在流水线运行期间,我得到了以下错误。
Operation on target ac_ApplyMapping failed: Column name or path 'StudentId'
duplicated in 'source' under 'mappings'. Please check it in 'mappings'.在复制活动中,我们应用了以下映射。
{
"type": "TabularTranslator",
"mappings": [{
"source": {
"name": "StudentId",
"type": "string"
},
"sink": {
"name": "StudentId_Primary",
"type": "string"
}
}, {
"source": {
"name": "StudentId",
"type": "string"
},
"sink": {
"name": "StudentId_Secondary",
"type": "string"
}
}
]
}有没有办法处理这种情况?

可以使用Derived column转换更改源中的列名,然后映射到接收器。
