Number of Records Buffered property<br />

Description<br />

Specifies the minimum number of records buffered in memory during a query in the block.<br />

Applies to block<br />

Set <strong>Form</strong> <strong>Builder</strong><br />

Default<br />

NULL; which indicates the minimum setting allowed (the value set for the Number of Records Displayed<br />

property plus a constant of 3).<br />

Required/Optional optional<br />

Usage Notes<br />

• <strong>Form</strong> <strong>Builder</strong> buffers any additional records beyond the maximum to a temporary file on disk.<br />

• Improve processing speed by increasing the number of records buffered.<br />

• Save memory by decreasing the number of records buffered. This can, however, result in slower<br />

disk I/O.<br />

• If you anticipate that the block may contain a large number of records either as the result of a query<br />

or of heavy data entry, consider raising the Number of Records Buffered property to increase<br />

performance.<br />

• Consider lowering the Number of Records Buffered property if you anticipate retrieving large items,<br />

such as image items, because of the amount of memory each item buffered may require.<br />

Number of Records Buffered restrictions<br />

• If you specify a number lower than the minimum, <strong>Form</strong> <strong>Builder</strong> returns an error when you attempt to<br />

accept the value.<br />
