Google BigQuery 表补丁/更新不起作用

Question

Google_Http_Request object {
  batchHeaders => array(3) (
    [Content-Type] => (string) application/http
    [Content-Transfer-Encoding] => (string) binary
    [MIME-Version] => (string) 1.0
  )

  )

  responseBody => null
  expectedClass => (string) Google_Service_Bigquery_Table
  accessKey => null
}

我有这个调用，它返回成功，但所需的更改没有反映在架构上。 tracking_prod_type 是一个新字段，它没有添加到架构中。我们尝试了Patch 和Update 方式，但我们无法添加额外的列。更新返回：Provided Schema does not match。补丁返回有效。

在 postBody 上，我们尝试了不同的语法，但都不起作用。 [etag] => (string) "wRHWmN_1J7FEq2j8vIkltiyoyRw/GVGxfUY15UK1iZLhzZzfWOf-1Ow"

我们尝试关注这个问答Bigquery add columns to table schema

当我们发出调用时，我们看到表架构上的 Last Modified 字段被修改，但结构没有新列。

更新

使用补丁更新2

这是当我有 tableResource 和 schema，并使用 PATCH 的时候。架构中列出的两个附加列。我得到了：Provided Schema does not match Table aerobic-forge-504:wr_dev.user_profile

Google_Http_Request object {
  batchHeaders => array(3) (
    [Content-Type] => (string) application/http
    [Content-Transfer-Encoding] => (string) binary
    [MIME-Version] => (string) 1.0
  )
  queryParams => array(0)
  requestMethod => (string) PATCH
  requestHeaders => array(3) (
    [content-type] => (string) application/json; charset=UTF-8
    [authorization] => (string) edited
    [accept-encoding] => (string) gzip
  )
  baseComponent => (string) https://www.googleapis.com

使用 PUT 更新3

当使用更新节点时，我仍然得到Provided Schema does not match Table aerobic-forge-504:wr_dev.user_profile

Google_Http_Request object {
  batchHeaders => array(3) (
    [Content-Type] => (string) application/http
    [Content-Transfer-Encoding] => (string) binary

  )
  queryParams => array(0)
  requestMethod => (string) PUT
  requestHeaders => array(4) (
    [content-type] => (string) application/json; charset=UTF-8
    [authorization] => (string) edited
    [accept-encoding] => (string) gzip
    [content-length] => (int) 1221

Answer 1

调用补丁或更新时，您需要提供一些看起来像表格的东西。在上面的示例中，您似乎没有传递表资源，而只是传递了表资源中的字段。您可能需要将您的 postBody 包装在 {"schema": {"fields": postBody } }

之类的东西中

与另一个问题相比，这有点令人困惑，因为 bq update 会为您进行包装。

您看到更新失败的原因是 bigquery 服务器根本看不到任何架构，因此它认为您正在尝试删除架构。而patch成功了但是什么都不做，因为它根本看不到任何有效的字段，所以它只是做了一个空的patch操作。

这是一个将字段添加到架构的 curl 会话示例。适应php应该比较容易。它使用来自here的auth.py

PROJECT_ID=<your_project_here>
DATASET_ID=scratch

BASE_URL=https://www.googleapis.com/bigquery/v2/projects
TABLES_URL=${BASE_URL}/${PROJECT_ID}/datasets/${DATASET_ID}/tables

### Make a scratch dataset.
bq --project_id=${PROJECT_ID} mk –d ${DATASET_ID}

SCHEMA="{'fields': [{'name':'foo', 'type': 'STRING'}]}"
TABLE_REF="{'tableId': 'table1', \
    'datasetId': 'scratch', \
    'projectId': '${PROJECT_ID}'}"

### Make a temporary table with a schema.
curl -H "$(python auth.py)" \
    -H "Content-Type: application/json" \
    -X POST \
    -d "{'tableReference': ${TABLE_REF}, \
         'schema': ${SCHEMA}}" \
    "${TABLES_URL}"

### Tables.update()
SCHEMA2="{'fields': [ \
    {'name':'foo', 'type': 'STRING'}, \
    {'name': 'bar', 'type': 'FLOAT'}]}"
TABLE_JSON="{'tableReference': ${TABLE_REF}, 'schema': ${SCHEMA2}}"
curl -H "$(python auth.py)" \
    -H "Content-Type: application/json" \
    -X PUT \
    -d "${TABLE_JSON}" \
    "${TABLES_URL}/table1"

### Tables.patch()
EXPIRATION_TIME=$(($(date +"%s")+24*60*60))000
curl -H "$(python auth.py)" \
    -H "Content-Type: application/json" \
    -X PATCH \
    --data-binary "{'expirationTime': '${EXPIRATION_TIME}'}" \
    "${TABLES_URL}/table1"
