Hello all.
I'm working on a kind of permissions management and I would like to
add restrictions on SELECT statements depending on certain fields of
a row.
tablename :
id,
perm_field1,
..
..
perm_field2,
data_field1,
data_field2,
...
Do you know if it is possible to write such things :
SELECT * FROM tablename WHERE permission(some parameters) == TRUE;
with the function 'permission' returning TRUE or FALSE after a check
on different perm_fields of the current row.
My problem is that I don't really know how to access to the fields of
the current row with an external function.
How could I write this ?
Thx for help.
