Bug in queries.MakeStructMapping when boil tag is boil:",bind"

[sarthak]

What version of SQLBoiler are you using (sqlboiler --version)?

SQLBoiler v4.10.2

What is your database and version (eg. Postgresql 10)

Doesn't matter

If this happened at runtime what code produced the issue? (if not applicable leave blank)

type struct JoinStruct {
  A struct {
    ColA string `boil:"cola"`
    ColB string `boil:"colb"`
  } `boil:",bind"
}

queries.MakeStructMapping(reflect.TypeOf(JoinStruct{}))

Further information. What did you do, what did you expect?

I expect bind mapping to be a map of form {"cola": .., "colb", ...}.
But in reality the map is of form {"a.cola": ..., "a.colb"}.

Thus the bug is that boil:",bind" behaves identical to boil:"<fieldname>,bind".

How to fix?

These lines are buggy --

sqlboiler/queries/reflect.go

Lines 395 to 400 in 644d45d

	tag, recurse := getBoilTag(f)
	if len(tag) == 0 {
	tag = unTitleCase(f.Name)
	} else if tag[0] == '-' {
	continue
	}

Suggested patch is to replace if len(tag) == 0 if if len(tag) == 0 && !recurse.
