I uploading an image from a web page into Sql Server 2000 database. I call a stored procedure with the parameter @Flag of type Image. When I tried to pass a null value to this parameter I got the error:"Operand type clash: nvarchar is incompatible with image".I was adding the parameter like this:sqlCmd.Parameters.AddWithValue("@Flag", DBNull.Value);After trying few different things I found a workaround using the following:sqlCmd.Parameters.Add("@Flag", SqlDbType.Image);sqlCmd.Parameters["@Flag"].Value = DBNull.Value;Possibly a bug in the SqlCommand.Parameters.AddWithValue method ?
The following is the full error message. I am posting the code after.

I'm new to databases. So I'm writing code in c# to search a database. Here is the following SQL statement I'm trying to use: SELECT Movies.Movie, Movies.Genre, Movies.ReleasedFROM Movies INNER JOIN MovieActor ON Movies.Movie = MovieActor.MovieWHERE (MovieActor.Movie = '% ' & @name & ' %')
When I go to test the statement it says that "Data types varchar and varchar are incompatible in the boolean AND operator." Any ideas around this?

I'm trying to read a data table with all text fields using C# in ado.net. However, when my query runs, it always returns this error:
"The data types text and varchar are incompatible in the equal to operator. "
The SQL statment is "SELECT field1, field2 FROM table WHERE field1 = 'value'"
If I leave out the WHERE clause, it runs fine. There are NO varchar fields in my entire table (It's a test table). I've tried using both parameter objects and Convert (See commented section) with no luck. A packet trace shows the SQL string is being delivered in tact and the SQL server is returning the error. I don't know if it's a C# client issue, or a SQL Server 2005 Exp issue. The table was created using MS SQL Server Management Studio Express I'm currently using the SqlClient object like this:
<script runat="server"> DataSet dsData = new DataSet(); DataTable dtData = new DataTable();
void Page_Load() { string strConn = ConfigurationSettings.AppSettings["authstr"]; string strSQL = "SELECT User_ID, User_Name FROM USERS1 WHERE User_ID = "'bobhope'";
//string strSQL = "SELECT password_fld, pharmacy_fld FROM Esker_Tbl WHERE CONVERT(text, username_fld ) = '@prmuser'"; //SqlParameter spuser = new SqlParameter("@prmuser", SqlDbType.Text);
//string struser = "bobhope"; //spuser.Value = struser; try { SqlConnection Conn = new SqlConnection(strConn); SqlCommand Cmd = new SqlCommand(strSQL, Conn); SqlDataAdapter Adp = new SqlDataAdapter(Cmd);
Trying to use some of the data access samples with VS 2005; the error says that the database is incompatible with this version of sqlsevr.exe, which I think means that SQL Server 2005 can't read the file? I do not have the express edition installed, only SQL Server 2005.
It says "You must re-create the database".
Do I need to install SQL Server Express edition? Will this conflict with SQL Server 2005?
Can I update the express database in SQL Server 2005?
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.
Session("matricN") = Trim(TextBox1.Text) Dim txtValue As String txtValue = Session("matricN") da = New SqlDataAdapter("select MatricNumber,Name, Roles from Register where MatricNumber = " & txtValue, addRoleConn1)
MatricNumber is in varchar(50) datatype,, the errror says there is a syntax near "="
I'm getting this error when trying to insert data into a table.
"Operand type clash: int is incompatible with date"
This is the SQL I used to create the table:
Code: CREATE TABLE customers( customer_id int IDENTITY(1,1) NOT NULL, member_yn char(1) NOT NULL, membership_number int NOT NULL, date_became_member date NOT NULL,
[Code]....
This is the SQL I am using to add data: (Note that there are two dates in each line, scroll to the side.)
Code: INSERT INTO customers VALUES ('y', 156, 2010-08-29, 'John', 'Smith', '1235 Main Street, Dunmore, PA 18512', 6963287654, 'jsmith@hotmail.com', 1986-06-23); INSERT INTO customers VALUES ('y', 159, 04/15/2011, 'Mary', 'Jones', '235 Ardmore Blvd, Pittsburgh, PA 15221', 3429831594, 'jones_mary@gmail.com', 01/12/1992);
Each of the lines above to add data uses a different data format because I tried both, while commenting out the other, hoping for the problem to go away with the change in format.
