sqlbulkcopy

I am trying to find out how I can improve my insert performance in a temporary table in SQL Server using c#. Some people are saying that I should use SQLBulkCopy however I must be doing something wrong as it seems to work much slower than simply building an SQL insert string instead. My code to create table using SQLBulkCopy is below: public void MakeTable(string tableName, List<string> ids, SqlConnection connection) { SqlCommand cmd = new SqlCommand("CREATE TABLE ##" + tableName + " (ID int)", connection); cmd.ExecuteNonQuery(); DataTable localTempTable = new DataTable(tableName); DataColumn

I have about 6500 files for a sum of about 17 GB of data, and this is the first time that I've had to move what I would call a large amount of data. The data is on a network drive, but the individual files are relatively small (max 7 MB). I'm writing a program in C#, and I was wondering if I would notice a significant difference in performance if I used BULK INSERT instead of SQLBulkCopy. The table on the server also has an extra column, so if I use BULK INSERT I'll have to use a format file and then run an UPDATE for each row. I'm new to forums, so if there was a better way to ask this

I have this code which works fine and loads the excel data into an SQL table. The only problem is that it also inserts a new row with NULL values for all columns. using (OleDbConnection excel_con = new OleDbConnection(conString)) { excel_con.Open(); string sheet1 = excel_con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null).Rows[0]["TABLE_NAME"].ToString(); DataTable dtExcelData = new DataTable(); using (OleDbDataAdapter oda = new OleDbDataAdapter("SELECT * FROM [" + Path.GetFileName(excelPath) + "]", excel_con)) { oda.Fill(dtExcelData); } excel_con.Close(); using (SqlConnection con = new

I have a gridview which will contain some 'n' number of rows.... Now i want to add all rows of the gridview to a datatable which will be used for bulkcopy operation...

Update: Here is my solution I have a table defined as: CREATE TABLE [dbo].[csvrf_References] ( [Ident] [int] IDENTITY(1,1) NOT NULL, [ReferenceID] [uniqueidentifier] NOT NULL DEFAULT (newsequentialid()), [Type] [nvarchar](255) NOT NULL, [Location] [nvarchar](1000) NULL, [Description] [nvarchar](2000) NULL, [CreatedOn] [datetime] NOT NULL DEFAULT (getdate()), [LastUpdatedOn] [datetime] NOT NULL DEFAULT (getdate()), [LastUpdatedUser] [nvarchar](100) NOT NULL DEFAULT (suser_sname()), CONSTRAINT [PK_References] PRIMARY KEY NONCLUSTERED ([ReferenceID] ASC) ) ON [PRIMARY] I have a DataTable with

I want to make one SqlBulkCopy method that I can use for all my bulk inserts by passing in specific data through the parameters. Now I need to do mapping on some of them. I don't know how to make a SqlBulkCopyColumnMappingCollection since that was my plan to pass in the mapping collection in and use it. However I don't know how to make it. I can't make a new object of it. This is what I have now. How can I add it do mapping put pass it in? public void BatchBulkCopy(DataTable dataTable, string DestinationTbl, int batchSize) { // Get the DataTable DataTable dtInsertRows = dataTable; using
