baseQuery := fmt.Sprintf("SELECT * FROM %s WHERE ", *tableName)

Currently all data is selected Select * from..., however a better implementation would involve using selectively selecting columns instead of all the data, all the time.

The column to be chosen can be chosen selectively in the same way it is chosen in case of the update query!
