Hi Andreas,
could you elaborate a little on why not to use capital letters for field
names? Recently I started using capital letters for fields, cause for me,
any expressions and codes becomes much better readable.
(Which also reminds me, that a lot of processing functions change field
names to upper case or lower case or leave them as is, totally
unconsistenly.)
Cheers

Hi Phil,
In addition to COALESCE I'd like to promote the use of the function
CONCAT() which treats NULL values as empty strings >>(it was changed
recently, it's probably since 2.10) what makes it very handy.
Example:
NULL || "hello" -> NULL
vs.
CONCAT( NULL , "hello") -> "hello
vs.
COALESCE( NULL, "" ) || "hello" -> "hello"
Cheers,
Matthias

Chances are I will be doing this regularly so I am keen to document
