Hi,
Can any one help me to retrieve an image data from a table.
I wanted to show the images on my web page using ASP.
I am trying with pub_info table of pubs database, in this table logo is a image data type colum. I opened a record set in ASP page and I am not able to retrieve the image from the record set.
Any help is appreciated!

Ok, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.
using the following vb.net code:
'Dim sel2 As String
'Dim myCom As SqlCommand
'Dim conn As New SqlConnection
'Dim drr As SqlDataReader
'Dim image As System.Drawing.Image
'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "
'conn.ConnectionString = ("server=developer01;uid=sa;password=aims;database=DVPSOC;timeout=45")
'myCom = New SqlCommand(sel2, conn)
'conn.Open()
'drr = myCom.ExecuteReader()
'If drr.Read Then
' Me.ImageMap1.ImageUrl = drr.Item("attach")
'End If
'conn.Close()
Am getting an exeption on the following line Me.ImageMap1.ImageUrl = drr.Item("attach")
saying: Conversion from type 'Byte()' to type 'String' is not valid.
knowing that i tried converting using ToString but it's not getting any output then.
thanks for your help.

Hi, I'm stuck trying to figure out how to call an image from the database by certain ids. I want to get it like this: page.aspx?pictureid=#&userid=#
here's the show.aspx:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim PictureID As Integer = Convert.ToInt32(Request.QueryString("ppID"))Dim MemberID As Integer = Convert.ToInt32(Request.QueryString("mID"))
'Connect to the database and bring back the image contents & MIME type for the specified pictureUsing myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("objConn").ConnectionString)
Const SQL As String = "SELECT [ppMIMEType], [ppImageData] FROM [tblPP] WHERE ([ppID] = @ppID) & ("[mID] = @mID)"Dim myCommand As New SqlCommand(SQL, myConnection)
myCommand.Parameters.AddWithValue("@ppID", PictureID)
myCommand.Parameters.AddWithValue("@mID", MemberID)
myConnection.Open()Dim myReader As SqlDataReader = myCommand.ExecuteReader
If myReader.Read ThenResponse.ContentType = myReader("ppMIMEType").ToString()
Response.BinaryWrite(myReader("ppImageData"))
End If
myReader.Close()
myConnection.Close()
End Using
End Sub
here's the formview to display image with datasource:
<asp:FormView ID="PictureUI" runat="server" DataKeyNames="ppID,mID" DataSourceID="PicturesDataSource" AllowPaging="False" EmptyDataText="There are currently no pictures uploaded" HorizontalAlign="Center" CellPadding="0">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("ppID", "~/Show.aspx?ppID=" & 1 &"mID=" & 1 &"") %>' />
</ItemTemplate>
</asp:FormView>
<asp:SqlDataSource ID="PicturesDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:Connect %>"
SelectCommand="SELECT [ppID], [ppDateTime], [mID] FROM [tblPP] ORDER BY [ppDateTime]">
</asp:SqlDataSource>
How would I do if I want to make a query that returns an image, which in turn should be displayed on a webpage?
View 2 Replies View RelatedHello,
I have not seen a response to this specific question so here goes. I had working code for loading an image into my smart device SQLCE db and for retrieving images. But after upgrading my application to SQLCE 2.0 I am unable to use my retrieve code. This is what was previously working,
Dim ImageBytes As Byte = rs.GetValue(rs.GetOrdinal("OLE"))
Dim ImageStream As New System.IO.MemoryStream(ImageBytes)
frmFlashcardActive.picboxBlobToPicBox.Image = New Bitmap(ImageStream)
Help!
This is what I successfully use to save the image to the database
Dim PictureInfo As New FileInfo("My DocumentsUSAFlag.bmp") 'OpenDialog.FileName
Dim PictureSize(PictureInfo.Length) As Byte
If PictureSize.GetValue(0) <= 69 Then
Dim fsPicture As New FileStream(PictureInfo.FullName, FileMode.Open)
Dim PictureReader As New BinaryReader(fsPicture)
PictureReader.Read(PictureSize, 0, PictureSize.Length)
'find the previous record and add the picture
rs.SetValue(rs.GetOrdinal("OLE"), PictureSize) 'could be FlashcardAPic
rs.SetValue(rs.GetOrdinal("Picture"), "True")
rs.Update()
fsPicture.Close()
can anyone out there help me to solve this problem???

