Unable to insert integer value into oracle database

I’m trying to insert integer value into oracle database but getting following error :
RemoteException wrapping System.Data.Odbc.OdbcException: ERROR [HY000] [Oracle][ODBC][Ora]ORA-00936: missing expression

I have performed below steps :

  1. read the data from excel and stored it in data table.
  2. opened the connection string
  3. converted variable to int 32 datatype and passing that argument into insert query. e.g. “insert into table_name (column_name) values (@argument_name)”
    Note : datatype of column_name in oracle database is NUMBER and datatype of argument is int 32.
