Size To Specify For Varchar(Max) Field

After reading Dan Guzman's blog entry (http://weblogs.sqlteam.com/dang/archive/2008/02/21/Dont-Bloat-Proc-Cache-with-Parameters.aspx) I started modifying some of my code to try it out and ran into a stumbling block. What size would you specific for a varchar(MAX) field?
Since a varchar max field can hold up to 2 billion chracters I really don't think I need to specify 2 billion as the size. Anyone have any ideas?

VarChar Size Concerns

Is a near-empty VarChar 8000 any less space-efficient than a near-empty VarChar 100?

We're creating note fields that are usually near-empty, but could grow larger on occasion. We'd like to know for sure whether the only difference between a small and large VarChar is simply the maximum length allowed.

SQL Server 2000 Standard .. DB Size Limit

Hi all.

On the MS website (at this URL: http://www.microsoft.com/sql/evaluation/overview/default.asp) it says that the Standard edition of SQL Server 2000 has a database size limit of 1,048,516 terabytes.

Talking to a friend, he tells me this is not true, and that it has a database size limit of 12gb.

Is Microsofts site incorrect, or is my friend lost?

Cheers! :-)

7.0 Standard Desktop Database Size Limitation?

I am running 7.0 standard desktop on Workstation 4.0 and have run into a database size limitation of 10GB. I have all the newest
patches and have found no documentation that refers to a 10GB limitation. A September copy of VBA developer says that this edition
has a limitation of 4GB while the guides say that the Small Business Server edition would have a 10GB limitation. All other forms
of documentation say that there should be the standard mega-terabyte limit. I'm completely confused by this [lack of] documentation.
Any help???

Help! Limitations On Varchar Size And Not Being Able To Use TEXT In Stored Procedure

I am stuck! and need help!

I have a problem I can't seem to find the solution with this aweful limitations on VARCHAR fields of 255.

Within a stored procedure called Store_Check, I need to dynamically build a string (@string) using VARCHAR(255) since the text datatype can't be used in a stored procedure.

So,this string is built according to whether the Store ID is NOT NULL. So if the StoreID is not null, I start building this string 'Exec Update_Store_Address @StoreID1, @address2'. There are 20 StoreID's passed into Store_Check. IF all 20 StoreID's are not NULL, the executed String greatly exceeds 255 because the string winds up looking like this

'Exec Update_Store_Address @StoreID1, @address1 Exec Update_Store_Address @StoreID2, @address2 Exec Update_Store_Address @StoreID3, @address3 Exec Update_Store_Address @StoreID4, @address4 Exec Update_Store_Address @StoreID5, @address5 Exec Update_Store_Address @StoreID6, @address6 etc. etc.'

I am not executing this string within the StoredCheck procedure. It needs to be passed as ONE string to a VB program and it gets executed by the VB program. Even if I create 4 local variables and concatenate them, it stops at the 255th character.

Also, a local varialbe of type TEXT cannot be declared within stored procedure.

What can I do? I am stuck!

Compare Standard Evalulation To Standard License Version

Hi All,

Good Evening.

I need a comparision between Evaluation copy and Standard license version of SQL Server 2005 /SSIS.

I'm assigned a task to evaluate SSIS and migrate a project to SSIS.

I have downloaded SSIS evaluation version and started working on that.

Now i'm being posed questions for the complete functionality of the tool...

- Whether it has a Bulk load trasformation ?

- Whether the evaluation version contain all the features of a standard license version ?

I need to submit a consolidated report for SSIS in comparision to the current ETL tool features.

Can you please let me is there any considerable features not given with a evaluation copy ?

Thanks in advance,

Problems Moving Data Over 8000k In DB2 Varchar Column Into SQL Server Varchar(max) Using SSIS

I have looked far and wide and have not found anything that works to allow me to resolve this issue.

I am moving data from DB2 using the MS OLEDB Provider for DB2. The OLEDB source sees the column of data as DT_TEXT. I setup a destination to SQL Server 2005 and everything looks good until I try and run the package.

I get the error:
[OLE DB Source [277]] Error: An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft DB2 OLE DB Provider" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".

[OLE DB Source [277]] Error: Failed to retrieve long data for column "LIST_DATA_RCVD".

[OLE DB Source [277]] Error: There was an error with output column "LIST_DATA_RCVD" (324) on output "OLE DB Source Output" (287). The column status returned was: "DBSTATUS_UNAVAILABLE".

[OLE DB Source [277]] Error: The "output column "LIST_DATA_RCVD" (324)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "LIST_DATA_RCVD" (324)" specifies failure on error. An error occurred on the specified object of the specified component.

[DTS.Pipeline] Error: The PrimeOutput method on component "OLE DB Source" (277) returned error code 0xC0209029. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.

Any suggestions on how I can get the large string data in the varchar column in DB2 into the varchar(max) column in SQL Server 2005?

The Data Types Varchar And Varchar Are Incompatible In The Modulo Operator

I am trying to create a store procedure inside of SQL Management Studio console and I kept getting errors. Here's my store procedure.

Code Block
CREATE PROCEDURE [dbo].[sqlOutlookSearch]

@OLIssueID int = NULL,
@searchString varchar(1000) = NULL
-- SET NOCOUNT ON added to prevent extra result sets from

SELECT * FROM [Outlook]
WHERE [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''

And the error I kept getting is:

Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 18

The data types varchar and varchar are incompatible in the modulo operator.

Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 21

SSIS - Importing Varchar From Access Into SQL2005 As Varchar

For the life of me I cannot figure out why SSIS will not convert varchar data. instead of using the table to table method, I wrote a SQL query so that I could transform the datatype ntext to varchar 512 understanding that natively MS is going towards all Unicode applications.

