Someone wrote with a reference to a mailing list posting I&#39;d written in 2000, about IRowsetFastLoad. They wanted code, because nowadays attachments to public postings have become a thing of the past. Looked in my OLE DB code, from back when I was teaching &quot;Essential OLE DB&quot;, and &#8230; voila. (I know there&#39;s a code sample in SQL BOL, and told the letter writer about it, but finding the original code was way more fun. Written in ATL and all, too.\n<\/p>\n<p>\nThe poster wanted to know what I&#39;d recommend instead, if this didn&#39;t work out (his inserts are too slow). Choices that came to mind were:\n<\/p>\n<p>\n1. BULK INSERT SQL statement<br \/>\n2. BCP API in C &#8211; it&#39;s ODBC-based IIRC<br \/>\n3. SqlBulkCopy class from ADO.NET 2.0\n<\/p>\n<p>\nThere&#39;s something for choices #1 and #3 in the new SQL Server 2005\/ADO.NET 2.0 stuff. Of course SqlBulkCopy (misnamed, it&#39;s it actually more like IRowsetFastLoad) is new in ADO.NET 2.0. And BULK INSERT has been enhanaced\/rewritten as a &quot;rowset provider&quot;, an OLE DB-like provider whose name is &quot;BULK&quot;. The enhancements are more functional than speed-based. I haven&#39;t done speed tests (it&#39;s too early) but someone posted on newsgroups in Beta 1 that &quot;BULK&quot; was actually slower than the old BULK INSERT. It&#39;s supposed to be as fast by RTM. The new BULK supported XML inserts also, include multiple XML documents separated by &quot;row separator characters&quot;. Think CSV files of XML data type. Whew&#8230;\n<\/p>\n<p>\nThis caused me to wonder if the new SQL Native Client OLE DB provider (SQLNCLI)&nbsp;supports IRowsetFastLoad too. Hmmm&#8230;.says in BOL that there is not only IRowsetFastLoad but an IBCPSession interface on the new SQLNCLI provider. Maybe something for choice #2 also.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I had an interesting flashback today.
