在ibatis中调用MySQL的函数，函数的参数类型是字符串，参数是iterate遍历list的结果

select distinct(depId), depName, parentId, fullPath, dbCode, memo, nodeOrder, customId
from depTree WHERE FIND_IN_SET(depId,queryDeptreeParentnodeInfo

#list[]#

)

函数正常是这样的queryDeptreeParentnodeInfo('1,2,3')
但是iterate的结果不是一个字符串，怎样才能实现该效果

select distinct(depId), depName, parentId, fullPath, dbCode, memo, nodeOrder, customId
from depTree WHERE FIND_IN_SET(depId,queryDeptreeParentnodeInfo

#list[]#

)

是这样的
