3. 事前準備

啟用 API

執行下列指令，啟用所有必要的 API：

gcloud services enable alloydb.googleapis.com \
                       compute.googleapis.com \
                       cloudresourcemanager.googleapis.com \
                       servicenetworking.googleapis.com \
                       aiplatform.googleapis.com \
                       geminidataanalytics.googleapis.com

API 簡介

AlloyDB API (alloydb.googleapis.com) 可讓您建立、管理及擴充 AlloyDB for PostgreSQL 叢集。這項服務提供與 PostgreSQL 相容的全代管資料庫服務，專為要求嚴苛的企業交易和分析工作負載而設計。
Compute Engine API (compute.googleapis.com) 可讓您建立及管理虛擬機器 (VM)、永久磁碟和網路設定。這個服務提供執行工作負載所需的基礎架構即服務 (IaaS) 基礎，並為許多代管服務代管基礎架構。
Cloud Resource Manager API (cloudresourcemanager.googleapis.com) 可讓您以程式輔助方式管理 Google Cloud 雲端專案的中繼資料和設定。您可以在專案階層中整理資源、處理 Identity and Access Management (IAM) 政策，以及驗證權限。
Service Networking API (servicenetworking.googleapis.com) 可讓您自動設定虛擬私有雲 (VPC) 網路與 Google 代管服務之間的私人連線。您必須建立服務 (例如 AlloyDB) 的私人 IP 存取權，才能與其他資源安全地通訊。
Vertex AI API (aiplatform.googleapis.com) 可讓應用程式建構、部署及擴充機器學習模型。這個平台提供統一的介面，方便您使用所有 Google Cloud AI 服務，包括存取生成式 AI 模型 (如 Gemini) 和模型訓練。
資料分析 API (geminidataanalytics.googleapis.com) 可讓應用程式在 BI 產品中使用一般 AI 功能。

4. 佈建 AlloyDB

建立 AlloyDB 叢集和主要執行個體。

建立私人 IP 範圍

AlloyDB 需要虛擬私有雲中的私人 IP 範圍。假設您使用 default 虛擬私有雲網路：

建立私人 IP 範圍：

gcloud compute addresses create psa-range \
    --global \
    --purpose=VPC_PEERING \
    --prefix-length=24 \
    --description="VPC private service access" \
    --network=default

建立私人連線：

gcloud services vpc-peerings connect \
    --service=servicenetworking.googleapis.com \
    --ranges=psa-range \
    --network=default

建立 AlloyDB 叢集

為 postgres 使用者建立密碼：

export PGPASSWORD=`openssl rand -hex 12`
echo $PGPASSWORD

建立免費試用叢集 (「試用」)，或標準叢集 (「標準」)，如果不是第一次：

export REGION=us-central1
export ADBCLUSTER=alloydb-next26-ai-demo-01

gcloud alloydb clusters create $ADBCLUSTER \
    --password=$PGPASSWORD \
    --network=default \
    --region=$REGION \
    --subscription-type=TRIAL

建立主要執行個體：

gcloud alloydb instances create $ADBCLUSTER-pr \
    --instance-type=PRIMARY \
    --cpu-count=8 \
    --region=$REGION \
    --cluster=$ADBCLUSTER

5. 設定資料庫權限

啟用 Vertex AI 權限，產生嵌入內容

PROJECT_ID=$(gcloud config get-value project)
gcloud projects add-iam-policy-binding $PROJECT_ID \
  --member="serviceAccount:service-$(gcloud projects describe $PROJECT_ID --format="value(projectNumber)")@gcp-sa-alloydb.iam.gserviceaccount.com" \
  --role="roles/aiplatform.user"

啟用 Data Access API

您必須在 AlloyDB 叢集上啟用 Data Access API，才能使用 QueryData 脈絡建立範本，協助從自然語言建立可預測的 SQL 陳述式。

在同一個終端機分頁中執行：

PROJECT_ID=$(gcloud config get-value project)
REGION=us-central1
ADBCLUSTER=alloydb-next26-ai-demo-01
curl -X PATCH \
 -H "Authorization: Bearer $(gcloud auth print-access-token)" \
 -H "Content-Type: application/json" \
 https://alloydb.googleapis.com/v1alpha/projects/$PROJECT_ID/locations/$REGION/clusters/$ADBCLUSTER/instances/$ADBCLUSTER-pr?updateMask=dataApiAccess \
 -d '{
   "dataApiAccess": "ENABLED",
 }'

