ARGetEntry

Note

You can continue to use C APIs to customize your application, but C APIs are not enhanced to support new capabilities provided by Java APIs and REST APIs.

Description

Retrieves the form entry with the indicated ID from the specified server. You can retrieve data for specific fields, all (accessible) fields, or no fields (which is useful to verify whether a form has any entries). This function returns only the name, size, and compressed size of attachment fields. Use ARGetEntryBLOB to retrieve the contents of the attachment.

Privileges

The system returns data based on the access privileges of the user that you specify for the control parameter. User permissions are verified for each specified field. The system returns values for accessible fields and warning messages for fields the user cannot access.

Synopsis

#include "ar.h"
#include "arerrno.h"

#include "arstruct.h"

int ARGetEntry(
   ARControlStruct *control,
   ARNameType schema,
   AREntryIdList *entryId,
   ARInternalIdList *idList,
   ARFieldValueList *fieldList,
   ARStatusList *status)

Input arguments

control

The control record for the operation. It contains information about the user requesting the operation, where that operation is to be performed, and which session is used to perform it. The user and server fields are required.

schema

The name of the form containing the entry to retrieve.

entryId

The ID of the entry to retrieve.

Note

The system identifies entries in join forms by concatenating the entry IDs from the member forms. As a result, an entry ID can consist of one or more values of type AREntryIdType and, therefore, is represented by the AREntryIdList structure.

idList

A list of zero or more internal IDs that specify the fields to retrieve. Specify NULL for this parameter (or zero fields) to retrieve all (accessible) fields. Specify NULL for both this parameter and the fieldList parameter if you do not want to retrieve any fields. To minimize network traffic, specify only the fields that you need if you do not require the data for all fields. If an attachment field is specified in the list, only its name, size, and compressed size are returned. Use ARGetEntryBLOB to retrieve the contents of the attachment.

Return values

fieldList

A list of zero or more field/value pairs that identifies the data for the specified entry. The fields are returned in the order specified by idList. If the user does not have permission for a specified field or the field does not exist, the system does not return a value for the field/value pair. Specify NULL for this parameter if you do not want to retrieve any field data.

status

A 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.
