If you are familiar with XML formats you can create the schema in Notepad if not you can use XML Notepad 2007 to create the schema file. This applies to both tag structure as well as data incompatibilities (i.e., an alphabetic character in an integer field). It defines the expectations of both the preparer and recipient, so an attempt to validate an improperly formatted XML file against a XSD file will result in failure. The XML Schema Definition file (XSD) is simply a blueprint of the XML file structure and is recommended by the World Wide Web Consortium (W3C) as a standard for defining XML files. To house the information we create the following table and XML file: CREATE TABLE dbo.tbl_ComputerInventoryĬlick here for a sample XML file for the table above How you provide the opening and closing tag is up to you and the file creatorĪs an example we will import an XML file consisting of simple computer inventory data into a SQL Server instance. Each tag must have an opening and closing tag.There are nodes that can be one level or more.This tag can simply be called "ROOT" or other meaningful name There must be a ROOT tag that encloses the dataset.Although not required, there is usually a declaration in the first part indicating the XML version and encoding.In order for an XML file to be readable it must be what is called "well-formed". But both the file creator and file recipient must use, and be looking for, consistent tag naming. Since XML technically stands for "eXtensible Markup Language", tags can be named pretty much whatever you want them to be named. XML files follow a format similar to HTML in that data is enclosed within a hierarchical tag structure. You no doubt already know the structure of your database, as well as the format of the files you've previously uploaded. Let's review the steps required to develop an XML Bulk Load strategy. In concept bulk loading XML files is fairly simple, although you must be familiar with the structure of XML files, XML schema language, and Visual Basic Scripting. SQLXMLBulkLoad is part of SQLXML, which was originally created after the release of SQL Server 2000 to provide a bridge between SQL Server and XML data. Thankfully there is a method available to assist with bulk importing XML files-that method is using SQLXMLBulkLoad. While being flexible in how it can be developed, it is rigid in its acceptance of data on the receiving end. XML is one of the most common mechanisms for data transfer, so it's no surprise that XML files are being used.
