Regexp Query.SUBJECT_PATTERN does not accept DISTINCT
-----------------------------------------------------
Key: JBSEAM-4761
URL: https://issues.jboss.org/browse/JBSEAM-4761
Project: Seam
Issue Type: Bug
Components: Framework
Affects Versions: 2.2.1.CR3
Environment:
http://fisheye.jboss.org/browse/Seam/branches/community/Seam_2_2/src/main/org/jboss/seam/framework/Query.java?r=11979
Reporter: Michael Keuchen
The current pattern in org.jboss.seam.framwork.Query
private static final Pattern SUBJECT_PATTERN =
Pattern.compile("^select\\s+(\\w+(?:\\s*\\.\\s*\\w+)*?)(?:\\s*,\\s*(\\w+(?:\\s*\\.\\s*\\w+)*?))*?\\s+from",
Pattern.CASE_INSENSITIVE);
does not accept queries using the keyword DISTINCT, for example:
SELECT DISTINCT vehicle FROM VEHICLE vehicle ...
Proposal:
Change the pattern to
"^select\\s+((distinct)?\\s+\\w+(?:\\s*\\.\\s*\\w+)*?)(?:\\s*,\\s*(\\w+(?:\\s*\\.\\s*\\w+)*?))*?\\s+from"