啟用 IAM 驗證

如要使用代理程式工具，您必須在執行個體上啟用 IAM 驗證，然後將自己新增為使用者。

在同一個終端機分頁中執行下列指令，在執行個體上啟用 IAM：

PROJECT_ID=$(gcloud config get-value project)
REGION=us-central1
ADBCLUSTER=alloydb-next26-ai-demo-01
gcloud beta alloydb instances update $ADBCLUSTER-pr \
   --database-flags alloydb.iam_authentication=on \
   --region=$REGION \
   --cluster=$ADBCLUSTER \
   --project=$PROJECT_ID \
   --update-mode=FORCE_APPLY

將自己新增為 AlloyDB 使用者：

REGION=us-central1
ADBCLUSTER=alloydb-next26-ai-demo-01
gcloud alloydb users create $(gcloud config get-value account) \
--cluster=$ADBCLUSTER \
--region=$REGION \
--type=IAM_BASED \
--db-roles=alloydbsuperuser

6. 準備範例資料庫

連線至 AlloyDB Studio

前往 Google Cloud 控制台的「AlloyDB for Postgres」頁面。
按一下主要執行個體。
按一下左側導覽列中的「AlloyDB Studio」。
選取 postgres 資料庫
透過 IAM database authentication 進行驗證

建立資料庫

在查詢編輯器中執行下列 SQL：

CREATE DATABASE conference_db;

切換至 conference_db 資料庫：

按一下 AlloyDB studio 畫面左上方的 Current user 按鈕
按一下「Switch user/database」按鈕
選取新建立的 conference_db 資料庫。

啟用 pgvector

確認已啟用標準 vector 擴充功能：

CREATE EXTENSION IF NOT EXISTS vector;

載入範例資料

執行下列 SQL 指令碼，建立結構定義並填入範例資料：

1. 清除先前任何衝突的表格

DROP TABLE IF EXISTS public.attendees_sessions CASCADE;

輸出內容應該會指出執行成功。確認資料表已填入資料。舉例來說，請確認工作階段資料表中有 100 個工作階段：

SELECT count(*) from public.session;

7. 啟用 AI 查詢引擎

使用 AI 函式前，請務必先在資料庫中啟用 AI 查詢引擎。

在 AlloyDB Studio 中執行下列 SQL (conference_db 內容)：

CREATE EXTENSION IF NOT EXISTS google_ml_integration CASCADE;
ALTER DATABASE conference_db SET google_ml_integration.enable_ai_query_engine = 'on';

確認擴充功能已啟用：

SELECT extversion FROM pg_extension WHERE extname = 'google_ml_integration';

預期輸出內容應顯示 1.5.9 或更高。

8. 使用 AI 函式 (運算子)

現在，我們來搭配 ai.if 和 ai.rank 函式，使用 AI 驅動的語意篩選和評分功能。

使用 ai.if 進行語意篩選

如果沒有完全相符的關鍵字，標準文字比對可能會遺漏工作階段。讓我們使用 ai.if 尋找有關「生成式 AI」的課程。

在 AlloyDB Studio 中執行下列 SQL：

SELECT session_name, full_description
FROM public.session
WHERE
  ai.if(
    prompt => 'Is this session description about Generative AI, LLMs or AI agents? ' || full_description
  );

即使使用不同術語，結果中也會顯示相關工作階段。

使用 ai.rank 進行語意評分

讓我們根據課程的入門難易度為課程評分。我們可以使用 ai.rank 進行語意評分。

執行下列 SQL：

SELECT session_name, full_description, 
  ai.rank(
    prompt => 'On a scale of 0 to 1, how suitable is this session for a beginner? 1 being very suitable, 0 being advanced. Session: ' || full_description
  ) as beginner_friendly_score
FROM public.session
ORDER BY beginner_friendly_score DESC;

