package database/sql/driver
Queryer is an optional interface that may be implemented by a Conn.
If a Conn does not implement Queryer, the sql package's DB.Query will first prepare a query, execute the statement, and then close the statement.
Query may return ErrSkip.
Golang database/sql/driver.Queryer type usage example
type wrapResults_ struct {
Query string
Values []driver.Value
}
var results = &wrapResults_{}
var dbwrap = New("test", f)
dbwrap.HandleQuery = func(r driver.Queryer, qs string, v []driver.Value) (driver.Rows, error) {
results.Query = qs
results.Values = v
return dbwrap.Driver.(driver.Queryer).Query(qs, v)
}
