In the ETL project often encounter such a situation:A column in the target table originates from a different source data table A,b,c. If no valid data in A is taken from B, if none in B is taken from C, then set to null if none is in C.In situations like this, sometimes the first thought is the case and then else end, which can solve the problem, but it's still more complicated and error-prone, especially when someone looks at the SQL you're writing.So is there a better way?That's the COALESCE f
