FieldA.Eq未定义(类型cqlc.BooleanColumn没有字段或方法Eq)

Question

我正在使用cqlc查询cassandra。当我尝试运行SELECT语句时

ctx := cqlc.NewContext()
iter, err := ctx.Select().
From(X).
Where(
X.A.Eq(true),
X.B.Eq(cityID)).
Fetch(c.session)

它向我抛出以下错误

X.A.Eq undefined (type cqlc.BooleanColumn has no field or method Eq)

X.A是布尔列

Answer 1

类型BooleanColumn

type BooleanColumn interface {
Column
To(value *bool) ColumnBinding
}

---

类型EqualityBooleanColumn

type EqualityBooleanColumn interface {
BooleanColumn
Eq(value bool) Condition
}

X.A.Eq undefined (type cqlc.BooleanColumn has no field or method Eq)

这是真的。
