How can we say whether the SP is successfully compiled or not if we are compiling it on the server as a part of the TSQL script since it does not throw any message like ORACLE does.
In oracle, system will let you know whether the the procedure is successfully complied or not?

I have a task to perform a new SQL Server 2005 installation at a client.
They have a system with 10 external SCSI drives, each of 72GB. They only have one database of 80GB in use at this system.
1) Userdata: I think that I will put 5 disks at SCSI channel 1, with RAID 3 or 6, with formatted space of 140GB.
2) Log: I think that I will put 3 disks at SCSI channel 2, with RAID 5, with formatted space of 70GB.
3) TempDB: I think that I will put 2 disks at SCSI channel 3, with RAID 0, with formatted space of 140GB.
System already has two built-in drives (RAID 1) for operating system, where I think I will put system databases.
I am open for suggestions and improvements!

I am working with a client who has all databases, logs, tempdb and user/system databases on a single raid set.
In order to make some speed improvement, we have decided to move log files to a second raid controller card.
To accomplish this, we are thinking about taking these steps:
1) Detach database XYZ.
2) Stop database service.
3) Create a new partition on new controller card.
4) Copy old log files from I: to new K: drive.
5) Remove drive letter I: from system.
6) Change drive letter K: to I:
7) Attach database
My question is, does SQL Server recognize the log files automatically, since they are placed at same logical position (i: drive)?

Just a thought.
If an issue is resolved please note that the problem has been resolved. Because there are "many ways to skin a cat" it would be helpful to anyone else with a similar problem (or someone trying to learn) what the solution was.
Hello all,
I have 2 primary key fields the ssn and refnum... if the data in the file is duplicated it will not import to my table rights even though i am using DTS to do my import, correct? or do I need to add an extra validator in there?
We have a project at work that requires us to run an msde database from cd. My sup. and I disagree on if this can be done or not. We currently have an application written in asp that uses an access db. We copy the *.mdb file and all the asp files to cd and use the app. to query the db. Now, we have a client who wants the same capability only using msde. They will not allow us to install the full version of sql on there machines. No one in the dept wants to re-write this app. so we're trying to figure out if we can make it work with msde. So, My first question is, does anyone think that it is possible to just copy the *.mdf file to cd (mind you WITHOUT the *.ldf file... can't write to a cd)andMy second question is, can a sql db run without both files in any situation(mdf,ldf)? (I believe this is impossible, but would like to here it from someone with more experience)Any comments are greatly appreciatedthanks

I am about to write my registration confirmation tables.
Right now I have my registration form and table "Users"
that receives input from user registration.
I want to do email confirmation of a registered account.
I was thinking of doing this by creating a table "Verify"
that is set to 0 if not verified and 1 if the user verifies
his email address.
Then I started thinking about the original registration
information. If a user "doesn't" verify, then there is all
this dormant data in the "Users" database. So, maybe
it is better to write all the registration data to the "Verify"
table and then have SQL move that data to the "Users"
table upon verification? This sounds a bit sloppy to me...
is this how the email verification of data is done or, if
not, can somebody suggest a best practice?
I thank you.
I need confirmation from you SQL Server experts out there. Please let me know if the following works. Thanks!
This stored procedure gets a value and increments by 1, but while it does this, I want to lock the table so no other processes can read the same value between the UPDATE and SELECT (of course, this may only happen in a fraction of a second, but I anticipate that we will have thousands of concurrent users). I need to manually increment this column because an identity column is not appropriate in this case.
BEGIN TRANSACTION
UPDATE forum WITH (TABLOCKX)
SET forum_last_used_msg_id = forum_last_used_msg_id + 1
WHERE forum_id = @forum_id
SELECT @new_id = forum_last_used_msg_id
FROM forum
WHERE forum_id = @forum_id
COMMIT TRANSACTION
Hi to alll of you, i'm working in a project to save cars information, when the user who adds on the new record enter all the data, this will need to be printed with a particulary number, which needs to be unique, (lets take a passport number as an example) this generated number will takes some info from the filling fields, for example:
Cars Brand: BMW (catalog number: 120)
Cars Model: 325 (catalog number: 30)
Year: 2008 (catalog number: 18)
So the unique certification number will takes from the catalog numbers * 20 / 5 for example for cars Brand
for Cars Modelo: catalog number *3 + 15
CERTIFICATE NUMBER: 480-105
I'm not sure if this is possible.
I will realy thanks for your help in this issue.

