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" + " )
