Error on Mapping an UDT - Database Discussion Boards

thanks seesharp...but i need it programmatically

Hi,

I have a requirement to select the starting date and ending date of a month if I give a particular date as a parameter. HOw to do that? For eg>
If I give the select statement as below:
select startdate, enddate from <tablename> where particulardate = '17/03/2008'. If I execute this query, I should get the start date as '01/03/2008' and end date as '31/03/2008'

HOw to achieve this in SQL Server? Pls help

Regards
meeram.

Getting End Date
1. Add 1month to the given date taking 1st day and year of given date
2. which returns 1st of next month from given date
3. subtract 1day which returns last day of given month

DECLARE @GivenDate AS DateTime<br />
SET @GivenDate = GetDate()<br />
SELECT DateAdd(DD, -1, DateAdd(MM, 1, Cast(Month(@GivenDate) AS VarChar(2)) + '/01/' + Cast(Year(@GivenDate) AS VarChar(4))))

Getting Start date
similar to the end date take day as 1 with month & year from given date

Regards
KP

Thank you very much

hi,

i have three fields in the database table

p1 p2 rank

10% 20% 3

21% 40% 2

now i am passing the input as 15%...this 15% is related to 3rd rank.. so i need the o/p rank as 3..

if the p1 and p2 datatypes are varchar..then how we can we write the query for that one tgo get the rank as 3.

Ramesh

You haven't explained why a rank of 3 should be returned for 15% However I assume this is because 15% is between 10 and 20%. In this case, you shoul use the BETWEEN clause in your query.

Why are you storing percentages in varchar fields? They are numbers, so they should be stored in numeric fields. You will run into problems every time you want to do numeric comparisons because you will need to case your varchar values to numbers.

Hello..

I've got an InvalidOperationException: invalid Value vor the OracleObjectMappingAttribute nNR

Could NET have a problem with casting NUMBER to int? Or have i to do something
special, because I'm using a OUT-only Parameter?

Here are my code:

PLSQL:
-------------
create type TESTOBJ as OBJECT (
nNR NUMBER;
sTEXT VARCHAR2(20);
)

create testproc(p_testobj OUT TESTOBJ)
as
v_testobj TESTOBJ := TESTOBJ(1,'Test');
begin
p_testobj := v_testobj;
end;

C# the Mapped OBj:
-------------------------------
public class OracleXTBQueueObj : IOracleCustomType
{

private int nr;

[OracleObjectMappingAttribute("nNR")]
public int NR {
get { return nr; }
set { nr = value; }
}

private string tEXT;

[OracleObjectMappingAttribute("sTEXT")]
public string TEXT
{
get { return tEXT; }
set { tEXT = value; }
}

public virtual void FromCustomObject(OracleConnection con, IntPtr pUdt)
{
OracleUdt.SetValue(con, pUdt, "nNR", this.NR);
OracleUdt.SetValue(con, pUdt, "sTEXT", this.TEXT);
}

public virtual void ToCustomObject(OracleConnection con, IntPtr pUdt)
{
this.NR = ((int)(OracleUdt.GetValue(con, pUdt, "nNR")));
this.TEXT = ((string)(OracleUdt.GetValue(con, pUdt, "sTEXT")));
}
}

C# the Factory:
-------------------------------
[OracleCustomTypeMappingAttribute("USR.TESTOBJ")]
public class OracleXTBQueueObjFactory : IOracleCustomTypeFactory
{
public IOracleCustomType CreateObject()
{
OracleXTBQueueObj obj = new OracleXTBQueueObj();
return obj;
}
}

C# the function, callin the PROCEDURE:
------------------------------------------------------------
public static void GetOO(OracleConnection conn)
{
OracleCommand cmd = new OracleCommand("UDT_TESTPROC", conn);
cmd.CommandType = System.Data.CommandType.StoredProcedure;

OracleParameter paramDaten = new OracleParameter("p_testobj", OracleDbType.Object, ParameterDirection.Output);
paramDaten.UdtTypeName = "USR.TESTOBJ";
cmd.Parameters.Add(paramDaten);

try { cmd.ExecuteNonQuery(); }
catch (Exception ex) //InvalidOperationException
{
Console.Out.WriteLine(ex.Message)
}
Console.In.ReadLine();
paramDaten.Value.ToString();

}

I am working on a report which requires me to draw two polygons (rectangles) on a scatter chart to visually indicate "good" and "bad" ranges of plotted data. Is there a way to do this out-of-the-box?

Otherwise, if I must create a custom report item, how do I draw on the chart surface? I have looked at the following articles on Custom Report Items, but when I open the sample solutions I can't put the custom report items on the chart surface.

Do I have to create a custom report item which inherits from a chart control? If so, does anyone have any reference samples?

