Subject [jira] [Created] (SIS-328) EPSG factory on PostgreSQL fails because of missing cast
Date Tue, 28 Jun 2016 14:13:57 GMT
Martin Desruisseaux created SIS-328:

             Summary: EPSG factory on PostgreSQL fails because of missing cast
                 Key: SIS-328
             Project: Spatial Information Systems
          Issue Type: Bug
          Components: Referencing
    Affects Versions: 0.7
         Environment: PostgreSQL
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux
             Fix For: 0.8

The EPSG factory works as expected on Derby. But attempt to use the factory on PostgreSQL
sometime produces the following error message:

ERROR: operator does not exist: epsg."CRS Kind" ~~ unknown
SQL state: 42883
Hint: No operator matches the given name and argument type(s). You might need to add explicit
type casts.

The issue occurs in expressions like {{coord_ref_sys_kind LIKE 'projected%'}} with the {{coord_ref_sys_kind}}
column defined as an enum when Apache SIS is using PostgreSQL. The fix is to cast the {{CRS
Kind}} enum to {{VARCHAR(24)}}. The bug does not happen in Derby because that column is already
a {{VARCHAR(24)}} since Derby does not support enums.
