Feel free to participate. For many of you out there working in a new way, I'm including a thought of the day on how to cope in this challenging time from [The Action for Happiness Coping Calendar](. My items will be on [my blog](, feel free to share yours. It Depends This editorial was originally published on Mar 25, 2009, and is being re-run as Steve is on vacation. No, it's not a comment on Andy Warren's blog (which used to be called It Depends), but rather a note that the title of this editorial, which DBAs are famous for uttering in response to most any question, also applies to much of life. I was reading one of Joel Spolsky's columns [Inc. Magazine article]( and it struck me that "it depends" applies here very well. He was talking about management and the decision of when to implement middle management for his company, Fog Creek Software. They had been a small company, primarily being run by Joel and his partner, Michael Pryor, as co-CEOs. They made joint decisions and tried to keep an open door policy and encourage people to come talk to them. It didn't work out so well, and I can certainly understand that. Even when I've had a good relationship with management, I've found that there are times you're hesitant to talk to them about something. After all they don't really mean they have an "open door policy" all the time. We all think that we have hard and fast rules, and we do, but we don't have as many as we'd like to think we have. Often what we really have are hard-like rules, that we try to enforce as fast as we can, but sometimes bend or break in response to some situation. In other words, what we do "depends" on what situation. And that's how it should be. We need some rules, we need to enforce them, but we also need exceptions to those rules. We need flexibility in how to apply them, recognizing that the rule exists to handle one, or many situations, but not all of them.

Think you know the answer? [Click here]( and find out if you are right.    Yesterday's Question of the Day (by Greg Larsen) Memory Grant Feedback Memory grant feedback tunes the memory requirements for batch mode queries beginning in 2017 and row mode queries beginning in 2019. In which situations will this feature be helpful? (More than one answer is correct) Answer: When SQL Server incorrectly calculates the estimated row size, Incorrect cardinality estimates Explanation: The answers are 1 and 4. One reason that the memory grant may be incorrect is when SQL Server incorrectly calculates the estimated row size. This might be due to having varchar(MAX) columns that are NULL in the query. SQL Server may also incorrectly estimate the number of rows due to a bad cardinality estimate and then also incorrectly size the memory grant. Answer 2 is incorrect because SQL Server will disable memory grant feedback for the query if the memory grant must be changed over and over. Answer 3 is incorrect because it doesn’t matter if there is a table variable involved.
