How to trace sql query in postgresql
sql.Register("sqlWithHooks", sqlhooks.Wrap(r.Driver(), &Hooks{}))
// Connect to the registered wrapped driver
db, err := sql.Open("sqlWithHooks", ":memory:")
if err != nil {
fmt.Println("error",err)
}
rows, err := db.Query("SELECT id,name,zone_z_id,dimension,price FROM gift_box_z ")
if err != nil {
fmt.Println("inside the error .........................",err)
}
After running this code I am getting an error missing "=" after ":memory:" in connection info string. Can anyone tell me what's wrong with what I've done here?

sql.Open() expects 2 things 'driverName' and 'dataSourceName'. In case of sqlhooks example, they used sqlite as database. Apart from that, they have used go-sqlite3 and if you look closely to file sqlite3.go at line number 886. You would see datasourcename ':memory:' that means we are opting for in-memory utilization of sqlite db.
'dataSourceName' will vary as per the database opted. Its basically means connection string in Data Source Name format.
Reason why this worked
fmt.Sprintf("host=%s port=%d user=%s password=%s dbname=%s sslmode=disable",
host, port, user, password, dbname)
