sql - MySQL How to INSERT INTO [temp table] FROM [Stored Procedure]

This is very similar to question 653714, but for MySQL instead of SQL Server.

Basically, I have a complicated select that is the basis for several stored procedures. I would like to share the code across the stored procedures, however, I'm not sure how to do this. One way I could do this is by making the shared select a stored procedure and then calling that stored procedure from the other ones. I can't figure out how to work with the result set of the nested stored procedure. If I could put them in a temp table I could use the results effectively, but I can't figure out how to get them in a temp table. For example, this does not work:

CREATE TEMPORARY TABLE tmp EXEC nested_sp();

The problem is, Stored Procedures don't really return output directly. They can execute select statements inside the script, but have no return value.

MySQL calls stored procedures via CALL StoredProcedureName(); And you cannot direct that output to anything, as they don't return anything (unlike a function).

MySQL Call Command
