Macros | |
| #define | SQL_FN(F, N) &Function_factory<Instantiator<F, N>>::s_singleton |
| Shorthand macro to reference the singleton instance. More... | |
| #define | SQL_FACTORY(INSTANTIATOR) &Function_factory<INSTANTIATOR>::s_singleton |
| Shorthand macro to reference the singleton instance when there is a specialized instantiator. More... | |
| #define | SQL_FN_V(F, MIN, MAX) &Function_factory<Instantiator<F, MIN, MAX>>::s_singleton |
Use this macro if you want to instantiate the Item_func object like Item_func_xxx::Item_func_xxx(pos, args[0], ..., args[MAX]) More... | |
| #define | SQL_FN_V_THD(F, MIN, MAX) &Function_factory<Instantiator_with_thd<F, MIN, MAX>>::s_singleton |
Use this macro if you want to instantiate the Item_func object like Item_func_xxx::Item_func_xxx(thd, pos, args[0], ..., args[MAX]) More... | |
| #define | SQL_FN_V_LIST(F, MIN, MAX) &Function_factory<List_instantiator<F, MIN, MAX>>::s_singleton |
Use this macro if you want to instantiate the Item_func object like Item_func_xxx::Item_func_xxx(pos, item_list) More... | |
| #define | SQL_FN_LIST(F, N) &Function_factory<List_instantiator<F, N>>::s_singleton |
Use this macro if you want to instantiate the Item_func object like Item_func_xxx::Item_func_xxx(pos, item_list) More... | |
| #define | SQL_FN_V_LIST_THD(F, MIN, MAX) &Function_factory<List_instantiator_with_thd<F, MIN, MAX>>::s_singleton |
Use this macro if you want to instantiate the Item_func object like Item_func_xxx::Item_func_xxx(thd, pos, item_list) More... | |
| #define | SQL_FN_ODD(F, MIN, MAX) |
| Just like SQL_FN_V_THD, but enforces a check that the argument count is odd. More... | |
| #define | SQL_FN_EVEN(F, MIN, MAX) |
| Just like SQL_FN_V_THD, but enforces a check that the argument count is even. More... | |
| #define | SQL_FN_INTERNAL(F, N) &Internal_function_factory<Instantiator<F, N>>::s_singleton |
| Like SQL_FN, but for functions that may only be referenced from system views. More... | |
| #define | SQL_FN_INTERNAL_V(F, MIN, MAX) &Internal_function_factory<Instantiator<F, MIN, MAX>>::s_singleton |
| Just like SQL_FN_INTERNAL, but enforces a check that the argument count is even. More... | |
| #define | SQL_FN_LIST_INTERNAL(F, N) &Internal_function_factory<List_instantiator<F, N>>::s_singleton |
| Like SQL_FN_LIST, but for functions that may only be referenced from system views. More... | |
| #define | SQL_FN_LIST_INTERNAL_V(F, MIN, MAX) &Internal_function_factory<List_instantiator<F, MIN, MAX>>::s_singleton |
| Like SQL_FN_LIST, but enforces a check that the argument count is within the range specified. More... | |
