有没有办法将2D slice插入sqlite数据库？

I have requirement where the request json can be parsed using 2d slice and I can get each field of the 2d slices by iterating over them. But how can I push that slice to sqlite database and get it back as a 2d slice. Here is my sample JSON:

{
    "emailList": [
        [
            "akki@gmail.com",
            "bakki@gmail.com"
        ],
        [
            "lakki@gmail.com",
            "jakki@gmail.com"
        ]
    ]
}

and here is my sample struct:

type User struct {
    EmailList [][]string `json:"emailList"`
}

Now I have write a go code which reads the sample json parses it using the given struct and insert it into sqlite db. Also read the record from DB and construct the JSON from the record.
