i have comma separated string need convert in order use in sql in statement e.g select * table filedvalue in(conversion)

below method have come far. value being passed parameter parameter gbl075,gbl008

public string paramconverter(string parameter)     {         string conversion="";          string newstring="";           string[] parts = parameter.split(",");              for(string part : parts)             {                                 newstring = newstring.concat("'"+part+"',");             }                conversion = new stringbuilder().append(newstring).tostring();             int ind = conversion.lastindexof(",");             conversion = new stringbuilder(conversion).delete(ind,ind+1).tostring();             system.out.println(conversion);            return conversion;      }

however when read console output below results variable conversion

'gbl075','gbl008' 'gbl075','gbl008'

this not work in sql statement. need correct method , need assistance. thanks.

in java 8 added stringjoiner class:

stringjoiner joiner = new stringjoiner(", "); joiner.add("foo"); joiner.add("bar"); joiner.add("baz"); string joined = joiner.tostring(); // "foo, bar, baz"

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
