Description
Use the GET_OPERATION_TYPE
function to determine the operation type associated with a record. Knowing the operation type can be useful in a user exit. For example, the user exit can perform complex validations any time a delete is encountered. It also is important to know when a compressed record is being processed if the user exit is manipulating the full data record.
As an alternative, you can use the GET_RECORD_BUFFER
function to determine the operation type (see "GET_RECORD_BUFFER").
Syntax
#include "usrdecs.h" short result_code; record_def record; ERCALLBACK (GET_OPERATION_TYPE, &record, &result_code);
Buffer
typedef struct { char *table_name; char *buffer; long length; char before_after_ind; short io_type; short record_type; short transaction_ind; int64_t timestamp; exit_ts_str io_datetime; short mapped; short source_or_target; /* Version 2 CALLBACK_STRUCT_VERSION */ char requesting_before_after_ind; } record_def;
