Hi,
In this case is fine, but I need execute
begin work;
set isilation to repeatable read;
select * from table1
where codigo_tabla = "XX";
and lock this rows thar return this select, whether other user execute
begin work;
set isilation to repeatable read;
select * from table1
where codigo_tabla = "XX"
in this case the program will be show a messge that rows is locked for other user.
Thank you.
