+/** represents a precompiled SQL statement.
+ <P>
+ A SQL statement is pre-compiled and stored in a PreparedStatement object.
+ This object can then be used to efficiently execute this statement multiple
+ times.
+ </P>
+ <P>
+ <B>
+ Note:
+ </B>
+ The
+ <code>setXXX</code>
+ methods for setting IN parameter values
+ must specify types that are compatible with the defined SQL type of
+ the input parameter. For instance, if the IN parameter has SQL type
+ Integer, then the method
+ com::sun::star::sdbc::XParameters::setInt()
+ should be used.
+ </P>
+ <p>
+ If arbitrary parameter type conversions are required, the method
+ com::sun::star::sdbc::XParameters::setObject()
+ should be used with a target SQL type.
+ </p>
+ <p>
+ Example of setting a parameter; <code>con</code> is an active connection.
+ @code{.bas}
+ pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?")
+ pstmt.setDouble(1, 153833.00)
+ pstmt.setLong(2, 110592)
+ @endcode
+ </p>
+ <P>
+ Only one
+ com::sun::star::sdbc::ResultSet
+ per
+ com::sun::star::sdbc::Statement
+ can be open at any point in
+ time. Therefore, if the reading of one ResultSet is interleaved
+ with the reading of another, each must have been generated by
+ different Statements. All statement
+ <code>execute</code>
+ methods implicitly close a statement's current ResultSet if an open one exists.
