> Key: TEIID-3555
> URL: https://issues.jboss.org/browse/TEIID-3555
> Project: Teiid
> Issue Type: Bug
> Components: JDBC Connector
> Affects Versions: 8.9.1
> Reporter: Bram Gadeyne
> Assignee: Steven Hawkins
> Fix For: 8.12
>
>
> 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.
