Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

new

Title   : new
Usage   : my $obj = Bio::DB::DBI::Oracle->new();
Function: Builds a new Bio::DB::DBI::Oracle object using the passed named 
          parameters.
Returns : an instance of Bio::DB::DBI::Oracle
Args    : named parameters with tags -dbcontext (a Bio::DB::DBContextI
          implementing object) and -sequence_name (the name of the sequence
          for PK generation)

next_id_value

Title   : next_id_value
Usage   : $pk = $obj->next_id_value();
Function: 
Example :
Returns : a value suitable for use as a primary key
Args    : The database connection handle to use for retrieving the
          next primary key value.

          Optionally, the name of the primary key generating
          sequence. If omitted, the value returned by sequence_name()
          will be used.

last_id_value

Title   : last_id_value
Usage   :
Function: Returns the last unique primary key value
          allocated. Depending on the argument and the driver, the
          value may be specific to a table, or independent of the
          table.

          This implementation does not need to know the table.
Example :
Returns : a value suitable for use as a primary key
Args    : The database connection handle to use for retrieving the primary
          key from the last insert.

          Optionally, the name of the primary key generating
          sequence. If omitted, the value returned by sequence_name()
          will be used.

ifnull_sqlfunc

Title   : nvl_sqlfunc
Usage   :
Function: Get the name of the SQL function that takes two arguments
          and returns the first if it is not null, and the second
          otherwise.

          Most RDBMSs will have such a function, but unfortunately
          the naming is different between them. E.g., in MySQL the
          name is IFNULL(), whereas in Oracle it is NVL().

Example :
Returns : the name of the function as a string, without parentheses
Args    : none

build_dsn

Title   : build_dsn
Usage   :
Function: Constructs the DSN string from the DBContextI object. Since this
          may be driver-specific, specific implementations may need to
          override this method.
Example :
Returns : a string (the DSN)
Args    : a Bio::DB::DBContextI implementing object
