Providing Execute Privileges on Stored Procedures to Roles

Question

Pulumi · Accepted Answer

To provide execute privileges on stored procedures to roles, you'd typically have a resource representing the stored procedures and another one representing the grant of privileges on these procedures to roles. In the context of Pulumi and depending on the database you’re using, there are different resources available to perform these actions.

Let's say you're using Snowflake for your database needs. In Snowflake, you would use `Procedure` to create a stored procedure, and then `ProcedureGrant` to grant the execute privileges to certain roles.

Below is a TypeScript program that illustrates how you can accomplish this with Pulumi. We'll create a simple stored procedure and grant execute privileges to a role named `myRole`.

Remember that before you run this Pulumi code, you need to have the Pulumi CLI installed, be logged in to a Pulumi account, and have your Snowflake credentials configured properly, which usually involves setting them up in the Pulumi configuration or environment variables.

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as snowflake from '@pulumi/snowflake';

// Create a Snowflake Role
const myRole = new snowflake.Role("myRole", {});

// Create a Snowflake procedure
const myProcedure = new snowflake.Procedure("myProcedure", {
    database: "myDatabase",
    schema: "PUBLIC",
    name: "MyProcedureName",
    statement: `CREATE OR REPLACE PROCEDURE ...`, // Your SQL procedural code here
    returnType: "VARCHAR(100)", // Define your return type here
    language: "SQL", // The language used for the stored procedure; could be SQL or JavaScript in Snowflake
    executeAs: "CALLER", // Specifies whether to execute stored procedure as owner's rights or caller's rights
});

// Grant execute permission on the stored procedure to the role
const executeGrant = new snowflake.ProcedureGrant("executeGrant", {
    procedureName: myProcedure.name,
    privilege: "EXECUTE",
    roles: [myRole.name],
    databaseName: "myDatabase",
    schemaName: "PUBLIC",
});

// Export the role and procedure names
export const roleName = myRole.name;
export const procedureName = myProcedure.name;
```

In this program:

- We first import the necessary Pulumi and Snowflake modules.
- We then create a role in Snowflake that you would assign to users who need to execute the stored procedure.
- Next, we define our stored procedure, 'myProcedure'. The `statement` parameter is where you define the SQL procedural code. Ensure that the procedural code is valid and compatible with Snowflake.
- Then, we create a `ProcedureGrant`, which explicitly grants execute permissions to the role `myRole` on the `myProcedure` stored procedure. Note that the `roles` property is an array because you can grant permissions to multiple roles if needed.
- Last, we export the role and procedure names so the outputs can be accessed outside of Pulumi if necessary (for example, through the CLI).

To use this program, replace the placeholders in the `myProcedure` resource (e.g., database name, schema, stored procedure name, return type, and procedural code) with the actual values relevant to your Snowflake setup.
