The valid combinations of target data type and source data type in a `CAST` expression are given by the following table.
“Y” indicates that the combination is syntactically valid without restriction and “N” indicates that the combination is not valid.

Currently, the ANSI mode affects explicit casting and assignment casting only.
In future releases, the behaviour of type coercion might change along with the other two type conversion rules.
