how do I write one query that will accomplish this?
We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process

I know it sounds very simple with the subject line but for me it's not.
BACK GROUND
My Client is using Crystal Reports 8.5 and SQL Server.
a View is bound to this report and they use Select Expert of CR 8.5 IDE to generate Reports manually.
now there are 3 tables in Question
Billing_Revenue, Billing_Revenue_History and Billing_Revenue_Revision
and the Fields in Question are Interstate_Revenue and International_Revenue.
Every end of the Quarter the Billing_Revenue data is moved to Billing_Revenue_History.
Billing_Revenue_Revision has the revised data if the "Filer" has submited the changed/Revised Data again to the Company.
Bill Run = is the Process they call when they generate the Reports for a perticular Billing Period.
they do it every month. But sometimes they need to generate Invoices for the OLD Periods.
if we put the problem in simple words,
they want to get the Revenue Columns from Billing_Revenu if they run the "Bill Run" in the Current Quarter (Billing Cycle),
else if the Billing Cycle is older than current Quarter (cycle), then they want to first check in the Revision Table and if that Filer has submitted the revised data in that Cycle then get it from there
else
look into History Table and if the filer is found there for that cycle than get the data from there
here's the requirement given to me by my system Analyst.
User enters list of filer ID=USER_FILER_ID and cycle ID=USER_CYCLE_ID
Get CURRENT_CYCLE= Max CYCLE_ID from Billing_Cycle
Get USER_PERIOD_ID = Period ID from Billing_Cycle using USER_CYCLE_ID
Get PERIOD_FIRST_CYCLE= Min Cycle ID for USER_PERIOD_ID from Billing_Cycle
For each USER_FILER_ID
If USER_CYCLE_ID=CURRENT_CYCLE
Pull revenue from BILLING_REVENUE /*Process stops here*/
ELSE
{
If USER_PERIOD_ID exists in BILLING_REVENUE_REVISIONS BRR for USER_FILER_ID
Get the max (cycle_id) from BRR to pull revenue columns with most recent filing of USER_PERIOD_ID from BRR /*one filer may have more than one revision for the same period id*/
ELSE
IF PERIOD_FIRST_CYCLE exists in BILLING_REVENUE_HISTORY for USER_FILER_ID
Pull revenue information
}

Hi all,

Art Count
------------
12A 3

Hi,
I have a trigger that fires on update, populating a varchar field [ExampleDate_Str] with the dd/mm/yy format of the inserted datetime field [ExampleDate]. It works, but I don't want to rewrite it for the thousands of datetime fields in hundreds of tables in my db. So I am looking for a way to do something like this in a trigger -
for each column in triggered tableset @ColName = (the column name)if datatype(@ColName) = datetimeset @ColName + "_Str" = convert(varchar(8),ExampleDate,3)next
Obviously the above doesn't work in SQL or indeed any other language yet invented - is it possible to make it so that it does, and if so, how? The main points are to read the column name into a variable, check the datatype, and modify the column named @ColName + "_Str".
Thanks...
I´m wondering how to solve the following scenario with SSIS
I have a CITY table and a STATE table, I have to load a file with the information regarding to the CITY:
the state table is like this:
StateCode(PK) stateLegalCode stateName
============= ============== =========
1 01 Florida
the city table is like this:
citycode(PK) cityLegalCode cityname StateCode(FK)
============ ============= ======== =============
1 1001 Quakertown 1
the file has the following information
cityLegalCode cityName
============= ========
01-1001 Quakertown
...
how can I load the file into CITY table:
1-) with the file's cityLegalCode I have to split the string and if the two initial digits are 01 the registry must have 1 in the StateCode(FK).
how can I do something like that using SSIS???
thanks

I am loading files with same format from two different locations in to one database. First, my SSIS connects to location 1.
Lets Say
Location1 : C:LoadFilesImport
Location2 : D:LoadFilesImport
Location one has three different set files starting with
First Set: AP_1, AP_2,AP_3,
Second Set: VD_1, VD_2, VD_3,
Third Set: BK_1,BK_2,BK_3,
This SSIS set to run every 3 hours, if it finds files of any set load them. While loading it has to insert into a derivedcolumn called CustID. If the file name Starts with AP_ , custiD values should be as 101
AP_1 goes to Table1
AP_2 goes to Table2
AP_3 goes to Table3
If the file name Starts with VD_ , custiD values should be as 201
If the file name Starts with BK_ , custiD values should be as 301
after processing all these files in first location, the SSIS looks for files in second location and does the same?
--How to achieve CustID depending upon file name ?

