Factor that are to be considered in writing the conditional expression: It is recommended to use simple column or literal as operands in a conditional expression. Numeric comparisons are made faster when compared with the characters, date and null characters. Equality expression will be processed in a faster rate when compared with inequality expressions. Use literals in place of the conditional expressions. Specify False condition first when multiple AND condition is used. Specify True condition first when multiple OR condition is used. Usage of NOT logical operation is avoided.
