------------------------------------
Summary: 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
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).
