Caller’s Rights vs. Owner’s Rights in Stored Procedures

In SQL, stored procedures can run with the privileges of either the person who calls the procedure (caller’s rights) or the person who created it (owner’s rights). This distinction affects which database objects can be accessed during execution. Choosing the right execution context ensures better access control, data protection, and operational flexibility.

How the Execution Model Affects Object Privileges

In Snowflake, caller’s rights and owner’s rights are execution modes that determine how stored procedures access objects based on privilege context. Stored procedures using caller’s rights rely on the caller’s current role and object permissions. This limits access to only what the caller can directly interact with, increasing security and reducing risk of unauthorized data manipulation.

In contrast, owner’s rights procedures execute with the privileges of the procedure’s creator, allowing broader access to database objects. This model is useful for centralizing logic while maintaining consistent access regardless of the user. 

How Caller’s-Rights Stored Procedures Work

Caller’s-rights procedures run using the active role and permissions of the user who invokes the procedure. These procedures inherit the session settings, roles, and restrictions of the caller. As a result, they are limited to the caller’s granted privileges. This model ensures tight control and is ideal when access to sensitive objects should be explicitly governed by the calling user’s role.

How Owner’s-Rights Stored Procedures Work: Advantages & Limits

Owner’s-rights procedures execute with the permissions of the user who owns the procedure, regardless of the caller’s privileges. This allows broader access to database objects and is useful for standardizing procedures across users. However, this model can lead to unintended access if not carefully managed. Additionally, owner’s rights procedures have limits—they do not inherit session variables or temporary objects from the caller and can potentially expose sensitive operations.

Choosing Between Caller’s Rights and Owner’s Rights Procedures

Deciding between the two models depends on your access control strategy. Choose caller’s rights when you want execution to respect each user’s permissions and roles, making it ideal for controlled, user-specific actions. Opt for owner’s rights when centralized logic needs consistent object access, such as shared automation tasks or internal processes. Consider the sensitivity of accessed data and the principle of least privilege when making the choice.

Understanding the difference between these two execution models is essential for writing secure, scalable, and compliant SQL code. Take time to assess the data sensitivity and user roles involved in your procedures. The more thoughtfully you structure execution rights, the easier it is to maintain clarity, enforce policies, and protect business data.

Govern Caller’s and Owner’s Rights with Confidence Using OWOX Data Marts

Balancing caller’s rights and owner’s rights is key to maintaining data security while enabling collaboration. With OWOX Data Marts, you can clearly define who owns each dataset and who can query or reuse it, ensuring both governance and flexibility. Analysts maintain control over data logic, while business users safely access only what they need.
