Hello,
I did the following: select first 1 cast(d_ein || ' ' || z_ein as timestamp) as tmp from t_zeitschaltuhr order by tmp into :tmp_next_e; select first 1 cast(d_aus || ' ' || z_aus as timestamp) as tmp from t_zeitschaltuhr order by tmp into :tmp_next_a; d_ein is a date, z_ein a time, I would like a timestamp and get the next after now. (Time to switch the machine next time off and on: This time should be the next in the future, so I thought: where tmp > 'now' , but I can't use the alias for the condition. What can I do? Thanks a lot. Best regards. Olaf [Non-text portions of this message have been removed]
