在这种简单情况下如何解决缺少泛型的问题

Question

I am creating a simple sql mapper that allows me to create sql mappings at run time because i have no idea how the database schema will be like.

consider the following struct:

type SqlColumn struct {
    name string
    columnType ? //int float etc...
}

what type should i use for the columnType field?

the only way i could think of is to use strings or a const and handle the rest using reflection, am i on the right path?

Answer 1

Use interface{} for this:

type SqlColumn struct {
    name string
    columnType interface{}
}
