Hello,
i´m using the 3.23.57 version and i´ve declared a native function, but when
i call it (SELECT GETUPDATE(1);) i
get this line
ERROR 1064: You have an error in you SQL syntax near '(1)' at line 1;
I think i´ve followed all the steps right:
1)added the line in lex.h
{"GETUPDATE" ...)
2)added this line to item_create.h
Item *create_func_getupdate(Item* a);
3)added this definition to item_create.cc
Item *create_func_getupdate(Item* a){
return new Item_func_getupdate(a);}
4)added this to item_func.h
class Item_func_getupdate :public Item_num_func
{
public:
Item_func_getupdate(Item *a) :Item_num_func(a) {}
const char *func_name() const { return getupdate"; }
double val();
longlong val_int();
enum Item_result result_type () const { return INT_RESULT; }
void fix_length_and_dec() { decimals=0; max_length=21; }
};
5) and at last added this to item_func.cc
longlong Item_func_getupdate::val_int()
{
FILE *fic;
fic = fopen("gus.txt","w");
fprintf(fic,"Ejecucion \n");
fclose(fic);
return 0;
}
as you may see it´s a simple program which the only thing it has to do it´s
printing
that line (in the future it will do more things, but until then...).
I really need help because this is getting on my nerves!
Anyways, thank you very much!
