Synopsis
You can use this function in conjunction with GET_datatype_ARG or GET_CALL_ARGS to determine information about the deferred RPCs in the queue. GET_ARG_TYPE returns a number corresponding to the argument’s datatype.
FUNCTION DBMS_DEFER_QUEUE.GET_ARG_TYPE
(callno IN NUMBER,
deferred_tran_db IN VARCHAR2,
arg_no IN NUMBER,
deferred_tran_id IN VARCHAR2)
RETURN NUMBER;The following table shows the mapping ofdatatypes to return values:
Argument Datatype | GET_ARG_TYPE Return Code |
|---|---|
BFILE (Oracle8 only) | 114 |
BLOB (Oracle8 only) | 113 |
CFIL (Oracle8 only) | 115 |
CHAR | 96 |
CLOB (Oracle8 only) | 112 |
DATE | 12 |
NUMBER | 2 |
RAW | 23 |

There are no restrictions on calling GET_ARG_TYPE.