Hi.
I have set up my confirmation system to work as thus:
1) user registers
2) registration goes into a temp table with a code
3) user gets a MD5 code in his inbox
4) user clicks back
5) click-back page moves registration data from TEMP table to USER table and sends the user to the signin page.
6) ...
Now, my question is - how do I handle this final step in account
confirmation? Should the first signin act as a final confirmation of
the users account? This makes sense. Should the data in the USER table self-delete after a day if there has been no first sign-in? Should I have a column in the USER table to show if the first login has happened? How should I do this?
I am sure I could mess around with this but it would be great to
get feedback from somebody that has done this multiple times and has a sense of what the best practice is (based on large volume examples).
Your feedback is much apprecaited.
Thanks.
Hello,
I am looking for some confirmation on a behavior of the SSIS Script Task. I have a custom script task that takes an input file, and archives it after it has been processed into the database.
When I run this package in the Visual Studio GUI, if the destination drive is full, it throws an exception telling me that there is not enough disk space. So, my questions are:
1) If this happens when the package is running through the command line, would this exception still be thrown? (I am thinking it will be)
2) Also, Do I need to explicitly fail the script task in the event handler, in order to ensure this .Net exception being thrown will cause the component to fail. (I am fairly certain I do, since this is what I had to do inside of the Visual Studio GUI, but does anyone know if this same behavior would occur when running from the command line?)
Thanks,
Chris

View 3 Replies View RelatedUsing small stored procs or sp_executesql dramatically reduces the number ofrecompiles and increases the reuse of execution plans. This is evident fromboth the usecount in syscacheobjects, perfmon, and profiler. However I'm ata loss to determine what causes a compilation. Under rare circumstances theusecount for Compiled Plan does not increase as statements are run. Seemsto correspond to when there is no execution plan. It would seem to me thatcompilation is a resource intensive task that if possible (data and schemaare not changing) should be held to a minimum.How does one encourage the reuse of compile plans?Is this the same as minimizing compilation?Looks like some of this behavior is changing in SQL 2005....Thanks,Danny

Hi,
I would like to know if the execution plans of stored procs also get migrated when we do migration to 2005 from 2000 using attachdetach method or we will need to re-run the stored procs?
The thing is when I am running the Stored procs in 2005, its performing really slow in first run.
Any help in his regard is highly appreciated.

Hi all,
I€™m having a test regarding to the image data type. The test program is written with sql native api and just update the image data type column, but I looked the SQL Compilations/sec and Batch Requests/sec counters in SQLServer:QL Statistics using Perfmon, both values are almost the same. It seemed whenever the stored procedure is called, SQLServer compiles it and makes execution plan again. But when I had a test without image data type, SQL Compilation/sec was 0. SQL version is Microsoft SQL Server 2005 - 9.00.3054.00 (Intel X86) (Build 2600: Service Pack 2).
Is SQL server working the way expected or am I missing something?

View 1 Replies View RelatedI am wondering something, once we've created a job that executes a package at a given time interval, does that package get recompiled each time the job spins up and executes the package? Or is the package compiled once and then that compiled code is executed each run after the first run?
What I'm seein is this; I have a package that reads data from flat text files and then dumps that data into the database. The package will take 3 minutes to execute when executing on a single file, but when it's looping through ~50 files, it will take ~30 minutes to execute, that is less than a minute per file. Why is this?
Hopefully I'm just forgetting something and not setting a checkbox or radio button somewhere. The job is set up as an SSIS job, not as a command line job.
Thanks in advance for any help you can give me.

I have discovered what looks like a bug in the optimiser. I've posted it at https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=288243 but I wonder if any of you with SQL 2005 RTM, 2005 SP1 or 2008 CTP could confirm when this was introduced and whether it is still an issue?

I have the following UNION ALL query with SELECT INTO @tblData temp table. I would like to confirm if my query is correct.
In my first SELECT statement, I have INSERT INTO @tblData.
Do I need another INSERT INTO @tblData again in my second SELECT statement after UNION ALL?
DECLARE @BeginDate as Datetime
DECLARE @EndDate as Datetime
SET @BeginDate = '7/1/2015'
SET @EndDate = '7/13/2015'
DECLARE @tblData table

I've been looking over this and can't see anything wrong. Can anyone shed some light on this for me?

