mysql - escap character make date value null -


when use - in date format, works fine. however, returns null if used /

select str_to_date(concat('2017-04-02',' ', sec_to_time('45000')),'%y/%m/%d %h:%i:00 %p') cities;

you can try this:

select date_format(str_to_date(concat('2017-04-02',' ', sec_to_time('45000')),'%y-%m-%d %h:%i:00'), '%y/%m/%d %h:%i:00 %p') cities;

you have apply format mask string before change date format. don't have either or pm in original string, have remove %p.

a similar case here: updating date format in mysql

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...
