plsql - Can Oracle PL/SQL support short-circuit evaluation? -

-

given v_ssn_ind integer := if trim(p_ssn) null 0 else 1 end if;

i know can this: if v_ssn_ind=1 then…

but can short-circuit evaluation, ie: if v_ssn_ind then… ?

first off, talking not appear have short-circuit evaluation. short-circuit evaluation when code like

if( quick_condition , slow_condition )   <<do something>> end if;

evaluates second slow condition if , if initial quick condition evaluates true.

second, assignment of value v_ssn_ind not syntactically valid.

third, no, cannot say

if <<integer variable>>

because not make sense. value evaluate true , value evaluate false? if 0 false , 1 true, example, 17 translate to?

if declaring sort of indicator variable, make sense use boolean data type rather integer. if use boolean, can 

if <<boolean variable>>

because eliminates ambiguity. won't faster adding = true if condition however.
