiontype=2 then amount * (-1)
else amount
end as transamount,
t.ENCUMBRANCESTATUS,
t.gl7fiscalperiodsid
FROM
UrsinusCollege.dbo.gl7accounts a
join
ursinuscollege.dbo.gl7transactions t on
a.gl7accountsid=t.gl7accountsid
where
(t.gl7fiscalperiodsid >= 97
And
t.gl7fiscalperiodsid<=@FiscalPeriod_identifier)
And poststatus in (2,3)
and left(a.accountnumber,5) between '2-110' and '2-999'
And right(a.accountnumber,4) > 7149
And not(right(a.accountnumber,4)) in ('7171','7897')
order by a.accountnumber
Later I create a temporary table that contains budget information. I join these 2 temporary tables to produce my result set. But I don't know how to get the information for just one period. For example, if the user enters 99 as the FiscalPeriod_identifier, I need a separate field that contains only those amounts(if any) that were entered for each account in Period 99.
Can anyone help? It may be that I am not seeing the forest for the trees, but I can't figure it out.
Thanks very much.

I need to delete data from a particular table which has more than half a million records. The data needs to be deleted is more than 200,000 records from the table. What is the best way to delete the data from the table other than importing into a temporary table and performing the same operation?
Let me know if the strategy to be followed is okay.
1. Drop all the triggers
2. Drop all the indexes
3. Write a procedure with a loop setting ROWCOUNT to 1000 and delete the records. ( since if I try to delete all the rows it will give timeout error )
The above procedure will delete 1000 records for each batch inside the loop till it wipes out all the data for the specified condition.
4. Recreate Indexes and Triggers.
Please let me know if there are any other optimal solution.
Thanx,
Zombie

Hi all,
I have a 2 main tables in my system. One is main table has ticket information location and so on. And detail table which hold all actions on that record with multiple money fields (its around 5 fields). it goes trough some crazy calculations on the detail table and get 5 results for each ticket. And this calculation is done everytime the ticket is looked at.
There is around 10 detail records per 1 main record. and the main table is around 7 mil. records
Now i got 2 options. I can create a trigger that does the calculation and update the main table show the results from there. This is going to affect all updates deletes and inserts.
OR
I can leave as it is so only when they view the ticket it does the calculation. Dont ask me how often they view it i dont have a clue.( if there is any suggestion how to get the count i could try to do it. )
:confused:
Suggestions
(My attitude is going towards the trigger way but 100 percent sure)

I am wondering if it€™s possible to lock a SQL table for specific amount of time, say 5 min.
There is a particular 'Phone' table on the database that should never get locked. Yet, during the development stages we have noticed that the table gets locked at time. The issue since has been resolved to the best of our ability, but, there is still a vague chance that the table can get locked due to the multiple jobs that query the table, when we go live.
If such a situation occurs, we just want to be able flip the switch that will send the server to the mirror mode and the previously mirrored database to become the principal.
So, I just want to recreate a situation by voluntarily locking the table.
Any help in this regard will be appreciated.

I need to show the total amount of rows in a specific table?
The query is as follows:
As part of the planning process to expand the database that supports Northwind operations, the IT manager would like to know how many rows are currently in specific tables so that he can conduct capacity planning.
The results needed include two columns, TableName( containing all the tables in the database and Rows, which contain the total amount of all the rows per table).

In
one of our forth coming projects, with ASP.Net/C#/MSSQL Server, We have
to deal with a Business table having about 15 millions of records. We
want to know, that which methodologies should we adopt, both regarding
front end and back end perspective, so the site could give optimised
performance. Also in place of a Dedicated Server, the Hosting Company
provides MSDE (that come with .net). Will this create any problem with
this project, that have such a huge table? Should we go for some
advanced database technique, such as, Clustering, Spliting Tables, etc.
Followings are the fields that the business table contains:
ID, Category ID (which comes from a Category table, each business is
under a category), BusinessName, SignupDate, Address1, Address2, Phone
Number,

I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)

