sqlbulkcopy

I have to get the IDENTITY values from a table after SQLBULKCOPY to the same table. The volume of data could be thousands of records. Can someone help me out on this ? Disclaimer : I'm the owner of the project Bulk Operations In short, this project overcomes SqlBulkCopy limitations by adding MUST-HAVE features like outputting inserted identity value. Under the hood, it uses SqlBulkCopy and a similar method as @Mr Moose answer. var bulk = new BulkOperation(connection) // Output Identity Value bulk.ColumnMappings.Add("CustomerID", ColumnMappingDirectionType.Output); // Map Column bulk

I want to transfer a large amount of data from F# to an SQL table. Basically my F# code creates a matrix of three columns ( UserID, ProductID and price ) and N lines. I would like to "copy/pate it" into a database I tried several options but at the end, the transfer of data from F# is really slow (around one hour for 10000 lines). Thanks to answers of a previous question How to include a stored procedure in F# , an interesting way to resolve this problem is to use SqlBulkCopy . SqlBulkCopy requires a database type for its WritetoServer method but I didn't find any existing code or simple way

I feel embarrassed to ask this question as I feel like I should already know. However, given I don't....I want to know how to read large files from disk to a database without getting an OutOfMemory exception. Specifically, I need to load CSV (or really tab delimited files). I am experimenting with CSVReader and specifically this code sample but I'm sure I'm doing it wrong. Some of their other coding samples show how you can read streaming files of any size, which is pretty much what I want (only I need to read from disk), but I don't know what type of IDataReader I could create to allow this.

After reading in an excel-sheet (to transferTable), I want to add that data to a new table (destinationTable) using SqlBulkCopy, but I'm getting the error: Cannot access destination table 'test' I've tried using the default tablename and using square brackets, but that didn't work. Any suggestions? private void writeToDBButton_Click(object sender, EventArgs e) { MakeTable(); destinationTable.TableName = "test"; testDBDataSet.Tables.Add("test"); // Connects to the sql-server using Connection.cs SqlConnection connection = Connection.GetConnection(); using (connection) { connection.Open(); //

When copying data from a file, you get the count of rows in psql with the "command tag": db=# COPY t FROM '/var/lib/postgres/test.sql'; COPY 10 I need the number of rows and would like to avoid a redundant count() on the table. Is there a way to get this count from COPY directly in a PL/pgSQL function? As far as I know there is none, but maybe I am missing something? For PostgreSQL 9.2. But any option in any version would be of interest. Not in PG 9.2, but there is in PG 9.3 courtesy of Pavel (E 1.3.1.7): Allow PL/pgSQL to access the number of rows processed by COPY (Pavel Stehule) The command

I am familiar with the C# SqlBulkCopy class where you can call the 'WriteToServer' method passing through a DataTable. My question is what underlying mechanism in SQL server is used to bulk insert that data? The reason I ask is that the bulk insert referenced in the Bulk Insert MSDN T-SQL help file requires a data file to import. Does the SqlBulkCopy create a data file? I would like to understand this stuff to work out whether I can use the bulk insert functionality in SQL. If I write a SQL statement that prepares all the rows to insert into a particular table (thousands of rows) can I bulk
