sql 服务器中单列中多列的逗号分隔值

Question

我有一个 table 包含三列 Id、Errorcode、ErrorDescription，其中 errorcode 和 errordescription 列中有逗号分隔值

这里我需要连接第2列和第3列的值，例如第2列的第一个值-第3列的第一个值等等用逗号（，）分隔

示例：实际 Table

Id	Errorcode	ErrorDescription
1	204,201,33	Invalid Object,Out Of Range,Invalid Format
2	21,44	FileInvalid,Invalid date
3	20	Invalid parse

所需输出：

Id	Error
1	204-Invalid Object, 201-Out Of Range, 33-Invalid Format
2	21-FileInvalid, 44-Invalid date
3	20-Invalid parse
