Granting privileges in IBM Db2 involves using SQL statements to assign specific permissions to users or roles. Here’s a general guide on how to grant privileges for tables and procedures:

Granting Privileges on Tables

Granting SELECT Privilege:

GRANT SELECT ON TABLE schema_name.table_name TO USER user_name;

Granting INSERT Privilege:

GRANT INSERT ON TABLE schema_name.table_name TO USER user_name;

Granting UPDATE Privilege:

GRANT UPDATE ON TABLE schema_name.table_name TO USER user_name;

Granting DELETE Privilege:

GRANT DELETE ON TABLE schema_name.table_name TO USER user_name;

Granting ALL Privileges:

GRANT ALL ON TABLE schema_name.table_name TO USER user_name;

Granting Privileges on Procedures

Granting EXECUTE Privilege:

GRANT EXECUTE ON PROCEDURE schema_name.procedure_name TO USER user_name;

Granting Privileges to Roles

You can also grant privileges to roles, which can then be assigned to users:

Creating a Role:
```
CREATE ROLE role_name;
```

Granting Privileges to a Role:

GRANT SELECT, INSERT ON TABLE schema_name.table_name TO ROLE role_name;

Granting a Role to a User:
```
GRANT role_name TO USER user_name;
```

Revoking Privileges

To revoke privileges, you can use the REVOKE statement:

Revoking SELECT Privilege:

REVOKE SELECT ON TABLE schema_name.table_name FROM USER user_name;

Revoking EXECUTE Privilege:

REVOKE EXECUTE ON PROCEDURE schema_name.procedure_name FROM USER user_name;

Notes

Replace schema_name, table_name, procedure_name, user_name, and role_name with the actual names in your database.
Ensure you have the necessary administrative privileges to grant or revoke permissions.
You can also use PUBLIC to grant privileges to all users, but this should be done with caution.

These SQL statements should be executed in the context of your Db2 database, using a tool or interface that allows you to run SQL commands against your Db2 instance.