View 1 Replies View RelatedHi, everione,
I am having a big problem, trying to create datebase.
I have 3 tables: SUPERAVATAR, MASTERAVATAR, MEGAAVATAR.
- SuperAvatars are heroes in an online role playing gaming. They have an ID, ‘superavatarID’ which contain an UNIQUE NUMBER NOT NULL PRIMARY KEY to identify them.
A wisdom – ‘trickster’,’conjuror’,’magician’, etc..
A current owner… who is the user or player of the game and has that Super Avatar– we associate the link to USERID to know the person.
SuperAvatars can be fathers or mothers of Mega Avatars.
-MegaAvatars are the children of SuperAvatars…. They also have an ID UNIQUE NUMBER NOT NULL PRIMARY KEY to indentify them.
A magic power – it can be a ‘Leader’ or ‘Sheep’…
A ‘parent’ – parent is the number identifying to know to who Super Avatar belongs.
e.g.
SUPERAVAT WISD CURRENTOWNER FATHEROF MOTHEROF
1 Thick 3 1
2 Mentally Ch. 11 3
3 Smart 9 2
4 Genius 16 4
5 Thick 19
MEGAAVATARID MAGICPOWER PARENT
1 MAGICIAN 1
2 WIZARD 3
3 SORCERER 2
4 MAGICIAN 4
-We see that MEGAAVATAR 1 has a magic power as Magician and his father is ‘1’. ‘1’ identifies the SUPERAVATAR.
We see SUPERAVATARID…. who has the number ‘1’? the first in the row… who has wisdom – thick and he belongs to the USER with ID number 3.
-We see MEGAAVATARID… we choose the number 2…. His magic power is as WIZARD… and his father is the number 3.
We see SUPERAVATARID now… we look up the SuperavatarID 3…. We can see he has a wisdom – GENIUS… who belongs to the USERID 16 and he is father of MEGAAVATAR number 2.
The list can carry on and never stop.
I have this Problems:
We create in this example 3 tables: Users, SuperAvatar, MegaAvatar
SQL
CREATE TABLE users(userID NUMBER CONSTRAINT pk_user PRIMARY KEY,email VARCHAR2(50) NOT NULL UNIQUE,password VARCHAR2(15) NOT NULL UNIQUE,subscription CHAR(8) NOT NULL CHECK (subscription IN('ACTIVE' , 'INACTIVE' ) ) );
CREATE TABLE superavatar(superavatarID NUMBER CONSTRAINT pk_superavatar PRIMARY KEY, wisdom VARCHAR2(19) NOT NULL CHECK (wisdom IN ('THICK', 'MENTALLY CHALLENGED', 'AWAKE', 'SMART', 'GENIUS')), currentOwner NUMBER NOT NULL, fatherOf NUMBER,motherOf NUMBER);
CREATE TABLE megaavatar (megaavatarID NUMBER CONSTRAINT pk_megaavatar PRIMARY KEY, magicPower VARCHAR2(12) NOT NULL CHECK (magicPower IN('TRICKSTER','CONJUROR','MAGICIAN','WIZARD','SORCERER')), parent NUMBER);
Now, the 3 tables are created…..
What happen when we try to insert values to this table?
In this case we insert to User Table some examples:
INSERT INTO users VALUES('3','john@hotmail.com','great78','ACTIVE');
INSERT INTO users VALUES('9','chrisandsandra@gmail.com','chrisandra)','ACTIVE');
Now, we insert to SuperAvatar some examples;
INSERT INTO superavatar VALUES('1','THICK','3','1','');
INSERT INTO superavatar VALUES('3','SMART','9','3','');
|
|
‘9’ is the UserID that we already insert to the User table
What’s the problem?
We have to insert manually the data from USERID to CURRENTOWNER as we didn’t match or link CURRENTOWNER from SUPERAVATAR Table to USERID from USER Table with a SQL CODE.
What happen if we have thousands of USERS that they register to this game…? We will never know to how belongs that SUPERAVATAR but if someone do it manually can spend a year.
I am trying to fix this problem …. I add in SUPERAVATAR TABLE ‘CHECK’ in currentOwner..
SQL> CREATE TABLE superavatar
(superavatarID NUMBER CONSTRAINT pk_superavatar PRIMARY KEY, wisdom VARCHAR2(19) NOT NULL CHECK (wisdom IN ('THICK', 'MENTALLY CHALLENGED', 'AWAKE', 'SMART', 'GENIUS')),
currentOwner NUMBER NOT NULL CHECK (currentOwner IN(SELECT userID FROM users)),
fatherOf NUMBER,
motherOf NUMBER);

