Use A Column In 2 Ways
Aug 9, 2013
I have to made a change and want to see it this is possible. The column IDPRT# is used here as MAX. THe user wants to exclude a few of the items which skews the average. Can i also select the IDPRT# a second time? and then in the CRystal reports I can select not =? but will this mess up the MAX line in any way?
SELECT "OEIND94"."IDDOCD" AS INV_DATE,
"OEIND94"."IDORD#" AS ORD_NUM,
"OEIND94"."IDORDT" AS ORD_TYPE,
"OEIND94"."IDPRLC" AS PROD_FAMILY,
"OEIND94"."IDPR$C" AS PRICE_CODE,
"OEIND94"."IDCOM#",
MAX("OEIND94"."IDPRT#") AS ITEM_REF,
"ICPRT1"."IARCC4" AS PROD_TYPE,
[code]....

Hi All,
My week starts on Monday rather than on Sunday which is default(US, English) in SQL Server and would like to change the same so I would get proper weeknumber and dayindex using DATEPART.
I am looking at different ways of setting DATEFIRST(SET DATEFIRST 1) in SQL Server 2005.
I could set in a stored procedure, but this isn't a feasible way for me because I am using .nettiers to generate by business objects and stored procedures. I need to alter the sp's everytime I newly generate the code and sp's.
I couldn't set it in a function which I was hoping initially. I understand this datefirst is stored in one of the sys table in MASTER DB and I couldn't find a straight forward way to change this.
Can anyone suggest me a way to set the DATEFIRST either at a database level or at a server level(probably by changing the sys table in MASTER DB).
Any help on this would be greatly appreciated.

I have I rather complex query and need to display a Sum in different ways. Now I'm wondering if the performance improves if you nest the queries in the described way. To me it looks, as if the sum just has to be calculated once?
select SUM(tiempo) as time_minutes,
CONVERT(varchar(5), dateadd (minute,sum(tiempo),'1900-1-1 0:00'), 114) as time_hours,
SUM(time)* 0.95 as time_discount
from table
Select tiempo as time_minutes,
CONVERT(varchar(5), dateadd (minute,tiempo,'1900-1-1 0:00'), 114) as time_hours,
tiempo * 0.95 as time_discount
From (
Select Sum(tiempo) as tiempo
from table)a

Hey - I am trying to create a procedure that will retrieve information from multiple SQL Servers. For example, I want to use a select statement on a systems table. Instead of running it from each server, I would rather run it from one and get info on all the servers. To do this, I know that i can 'link' a Server and then make select calls to that server. Some of the other administrators have expressed concern with this. Are there issues that I should research before linking servers. Is there a better way to do what I want to do? Any Input would be appreciated.

For some reason my SQL Server slows down throughout the day for no apparent reason..
The database is 100 gig transaction replicated to 2 data warehouses.
Ive done the usual stuff like monitoring processes killing off blocking transactions but it doesn't seem to do the trick.
There are no jobs running at the point of slow-down so at this current time I am a little lost.
Is there some way to determine why these slow-downs are happening ?
The system becomes completely un-responsive during these periods !!
HELP !! :eek:

Hi all,
I am just wondering is there any other ways to execute an integration service package other than using sql server agent, dos command and manually execute the package in BIDS? I am thinking of running the package on web, is this possible?
What I am trying to do is let user to run the integration service when they need to, so instead using SQL Server Management Studio to run the task being set in SQL Server Agent, I am thinking of something where user can log into a website (like the report server) and then run the integration, so that the data for the report server's reports are being update. Please help out if any know a solution to it. Thanks in advance.

Hello.I would like to learn all the possible ways that we can access and modify data in ASP .net 2.0 programmatically.for example one way would be like this: StringBuilder sql = new StringBuilder();sql.Append(" SELECT *"); //count the total number of recordssql.Append(" FROM dbo.tblJobTitle "); //get the connection string from web servicesstring strConnection = new sqlconnection.SQLConnection().GetSQLConnectString(sqlconnection.SQLDSN.SCIC);//Use the Microsoft.practices SqlDatabase object to execute our sql.SqlDatabase SqlHelper = new SqlDatabase(strConnection);SqlDataReader reader = (SqlDataReader)SqlHelper.ExecuteReader(CommandType.Text, sql.ToString());the i can loop through reader and get the data OR I can create a DataSet like this: SqlDatabase db = new SqlDatabase(strConnection);
DbCommand dbCommand = db.GetSqlStringCommand(sql.ToString());
DataSet dst = db.ExecuteDataSet(dbCommand);I want to know if there is a comprehensive book explainaning all these possible ways to access and modify data using C# under ASP .net 2.0I really really apreciate this.Thank you very much.

