- CHANGE: Modify addition so that previously-illegal combinations
TIME + TIME, TIME + DATETIME and DATETIME + TIME are now allowed. If
t1 and t2 are expressions of type TIME and dt is an expression of
type DATETIME, then the following are now equivalent (before, the
expressions on the left-hand side would fail with a "Type mismatch"
error.)
TIME + TIME, TIME + DATETIME and DATETIME + TIME are now allowed.
Also allow DATETIME - TIME. If t1 and t2 are expressions of type TIME
and dt is an expression of type DATETIME, then the following are now
equivalent (before, the expressions on the left-hand side would fail
with a "Type mismatch" error.)
t1 + t2 == t1 + coerce("INT", t2)
dt + t2 == dt + coerce("INT", t2)
t1 + dt == coerce("INT", t1) + dt
dt - t2 == dt - coerce("INT", t2)
- DOC FIX: Document previously-undocumented $MaxStringLen system variable
