So help me understand what is happening here.
You have a day model. The day model contains a month and a year.
So you want to get all days for a given month and a year, then find the minimum value of the evotranspiration in that month.
Do you have a staging/test server where I could look at the query and fix it for you?
Yes, I read the query over and asked specific questions about it, so of course you know I sent it... Okay, if you need any help in the future let us know.