I am learning the Optimizer from the book "Querying Microsoft SQL Server 2012" for certificate exam 70-461. I really cannot understand how it explains the number of possible ways to execute a query joining three tables. the pseudo-query is:
SELECT A.col5, SUM(C.col6) AS col6sum
FROM TableA AS A
INNER JOIN TableB AS B
ON A.col1 = B.col1
INNER JOIN TableC AS C
ON B.col2 = c.col2
WHERE A.col3 = constant 1
AND B.col4 = constant2
GROUP BY A.col5;
The book says:"Start with the FROM part. Which tables should SQL Server join first, TableA and TableB or TableB and TableC? And in each join, which of the two tables joined should be the left and which one the right table? The number of all possibilities is six, if the two joins are evaluated linearly, one after another."
Q1: How could it be six possibilities? From my understanding, lets say, if the SQL Server has to join A and B first, and then join C, in this case I can think of 4 possibilities, which are:
1. When A Join B, Left: A, Right: B.
When Join C, Left: result of A join B, Right: C
2. When A Join B, nbsp;
When Join C, nbsp;When A Join B, nbsp;
When Join C, nbsp;When A Join B, nbsp;
When Join C, "line-height:13.5px;">
Q2: The section following the previous question says there are 4 different types of join.."This already gives four options for each join. So far, there are 6 x 4 = 24 different options for only the FROM part of this query."
How can it be 6 x 4? My understanding is 4 is only for 1 join, but in our case, there are 2 joins, so it should be 6 x 4 x 4.

I have a table (F_POLICY_TRANSACTION).This table has a couple of million rows in it.I am using a column named POLICY_TRANSACTION_BKEY to select records to delete (approximately 750k using the code below)This column has a non-clustered index applied..This is the code I have used:
WHILE 1 = 1
BEGIN
DELETE TOP(50000)
FROM F_POLICY_TRANSACTION with (tablockx)
[code]....
Problem is, it takes around 10 minutes to run.Is there any way it can be made more efficient?I have tried varying the rowcount with no success

Hey all!
Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.
To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.
On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.
I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.
Thanks in advance,
Johan

Hi all,
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT
fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE
CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.
any workarounds for this ?

When you use "Alter Table add Column", it adds the column to the end of the list of fields.
How do you insert the new column to position number 2 for instance given that you may have more than 2 columns?
Create table T1 ( a varchar(20), b varchar(20), c varchar(20))
Alter table add column x varchar(20)
so that the resulting table is
T1 a varchar(20), x varchar(20), b varchar(20), c varchar(20)
Can this be done programmatically?

Hi I’m trying to alter a table and delete a column I get the following error. The object 'DF__Morningst__LastU__19EB91BA' is dependent on column 'LastUpdated'.
ALTER TABLE DROP COLUMN LastUpdated failed because one or more objects access this column. I tried deleting the concerned constraint. But the next time I get the same error with a different constraint name. I want to find out if I can dynamically check the constraint name and delete it and then drop the column. Can anyone help.IF EXISTS(SELECT 1FROM sysobjects,syscolumnsWHERE sysobjects.id = syscolumns.idAND sysobjects.name = TablenameAND syscolumns.name = column name)BEGIN EXECUTE ('ALTER TABLE tablename DROP CONSTRAINT DF__SecurityM__DsegL__08C105B8')EXECUTE ('ALTER TABLE tablenameDrop column columnname)ENDGO

ID Mail_code
111111 XNT
111111 N11
111111 XNC
222222 XNC
222222 XNL
333333 XNC
So, if there is any ID that has a value of XNC, I want to exclude the ID all together from my output regardless of the other values.
