Placing MSDE .mdf And .ldf Files On Seperate Drives.
Mar 5, 2005
Hi,
I know that SQL Server (MSDE), databases run much faster when the data and log files are on seperate physical devices. I can do this explictly when I write a CREATE DATABASE SQL script, but would like to change the MODEL database so that all new databases use the sperate data/log file assignments by default. I haven't found a way to alter the sysfiles table in model - I can read the data, but it balks at trying to update it. (recordset is not updateable, or adhoc querries not allowed against a system database).
I didn't see any options on the MSDE install that implements seperate data/log paths.
I don't have the SQL Server tools (like Enterprise Manager) available, but I do have VS.NET 03 (Standard). And Web Data Administrator.
Any suggestions? Thanks in advance.

I am working on deploying my production DB's to a new server and am looking for some advice. The new server is running RAID-5 (the old one is RAID-0) but it only has one controller therefore I can not create another array group. So I was wondering since the disk setup is C: and D: (Virtual Drive) if I would see any benefits from placing my log files on C: and my Data files on D:?
The other question is related to the size of my log files. Some of the DB's were not created by me and there are no constraints in log file growth causing some very large TRANS logs. For example, there is a 100 MB DB with a 1 GB trans log. I restored the DB on my new server and truncated the log file (manually, the Ent Mgr Shrink DB tool doesn't work worth a hoot) to half the size of the DB and it functions properly. I was just wondering if this would cause any problems down the road if I did all of my DB's like this?
I am restricting log file growth to approximately half the size of the DB.
There is one DB that is 1.5 GB and the log file was set restricted to 2mb and it works fine, but I feel that I should bump this up a bit.
Any recommendations?

Hi, Gurus, I am running SQL-Server 2000 on SCSIIs with Raid-5. Three disks. I see only one Logical Disk with 3 partitions. Since it's recommended to have Log files seperate to Data files physicially, currently both exist in the D-Drive. How can it be accomplished?
Another question for ur kind suggestion. I have a merge-repl setup. Publisher and distributor at the same machine. One subscriber over the internet. Replication works through VPN rather that FTP. Whenever i apply SNAPSHOT it takes more that 12 hrs to replicate the 2 GB DB. Although VPN is more secured but the tunneling makes the replication rather slow i guess. Will there be a major difference if i open the default port of ftp on the ISA and change the subscriber to get the SNAPSHOT as Anonymous Subsciption. I mean What's better, Security VS Performance. During the SNAPSHOT the Web-users running on the Subscriber wait for the latest data which is very much annoying.
Another question please, I wanna replace the current publisher-DB machine with a new Hardware-Machine. I don't wanna lose Replication and re-running the SNAPSHOT. Is it possible to retain the publication by restoring the Master, Publication and Distributor respectively on the new machine. The new machine will have the same Operating system name and configuration.
Regards!!

Hi everyone, I have a small dilema here. I am running SSRS 2000, and I have a report that is grouped by Part Number. I have =Fields!Formula.Value < .1 so I can view only what is greater than .1 Well, my problem is that when I put it under the group Visibility properties, it does not pull all the data. and if i put it under detail Visibility. It does show me everything but any Part Number that is less than .1 shows just the part number but no detail. How can I make my report show all my data but without leaving data out????
Thanks ahead of time,
Abner

I have a stored procedure that takes various parameters and performs simple selects using these. A quick summary of the db structure this is working on would be :
lookup_table1
table1_id
description
lookup_table2
table2_id
description
This stored procedure attempts to select the given description from the given table and return the id, if the id isnt present it then inserts the new value and returns the new id.
Now I have this working, ish, but the problem that I have is that in the case of a new insert the procedure returns two datasets, an empty one (as the initial select returned no results) and another with the id of the newly inserted value.
This procedure as it stands right now
CREATE PROCEDURE aida_lookup
@lookup_table varchar(255),
@lookup_id_name varchar(255),
@lookup_description_col varchar(255),
@lookup_value varchar(255)
AS
declare @sql nvarchar(2048)
--
-- Check if the given lookup value exists in the give table / column
--
set @sql ='SELECT ' + @lookup_id_name + ' FROM ' + @lookup_table + ' WHERE ' + @lookup_description_col + ' = ''' + @lookup_value + ''''
EXECUTE sp_executesql @sql
if (@@rowcount = 0) goto new_value
if (@@error <> 0) goto on_error
return(1)
--
-- Insert new lookup value into the given table / column
--
new_value:
-- NEED TO CLEAR PREVIOUS NULL SELECT
begin transaction
set @sql = 'INSERT INTO ' + @lookup_table + ' (' + @lookup_description_col + ') VALUES (''' + @lookup_value + '''); SELECT SCOPE_IDENTITY()'
execute sp_executesql @sql
if (@@error <> 0) goto on_error
commit transaction
return(1)
--
-- Error handler
--
on_error:
rollback transaction
return (0)
GO
The problem being is that if the value is inserted as a new value I need to remove the empty dataset so that regardless of how the procedure is run, it will always return the id at position row 0 column 0.
My attempted solution was to declare a @temp var and place the return value of sp_executesql into this, and if it wasnt null then return it, and if it was then proceed to insert, e.g.
declare @temp int
...
SET @temp = EXECUTE sp_executesql @SQL
if (@@temp = null) goto new_value
SELECT @temp
return(1)
Obviously this doesnt work, so I am open to suggestions. To be completly honest I have run out of hair to rip out and I am sure this can probably be done in a much more elegant fashion, so any help will be greatly appreciated

