 Description   

Hello I tried short example to try compatibility of Oracle with MariaDB but it's not work :

sql_mode = Oracle

create or replace function ean_13(P_Str In Varchar2) Return Varchar2 Is 
l_Sum Number; 
l_Multiple Number; 
Begin For I in 1..12 Loop
 
 If mod(i,2) = 0 Then
 
 l_Multiple := 3;
 
 Else l_Multiple := 1;
 
 End If;
 
 l_Sum := Nvl(l_Sum, 0) + Substr(P_Str, i, 1) * l_Multiple; End Loop; 
If Floor(l_Sum/10) - Mod(l_Sum, 10) = Substr(P_Str, 13) Then Return('TRUE');
 
Else Return('FALSE'); 
End If; 
End; /

It appears to be a limitation of the current implementation. There is a separate task for support of IN/OUT for functions, it hasn't been done yet: MDEV-10654

bar, it probably needs to be documented somehow here.

Correct, IN/OUT parameter data types are not supported yet in Functions.

After removing "IN", this script creates the function:

SET sql_mode=ORACLE;
 
DELIMITER $$
 
create or replace function ean_13(P_Str Varchar2) Return Varchar2 Is
 
  l_Sum Number; 
  l_Multiple Number; 
Begin
 
 For I in 1..12 Loop
 
   If mod(i,2) = 0 Then
 
     l_Multiple := 3;
 
   Else l_Multiple := 1;
 
   End If;
 
 l_Sum := Nvl(l_Sum, 0) + Substr(P_Str, i, 1) * l_Multiple; End Loop; 
 If Floor(l_Sum/10) - Mod(l_Sum, 10) = Substr(P_Str, 13) Then Return('TRUE');
 
 Else Return('FALSE'); 
 End If; 
End;
 
$$
 
DELIMITER ;

i got a new error :

ERROR 1418 (HY000): This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)
