regex - MySQL REGEXP Match / or End of Field -


i've got load of paths in mysql database (5.7.17-0ubuntu0.16.04.2) , user chooses selection of paths, want select paths , below, i've hit issue.

say user wants "/root/k" need select for:

a. /root/k% b. /root/k

how can regexp match end of field or / ?

i've tried following:

original query:

where path regexp ('/root/k/|/root/j/j/')  # works doesn't show items in path, ones below  path regexp '/root/k[/\z]' # same above path regexp '/root/k(?=/|$)'   # error 1139, repetition-operator invalid

i've tried: regex match _ or end of string gives error 1139

any other suggestions?

there no support lookarounds, not \z anchor in mysql regex. may use normal capturing group:

where path regexp '/root/k(/|$)'

it match

  • /root/k - literal char sequence
  • (/|$) - either / or end of entry.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

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...
