The ResultSet Variants<br />
Accessing databases is often a matter of critical speed. <strong>OpenOffice</strong>.<strong>org</strong> provides several ways of optimizing<br />
ResultSets and thereby controlling the speed of access. The more functions a ResultSet provides, the more<br />
complex its implementation usually is and therefore the slower the functions are.<br />
A simple ResultSet, provides the minimum scope of functions available. It only allows iteration to be applied<br />
forward, and for values to be interrogated. More extensive navigation options, such as the possibility of modifying<br />
values, are therefore not included.<br />
The Statement object used to create the ResultSet provides some properties which allow the functions of the<br />
ResultSet to be influenced:<br />
ResultSetConcurrency (const)<br />
specifications as to whether the data can be modified (specifications in accordance with<br />
com.sun.star.sdbc.ResultSetConcurrency).<br />
ResultSetType (const)<br />
specifications regarding type of ResultSets ( specifications in accordance with<br />
com.sun.star.sdbc.ResultSetType).<br />
The values defined in com.sun.star.sdbc.ResultSetConcurrency are:<br />
UPDATABLE<br />
READ_ONLY<br />
ResultSet permits values to be modified<br />
ResultSet does not permit modifications<br />
The com.sun.star.sdbc.ResultSetConcurrency group of constants provides the following specifications:<br />
