Token Stream Parameter Details:

 Parameter

 Description

TokenType

DONEINPROC_TOKEN

Status

The Status field MUST be a bitwise 'OR' of the following:

  • 0x1: DONE_MORE. This DONEINPROC message is not the final DONE/DONEPROC/DONEINPROC message in the response; more data streams are to follow.

  • 0x2: DONE_ERROR. An error occurred on the current SQL statement or execution of a stored procedure was interrupted. A preceding ERROR token SHOULD be sent when this bit is set.

  • 0x4: DONE_INXACT. A transaction is in progress.<46>

  • 0x10: DONE_COUNT. The DoneRowCount value is valid. This is used to distinguish between a valid value of 0 for DoneRowCount or just an initialized variable.

  • 0x100: DONE_SRVERROR. Used in place of DONE_ERROR when an error occurred on the current SQL statement that is severe enough to require the result set, if any, to be discarded.

CurCmd

The token of the current SQL statement. The token value is provided and controlled by the application layer, which utilizes TDS. The TDS layer does not evaluate the value.

DoneRowCount

The count of rows that were affected by the SQL statement. The value of DoneRowCount is valid if the value of Status includes DONE_COUNT.
