CLR UDT Max Byte Size
Hello,
I need some help working with CLR UDTs. I have created two UDTs called trajectory and point. Each trajectory consists of a list of points. Each point consists of three members : lon( type double), lat( type double) and datetime.
I have written my own IBinarySerialize.Write method for the trajectory type which is the following:
Dim maxSize As Integer = 4000
Dim value As String = ""
Dim paddedvalue As String
Dim i As Integer
Dim pt As Point
For i = 0 To point_list.Count - 1
pt = point_list.Item(i)
If i = 0 Then
value = value & pt.X & "|" & pt.Y & "|" & pt.D
Else
value = value & ">" & pt.X & "|" & pt.Y & "|" & pt.D
End If
Next
paddedvalue = value.PadRight(maxSize, ControlChars.NullChar)
For i = 0 To paddedvalue.Length - 1 Step 1
w.Write(paddedvalue(i))
Next
If I try to store 225 points for a trajectory then the following error occurs:
System.Data.SqlTypes.SqlTypeException: The buffer is insufficient. Read or write operation failed.
Why is that happening? The limit size for a UDT is 8000bytes. Each point needs 24Bytes (2*SizeOf(double) + sizeOf(Datetime)).
Please help

Do Stored Procedures Have A Limit On Number Of Parameters Or Byte Size Passed In?
Hi,I'm using c# with a tableadapter to call stored procedures. I'm running into a problem where if I have over a certain byte size or number of parameters being passed into my stored proc I get an exception that reads: "Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized." If I remove one parameter, the problem goes away. Has anyone run into this before? Thanks,Mark

SQL Binary To C# Byte[]
I have a binary column with length 20 in SQL server table. I store dynamically C# byte[] value range from 0 to 19. So for example, If I store length of 16 and when I try to retrive it back into byte [] in C# it returns whole length 20. When I see in debug it has value from 0 to 15 which I want to use but from 16 to 19 is zero. How can I get just length value which I stored. I use DataRow to get whole row and from the row object I extract byte [] based on column name. Thank you in advance....

DATEADD With 8 Byte Int?
I have a bigint column called "MillisecondsSince1970" that I need to convert to a date - SSIS is erroring out when I use DATEADD with the 8 byte int (if I use 4 byte it works but the column is bigger than 4 byte). The error is really lame: [Derived Column [79]] Error: The "component "Derived Column" (79)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "Date" (100)" specifies failure on error. An error occurred on the specified object of the specified component. Anyone have a way around it... a VB.NET equivalent of DATEADD or something else I can do?

Doube Byte Characters
I want to store some double byte characters in a table. Originally I planed to change all data type of fields which will store double bytes from VARCHAR() to NVARCHAR(). But i just found out we have no problem to pull and store foreign content(double byte characters) in fields with VARCHAR type( the content is showing correct after stored in database) my question is : if VARCHAR can handle double byte character, what's the point of using NVARCHAR to store unicode character? any advice is appreciated.

Hi, Just wondering if anyone knows if you can create a certificate from a byte[]. For example, you can create an assembly using CREATE ASSEMBLY FROM 0x...; specifying the hex representation of it - can you do the same with a certificate?

Problem is one of the files stands a good chance of being 0 k. As of I now i call one stored proc that then calls one proc for each file. If i try to run it anyhting after the zero byte file fails to import. If i remark it out everything else imports. I check for file.exists on the vb.net and the file passes the test. Any way to handle the 0 byte on the proc side

DTS Package - How To Prevent A 0 Byte File?

DTS: Handling Zero Byte Input Files
Good Day, I have a situation where I need to be able to gracefully handle zero byte text files to be processed by DTS (using ActiveX Script transformations). I have a job set up in SQL Server that executes several DTS packages, then executes a Transact SQL script to process the data imported by DTS. This all works fine, but there are instances where some of files have no data to be imported. This causes the entire job to fail -- I don't want to alter the job to continue on an error because there is a legimate potential for errors. I do, however, want to be to have the job continue if one of the DTS packages has no data to process. Is there a way (DTS object method, property) to check for the absence of data before the DTS package errors out? Any ideas would be greatly appreciated. Regards, Robin Sarac

Derived Column Can't Add 8-byte Integers
I'm having trouble adding a 4-byte integer with an 8-byte integer. Here's what I'm doing: Column Name: BIG_ID Derived Column: < add as new column > Expression: (DT_I8)[ID] + 840230000538058 Data Type: eight-byte signed integer {DT_I8] The error I get: The literal 840230000538058 is too large to fit into type DT_I4. The magnitude of the literal overflows the type. Then I try the expression: (DT_I8)[ID] + (DT_I8)840230000538058 and [ID] + 840230000538058 and get the same error. What am I doing wrong? Is it possible to add 2 8-byte integers in regular expression? Why does it still think the literal is DT_I4? Thanks, Michael

