Syntax
public bool GetRecords( string SQLFilter, int TopRows, int PageNumber, string SQLOrder, Action<TheStorageMirror<(Of <(<'T>)>)>..::..StoreResponse> pCallBack, bool LocalCallBackOnly, bool InitIfNotInit )
Parameters
- SQLFilter
- Type: String
The "WHERE" clause to filter the records returned. Generally the filter should consist of the form [PropertyName] [Operation] [Value], e.g. FriendlyName = "MyThing"
- TopRows
- Type: Int32
The maximum number of records to return from the query
- PageNumber
- Type: Int32
The page number for the query, if the IStorageService supports a paging mechanism. Note that this is only used for retrieval from the IStorageService and not the MirrorCache.
- SQLOrder
- Type: String
The "ORDER BY" clause to order the records returned. Generally the string should consist of the form [PropertyName] [desc | asc], e.g. cdeCTIM desc
- pCallBack
- Type: Action<(Of <(<'TheStorageMirror<(Of <(<'T>)>)>..::..StoreResponse>)>)>
The callback method that will be invoked upon error or completed retrieval of records.
- LocalCallBackOnly
- Type: Boolean
If set to true, no request is sent to a remote StorageService.
- InitIfNotInit
- Type: Boolean
If the StorageMirror is not ready yet and this value is true, InitializeStore will be called before proceeding with the request.
