In the Importing XML Data into MySQL Tables Using a Stored Procedure article, Rob Gravelle outlined some ways to work around MySQL's restrictions on stored procedures to import XML data into your MySQL database tables. Today's article covers how to use a Prepared Statement, including error handling and validation, as well as handling additional XML formats.
With a product as complex as Oracle some bugs are bound to be present. Some of these bugs are show-stoppers, and others aren't, but it does teach you to pay careful attention to the results a query delivers. Even though queries are syntactically and logically correct you can't be certain that Oracle won't do something 'behind the scenes' that can produce the wrong answer.
Marcin Policht reviews security related challenges of Microsoft Azure Software as a Service-based SQL Database, focusing in particular on the SQL Server and database-level firewall access control functionality and methods that can be employed to implement it.
Greg Larsen provides a quick primer of the new Dynamic Management Views (DMVs) to help you better understand and manage your In-Memory OLTP tables and your Instances that support In-Memory OLTP tables.
Do you really need an RMAN catalog to successfully recover your Oracle database? There are those that think so -- but they would be wrong. Read on to find out what you need to recover your database without a catalog.
PowerShell provides a command-line shell and scripting language (built in the .NET Framework) especially designed for administrative task automation and configuration management. Read on to learn how to manage Windows services related to SQL Server, either on a local machine or remote machine, using PowerShell cmdlets.
Load tests give the database administrator (DBA) quite a lot of valuable information and may make the difference between poor and acceptable application performance. But what about a big data environment? Are there any gotchas or traps associated with big data?
In theory, it would seem that a stored procedure would be the perfect vehicle for importing XML data from a file, and yet, the LOAD XML INFILE statement cannot be run within a Stored Procedure. Fortunately, there is a way to get around this limitation.
In Release 11.2, Oracle has provided three improvements to earlier attempts at controlling parallel execution. These improvements make this feature more manageable, more scalable, and less likely to saturate server resources, such as memory and CPU, than earlier releases of the database. David Fitzjarrell discusses the first of those improvements, parallel statement queuing.
While using a custom SSIS-based project to upload content of an arbitrarily chosen table from an on-premise SQL Server database to Azure PaaS-based SQL Database provides the most flexibility its inherent complexity might not be justified in more simplistic scenarios. Marcin Policht presents an alternative approach that addresses this concern by employing the bcp utility, which not only eliminates the need for any custom development, but also rivals SSIS in terms of its data transfer efficiency.
