View 3 RepliesHi....I execute select statement on three tables and i get the following table:
ID
Value
Name
1
10
color
2
20

3
30

4
40

I have a simple query which is taking about 2.5 minutes to execute. What can be done to speed it up ? I cannot change the table structure. even without the group by, and without the float and division, it takes about 2.25 minutes.
Select 'SV00302' as FileSource,
[Service_Call_ID],
sum(0) as ActualHours,
sum(cast([Estimate_Hours] as float)/100) as EstHours,
max(MODIFDT+Modified_Time) as ModifiedDateTime
[code]...
Hello,I have created the following trigger:CREATE TRIGGER tr_UDFTest ON UserDefinedFields FOR INSERT, UPDATEASDECLARE @foobar varchar(100)SELECT @foobar= foobar FROM insertedIF ( @foobar = 'foobar') INSERT INTO LogTable (LogText) values ('Found foobar')ELSE INSERT INTO LogTable (LogText) values ('Did not find foobar')GOBasically, the trigger monitors the values begin put in the foobar field,and acts accordingly based on what it finds. In practice, my needs are abit more complex (the trigger will be programmatically generated, based ona set of rules) but the principle is much the same.ErrorTable is defined as :create table LogTable (LogText varchar(128))UserDefinedFields is a table whose definition may change depending on theuser's needs, but for now assume it contains a varchar column calledfoobar.My problem is that if the user's needs change, and they remove the fieldfoobar, the trigger causes all subsequent inserts/updates to fail with anerror indicating the column foobar doesn't exist. (Which makes sense ofcourse!)CREATE TRIGGER tr_UDFTest ON UserDefinedFields FOR INSERT, UPDATEASDECLARE @foobar varchar(100)if not exists (select * from syscolumns sc inner join sysobjects so on sc.id = so.idwhere sc.name = 'foobar'and so.name = 'UserDefinedFields') BEGININSERT INTO LogTable (LogText) values ('Error : Foobar column does not exist!')RETURNENDSELECT @foobar= foobar FROM insertedIF ( @foobar = 'foobar') INSERT INTO LogTable (LogText) values ('Found foobar')ELSE INSERT INTO LogTable (LogText) values ('Did not find foobar')GOI'd be happy with the above 'flavor' of solution (bailing, or logging anerror and bailing, when we hit unexpected problems) as long as theinserts/updates don't fail otherwise. Perhaps I can nest a transaction, orsupress a RAISEERROR or something?The cleanest solution would probably be to change a bunch of clientsoftware such that it won't remove the foobar field if this field isneeded for a trigger (foreign key constraints based on the set of rulesI'm using are a nice and intuitive solution). Unfortunately, that doesn'twork well with my timeframe (done by thursday) as changing the clientsoftware is impossible by then. Any ideas or suggestions? Platform isWin2k, SQL 2000 Enterprise (I think enterprise, certainly 2000).thanks,Dave

Say you have an existing populated SQL 2005 database, with 700+ tables, and you want to just change the order of the columns inside every table. Short of manually building conversion scripts, anyone know an automated way to do this? I was thinking thru ways to do them all in one shot, and have tools like Erwin and DbGhost that could be used also. Basically moving some standard audit columns from the end of the tables to just after the PK columns.
Thanks, Bruce
I have set up mirroring in high availability mode (principal, mirror, and witness).
After setting up mirroring, I needed to adjust the size of a column in one of my tables. I did so with the following command
ALTER TABLE OrderOptimizer.dbo.rCodes ALTER COLUMN CodeDescription VARCHAR(8000).
The column was initially VARCHAR(128)
When I look at the table structure it shows that the column is now VARCHAR(8000), however I can only enter 128 characters into the field.
I forced a failover to look at the table on the mirrored version. It too showed that the column was VARCHAR(8000).
If I open the table I can enter more than 128 characters into the field, however when I refresh, it is truncated to 128 characters,
Any help would be appreciated
Change structure of a User Defined Table Types
field
([idConteudo] [int]
NULL) to
([idConteudo] [BigInt]
NULL)
Or really should drop and create again?
CREATE TYPE [dbo].[tbProjeto] AS TABLE(
[dsConteudo] [varchar](64) NOT NULL,
[idConteudo] [int] NULL,
[dtConteudo] [datetime] NULL DEFAULT (getdate())
)
GO
With the Synonym, I was encouraged to separate my db to several smaller dbs, like base,dynamic,static and security. Now I am trying to use mirroring, I see it may cause problem, I think I need mirror all them to another server. My question is when the server is down, will all db switch to mirror server in the same time? And one can manually set which db is the principal db, but in my case, it will not work if principal server of all four dbs are not the same.
Any thought?
thanks
I have a database (MSSQL). To demonstrate the problem let me show a fictive Tablestructure. I don't want to discuss about how to save the data differntly, because the structure is fix and I can't change it.To get this result I would do a sql query with a lot of joins like that:
SELECT firstname, lastname, email.value, phone.value
FROM Customer
INNER JOIN
(
SELECT Customer_Properties.id, Customer_Properties.value
FROM Customer_Properties
[code]...
I don't think that this is really performant and the SQL-Queries get very complicated. Give it a other methode for that? I can't change the data structure.
hiI want to increase a varchar(5000)to varchar(8000) on a table thathas approximately million rows.....What is the impact on the serveror any good recomendations of a action to accomplish this in the best andfastest way.thanks davep
View 4 Replies View RelatedAs the title suggests we are looking to change the service account of a SQL mirror implementation. I will be using the same account on all 3 servers involved in the configuration.
I know each server requires the account of the other two adding but as this will be the same account I assume this doesn't apply?
Also for mirrored databases already set up would I need to reconfigure the security for each one?
Is there anything I am missing?
We have a database in SQL Server 2008 R2 with mirroring and want that replication is done by dedicated network.We stop the endpoint and when we try to run the following command, syntax error occurred:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '192.168.1.14'.
What is the correct syntax of the command line below?
ALTER ENDPOINT Endpoint_Mirroring AS TCP (LISTENER_IP = '192.168.1.14')
Hello friends,
I am new to the SQL Server 2005 development.
From last 1 week or so, i have been facing very strange problem with my sql server 2005s database
which is configured and set on the hosting web server. Right now for managing my sql server 2005 database,
i am using an web based Control Panel developed by my hosting company.
Problem i am facing is that, whenever i try to modify (i.e. add new columns) tables in the database,
it gives me error saying that,
"There is already an object named 'PK_xxx_Temp' in the database. Could not create constraint. See previous errors.
Source: .Net SqlClient Data Provider".
where xxx is the table name.
I have done quite a bit research on the problem and have also searched on the net for solution but still
the problem persist.
Thanks in advance. Any help will be appreciated.
we have a table in our ERP database and we copy data from this table into another "stage" table on a nightly basis. is there a way to dynamically alter the schema of the stage table when the source table's structure is changed? in other words, if a new column is added to the source table, i would like to add the column to the stage table during the nightly refresh.

