Labels: pull-request-available (was: )
> Parser loses position information for Expression3
> -------------------------------------------------
>
> Key: CALCITE-6502
> URL: https://issues.apache.org/jira/browse/CALCITE-6502
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.37.0
> Reporter: Mihai Budiu
> Priority: Minor
> Labels: pull-request-available
>
> Parser.jj features the following code snipped in the Expression3 production:
> {code:java}
> if (list1.size() == 1) {
> // interpret as single value or query
> return list1.get(0);
> }
> {code}
> This is problematic because the span of list1 is not the same as the span of
> its first element.
> This makes it look like the expression parsed does not include the opening
> and closing parens.
> This can be a problem for error reporting tools (but there are other use
> cases that may be impacted).
