missing destination name u.shake_hands_id in *[]*model.ModelName - postgresql

Question

I am getting this error when I am trying to tx.Select from database some data.
missing destination name u.shake_hands_id in *[]*model.ModelName
My Query is something like this:
SELECT u.shake_hands_id as "u.shake_hands_id",u.model_id as "u.model_id"
FROM enquiry_interest u
WHERE u.shake_hands_id=$1
my struct is like
type ShakesHandsModels struct {
ShakeHandsId uuid.UUID `db:"shake_hands_id"`
ModelId string `db:"model_id"`
}

Your query:
SELECT u.shake_hands_id as "u.shake_hands_id",u.model_id as "u.model_id"
...
doesn't produce columns named shake_hands_id or model_id like your struct specifies. The double quotes around the aliases tell PostgreSQL to name the aliases u.shake_hands_id and u.model_id (i.e. the . are part of the alias names rather than acting as delimiters). You don't need the aliases at all, this:
SELECT u.shake_hands_id, u.model_id
FROM enquiry_interest u
WHERE u.shake_hands_id = $1
would be fine as would:
SELECT shake_hands_id, model_id
FROM enquiry_interest
WHERE shake_hands_id = $1
If you must use the aliases for some reason, then don't bother with the quotes:
SELECT u.shake_hands_id as shake_hands_id, u.model_id as model_id
FROM enquiry_interest u
WHERE u.shake_hands_id = $1
or make sure you only quote the right things:
SELECT u.shake_hands_id as "shake_hands_id", u.model_id as "model_id"
FROM enquiry_interest u
WHERE u.shake_hands_id = $1
But really, don't use the quotes at all unless you really need them.
