[feat](case when) rewrite case when to compound predicate #56756

yujun777 · 2025-10-09T10:36:05Z

for a boolean data type case when expression, if all its when clauses' result are true / false literal, then can rewrite this case when to AND / OR expression.

for example:

case when a = 1 then true when b = 1 then false else c = 1 end   
rewrite to:  (a = 1) <=> true  or (not((b = 1) <=> true) and c = 1)

if (a = 1, true,  b = 1) 
rewrite to:  (a=1) <=> true or b = 1

then later, there are other rules will opt ' xxx <=> true', 'xxx = true'.

这个优化没有明显的优化点, 相反可能会降低效率. 因为在BE端我们对if 有很多优化,但 <=> 没有.

这个优化没有明显的优化点, 相反可能会降低效率. 因为在BE端我们对if 有很多优化,但 <=> 没有.

if (a = b, true, c = d) => a = b or c = d，这

for a boolean data type case when expression, if all its when clauses' result are true / false literal, then can rewrite this case when to AND / OR expression. for example: case when a = 1 then true when b = 1 then false else c = 1 end rewrite to: (a = 1) <=> true or (not((b = 1) <=> true) and c = 1) if (a = 1, true, b = 1) rewrite to: (a=1) <=> true or b = 1
