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

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::mysql->new();
Function: Builds a new Bio::DB::DBI::mysql object using the passed named
parameters.
Returns : an instance of Bio::DB::DBI::mysql
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("bioentry");
Function: This implementation uses standard MySQL only and hence cannot
implement this method. It will throw an exception if called.
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 table. The driver is not required to
honor the argument if present.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 will ignore 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.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
