SQL #53 – Keyboard shortcut Alt + F1 works now in SSMS 2012

Keyboard shortcut Alt + F1 works now

SSMS has a rich set of keyboard shortcuts that works by default. But in SSMS 2008 I had one complain about the default Alt+F1 shortcut. The Alt+F1 shortcut is assigned to sp_help by default.  It worked for tables, sort of. If you are… Read more

MDX # 40 – CROSS JOIN does not return Cartesian product of two hierarchies from the same dimension



Thanks to Chris Webb’s comment (see the comment section). I am making a correction on this blog.

MDX+SSAS #37–Ignore unrelated dimension or not

In Adventure Works cube 2008 or 2012, in the Dimension Usage tab, you will see that many intercepts of measure groups and dimensions are blank. To a specific measure group, the dimensions that have blank intercepts are un-related to the measure group. As a matter of fact you will see… Read more

SSIS #116–What is the variable value at runtime?

MDX+SSRS #34 – Query not returning results: there are good reasons

When we are learning MDX, we unavoidably have to deal with the tools we use. Adding confusions about the behaviors of the different tools to our still fragile understanding of the MDX language itself can create huge frustration for learners.

SQL #51 – Timeout when updating a big table

A co-worker recently asked me why she would get timeout when updating a column in a big table. This column will be updated to 0 (zero) because a default value of 0 (zero) constrain is now added to the table.
