Function

a!queryRecordType_20r4( recordType, selection, filters, pagingInfo, fetchTotalCount )

Executes a query on a given record type and returns the result. This is an older version of the a!queryRecordType() function, which has new functionality.

Parameters

Returns

The return type of a!queryRecordType will be a Map data type with the following parameters:

• success (Boolean)
• data (List of Record Maps)
• startIndex (Integer)
• batchSize (Integer)
• sort (List of SortInfo)
• totalCount (Integer)
• identifiers (List of Integer or List of Text)
• errorCode (Text)

This map will have the same named fields as a DataSubset (so that it can seamlessly be cast to that type when being passed around your application) with the addition of "success" and "errorCode" fields, like results from an Integration object, so app developers can build error-handling into their applications.

Error Codes

a!queryRecordType returns a query result even if a runtime error happened. In these cases the "success" field of the result would have a value of false and the "errorCode" field will return an Appian Error Code indicating what has happened. You can use these codes to decide what to do next in your application.

Usage considerations

• Expression-backed record types are not supported.
• The batchSize in your pagingInfo for a!queryRecordType cannot be larger than 5000, and cannot be -1.
• If you don't specify a selection of fields, all fields are returned.
• Multiple sortInfos is not yet available for process-backed record types.
• If the record type isn't sorted by the identifier, a final identifier sort is added to ensure deterministic sorting.
• The data in the query returned is a list of records, not dictionary.
• This query does not yet support aggregation.
• You must update the target record type after upgrading to 20.3 in order to use this query.