I was writing a query to get the age and the retirement year for all the employees.And thought of using while loop so that I don't have to write IF conditions or case statements for all the ages.
I'm using the AdventureWorks2012 database.And the actual table looks like this.
SELECT * FROM HumanResources.Employee
*NOTE:- These tables are not the complete tables.
BusinessEntityID         JobTitle                 BirthDate       MaritalStatus     Gender
      1                Chief Executive Officer           1963-03-02  S              M
      2         Vice President of Engineering         1965-09-01        S                     F
     3             Engineering Manager          1968-12-13        M              M
     4             Senior Tool Designer              1969-01-23           S             M
[Code] ...
And after I wrote the query to get the age and the retirement year of all the employees I got 70 tables for all the ages from 30 to 70. As the starting age is 30 and the last age is 70 in the table.So,I just want to know how I can settle all the tables into a single table as a sinle result and not as multiple results.
The query for age and retirement year....
DECLARE @Counter INT
DECLARE @Duration INT
DECLARE @Result DATE
SET @Counter=(SELECT MIN(DATEDIFF(YY,BirthDate,GETDATE()))FROM HumanResources.Employee)
SET @Duration=30
[Code] .....
And the result tables.
BusinessEntityID   JobTitle   BirthDate   AGE   MaritalStatus   Gender   Retirement Year69  Â
Production Technician - WC60Â Â Â 1985-05-07Â Â 30Â Â SÂ Â Â MÂ Â Â 2045-08-25 22:36:38.160115Â Â

And it goes like this for 70 times. So just want to know how I can merge those 70 tables into a single table.

I am trying to loop through a table which has table metadata and create a:
- 'STORED PROCEDURE'
- This will SELECT all the data in the table and add a hashed column at the end
- Each table has a unique ID
-
Instead of a cursor would there be a set-based approach to achieving this?
METADATA TABLE :
IDTableNameColumnNameHashByteCalculation
111dbo.TableAColA CAST(ISNULL(LEFT(CONVERT(VARCHARColA, 120), 10),'NA') AS varchar) + '|' +
111dbo.TableAColBCAST(ISNULL(LEFT(CONVERT(VARCHAR,ColB, 120), 10),'NA') AS varchar) + '|' +

222dbo.TableBColBBISNULL(ColBB,'NA') + '|' +

From the above data I want to generate:
SELECT

Update Product Set Product.Voorraad = Product.Voorraad - Tal where ProductId = ProductId
To do this must I make a create a tempory table, store the query result in the table loop through the table and update table product, or can I try to create a function without a temporary table.

Instead I would just like to do something like…
Declare i date
For i=2014/01/01 to 2014/12/01
Select [Member Number],
sum(case when [Receipt Date]=i then Amount else 0 end) as [Rec +i]
From [Receipts Table]
Group by [Member Number]
Insert into [Receipts + i]
Don’t know if this is at all possible?

Hi. It seems to be very simple, actually, but I don't know if it isfeasible in TSQL. I have a sproc which gathers in one place many callsto different other sprocs, all of them taking a 'StoreGroupe'parameter. I would like to add a case where if the call has NOStoreGroupe parameter, the sproc should LOOP thru all records in tableStoreGroupeTable, read the column StoreCode, and pass that value as aparam to the other sprocs, as in:CREATE PROCEDURE MySproc(@StoreGroupe nvarchar(6) = NULL)ASif (@StoreGroupe is not null)BeginExec _Sproc1 @StoreGroupeExec _Sproc2 @StoreGroupeExec _Sproc3 @StoreGroupeExec _Sproc4 @StoreGroupe...............EndElseBeginA 'Group Code' has NOT been specifiedI want to take all the StoreGroups in tableStoreGroupeTable, in turn.I would like to do SOMETHING LIKE THIS:Do While not [StoreGroupeTable].EOFRead [Code] from [StoreGroupeTable]Set @StoreGroupe = The value I just readExec _Sproc1 @StoreGroupeExec _Sproc2 @StoreGroupeExec _Sproc3 @StoreGroupeExec _Sproc4 @StoreGroupe...............LoopEndGOIs that feasible in a sproc, or do I have to do this in the client(ADO) ?Thanks a lot.Alex.

Hello,Does anyone know of a way to loop thru a SQL table using code in a storedprocedure?I need to go thru each record in a small table and build a string usingvalues from the fields associated with a part number, and I can't find anyway to process each record individually. The string needs to be initializedwith the data associated with the 1st record's part number, and I need tobuild the string until a new part number is incurred. Once a new part numberis found in the table, the string is written to a different table and resetfor this next part number in the table. Need to repeat until all records inthe table have been processed.I use ADO in access 2000 to work thru local recordsets, I just can't findanyway to do this in a stored SQL procedure.Thanks for any suggestions, Eric.

Hello,
Anyone have any suggestions on creating a query that will randomly select records from a table, but not use those records again. I have some code that does it, but it uses the same fields over again, and also throws in some blank records that I did not specify in the query. I am creating a test engine that has to randomly ask questions.

The table looks something like this.
