mysql - C# SQL : update with params - getting 0 and without the text -


i making databasemanager class solution , getting number 0 when trying update text. example : have name michael , wanted change "michael , mike" i'll use update.

public void addcrime(csteamid id, string crime, string time) {     try     {         mysqlconnection connection = createconnection();         mysqlcommand command = connection.createcommand();         crime = "," + crime;         command.commandtext = "update `" + main.instance.configuration.instance.databasetablename           + "` set `crime` = crime + ( @crime ) `steamid` = @steamid; select `crime` `"           + main.instance.configuration.instance.databasetablename           + "` `steamid` = @steamid";         command.parameters.addwithvalue("@steamid", id);         command.parameters.addwithvalue("@crime", crime);         connection.open();         command.executenonquery();         connection.close();         addtime(id, time);     }     catch (exception ex) { logger.log(ex); } }

how call : 

databasemanager.addwanted(player.csteamid, command[1], command[2]);

thanks everyone!

yor last sentence in command select statement, nonquery not return values, number of rows affected. change executescalar , store value of select in variable.

second error data type of parameter @steamid. set value id, declares csteamid id... cstreamid not string, change addwithvalue

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...
