3.9.4. Iterate Element
This tag will iterate over a collection and repeat the body content for each item in a List
| 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. |
<iterate prepend=" "
open="(" close=")" conjunction=" OR ">
consultation_doctor_team_member_id = #[].consultation_doctor_team_member_id#
and permission_id = #[].permission_id#
</iterate>
1、prepend：前缀的意思
2、open="(" close=")" 使用括号括起来的意思
3、conjunction ：表示用or 填充
4、consultation_doctor_team_member_id = #[].consultation_doctor_team_member_id#
and permission_id = #[].permission_id# 下边是循环体
##表示变量，[]表示数据索引，类似于C#代码中[i]

特此声明，iBatis.net没有foreach，查边官方文档，没有这个api或标签。java版本的有！
sql 监视语句：
EXEC sp_executesql N'SELECT * FROM dbo.t_c_team_member_permission where ( consultation_doctor_team_member_id = @param0 and permission_id = @param1 OR consultation_doctor_team_member_id = @param2 and permission_id = @param3 )',
N'@param0 nvarchar(16),@param1 nvarchar(1),@param2 nvarchar(16),@param3 nvarchar(1)',
@param0 = N'CONDTM0000000033', @param1 = N'1',
@param2 = N'CONDTM0000000032', @param3 = N'1'
