• Visual C# What's the difference between += and =+?

  Is there a difference between the valid += and the mysterious =+ They both compile, is this correct As mentioned, the unary plus operator is the complement of the unary minus operator. For unary minus: n = 42; n = -n; // n is now -42 For unary plus: n = 42; n = +n; // n is still 42 The unary plus operator is a NOP, but included for mathematical completeness, as far as I understand. ...Show All

• SQL Server Trying to do too much in a view... I think?

  Hello all, I have a table that contains a whole bunch of clinical statistics. There are some other fields I would like to add, but they are best created on the fly, so I thought I would do this with a view. I can create some of my dynamic fields (like BMI below), but when I try to use them again in the view it doesn't work. (ie, I get an error when I try and include the case statement bit). Does anyone know what I can do Kitty. CREATE VIEW dbo.vAAA AS SELECT BMI = (WEIGHT / POWER((HEIGHT/100), 2)), BMI_GROUP = CASE WHEN BMI < 26 THEN 0 WHEN BMI >= 26 THEN 1 ELSE NULL END -- other bits removed ...Show All
