Re: Conversion from Sybase ASA

select 'T' as src,(if tbon is null or tbon < '1900/12/12' or tbon > '1900/9/30' then 'U' else 'P' endif) as pres from ftrans

select 'T' as src,(CASE WHEN tbon is null or tbon < '1900/12/12' or tbon > '1900/9/30' THEN 'U' ELSE 'P' END) as pres from ftrans

I think it works in Oracle too :)
Pay attention at tbon < '1900/12/12'. Try to use conversion on date formats like to_date() or to_timestamp().

Good luck

Subject: [SQL] Conversion from Sybase ASA

In sybase I can use the following syntax:

select 'T' as src,(if tbon is null or tbon < '1900/12/12' or tbon > '1900/9/30' then 'U' else 'P' endif) as pres from ftrans

this returns two columns: src = 'T' and pres which has either the value 'U' or 'P'

how would I express this in postgresql?

thanks
