I wrote a simple test locally, and it passes:
```go
func TestStaticQueryInfo_OverrideBindingFunction(t *testing.T) {
session := createSession(t)
defer session.Close()
if err := createTable(session, "CREATE TABLE IF NOT EXISTS
gocql_test.static_query_info_override (id int, value text, PRIMARY KEY (id))");
err != nil {
t.Fatalf("failed to create table with error '%v'", err)
}
if err := session.Query("INSERT INTO static_query_info_override (id,
value) VALUES (?, ?)", 1, "foo").Exec(); err != nil {
t.Fatalf("insert into static_query_info_override failed, err
'%v'", err)
}
if err := session.Query("INSERT INTO static_query_info_override (id,
value) VALUES (?, ?)", 2, "bar").Exec(); err != nil {
t.Fatalf("insert into static_query_info_override failed, err
'%v'", err)
}
qry := session.Bind("SELECT id, value FROM static_query_info_override
WHERE id = ?", func(q *QueryInfo) ([]interface{}, error) {
values := make([]interface{}, 1)
values[0] = 1
return values, nil
})
iter := qry.Iter()
var id int
var value string
iter.Scan(&id, &value)
if err := iter.Close(); err != nil {
t.Fatalf("query with exposed info failed, err '%v'", err)
}
if id != 1 {
t.Fatalf("Expected id %d, but got %d", 113, id)
}
if value != "foo" {
t.Fatalf("Expected value %s, but got %s", "foo", value)
}
qry.Binding(func(q *QueryInfo) ([]interface{}, error) {
values := make([]interface{}, 1)
values[0] = 2
return values, nil
})
iter = qry.Iter()
iter.Scan(&id, &value)
if err := iter.Close(); err != nil {
t.Fatalf("query with exposed info failed, err '%v'", err)
}
if id != 2 {
t.Fatalf("Expected id %d, but got %d", 2, id)
}
if value != "bar" {
t.Fatalf("Expected value %s, but got %s", "bar", value)
}
}
```
