Name
Recordset.CacheSize Property — (Versions 2.0, 2.1, 2.5, 2.6)
Synopsis
recordset.CacheSize = cachesize
The CacheSize property indicates the number or records that are cached by ADO locally in system memory.
Datatype
Long
Description
The CacheSize property sets or reads the number of records that are kept in local memory at one time by ADO. The value of CacheSize must be at least 1, otherwise an error will occur. The default value of the CacheSize property is 1.
When a recordset is first opened, the number of records specified by the CacheSize property is gathered. After the record pointer moves beyond this number, another set of records is returned, the first being the next record in the recordset. If fewer records are available, the CacheSize requests only those records that are gathered.
The CacheSize property can be changed throughout the life of a recordset; however, the number of records retrieved into the cache does not change until the record pointer is moved outside the current cache.
The values within the cache do not reflect changes made by other users. To accomplish this, use the Resync method.
