US 2017/0286478 A1 · METHOD AND COMPUTING DEVICE FOR MODIFYING A QUERY THAT INCLUDES AT LEAST ONE TEMPORAL EXPRESSION

Abstract

A method, computer device and computer program product are provided to modify a query that includes at least one temporal expression to identify a point in time at which the query is to be reevaluated. In the context of a method, a modified query is constructed from the query that includes at least one temporal expression. The modified query also identifies a next point in time at which the result of the query is able to change. The method also executes the modified query to determine a result of the query and to also determine the next point in time at which the result of the query is able to change. The method further includes scheduling the modified query to again be executed at the next point in time at which the result of the query is able to change.

Dependent claims

A method for modifying a query that includes at least one temporal expression to identify a point in time at which the query is to be reevaluated, the method comprising:

constructing a modified query from the query that includes at least one temporal expression, wherein the modified query that is constructed is also configured to define a manner in which a next point in time at which the result of the query is able to change is to be identified;
executing, with processing circuitry, the modified query to determine a result of the query and to also determine the next point in time at which the result of the query is able to change;
and
scheduling the modified query to again be executed at the next point in time at which the result of the query is able to change.

1 more element

A computing device for modifying a query that includes at least one temporal expression to identify a point in time at which the query is to be reevaluated, the computing device comprising processing circuitry configured to:

construct a modified query from the query that includes at least one temporal expression, wherein the modified query that is constructed is also configured to define a manner in which a next point in time at which the result of the query is able to change is to be identified;
execute the modified query to determine a result of the query and to also determine the next point in time at which the result of the query is able to change;
and
schedule the modified query to again be executed at the next point in time at which the result of the query is able to change.

1 more element

A computer program product comprising at least one non-transitory computer-readable storage medium for modifying a query that includes at least one temporal expression to identify a point in time at which the query is to be reevaluated, the at least one non-transitory computer-readable storage medium storing computer-executable instructions configured, when executed, to cause an apparatus to:

construct a modified query from the query that includes at least one temporal expression, wherein the modified query that is constructed is also configured to define a manner in which a next point in time at which the result of the query is able to change is to be identified;
execute the modified query to determine a result of the query and to also determine the next point in time at which the result of the query is able to change;
and
schedule the modified query to again be executed at the next point in time at which the result of the query is able to change.
