DBIx::DataModel::Statement::JDBC(3)

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 NX 1;
  $statement->relative(15);      # move down 15 records
  my $row_16 = $statement->next; # record NX 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.
