SQL> select ai narrate how many customers exist;
RESPONSE
------------------------------------------------------
There are a total of 55,500 customers in the database.
SQL> select ai chat how many customers exist;
RESPONSE
--------------------------------------------------------------------------------
It is impossible to determine the exact number of customers that exist as it con
stantly changes due to various factors such as population growth, new businesses
, and customer turnover. Additionally, the term "customer" can refer to individu
als, businesses, or organizations, making it difficult to provide a specific num
ber.
SQL> select ai explainsql how many customers in San Francisco are married;
RESPONSE
--------------------------------------------------------------------------------
SELECT COUNT(*) AS customer_count
FROM SH.CUSTOMERS AS c
WHERE c.CUST_STATE_PROVINCE = 'San Francisco' AND c.CUST_MARITAL_STATUS = 'Married';
Explanation:
- We use the 'SH' table alias for the 'CUSTOMERS' table for better readability.
- The query uses the 'COUNT(*)' function to count the number of rows that match the given conditions.
- The 'WHERE' clause is used to filter the results:
- 'c.CUST_STATE_PROVINCE = 'San Francisco'' filters customers who have 'San Francisco' as their state or province.
- 'c.CUST_MARITAL_STATUS = 'Married'' filters customers who have 'Married' as their marital status.
The result of this query will give you the count of customers in San Francisco who are married, using the column alias 'customer_count' for the result.
Remember to adjust the table and column names based on your actual schema if they differ from the example.

SQL> select ai explainsql how many customers in San Francisco are married;
RESPONSE
Here is the Oracle SQL query to find the number of customers in San Francisco who are married:
```
SELECT COUNT(*)
FROM "SH"."CUSTOMERS" c
WHERE c."CUST_CITY" = 'San Francisco'
AND c."CUST_MARITAL_STATUS" = 'Married';
```
Explanation:
* We use the `COUNT(*)` aggregate function to count the number of rows that match the conditions.
* We specify the table alias `c` for the `"SH"."CUSTOMERS"` table to make the query more readable.
* We use the `WHERE` clause to filter the rows based on two conditions:
+ `c."CUST_CITY" = 'San Francisco'`: We filter the rows where the customer's city is San Francisco.
+ `c."CUST_MARITAL_STATUS" = 'Married'`: We filter the rows where the customer's marital status is Married.
* The double quotes around the table and column names are used to make the query case-sensitive, as required in Oracle SQL.
Note: The column names and table names are assumed to be case-sensitive, so we enclose them in double quotes. If the column names and table names are not case-sensitive, you can remove the double quotes.

SQL> select ai chat what is Autonomous Database;
RESPONSE
An Autonomous Database is a type of database that uses artificial intelligence (AI) and machine learning (ML) to automate many of the administrative and maintenance tasks typically performed by a database administrator (DBA). This allows the database to manage itself, without human intervention, to a large extent.
Autonomous databases are designed to be self-driving, self-securing, and self-repairing, which means they can:
1. **Automate administrative tasks**: Such as provisioning, patching, upgrading, and tuning, which frees up DBAs to focus on higher-level tasks.
2. **Optimize performance**: By automatically adjusting parameters, indexing, and caching to ensure optimal performance and efficiency.
3. **Detect and respond to security threats**: By using AI-powered security tools to identify and respond to potential security threats in real-time.
4. **Heal itself**: By automatically detecting and repairing errors, corruption, or other issues that may arise.
5. **Scale up or down**: To match changing workload demands, without the need for manual intervention.
The benefits of Autonomous Databases include:
1. **Increased efficiency**: By automating routine tasks, DBAs can focus on more strategic activities.
2. **Improved performance**: Autonomous databases can optimize performance in real-time, leading to faster query response times and better overall system performance.
3. **Enhanced security**: AI-powered security tools can detect and respond to threats more quickly and effectively than human administrators.
4. **Reduced costs**: By minimizing the need for manual intervention, Autonomous Databases can help reduce labor costs and improve resource utilization.
5. **Improved reliability**: Autonomous Databases can detect and repair errors more quickly, reducing downtime and improving overall system reliability.
Oracle Autonomous Database is a popular example of an Autonomous Database, which was introduced in 2018. Other vendors, such as Amazon, Microsoft, and Google, also offer Autonomous Database services as part of their cloud offerings.
In summary, Autonomous Databases are designed to be self-managing, self-optimizing, and self-healing, which can lead to improved performance, security, and efficiency, while reducing costs and administrative burdens.