I am re-writing old DTS packages(from sql 2005) to convert them to SSIS packages(sql 2014) and in one of the script task, the old activex script does not run.
The script is :
'************************
' Visual Basic ActiveX Script
'************************
Function Main()
mydate = now()
yrs = ""
mth = ""
mth = Month(mydate) - 1
yrs = Right(Year(mydate), 4)
If Month(mydate) = 1 Then mth = "12"
[code].....
Not sure how to proceed forward? I am quite new to package migration
I have an application that is moving from an home made full text search engine to using the full text indexing engine of SQL 2005. I have a stored procedure that I want to behave as:
check documents table to determine whether a full text index for SQL's full text engine has been created.
If it has not, query the documentText table (which is the table for my in-house full text search)
If it has, use the full text indexing engine
My problem is that compilation of the TSQL to create the stored procedure fails when the full text index has not already been created with the followign error:
Msg 7601, Level 16, State 2, Procedure My_FullTextSearch, Line 0
Cannot use a CONTAINS or FREETEXT predicate on table or indexed view 'Documents' because it is not full-text indexed.
In my test lab, I tried:
1. creating the full text index
2. creating the stored procedure
3. deleting the ful text index
which gets me to the desired end result of having a stored procedure that can determine whether or not the full text index has been created yet (the procedure works in this state). But I creating this index as part of this stored procedure creation in production is not an option.
My question - Can I somehow tell SQL to ignore the compilation errors it encounters while creating this stored procedure? If not, is there some other way to create this "smart" stored procedure?
Here's a code snippet stripped down to the bare minimum to generate the error:
CREATE PROCEDURE [My_FullTextSearch]
@Term VarChar(1000)
AS
BEGIN
SET NOCOUNT ON;
IF NOT OBJECTPROPERTY(OBJECT_ID('Documents'), 'TableHasActiveFulltextIndex')=1
BEGIN
Select [DocumentID]
from [DocumentText]
where [Term] like '%' + LTRIM(@Term) + '%'
END
ELSE
BEGIN
Select [key] from FREETEXTTABLE(Documents, Contents, @Term)
END
END
To minimize the very large number of stored procedures typicallyassociated with an application, I have gotten in the habit ofcombining a select, insert, update, and delete all in one procedure,and passing an argument to indicate which to use. (I use defaultvalues for all input params to avoid having to declare them forselects and deletes.) So I'll have just one PersonAdmin proc insteadof PersonGet, PersonInsert, PersonUpdate, and PersonDelete procsWhile this is nice for housekeeping, I wonder what the compiler doeswith such an architecture,and I fear the worst. The select returns arecordset; the others don't.Is this a bad idea?If it is, I really wish SQL would permit some sort of user folderstructure in the proc list.

I have 2 questions to ask:
1) How can I fix this Compilation Error BC30451: Name 'SqlDataSource3' is not declared?
2) I just read MSDN Visual Studio 2005 Technical Article "Data Access in ASP.NET 2.0" and I saw the following thing:
Types of Data Sources:
SqlDataSouirce: The configuration of a SqlDataSoure is more complex then that of the AccessDataSource, and is intended
for enterprise applications that require the features provided by a true database management system
(DBMS).
I am using the website application in VWD 2005 Express to do the task of extracting data values from the Tables of SQL Server 2005 Express via .NET Framwork, ASP.NET 2.0 and VB 2005 programming. Can VWD 2005 Express be configured to SQL Server 2005 Express (SQLEXPESS) for the SqlDataSource connection and do the data-extraction task via DataView, CType Function and the Page-Load procedure?
Please help, respond and answer the above-mentiopned 2 questions.
Many Thanks,
Scott Chang
In my SQL Server, I see the below message in the Application Event Viewer
"18265 :
Log backed up: Database: HSD, creation date(time): 2007/01/06(05:05:05), first LSN: 1439:495055:1, last LSN: 1439:496675:1, number of dump devices: 1, device information: (FILE=1, TYPE=DISK: {'D:MSSQLBACKUPHSDHSD_tlog_200707141300.TRN'})."
When I save the application event viewer and open it in another server, I do not see the above message, instead I get the following message:
" Can't find or load message DLL. Message DLL must be in path or in current directory."
Any thoughts to overcome this problem is appreciated.
Thanks

I run SB between 2 SQL servers. In profiler on an initiator side I see next error: 'This message could not be delivered because its message timestamp has expired or is invalid'. For the conversation we use best practice, i.e. target closes a conversation. Target side succeed to close conversation, but initiator still stay in DO (disconnect_outbound).
What is a reasone for the error? What to do?
