Okey, I now read your comment more thoroughly @davecramer and the "Slightly different table works fine"

Do you mean that you can reproduce the error with our table design but not with your table design ? If so, that is not a proper hotfix for us and this error occurs occationally for other tables with other layout as well. It ends up with this error even if you're doing a SELECT with a non existing table.

However, here's some code that reproduces the error. Compiled with Visual Studio 17.12.0 Preview 2.0 and /std:c++latest (in case the `std::println()` function doesn't work)

```cpp
#ifdef UNICODE
#undef UNICODE
#endif

#include <windows.h>

#include <sqltypes.h>
#include <sqlext.h>
#include <sql.h>

#include <cassert>

#include <print>


void evaluate(const SQLUSMALLINT type, const SQLHANDLE handle, const SQLRETURN result)
{
   switch(result)
   {
   case SQL_SUCCESS:
   case SQL_SUCCESS_WITH_INFO:
      break;
   default:
      SQLCHAR state[5 + 1] = {0};
      SQLCHAR message[SQL_MAX_MESSAGE_LENGTH + 1] = {0};
      SQLSMALLINT length = sizeof(message);

      SQLGetDiagRec(type, handle, 1, state, nullptr, message, length, &length);

      std::println("{} [state={}] [result={}]", (const char*)message, (const char*)state, result);

      assert(false);
   }
}


int main()
{
   SQLHANDLE environment;
   evaluate(SQL_HANDLE_ENV, environment, SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &environment));
   evaluate(SQL_HANDLE_ENV, environment, SQLSetEnvAttr(environment, SQL_ATTR_ODBC_VERSION, reinterpret_cast<void*>(SQL_OV_ODBC3), 0));
   SQLHANDLE connection;
   evaluate(SQL_HANDLE_DBC, connection, SQLAllocHandle(SQL_HANDLE_DBC, environment, &connection));
   evaluate(SQL_HANDLE_DBC, connection, SQLDriverConnect(connection, NULL, (SQLCHAR*)"DSN=TestPG", SQL_NTS, NULL, 0, NULL, SQL_DRIVER_NOPROMPT));
   SQLHANDLE statement;
   evaluate(SQL_HANDLE_STMT, statement, SQLAllocHandle(SQL_HANDLE_STMT, connection, &statement));

   SQLSMALLINT number = 0;
   long page = 25;
   evaluate(SQL_HANDLE_STMT, statement, SQLBindParameter(statement, ++number, SQL_PARAM_INPUT, SQL_C_SLONG, SQL_INTEGER, 0, 0, &page, sizeof(page), NULL));
   long size = 25;
   evaluate(SQL_HANDLE_STMT, statement, SQLBindParameter(statement, ++number, SQL_PARAM_INPUT, SQL_C_SLONG, SQL_INTEGER, 0, 0, &size, sizeof(size), NULL));

   SQLCHAR sql[] = R"(SELECT "Id" FROM "ServerSession" ORDER BY "Begin" ASC OFFSET ? ROWS FETCH FIRST ? ROWS ONLY)";
   evaluate(SQL_HANDLE_STMT, statement, SQLExecDirect(statement, sql, sizeof(sql)));

   return 0;
}
```