- We use the 'SH' table alias for the 'CUSTOMERS' table for better readability.
- The query uses the 'COUNT(*)' function to count the number of rows that match the given conditions.
- The 'WHERE' clause is used to filter the results:
- 'c.CUST_STATE_PROVINCE = 'San Francisco'' filters customers who have 'San Francisco' as their state or province.
- 'c.CUST_MARITAL_STATUS = 'Married'' filters customers who have 'Married' as their marital status.
The result of this query will give you the count of customers in San Francisco who are married, using the column alias 'customer_count' for the result.
Remember to adjust the table and column names based on your actual schema if they differ from the example.

SQL> select ai explainsql how many customers in San Francisco are married;
RESPONSE
------------------------------------------------------------
To answer the question "How many customers in San Francisco are married?", we need to query the "SH"."CUSTOMERS" table and filter the results based on the city and marital status.
We will use table aliases to make the query more readable and ensure that the string comparisons follow the specified rules.
Here is the Oracle SQL query:
```sql
SELECT COUNT("CUST_ID") AS "Married_Customers_in_San_Francisco"
FROM "SH"."CUSTOMERS" c
WHERE c."CUST_CITY" = 'San Francisco' -- Case insensitive comparison
AND UPPER(c."CUST_MARITAL_STATUS") = UPPER('Married'); --
Case insensitive comparison
```
### Explanation:
1. **Table Alias**:
RESPONSE
------------------------------------------------------------
- We use the alias `c` for the "SH"."CUSTOMERS" table to make the query more readable.
2. **Column Selection**:
- We select the count of "CUST_ID" to get the number of customers who meet the criteria. We alias this count as "Married_Customers_in_San_Francisco" for clarity.
3. **WHERE Clause**:
- **City Filter**: `c."CUST_CITY" = 'San Francisco'`
- Since 'San Francisco' is not in double quotes, we use a case-insensitive comparison.
- **Marital Status Filter**: `UPPER(c."CUST_MARITAL_STATUS") = UPPER('Married')`
- Since 'Married' is not in double quotes, we use a case-insensitive comparison by applying the `UPPER` function to both sides of the comparison.
This query will return the number of customers in San Francisco who are married.
SQL> select ai narrate what are the top 3 customers in San Francisco;
RESPONSE
------------------------------------------------------------
The top 3 customers in San Francisco are:
- Hector Colven, with a customer ID of 8866.
- Milburn Klemm, with a customer ID of 1944.
- Gavin Xie, with a customer ID of 2579.
These customers have the highest total sales among all customers in San Francisco.
SQL> select ai chat what is Autonomous Database;
RESPONSE
------------------------------------------------------------
An Autonomous Database is a type of database management system that uses artificial intelligence (AI) and machine learning (ML) to automate many of the routine tasks typically performed by database administrators (DBAs). These tasks include provisioning, patching, backups, tuning, and security. The goal of an autonomous database is to reduce the need for human intervention, minimize errors, and optimize performance,thereby allowing organizations to focus on more strategic activities.
### Key Features of Autonomous Databases:
RESPONSE
------------------------------------------------------------
1. **Automated Provisioning**: The database can be set up and configured automatically, reducing the time and effort required to get it up and running.
2. **Self-Patching and Updates**: The database automatically applies security patches and updates without downtime, ensuring that the system remains secure and up-to-date.
3. **Self-Tuning**: The database continuously monitors its performance and adjusts settings to optimize query execution and resource utilization.
4. **Self-Backup and Recovery**: Automated backup and recovery processes ensure that data is protected and can be restored quickly in the event of a failure.
5. **Security**: Advanced security features, including threat detection and response, are built into the database to protect against cyber threats.
6. **Scalability**: The database can automatically scale resources up or down based on demand, ensuring optimal performance and cost efficiency.
7. **Monitoring and Diagnostics**: Real-time monitoring and diagnostics help identify and resolve issues before they impact performance.
RESPONSE
------------------------------------------------------------

