ARDBCSetEntry

Description

This function modifies the contents of a single entry or BLOB. The plug-in server calls this function when:

The BMC Remedy AR System server receives a call to ARSetEntry or ARMergeEntry from the client.
Users enter information to create or merge entries into an external form.
A Push Fields filter or an escalation action modifies an entry.

If the specified entry does not exist, the plug-in creates it. An ARDBCSetEntry operation on a nonexistent entry can occur when the BMC Remedy AR System server receives a call to ARMergeEntry from a client.

Important

If you do not define this function, the BMC Remedy AR System server receives an error message and the entry is not modified.

Synopsis

#include "ardbc.h"

int ARDBCSetEntry(
  void *object,
  char *tableName,
  ARVendorFieldList *vendorFieldList,
  ARInternalId transId,
  AREntryIdList *entryId,
  ARFieldValueList *fieldValueList,
  ARTimestamp getTimestamp,
  ARStatusList *status)

Input arguments

object

Pointer to the plug-in instance that the call to ARPluginCreateInstance returned.

tableName

Name of the external table on which the plug-in sets this entry.

vendorFieldList

List of external form fields.

The plug-in uses this list to map BMC Remedy AR System field identification numbers (field IDs) to corresponding external form field names. All other input arguments and return values must see the BMC Remedy AR System field IDs.

transId

Transaction identification number (transaction ID) that the plug-in server designates for each transaction. The transaction ID is unique to the thread that the BMC Remedy AR System server uses to access the ARDBC plug-in. There is only one open transaction per server thread.

entryId

Unique identifier for the entry to set. This must correspond to a value in the external data source and must be unique, non-NULL, and either character or numeric data. For an external data source, the entry ID can be longer than 15 characters. Therefore, the entry ID can consist of one or more values of type AREntryIdType and is represented by the AREntryIdList structure.

fieldValueList

List of the data in a new entry. The list consists of one or more field and value pairs that the server specifies in any order.

getTimestamp

Time stamp that specifies when the client last retrieved the entry. The ARDBC plug-in can provide functionality like that provided by the BMC Remedy AR System server by returning an error if an entry was modified (presumably by another client) after the calling client last retrieved it. For example, the plug-in can store a modification time stamp and compare this value with it to determine whether the entry changed since the last retrieval. If the value of this parameter is 0, ignore it.

Return values

status

List of zero or more notes, warnings, or errors generated from a call to this function. For a description of all possible values, see Error-checking.