Mark's blog: developMENTALmadness.blogspot.com

I have used the Dundas Chart for Reporting Services component to solve a similar problem, i.e. applying custom rendering to a Reporting Services chart. The Dundas Chart component exposes a PostPaint event which allows a developer to draw onto the chart surface area. Code is written against the chart control in C#.

The component isn't cheap, but it does open up new possibilities for charting with Reporting Services. It is especially useful when you need to apply your own customizations to a chart that don't come out of the box.

Thanks, that's one of the solutions I am looking at. However, this is the only requirement I have (so far) which doesn't come out of the box. So I'm not sure if I can get approval to purchase a license just so I can draw a couple rectangles. Of course it's beginning to look like my time to develop it myself will cost a lot more than just to license a 3rd party charting solution.

Mark's blog: developMENTALmadness.blogspot.com

Something else I have tried in the past is writing a custom assembly in .NET that internally renders a Reporting Services chart. This can be achieved by using the web services that Reporting Services exposes to programmicically render a report. You could develop a report that simply consists of the chart you want to display. If you request this report through the web service, the data for your report will be returned as a byte array. You can create an image from this data and then use the graphics capabilities in the .NET Framework to alter the image to your requirements. You could create a custom component to do all this by following the Microsoft article.

Hi,

Problem:
I'm using C# 2005. The data type of the bitmap file saved to database is "long binary data". It should be "OLE Object".

Source Code:

Bitmap myBitmap = new Bitmap(@"c:\Picture1.bmp");<br />
OleDbConnection conn = new OleDbConnection("<<My Connection String>>");<br />
conn.Open();<br />
string sql = "UPDATE Table1 SET fldOLE = @fldOLE WHERE fldID = 5";<br />
OleDbCommand command = new OleDbCommand(sql, conn);<br />
command.Parameters.Add(new OleDbParameter("@fldOLE", myBitmap));<br />
int rowsAffected = command.ExecuteNonQuery();

Question:
How can I save Bitmap to database with data type "OLE Object"?

Laugh | :laugh:

Thanks in advance

Hi All,
I am trying to get a file from an Ftp and Copy data (*csv file) on to one of my tables in SQL 2005 database.
I am not sure but SQL server 2005 integration service has a way to create a package that allows me to do this task.

Can any one tell me how to go about it?

your ideas are much appreciated.

Thank you

Use the FTP task to copy the file to an accessable directory, then you can create a data flow task which uses a flat file source, processes the file and then puts the data in the appropriate data flow destination.

Your package designer should resemble this:

<br />
FTP Task --> Data Flow Task<br />

Open the Data flow task (double-click) and it should resemble this:

<br />
Flat File Source --> [intermediate transformations you may need (if any)] --> Sql Server Destination<br />

Just drag the items mentioned to the designer surface, open each item and set the properties needed.

Hi,

Can I total a detail column at group level on reprting services. I can see how I would put a footer in and total from the SQL but I need things totalling down the page at a smaller level.

e.g.

Sales

Product Type

House Product Uk Sales India Sales
DVD 6 10
Oven 7 12

Total 13 22

Garden Trees 10 15
Fences 34 10

Total 44 25

Any help welcome !

Thanks in advance

Hi
i am creating dataTable at runtime and binding rows at runtime . how to insert the all the rows in dataTable to database

Create a Command object which defines the INSERT command then create a DataAdapter object and assign your Command object to the adapter's Insert command. Make sure when you define the data table object to map the datatable's column names to the parameter objects in the insert command you created.

Mark's blog: developMENTALmadness.blogspot.com

the code in my application is:

OleDbCommand com = new OleDbCommand();
com.Connection = con;
com.CommandText = "UPDATE tblUsers SET Password=? WHERE UserName=?";

com.Parameters.Add("UserName", OleDbType.WChar);
com.Parameters.Add("Password", OleDbType.WChar);

com.Parameters["UserName"].Value = this.UserName;
com.Parameters["Password"].Value = this.txtPassword1.Text;

-------------------------------------------------------------------------------

When I run the application , it gives the syntax error in update query.
I am unable to find where I am going wrong
Kindly help me!

Sadaf

Why not you try this:

com.CommandText = "UPDATE tblUsers SET Password='" + this.UserName.Text + "' WHERE UserName='" + this.txtPassword1.Text + "'"

Do good and have good.

Silent Eagle wrote:
com.CommandText = "UPDATE tblUsers SET Password='" + this.UserName.Text + "' WHERE UserName='" + this.txtPassword1.Text + "'"

Shouldn't that be:

com.CommandText = "UPDATE tblUsers SET Password='" + this.txtPassword1.Text + "' WHERE UserName='" + this.UserName.Text + "'"