SELECT AI narrate how can I deploy an oracle machine learning model;
RESPONSE
To deploy an Oracle Machine Learning model, you would first build your model within the Oracle database. Once your in-database models are built, they become immediately available for use, for instance, through a SQL query using the prediction operators built into the SQL language.
The model scoring, like model building, occurs directly in the database, eliminating the need for a separate engine or environment within which the model and corresponding algorithm code operate. You can also use models from a different schema (user account) if the appropriate permissions are in place.

Tema principal: Ejemplos de uso de Select AI
Ejemplo: selección de IA con modelos de transformador en la base de datos
En este ejemplo se muestra cómo importar un modelo de transformador previamente entrenado que se almacena en el almacenamiento de objetos de Oracle en la instancia de Oracle Database 23ai y, a continuación, utilizar el modelo importado en la base de datos en el perfil Select AI para generar incrustaciones de vectores para fragmentos de documentos y peticiones de datos de usuario.
Para utilizar modelos de transformadores en la base de datos en su perfil Select AI, asegúrese de tener:
-
el modelo previamente entrenado importado en la instancia de Oracle Database 23ai.
-
opcionalmente, acceda al almacenamiento de objetos de Oracle.
Importación de un modelo de transformador previamente entrenado a Oracle Database 23ai desde Oracle Object Storage
Revise los pasos de Importación de modelos entrenados previamente en formato ONNX para la generación de vectores en la base de datos y el blog Modelo de generación de embebido incorporado previamente para Oracle Database 23ai para importar un modelo de transformador entrenado previamente en la base de datos.
En el siguiente ejemplo se muestra cómo importar un modelo de transformador mantenido desde el almacenamiento de objetos de Oracle a la base de datos y, a continuación, ver el modelo importado.

Estos ejemplos ilustran cómo utilizar modelos de transformadores en la base de datos dentro de un perfil Select AI. Un perfil se configura solo para generar incrustaciones de vectores, mientras que el otro admite tanto las acciones Select AI como la creación de índices vectoriales.
Revise Examples of Privileges to Run Select AI para completar los requisitos.
A continuación se muestra un ejemplo para generar incrustaciones de vectores únicamente:
BEGIN

/A continuación se muestra un ejemplo de acciones generales de selección de IA y generación de índices vectoriales donde puede especificar un proveedor de IA soportado. En este ejemplo se utilizan el perfil y las credenciales de OCI Gen AI. Consulte Seleccionar su proveedor de IA y LLM para obtener una lista de proveedores admitidos. Sin embargo, si desea utilizar un modelo de transformador en la base de datos para generar incrustaciones de vectores, utilice "database: <MY_ONNX_MODEL>" en el atributo embedding_model:
BEGIN
DBMS_CLOUD.CREATE_CREDENTIAL(

