Thomas Mueller created JCR-3376: ----------------------------------- Summary: TCK: SQLPathTest.testChildAxisRoot expected root node not in result Key: JCR-3376 URL: https://issues.apache.org/jira/browse/JCR-3376 Project: Jackrabbit Content Repository Issue Type: Improvement Reporter: Thomas Mueller Assignee: Thomas Mueller Priority: Minor
The TCK test SQLPathTest.testChildAxisRoot runs the following SQL-1 query: SELECT * FROM nt:base WHERE jcr:path LIKE '/%' AND NOT jcr:path LIKE '/%/%' It expected the result to be /jcr:system, /testroot, /testdata It does not allow the implementation to return the root node ('/'). According to the specification, a JCR implementation may filter the root node, as noted by Randall Hauch - http://jackrabbit.510166.n4.nabble.com/TCK-SQLPathTest-testChildAxisRoot-td4655670.html - quote: " Section 6.6.5.1 ("jcr:like function") defines the semantics of the wildcard characters as generally used within LIKE predicates (and "jcr:like" in XPath): "As in SQL, the character '%' represents any string of zero or more characters, and the character '_' (underscore) represents any single character." while Section 8.5.2.2 ("Pseudo-property jcr:path") specifies the semantics "jcr:path" pseudo column and narrows the semantics of using LIKE with "jcr:path" in the second-to-last bullet point: "Predicates in the WHERE clause that test jcr:path are only required to support the operators =, <> and LIKE. In the case of LIKE predicates, support is only required for tests using the % wildcard character as a match for a whole path segment (the part between two / characters) or within index brackets...." Because the '%' matches only a whole path segment, the "/%" literal only matches paths that have at least one path segment, which means that it matches all descendants of the root node. " the specification says "In the case of LIKE predicates, support is only required for tests using the % wildcard character as a match for a whole path segment (the part between two / characters)..." but it doesn't specify it needs to do so. To allow an implementation to return the root node, I suggest to change the test as follows: ... AND NOT jcr:path LIKE '/%/%' AND jcr:path <> '/' -- This message is automatically generated by JIRA.