Help: 900 Byte Limit On Stored Procedure Parameter?
Hi,I have a .NET application that I want to save the Config.EXE contentsto my SQL database for remote review/testing. This config file is3700+ bytes long. I created a field in one of my tables with a VARCHAR4800 and then created a stored procedure that receives a parameter(also VARCHAR(4800).However it fails to write anything if the length of the value that Ipass is anything greater than 900. If I pass exactly 900 characters orless - the data is written to the field. If I pass 901 characters Iget nothing.I'm suspicious since it is exactly 900. I seriously doubt it's somelimitation of MS-SQL so I need a nudge in the right direction.Thanks

DTS - Zerp Byte File Import And DontExecuteTask
Hi, I'm a bit new to DTS but the problem I have encountered relates to importing a text file. On occasion the file is zero bytes which causes an error in DTS. I have added some VBScript to the workflow to check the filesize. If size > 0 then I set Main = DTSStepScriptResult_ExecuteTask otherwise Main = DTSStepScriptResult_DontExecuteTask. This all works fine except that when the file is 0 the dependent process that is waiting for completion/success does not run, presumably because the task was not run (as reqd). I have tried setting the status rather the DontExecuteTask but then the task runs anyway creating the error. Anyonw know how to get this to work or how to get around the problem? regards Ken

Trying To Map To Tinyint - Single Byte Unsigned Int Not Working

When I have both the fiscal year name and the fiscal week of year, the package fails on the lookup step. In a data conversion, I convert the fiscal week of year to a single byte unsigned integer. (In the Date table, the fiscal week of year is a tinyint.) I'm not sure what I'm doing wrong?

How To: Store And Retrieve Images In A Database As A Byte Array.
I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field. I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?

I then add a flat file destination with code set 37 (ebcdic us / canda) with the corresponding columns using fixed width. When i place a dataviewer on the line between the two the output looks as I expect ("0x12 0x34 0x56 0x7F", "ABCD", "B123"). However, when it gets to the flat file destination it errors out with the following: Code Block [Flat File Destination [54]] Error: Data conversion failed. The data conversion for column "myByteStream" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.". If i increase the size of the byte stream (say, to 50) the error goes away but I am left with the string "1234567F" instead of the appropriate hex values. Any clues on how to go about this? I obviously don't care if it gets transferred to "readable" text as this is supposed to be a binary stream, thus the no match in target page seems superfulous but is probably what is causing the problems. NOTE: this is relating to the following thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2300539&SiteID=1) in that I am trying to determine why these people are not seeing the "UseBinaryFormat" when importing an EBCDIC file (i see this fine when i use an ftp'd file, but it auto converts to ascii) with comp-3 values. I also see the "UseBinaryFormat" when I am importing a regular EBCDIC file which I create that has no import errors with zoned decimals.

Sql 2005 Install Error. MODIFY FILE Failed. Specified Size Is Less Than Current Size.
I installed sql 2005 a while back. Then I recently found out my file system was fat32 (I don't understand why the hardware people did this...) and I had to convert to NTFS. Naturally the sql service no longer worked so I uninstalled inorder to reinstall now I can't reinstall it I keep getting this message native_error=5039, msg=[Microsoft][SQL Native Client][SQL Server]MODIFY FILE failed. Specified size is less than current size. I'll try to post the full log in a new post.

