comment Selective update of mySQL database column
Have you tried using SQLExecute? I find it easier to use because you can just do straight sql commands. I have also used it with Map as you are trying to do here.

comment Using StringReplace to make file names
I have certainly done that many times before and it works well for a set of plots that are similar and works very well when making an animation for a beamer where I can also have Mathematica write the LaTeX code. But when playing with parameters for plots that have to be manually copied PowerPoint it is nice to have a systematic way of generating human readable file names.

comment Using FindMinimum with matrix input
Obviously I cannot run your code either but here are some ideas. Make sure that your function is returning a scalar and force your inputs to be numbers. energycoeffs[p_?NumericQ,q_?NumericQ,r_?NumericQ]:=energycoeffs[{{p, 0, 0}, {0, q, 0}, {0, 0, r}}] Then minimize energycoeffs[p,q,r]
