-
将
flights.csv文件中的数据导入flights表：cbt import flights flights.csv
在 Bigtable Studio 中，运行以下查询以验证表是否已填充：
-
SELECT * FROM airports LIMIT 10;
-
SELECT * FROM flights LIMIT 10;
-
在 Bigtable Studio 中创建上下文集
在本部分中，您将创建一个名为 flights-assistant 的上下文集。此上下文集不包含任何上传到其中的上下文集文件。
在 Google Cloud 控制台中，前往 Bigtable 页面。
从列表中选择一个实例。
在导航菜单中，点击 Bigtable Studio。
在探索器窗格中，点击上下文集旁边的查看操作 ()。
点击创建上下文集。
在上下文集名称中，输入
flights-assistant。点击创建。
在 Studio 中测试 QueryData
在本部分中，通过提出自然语言问题来使用 flights-assistant 设置的上下文，以生成 SQL 查询。
由于上下文集未上传任何上下文集文件，并且 Bigtable 架构仅公开列族名称 (info)，而不公开单个列限定符，因此 QueryData 会猜测列限定符并生成次优查询。
- 在探索器窗格中，点击上下文集旁边的查看操作 ()。
- 点击测试上下文集。
- 在查询编辑器中，点击使用 QueryData 生成 SQL，所用模型：flights-assistant。
输入以下自然语言问题以生成 SQL 查询，然后点击生成。
Find flights from SFO to JFK.查看 SQL 查询。在未设置上下文的情况下，QueryData 会看到 flights 表上的 info 列族 (
MAP<BYTES, BYTES>)，但看不到列限定符departure_airport和arrival_airport，因此它会猜测限定符名称，例如origin和destination：SELECT _key, info FROM flights WHERE CAST(info['origin'] AS STRING) = 'SFO' AND CAST(info['destination'] AS STRING) = 'JFK';在使用 QueryData 代理上下文“flights-assistant”生成 SQL 窗口中，点击修改。
输入以下自然语言问题以生成 SQL 查询，然后点击更新。
Tell me flights that can help me beat nighttime traffic if traveling from New York数据库无法理解术语
nighttime traffic，并猜测flights表中不存在的列限定符，如以下查询所示。-- Assuming 'nighttime traffic' refers to flights departing during the night, -- defined here as between 8:00 PM (20:00) and 5:00 AM (05:00). SELECT CAST(_key AS STRING) AS flight_id, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['origin'] AS STRING) AS origin, CAST(info['destination'] AS STRING) AS destination, CAST(info['departure_time'] AS STRING) AS departure_time FROM flights WHERE CAST(info['origin'] AS STRING) = 'New York' AND ( EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 20 OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 5 );在使用 QueryData 代理上下文“flights-assistant”生成 SQL 窗口中，点击修改。
输入以下自然语言问题以生成 SQL 查询，然后点击更新。
Show me flights to Raleigh-Durham如果没有值搜索上下文，QueryData 会猜测列限定符并过滤
Raleigh-Durham。由于flights表将城市存储为info['arrival_city']下的Raleigh-durham，因此该查询不会返回任何行。SELECT _key, info FROM flights WHERE CAST(info['destination_city'] AS STRING) = 'Raleigh-Durham';
为上下文集生成上下文
在本部分中，您将准备环境并创建一个上下文文件，以帮助提高上下文集的查询功能。
设置环境
您必须先准备好环境，然后才能开始生成上下文。
如需设置您的环境，请执行以下步骤：
- 安装 Antigravity CLI。如需了解详情，请参阅 Antigravity CLI 使用入门。
- 安装 Google Cloud CLI。
设置应用默认凭据 (ADC)。在终端中运行以下命令，以进行身份验证并选择项目：
gcloud auth application-default login安装
uv，这是一个 Python 软件包和项目管理器，是上下文工程智能体的前提条件。如果您的系统上尚未安装 Python，uv可以为您安装。-
agy plugin install https://github.com/GoogleCloudPlatform/db-context-enrichment/tree/main/plugin 在终端中，启动 Antigravity CLI。
agy使用 MCP Toolbox 设置数据库连接，以便生成上下文。连接在
tools.yaml配置文件中定义。如需在当前目录中创建
tools.yaml配置文件，请输入如下提示：Help me set up a database connection.按照技能提供的说明操作。如需详细了解
