Can a MySql stored procedure / function return a table without the use of temp table?
Creating the following procedure
CREATE PROCEDURE database.getE
As for now, this is not possible.
Here is the documentation on what may be used in the FROM
clause:
table_references:
table_reference [, table_reference] ...
table_reference:
table_factor
| join_table
table_factor:
tbl_name [[AS] alias] [index_hint)]
| table_subquery [AS] alias
| ( table_references )
| { OJ table_reference LEFT OUTER JOIN table_reference
ON conditional_expr }
join_table:
table_reference [INNER | CROSS] JOIN table_factor [join_condition]
| table_reference STRAIGHT_JOIN table_factor
| table_reference STRAIGHT_JOIN table_factor ON conditional_expr
| table_reference {LEFT|RIGHT} [OUTER] JOIN table_reference join_condition
| table_reference NATURAL [{LEFT|RIGHT} [OUTER]] JOIN table_factor
join_condition:
ON conditional_expr
| USING (column_list)
index_hint:
USE {INDEX|KEY} [FOR JOIN] (index_list)
| IGNORE {INDEX|KEY} [FOR JOIN] (index_list)
| FORCE {INDEX|KEY} [FOR JOIN] (index_list)
index_list:
index_name [, index_name] ...
As you can see, stored procedures are not in this list.
