Sqlx Get with prepared statements - postgresql

Question

I am trying to fetch some data from postgress table using prepared statements
If I try with database.Get() everything is returned.
Table:
create table accounts
(
id bigserial not null
constraint accounts_pkey
primary key,
identificator text not null,
password text not null,
salt text not null,
type smallint not null,
level smallint not null,
created_at timestamp not null,
updated timestamp not null,
expiry_date timestamp,
qr_key text
);
Account struct:
type Account struct {
ID string `db:"id"`
Identificator string `db:"identificator"`
Password string `db:"password"`
Salt string `db:"salt"`
Type int `db:"type"`
Level int `db:"level"`
ExpiryDate time.Time `db:"expiry_date"`
CreatedAt time.Time `db:"created_at"`
UpdateAt time.Time `db:"updated_at"`
QrKey sql.NullString `db:"qr_key"`
}
BTW i tried using ? instead of $1 & $2
stmt, err := database.Preparex(`SELECT * FROM accounts where identificator = $1 and type = $2`)
if err != nil {
panic(err)
}
accounts := []account.Account{}
err = stmt.Get(&accounts, "asd", 123)
if err != nil {
panic(err)
}
The error I get is
"errorMessage": "scannable dest type slice with \u003e1 columns (10) in result",
In the table there are no records I tried to remove all fields except the ID from Account (struct), however it does not work.

Documentation for sqlx described Get and Select as:
Get and Select use rows.Scan on scannable types and rows.StructScan on
non-scannable types. They are roughly analagous to QueryRow and Query,
where Get is useful for fetching a single result and scanning it, and
Select is useful for fetching a slice of results:
For fetching a single record use Get.
stmt, err := database.Preparex(`SELECT * FROM accounts where identificator = $1 and type = $2`)
var account Account
err = stmt.Get(&account, "asd", 123)
If your query returns more than a single record use Select with statement as:
stmt, err := database.Preparex(`SELECT * FROM accounts where identificator = $1 and type = $2`)
var accounts []Account
err = stmt.Select(&accounts, "asd", 123)
In your case if you use stmt.Select instead if stmt.Get. It will work.