Our development server is limited on RAM and I have been asked to increase Tempdb. I made the decision to put it back on disk; something I have done dozens of times before. I have used the Enterprise Manager`s GUI interface and I have manually typed in the SQL using ISQL/w, both ways have resulted in the same error message.
Microsoft SQL-DMO
Error 5016: [SQL Server] Incorrect database name or device name(s).
I have dropped the old and created new database devices (with different names) and I still receive the error message. I have even tried rebooting with Tempdb back in RAM and on disk 1t 2MB (which works). And yes, I HAVE checked my typing.
I would GREATLY appreciate any ideas on what may be wrong. The system is 6.5 with SP4 on Win NT with SP3. I inherited the system, so I am not certain what the hisory is.
Thanks,

I'm generating emails using sp_send_dbmail. Everything works perfectly except for one thing. In the body of the email I need to show a link to a web page (eg http://myweb/login.aspx).
The problem is that the received email shows the "link" as plain text, ie it is not a clickable link. I've tried adding char(13) (and char(10) and both) after the link text but that doesn't help.
Is there a way to make the link text a real link when received by Outlook? (All recipients will be using Outlook if that helps).
Thanks,
John

I have been requested to add the sum of an interger field to the table header. I have the sum in the footer (which is very easy to do), but I cannot get the sum to appear in the table header.
I then set-up the stored procedure to run the sum, and place it into a dummy field. I still cannot add this field to the table header. Instead of printing the data for the dummy field (the correct total), it instead prints the actual field name on the report.
Is there anyway to place a sum in a table header on a SQL Server Report?
Let me know.
Thank you,
T.J.

Hi,
After exporting the report the column headers in the rreport should not scroll, it has to fix with report headers. If i move the column headers to report header the columns are merging in excel, some columns are hiding.
For ex: I have 10 columns, it has to take from A to K but it is taking A to P. one column is occupying two columns. how to avoid this merging and how to place the column headers in the report header.
Thanks

I've read that if particular tables are frequently queried together through a join then these tables should be placed on different devices on different physical disks.
What does this mean exactly and how would you configure this?
Is this a common practice in high-performance real-world environments (or should it be)?

Hello folks,first of all I really don't know how you gurus call this way ofwriting joins:SELECTA.FIELD,B.FIELDFROMTABLE_A A,TABLE_B BWHEREA.ID_FIELD = B.ID_FIELDI find this way very useful and readable. It works also with left andright Joins (using *= or =* instead of = )A friend of mine found that the inner join way (using = ) in Access ismuch more slower than using the classic INNER JOIN TABLE ON FIELDsintax. My question is: was MSSQL Server studied for using the shortway, or it is just a workaround found by someone? Is there aperformance degrade folllowing this way?TIA,tK

I have a question regarding saving hashtags in another table. I have two tables with these columns:
Table1
ItemId, Name, Description (it may contains several hashtags like this example "hey I am an #example of this #question")
Table2
HashtagId, ItemId, Hashtag
So I want to detect #example and #question and put them in Table2. I'd like to create a trigger for table1 that if there was a hashtag, it added a record in table 2.
CREATE TRIGGER [dbo].[tr_Events_ForInsert_Hashtag]
ON Table1
FOR INSERT

DECLARE @ItemId bigint

Hi everyone, I have created a matrix report which takes 3 parameters being store, year and quarter which then displays budget information in a matrix. This all works fine but I would also like to have a bar chart below the matrix to visually show the results.
However when I add the bar chart and add the relevent dataset details etc the chart does not appear when I preview the report. I wondered if the chart wasn't showing because the parameter values are not being passed to the chart.
Has anybody any idea of adding charts to reports in this way or knows of any instructions to do so.
Thanks

This one is driving me crazy. I have followed several steps given in examples both online and in the four SRS books I own to no avail. I have created a new report.rdl template and have all the required features for our company needs, except placing the company logo as a background image in watermark style (similar to the Company Sales report that comes with the SRS report samples). I right-click on the body and in properties set the image name (URHCSlogo), it defaults to external, but I can not get it to be embedded and it will not let me set the mimetype. Could someone please give me a step-by-step method to do this? Thanks!

I am trying to run a program called NVivo7, which - when I install - also requires installation of SQL Server. Because my C drive is small (and nearly full), I am trying to run NVivo7 off my D drive, though SQL seems to install on C. Is it possible, do you think, to use 2 different drives in this way, or do both the program and the Server need to be on the same one? If so, is there any way to get them both on D?

We are in the process of replacing our primary production server. In the process of determining how SQL server is going to be structured, it has been suggested that I place all current and new indexes on a separate file group. These filegroups would then reside on a separate shelf on the server. What are the pros and cons of doing this?

Hi,
If I am taking a Matrix and right clicking on the column header and click on the SubTotal then it always place that column on the right of it .If I want to place that column to the left of my original column then I can't do it.
Adding manual column and then puuting the Expresstion =Sum(Fields!MyCol.Value) is not halping as it will give me the same value that is there in the column instead of giving me the column
-Thanks,

Hi,
I am novice to SQL reporting services.
I have created a report using SSRS.
In this report I would like to show a column value as button and wants to execute vbscript code on click.
Or at least execute vbscript code on click of that field (button is just an option!)
The code will launch another application (exe file or else)
Help in this regard would be appreciated.

So i'm not really new, but got a question. i've recently been looking to to the Western Digital Raptor Drives.
as far as performance, it's always been my understanding that the speed of the hard drive is just about always the bottle-neck of a computer. i'm currently running 2 stripped WD 500gb SATA drives for my SQL server (dual Xeon 2.8 with 2GB memory).
i'm thinking of upgarding to 4 WD Raptors (10k RPM) drives, the new 150GB models. anyone have an opionion? do you think i'll get a large performance increase?
the database that i run queries off of now is about 125 Million names, with about 80 fields in width. so it's rather large, and usally takes a fair abount of time to get my results back (we're talking anywhere from a minute, to half the day.)
do you think the raptors will slim that down significantly?