這項功能可根據會議參與者的個人資料，提供個人化建議。

9. 實作混合搜尋

混合型搜尋結合了關鍵字搜尋 (詞彙) 的精確度，以及向量搜尋 (語意) 的脈絡解讀能力。我們會為兩者建立索引，並使用倒數排名融合 (RRF) 合併結果。

啟用掃描功能

確認已啟用 scann 和 rum 擴充功能：

CREATE EXTENSION IF NOT EXISTS alloydb_scann;
CREATE EXTENSION IF NOT EXISTS rum;

建立索引

由於我們的結構定義會使用嵌入的產生資料欄 (full_description_embedding)，因此系統會在插入時自動計算。我們只需要建立適當的索引，就能快速擷取資料。

建立 RUM 索引 (FTS 索引)，用於全文關鍵字搜尋；建立 ScaNN 索引，用於快速向量相似度搜尋。

在 AlloyDB Studio 中執行下列 SQL：

-- Create RUM index for text search on session descriptions
CREATE INDEX session_text_idx ON public.session USING RUM (description_tsvector rum_tsvector_ops);

-- Create ScaNN index for vector search on session embeddings
CREATE INDEX session_vector_idx ON public.session
  USING scann (full_description_embedding cosine)
  WITH (num_leaves=10);

使用 RRF 執行混合型搜尋

現在我們要尋找 fast similarity search 的場次，但重點是 AlloyDB 的 ScaNN。

我們會使用語意搜尋和關鍵字搜尋，並以 RRF 合併結果。

執行下列 SQL：

-- Enable preview features for the AI Query Engine if not already set
SET google_ml_integration.enable_preview_ai_functions = true;
SELECT s.session_id, s.session_name, s.full_description
FROM public.session s
JOIN ai.hybrid_search(
  search_inputs => ARRAY[
      '{
        "data_type": "vector",
        "table_name": "session",
        "key_column": "session_id",
        "vec_column": "full_description_embedding",
        "distance_operator": "public.<=>",
        "limit": 5,
        "query_vector": "ai.embedding(''text-embedding-005'', ''fast similarity search'')::vector"
      }'::JSONB,
      '{
        "data_type": "text",
        "table_name": "session",
        "key_column": "session_id",
        "text_column": "description_tsvector",
        "limit": 5,
        "ranking_function": "<=>",
        "query_text_input": "ScaNN"
      }'::JSONB
  ]
) AS search_results
on s.session_id = search_results.id;

您應該會看到相關的會話相似度搜尋結果，其中大部分會顯示與 ScaNN 相關的會話。

10. 在 AlloyDB Studio 中使用 QueryData

AlloyDB AI 可讓您使用 QueryData，從自然語言輸入內容生成準確且可預測的 SQL 陳述式。在本節中，您將瞭解如何建立 QueryData 內容 (範本)，並直接在 AlloyDB Studio 中測試。

建立 QueryData 脈絡資料

QueryData Context 是 JSON 檔案，內含查詢範本和層面，可為 AI 模型提供必要資料和指示，以便使用正確的 SQL 查詢或 SQL 查詢部分。

