             Summary: Like expression in select statement fails against Sybase
                 Key: TEIID-3555
                 URL: https://issues.jboss.org/browse/TEIID-3555
             Project: Teiid
          Issue Type: Feature Request
    Affects Versions: 8.9.1
            Reporter: Bram Gadeyne
            Assignee: Steven Hawkins
            Priority: Minor


Sometimes I use a like statement within the select statement to evaluate whether or not some text contains a certain sub-string. e.g:
 
select outcome like '%died%' as died
from patients
 
Some databases support this and return a boolean value but others (like sybase) don't. This results in an exception "Incorrect syntax near keyword 'like'"
 
Would is be possible to rewrite this for Sybase (and maybe others) to something like:
select case when icuoutcomename like '%overleden%' then cast(1 as bit) else cast(0 as bit) end as mort
from patients
 
I used cast(1 as bit) and cast(0 as bit) here because it seems like Sybase does not support true and false.
