Closes #5023
This PR implements
hasSideEffects
forGpuSequence
to fix a bug where a conditional expression such asCASE .. WHEN
could result inGpuSequence
throwing an exception because we were evaluating for all rows and not just the rows that met the condition.I filed a follow on issue #5041 to do the same for all other expressions that could potentially have side-effects.
