// DocMerge from idl: service com::sun::star::sdbc::PreparedStatement
/** 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 
	 <member scope="com::sun::star::sdbc">XParameters::setInt()</member>
	 should be used. 
	 </P>
	 <p>
	 If arbitrary parameter type conversions are required, the method 
	 <member scope="com::sun::star::sdbc">XParameters::setObject()</member>
	 should be used with a target SQL type. 
	 </p>
	 <p>
	 Example of setting a parameter; <code>con</code> is an active connection. 
	 @example:StarBASIC 
	 <listing> 
	 pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?") 
	 pstmt.setDouble(1, 153833.00) 
	 pstmt.setLong(2, 110592) 
	 </listing> 
	 </p>
	 <P>
	 Only one 
	 <type scope="com::sun::star::sdbc">ResultSet</type>
	 per
	 <type scope="com::sun::star::sdbc">Statement</type>
	 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.
