Default Value

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getRecordFieldIndex([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setRecordFieldIndex([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property contains the index of the selected property of the current record. RecordFieldIndex valid values are from 0 to (RecordFieldCount - 1).

After a successful query, the property values for each record will be provided in the Records properties.

To retrieve a particular property value for a record, first set RecordFieldIndex to a valid response property index, and then query records collection for the value of that property.

The size of the array is controlled by the RecordCount property.

This property is not available at design time.