);
END;
/Uso de Select AI con un modelo de transformador en la base de datos de otro esquema
En este ejemplo se muestra cómo utilizar Select AI con un modelo de transformador en la base de datos si otro propietario de esquema es propietario del modelo. Especifique schema_name.object_name como nombre totalmente cualificado del modelo en el atributo embedding_model. Si el usuario actual es el propietario del esquema o es propietario del modelo, puede omitir el nombre del esquema.
Asegúrese de tener los siguientes privilegios si un propietario de esquema diferente es propietario del modelo:
- Privilegio del sistema
CREATE ANY MINING MODEL - Privilegio del sistema
SELECT ANY MINING MODEL - Privilegio de objeto
SELECT MINING MODELen el modelo específico
Para otorgar un privilegio del sistema, debe tener otorgado el privilegio del sistema con ADMIN OPTION o el privilegio del sistema GRANT ANY PRIVILEGE.
Consulte Privilegios del sistema para Oracle Machine Learning for SQL para revisar los privilegios.
Las siguientes sentencias permiten a ADB_USER1 puntuar los datos y ver los detalles del modelo en cualquier esquema siempre que se haya otorgado acceso SELECT a los datos. Sin embargo, ADB_USER1 solo puede crear modelos en el esquema ADB_USER1.

En estos ejemplos se muestra cómo Select AI detecta automáticamente las tablas relevantes y envía metadatos solo para las tablas específicas relevantes para la consulta en Oracle Database 23ai. Para activar esta función, defina object_list_mode en automated. Esto crea automáticamente un índice vectorial denominado <profile_name>_OBJECT_LIST_VECINDEX. El índice vectorial se inicializa con atributos y valores por defecto, como refresh_rate, similarity_threshold y match_limit. Puede modificar algunos atributos mediante DBMS_CLOUD_AI.UPDATE_VECTOR_INDEX. Consulte Procedimiento UPDATE_VECTOR_INDEX para obtener más información.
Un perfil está configurado para utilizar object_list para especificar el esquema o los objetos del esquema, mientras que el otro no especifica object_list. Sin embargo, se espera la misma construcción SQL.

