Subject: [OASIS Issue Tracker] Created: (CMIS-695) Escaping section shouldspecify which BNF symbols it applies to
Escaping section should specify which BNF symbols it applies to
---------------------------------------------------------------
Key: CMIS-695
URL: http://tools.oasis-open.org/issues/browse/CMIS-695
Project: OASIS Content Management Interoperability Services (CMIS) TC
Issue Type: Bug
Components: Domain Model
Affects Versions: V1.0 Errata
Reporter: Steve Roth
Priority: Minor
The escaping section currently says:
2.1.10.3 Escaping
Repositories MUST support the escaping of characters using a backslash (\) in the query statement. The backslash character (\) will be used to escape characters within quoted strings in the query as follows:
1. \' will represent a single-quote(') character
2. \ \ will represent a backslash (\) character
3. Within a LIKE string, \% and \_ will represent the literal characters % and _, respectively.
4. All other instances of a \ are errors.
From the above, it's not clear which BNF symbols this applies to.
For example, does this apply only to <character string literal>?
Does it also apply to <text search expression> (since it happens to have quotes around it) and/or <phrase>? Phrase is handled separately in the CONTAINS chapter.
Additionally, does this apply to <folder id>, which is itself a <character string literal>, or does "within quoted strings" apply only to quoted literal strings?
