ADO.NET :: Convert String To Clob And Declare Clob In C# Function?
Nov 10, 2010
i am having prob with CLOB datatype. i have a table whr i hv declared one field as clob datatype, now i have written a stored procedure for both insertion and updation but the problem is this when i am gng to write the function for both these procedures i don't know how to convert the value which is in string to clob and also how i should declare CLOB datatype in my method or functions.i am using Oracle 10g.i am using Ajax Editor control and want to store its data in CLOB datatype.
I am looking to convert a String (which contain my XML) to Clob type in VB.net 2005 and call a Oracle Store Procedure which return me XML in Clob type and need Convert it back to String.
Please consider below example for better reference..
Below Method Call the Oracle Procedure with String as Input
Private Function Pricing(ByVal sXML As String, ByVal strOutputXML As String, ByVal sStatus As String, ByVal sMsg As String)
Dim objParams(3) As OracleParameter objParams(0) = New OracleParameter("input_xml", OracleType.Clob, 100000) objParams(0).Direction = ParameterDirection.Input objParams(0).Value = myclob objParams(1) = New OracleParameter("output_xml", OracleType.Clob, 100000) objParams(1).Direction = ParameterDirection.Output objParams(2) = New OracleParameter("status", OracleType.VarChar, 100) objParams(2).Direction = ParameterDirection.Output objParams(3) = New OracleParameter("msg", OracleType.VarChar, 1000) objParams(3).Direction = ParameterDirection.Output ExecuteDataset(objOMARConnection, CommandType.StoredProcedure, "PRICING_INT.ITEM_PRICE", objParams)
End Function
ORACLE Procedure
PROCEDURE item_price ( input_xml IN CLOB, output_xml OUT CLOB, status OUT VARCHAR2, msg OUT VARCHAR2
I have a dataset stored as a CLOB field in an Oracle table. I want to be able to pull this field out and type it back to a dataset. Is this possible and if so how?
I have an ASP.NET 4.0 application where I'm using NHibernate 3.0 with ODP.NET (newest version) to access a Oracle Express 10g database. All is working fine except the CLOB column is getting mixed up in my objects.
Example:
Http request /product/1/:
All returned columns values are OK.
Http request /product/2/:
All returned columns values are OK, except the CLOB column. The returned CLOB column is from the previous loaded object.
The problem disappears when disabling connection pooling.
But I'd like to use connection pooling and it doesn't feels right as a solution. Is this a bug in the ODP.NET or are I'm missing some built-in "feature"?
am in deep trouble with retriving the data from oracle database. Please HELP ! In one line: "When i retrive the data from oracle database, it's truncate the data if it is more than 4 kb"I have oracle proc param as below:
PROCEDURE p_GetData ( ivar_id IN id_n%TYPE, oclb_owners OUT CLOB, onum_sqlcode OUT NUMBER, [code]...
Can i save the contents of a word file (which contains some formatted text) in clob field and then retrieve them in their original state i.e can i save the formatted text in clob field like we can save it in blob field?
I've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?
I have a json object collection of geo locations that I build in the server. Each of those objects has two properties: "marker" and "onClick". Marker is for storing a Google Maps marker object and the onClick stores the name of the function to be called when that marker is clicked on the map.When I'm pushing the location objects into an array using javascript in the client side, I create the markers and assign them to each location object within the array.
My problem is that when I bind the marker with the onClick property, the function won't be found in the DOM and get an error.Is there a way to declare a property in a json object for using it on an event binding?
I have the following statement, I want to turn it into a Public Shared Function :
If isEmployee Then Dim employeeInstance As New Employee employeeInstance = GetEmployeeInstanceByUserId(userId) Return employeeInstance Else Dim studentInstance As New Student studentInstance = GetStudentInstanceByUserId(userId) Return studentInstance End If
Public Shared Function GetWorkerInstance(Byval isEmployee as Boolean) As ...(not sure what to write here)...
There two possible return Type. I'm not sure what I should declare for the function return type.

on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings 'We have to convert the object to a connection string Dim rootWebConfig As System.Configuration.Configuration rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec") Dim connString As System.Configuration.ConnectionStringSettings connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1") Dim strConnString As String = connString.ToString().......
I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.
I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d; var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"}; if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d)) { lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text }
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.
My title says it all, I am looking to see if there is any built in class/function that basically takes a number and gives back the number in letters such as 10 to ten.
i am displaying some news from rss feeds in the page. But i am stuck up in the date time conversion. I got th published datetime as pdt formated string. How can i convert to my local time. Coversion from the pdt string tot DateTime is error..
[Code]....
This second line is error and i need the result in the specified format or same format as in the published date but in local time ie IST (India Standard Time)
I have a column as totalsecond in my database i take a avg of tht totalsecond column for the particular parameter and condition and when i come on my aspx page i show that data as hh:mm:ss by converting it with timespan function of dotnet and show this in datagrid but while doing this calculation in DataGrid_ItemDataBind it take so much time and the user have to wait for long time for the result after clicking button show when there is large amount of data.
How can i reduce the time of waiting for the user with some coding logic that speed up the calculation time.
I am tasked with a project to convert words from strings to numbers . I have to do this while ensuring collision-avoidance. i.e training -> 10232323
We are storing the numbers in a database and when we retrieve the records from the database, we will reverse hash and convert the number back to a string 10232323 -> training
As you might have guessed - this is not an area that I am familiar with. I researched the overridable System.Object.GetHashCode() method, but Microsoft warns that there is little guarantee that the default implementation of GetHashCode() avoids collisions.
So I am left stuck. I would like to create an algorithm, but I have no idea where to start.
Also, the function should accept unicode characters - in the event the company decides to internationalize.
