Does RDS for MySQL Support Stored Procedures and Functions?
- Stored procedures and functions are a set of SQL statements that have been compiled and stored in databases. Invoking stored procedures and functions reduces data transmission between databases and application servers, and improves data processing efficiency.
- Differences between stored procedures or functions
- A function must have a return value, but a stored procedure does not.
- The parameters of a stored procedure can be of the IN, OUT, and INOUT type, but the parameters of a function can only be of the IN type.
For details about how to create a stored procedure and a function, see the official document.
