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?
Imports System.Drawing Imports System.IO
Public Sub InsertImage(ByVal pFilename As String)
Try
Dim lImage As Image Dim lBA() As Byte Dim lSQL As String Dim lQuery As Alcon.SQLServer.Database.clsQuery Dim lParameters As New Alcon.SQLServer.Database.clsParameters
lImage = Image.FromFile(pFilename)
ConvertImageToByteArray(lImage, lBA)

Hi, I have a problem importing data from SQL Server 2000 'text' columns to SQL Server 2005 nvarchar(max) columns. I get the following error when encountering a transfer of any column that matches the above. The error is copied below,
Any help on this greatly appreciated...

I have a stored procedure that has a paramter that accepts a string of values. At the user interface, I use a StringBuilder to concatenate the values (2,4,34,35,etc.) I would send these value to the stored procedure. The problem is that the stored procedure doesn't allow it to be query with the parameter because the Fieldname, "Officer_UID" is an integer data type, which can't be query against parameter string type. What would I need to do to convert it to an Integer array? @OfficerIDs as varchar(200) Select Officer_UID From Officers Where Officer_UID in (@OfficerIDs) Thanks
I had a situation that required me to set up SQL Server to do full text search against both English content and Chinese content. I am not sure if it's achievable in SQL server environment. Any help is appreciated.
Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?

