QUESTION

QUESTION
I want to override the Stringer interface for all instances sql.NullString so that the output of an instance is instance.String rather than { instance.String, instance.Valid }.
The normal way of doing this is to provide a Stringer interface. With sql.NullString a Stringer interface method fails to compile as there is already a String field.
The workaround is to just use instance.String everywhere.
ANSWER
Answered 2021-Jan-04 at 07:35type NullString struct { ns sql.NullString }
func (s *NullString) Scan(value interface{}) error {
return s.ns.Scan(value)
}
func (s NullString) Value() (driver.Value, error) {
return s.ns.Value()
}
func (s NullString) String() string {
return s.ns.String
}

Currently working on a project in C but I have to generate a large struct which I figured would generate in PHP since I'm more familiar with PHP.
I have 2 arrays. The first one is quite simple (is way larger than this but I assume this is enough to replicate the issue):
...ANSWER
Answered 2018-Aug-11 at 18:36array_column($textures, $item) will search in array $textures key named $item, but there is no key with that name so it returns false, what you need to do is loop on $textures array and search if value $item exists:
QUESTION
I have one column/list filled with appointment information (column A), and another separate column/list of clinician names ( column C). I am interested in simplifying column A down to just a clinician name(its match from column C). Is there a method/approach which could be used to find matches in column A and C, and then list them in column B?
Column A has about 1,100 rows, Column C about 200 rows(names).
