Thanx in advance
In our SQL Server database we will have a table that will be populated with about 2000 recordsper day. That is 2000 records per day for 5 days per week. Currently the computer we are using has about 50 gigabytesof available hard drive space on it. We are concerned that maybe we will need a bigger hard drive,based solely on the number of records entered into this table per day. The problem is I don'tknow how to calculate how much hard drive space we need. I think I read that using varchar,sql server 2005 really optimizes a database. Here is a typical example of data in ourdatabase. I put dots on three lines between the first and last sample record to justillustrate that there are many records in between.
Basically we only need 8 months of data at a time in the table and then we can purgerecords older than 8 months.Can someone help me approximate how much hard drive space I might need for 8 months of data,given the following sample record in the database?
Sample: -->34.5 4.08 10.6 .0012
Sample Table in my DB just for illustration:
(PPsquare inch) (Diameter) (Weight gm) (coeffOfSatFriction)
34.5 4.08 10.6 .0012...21.7 3.54 6.22 .019

Hi,
I am running sql server 7 with 200+GB database size. I have one table with following fields
IIINDEX
DOCTYPE
IMAGE BLOB
I need to dump all the information from this table to hard drive.
I have try with delphi ado and delphi odbc (limit 1mb), somehow when I run the program it gives me an error message E_ timeout.
How can I dump this information without using delphi.
Any help will be highly appreciated.
If you have any code that can help please email me samirp@ix.netcom.com
Thanks.

I was assigned a project to read binary data file (2G) and select data from OrderID, OrderDate and Price three columns (there are about 50 columns) into SQL table.
Where to start? Do I need to convert entire binary data file into text file?
hello.
i have a _CommandPtr that has the type CommandTypeEnum::adCmdTex, and the CommandText a query("Select * from Table_1") and this select returns one row that has a binary data in it.
Code Block
_CommandPtr pCommand;
//Create the C++ ADO Command Object
pCommand.CreateInstance(__uuidof(Command));
pCommand->ActiveConnection = this->pConnection;
//Make the ADO C++ command object to accept stored procedure
pCommand->CommandType = CommandTypeEnum::adCmdText;
//Tell the name of the Stored Procedure to the command object
pCommand->CommandText = _bstr_t("select * from Table_1");
//get recordset
pRecordset = pCommand->Execute(NULL,NULL,CommandTypeEnum::adCmdText);
BYTE* buffer = NULL;
if(pRecordset != NULL)
{
while (!pRecordset->GetEndOfFile())
{
VARIANT var = pRecordset->Fields->GetItem("test")->Value;
void * pData = NULL;
SafeArrayAccessData(var.parray, &pData);
long size = GetArraySize(var, NULL);
buffer = new BYTE[size];
memcpy(buffer, pData, size);
SafeArrayUnaccessData(var.parray);
pRecordset->MoveNext();
}
pRecordset->Close();
}
where:
Code Block
long GetArraySize(const VARIANT& var, long * nElems)
{
if ( !(var.vt & VT_ARRAY) ) return -1;
long size = 0;
long dims = SafeArrayGetDim(var.parray);
long elemSize = SafeArrayGetElemsize(var.parray);
long elems = 1;
for ( long i=1; i <= dims; i++ )
{
long lbound, ubound;
SafeArrayGetLBound(var.parray, i, &lbound);
SafeArrayGetUBound(var.parray, i, &ubound);
elems *= (ubound - lbound + 1);
}
if ( nElems ) *nElems = elems;
size = elems*elemSize;
return size;
}
I enter in VARIANT var = pRecordset..... and if gives me a value... but when I put it in Memory explorer in VS, i only see this data " fe ee fe ee fe ee fe ee fe ee fe ee fe ee ...fe ee" and of course it brakes at
SafeArrayGetLBound(var.parray, i, &lbound);
Can someone tell me where I am doing a very bad thing?
P.S. I was able to read the binary data from the server using C#.NET 2.0.
Hi I've followed a tutorial on how to write and read varbinary(max) data to and from a database. But when i try to read the data i get the error that the data would be truncated, but only when the varbinary(max) is greater then 8kB. I've used a system stored procedure (sp_tableoption) to set the table that holds the data to store data outside rows. To select the data i'm using a stored procedure: SELECT imageData , MIMEType FROM Pictures WHERE (imageTitle = @imageTitle) And then using an .aspx page to Response.Write the data:Using conn As New sql.SqlConnection conn.ConnectionString = ConfigurationManager.ConnectionStrings("myConnectionString").ToString Dim getLogoCommand As New sql.SqlCommand getLogoCommand.CommandType = Data.CommandType.StoredProcedure getLogoCommand.CommandText = "GetPicture" getLogoCommand.Connection = conn Dim imageTitleParameter As New sql.SqlParameter("@imageTitle", Data.SqlDbType.NVarChar, 200) imageTitleParameter.Value = Request("imageTitle") imageTitleParameter.Direction = Data.ParameterDirection.Input getLogoCommand.Parameters.Add(imageTitleParameter) conn.Open() Using logoReader As sql.SqlDataReader = getLogoCommand.ExecuteReader logoReader.Read() If logoReader.HasRows = True Then Response.Clear() Response.ContentType = logoReader("MIMEtype").ToString() Response.BinaryWrite(logoReader("imageData")) End If End Using conn.Close() End Using Can anyone please help me with this?!

