sql server - SQL Statement not retrieving any results -


i seem have hit hole in road code (again) doesn't seem working: sort-of follow previous question regarding sql inner joining. (you can view here how can retrieve data sql statement based on 2 table's criteria)

so trying retrieve data (name(s) of drivers) based on criteria after executing sql statement seems no results.

here sql statement:

sqlcommand test = new sqlcommand( "select[dp_name] from[driverprofile] dp  inner join driverprofilesettings dps on dps.dps_dp_fk = dp.dp_pk  dps.[dps_routeallocation] in  ( '  " + "8" + " '  )",con);

in database:

  • driverprofile table contains name (dp_name)
  • driverprofilesettingscontains routes driver allowed drive in (dps_routeallocation), set values "8" (without quotes) in order test sql statement.
  • driverprofilesettings contains primary key (dps_dp_fk) of driverprofile.

note:

  • i have tried removing single quotes ( ' ') , on statement still doesn't show results.
  • i coding in c# (using visual studio)

any appreciated!

you have spaces around 8. try changing ( '" + "8" + "' ), or if dps_routeallocation numeric field, remove single quotes ( " + "8" + " )

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...