The source fields from Access are int, int, int and varchar(512). The same is true of the destination within SQL Server 2005. the field 'Answer' is the varchar field in question....

I get the following error

Validating (Error)


Error 0xc02020f6: Data Flow Task: Column "Answer" cannot convert between unicode and non-unicode string data types.
(SQL Server Import and Export Wizard)

Error 0xc004706b: Data Flow Task: "component "Destination - Query" (28)" failed validation and returned validation status "VS_ISBROKEN".
(SQL Server Import and Export Wizard)

Error 0xc004700c: Data Flow Task: One or more component failed validation.
(SQL Server Import and Export Wizard)

Error 0xc0024107: Data Flow Task: There were errors during task validation.
(SQL Server Import and Export Wizard)

DTS used to be a very strong tool but a simple import such as this is causing me extreme grief and wondering of SQL2005 is ready for primetime. FYI SP1 is installed. I am running this from a workstation and not on the server if that makes a difference...

Any help would be appreciated.

Datatype Question Varchar(max), Varchar(250), Or Char(250)

I have a table that contains a lot of demographic information. The data is usually small (<20 chars) but ocassionally needs to handle large values (250 chars). Right now its set up for varchar(max) and I don't think I want to do this.

How does varchar(max) store info differently from varchar(250)? Either way doesn't it have to hold the container information? So the word "Crackers" have 8 characters to it and information sayings its 8 characters long in both cases. This meaning its taking up same amount of space?

Also my concern will be running queries off of it, does a varchar(max) choke up queries because the fields cannot be properly analyzed? Is varchar(250) any better?

Should I just go with char(250) and watch my db size explode?

Usually the data that is 250 characters contain a lot of blank space that is removed using a SPROC so its not usually 250 characters for long.

Any insight to this would be appreciated.

Error - Output Param - SP - Size Property Has An Invalid Size Of 0

Using C#, SQL Server 2005, ASP.NET 2, in a web app, I've tried removing the size from parameters of type NCHAR, NVARCHAR, and VARCHAR.  I'd rather just send a string and let the size of the parameter in the SP truncate any extra chars if need be. I began getting the error below, and eventually realized it happened only with output parameters, as in the code snippet below.String[3]: the Size property has an invalid size of 0.   par = new SqlParameter("@BusinessEntity", SqlDbType.NVarChar);  par.Direction = ParameterDirection.Output;  cmd.Parameters.Add(par);  cmd.ExecuteNonQuery();What's the logic behind this? Is there any way around it other than either finding out what the size should be, or assigning a size larger than would ever be needed? ThanksMike Thomas

Optimal RAID Stripe Size And OS Cluster Size?

I need to setup HP NetServer, which will run mainly SQL 7
on Win2K (it'll also run an aplication server, which would
connect to SQL but it wouldn't take too much resources).
The server has 3 ULTRA3 SCSI 18GB, 10.000rpm hard drives
connected to HP NetRAID-1M Controller. To provide some
redundancy I basicaly have just one choice: RAID5.

But what would be the optimal RAID stripe size and Windows
cluster size to provide the best performance for SQL
Server? Controller support stripe sizes from 2KB up to

So far I expect to set 64KB stripe size and have a couple

- one, with 4KB cluster size, for OS, SQL binaries, logs
and all other program and auxiliary fiiles,
- another one, with 64KB cluster size, for SQL databases
and transaction logs.

Is it the best possible disk configuration considering
available hardware?

Thank you for any comments/suggestions.

Best Practice For Data Size/Log Size Ratio

Just wanted to know what is a general rule of thumb when determining log file space against a database's data file.We allow our data file for our database to grow 10%, unlimited. We do not allow our log file to autogrow due to a specific and poorly written process (which we are in a three month process of remove) that can balloon the log file size.Should it be 10% of the Data file, i.e. if the Date file size is 800MB the log file should be 8MB?I realize there are a myraid of factors that go against file size but a general starting point would be nice.ThanksJeff--Message posted via http://www.sqlmonster.com

Estimating Data Size And Log Size In A Database

Question 1:
I wonder if anyone could help me on estimating the acutal data size and its log size for MS-SQL Server version 7. I know that on-line book specifies the procedure of the data size but I have some data items with attribute of data type as "Text".
In order to include the data type "Text" how many bytes of overhead and fill factor to be considered for data size calculations?

Question 2:
Also, I want to know that if anyone can help me with log size calculation for a table. It's just not good enough if the on-line book says to take from 25 to 50 % or something....it is too vague and I can not take the answer.

Here are the example of the table and if anyone can include the answers to the questions above. It will be great.

Can anyone help me to figure out the data and log size respectively based on the conditions below:
1. Table Name: A_TBL
2. Table Format:
Item Data Type Length
EmployeeNumber Char 20
EmployeeName Char 50
EmployeeURL TEXT 16 -----pointing---> 256
EmployeeMemo TEXT 16 -----pointing--->1000
EmployeeTitleNo Int 4

3. DB(Table) access frequency per transaction:
Insert = 1 time/transaction
Update= 2 times/tranaction
Select = 6 times/tranaction

4. Transaction occurred: 10 times, therefore; 10 INSERT, 20 UPDATE, 60 SELECT statements are issued.
(I guess 60 SELECT statements are not subject to be in the log so forget the SELECT statement)

5. Fill Factor 100 for all the data type.

6. Non-Clustered index is set for the above.

I really want to know about it, please help me on this.

Difference VarChar(50) And VarChar(500)


I was doing some research on how SQL stores data on disk.
MSDN states that when storring a varchar, only the length of the data itself is used plus two bytes.
So, if you store "car" in a VarChar(50) it will take 5 bytes.
But when you store "car" in a VarChar(500) it will also take 5 bytes.

What is the reason users should define the parameter lenght?
Can you use VarChar(8000) whole the time, without any drawback?