讓我們看看為會議結構定義設計的 JSON 內容範例。請注意，我們會確保資料表名稱符合結構定義 (例如 public.session)。

以下是我們要使用的 JSON 內容 - 請將其儲存在筆電/電腦的本機 .json 檔案中：

{
  "templates": [
    {
      "nlQuery": "Advanced sessions that are almost full",
      "sql": "SELECT session_name, remaining_capacity, session_date, session_start_time FROM session WHERE learning_level = 'Advanced' AND remaining_capacity > 0 AND remaining_capacity < 5 ORDER BY remaining_capacity ASC",
      "intent": "Advanced sessions that are almost full (remaining capacity less than 5)",
      "manifest": "Advanced sessions that are almost full (remaining capacity less than 5)",
      "parameterized": {
        "parameterized_intent": "$1 sessions that are almost full (remaining capacity less than 5)",
        "parameterized_sql": "SELECT session_name, remaining_capacity, session_date, session_start_time FROM public.session WHERE learning_level = $1 AND remaining_capacity > 0 AND remaining_capacity < 5 ORDER BY remaining_capacity ASC"
      }
    },
    {
      "nlQuery": "Find sessions about Gemini",
      "sql": "SELECT name, format, session_date, description FROM ((SELECT s1.session_name AS name, s1.session_format AS format, s1.session_date AS session_date, s1.full_description AS description, (s1.full_description_embedding <=> public.embedding('text-embedding-005', 'Gemini')::public.vector) AS distance FROM public.session s1 ORDER BY distance LIMIT 10) UNION ALL (SELECT s2.session_name AS name, s2.session_format AS format, s2.session_date AS session_date, t.topic_desc AS description, (t.embedding <=> public.embedding('text-embedding-005', 'Gemini')::public.vector) AS distance FROM public.session s2 INNER JOIN public.session_topic_mapping stm ON s2.session_id = stm.session_id INNER JOIN public.session_topic t ON stm.topic = t.topic ORDER BY distance LIMIT 10)) AS combined_results ORDER BY distance LIMIT 10",
      "intent": "Find sessions about Gemini",
      "manifest": "Find sessions about a given topic",
      "parameterized": {
        "parameterized_intent": "Find sessions about $1",
        "parameterized_sql": "SELECT name, format, session_date, description FROM ((SELECT s1.session_name AS name, s1.session_format AS format, s1.session_date AS session_date, s1.full_description AS description, (s1.full_description_embedding <=> public.embedding('text-embedding-005', '$1')::public.vector) AS distance FROM public.session s1 ORDER BY distance LIMIT 10) UNION ALL (SELECT s2.session_name AS name, s2.session_format AS format, s2.session_date AS session_date, t.topic_desc AS description, (t.embedding <=> public.embedding('text-embedding-005', '$1')::public.vector) AS distance FROM public.session s2 INNER JOIN public.session_topic_mapping stm ON s2.session_id = stm.session_id INNER JOIN public.session_topic t ON stm.topic = t.topic ORDER BY distance LIMIT 10)) AS combined_results ORDER BY distance LIMIT 10"
      }
    }
  ]
}

在 AlloyDB Studio 中載入 QueryData 脈絡資料

如要使用「查詢資料」環境，我們需要透過 AlloyDB Studio 將資料上傳至資料庫。

在 Google Cloud 控制台中開啟 AlloyDB Studio。
左側面板底部會顯示「內容集」和三點圖示。
按一下該圖示，然後選擇「建立內容集」。
填寫對話方塊：
- Name (名稱)：conference_context
- 說明：Conference Sessions QueryData Context
- 上傳結構定義檔案：上傳使用上述內容建立的 JSON 檔案。
儲存

測試 QueryData 脈絡資料

上傳後，即可直接在 AlloyDB Studio 中測試。

點選剛建立的脈絡旁的三點圖示，然後選擇「測試脈絡集」 (或在查詢編輯器中使用 Gemini 藥丸，然後選取這個脈絡)。
在 Gemini SQL 程式碼生成提示中，輸入符合範本的自然語言查詢：
```
Advanced sessions that are almost full
```
產生 SQL，並確認是否與我們提供的範本相符。
在自然語言提示中將「進階」變更為「初學者」，然後試試參數化查詢，看看是否會調整！

11. 清理

刪除 AlloyDB 叢集

如要避免系統持續向您的 Google Cloud 帳戶收費，請刪除本程式碼研究室建立的資源。

在 Cloud Shell 中執行下列指令，刪除 AlloyDB 叢集 (這也會刪除執行個體)：

export REGION=us-central1
export ADBCLUSTER=alloydb-next26-ai-demo-01

echo "=> Deleting AlloyDB Cluster (${ADBCLUSTER})..."
gcloud alloydb clusters delete $ADBCLUSTER --region=$REGION --force

或者，如果您是特地為了這個程式碼研究室建立專案，可以刪除整個專案。

刪除 IP 範圍和 vpc-peering

PROJECT_ID=$(gcloud config get-value project)
echo "=> Deleting Service Networking VPC Peering..."
gcloud compute networks peerings delete servicenetworking-googleapis-com \
    --network=default \
    --project=${PROJECT_ID} --quiet || true

echo "=> Deleting Allocated IP Range for Managed Services..."
gcloud compute addresses delete psa-range \
    --global \
    --project=${PROJECT_ID} --quiet || true

刪除本機檔案

刪除在 Work with QueryData in AlloyDB Studio 步驟中建立的本機 JSON 檔案。
