The present invention relates to data manipulation language (DML) acceleration. Herein are database techniques to use value range analysis and range-limited execution operators when a value is excluded. In an embodiment, a computer receives a data access request that specifies an expression that includes operator(s), including a particular operator that has argument(s) that has only three possible values. Before detecting the actual value of a particular argument, the computer detects that a particular value of the three possible values is excluded for the particular argument. Responsively, an implementation of the particular operator that never accepts the particular value for the particular argument is selected. Applying the expression to fulfil the data access request entails invoking the selected implementation of the particular operator.
