Ios 如何在swift中为SqLite返回多个行或表？

我正在为swift使用SqLite库。我可以用这个方法返回一行

  func getById(id:Int64) -> Row?{
        do{
            let query=Users.filter(Id==id)
            print(query.asSQL())
            var data = try db!.pluck(query)
            return data
        }catch{
            print("Error: \(error)")
            return nil
        }
    }

此函数正在返回“

行”

”正常。但我使用的是tableView对象，所以我需要一个数据源

如何返回table并为tableView设置数据源，我还没有找到这样的示例

致以最诚挚的问候。

您可以使用以下代码：

我不知道所有的类，但这是获取SQLite3查询（swift）的主要方法，检查所有结果（如果有多个），附加它们并在最后返回整个数据

//You say you want to return array of rows
func getById(id:Int64) -> [Row]? {
    //Create empty array
    var data = [Row]()
    //build the query. I use UsersTable.entityName.filter(), but I don't know your structure
    let query=Users.filter(Id==id)
    do {
        //for cycle to go to all of the results
        for rowInfo in try db!.pluck(query) {
            //Create variable. I don't know what you want. You can create it as Row() and after that add the information
            let userData = Row()
            //you need to use rowInfo, it store the SQL data. inside the key is from the table Structure. You used Users.filter, so I guess the struct with all column names is Users, so Users.name is the 'name' column
            userData.name = rowInfo[Users.name]
            //Apend the data
            data.append(userData)
        }
    } catch {
        return nil
    }
    //Return the array of Rows
    return data
}
