SET OPTIMIZE Change the setting that determines whether to optimize using the open orders when processing a filtered database file ------------------------------------------------------------------------------ Syntax SET OPTIMIZE ON | OFF | (<lToggle>) Arguments ON enables optimization. OFF disables optimization. <lToggle> is a logical expression that must be enclosed in parentheses. A value of true (.T.) is the same as ON, and a value of false (.F.) is the same as OFF. Note: The initial default of this setting depends on the RDD. Description For RDDs that support optimization, such as DBFCDX, SET OPTIMIZE determines whether to optimize filters based on the orders open in the current work area. If this flag is ON, the RDD will optimize the search for records that meet the filter condition to the fullest extent possible, minimizing the need to read the actual data from the database file. If this flag is OFF, the RDD will not optimize. Examples . The following example enables optimization for the Inventor database file using the SET OPTIMIZE command: USE Inventor NEW VIA "DBFCDX" SET OPTIMIZE ON Files Library is CLIPPER.LIB.