DELETE

I don't want to create this #rev table so that i can avoid the delete statement. But data should not affect. Can i rewrite the above as below:
SELECT [Cusip], [sponfID], GroupSeries, [tran], [AddDate], [SetDate], [PoolNumber], [Aggregate], [Price], [NetAmount], [Interest],
[Coupon], [TradeDate], [ReversalDate], [Description], [ImportDate], MAX([fi_gnmaid]) AS Fi_GNMAID, accounttype, [IgnoreFlag], [IgnoreReason], IncludeReversals, DatasetID, [DeloitteTaxComments], [ReconciliationID],

Any hints how to incorporate these outstanding items?

I'm new in creating tables. and I was asked to create table(s) to capture information using SQL server 2005 (express edition)
please read below and share your thoughts and opinions o what's the efficient and best way to structure the tables.
I need to capture user's input daily and every hour, text can be from 20-100 characters, and my company is expecting to have 50,000+users in the future...Also the hrs's text can be stored for max 120 days, after that data would be deleted from the table(s)
An example is put all together, (not sure if it is the right and efficient way)
An example is put all together, (not sure if it is the rigth and effectient way) and if database would support that.. and if it will be fast enougth to search for data
(table structure) - (example with 3 users)
userId | timestap | message
1 12/12/2007 10:00 some message
1 12/12/2007 11:00 some message

Hi,
I have one field "Status" with 15 different types of values. Like 1, 2, 3, 4 .. 15.
Now this Status field contains the values like this:
Id Status
1 1,2
2 3
3 1,2,3
4 13,15
What is the best way to organize this information in SQLServer table?
My idea is Create one table with the following volumns: ID, Status1, Status2, Status3, ... Status14, Status15.
Now the above data look like this:
Id Status1 Status2 Status3 ... Status13 Status14 Status15
1 1 1 0 0 0 0
2 0 0 1 0 0 0
3 1 1 1
4 0 0 0 1 0 1
So, In future If they add new column they can easily add column like status16.
And status table look like this
Status
StatusID Description
1 a
2 b
..
15
Thanks in advance
All,On my aspx page i have 2 sets of checkboxlists, each with a number of items and i am storing that info in my db. currently i have my table set up this way: InfoID--PK autoUserID-intCheckBoxList1ID-intCheckBoxList2ID-int So a user can select more than 1 item in each checkbox, so this table will contain multiple user-ids and each id from the respective checkboxes. My question is, is there a better way to store this data? I hope this is clear, any input would be greatly appreciated.Thank you.
View 2 Replies View RelatedHi,I have a table for storing my picture albums here it is:CREATE TABLE [UserAlbum] ( [ID] [int] IDENTITY (1, 1) NOT NULL , [UserID] [int] default(0) , [AlbumName] [nvarchar] (100) NULL , [Audience] [int] default(0) , [Date_added] [smalldatetime] NULL , CONSTRAINT PK_CmmNet_userAlbum_ID PRIMARY KEY CLUSTERED ( ID )) ON [PRIMARY]GO
it has a field called "audience" as the name defines i want to choose who will see my albumsit is integer and as follows:0 value=everyone1=friends only2=private
as i started to write a query for it i came into this problem: for exampleif i write SELECT * FROM UserAlbum where audience=1 then only friends can see the infowhat happens to everyone with value of 0?when i set it to 0, friends should also be able to see the info because it is set for everybody
i noticed i should use "in cluase" like thisSELECT * FROM UserAlbum where audience in ('0','1') > so in this way both everyone and also friends can see the info
or maybe i should add 3 different fields for private,public,friends
it seems to be simple but at the same time harddoes anyone have a suggestion?
Hi i have a student table and also an societies table, and a student can belong to as many societies as possible, for example student John Taylor belongs to the Football society, rugby societey and dance society, where as student Jim Jenkins belongs to the Football society, rugby society, arts society and graphics society.
My tables so far look like this;
STUDENTS; student_id, student_name
SOCIETIES; society_id, society_name
My question is how can i make the scenario above reflect in my table structure, would i need to create another table, if so what fields or columns should i place in this new table, thank you.
I'm a VB.net programmer working in an environment that doesn't have a true sql db administrator. We have a situation where we're thinking about adding a new database (db2) with the same Tables used in an existing database (db1). We were hoping to avoid this, but circumstances are forcing us to think about it. Are there any sql tools out there to maintain a dual-db like this? What are the main disadvantages to this?