ERROR:
ORA-02251: subquery not allowed here
It doesn’t work.
Please HELP, I have exam tomorrow
thank you

Hi there, here is my current query:
sqlTemp = "SELECT id,code,description FROM tbl_content " &_
"WHERE EXISTS " &_
"(SELECT * FROM tbl_published_content " &_
"WHERE tbl_content.id = tbl_published_content.id ORDER BY tbl_published_content.nCorrectOrder)"
I don't get results sorted by tbl_published_content.nCorrectOrder, and have also no iea how to retrieve that values.
Please can any one tell me how can I have access to tbl_published_content.nCorrectOrder and get it sorted by this field?
So I can use objRS.("tbl_published_content.nCorrectOrder") or some alias?
thanks a million!
What would be the most efficient method of constructing a sql statement to retrieve certain record into (this gets tricky) rows of a table with 3 columns date.desc.
<table>
@foreach(var row in maytable){
<tr>
<td>@row.Most_Recent_Record1</td>
<td>@row.Most_Recent_Record2</</td>
<td>@row.Most_Recent_Record3</</td>
</tr>
}
</table>
I have 4 tables I am pulling data from. Table A and B can be joined and Table C and D can be joined via foreign keys but A and/or B can not be Joined to C and/or D via foreign Key.
My statement basically looks like this to start
SELECT s.HTENANT, s.HPROP, s.HUNIT, s.SHEADNAME3B, s.DTOT7I
FROM H8summ S join tenant t on s.htenant = t.hmyperson
And returns this :
29226 128 20577 Almukhtar, Khadijah M 4242.00
26574 128 17980 Archie, Mary 20218.00
The last number is the key it is the income.
In another table we have an income limit table setup that would have the low, medium and high settings for the range.
For instance it may have 11400 as the elimit attribute and say 22000 as the vlimit attribute.
Then in the fourth table we the description that can be linked back to the income limit table via the hinclimit attribute. In this case the desc attribute would be ELI for elimit and VLI for vlimit.
So I want to take the income compare it to the income limit table and then return the description
The output would look like this :
29226 128 20577 Almukhtar, Khadijah M 4242.00 eli
26574 128 17980 Archie, Mary 20218.00 vli
I just not sure how to reference the income limit table without the foreign key in the from statement. When I just add it it returns 6 rows for each person (number of rows on the income limit table)
Can we retrieve data from table type variable as an array in oracle key values..
E.g.
ALTER PROCEDURE prn1( @p_prn as KeyValuePair readonly)
-- proc which having parameter table type as parameter
AS
declare @v_formatted_str varchar(50)
BEGIN
set @v_formatted_str = v_formatted_str + @p_prn(1)(1)
END
Hi,
I've a column col1 of image data type in table1. I would like to copy the data from col1 to another image column col2 in table2. Before moving the value, checking has to be done to specify which col1 data from table1 is needed and the destination has to be checked too.
Example: insert into col2
(select col1 from table1 where table1_id =5)
where table2_id =6
Hence bcp wouldn't work. Can anyone suggest me a way to do it. I tried using writetext but then, i've to get data from col1 in a variable, which is not possible. Any suggestions would be very helpful.
Thanks in advance.

