Azure数据工厂表存储转换错误

Question

我正在尝试使用Azure数据工厂从Azure表存储中获取数据。我有一个名为orders的表，该表有30列。我只想从此表中获取3列（PartitionKey，RowKey和DeliveryDate）。 DeliveryDate列具有不同的数据类型，例如DateTime.Null（字符串值）和实际的datetime值。当我要预览数据时，出现以下错误：

数据源看起来像这样：

{
"name": "Orders",
"properties": {
    "linkedServiceName": {
        "referenceName": "AzureTableStorage",
        "type": "LinkedServiceReference"
    },
    "annotations": [],
    "type": "AzureTable",
    "structure": [
        {
            "name": "PartitionKey",
            "type": "String"
        },
        {
            "name": "RowKey",
            "type": "String"
        },
        {
            "name": "DeliveryDate",
            "type": "String"
        }
    ],
    "typeProperties": {
        "tableName": "Orders"
    }
},
"type": "Microsoft.DataFactory/factories/datasets"}

我测试了您的问题，它可以工作。您能告诉我更多有关此问题的详细信息还是我的测试有问题吗？

以下是我的测试数据：

数据集代码：

{
    "name": "Order",
    "properties": {
        "linkedServiceName": {
            "referenceName": "AzureTableStorage",
            "type": "LinkedServiceReference"
        },
        "annotations": [],
        "type": "AzureTable",
        "structure": [
            {
                "name": "PartitionKey",
                "type": "String"
            },
            {
                "name": "RowKey",
                "type": "String"
            },
            {
                "name": "DeliveryDate",
                "type": "String"
            }
        ],
        "typeProperties": {
            "tableName": "Table7"
        }
    },
    "type": "Microsoft.DataFactory/factories/datasets"
