----------------------------------
Summary: Improve identifier validation on MemberExpression and
ParameterExpression
Key: CALCITE-7726
URL: https://issues.apache.org/jira/browse/CALCITE-7726
Project: Calcite
Issue Type: Task
Reporter: Ruben Q L
ParameterExpression constructor only verifies if the name's first character is
a valid Java identifier start (but not the rest of the name). MemberExpression
construction does not even verify this. As a consequence, invalid identifiers
can reach the dynamically generated code, causing CompileException later at
runtime.
This should be checked earlier and fail as soon as possible with a meaningful
exception.
