In general XML documents or fragments are held in strings as text markup. In SQL Server, XML variables and columns are instead tokenised to allow rapid access to the data within. This is fine, but can cause some odd problems, such as ' entitization'. What do you do if you need to preserve the formatting? As usual Rob Sheldon comes to our aid.   Read more...

Every so often, the question comes up on forums of how to pass a list as a parameter to a SQL procedure or function. Phil Factor provides some examples using XML, and tests them against other popular methods.  Read more...

XML data can become a full participant in a SQL Server Database, and can be used in views, functions, check constraints, computed columns and defaults. Views and table-valued functions can be used to provide a tabular view of XML data that can be used in SQL Expressions. Robert Sheldon explains how.  Read more...

With the release of Master Data Services (MDS) for SQL Server 2008R2, it is now possible to perform XML transformations on the database server.  Read more...

The XML Data type has definite uses, but the way of interrogating, retrieving, and manipulating the values of properties and attributes within XML have been so foreign to the SQL language as to be somewhat of a barrier to their use. Fortunately, Robert Sheldon has once more managed to make the subject accessible to those of us who just need to get the job done.  Read more...

The XML data type, introduced in SQL Server 2005, is a powerful construct. When used wisely, it can provide useful extensions to SQL Server. Robert Sheldon, in the first part of a series, describes how create and index a XML column in a table, and discusses when you should consider using an XML data type.  Read more...

Package configuration files are a great way of providing the values of SSIS package properties so that packages can be used in a far more versatile way. They make the deployment of SSIS packages easier and can provide parameters that are based on the server configuration, or which change for each runtime. They're easy to understand, especially when explained by Rob Sheldon.   Read more...

Unstructured and XML semi-structured data is now used more than structured data. But fixed structured data still keeps businesses running day in and day out, which requires consistent predictable highly principled processing for correct results. For this reason, it would be very useful to have a general purpose SQL peer-to-peer collaboration capability that can utilize highly principled hierarchical data processing and its flexible and advanced structured processing to support dynamically structured data and its dynamic structured processing. This flexible dynamic structured processing can change the structure of the data as necessary for the required processing while preserving the relational and hierarchical data principles. This processing will perform freely across remote unrelated peer locations anytime and transparently process unpredictable and unknown structured data and data type changes automatically for immediate processing using automatic metadata maintenance.  Read more...

The SQL-92 standard introduced the LEFT Outer Join operation which offers a powerful alternative to standard relational processing to perform full hierarchical processing naturally and inherently. This enables SQL to transparently integrate relational data with XML, IMS and other forms of legacy hierarchical data. This can also allow the so far overlooked integration of IMS and legacy data with the Internet and XML, and visa versa.   Read more...
