(:-)) In Oracle PL/SQL there are explicit restrictions on the size of variables. But you may simulate a half-side Turing tape easily with a suitable table (persistent or PL/SQL) and thus PL/SQL-Stored Procedures are Turing complete with the usual assumption that tables are as large as you want. > I don't know how realistic it will be in 2010, but > sooner or later a new generation of OO data bases will support ADT. > -- Frank Piron, defrankatkonaddot (leftrotate two)
