Just last year I was send on training in Prague – the technology I was training myself in was Parallel Data Warehouse (PDW) from Microsoft, now known as Analytics Platform System (APS). Continue reading →

SQLSaturday Denmark precon registration is live
We’re proud to announce that the registration for precons at SQLSaturday Denmark is now live – we have managed to get some great speakers – and the topics they each talk about, are all really interesting and something that we all use or should use in our daily work with Business Intelligence and Microsoft SQL Server.

SSIS Tip of the day
I’ve just learned a new tip about SSIS that I was not aware of. A tip that I think you all should know about,
When retrieving data via the OLE_DB connection, there are several options to how the data should be retreived. Often we just select “Table or View” option, mostly because we’re to lazy to write up the SQL that is needed for the operation.
Just be aware that when you do that, the SSIS engine will use the command OPENROWSET to get the data, but when you’re typing up the correct SQL to get the data and using the “SQL command” the SSIS engine will use the faster and more optimized SP_Executesql.