Hello, everyone:
Does any one have an idea for hard drive configuration on SQL Server 2K? How to determine the RAID level for datafile and log file? Thanks
ZYT
I was wondering if anyone played around with changing the allocation unit size when formatting the hard drive the SQL server is running on. I would think that setting it higher to account for the larger size of the database files would help, but I'm not sure.
Anyone have any thoughts?
Hi guys,
I have a general question. Would SQL server have slower performance if you placed the ldf or mdf files on a dynamic drive setup or should it always be basic? I noticed that a server had 2 dynamic drives and the log files and mdf files are located on these drives. Usually I see all the drives as basic not dynamic. Does this even matter?
thanks
I want to perform backups to a network drive. I need to know if I can access the backup drive via UNC. I have not been able to get it to work and, for now, I would just like to know if what I am trying to do SHOULD work.

Thanks,Bob
I'm wondering what other people do in regards to running hard drive defragmentation programs on SQL Server 2005 servers (assume 64-bit and Windows 2003). From what I can tell the most common opinions are:
1. Don't defragment because it doesn't help and it can cause problems.
2. Use Diskeeper
3. Use the built-in Windows defragmenter
Other respected defragmented programs are PerfectDisk, O&O Defrag, JkDefrag, and Contig.
What is your hard drive defragmentation strategy?
Hi. Has anyone else had any problem with their SQL Server 2005 going nuts after installing the SP2 + the above hotfix?
We reboot the SQL Server and as soon as SQL receives a command of any sort, the SCSI RAID 5 hard drives light up and start trashing. Therefore every query and even Windows response time is painfully slow or fails to respond. When we look at the Activity Monitor and sp_who2 there is a process running a Select Into from Microsoft SQL Server Management Studio using the sa account from the last database name in our system. So we can't kill the process as it says "Cannot use KILL to kill your own process. Microsoft SQL Server, Error: 6104)".
The last Transact-SQL command from this process is:
create table #tmpDBCCinputbuffer ((Event Type) nvarchar(512),
[Parameters] int, [Event Info] nvarchar(512))
insert into #tmpDBCCinputbuffer exec ('DBCC INPUTBUFFER(56)')
select [Event Info] from #tmpDBCCinputbuffer
The only other issue I should mention is that we had to uninstall and reinstall SQL Server yesterday as SP2 only half installed. The SP2 install log indicated that SQL SP1 wasn't in a good state as we previously (3 months ago) performed an upgrade from Windows 2000 Server to Windows 2003 R2 Server.
Our other 3 Windows 2003 R2 Servers which were a clean install of both Windows and SQL are running fine.
I've been insisting that we do a new clean Windows and SQL install, but the other team members insist that it's been fine until we installed SQL Server SP2.
So can anyone provide and help or evidence to say who is right either way?
Thanks.
Dear group:I have removed my hard drive from my laptop (which is now toast) andhave managed to recover nearly all the data from it by installing thedrive into my desktop. I was hoping to reboot the dektop to see if Icould load the operating system on the laptop's hard drive so I coulddo a manual backup of the SQL database on it.

