How to convert a string to a date in sybase

Question

I need to specify a date value in a sybase where clause. For example:

select * 
from data
where dateVal < [THE DATE]

Answer 1

102 is the rule of thumb, convert (varchar, creat_tms, 102) > '2011'

Answer 2

Here's a good reference on the different formatting you can use with regard to the date:

Answer 3

Several ways to accomplish that but be aware that your DB date_format option & date_order option settings could affect the incoming format:

Select 
   cast('2008-09-16' as date)
   convert(date,'16/09/2008',103)
   date('2008-09-16')
from dummy;

Answer 4

Use the convert function, for example:

select * from data 
where dateVal < convert(datetime, '01/01/2008', 103)

Where the convert style (103) determines the date format to use.
