本文介绍了一种使用特定元素迭代属性列表的方法，通过配置不同的参数如prepend、property、open等，可以生成复杂的SQL条件语句。重点在于如何正确设置这些参数以实现所需的SQL输出。

 Iterate Attributes:
prepend – the overridable SQL part that will be prepended to the statement (optional)
property – a property of type IList that is to be iterated over (required)
open – the string with which to open the entire block of iterations, useful for brackets (optional)
close – the string with which to close the entire block of iterations, useful for brackets (optional)
conjunction – the string to be applied in between each iteration, useful for AND and OR (optional)
Table 3.10. Creating a list of conditional clauses
Element	Description


<iterate>	Iterates over a property that is of type IList Example Usage:
<iterate prepend="AND" property="UserNameList"
  open="(" close=")" conjunction="OR">
  username=#UserNameList[]#
</iterate>
Note: It is very important to include the square brackets[] at the end of the List property name when using the Iterate element. These brackets distinguish this object as an List to keep the parser from simply outputting the List as a string.
