I'm using the SqlBulkCopy within my asp.net C# web form. I'm able to upload my excel file, but if the first row has any blank cells in it, that colum does not upload, I was wondering if anyone had any luck in looking for NULL/Blank cells and if so how did you handle them for the insert into the database?
View 6 RepliesI am confused by some behaviour I am experiencing when I use the SqlBulkCopy command.I have two tables in my SQL server database that I use to upload 2 tables of data from an excel workbook. The primary key of each table is customer account number, the first table being a table of accounts, the second being a table of details with the account number linking the 2 tables creating a one-to-one relationship.The bulk copy works a treat apart from one rather problematic situation I have found when performing error handling. If I put an account into the details table that does not appear in the customer table, instead of causing key violation errors it still adds the entry - I was under the impression that this was impossible?
If I go edit the entry using SQL Server management studio, I cannot change account numbers to anything that does not exist in the other table thus showing that the relationship exists and works when using standard update SQL.Does anyone have any idea why and how data that violates key violations is allowed through when I use SqlBulkCopy?

View 1 RepliesI'm using SqlBulkCopy to restore tables from xml backups. One of the table backup is ~200MB large and has a lot of records.
I'm having error:

I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:
"The given value of type String from the data source cannot be converted to type decimal of the specified target column."
Here is the StackTrace:

Anyone have any ideas why this will not import correctly?

I am impoting data from CSV file to my sql server database.
I successfully get data into datatable and using the SqlBulkCopy method to import data into database.
It's working fine.
But i want that if record id is exists then update the record do not insert that record.
I have a customized data import executable in .NET 3.5 which the SqlBulkCopy to basically do faster inserts on large amounts of data. The app basically takes an input file, massages the data and bulk uploads it into a SQL Server 2000. It was written by a consultant who was building it with a SQL 2008 database environment. Would that env difference be causing this? SQL 2000 does have the bcp utility which is what BulkCopy is based on. So, When we ran this, it triggered a Deadlock error.
Error details: Transaction (Process ID 58) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
I've tried numerous ways to try to resolve it. like temporarily setting the connection string variable MultipleActiveResultSets=true, which wasn't ideal, but it still gives a Deadlock error. I also made sure it wasn't a connection time out problem. here's the function.

View 1 RepliesI have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:
<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ ConnectionStrings:PgSqlConnection.ProviderName %>" >

As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />

I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