I would like to write a fun or stored procedure to do some operation. It require me to know that what category is currently belong to certain people(people_table: category_table1 to Many)However, when i use the select statement in stored proc, it return a set of result, not a scalar , therefore, i cannot use the variable to hold it. In addition, there are no array in SQL server.Question:1. Is there any way to hold the collection of result(like array)?2. Also, how to determine to use fun or stored procedure?(Since a integer is need to return by them)Thx
My main sql server lost the system board due to overheating. I need to get the (external enclosure scsi attached)array up and running as it has production data as well as SQL backups stored there. My most recent/valid backups are located with the production data. It is possible to connect this array to different server? This is a HP DL380 and all of my other servers are Dell 2900's.
I am looking for information/suggestions in regards to portioning data across a large SAN. The database is several TB in size, and we are looking to partition the data on a date so that the current data is always the fastest available and history can be set as read only but still be available.
If the server has 8 drive letters how can I ensure that the 4 data drives are stripped across the most physical drives for the most through-put??
Are there any specific questions I need to ask the server technicians?
I've been doing this in Access, but cannot find the answer to how to do it with SQL Server. From a web form, a user can select a number of different dates. The selected dates are held as text (not DateTime) in an ArrayList. Clicking the Submit button writes the contents of the form to a database table. This works for Access: insSQL &= "VALUES (@typEvent, @starts, @ends, @starts, @ends, @attend, @title, @room, @department, @contact, @address, @telephone, @email, @telefax, " For i = 0 to datesArray.Count - 1 insSql &= datesArray.Item(i) Next i insSQL &= "VALUES (@typEvent, @starts, @ends, @starts, @ends, @attend, @title, @room, @department, @contact, @address, @telephone, @email, @telefax, " For i = 0 to datesArray.Count - 1 insSql &= "#" & datesArray.Item(i) & "#, " Next i It doesn't work for SQL Server, and when trying to insert the value "01/29/2007" I get the error message: "The name '#1' is not permitted in this context. Only constants, expressions, or variables allowed here. Column names are not permitted." I have also tried the line: For i = 0 to datesArray.Count - 1 insSql &= satesArray.Item(i) Next i and get: "Incorrect syntax near the keyword 'VALUES'." I'm not sure where to find the information to correct my error. Any help would be appreciated. Tinker
I was migrating from Oracle to SQL Server 2005 using SSMA (SQL Server Migration Assistant) but i`ve found an issue, i can´t find how to fix it. In my stored procedure in PL/SQL exists this lines:
TYPE T_ARRAY_COL IS VARRAY (1000 ) OF VARCHAR2 (50); A_COLUMNS T_ARRAY_COL := T_ARRAY_COL();
Somebody know how can i simulate this data type ARRAY. I was reading http://msdn.microsoft.com/msdnmag/issues/04/02/TSQLinYukon/ but some things are not clear for me.... please help me, give me one hand.
Hi people,I have a little problem with this!There are some variables in C# code: int personID = 10; string personName = "Tom";
System.IO.BinaryReader reader = new System.IO.BinaryReader(FileUploadPersonPhoto.PostedFile.InputStream);
byte[] personPhoto = reader.ReadBytes(FileUploadPersonPhoto.PostedFile.ContentLength); After that, there is a SQL query: string query = "INSERT INTO PersonTable (PersonID, PersonName, PersonPhoto) VALUES ("
+ personID + ", '" + personName + "', " + personPhoto + ")"; In Debug mode, value of the query is "INSERT INTO PersonTable (PersonID, PersonName, PersonPhoto) VALUES (10, 'Tom', System.Byte[])" and it does not work! Is there any prefix or something else that I should put and make it work?Thank you in advance!P.S. Do not want to use sql parameters at this piont!
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.
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
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?
Can we regenerate a .rdl file based on the byte[] stream created by Render method?
user sends the report name with parameters to application server and it is application server sends the request to Reporting Server and get the report back (Render method). But how to pass the returned byte[] stream to user and show her/him a report?
Is there any array data type in SQL Server 7.0. I am using VB 6.0 with ADO 2.1. I am populating a MSFlexGrid with values that I pass to SQL Server one at a time and insert into the database. What I would like to do is pass the entire contents of the Grid at once to a stored procedure and let SQL do the processing so my routine is not going back and forth to the client. I did not find any documentation on any array data types in SQL. What is my best approach to this problem? Thanks, Dan Collins
I have followed many examples found on this site, but still get an invalid cast execption when I attempt to run code below. the exception is thrown when I try to convert the sql image to a byte[] in the download section of the code.
//upload file private void Button1_Click(object sender, System.EventArgs e) { //Get the filename of the pdf file to be uploaded. string strFilename = File1.PostedFile.FileName.Substring(File1.PostedFile.FileName.LastIndexOf("\") +1);
//Get the file type string strFileType = File1.PostedFile.ContentType;
//Get the file size int intImageSize = File1.PostedFile.ContentLength;
// Reads the Image Stream ImageStream = File1.PostedFile.InputStream;
byte[] ImageContent = new byte[intImageSize + 1]; int intStatus = 0; intStatus = ImageStream.Read(ImageContent, 0, intImageSize);
i have trouble while insert/update a field which contains double-byte characters (Chinese Traditional).
NO PROBLEM if i m using Enterprise Manager to view/edit the data. They are retrieved properly in the following: (1) Enterprise Manager (2) Query Analyzer (3) Visual Basic (4) Command prompt isql
EACH of the Chinese words are become a qustion mark '?' if the UPDATE SQL or stored procedure executed in the following: (2) Query Analyzer (3) Visual Basic
WHILE (4) Command prompt isql does not have the problem for the same UPDATE SQL and stored procedure.
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.
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? This means that you don't need to save the file to disk before loading it into the database.
Hi, I m using sql 2005 as a back end in my application... I am useing Store procedure..for my data in grid..
ALTER PROCEDURE [dbo].[ProductZoneSearct] ( @Productid char(8),@Proname char(8),@radius int,@mode varchar(5) = 'M',@Zone nvarchar(1000),) ASSET NOCOUNT ON;Create Table #Product (ProductID int, TimeEntered datetime, DateAvailable datetime, Productname varchar(80), City varchar(50), State char(4),Miles decimal, Payment varchar(40),UserID int, Phone varchar(15)) Insert #Product Select ProductID , TimeEntered, DateAvailable, Productname ,City,State,miles,Payment ,Miles, UserID, Daily, PhoneFrom [tblproduct] Where city IN (@Zone) Select ProductID TimeEntered, DateAvailable, Productname City,State,miles,Payment ,Miles, U.Phone As phoneNumber, Company, , L.Phone As cmpPhone From #Product As L Left Join (Select UserID, Company, Phone, From [User]) As U On U.UserID = L.UserID Order By DateAvailable
if i pass value in "where city in (@Zone)" and @Zone ='CA','AD','MH' then it can not get any result..but if write where city in ('CA','AD','MH') then it give me perfact result.. I tried to below syntax also but in no any user Where city IN ('+@Zone+') In short if i pass value through varibale (@Zone) then i cant get result...but if i put direct value in query then only getting result..can anybody tell me what is problem ? Please Hel[p me !!! Thank you !!!
I'm getting a file that essentially has a parameter array: a specific like would have three known values, and then x number of groups of four parts;
The question is how to handle logical groups of parameters; i though maybe by using a modulous on their itemnumber ...
So I can easily use DelimitedSplit8K to definitively find the first thee values, but how do I dynamically get X number of groups of four; eventually i need the first three fields combined with each quadgroup.
So a rough example of the desired output is this:
this: '03,0000001,USD,010,81257946,,,015,121809761,,'is split into rows with the first three columns included in each row: 030000001USD01081257946NULLNULL 030000001USD015121809761NULLNULL
Here's a setup i've put together:
IF OBJECT_ID('tempdb.[dbo].[#AccountIdentifier]') IS NOT NULL DROP TABLE [dbo].[#AccountIdentifier] GO CREATE TABLE [dbo].[#AccountIdentifier] ( [AccountIdentifierID] INT IDENTITY(1,1) NOT NULL, [DateReceived] DATETIME NULL DEFAULT getdate(), [RecordCode] VARCHAR(3) NULL,
Hello, I'm having users upload documents to my db and storing them as an Image datatype, I can do that without an issue. I'm also able to find that record and return it as a byte(). Now, what's the best practice/scheme to return it to the browser, even FF, and have it prompt the user with the Open or Download thing Dialogue we all know and love.
I've created a DTS package -- that uses a query to export to a .txt file. My question is -- if the results of this query are zero (no results returned within the package ) -- how can I tell the package not to export a zero byte file. Any thoughts on that? Any help you could give would be greatly appreciated. Thanks!
i'm trying to read an image file from a database(ms-sql, .mdf) with type image. Anyone have any ideas on how to do this? I have a table adapter created but could not assign it to my byte[] variable. Thanks in advance.
