Minimum requered permision to execute MySql stored procedures from C# app

[Andraes Zarvos]

I have a schema in MySQL '_people' which includes 1 table with two columns (person, telephone number). For simplicity lets assume that i have 4 store procedures.

SP_Find user: Return the persons telephone number (Select)
SP_Add user: Add a new person and telephone number (Insert)
SP_Delete user: Remove person (Delete) - delete row
SP_Update user: Change the person telephone (Update)

Other than the root, I have one user in MySQL. In order for the C# connection to work i need to give to the user:
1) under the Administration Tab - Global Privileges - SELECT
2) under the Schema Privileges - EXECUTE in '_people'.

When i try to remove the first one, the C# request to run any procedure is denied. I don't want to give 'Global Privileges - SELECT' to the c# app because it will have access to Select through all schemas.

I would like to give access to my C# app only to run the '_people' stored procedures. How can i do this?
