Subject [jira] [Updated] (CAY-1577) SQL queries for LIKE expressions with escape character generated with syntax errors
Date Fri, 03 Jun 2011 10:49:55 GMT

     [ https://issues.apache.org/jira/browse/CAY-1577?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dzmitry Kazimirchyk updated CAY-1577:
-------------------------------------

    Attachment: escape-char.patch

Now generating queries like:

SELECT * FROM ARTIST t0 WHERE UPPER(t0.ARTIST_NAME) LIKE UPPER(?) {escape '*'} [bind: 1->ARTIST_NAME:'A*_1']

which works fine on HSQLDB, H2, Derby and SQL Server.

> For LIKE expressions with a usage of escape characters Cayenne generates SQL queries
such as
> SELECT * FROM TEST_TABLE t0 WHERE UPPER(t0.NAME) LIKE UPPER(? {escape '*'}) [bind: 1->NAME:'A*_1']
> which causes SQLException with message "Incorrect syntax near the keyword 'escape'."
