RecordCount Property (ADO)
Indicates the number of records in a Recordset object.
Returns a Long value that indicates the number of records in the Recordset.
Use the RecordCount property to find out how many records are in a Recordset object. The property returns -1 when ADO cannot determine the number of records or if the provider or cursor type does not support RecordCount. Reading the RecordCount property on a closed Recordset causes an error.
Bookmarks or approximate positioning
If the Recordset object does support either bookmarks or approximate positioning, this property returns the exact number of records in the Recordset. This property returns the exact number regardless of whether the Recordset has been fully populated.
In contrast, if the Recordset object does not support either bookmarks or approximate positioning, accessing this property might be a significant drain on resources. The drain occurs because all records must retrieved and counted to return an accurate RecordCount value.
- adBookmark related to bookmarks.
- adApproxPosition relates to approximate positioning.
In ADO versions 2.8 and earlier, the SQLOLEDB provider fetches all records when a server-side cursor is used, despite the fact that it returns True for both Supports (adApproxPosition) and Supports (adBookmark).
The cursor type of the Recordset object affects whether the number of records can be determined. The RecordCount property will return -1 for a forward-only cursor; the actual count for a static or keyset cursor; and either -1 or the actual count for a dynamic cursor, depending on the data source.
