2153477 - ADONET: 'Bad TDS response stream received from server. Unexpected token type received: 4' using sqldbgr sprocs - SAP SDK

Symptom

  • The sqldbgr ASE utility is used to debug stored procedures and functions on ASE (Adaptive Server Enterprise).
  • Use of this functionality on the execution of a command causes ASE to send responses back in separate packets while the debugger on another spid is stepping through the procedure code.
  • At one point error is thrown:

Exception Stack: Sybase.Data.AseClient.AseException: Bad TDS response stream received from server. Unexpected token type received: 4.
at Sybase.Data.AseClient.AseDataReader.CheckResult(Int32 res)
at Sybase.Data.AseClient.AseDataReader.RetrieveNextResult()
