Re: [cmis-comment] CMIS11

Vedran, thank you for your question. While the CMIS Technical Committee has been closed for a couple of years now, many of the former members remain subscribed to this mailing list. I hope that someone will be able to help you out.Â

Best regards,Â

Hi,

I am implementing Query part of CMIS 1.1 specification at the moment and I am trying to figure out how to define FROM clause correctly (I am using Javacc for generating AST).

Here is how it is defined by the CMIS 1.1 specification:
2.1.14.2 Query Language Deïnition
FROM [virtual table names] - Âaccording to this, we should be able to specify multiple virtual table names

2.1.14.2.1ÂBNF Grammar

<fromÂclause>Â::=ÂFROMÂ<tableÂreference>Â
<tableÂreference>Â::=Â<tableÂname>Â[Â[ÂASÂ]Â<correlationÂname>Â]Â|Â<joinedÂtable>Â
<joinedÂtable>Â::=Â"("Â<joinedÂtable>Â")"Â
ÂÂ|Â<tableÂreference>Â[Â<joinÂtype>Â]ÂJOINÂ<tableÂreference>Â<joinÂspecification>Â
<joinÂtype>Â::=ÂINNERÂ|ÂLEFTÂ[ÂOUTERÂ]Â
<joinÂspecification>Â::=ÂONÂ<columnÂreference>Â"="Â<columnÂreference>Â

â

Problem

Looking at the <from clause> specified in CMIS 1.1 chapter 2.1.14.2.1ÂBNF Grammar I do not see how specifying multiple virtual table names is possible.

e.g. FROM table1, table2 ...

I may be missing on something hereÂso any help would be greatly appreciated.

Thanks in advance.