Hey all - got a problem that seems like it would be simple (and probably is : )
I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me.
Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs:
'**********************************************************************
' Visual Basic Transformation Script
'************************************************************************
' Copy each source column to the destination column
Function Main()
DTSDestination("CM") = Month(Now)
DTSDestination("CY") = Year(Now)
DTSDestination("Comments") = DTSSource("Col031")
DTSDestination("Manufacturer") = DTSSource("Col030")
DTSDestination("Model") = DTSSource("Col029")
DTSDestination("Last Check-in Date") = DTSSource("Col028")
Main = DTSTransformStat_OK
End Function
***********************************************************
Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data.
thanks in advance!

Hi,
I'm not sure if this can even be done but I will ask anyway.
I have a table that has a sales price field in it. I have another field in that table called commission. The commission is 15% of the sale price. Is there any SQL that will calculate and automatically put that value in it, or only allow you to put the correct value in?
Hope this makes sense and hope someone can help.
Thanks for your time.

(Using MS SQL by the way)
Hello,
I'm struggling with a query that needs to use Not Exists between two unrelated tables. I'm not sure of the best way to handle this with SQL Query Analyzer.
I have three tables, employees, courses and training_records. There is no link between employees and courses other than through the training records table. My problem is that I am unsure of how to pull all employees and an associated course id and course title when there is not a training record for that employee/course?
I had a query that would work when I specified the course id, but I wanted to do this for a list of about 25 courses.
SELECT e.empnumber, e.Nickname + ' ' + e.lastname as employeeName
FROM empdata e
WHERE NOT EXISTS (SELECT * FROM #TrainingRecords tr
LEFT JOIN #TrainingCourses tc
ON tc.ClassID = tr.classid
WHERE tc.ClassID = 1377
AND tr.employee = e.empnumber)
I then modified it to get the classid and name
SELECT e.empnumber, e.Nickname + ' ' + e.lastname as employeeName, tc.ClassID, tc.ClassName
FROM empdata e
LEFT JOIN #TrainingCourses tc
ON tc.ClassID = 1377
WHERE NOT EXISTS (SELECT * FROM #TrainingRecords tr
WHERE tr.ClassID = tc.ClassID
AND tr.employee = e.empnumber)
I then got it to work using the full list
SELECT e.empnumber, e.Nickname + ' ' + e.lastname as employeeName, tc.ClassID, tc.ClassName
FROM empdata e
LEFT JOIN #TrainingCourses tc
ON tc.ClassID in (1032, 1054, 1059, 1060, 1062, 1063, 1069, 1072, 1074, 1075, 1122, 1189, 1190, 1191, 1192, 1193, 1210, 1218, 1219, 1220, 1310, 1377, 1411)
WHERE NOT EXISTS (SELECT * FROM #TrainingRecords tr
WHERE tr.ClassID = tc.ClassID
AND tr.employee = e.empnumber)
My results seem to work like I want them to, but I have never joined a table without actually joining on a value from each table. In this case I join to a list of values and that just looks odd to me. Is this good or crappy development? Is there a better way this should be done?
Hi all,
I have the following SQL script that works fine, but I like to view all the fields for the records that are not exists in “capdb.dbo.abc “ for “capdb2.dbo.abc� table instead of some fields :
select distinct cp2abc.subj_num , cp2abc.abc_age, cp2abc.ABC_LETHARGY, cp2abc.ABC_STEREOTYPY
, cp2abc.ABC_STEREOTYPY, cp2abc.ABC_HYPERACTIVITY, cp2abc.ABC_INAPPROPRIATE_SPEECH
from capdb2.dbo.abc as cp2abc, capdb.dbo.abc as cp1abc
where not exists
(select cp1abc.subj_num, cp1abc.abc_date from capdb.dbo.abc as cp1abc where cp2abc.subj_num = cp1abc.subj_num
and cp2abc.abc_DATE = cp1abc.abc_date)
I tried cp2abc.*, but the returns entire the records in the tables.
select cp2abc.*
from capdb2.dbo.abc as cp2abc, capdb.dbo.abc as cp1abc
where not exists
(select cp1abc.subj_num from capdb.dbo.abc as cp1abc where cp2abc.subj_num = cp1abc.subj_num
and cp2abc.abc_DATE = cp1abc.abc_date)
Is there a way to accomplish this

