This document describes how you can use Gemini, an AI-powered collaborator in Google Cloud, to help you do the following in Cloud SQL Studio:
- Generate SQL queries using natural language prompts
- Complete SQL statements in the query editor
- Explain SQL queries in the query editor
Learn how and when Gemini for Google Cloud uses your data.
This document is intended for database administrators and data engineers who are familiar with SQL, data analysis, and Cloud SQL. If you're new to Cloud SQL, see Cloud SQL overview.
Before you begin
- Ensure that you have set up Gemini in Databases.
- To complete the tasks in this document, ensure that you have the necessary Identity and Access Management (IAM) permissions.
- Confirm access to Cloud SQL Studio. If you don't have access to Cloud SQL Studio, then see Cloud SQL Studio required roles and permissions
Optional: To follow along with the examples in this document, create a
Singers
table using the following schema:CREATE TABLE Singers ( SingerId BIGINT PRIMARY KEY, FirstName VARCHAR(1024), LastName VARCHAR(1024), SingerInfo VARBINARY(MAX), BirthDate DATETIMEOFFSET );
After you create the
Singers
table, click refreshRefresh to update your database schema.
Required roles and permissions
To get the permissions that you need to complete the tasks in this document,
ask your administrator to grant you the
Cloud SQL Admin (roles/cloudsql.admin
) IAM role on the project.
For more information about granting roles, see Manage access to projects, folders, and organizations.
You might also be able to get the required permissions through custom roles or other predefined roles.
You also need the cloudaicompanion.companions.generateChat
permission to use
explain SQL statements in the query editor and
cloudaicompanion.companions.generateCode
to use
help me code.
Generate SQL queries using natural language prompts
You can give Gemini natural language comments (or prompts) to generate queries that are based on your schema. For example, you can prompt Gemini to generate SQL in response to the following prompts:
- "Create a table that tracks customer satisfaction survey results."
- "Add a date column called birthday to the Singers table."
- "How many singers were born in the 90s?"
If your schema changes, such as addition of a new table or column, then click refreshRefresh to update your schema before using Gemini.
To generate SQL in Cloud SQL with Gemini assistance, follow these steps:
In the Google Cloud console, go to the Cloud SQL page.
Select an instance from the list.
In the navigation menu, click Cloud SQL Studio.
Sign in to Cloud SQL Studio using the name of your database, username, and password. The Explorer pane displays a list of objects in your database.
In the taskbar, click pen_sparkGemini to view Gemini features in Cloud SQL.
Ensure that Comment-to-query generation is enabled.
To query your database, click
New SQL editor tab.To generate SQL, type a comment in the query editor starting with
--
followed by a single-line comment, and then press Return or Enter.For example, enter the following prompt:
-- add a row to table singers
Press Return or Enter. Gemini generates SQL that's similar to the following:
INSERT INTO Singers (SingerId, FirstName, LastName, BirthDate) VALUES (1, 'Alex', 'M.', '1977-10-16');
To continue the example using the
Singers
table, enter the following prompt:-- show all singers born in the 70s
Gemini generates SQL that's similar to the following:
SELECT * FROM Singers WHERE Singers.BirthDate BETWEEN '1970-01-01' AND '1979-12-31'
Review the SQL suggestion and take any of the following actions:
- To view the options for accepting the SQL generated by Gemini,
hold the pointer over the query. The following options are displayed:
- Accept: To accept the suggested query, press
Tab
, then click Run. - Accept word: To accept the suggested query partially,
press
Control
+Right arrow
. (orCommand
+Right arrow
on macOS), then click Run.
- Accept: To accept the suggested query, press
- To edit the original SQL, press
Tab
, edit the SQL, and then click Run. - To dismiss the suggestion, press
Esc
or continue typing.

Help me code tool
To use the Help me code tool, follow these steps:
In the Google Cloud console, go to the Cloud SQL page.
Select an instance from the list.
In the navigation menu, click Cloud SQL Studio.
Sign in to Cloud SQL Studio using the name of your database, username, and password. The Explorer pane displays a list of objects in your database.
To query your database, click the
New tab.Click pen_spark Help me code next to the query editor.
In the Help me code window, enter a prompt. For example,
add a row to table singers
and click Generate.Gemini generates SQL that's similar to the following:
INSERT INTO Singers (SingerId, FirstName, LastName, BirthDate) VALUES (1, Alex, 'M.', '1977-10-16');
Review the generated SQL and take any of the following actions:
- To accept SQL generated by Gemini, click Insert to insert the statement into the query editor. Then click Run to execute the suggested SQL.
- To ask Gemini to generate a new query, click Edit. After you've edited your prompt, click Update. You can then decide to accept the new generated statement or dismiss the suggestion.
- To dismiss the suggestion, close the Help me code window.
Complete SQL statements in the query editor
To help you write SQL code, Gemini in Cloud SQL provides AI-assisted code completion suggestions. With Gemini enabled, when you enter text in the Cloud SQL Studio query editor, Gemini predicts and autofills SQL code.
To use inline code suggestions, follow these steps:
In the Google Cloud console, go to the Cloud SQL page.
Select an instance from the list.
In the navigation menu, click Cloud SQL Studio.
Sign in to Cloud SQL Studio using the name of your database, username, and password. The Explorer pane displays a list of objects in your database.
In the taskbar, click pen_sparkGemini to view Gemini features in Cloud SQL.
Select SQL completion.
To query your database, click the
New SQL editor tab.Enter a query and a space or newline at the end of the line. As you enter text, Gemini shows suggested SQL that's based on the supported objects in the selected database's schema.
For example, to add a row to the
Singers
table, begin to write the following query:INSERT INTO Singers
Gemini suggests SQL that's similar to the following:
INSERT INTO Singers (SingerId, FirstName, LastName, BirthDate) VALUES (1, 'Marc', 'Singer', '1970-03-24')
Review the SQL suggestion and take any of the following actions:
- To view the options for accepting the SQL generated by Gemini,

Explain SQL statements in the query editor
You can use Gemini in Cloud SQL to explain SQL queries in natural language. This explanation can help you understand the syntax, underlying schema, and business context for complex or long queries.
In the Google Cloud console, go to the Cloud SQL page.
Select an instance from the list.
In the navigation menu, click Cloud SQL Studio.
Sign in to Cloud SQL Studio using the name of your database, username, and password. The Explorer pane displays a list of objects in your database.
