[teiid-issues] [JBoss JIRA] (TEIID-2930) SCROLL keyword for DECLARE CURSOR not being parsed correctly

[Johnathon Lee (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-2930?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Johnathon Lee reopened TEIID-2930:
----------------------------------



I have used isql and ODBC driver for RHEL5. 

I am not able to force isql to generate "..scroll cursor for..", however when I type the query[1] directly into isql, it is processed by teiid correctly. So the fix seems to be ok.

However the query[2] fails and teiid throws an exception[3]

Syntax "cursor with hold for" works correctly for the unpatched version of EDS 5.3.1 so I consider it as a regression. 


[1]  declare "SQL_CUR0x11ad4120" scroll cursor for select intNum from bqt2.smalla;fetch 100 in "SQL_CUR0x11ad4120"

[2] declare "SQL_CUR0xe61c20" cursor with hold for select * from pg_proc

[3] org.teiid.jdbc.TeiidSQLException: Direct usage of XQuery is no longer supported, use XMLQUERY instead.

> The DECLARE cursor is defined as [1]. However, in [2] line #155, the SCROLL keyword is not being matched.  Correction would be to match the pattern fully as defined in [1]