Hello,
I have two tables with the same field layout, and they both have the same field as the Primary Key. They just contain different data. I would like to know if a record exists in one, or both, tables.
The tables are InvTemp1 and SalesTemp1. The key for both is stock_number.
Here is the command so far:
SELECT COUNT(*)
FROM InvTemp1 INNER JOIN SalesTemp1 ON InvTemp1.Stock_number = SalesTemp1.Stock_number
WHERE (InvTemp1.Stock_number = '101053')
Thank you for any ideas,

for a table :
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[myTable]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[myTable]
GO
but I dont find it for a column
Thank you
Hi
I am trying to insert values into a table that doesn't exist there yet from another table, my problem is that because it is joined to the other table it keeps on selecting more values that i don't want.
Code Snippet
SET NOCOUNT ON
INSERT INTO _MemberProfileLookupValues (MemberID, OptionID, ValueID)
SELECT M.MemberID, '6', CASE M.MaritalStatusID WHEN 1 THEN '7'
WHEN 2 THEN '8'
WHEN 3 THEN '9'
WHEN 4 THEN '10'
END
FROM Members M
INNER JOIN _MemberProfileLookupValues ML
ON M.MemberID = ML.MemberID
WHERE M.Active = 1
AND OptionID <> 6
When i execute that code it returns all the values, let say OptionID = 3 is smoking already exists in the MemberProfileLookupValues table then it is going to select that persons memberID
I want to insert only members values that aren't already in the _MemberProfileLookupValues from the Members table (I think that it is because of the join statement that is in my code, but i don't know how i am going to select members that aren't in the table, because i have a few other queries that are very similar that are inserting different values, so ultimately
ONLY INSERT THE MemberID the values 6 and the statusID of X if it is not in the table already.
Any ideas / help will be greatly appreciated. Please help.
Kind Regards

I have been asked to create PK on many tables using a query on all tables where we do not have clustered indexes. Some of the tables contains PK but non-clustered. If in a table there are no PK, then how to decide on which column PK can be created? can we do it with the query without data loss and without human intervention?

I am setting my error tables.What i want to do is.If i find any data within my error tables i want an email to be sent to me.
How can i achieve this??
Please let me know
Well, actually, as in the title. I have a table. The script should add a column if that column doesn't exist already. I use VB to combine the two queries. So what I want:
Query1: Does the column exists:
if No,
query2: create the column
How can I achieve this?

How to check to make sure a column does not exist before adding it? Be nice to do this in t-sql code instead of using ado.net. It seems as if the IF NOT EXISTS is not supported in SqlCe 3.1? I am trying to do this but I get the token error:
IF NOT EXISTS (
select *
from Information_SCHEMA.columns
where Table_name='authors' and column_name='NewColumn'
)
select 'no'
Is there a list of all CE supported t-sql commands?
Thanks,

I like writing concise and compact sql code without cursors if possible. My current dilemma has me stuck though.I have 3 tables, but one of them is optionally used and contains a key element of TimeOut to determine which Anesthesia CrnaID to use. It is the optionally used part that has me stumped.
Surgery table
CaseID
Patient
(Sample data: 101,SallyDoe 102,JohnDoe)
Anesthesia table
CaseID
CrnaID
(Sample data:
101,Melvin
102,Bart
102,Jack)
AnesthesiaTime table (this table is optionally used, only if the crna's take a break on long cases)
CaseID
CrnaID
TimeIn
TimeOut
(Sample data:
102,Jack,0800,1030
102,Bart,1030,1130

Select Patient INNER JOIN Anesthesia produced too many case results. So, I figured out there is an AnesthesiaTime table that only gets used if the anesthesia guys take time-outs. That doesn't happen all the time. I could use TOP 1 on the Anesthesia table, but technically I need to read the AnesthesiaTime table and locate the last time and pull that crna, Jack. I'm not sure how to deal with an optional table. I believe the IF Exists will be pertinent, but not sure of how to build this query. I've tried subquery without success.
i need to check that the column exist in the table if yes the update/insert value in the column else i need to add the new column like new browser name in the table.

IF OBJECT_ID(''tempdb..#tempTable.Column'') IS NOT NULL
But its returning me a null every time. Is there any other way to check if column exists in temporary table.
