Need ability to push down LIMIT clause to Sybase
------------------------------------------------
Key: TEIID-2157
URL: https://issues.jboss.org/browse/TEIID-2157
Project: Teiid
Issue Type: Feature Request
Components: JDBC Connector
Affects Versions: 7.7.1
Reporter: Van Halbert
Assignee: Johnathon Lee
Fix For: 7.7.1
Want to add the ability to push down LIMIT clause to Sybase, but it is not
supported as of now, becasue the LIMIT translation capability is
disabled.
SybaseExecutionFactory#supportsRowLimit returns false and it is
hard-coded. If it returns true, EDS can push down
LIMIT to Sybase translating it to TOP clause, since SybaseExecutionFactory has
translateLimit
method which translate the LIMIT to TOP clause. The customer want a
property which can be switched on the limit translation easily than
writing java code.
