1) Open DBSYS
2) Create a table with a field of type date and a field of type time
3) Insert a record with valid values

Now use sql-query and try:

select cast(datefield as char(8)) + " " + cast(timefield as char(8))
from testtable

The result is okay.

Now try:

select cast(datefield as char(5)) + " " + cast(timefield as char(5))
from testtable

the date string is 6 char long and the time string only 4 char

And this way:

select cast(datefield as char(9)) + " " + cast(timefield as char(7))
from testtable

gives the same result as the first query.