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

SPROC Problem - String[1]: The Size Property Has An Invalid Size Of 0.
Hi folks,Can anyone enlighten me here? I'm trying to use a SPROC which, when supplied with an int, looks up the table and returns certain columns from it. I'm using a SqlCommand, here's my codebehind: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ SqlCommand dataSource = new SqlCommand("retrieveData", new SqlConnection(dbConnString)); dataSource .CommandType = CommandType.StoredProcedure; dataSource .Parameters.AddWithValue("id", poid); dataSource .Parameters.AddWithValue("title", title).Direction = ParameterDirection.Output; dataSource .Parameters.AddWithValue("creator", creator).Direction = ParameterDirection.Output; dataSource .Parameters.AddWithValue("assignee", assignee).Direction = ParameterDirection.Output; etc, etc... And the SPROC:------------------------------------------------------------------------------------------------------------------set ANSI_NULLS ONset QUOTED_IDENTIFIER ONGOALTER PROCEDURE [dbo].[retrieveData] @id int, @title varchar(50) OUTPUT, @creator varchar(50) OUTPUT, @assignee varchar(50) OUTPUT, @contact varchar(50) OUTPUT, @deliveryCost numeric(18,2) OUTPUT, @totalCost numeric(18,2) OUTPUT, @status tinyint OUTPUT, @project smallint OUTPUT, @supplier smallint OUTPUT, @creationDateTime datetime OUTPUT, @amendedDateTime datetime OUTPUT, @locked bit OUTPUT AS /**SET NOCOUNT ON; **/ SELECT [title] AS [@title], [datetime] AS [@creationDateTime], [creator] AS [@creator], [assignee] as [@assignee], [supplier] as [@supplier], [contact] AS [@contact], [delivery_cost] AS [@deliveryCost], [total_cost] AS [@totalCost], [amended_timestamp] AS [@amendedDateTime], [locked] AS [@locked] FROM purchase_orders WHERE [id] = @id; ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ The id being passed in is definately not null, and is set to a value of an item I know exists. The resulting error is: Exception Details: System.InvalidOperationException: String[1]: the Size property has an invalid size of 0.Line 63: retrievePODetails.Connection.Open();Line 64: retrievePODetails.ExecuteNonQuery();[InvalidOperationException: String[1]: the Size property has an invalid size of 0.] System.Data.SqlClient.SqlParameter.Validate(Int32 index) +717091... ... Can anyone see anything I'm missing? Thanks,Ally

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 128KB. So far I expect to set 64KB stripe size and have a couple partitions: - 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. Victor

Encrypted Data Size By Original Size, Algorithm ?
I want to know encrypted data's size for designing database field size. For example, cardnumber varchar(20) Encrypted by Triple_DES and PassPhrase, How match size does need to encrypted data store field. I think the size does not depend to PassPhrase char length. Regards, Yoshihiro Kawabata

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. (Example:) 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. Regards,

Size Of Backup Is Less Than Size Of Database
any of you know why the size of the database dump (prod_dump.dat) is less than the size of the database (prod) prod size is 3000 MB ( in EM and sp_helpdb) used is 1092 MB ( datasize - data available ) however e:dumpproddump.dat is only 1.5 GB and the backup task completes with no errors. why the discrepancy??

DB Size Not The Actual Physical Size
Hi, An MSSQL DB running SAP indicates a smaller DB size (MMC & SAP) than the actual physical size. The difference is about 8 GB. A lot of records were deleted before this. Did they remain in the DB as NULL values or something ? Does anyone know what the reason for this could be ? And how to clean this up ? Thanks in advance, Paul

Table Size And Database Size
Hi, i use this script that show me the size of each table and do the sum of all the table size. SELECT X.[name], REPLACE(CONVERT(varchar, CONVERT(money, X.[rows]), 1), '.00', '') AS [rows], REPLACE(CONVERT(varchar, CONVERT(money, X.[reserved]), 1), '.00', '') AS [reserved], REPLACE(CONVERT(varchar, CONVERT(money, X.[data]), 1), '.00', '') AS [data], REPLACE(CONVERT(varchar, CONVERT(money, X.[index_size]), 1), '.00', '') AS [index_size], REPLACE(CONVERT(varchar, CONVERT(money, X.[unused]), 1), '.00', '') AS [unused] FROM (SELECT CAST(object_name(id) AS varchar(50)) AS [name], SUM(CASE WHEN indid < 2 THEN CONVERT(bigint, [rows]) END) AS [rows], SUM(CONVERT(bigint, reserved)) * 8 AS reserved, SUM(CONVERT(bigint, dpages)) * 8 AS data, SUM(CONVERT(bigint, used) - CONVERT(bigint, dpages)) * 8 AS index_size, SUM(CONVERT(bigint, reserved) - CONVERT(bigint, used)) * 8 AS unused FROM sysindexes WITH (NOLOCK) WHERE sysindexes.indid IN (0, 1, 255) AND sysindexes.id > 100 AND object_name(sysindexes.id) <> 'dtproperties' GROUP BY sysindexes.id WITH ROLLUP) AS X ORDER BY X.[name] the problem is that the sum of all tables is not the same size when i make a full database backup. example of this is when i run this query against my database i see a sum of 111,899 KB that they are 111MB,but when i do full backup to that database the size of this full backup is 1.5GB,why is that and where this size come from?

Unable To Cast Object Of Type 'System.DBNull' To Type 'System.Byte[]'.
Hi, I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ? Thanks a lot in advance.
