I have a DataTable varriable in C# and I want to insert it to a ##TempTable in SQL Directly. I dont want to do like insert into ##TempTable row by row.
How can I do that ?
Select Into ##TempTable from (C# DataTable) ?
Or I m asking in a different way: how can we send a dataset to SQL in a Query from C#?
Note: I m using SqlClient, and SqlHelper classes
Just in case anyone has the same requirement. Any comment is welcome. Code in VB.
Private Sub Connect(srcDT As DataTable, spParameter As String)
Dim conString As String = GetConnectionString()
Dim oSqlConnection As SqlConnection = New SqlConnection(conString)
Try
Dim oSqlCommand = New SqlCommand("Create Table #STG1 (
[Username] [nvarchar](100) NULL,
[FirstName] [nvarchar](100) NULL,
[LastName] [nvarchar](100) NULL,
[Active] [bit] NULL,
[Department] [nvarchar](100) NULL
)", oSqlConnection) With {
.CommandType = CommandType.Text,
.CommandTimeout = 0
}
oSqlConnection.Open()
oSqlCommand.ExecuteNonQuery()
Dim oSqlBulkCopy As SqlBulkCopy = New SqlBulkCopy(oSqlConnection) With {
.DestinationTableName = "#STG1"
}
oSqlBulkCopy.WriteToServer(srcDT)
Dim command As New SqlCommand("spName", oSqlConnection) With {
.CommandType = CommandType.StoredProcedure
}
command.Parameters.AddWithValue("@inParam", spParameter)
command.ExecuteScalar()
Finally
oSqlConnection.Close()
oSqlConnection.Dispose()
End Try
End Sub
