Returned message format
Two optional keys, RETURN_TCL
and
RETURN_SCHEMA
, are added as sub-keys of OB_ACTION
to
indicate the returned result set format:
Key name: RETURN_TCL
Range: 0 or 1 (0: not Tcl list, 1:Tcl list)
Default: 0
Key name: RETURN_SCHEMA
Range: empty or a DB SCHEMA name
Default: empty
- If
RETURN_TCL
is set, then the result set is made as a Tcl list. This is for compatibility for old behavior. - If
RETURN_SCHEMA
is empty, then the engine generates the return message based on the result set metadata. - If
RETURN_SCHEMA
is set a schema name, then the engine generates the return message based on the given schema. - If both
RETURN_TCL
andRETURN_SCHEMA
are set, then the engine converts the return message to a Tcl list. The column order is based on the give schema.
