tsql - SQL where clause with one parameter to check either int or string field -


i have stored procedure:

alter procedure [dbo].[getclassinfo](@classid int) begin     select [usergroupid]       ,[gname]         ,[accesscode]   [dbo].[usergroup]   usergroupid = @classid or accesscode = @classid end

now, want parameter i'm sending check either usergroupid number or accesscode string.

which solution painless check both cases using 1 parameter?

you can't have none integer values in parameter have changed varchar.

alter procedure [dbo].[getclassinfo] ( @classid varchar(50) )     begin         if isnumeric(@classid + '.0e0') = 1             begin                 declare @classidint int = convert(int , @classid);                  select  [usergroupid]                       , [gname]                       , [accesscode]                    [dbo].[usergroup]                   @classidint = [usergroupid];             end;          if isnumeric(@classid + '.0e0') = 0             begin                 select  [usergroupid]                       , [gname]                       , [accesscode]                    [dbo].[usergroup]                   [accesscode] = @classid;             end;     end;

the if statement determines if value passed integer , runs appropriate query
