Database Access 205
""Customer""")
If Not IsNull(ResultSet) Then
While ResultSet.next
MsgBox ResultSet.getString(1)
Wend
End If
Once the database connection has been established, the code used in the example first uses
the Connection.createObject call to create a Statement object. This Statement object then
uses the executeQuery call to return the actual ResultSet. The program now checks
whether the ResultSet actually exists and traverses the data records using a loop. The
values required (in the example, those from the CustomerNumber field) returns the
ResultSet using the getString method, whereby the parameter 1 determines that the call
relates to the values of the first column.
The ResultSet object from SDBC is comparable with the Recordset object from DAO and ADO, since
this also provides iterative access to a database.
The database is actually accessed in OpenOffice.org through a ResultSet object. This reflects the
content of a table or the result of a SQL-SELECT command. In the past, the ResultSet object provided
the resident methods in the Application object for navigation within the data, for example,
DataNextRecord ).
Type- Specific Methods for Retrieving Values
As can be seen in the example from the previous section, OpenOffice.org provides a
getString method for accessing table contents. The method provides the result in the form
of a string. The following get methods are available:
getByte()
supports the SQL data types for numbers, characters and strings
getShort()
getInt()
supports the SQL data types for numbers, characters and strings
supports the SQL data types for numbers, characters and strings
getLong()
supports the SQL data types for numbers, characters and strings
getFloat()
supports the SQL data types for numbers, characters and strings
getDouble()
supports the SQL data types for numbers, characters and strings
getBoolean()
supports the SQL data types for numbers, characters and strings
getString()