tools.yaml文件，请参阅 MCP Toolbox 文档。如需在创建
tools.yaml文件后重新加载配置，请在 Antigravity CLI 中运行以下命令，并按照说明重新加载 Toolbox MCP 服务器：/mcp选择
db-context-engineering_toolbox。选择
Restart。
验证 MCP Toolbox 和上下文工程智能体插件是否已连接并可供使用。
/mcp
生成模板上下文
在上一部分中，QueryData 不知道 flights 列限定符或术语 nighttime
traffic。在本部分中，为了解决此问题，您需要在上下文集文件中定义模板，将自然语言问题映射到 info 列族限定符，并将 nighttime traffic 定义为下午 5:00 到晚上 7:00 之间发生的流量。
如需生成模板上下文，请执行以下步骤：
在 Antigravity CLI 中输入以下提示：
Generate templates for the following two questions and SQL queries: 1. Question: "Show me flights from SFO to JFK" SQL: SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = 'SFO' AND CAST(info['arrival_airport'] AS STRING) = 'JFK' ORDER BY departure_time; 2. Question: "Tell me flights that can help me beat nighttime traffic if traveling from New York" SQL: SELECT CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['departure_time'] AS STRING) AS departure_time FROM flights WHERE CAST(info['departure_city'] AS STRING) = 'New York' AND ( EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 17 OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 19 ) ORDER BY departure_time;智能体会将您的输入转换为特定格式，从而优化上下文集在各种用户查询中的表现。如需了解详情，请参阅上下文集概览。
查看生成的查询模板。您可以将查询模板保存为新的代理上下文文件，也可以将其附加到现有代理上下文文件中。
提示智能体保存模板：
Save it to context_set.json.智能体会在同一目录中创建该文件，并添加以下内容：
{ "templates": [ { "nl_query": "Show me flights from SFO to JFK", "sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = 'SFO' AND CAST(info['arrival_airport'] AS STRING) = 'JFK' ORDER BY departure_time", "intent": "Find flights from SFO to JFK.", "manifest": "Find flights from a given departure airport code to a given arrival airport code.", "parameterized": { "parameterized_sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = ?

生成值搜索上下文
在本部分中，您将生成值搜索上下文，以帮助上下文集逻辑使用不区分大小写的精确字符串匹配，将值短语映射到存储在 Bigtable 列中的特定值。例如，如果用户询问飞往“罗利-达勒姆”的航班，值搜索会将此映射到存储的数据库值 "Raleigh-durham"（机场代码 RDU）。
如需生成值搜索上下文，请执行以下步骤：
在智能体测试框架中输入以下提示。
Generate a case-insensitive value search on table "airports" for column "info['city']" with concept "Airport City" using match function "EXACT_MATCH_STRINGS".查看生成的值搜索定义。您可以将值搜索定义保存为新的上下文集文件，也可以将其附加到现有上下文集文件。
向智能体输入提示
Append the context to context_set.json。这会将值搜索定义添加到前面部分中创建的上下文文件中。输入为其生成了上下文集文件的数据库实例和数据库名称。
系统会使用值搜索定义更新现有上下文文件，内容如下：
{ "templates": [ { "nl_query": "Show me flights from SFO to JFK", "sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = 'SFO' AND CAST(info['arrival_airport'] AS STRING) = 'JFK' ORDER BY departure_time", "intent": "Find flights from SFO to JFK.", "manifest": "Find flights from a given departure airport code to a given arrival airport code.", "parameterized": { "parameterized_sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = ?

