我正在尝试使用补丁通过ruby Google API客户端更新现有表的架构。
以下是代码：
def updateTable(client, bq, schema,dataset,table)
result = client.execute(:api_method => bq.tables.patch,
:parameters => {'projectId' => PROJECT, 'datasetId' => dataset, 'tableId' => table},
:body_object => {
"tableReference" => {
"datasetId" => dataset,
"projectId" => "mydataset-1",
"tableId" => table
},
"schema" => schema
}
)
puts result.body
端
这是我得到的错误：
{
"error": {
"errors": [
{
"domain": "global",
"reason": "invalid",
"message": "Invalid schema update. Field a_b_testing_group is missing in new schema"
}
],
"code": 400,
"message": "Invalid schema update. Field a_b_testing_group is missing in new schema"
} }
我会感激任何指示和建议。 谢谢，
以下是示例模式：

BigQuery支持向现有表添加列，但不删除现有表。
为防止显示错误，在修补表架构时，始终在新架构中包含现有列，并仅向其添加列。
