Hai every body,
I want to know how the--where condition--is executed in a sql query.
e.g., select aa,bb,cc from ttt where aa=100 and bb = 200 and cc =300.
my doubt is , will psql leave the record as on when it fails to satisfy a record having aa !=100
or will it chect for bb = 200 and cc = 300 also.
ie will it work like C-language if condition or not.
If i give paranthesis, will it change the execution plan accordingly.
Thanks in advance.
c u
