i am trying to upload an excel to an oracle data base (10g xe) the excel has arround 46000 rows.I am getting the following error when i do a insert
ORA-06550 string 1 line 1,

My web app is allowing the user to load a column of data from an Excel spreadsheet. For whatever reason, as it parses the data, fields that are just integers are coming up as System.DBNull. (Code in VB.NET but I work with C# as well, so feel free to post C# solutions)
[Code]....
dataRow(0) is System.DBNull when the Excel file has a number in Column A. Here's what the Excel looks like
Column A
100S200
WEIRD
ABCDEFG
123456
100S12791
119655902
100S12792
105E17530
123456 and 119655902 come through as DBNull

View 1 RepliesI have an excel sheet that contains around 30,000 rows and 18 colmns. These no of rows and columns may increase in future. I need to read all these records from excel sheet and insert into a table in sql database. For reading the excel book I am using Oledbconnections. The possible solutions I have known as per my knowledge, to insert the data are
1. To insert one record at a time which makes 30,000 database hits. How will this affect the performance?
2. To use liked servers - bu this is not working for me.I do not have database permissions to use linked servers. So, the only option i have is the first one.
I have a page within our site that allows admin users the ability to upload configuration settings into the system instead of submitting 1 at a time.
While testing yesterday, i found that one of the upload pages allowed me to upload a excel file that had alot more columns than expected and when i checked the database, the first few columns that were expected took the values from the file, and everything else was ignored, but wanted to see if there is any way to check the number of columns in the file to make sure it matches the upload logic before accepting it.
I need to be able to have a user upload an excel file, then immediately work with that file and save the contents in a database.
I know how to do this if I save the file first, then open it using OleDB, BUT I would rather not save it first.
I would like to upload a xlsx file to Oracle DB (Oracle 11g). I'm using VS .NET 2008 (C#, web).
The file contains around 500 rows.
I have a simple export to excel functionality in my application. Code is :
[Code]....
I need to upload an excel file using a web application. Then I need t oread it in memory without saving it on the server.
Does the file need to have headers? Also the data is such that it may have or may not have values for some columns.
We have the data in excel file and want to upload the same into Oracle table.To achieve this we are using following query
insert into [ODBC:Driver={Microsoft ODBC for oracle};connectionstring].tablename (select * from sheet$ )
This is working fine for less records but when the record count increases following is the error faced. Error : System Resource Exceeded
We tried the following:
1. We tried to remove connection pooling for oracle.
2. We tried to remove connection pooling for excel.
3. We also verified that only one connection for each (oracle and excel) is open.
Our assumptions:
1. Either the server setting is the issue
2. Jet oledb Driver is the issue.
Is there a way to use RangeValidator for large numbers (Int64 range)?
View 1 RepliesWith reference to the following thread: URL....I have problem applying the same concept to gridview EditItemTemplate. Is there a way i can add comma to large numbers and display it in currency format like exemple below:
Textbox3=Textbox1 * Textbox2
Textbox3= 1,000.00
Textbox3 should happen OnTextChanged and the above controls are in Gridview edit mode.
How can i calculate the sum of two textboxes(Textbox1 and Textbox2) and then add comma with .00 to another textbox(Textbox3). Example say Textbox1 = 2 and Textbox2 = 500
Textbox3=Textbox1 * Textbox2
Textbox3= 1,000.00
Note: Textbox3 should happen onkeyup ...

View 1 RepliesI have a excel xlsx workbook that needs to be loaded into various SQL tables after the file's data has gone though various business logic checks. There can be multiple excel files as input to the program so i'm using the standard connection string and a data adapter to append the entire sheet into a DataTable so all the data can be checked at the same time. The code below works for this (sort of).
excelCon = new OleexcelCon = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + strFileName + ";Extended Properties="Excel 12.0;HDR=No;IMEX=1";");
excelCon.Open();
strExcelSheetNames = GetSheetNames(excelCon);
for (int x = 0; x < strExcelSheetNames.Length; x++)
{
excelCmd.CommandText = "SELECT * FROM [" + strExcelSheetNames[x] + "]";
excelCmd.CommandType = CommandType.Text;
excelCmd.Connection = excelCon;
excelAdapter = new OleDbDataAdapter(excelCmd);
excelAdapter.Fill(dtExcelConvert);
}
I'm having an issue with the number columns however, if the number in the xlsx file is 612561120001 and it's displayed as 6.12561E+11 when i read it from the data table and convert it to a number it appears as 612561120000. I have tried to convert the file to a csv file and read it in but they're comma's in a lot of the fields which cause issues when splitting the data.
I am generating, using a ASP routine, Visual Basic, a HTML table in a file to be read by MS Excel.
After Excel reads the file, some of the numbers (in some cells) are shown as "text", not numbers: they cannot be operated upon, like decimal numbers. (added, subtracted...)
If I click in a "number" stored as "text" cell, I can "edit" the cell and remove an invisible "apostrofe" to the left of the number; after that, the "text" becomes "number" again.
Seems like Excel is inserting a non-visible character before the number, so that it is stored as "text"
It happens to some lines and not to others...
Iam exporting dataset to excel , the numbers on the sheet shown as text when export it to excel. Here is the code:

Can you tranfer the data from Excel to another Excel using Asp.net 3.5 without saving it to database.

View 2 RepliesWhat is better way to large upload file.using a web service or in application itself.If in application, how can we check that files is to upload in a regular interval.actually i dont want user to wait for complete uploading, when it starts uploading user will get response of uploaded and uploading will be done in backgroud.I am not sure this type of task can be done in webservice also so that user doesnot need to wait for complete uploading.and one more query which event fires when the page redirects to another page.Is it Page_UnLoad or Dispose

View 1 Repliesinternet Explorer cannot display the webpage when trying to upload a large image.I have a webform for inserting images. There are four FileUpload controls on the page, allowing the user to upload 4 images at the same time. It inserts them directly into database, in Image field, but before that I am resizing them to 200px x 160 px.
The problem I am having is as follows: If I try to upload larger images (over 2MB), one at the time, everything goes fine. But if I try to upload 2 or more larger images at the same time, I get the message: Internet Explorer cannot display the webpage, and there is a button below: Diagnose Connection Problems.
Can you please point me to what could be an issue? It obviously has something to do with the image size, but I have no idea what.
We use the MojoPortal to a website and have some problems to upload files that is around 100 MB with the upload module. (Pleas note that this has probably nothing to do with MojoPortal but with the ASP.NET and the IIS)
The MojoPortal is set to use regular file Upload(not Neat Uploader) and to be able to upload big files we have set the following :
<httpRuntime maxRequestLength="2097151" executionTimeout="18000" requestValidationMode="2.0"/>
And :
<compilation debug="false" defaultLanguage="C#" targetFramework="4.0">
The problem is that the upload will cacel after a couple of minuts (Aborted).
Is there any other values that I need to set to make this possible? The MojoPortal itself should not have any settings for this as far as I know so its regular ASP.NET 4.0.
