组合多个计算字段时遇到问题......
表格(简体)
$('.infor-experience').on('click', '.submit', function(e) {
alert("TEST");
})
目标是构建一个包含4个平均值计算列的报告(为清晰起见显示的标签,目前与查询标题不匹配:
tblHVSR
+--------+-------------+--------------+-------------------+-----------------------------+
| hvsrID | hvsrChildID | hvsrParentID | hvsrDateOfContact | hvsrDaysParentReadWithChild |
+--------+-------------+--------------+-------------------+-----------------------------+
| autoIn | smallint | smallint | date | smallint |
+--------+-------------+--------------+-------------------+-----------------------------+
经过大量的网络搜索后,我尝试了以下内容:
+-------+--------+-----------+-----------+-----------+----------+
| Child | Parent | 1MonthAvg | 3MonthAvg | 6MonthAvg | 1YearAvg |
+-------+--------+-----------+-----------+-----------+----------+
显然,我迷失在这里,而且情况只会越来越糟。有人可以帮我解决这个问题吗?
