## Detailed Description

is used to access data which is collected in a row.

## Member Function Documentation

## ◆ getArray()

com::sun::star::sdbc::XArray getArray | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets a SQL ARRAY value from the current row.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getBinaryStream()

com::sun::star::io::XInputStream getBinaryStream | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a stream of uninterpreted bytes.

The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARBINARY or LONGVARCHAR values.

Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a get method implicitly closes the stream. Also, a stream may return 0 when the method com::sun::star::io::XInputStream::available() is called whether there is data available or not.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getBlob()

com::sun::star::sdbc::XBlob getBlob | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets a BLOB (Binary Large OBject) value in the current row.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getBoolean()

boolean getBoolean | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as boolean.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getByte()

byte getByte | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a byte.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getBytes()

sequence< byte > getBytes | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a byte array.

The bytes represent the raw values returned by the driver.

Returns
  the column value; if the value is SQL NULL, the result is empty.

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getCharacterStream()

com::sun::star::io::XInputStream getCharacterStream | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a stream of uninterpreted bytes.

The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values.

Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a get method implicitly closes the stream. Also, a stream may return 0 when the method com::sun::star::io::XInputStream::available() is called whether there is data available or not.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getClob()

com::sun::star::sdbc::XClob getClob | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets a CLOB value in the current row of this `ResultSet` object.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getDate()

com::sun::star::util::Date getDate | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a date object.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getDouble()

double getDouble | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a double.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getFloat()

float getFloat | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a float.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getInt()

long getInt | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a long.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getLong()

hyper getLong | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a hyper.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getObject()

any getObject | ( | [in] com::sun::star::container::XNameAccess | typeMap | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

Returns
  the value of a column in the current row as an object. This method uses the given `Map` object for the custom mapping of the SQL structure or distinct type that is being retrieved.

Parameters

  typeMap | the type map is used to fetch the correct type

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getRef()

com::sun::star::sdbc::XRef getRef | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets a REF(<structured-type&gt) column value from the current row.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getShort()

short getShort | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a short.

Returns
  the column value

gets the value of a column in the current row as a String.

Returns
  the column value

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ getTime()

com::sun::star::util::Time getTime | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

gets the value of a column in the current row as a time object.

Returns
  the column value

gets the value of a column in the current row as a datetime object.

Returns
  the column value

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.

## ◆ wasNull()

boolean wasNull | ( |  | ) |
raises | ( | com::sun::star::sdbc::SQLException ) |  |  |

reports whether the last column read had a value of SQL NULL.

Note that you must first call getXXX on a column to try to read its value and then call `wasNull()` to see if the value read was SQL NULL.

Returns
  TRUE if so

Exceptions

  com::sun::star::sdbc::SQLException | if a database access error occurs.
