Attila Homoki commented on CASSANDRA-17667:
-------------------------------------------
_" why the removal of that code has no effect on comments :_ the code was just
a workaround to fix the original issue which was thet the order of the terminal
productions (aka field values) was incorrect.
_"Should we add ..." :_ also tested (manually) with the following field values
and these will work multiline comments.
[...]
<closedComment> ::= /[/][*].*[*][/]/ ;
<unclosedComment> ::= /[/][*].*$/ ;
<closedTComment> ::= /[/][@].*[@][/]/ ;
<unclosedTComment> ::= /[/][@].*$/ ;
<unclosedPgString>::= /\$\$(?:(?!\$\$).)*/ ;
<unclosedString> ::= /'([^']|'')*/ ;
<unclosedName> ::= /"([^"]|"")*/ ;

> Key: CASSANDRA-17667
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17667
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Interpreter
> Reporter: ANOOP THOMAS
> Assignee: Brad Schoening
> Priority: Normal
> Fix For: 4.0.x, 4.1.x, 5.x
>
>
> I use CQLSH command line utility to load some DDLs. The version of utility I
> use is this:
> {noformat}
> [cqlsh 6.0.0 | Cassandra 4.0.0.47 | CQL spec 3.4.5 | Native protocol
> v5]{noformat}
> Command that loads DDL.cql:
> {noformat}
> cqlsh -u username -p password cassandra.example.com 65503 --ssl -f DDL.cql
> {noformat}
> I have a line in CQL script that breaks the syntax.
> {noformat}
> INSERT into tablename (key,columnname1,columnname2) VALUES
> ('keyName','value1','/value2/*/value3');{noformat}
> {{/*}} here is interpreted as start of multi-line comment. It used to work on
> older versions of cqlsh. The error I see looks like this:
> {noformat}
> SyntaxException: line 4:2 mismatched input 'Update' expecting ')'
> (...,'value1','/value2INSERT into tablename(INSERT into tablename
> (key,columnname1,columnname2)) VALUES ('[Update]-...) SyntaxException: line
> 1:0 no viable alternative at input '(' ([(]...)
> {noformat}
> Same behavior while running in interactive mode too. {{/*}} inside a CQL
> statement should not be interpreted as start of multi-line comment.
> With schema:
> {code:java}
> CREATE TABLE tablename ( key text primary key, columnname1 text, columnname2
> text);{code}