Hi,
Recently, I started to move more databases from SQL Server 2000 to 2005, well the Stored Procedures in 2005 is hard to handle.
First of all, I created the new SP in Object Explorer, the "New Stored Procedure" query just created a new name under the Stored Procedures folder, then I have to re-open it to put in TSQL code.
After I put in the code in the new SP, if I click "Save", the File
Manager comes out to let me to save in a physical location (C: or D: or Network place...). But after I close and open the new SP, the code I put in there is not really in the new SP.
I know that I have to "Execute" the SP in order to save the change. But the problem is I don't want to run the code at this step, the SP is to get a lot of data transactions, I'll setup a "Job" to do this.
So, the question is: Is this the way to create and save a new SP? Is there any other way to save the code changes in the SP WITHOUT "Execute" it?
Please give me any advise, article or links to read.
Thanks.
Hello.
One of our hard drives has crashed and as a result we have lost our master mdf/ldf & user db mdf/ldf files. It's not that a critical system by any means, but if the hard drive crashes and the master mdf/ldf files & user db mdf/ldf are lost, is there any way of restoring the system?
I'm thinking we probably need to re-install Enterprise Manager completely, and re-install the user db from a backup.
Any advice/suggestions would be much appreciated.
Thanks in advance,
Hi,
I've downloaded the sql server 2005 management studio express executable to my second hard drive, as there is no room on my main drive
However, when I try to install, the program shows me both drives, and shows that there is not enough room on my main drive, but it does not allow me to change the installation to my second drive.
I have previously installed the main sql express product to my second drive with visual studio. There's loads of room.
Can anyone give me a clue as to why this might be happening.
Thanks

I need to create a SQL server database and add some tables to it. Then access it with a C# application. The problem is that the new SQL server database and it's tables must reside on an external hard drive. How do I point SQL server to this external drive, so that I can create a database on this drive and then create tables and access data on it?
I'm trying to insert data into a table from two tables into a single table along with a hard coded value.
insert into TABLE1

Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

Can someone please tell me how to write data to a SQL table that is a Binary data type? I have a stored procedure on the SQL server that I am calling to insert data into a table. I build a parameter list and set the values. It worked just fine before I added a binary field to the SQL table. My problem is that I don't know how to set the Binay data type to pass it to the stored procedure. Here is part of the code:
GetCMD = Myconnection.CreateCommand
GetCMD.CommandType = CommandType.StoredProcedure
GetCMD.CommandText = "SCHEMANAME.InsertLineItem"
GetCMD.Parameters.Add("HEADER_ID", SqlDbType.VarChar, 150)
GetCMD.Parameters("HEADER_ID").Value = "some value"
GetCMD.Parameters.Add("@OPTIONS", SqlDbType.Binary)
GetCMD.Parameters("@OPTIONS").Value = HOW DO I SET THIS VALUE????
rowsaffected = GetCMD.ExecuteNonQuery()
I assume serialization but have not figured out how. Anyone's help is greatly appreciated!!
I am working on a program in VB 2005 in which i want to store and retrieve GPS coordinates. I am not sure which data type is the best to use to enter Latitude & Longitude numbers and maintain their proper integrity.
Like LAT ( N38 28.025' ) and LONG (W105 52.098' )
The numbers will be entered by the user and that format can be maintained, but how to re-enter & or insert them into the database using the same format is my real question.
I hope I have explained this right. The numbers in BOLD are what I need to maintain.
Thanks for any help in advance.

I'm using a bit-wise comparison to effectively store multiple values in one column. However once the number of values increases it starts to become too big for a int data type.you also cannot perform a bitwise & on two binary datatypes. Is there a better way to store the binary data rather than int or binary?
