NAME

DBIx::DataModel::Statement::JDBC - Statement for interacting with DBD::JDBC

SYNOPSIS

When defining the DBIx::DataModel Schema :

  DBIx::DataModel->Schema("MySchema",
     statementClass => "DBIx::DataModel::Statement::JDBC"
  );

When using the schema:

  my $statement = $source->select(...,
                                  -resultAs => 'statement');

  my $n_rows = $statement->size; # size of result set
  my $row_1 = $statement->next;  # record N° 1;
  $statement->relative(15);      # move down 15 records 
  my $row_16 = $statement->next; # record N° 16
  $statement->beforeFirst;       # back to beginning of result set

DESCRIPTION

Scrollable statement for DBD::JDBC datasources. Provides an interface layer to some JDBC methods on Java ResultSet and Statement objects.

METHODS

Calls to the following Java methods are encapsulated in the statement class. See the JDBC javadoc for details:

getMemberCount

number of members in the resultset.

size

current number of rows in the resultset (may be smaller than memberCount if the resultset was restricted through setMaxRows).

getSQLStatement

getRow

index of the current record in the resultset.

beforeFirst

afterLast

isBeforeFirst

isAfterLast

relative

  $statement->relative($delta)

Move the statement $delta rows from the current position ($delta may be positive or negative).

absolute

  $statement->absolute($row_index)

Move the statement at position $row_index.

setMaxRows

  $statement->setMaxRows($max)

Limits the number of rows in ResultSet. Further rows are silently ignored.
