Update Database row with only modified values via PDO through my own API?

It doesn't make any sense to include all columns into update statments and bind the values/params to the statement. You can have just color field to be in the set stament and give the id in the where clause.

I am encountering the same problem. My current idea is to pass all field values to the update(...) function, and succeed each value with a boolean $update value. Only if a value TRUE is passed in for this valiable, the corresponding field value will be included in the update statement.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
