When one sees this pair of codes ER_CONST_EXPR_IN_VCOL and
ER_ROW_EXPR_FOR_VCOL,
one can't help asking himself whether that's the only disallowed
expressions,
and if not, do we have error codes for vcol expressions with
- user variables
- subqueries
- SP calls
- etc, etc.
Do we handle such cases at all?
Hello,
I checked our implementation and the Oracle and MS SQL Server documentation
. We disallow subqueries, stored procedures and functions, but we allow user
variables. The other database products are mostly stricter than we are, and
I opened a new bug regarding the more relaxed rules in MariaDB and the
issues this can cause.