Here is the SQL code to create a primary key for this table:
Code: ALTER TABLE customers ADD CONSTRAINT pk_customers PRIMARY KEY (customer_id);
declare @fromdate date declare @todate date set @fromdate='2011-12-01' set @todate='2012-11-31' print @fromdate print @todate
Got the error as "Conversion failed when converting date and/or time from character string." then i tried as below
declare @fromdate date declare @todate date set @fromdate=12-01-2011 set @todate=11-31-2012 print @fromdate print @todate
this time got the error as '' Msg 206, Level 16, State 2, Line 3 Operand type clash: int is incompatible with date Msg 206, Level 16, State 2, Line 4 Operand type clash: int is incompatible with date".
Hay Friend's Can u plese send me the way how to save image in sql server and display that images in datagrid or other control also like Image control or Image control Button?? Plese send the coding in C#. Thank's Amit
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 & " "
I have a package that works fine in development. I move the package over to test and it fails validation in the lookup transform.
Error 46 Validation error. Data Flow Task - PO Lines Interface: Lookup - LIST PRICE [29621]: output column "LIST_PRICE_PER_UNIT" (29667) and reference column named "LIST_PRICE_PER_UNIT" have incompatible data types. SPO_TO_ORACLE_PO.dtsx 0 0
What strikes me as odd is the fact that I don't have a way of specifying the data types. I just specify the column I wish to return as a new column with the same name. Anyway, why would this work in one instance but not another?
Hi, If I make a select query on my table, this error appears: "The data types text and varchar are incompatible in the equal to operator"
In my table , I have 4 fields with "text" datatype. My query is like : "Select * from table where field1='test'" It's seems to be simple, but it doesn't work!!!
SELECT TOP 1000 *... case when Rownum<= datediff(day, salesdate, baseenddate) then DATEADD(mm, RowNum, salesdate) /*error at this point*/ else 0 end as subscriptionrowdate FROM Subsrow
Rownum is an integer type. DATEADD is the part when the error is but i dont know how to convert this to int
I have learned lots of informative thing from your forums. I have little problem regarding “Display image from SQL Server on ASP.NET� I have done it and image display on my page from SQL Server. I have cleared you here I have adopt two different methods which are following for displaying picture.
but in both above methods I have faced little problem when image display on my page all other information can not display and I also want to display picture on my specific location on the page. My second question is can use any web control like “Image1� to display image from SQL Server where my pictures are stored.
hi,i have inserted the image present in mydocuments using alter commandcreate table aa(a int, d image)insert into aa values (1,'F:prudhviaba 002.jpg')when i doselect * from aai am getting the result in the column d as0x463A5C707275646876695C70727564687669203030322E6A 7067how i can i view the image?pls clarify my doubtsatish
In my asp.net application I have a local report with an image control in thedetail row of the table and the Value attribute set as="File://" & Fields!FQPhotoFileName.ValueThe first row in the table always shows the wrong image and it's always thesame wrong image. The problem is there even when I change the sort order orthe criteria for the underlying dataset. For example, I ran a small testthat populated the dataset with 2 rows and 2 images. When I sort by anycolumn (e.g. ID) in ascending ascending order the ID=1 row (the 1st row)shows the wrong image and the ID=2 row shows the correct image. When I rerunthe report sorting in descending order the ID=2 row (which is now the 1strow) shows the wrong image and the ID=1 shows the correct image.Any suggestions?
Hi, I have a website and i am uploading the gif image to the database. i have used varchar(500) as the datatype and i am saving the file in the webserver so the path to it c:intepub....a.gif
my upload table has the folliwing feilds UploadId Int Identity, Description, FileName, DiskPath varchar(500), weblocation varchar(500). I have a main sproc for the report where i am doing a inner join with other table to get the path of the gif..
So my question is how can i get a picture to show up on the report. . What kinda datatype the gif file should be stored in the database? If it is stored as a varchar how can i access it and what is best way to reference that particular.
I have inherited a VS 2005 database with a table that has a column of type IMAGE. I need to change the image for one of the rows in the table. I have the new image in a *.PNG file on my C: drive. What is the correct method for inserting this file into the IMAGE column.
Im reading in a CSV wiht double quote text delimiters. Data came from mySQL.
One column in mySql is text(65535) which is equivalent to varchar(max) as far as i understand.
This particular column can be blank, not null, just blank. If its blank i want to put in a value so i added a Derived column shape and added the following formula:
LEN(my_Column) < 1 ? Â "" : Â (DT_TEXT)my_Column
I get the below error from this expression:
 The data types "DT_WSTR" and "DT_TEXT" are incompatible for the conditional operator. The operand types cannot be implicitly cast into compatible types for the conditional operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.
I have tried this without casting but still get an error. As I have configured the column in the flatfile connector as DT_TEXT, im not sure where its getting DT_STR from.
