At work, we use PetaPoco as our ORM and it works great when using strongly typed objects.
However, I have a requirement to allow users (specifically just one user) enter their own queries to return an array of objects that will then be used on the front-end using the PivotTable.js library.
The issue I am running into is that when I go to query the user entered SQL and I pass a dynamic or an object as the type, I get the following exception:
Operation could destabilize the runtime
For reference, this is the code that I'm using:
The Get method is defined as the following:
The Query method ultimately hits the IDatabase's Query method using a List<AdHocQueryViewModel> as the strongly typed object.
I was thinking about writing a wrapper to just return the collection of datarows, but before I started down that path, I wanted to see if anyone else ran into this same issue.

Quote:

Code:
public List<object> ExecuteSql(int adHocQueryId)
{
_database.EnableAutoSelect = false;
var adHocQuery = Get(adHocQueryId);
var results = _database.Query<object>(adHocQuery.Sql).ToList();
_database.EnableAutoSelect = true;
return results;
}Code:
public AdHocQueryViewModel Get(int AdHocQueryId)
{
var filter = new Dictionary<string, dynamic>
{
{ "AdHocQueryId", AdHocQueryId }
};
var records = Query(filter);
if (!records.Any())
{
throw new SystemError($"No record found for AdHocQueryId {AdHocQueryId}");
}
if (records.Count > 1)
{
throw new SystemError($"More than one record found for AdHocQueryId {AdHocQueryId}");
}
return records.Single();
