Sybase How to get dash separated date yyyy-mm-dd?

Question

I want to get date in such format yyyy-mm-dd, for example 2014-04-11. But it seems there is no way to do this in Sybase (ASE 12.5) with the convert function.

Currently, I get the date by 112 and add the - between digits. Any good way?

Answer 1

Try this:

select str_replace( convert( varchar, col1, 111 ), '/', '-') 
from table

Answer 2

Take advantage of format 140: yyyy-mm-dd hh:mm:ss.ssssss

Use char(10) to make Sybase truncate the string to just the first 10 characters, i.e.

convert(char(10), col1, 140)

Answer 3

Look the table documentation shared by Doberon, the table have all the formats. I try it and works nice:

SELECT convert(char(10),dateadd(month,-1, convert(date,getdate())),112)  from table;

My query format is yyyymmdd.
