I have a prepare and a query function in go and when I place the ? in the search it works fine. When I try and do a contains search with the % I get sql: statement expects 0 inputs; got 1

How can I do this type of query without having the variables directly in the SQL? I want to prevent SQL injection . Thank You for your help.

I am using go version go1.8.1 darwin/amd64 and using MySQL

My Go Code:

stmt, err := dBusers.Prepare("SELECT id, name, email, username FROM users WHERE name LIKE '%?%';")
    if err != nil {
        logging.LogError("Could Not Query All Users: "+err.Error())
        return nil, errors.New("Could Not Query Users")
    rows, err := stmt.Query(name)

    Reposting my comment as an answer so this question actually has one:

    This answer suggests making your parameter argument (in this case, name) include the wildcards instead of the query. So stmt.Query("%" + name + "%"). This still prevents injection, because it's still being sent as a parameter instead of inline with the query.