10Ejemplo: guía de generación de datos sintéticos con filas de ejemplo
Para guiar el servicio de IA en la generación de datos sintéticos, puede seleccionar de forma aleatoria registros existentes de una tabla. Por ejemplo, al agregar {"sample_rows": 5} al argumento params, puede enviar 5 filas de ejemplo de una tabla al proveedor de AI. En este ejemplo se generan 10 filas adicionales basadas en las filas de ejemplo de la tabla Transactions.
BEGIN
DBMS_CLOUD_AI.GENERATE_SYNTHETIC_DATA(
profile_name => 'GENAI',
object_name => 'Transactions',
owner_name => 'ADB_USER',
record_count => 10,
params => '{"sample_rows":5}'
);
END;
/Ejemplo: Personalización de la generación de datos sintéticos con peticiones de datos de usuario
El argumento user_prompt permite especificar reglas o requisitos adicionales para la generación de datos. Esto se puede aplicar a una sola tabla o como parte del argumento object_list para varias tablas. Por ejemplo, en las siguientes llamadas a DBMS_CLOUD_AI.GENERATE_SYNTHETIC_DATA, la petición de datos indica a AI que genere datos sintéticos sobre películas lanzadas en 2009.
-- Definition for the Movie table CREATE TABLE Movie
CREATE TABLE Movie (
movie_id INT PRIMARY KEY,
title VARCHAR(100),
release_date DATE,
genre VARCHAR(50),
director_id INT,
FOREIGN KEY (director_id) REFERENCES Director(director_id)
);
BEGIN
DBMS_CLOUD_AI.GENERATE_SYNTHETIC_DATA(
profile_name => 'GENAI',
object_name => 'Movie',
owner_name => 'ADB_USER',
record_count => 10,
user_prompt => 'all movies are released in 2009',
params => '{"sample_rows":5}'
);
END;
/
BEGIN
DBMS_CLOUD_AI.GENERATE_SYNTHETIC_DATA(
profile_name => 'GENAI',
object_list => '[{"owner": "ADB_USER", "name": "Director","record_count":5},
{"owner": "ADB_USER", "name": "Movie_Actor","record_count":5},
{"owner": "ADB_USER", "name": "Actor","record_count":10},
{"owner": "ADB_USER", "name": "Movie","record_count":5,"user_prompt":"all movies are released in 2009"}]'
);
END;
/Ejemplo: Mejora de la Calidad de los Datos Sintéticos mediante Estadísticas de Tabla
Si una tabla tiene estadísticas de columna o se clona a partir de una base de datos que incluye metadatos, Select AI puede utilizar estas estadísticas para generar datos que se parezcan o sean coherentes con los datos originales.
Para las columnas NUMBER, los valores alto y bajo de las estadísticas guían el rango de valores. Por ejemplo, si la columna SALARY de la tabla EMPLOYEES original oscila entre 1000 y 10000, los datos sintéticos de esta columna también estarán dentro de este rango.
Para las columnas con valores distintos, como una columna STATE con los valores CA, WA y TX, los datos sintéticos utilizarán estos valores específicos. Puede gestionar esta función mediante el parámetro {"table_statistics": true/false}. Por defecto, las estadísticas de la tabla están activadas.
BEGIN
DBMS_CLOUD_AI.GENERATE_SYNTHETIC_DATA(
profile_name => 'GENAI',
object_name => 'Movie',
owner_name => 'ADB_USER',
record_count => 10,
user_prompt => 'all movies released in 2009',
params => '{"sample_rows":5,"table_statistics":true}'
);
END;
/Ejemplo: uso de comentarios de columna para guiar la generación de datos
Si existen comentarios de columna, Select AI los incluye automáticamente para proporcionar información adicional para el LLM durante la generación de datos. Por ejemplo, un comentario en la columna Status de una tabla de transacciones puede mostrar valores permitidos, como successful, failed, pending, canceled y need manual check. También puede agregar comentarios para explicar más detalladamente la columna, dando a los servicios de IA instrucciones o sugerencias más precisas para generar datos precisos. Por defecto, los comentarios están desactivados. Consulte Parámetros opcionales para obtener más información.
-- Use comment on column
COMMENT ON COLUMN Transaction.status IS 'the value for state should either be ''successful'', ''failed'', ''pending'' or ''canceled''';
/
BEGIN
DBMS_CLOUD_AI.GENERATE_SYNTHETIC_DATA(
profile_name => 'GENAI',
object_name => 'employees',
owner_name => 'ADB_USER',
record_count => 10
params => '{"comments":true}'
);
END;
/Ejemplo: definición de valores únicos en la generación de datos sintéticos
Al generar grandes cantidades de datos sintéticos con LLM, es probable que se produzcan valores duplicados. Para evitarlo, configure una restricción única en la columna relevante. Esto garantiza que Select AI ignore las filas con valores duplicados en la respuesta del LLM. Además, para restringir valores para determinadas columnas, puede utilizar user_prompt o agregar comentarios para especificar los valores permitidos, como limitar una columna STATE a CA, WA y TX.
-- Use 'user_prompt'
BEGIN
DBMS_CLOUD_AI.GENERATE_SYNTHETIC_DATA(
profile_name => 'GENAI',
object_name => 'employees',
owner_name => 'ADB_USER',
user_prompt => 'the value for state should either be CA, WA, or TX',
record_count => 10
);
END;
/
-- Use comment on column
COMMENT ON COLUMN EMPLOYEES.state IS 'the value for state should either be CA, WA, or TX'
/Ejemplo: Mejora de la generación de datos sintéticos mediante procesamiento paralelo
Para reducir el tiempo de ejecución, Select AI divide las tareas de generación de datos sintéticos en fragmentos más pequeños para tablas sin claves primarias o con claves primarias numéricas. Estas tareas se ejecutan en paralelo, interactuando con el proveedor de IA para generar datos de manera más eficiente. El grado de paralelismo (DOP) de la base de datos, influenciado por el nivel de servicio de Autonomous Database y la configuración de ECPU u OCPU, determina el número de registros de cada proceso de fragmento. La ejecución de tareas en paralelo generalmente mejora el rendimiento, especialmente al generar grandes cantidades de datos en muchas tablas. Para gestionar el procesamiento paralelo de la generación de datos sintéticos, defina priority como parámetro opcional. Consulte Optional Parameters.