How many flights depart from the west side?系统会调用 MCP 工具来回答此问题。由于数据库未定义
the west side，QueryData 会假设一个西海岸机场列表，并返回航班数量和说明，智能体会在回答中使用这些信息来澄清假设：There are 253 flights departing from the west side. Please note that "the west side" is not explicitly defined in our records, so this count assumes flights departing from major West Coast airports: Los Angeles (LAX), San Francisco (SFO), San Diego (SAN), Seattle (SEA), Portland (PDX), Las Vegas (LAS), and Phoenix (PHX). If you had a different set of airports in mind, please let me know!输入与为智能体生成的查询模板中的问题类似的问题。
Help me find flights from San Francisco that avoid the evening rush hour.根据之前添加的 QueryData 上下文，MCP 工具知道
evening traffic发生在下午 5 点到晚上 7 点之间。MCP 工具会返回相关数据，供智能体用于构建回答。Here are the flights departing from San Francisco that avoid the evening rush hour (defined as 5 PM to 7 PM): * UA 1532 departing at 05:50:00 * UA 1158 departing at 05:57:00 * CY 922 departing at 06:38:00 * OO 5441 departing at 07:08:00 * UA 616 departing at 07:14:00 * AA 24 departing at 07:14:00 * B6 434 departing at 08:00:00 * AA 242 departing at 08:18:00 * UA 1739 departing at 08:22:00 * OO 6336 departing at 08:32:00 * US 1784 departing at 08:47:00 * DL 1631 departing at 09:00:00 * DL 1106 departing at 09:06:00 * OO 5427 departing at 09:06:00 * CY 352 departing at 09:25:00根据您在 QueryData 智能体上下文中添加的概念类型输入一个问题。
Show me flights to Raleigh-Durham根据之前添加的值搜索上下文，智能体能够理解“Raleigh-Durham”与存储的城市
"Raleigh-durham"（机场代码RDU）相匹配，并返回相关数据，供智能体在构建回答时使用。Here is the flight heading to Raleigh-Durham (RDU): * Flight UA 1568 departs from San Francisco (SFO) at Gate A30 on 2025-01-02 at 14:55:00 and arrives at Raleigh-Durham (RDU) at Gate A26 on 2025-01-02 at 23:03:00.
迭代智能体性能
通过 ADK Web 界面，您可以检查 Gemini 数据分析 QueryData MCP 工具的请求和回答。您可以使用此响应来观察工具响应，例如生成的 SQL 查询、结果集、意图说明、消除歧义问题和自然语言回答，以帮助您确认代理回答的正确性。
例如，对于您之前输入的文本 How many flights depart from the west side?，点击代理气泡。在左侧导航栏的事件标签页中，展开 functionResponse 以查看以下响应。
{"result": "{"generatedQuery":"SELECT COUNT(*) AS flight_count FROM flights WHERE CAST(info['departure_airport'] AS STRING) IN ('LAX', 'SFO', 'SAN', 'SEA', 'PDX', 'LAS', 'PHX')","intentExplanation":"The user is asking for the number of flights departing from the 'west side'. Since there is no explicit definition or column for 'west side' in the schema, I will assume this refers to major airports on the West Coast of the United States (e.g., LAX, SFO, SAN, SEA, PDX, LAS, PHX).","queryResult":{"columns":[{"name":"flight_count"}],"rows":[{"values":[{"value":"253"}]}],"totalRowCount":"1"},"naturalLanguageAnswer":"There are 253 flights departing from West Coast airports (LAX, SFO, SAN, SEA, PDX, LAS, PHX)."}"}
提高回答的准确性
您可以通过添加更多上下文，不断提高 Gemini 数据分析 QueryData 工具回答的准确性。使用上下文工程智能体生成上下文，然后将更新后的上下文集文件上传到现有的 flights-assistant 数据智能体。如需了解详情，请参阅在 Bigtable Studio 中管理上下文集。控制台会在您上传新上下文后立即提取这些内容，让您能够在不中断应用运行的情况下提高智能体的准确性。
多个智能体
在开发环境中，您可以在 tools.yaml 文件中为工具分配不同的名称，从而对多个数据智能体上下文执行 A/B 测试。例如，您可以通过定义两个具有不同名称（例如 cloud_gda_query_tool_v1 和 cloud_gda_query_tool_v2）的 cloud-gemini-data-analytics-query 工具来创建唯一的 tools.yaml 配置。通过此设置，您可以实现应用逻辑，以编程方式选择相应的工具名称，从而选择所需的上下文版本。
以下示例 tools.yaml 展示了如何为数据库来源设置多个数据智能体：
kind: source
name: gda-api-source
type: cloud-gemini-data-analytics
projectId: PROJECT_ID
---
kind: tool
