/**
 * An object that represents a precompiled SQL statement.
 * <P>A SQL statement is precompiled and stored in a
 * {@code PreparedStatement} object. This object can then be used to
 * efficiently execute this statement multiple times.
 *
 * <P><B>Note:</B> The setter methods ({@code setShort}, {@code setString},
 * and so on) 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
 * {@code INTEGER}, then the method {@code setInt} should be used.
 *
 * <p>If arbitrary parameter type conversions are required, the method
 * {@code setObject} should be used with a target SQL type.
 * <P>
 * In the following example of setting a parameter, {@code con} represents
 * an active connection:
 * <pre>{@code
 *   BigDecimal sal = new BigDecimal("153833.00");
 *   PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES
 *                                     SET SALARY = ? WHERE ID = ?");
 *   pstmt.setBigDecimal(1, sal);
