Description

Conditional execution of query

This function evaluates a condition. Note that the values used in the then or else clause are evaluated lazily. They may be expressions that involve stored queries (i.e. queries stored using the LET keyword). These queries will not be evaluated if they are not needed.

This allows a query to cheaply branch. For example, if a parameter is given, then perform hash or upload to the server.