The following is my T-SQL programming plan:
-- Create a new table called "Report"
CREATE TABLE Report

SampleID int,
SampleName nvarchar(25),
Unit nvarchar(25),
Acetone decimal(9,3),
Benzene decimal(9,3),
Trichloroethene(9,3),
Xylenes decimal(9,3),
);
-- Insert the data of SampleID and SampleName from dbo.Samples --
SELECT SampleID, SampleName
FROM dbo.Samples
-- Insert the data of Unit, Acetone, Benzene, Trichloroethene, and Xylenes from dbo.TestResults --
I guess I may be able to use the following code:
INSERT INTO dbo.Reort(Unit, Acetone, Benzene, Trichloroethene, Xylenes)
SELECT x????
FROM y????
WHERE z????
(SELECT xxx??
FROM yyy??
WHILE zzz='##??")
GO
I do not know how I can get and use the above planned "subquery" correctly to get the data I want!!?? Please help and give me a delaied instructions or direction to achieve this task.
Thanks in advance,

I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

SO when i try to load from Master table to parent and child table i am using using expresssion like
select B.ID,A.* FROM FLATFILE_INVENTORY AS A JOIN DMS_INVENTORY AS B ON
A.ACDealerID=B.DMSDEALERID AND A.StockNumber=B.STOCKNUMBER AND

If i use this Expression i am getting the current system date data's only from Master table to parent and child tables.
My Problem is If i do this in my local sserver using the above Expression if i loaded today date and if need to load yesterday date i can change my system date to yesterday date and i can run this Expression.so that yeserday date data alone will get loaded from Master to parent and child tables.
If i run this expression to remote server i cannot change the system date in server.
while using this Expression for current date its loads perfectly but when i try to load yesterday data it takes current date date only not the yesterday date data.
What is the Expression on which ever date i am trying load in the master table same date need to loaded in Parent and child table without changing the system Date.
I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon
My Pocket PC application exports signature as an image. Everything is fine when choose Use SQL statements in TableAdapter Configuration Wizard.
main.ds.MailsSignature.Clear();

foreach (string signFile in signFiles)

mailsSignatureRow.Singnature = GetImageBytes(signFile); //return byte[] array of the image.
main.ds.MailsSignature.Rows.Add(mailsSignatureRow);
}
mailsSignatureTableAdapter.Update(main.ds.MailsSignature);
But now I am getting error "General Network Error. Check your network documentation" after specifying Use existing stored procedure in TableAdpater Configuration Wizard.
ALTER PROCEDURE dbo.Insert_MailSignature( @Singnature image )

INSERT INTO MailsSignature (Singnature) VALUES (@Singnature);

For testing I created a desktop application and found that the same Code, same(Use existing stored procedure in TableAdpater Configuration Wizard) and same stored procedure is working fine in inserting image into the table.
Is there any limitation in CF?

I'm trying to figure this out
I have a store procedure that return the userId if a user exists in my table, return 0 otherwise
------------------------------------------------------------------------
Create Procedure spUpdatePasswordByUserId
@userName varchar(20),
@password varchar(20)

Begin
Declare @userId int
Select @userId = (Select userId from userInfo Where userName = @userName and password = @password)
if (@userId > 0)
return @userId
else
return 0
------------------------------------------------------------------
I create a function called UpdatePasswordByUserId in my dataset with the above stored procedure that returns a scalar value. When I preview the data from the table adapter in my dataset, it spits out the right value.
But when I call this UpdatepasswordByUserId from an asp.net page, it returns null/blank/0
passport.UserInfoTableAdapters oUserInfo = new UserInfoTableAdapters();

I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form.
I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.
Hi,This is driving me nuts, I have a table that stores notes regarding anoperation in an IMAGE data type field in MS SQL Server 2000.I can read and write no problem using Access using the StrConv function andI can Update the field correctly in T-SQL using:DECLARE @ptrval varbinary(16)SELECT @ptrval = TEXTPTR(BITS_data)FROM mytable_BINARY WHERE ID = 'RB215'WRITETEXT OPERATION_BINARY.BITS @ptrval 'My notes for this operation'However, I just can not seem to be able to convert back to text theinformation once it is stored using T-SQL.My selects keep returning bin data.How to do this! Thanks for your help.SD

The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.
Thanks,

I want to do something similar to ExecuteScalar in ADO.net but instead in T-SQL.Basically I want to do a query that will return the first value in the table queried and put it into a variable. How do I do this?Thanks in advance.

from orderlineitem e where parentOrderlineitemid is null order by Quantity desc)
In the above query am getting the productnum and quanity and it looks like this
productnum quantity
