database - Month sequence number in a quarter -


i want determine month sequence number in quarter sql

i found code week:

select to_char( sysdate, 'yyyy-"q"q-"w"' )      || ( 7 + trunc( sysdate + 1, 'iw' ) - trunc( trunc( sysdate, 'q' ) + 1, 'iw' ) ) / 7          "current time" dual;

this give numeric value 1-3 representing month-within-the-quarter value:

select case mod(to_number(to_char(sysdate, 'mm')), 3)          when 0 3          when 1 1          when 2 2        end month_in_quarter   dual;

it uses modulus (mod) function value 0 - 2. converts 0 3 since want march, june, september, , december 3, not 0.

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
